In numerous instances, Lelouch had exposed his true identity to several individuals, whether by accident or he had done so willingly. Some of those individuals had already known his true identity.
However, during the events of "R2: Revolution, Chapter 32: The Demon and Dragon Cometh", when Lelouch vi Britannia himself had been notified by Megatron himself that he and his forces are on their way to Horai Island with the Damocles under his control, Lelouch had made the choice to finally reveal his true identity to everyone on Horai Island. Essentially, revealing the big secret that Zero's true identity is Lelouch vi Britannia, the thought to be deceased 11th Prince of the Holy Britannian Empire, to the entirety of the Autobot/Black Knight Alliance. Regardless, thanks to his rousing speech, everyone on Horai Island had expressed their desire to fight against the incoming threat and support Zero himself regardless of the odds that are seemingly against the alliance themselves.
Optimus Prime, Ratchet, Arcee, Cliffjumper, Bulkhead, Ironhide, Bumblebee and Fixit[]
The very first Autobots Lelouch meets. He showed them the design of his first costume which would be his original physical appearance as Zero. Although they had expressed some degree of awkwardness and surprise towards how flashy his intended costume looks like, they had respected his decision in choosing such a costume to wear in order to hide his identity. Thus, they had participated in helping Lelouch to make his original costume which would, in turn, enable them to become the very first individuals who knew that Lelouch was Zero. (R1, Chap 5)
C.C./Cera[]
The mysterious light green-haired girl who gave Lelouch his Geass. She had surprised him by visiting the Ashford Academy's Student Government Clubhouse where both Lelouch and Nunnally had been staying in ever since the world had falsely believed that they had died during the Invasion of Japan thanks to the support of the Ashford Family who were friends with their late mother, Marianne vi Britannia, sometime after the incident at the Shinjuku Ghetto had passed as Lelouch had initially presumed her to be dead due to herself being shot in the forehead by one of the late Clovis la Britannia's soldiers when they were carrying out the incident in question.
Out of shock, he had questioned her regarding her origins and true nature as well as the developing possibility that she would put Nunnally in danger if her association with Lelouch ever gets out. Not only that, he had no choice but to take her to the Autobots' base where she is finally privy about the existence of the Autobots. Though she initially has a tense and rough relationship with both Lelouch and the Autobots, she, at least, was understanding enough to not expose Lelouch's identity as Zero or Lelouch vi Britannia as well as the existence of the Autobots to the public. (R1, Chap 6)
Megatron, Soundwave, Laserbeak, Ravage, Frenzy and Rumble[]
Soundwave was given the task of observing Suzaku Kururugi by Megatron as Megatron intends to make use of Suzaku due to the leader of the Decepticons himself thinking that the aforementioned young man might attract Optimus Prime's interests. However, as Soundwave is carrying out his assigned task, both himself and Laserbeak had managed to capture concrete proof which not only verifies that "Lelouch Lamperouge" is actually Zero's true identity. Subsequently, Soundwave had also managed to gather proof which verifies Lelouch's true identity as Lelouch vi Britannia, the exiled and thought to be deceased 11th prince of the Holy Britannian Empire. As a result, Soundwave had also verified the true identity of Lelouch's younger sister, Nunnally Lamperouge, as, Nunnally vi Britannia, the also exiled and thought to be deceased princess of the Holy Britannian Empire. As expected, Soundwave had proceeded to relay all of his discoveries regarding Lelouch's and Nunnally's true identities and statueses to Megatron himself.
Initially, both Megatron and Soundwave had agreed to keep what they had discovered about the two individual in question to themselves. Thus, they are the very first Decepticons who knew Lelouch's true identities as both Zero and the thought to be deceased 11th prince of the Holy Britannian Empire. In addition to that, due to how close Soundwave's minicons (Laserbeak, Ravage, Frenzy and Rumble) are to him at the time of said revelation, it is safe to assume that they are also the first Decepticons who knew Lelouch's true identities as well but had also kept it a secret out of their loyalties to both Soundwave and Megatron. (R1, Chap 7)
The possibility of Megatron discovering his true identity as Zero and Lelouch vi Britannia has always been Lelouch's greatest fear. Unfortunately, said fear had became a reality when Megatron had forcefully transported Lelouch himself, Suzaku and C.C. to the burning and destroyed remains of Pendragon after the Decepticons' warship, the Nemesis, had razed the entire capital city itself before he subsequently proceeded to reveal his knowledge regarding Lelouch's true identities in front of a whole crowd of Decepticons before all 3 individuals themselves then start their supposed "final showdown" against the leader of the Decepticons himself. (R1, Chap 35)
Rai Kururugi/Kaizaren von Britannia[]
An amnesiac young man who had stumbled upon Ashford Academy while initially wearing a similar outfit that C.C. had worn as part of her physical appearance. Since then, he had been staying at Lelouch's and Nunnally's residence due to Lelouch's insistence since the aforementioned young man had found him. However, one night, after Lelouch had returned from resolving the situation between Kallen Kozuki and her mother, he had came across Rai who had stumbled upon him washing himself up as Rai was getting himself a drink.
Thus, Rai had finally seen the truth. The truth of Lelouch being the true identity of Zero as well as Lelouch's car being one of the Autobots in disguise along with meeting C.C. for the first time. Not only that, Rai had instantly understood why Lelouch is doing this. Fortunately, Rai had also stated that he had intended to search for Zero so that he could join the Autobot/Black Knight Alliance due to Rai himself wanting to take a stand against the Holy Britannian Empire for their mistreatment towards the "Numbers". (R1, Chap 10)
Wheeljack[]
After the Autobots and the Black Knights had finally dealt with the incident that involved the Decepticon shifter known as Makeshift, Bulkhead had told Wheeljack everything regarding Lelouch being Zero, Lelouch's and Nunnally's life stories as well as Lelouch's Geass due to Bulkhead himself not wanting to keep any secrets from Wheeljack. Though Lelouch was shocked, at first, he had understood that Bulkhead had meant no harm in doing so and Bulkhead had even gave Lelouch some advice regarding opening up to his fellow Black Knights under the assumption that they would understand what he has gone through. (R1, Chap 14)
Kallen Kozuki/Stadtfeld[]
The most talented Knightmare pilot among the Autobot/Black Knight Alliance's best pilots. Originally, she did not know that both Lelouch and Zero are the same person albeit she was suspicious of Lelouch's act of somehow knowing what exactly happened in the Shinjuku Ghetto when he was using his Geass on her for the first time which had made him be aware of his Geass' limits but she didn't think much of it. However, thanks to listening to Rai's talk to Cera, Lelouch had decided to expand his circle of trust by coming clean with his identity as Zero to Kallen when she was looking for him.
After that, the Autobots, Rai and Lelouch himself had proceeded to lay down everything they know about Lelouch, Nunnally, Lelouch's Geass and C.C. so that she would understand. Fortunately, Kallen had agreed to keep it a secret from her fellow Black Knights including her oldest friend, Kaname Ohgi, out of gratitude for everything he did for her and her mother throughout the past few months. (R1, Chap 16 to Chap 17)
Shockwave[]
One of Megatron's top lieutenants and his most eminent scientist. Upon making his arrival on Earth as well as revealing his survival to the Decepticons, Megatron had tasked Soundwave with filling him on recent events. As a result, Soundwave had revealed Lelouch's true identity as Zero to Shockwave but Shockwave had agreed to keep it a secret from his fellow Decepticons due to a combination of his loyalty to Megatron as well as Megatron's logical explanation regarding the potential of using said secret to maintain an advantage over their enemies should the right opportunity presents itself. (R1, Chap 17)
Taizo Kirihara, Kaguya Sumeragi, Kaname Ohgi and Shinichiro Tamaki[]
During a meeting with 2 members of the 6 Houses of Kyoto who were a group of Japanese nobles who had taken advantage of their association with the Holy Britannian Empire in order to secretly supply Japanese resistance groups, Lelouch, under his guise as Zero, had recognized Taizo's and Kaguya's voices behind the veils that they were using to keep their identities a secret. Thus, he had revealed his knowledge regarding who they truly are before he subsequently reveals his true identity as Lelouch vi Britannia to them.
Once both Taizo and Kaguya had gotten themselves reacquainted with the young man that they had met during the days when both Lelouch himself and his younger sister, Nunnally, had spent in Japan after they were exiled before Britannia's invasion of said nation, both Lelouch and Optimus Prime had proceeded to reveal everything they know about the Holy Britannian Empire and the Decepticons.
Not only that, both Kaname and Shinichiro were there, at the time, when Lelouch had revealed his true identity to both Taizo and Kaguya. However, at the time, both Kaname and Shinichiro had just assumed that Lelouch is just a normal high school boy who truly hates the Holy Britannian Empire for their cruel and ruthless ways in spite of himself being a Britannian as well as Taizo himself being willing to vouch for him regarding the importance of Lelouch hiding his own identity from his comrades which had helped both Kaname and Shinichiro in maintaining their loyalty to him. (R1, Chap 17)
However, after the Autobot/Black Knight Alliance had helped the 4 Holy Swords rescue their leader, Kyoshiro Tohdoh, both Kaname and Shinichiro had finally witnessed Lelouch revealing his true identity as Lelouch vi Britannia, the exiled and thought to be deceased 11th prince of the Holy Britannian Empire to Kyoshiro Tohdoh, The 4 Holy Swords (Nagisa Chiba, Shogo Asahina, Kosetsu Urabe and Ryoga Senba), Tatewaki Katase, Rakshata Chawla and Diethard Reid. Nevertheless, they had chose to continue to follow Lelouch due to their loyalty to him as a result of seeing his actions during the incident involving the Scraplets a few months back. (R1, Chap 27)
Shirley Fenette[]
A young girl who is a fellow member of Ashford Academy's Student Council, she had a crush on Lelouch Lamperouge himself. Initially, she was not aware of Lelouch's double life as Zero. However, everything changed when her father, Joseph Fenette, had been secretly kidnapped by the Decepticons as well as the Decepticons misleading both Shirley and her mother into believing that he was killed during the Battle of Narita. Due to Villetta Nu's manipulations, Shirley was manipulated into thinking that Lelouch is a member of the Black Knights, the group who had caused her father's "death". However, when she had gotten involved in the Battle of Port Yokosuka, Lelouch had no choice but to save her which had caused him to be knocked out by Starscream's attack. At that moment, Shirley is prepared to kill Zero in order to avenge her "late" father but when his mask had slipped off of his head which had, in turn, revealed his face, Shirley was shocked at the aforementioned revelation.
Villetta who had followed Shirley closely behind had also seen Lelouch's true face and gleefully proclaiming what kind of execution will Zero receive. However, when Shirley is about to shoot Villetta in order to protect Lelouch as well as Villetta about to attack Shirley, Bumblebee had managed to quickly arrive at the scene just in time as well as shoot Villetta with his Energon blaster before taking both Lelouch and Shirley from the scene along with scaring Shirley off once Bumblebee had dropped her off.
The revelation of Shirley managing to see his true face had reached Lelouch himself, Kallen, Rai and all of the Autobots. After they had managed to rescue her from Mao when he had decided to take advantage of her insecurities in order to help him get C.C., both Lelouch and Rai had proceeded to tell her everything. After that, both boys in question then proceeded to introduce her to C.C. and the Autobots. Eventually, she had made the decision of joining the Autobot/Black Knight Alliance. (R1, Chap 17 to Chap 20)
Mao[]
According to Optimus Prime's theories, Mao had been spying on Lelouch and C.C. for quite some time before his first major appearance in "R1: Rebellion, Chapter 19: What is Evil?" due to his obsession with C.C. herself. As a result of his Geass and his surveillance, Mao had managed to figure out Lelouch's true identity as both Zero and Lelouch vi Britannia with Mao intending to use his acquired knowledge to get Lelouch out of the way so that he could have C.C. all to himself. He had even approached the Decepticons with the promise of dealing with Zero and Optimus Prime as well as giving them some knowledge regarding the power called Geass in return for the Decepticons giving both himself and C.C. a home on the Moon where they would be away from all humans on Earth so that he would no longer be tormented by so many voices thanks to his uncontrollable Geass.
However, when another attempt to defeat Lelouch had resulted in Mao being permanently rendered to be unable to speak at all, Mao had no choice but to escape and return to the Decepticons. Unfortunately, for him, Megatron had revealed to him that he already knew about Lelouch's true identities. Thus, Mao had ended up being taken by Shockwave so that the Decepticons' most eminent scientist himself could experiment on him in order to find out about the nature of Geass which could help the Decepticons further their cause. (R1, Chap 19 to Chap 20 as well as Chap 23)
Kyoshiro Tohdoh, The 4 Holy Swords (Nagisa Chiba, Shogo Asahina, Kosetsu Urabe and Ryoga Senba), Tatewaki Katase, Rakshata Chawla and Diethard Reid[]
Even before the incident when the Autobot/Black Knight Alliance had helped the 4 Holy Swords to rescue him from Britannia's clutches, Kyoshiro Tohdoh had already suspected that Zero is actually Lelouch vi Britannia in disguise with Lelouch's aforementioned revelation confirming his suspicions on the matter in question. It was a big shock to everyone who had witnessed it, at the time, with the exception of Rakshata Chawla who just expressed minor amusement at the aforementioned revelation due to the proven existence of Cybertronians while Diethard Reid had expressed glee and excitement towards such a shocking revelation. Nevertheless, both the Autobots and the Black Knights as well as both Tohdoh and Kaguya had vouched for Lelouch's sincere desire of destroying the Holy Britannian Empire which had, in turn, earned the loyalty of the Japan Liberation Front's members as they are included as part of the Autobot/Black Knight Alliance's membership. (R1, Chap 27)
Euphemia li Britannia[]
The 3rd Princess of the Holy Britannian Empire who is one of Lelouch vi Britannia's half-sisters as well as being the one sister that he had cared about as almost as much as Nunnally vi Britannia.
When Zero, Optimus Prime, Euphie, Bumblebee, Rai, Nonette Enneagram, Suzaku Kururugi, Dreadwing and Kallen had been transported to Shikine Island via V.V.'s secret actions as well as the group of individuals in question having been split up and landed on different parts of the island itself, both Zero and Optimus Prime had came across Euphie. Euphie then voices her suspicions that she knows that Zero is Lelouch before Lelouch proceeds to remove his mask which had made Euphie express her happiness at seeing him again with Lelouch returning said feelings.
Both long lost half-siblings then proceed to happily catch up with each other with Lelouch telling Euphie that Nunnally is alright albeit she doesn't know that Lelouch has been acting as Zero yet as well as Lelouch making it clear that he hates their father, Charles zi Britannia, not Euphie herself as she is one of the kindest members of the royal family that he knows. Euphie, in return, expresses relief that Lelouch doesn't hate her as well as gratitude that Optimus Prime had taken good care of her beloved half-brother.
Not only that, after Euphie had confessed to both Lelouch and Optimus Prime about her fear towards Megatron himself as well as expressing curiosity about how did the Great War back on Cybertron had even started, Optimus himself then proceeded to tell both Lelouch and Euphie the full story regarding the events that had led to the Great War back on Cybertron as well as the events that had led to the Great Exodus which had, in turn, motivated Euphie to carry out several actions out of her sympathies towards the Autobots as well as trying to sway both her knight, Suzaku Kururugi, Dreadwing and her elder sister, Cornelia li Britannia, to not be affiliated with the Decepticons anymore. (R1, Chap 28)
V.V./Victor zi Britannia[]
As a result of having faked his death with the help of his younger twin brother, Charles zi Britannia, and his sister in law, Marianne vi Britannia, beforehand along with acquiring a Code that enables him to be immortal which had locked him in the age of a 10 year old boy, he had been spying on Lelouch from behind the scenes throughout the majority of R1: Rebellion. Thus, he knows about Lelouch's double life as Zero. Not only that, after he had transported him, Optimus, Dreadwing, Suzaku as well as a few other enemies, he had approached Megatron with the intention of manipulating him into dealing with both Lelouch and Optimus.
However, he had made the grave mistake of underestimating Megatron as Megatron had already known about Lelouch's true identity beforehand as well as already being suspicious of V.V.'s and Charles' secret plans throughout the past few years. Thus, V.V. was lured into a trap which had enabled Megatron to learn about everything about the two brothers' secrets including their end goal, the "Ragnarok Connection". As a result, V.V. was forced to undergo a series of events that had ended with his permanent death as a result of Megatron taking his Code.
Nunnally vi Britannia and Sayoko Shinozaki[]
After much consideration on whether he wants to tell her or not as well as not wanting to keep the truth from her, Lelouch had finally confessed to Nunnally that he is Zero with Nunnally revealing that she had known he was Zero ever since the incident when he and the Autobots had rescued Suzaku Kururugi from the Britannian Purist Faction's machinations but she didn't want to believe it. However, Lelouch's confessions had confirmed her denied suspicions.
Not only that, Lelouch had also confessed his true identity to Sayoko Shinozaki as his way of showing gratitude for her years of service in taking good care of both Lelouch and Nunnally. However, when he had confessed to her, Sayoko had proceeded to reveal that she had known all this time. She had suspected that Lelouch was actually Zero for quite a while and she had actually joined the Autobot/Black Knight Alliance recently due to herself being recruited by Diethard Reid as a spy.
As promised by Lelouch, once the Ashford Academy's school festival is over, both Nunnally and Sayoko had been transported to the Ark for their own safety where they had met the Autobots for the very first time. (R1, Chap 29)
Schneizel el Britannia and Starscream[]
The 2nd Prince of the Holy Britannian Empire as well as the Holy Britannian Empire's Prime Minister. With Starscream's help, he had approached Megatron with the intention of joining the Decepticons in order to finally destroy the Holy Britannian Empire and the Autobot/Black Knight Alliance as part of his misguided plan to bring eternal peace across the Earth in the form of helping the Decepticons become the rulers of said planet in order to oppress all humans. In order to appeal to Megatron, Schneizel had presented his theories and suspicions regarding why he thinks that Lelouch and Zero are the same person.
However, after he had presented his theories, Megatron had revealed that he had already known about said revelation beforehand which had greatly surprised Schneizel himself. Regardless, Megatron was willing to accept the 2nd prince himself into the Decepticons' ranks due to himself finding Schneizel as a worthy asset to the group as well as being intrigued by the 2nd prince's views and personality.
Starscream was there at the time when Megatron had revealed to Schneizel that he had already known about Lelouch and Zero being the same person. Thus, he was shocked regarding why Megatron did not tell Starscream, his own second in command, about this discovery of his beforehand with Megatron stating that if Starscream knows about it, his attempts at eliminating Lelouch himself as soon as possible will do more harm than good for the Decepticons with Schneizel vouching for Megatron's actions. (R1, Chap 31)
Milly Ashford[]
The student council president of Ashford Academy as well as being one of the few individuals who are aware of Lelouch's true identity as Lelouch vi Britannia due to her family, the Ashford Family, being close friends with Lelouch's late mother, Marianne vi Britannia.
During the academy's school festival, she had revealed to Lelouch that he knows about his secret double life as Zero due to herself connecting various clues which had helped her figure out his actions. However, she had not revealed her knowledge regarding Lelouch's double life as Zero to anyone due to her tense relationship with her mother as well as her choice of valuing her friendships with both Lelouch and Nunnally. Plus, she knows that he is a good person despite his demeanor. As Lelouch appreciated Milly's kindness, he also tells her that she needs to leave the Tokyo Settlement soon as the settlement is not going to be a safe place should the Decepticons make their first move. (R1, Chap 31)
Suzaku Kururugi and Dreadwing[]
Both Suzaku and Dreadwing had discovered Zero's true identity as Lelouch vi Britannia when Suzaku had attempted to kill him for destroying what Suzaku thought was Euphie. However, when Suzaku had declared his intent to kill Lelouch for killing what he thought was Euphie, Lelouch had managed to get Suzaku to see that the thing that was "Killed" was not actually Euphie. Instead, it was a pretender drone that was controlled by Megatron in order to carry out the Special Administrative Zone Massacre. Not only that, when Suzaku had finally confessed his desire to be killed just so that he can avoid responsibility for all the terrible things that he did, Lelouch had managed to convince him to join the Autobot/Black Knight Alliance so that he could properly atone for all of his crimes.
Not only that, Dreadwing had witnessed the aforementioned revelation as well. Thus, after witnessing Suzaku's and Lelouch's reconciliation, he proceeded to defect from the Decepticons and join the Autobots. In addition to that, while he, indeed, surprised by the aforementioned revelation, Dreadwing is not surprised by Lelouch's motives for taking on the mantle of Zero as he had read about his history beforehand. Plus, after Optimus had confirmed that Megatron had, indeed, destroyed their beloved home planet, Cybertron, as well as having killed his twin brother, Skyquake, for attempting to prevent his act that had sealed Cybertron's fate, Dreadwing had finally made his decision to join the Autobots official. (R1, Chap 32)
Cornelia li Britannia[]
The 2nd Princess of the Britannian Imperial Family as well as being one of Lelouch vi Britannia's half-sisters. During an expedition where she is working alongside a group of Decepticons as well as several members of the Knights of the Round. However, due to the machinations of the Decepticon known as Airachnid, both Cornelia and Starscream had ended up being captured by the Autobot/Black Knight Alliance.
During a subsequent interrogation session where Lelouch is questioning Cornelia regarding what truly caused his late mother's death, Lelouch had revealed his true identity to her as well as expressing his rage towards her abandonment of both himself and Nunnally. However, after being forced by Lelouch to tell him everything she knows about the event in question as well as expressing her true love towards both Lelouch and Nunnally, Zero was forced to use his Geass to command her to forget Zero's true identity. (R1, Chap 22)
A few months later, when the Special Administrative Zone Massacre had happened, Cornelia was forced to witness Zero's act of killing what she thought was her beloved younger sister, Euphemia li Britannia as well as rediscovering Zero's true identity as Lelouch vi Britannia. Fortunately, she had also taken a closer look at the "corpse" of her just killed "sister" which revealed that it's not really the real Euphie. It's a fake pretender drone that's controlled by Megatron in order to carry out the massacre itself. Her feelings of anger towards Megatron for using her younger sister's face to carry out such an atrocity, her feelings of fear towards what Megatron is going to do to both her half-siblings, Lelouch and Nunnally, as well as her subsequent feelings of remorse towards everything that she had done had motivated her to join the Autobot/Black Knight Alliance. (R1, Chap 32 to Chap 36)
Charles zi Britannia[]
The 98th emperor of the Holy Britannian Empire as well as Lelouch vi Britannia's father. He had secretly known about his son's actions as Zero as well as his interactions with the Autobots and the Black Knights. However, Charles had also developed a hatred towards Optimus Prime for influencing his son which had caused Lelouch to change for the better. Thus, he had originally assigned one of his Knights of the Round which happens to Bismarck Waldstein who is the Knight of One with the special mission of killing Optimus Prime as payback for making Lelouch forget who his "real" father was.
However, he was genuinely shocked by Megatron's confession. His confession regarding everything he had learned from V.V.'s mind including the fact that Charles himself was already aware of Zero's true identity as Lelouch vi Britannia as well as Charles' decision of not doing anything about it in order to prevent the Autobots from finding out about his, his elder twin brother's, Marianne vi Britannia's and C.C.'s plans regarding the Ragnarok Connection.
Bismarck Waldstein[]
One of the Knights of the Round as well as being the Knight of One. He was notified of Zero's true identity as Lelouch vi Britannia, Charles' thought to be deceased son. Bismarck was given the task of killing Optimus Prime and bring Lelouch to Charles alive due to Charles hating Optimus Prime for influencing Lelouch to change himself for the better which had caused Lelouch to forget his roots. (R1, Chap 31)
Akari Kozuki[]
She is Kallen's biological mother who is a Japanese citizen that had given birth to both Naoto and Kallen out of her union with a Britannian nobleman who is part of the Stadtfeld family but was forced to endure a life of abuse at the hands of Kallen's adoptive stepmother, Mrs Stadtfeld, as well as the other maids of the Stadtfeld household who were all pure Britannians but she had no choice but to bear it so that she would remain as close as possible to her own daughter albeit their relationship has became strained over the past few years. Eventually, the abuse was too much and she had to resort to taking the addictive psychotropic drug called Refrain as a way for her to bear her miserable life.
After an incident where Kallen was exposed to the revelation that her own mother had been taking Refrain as well as realizing that she had endured her stepmother's abuse for her sake, Lelouch, under his guise as Zero, who had also witnessed the aforementioned revelation, had pulled some strings in order to help both Kallen and her mother move out of the Stadtfeld household and into a nice apartment where they can finally live out a much happier life once Akari herself had finally been purged of the Refrain drug from her body.
However, even then, she was not aware of her own daughter's activities as a member of the Autobot/Black Knight Alliance. But, when the Special Administrative Zone Massacre had happened, she was worried about what happened to her own daughter as she was supposed to meet them at the stadium which serves as the location of the Special Administrative Zone of Japan, she was fortunately rescued by both Cliffjumper and Arcee as well as being taken to the Ark. While she was recovering there, Kallen had met her and had no choice but to tell her everything of importance including the fact that Zero's true identity is Lelouch vi Britannia, the thought to be deceased 11th prince of the Holy Britannian Empire. Even though she was worried about what's going to happen to her daughter due to Akari highlighting the fact that her own son, Naoto, had lost his life in a similar manner, Akari still possessed pride towards Kallen gaining so much as a result of her life as a member of the Autobot/Black Knight Alliance albeit she had to convince her daughter to promise her that she will be okay and she won't be killed during the upcoming battles in question which she did. (R1, Chap 33)
Nonette Enneagram, Monica Krushevsky, Llyod Asplund, Cecile Croomy, Rivalz Cardemonde and Nina Einstein[]
Nonette Enneagram was a member of the Knights of the Round as she was holding the title, Knight of Nine. She was originally the knight of Kaizaren von Britannia but she had presumed that he was dead when she had received news that he as well as his mother, Sakura Kururugi, who was Suzaku's aunt as well as his younger sister, Erina von Britannia, had been killed during the Invasion of the Philippines which had happened during the same time as the Invasion of Japan. However, even though she was shocked to find out that Kaizaren had amnesia by the time she had been informed by Charles zi Britannia of his survival, both individuals had sworn to protect each other from Britannia's and the Decepticons' machinations which had, in turn, restored their relationship in a state that's similar to the state that it was before the Invasion of the Philippines.
Monica Krushevsky was also a member of the Knights of the Round as she was holding the title, Knight of Twelve, along with being the leader of Charles zi Britannia's Royal Guard. However, due to her friendship with Milly Ashford, Nina Einstein and Rivalz Cardemonde, she had ended up saving them from a horde of Insecticons who are holding them hostage at the school as well as working alongside Shirley Fenette, Bumblebee and Ratchet in order to save them and defeat the Insecticons.
Llyod Asplund is the creator of Suzaku Kururugi's personal Knightmare Frame, the Lancelot, while Cecile Croomy was Llyod's assistant. When Suzaku had revealed the truth about the pretender drone that had started the Special Administrative Zone Massacre as well as his act of resigning from the Britannian Military in order to join the Autobot/Black Knight Alliance, both individuals in question had decided to defect to the alliance itself due to different reasons. For Cecile, she wants to help Suzaku and her conscience can no longer tolerate the Decepticons' and Britannia's injustices whereas for Llyod, he doesn't want his rival, Rakshata Chawla, to mess around with the Lancelot as he considers it his magnum opus.
Their subsequent shared decision of joining the Autobot/Black Knight Alliance had led to all of said individuals to discover that both Zero and Lelouch vi Britannia are the same person when Lelouch himself was brought to Ratchet's laboratory after he was affected by Megatron's Dark Geass of Absolute Terror. (R1, Chap 36)
Thundercracker and Skywarp[]
Two Decepticons who Starscream's fellow Seekers. They had heard Megatron himself outing Zero's true identity as Lelouch vi Britannia when he had brought him, C.C. and Suzaku Kururugi to the destroyed, burning remains of Pendragon in order to carry out a "final showdown" against them. (R1, Chap 35)
Villetta Nu/Chigusa[]
Originally, a member of the Britannian Purist Faction, she was a member of the aforementioned group in order to earn a title that would indicate her as a member of the Holy Britannian Empire's nobility due to herself not being of noble blood. Not only that, she had came across the aftermath of the event where Lelouch vi Britannia had used his Geass for the very first time and due to some clever thinking, Lelouch had managed to command Villetta into giving him her Sutherland so that he could quickly make his escape from the scene in question. (R1, Chap 3)
When her superior, Jeremiah Gottwald, was disgraced ever since Zero's and the Autobots' debut appearances, she was the only one who had stayed loyal to him due to herself noticing that Jeremiah himself was having a memory lapse due to Lelouch secretly using his Geass, under his guise as Zero, in order to release Suzaku Kururugi to the Autobot/Black Knight Alliance's custody as she herself is also experiencing something similar ever since the incident at the Shinjuku Ghetto. After she had witnessed Jeremiah Gottwald's apparent death during the Battle of Narita at the hands of Kallen Kozuki, Arcee and Cliffjumper, Villetta herself then begins to make her own move. (R1, Chap 15)
Noticing an image of Lelouch himself in a photo that's being kept in Shirley Fenette's phone when both Shirley and her mother had been called by her to identify a lab coat that belonged to Shirley's father in order to verify his "death" as well as vaguely remembering Lelouch's face, Villetta herself then made contact with the young girl in question so that she could take advantage of her in order to determine whether Lelouch is a member of the Autobot/Black Knight Alliance or not. She had even told Shirley about the Japan Liberation Front's battle at Port Yokosuka with a strong possibility that the Autobots and the Black Knights are going to be there to help the JLF out as part of her plans. Therefore, when Shirley had went to the aforementioned location, Villetta had followed her closely behind.
Thus, alongside Shirley, she was also a witness of Zero's true identity being revealed to be Lelouch Lamperouge. As she had gleefully stated her intentions of bringing the aforementioned young man to Princess Cornelia as part of her plans to become a noble as well as seeing what kind of execution is a good fit for him, she had also Shirley attempting to shoot her in order to protect Lelouch from Villetta's machinations. Thankfully, as Villetta was about to attack her, Bumblebee's timely intervention had saved Shirley's life as he had managed to shoot Villetta with his Energon blaster. (R1, Chap 17 to chap 18)
Thankfully, she had managed to survive Bumblebee's attack albeit she had developed scars on her back as a result. However, due to the trauma of Bumblebee's attack, she had developed amnesia as a result which means she doesn't remember her discovery of Zero's true identity. After she had managed to recover when she was temporarily staying at the Ark's medical center, Kaname Ohgi had volunteered to take care of the now amnesiac former Pureblood so that he could supervise her just in case she had managed to regain all of her original memories which Zero had accepted due to Kaname being less likely to do something to her out of spite compared to Shinichiro Tamaki. As time goes on, Villetta who is now going under the name that Kaname had gave her, Chigusa, had begun to develop romantic feelings towards Kaname and empathy towards the "Elevens" that she had once looked down on to the point where she doesn't mind being an "Eleven". (R1, Chap 19 to Chap 31)
Eventually, Kaname had told her about the conflict between the Autobots and the Decepticons as well as what happened to their homeworld, Cybertron, and Villetta's past. Due to her developing remorse towards everything she had done before she had lost her memories as well as her developing guilt due to witnessing the Special Administrative Zone Massacre via herself assuming that her original self would partake in something like that, Villetta had made the decision of joining the Autobot/Black Knight Alliance with Kaname vouching for her as well as helping her change for the better. (R1, Chap 32)
Eventually, when Lelouch was brought to the Ark's medbay after he was affected by Megatron's Dark Geass of Absolute Terror, Chigusa was one of many who had witnessed the subsequent revelation that Lelouch himself is the true identity of Zero. (R1, Chap 36)
Not long after the events of R1: Rebellion but before the events of R2: Revolution had started, Villetta herself had managed to regain all of her original memories albeit she had retained the kind personality that she had developed when she was Chigusa as well as regaining her resolve and fighting abilities as a Britannian soldier. Neverthless, due to what she had undergone when she was originally amnesiac, Villetta had chose to go by the name "Chigusa" as she is now a loyal member of the Autobot/Black Knight Alliance.
Gilbert GP Guilford[]
The personal knight of the 2nd princess of the Britannian Imperial Family, Cornelia li Britannia, Gilbert is a member of Cornelia's honor guard. Even though he is a member of the Britannian Military, he has made it clear that his loyalty is strictly to Cornelia only rather than to Britannian as a whole and he would do anything for her even if it goes against Britannia's plans. After he was defeated by the Decepticons during the Black Rebellion while he had attempted to cover Optimus Prime's, Kyoshiro Tohdoh's and the 4 Holy Swords' retreat, he was captured by them and forced to endure a life as one of the Decepticons' slaves.
For 6 months since his defeat, he was one of many people who had been forced to work in Mount Fuji's Energon Mine. Thankfully, he was rescued alongside any and all of the aforementioned slaves when the Autobot/Black Knight Alliance had resurfaced in order to destroy Mount Fuji and announce their return to the world itself. As he was recovering in the Ark, Princess Cornelia had greeted him and told him about the revelation that Lelouch vi Britannia is actually alive as well as Lelouch himself being Zero's true identity. Even after Cornelia had explained everything to him, Gilbert had still maintained his loyalty to her as he had sworn an oath to be by her side beforehand. Thus, he had decided to join the Autobot/Black Knight Alliance as well. (R2, Chap 2)
Elita-One[]
Originally, she was a Cybertronian who had worked as a laborer due to herself being a member of Cybertron's lower class as well as going by her original name, Ariel. During those days, she became friends with Optimus Prime's original identity, Orion Pax, who had came to her so that he could gain an idea on how to improve Cybertron for the better. She had became friends with Orion, Ratchet, Ultra Magnus, Alpha Trion as well as many other Cybertronians who also wanted to change Cybertronian society for the better, even Megatron with Ariel herself developing romantic feelings towards Orion. Eventually, before the Great War had started, Ariel had changed her name to her current name albeit Megatron would call her by her original name in order to shame her. However, once the Great War had progressed back on Cybertron, whatever plans that both Elita-One and Optimus Prime had for each other with regards to their relationship, those plans had been rendered kaput once Cybertron had been destroyed by Megatron's actions albeit she still cares about Optimus and considers him as a really good friend of hers.
Based on her interactions with Lelouch vi Britannia, Kallen Kozuki and Nunnally vi Britannia in "R2: Revolution, Chapter 4: Spark of Darkness", it is implied that she had knew about Zero's identity as Lelouch vi Britannia after she had arrived on Earth and had joined the Autobot/Black Knight Alliance before the events of R2: Revolution had started. (R2, Chap 4)
Leila Breisgau/Malcal, Akito Hyuga, Anna Clement and Claus Warwick[]
When Zero along with several members of the Autobot/Black Knight Alliance had met with Leila Malcal, Akito Hyuga, Anna Clement and Claus Warwick in order for them to discuss with each other about their plans regarding how they should deal with the Decepticons as well as what to do during the aftermath once the war against them was over, Zero had proceeded to reveal his true identity to the aforementioned individuals as part of his attempt to earn their trust. Thanks to Kallen Kozuki vouching for him as well as Zero demonstrating just how much the Autobot/Black Knight Alliance knows about Lelila's true identity thanks to the help of the worldwide anti-Britannian terrorist organization known as Peace Mark, the aforementioned individuals then proceeded to form an alliance between the wZERO unit and the Autobot/Black Knight Alliance in order to defend both Euro-Britannia and Europia United from the Decepticons' machinations. (R2, Chap 7)
Yukiya Naruse[]
Shortly after he and his two friends, Ayano Kosaka and Ryo Sayama, had been taken into the custody of the wZERO unit and the Autobot/Black Knight Alliance, the trio in question had made plans to turn against the two groups so that they could get out of their custody. Yukiya had even planned to act as a suicide bomber in order to help his 2 friends escape even though that's not actually true due to his close bond with both Ayano and Ryo. Fortunately, thanks to the shared suspicions between the members of the wZERO unit and the Autobot/Black Knight Alliance as well as the efforts of the Autobot known as Prowl who had reported the aforementioned trio's plan to them when he had secretly observed them, said trio's plans to escape their custody had been successfully thwarted as well as being convinced by them to stay and fight alongside them.
In Yukiya's case, he was confronted by Akito Hyuga, the Autobot known as Grindcore and Zero himself. As part of his attempt to earn his trust, Zero had revealed his true identity as Lelouch vi Britannia as well as revealing his Geass to Yukiya himself. (R2, Chap 8)
Grindcore and the other Wreckers[]
A jovial Autobot who is a member of the Wreckers, a combat unit that's part of the Autobot/Black Knight Alliance which normally operates outside of the aforementioned organization's chain of command. Not only that, Grindcore has the ability to transform into a monster truck.
Based on his reaction when Zero had revealed his true identity as Lelouch vi Britannia to Yukiya Aruse himself in "R2: Revolution, Chapter 8: To Divide and Unite", it is implied that he had knew about Zero's identity as Lelouch vi Britannia after he had arrived on Earth and had joined the Autobot/Black Knight Alliance before the events of R2: Revolution had started. (R2, Chap 9)
Not only that, given how close the Autobot known as Bulkhead is to the Autobot known as Wheeljack as both Autobots are part of the Wreckers, one can safely assume that all of the Wreckers had known about Zero's true identity as Lelouch vi Britannia due to Bulkhead being most likely to not be willing to keep any secrets from his fellow Wreckers.
Ayano Kosaka, Ryo Sayama, Gino Weinberg and Orpheus Zevon[]
The aforementioned individuals don't show any kind of surprise when Yukiya himself had announced Zero's arrival when Lelouch had approached them with Akito Hyuga and C.C. indicates that the aforementioned individuals had already been told of Zero's true identity as Lelouch vi Britannia sometime between "R2: Revolution, Chapter 8: To Divide and Unite" and "R2: Revolution, Chapter 9: Leave of Absence".
Marrybell mel Britannia[]
A Princess of the Holy Britannian Empire as well as being the founder and leader of the anti-terrorism organization called the Glinda Knights.
During the Decepticons' worldwide conquest of the Holy Britannian Empire's numerous areas, Marrybell as well as several members of the Glinda Knights had managed to flee from the Decepticons in the Grandberry as they are conquering Area 24. Thus, Marrybell is the only known member of the Britannian Imperial Family who is still alive and free from the Decepticons' clutches. However, she was eventually brainwashed by Shin Hyuga Shaing via his Geass when the current leader of the Holy Order of Michael himself had betrayed Euro-Britannia and joined the Decepticons.
Under Shin's control, she had attacked Zero, Cera, Bumblebee, Akito and Orpheus when they as well as their fellow allies had entered a Euro-Britannian vessel called the Gallia Grande as part of Shin's trap. However, during the fight, Cera had managed to neutralize the Geass commands that had been placed onto both Marrybell and Akito with some help from Orpheus Zevon who had used his Geass to disguise himself as his late girlfriend who is also Marrybell's late younger sister, Princess Euliya mel Britannia in order to snap Marrybell out of Shin's Geass command.
However, even after she was finally freed, she had still retained her desire to rid the world of terrorism. Thus, she still wanted to kill Zero for bringing chaos onto the world. Thankfully, Zero had managed to convince Marybell to spare him as he then revealed his true identity as her thought to be deceased half-brother, Lelouch vi Britannia along with trying to appeal her by bringing up the fact that all of her memories have been fully restored as well as the survival of Nunnally vi Britannia, Cornelia li Britannia and Euphemia li Britannia. As a result, Marrybell had accepted Lelouch's offer of becoming a member of the Autobot/Black Knight Alliance. (R2, Chap 11)
Shin Hyuga Shaing, Jean/Jeanette Rowe, Steeljaw and Sky-Byte[]
Shin Hyuga Shaing is the current leader of Holy Order of Michael after he had used his Geass to command his previous superior, Michele Manfredi, to commit suicide. Despite his seemingly honorable and kind demeanor, certain individuals had managed to notice his true character which is that of a twisted and power hungry madman. The Decepticon known as Steeljaw was one of those people with the Decepticon himself befriending Shin as well as teaching him how to use his Geass in a way that could benefit the Decepticons and Shin himself which had, in turn, formed a partnership between Shin Hyuga Shaing and Steeljaw.
Not only that, both Steeljaw and Shin Hyuga Shaing are intelligent enough to figure out Zero's true identity as the thought to be deceased 11th prince of the Holy Britannian Empire, Lelouch vi Britannia, as well as casually outing his true identity along with Nunnally vi Britannia's true identity.
Plus, both Sky-Byte and Jean Rowe were there when both Steeljaw and Shin Hyuga Shaing had outed their identities. Thus, they now know who Zero is as well. (R2, Chap 12)
The Caretaker of Spacetime and Vector Prime[]
The Caretaker of Spacetime is the collective consciousness of the Universe who acts as a seer that watches the world's balance from within whereas Vector Prime is the second Prime to be created by Primus who acts as Primus' appointed guardian of space and time. It was implied that the both of them were aware of Lelouch vi Britannia's actions as Zero throughout the entire story itself. (R2, Chap 13)
Empress Tianzi and Li Xingke[]
Empress Tianzi is the current Empress of the Chinese Federation who had been used by the High Eunuchs as a tool for their own benefit whereas Li Xingke is a soldier who is a member of the Chinese Military as well as being devoted to Tianzi herself due to an incident in the past when Tianzi had vouched for Li's life to be spared after he was caught giving medicine to a prisoner. Li Xingke had became an informant of the Autobot/Black Knight Alliance sometime before "R1: Rebellion, Chapter 36: Till All Are One" so that they could help him and his comrades re-establish the emperor's throne as a proper source of authority in the Chinese Federation.
Optimus Prime as well as several members of the Autobot/Black Knight Alliance had managed to protect Tianzi's life from the Decepticons' and the High Eunuchs' machinations as well as depose the High Eunuchs themselves from their undeserving positions as the true leaders of the Chinese Federation. Not only that, after the Chinese Federation had been liberated with all of Li Xingke's comrades and Empress Tianzi's followers becoming part of the group itself, Zero had willingly exposed his identity as Lelouch vi Britannia to Empress Tianzi herself so that he could gain her trust which he did.
Not only that, Li Xingke had also witnessed the aforementioned revelation taking place but, in spite of himself feeling shocked, Li himself had quickly formed his feelings of respect towards Lelouch for not only revealing his true identity to the Empress but also forming a compassionate and caring bond with her. (R2, Chap 16)
Grimlock[]
Leader of the Dinobots as well as being one of the most powerful Autobots alive. After he had destroyed Shockwave's Spacebridge during the Great Exodus back on Cybertron, Grimlock got caught up in the resultant explosion and was sent to Earth where he had remained in stasis in the Sahara Desert for many years once he had crash landed on said planet before he was eventually discovered by Shockwave.
Optimus Prime as well as several of his fellow members of the Autobot/Black Knight Alliance had detected his presence during their mission of liberating the Chinese Federation from the Decepticons' and High Eunuchs' clutches. Even though they had managed to defeat Shockwave and his cohorts as well as freeing Grimlock from his current situation, the Dinobot himself was still sufferring from his uncontrollable bouts of rage which were a result of Shockwave's experimentation on him back on Cybertron. Thankfully, Optimus Prime had used his Prime Geass of Absolute Conviction to calm him down before proceeding to tell him everything that he needs to know as well as pleading to Grimlock that he needs to help the Autobot/Black Knight Alliance which he had agreed to do so under a few conditions that Grimlock had set for Optimus Prime to abide to.
After Lelouch had returned from his mission of forming an alliance between the Autobot/Black Knight Alliance with both Euro-Britannia and Europia United, he had revealed his himself to Grimlock. While Grimlock doesn't think that Lelouch deserves his respect, Lelouch himself claims that sooner or later Grimlock will see whether he deserves the Dinobot's respect or not. (R2, Chap 16)
Jeremiah Gottwald[]
Once a member of the late Marianne vi Britannia's guard, his failure to prevent Marianne's assassination had always haunted him since then. By the time of R1: Rebellion, he has become the leader of the Britannian Purist Faction, a political and military faction of the Holy Britannian Empire that opposes the system of honorary citizenship with the members of said group believing that Britannian society and the empire's military should not be "polluted" by the presence of foreigners.
However, ever since the night of Zero's and the Autobots' debut where Zero had used his Geass to command Jeremiah to spare his life and the lives of the Autobots as well as giving Suzaku Kururugi to their custody, Jeremiah had been disgraced as he was mocked and humiliated by most of his fellow members of the Purist Faction. Not helped by the fact that Zero had called him "Orange" in order to frame him as an anti-Britannian spy. Since then, he had been obssessed with wanting to kill Zero and the Autobots for humiliating him. To the point of disobeying orders from his superiors so that he could make use of any presented opportunity to kill them and regain his rightful position in the Britannian Military.
Unfortunately, for him, his impulsiveness and low patience had caused him to be defeated by Kallen Kozuki, Arcee and Cliffjumper during the Battle of Narita. While everyone assumes that he is dead, he had actually managed to survive albeit barely as he is now delusional and being unable to walk properly before he was quickly recovered by the 2 Decepticons known as Soundwave and Shockwave upon Shockwave's arrival on planet Earth. Since then, he was subjected to Shockwave's experiments where he was turned into a powerful soldier thanks to Shockwave's Cybertronian enhancements on his body at the cost of being turned into a slave of the Decepticons themselves.
Fortunately, many months later after the Holy Britannian Empire had been all but wiped out, a scientist who is forced by the Decepticons to work for them had managed to help Jeremiah regain his free will as part of said scientist's plan of taking down the Geass Order and freeing himself from the Decepticons' sinister hold on him. This scientist was one of the scientists of Code R, a research them that was formed by the Holy Britannian Empire's late 3rd prince, Clovis la Britannia, as well as being the father of Shirley Fenette, Joseph Fenette.
Thanks to Joseph's actions, Jeremiah had secretly regained his free will. He had came across Nunnally vi Britannia, Shirley Fenette, Milly Ashford, Rivalz Cardemonde, Sayoko Shinozaki, Bumblebee, Arcee and Smokescreen when they had traveled to Paris' catacombs in order to recover one of the Iacon Relics that had been located there. Upon noticing Nunnally's presence among the aforementioned group, she had told him everything such as Lelouch vi Britannia being alive as well as Lelouch himself being the true identity of Zero. In return, Jeremiah had tearfully confessed to him about his great failure of protecting Marianne vi Britannia herself. As he had declared his unwavering loyalty to Marianne, Jeremiah had destroyed his power source which contained a beacon that would allow Shockwave to track him down but, fortunately, Joseph had secretly installed a back-up power source that's not connected to the Decepticon network before he then proceeds to help Nunnally and her friends in dealing with the 2 Decepticons that they were fighting against as well as securing the Iacon Relic in question.
Even though his prior actions had gave most of the Autobot/Black Knight Alliance's members a bad impression of him, Jeremiah had pleaded to them to give him a chance to prove his loyalty to the alliance itself. He had swore his loyalty to not only Lelouch and Optimus Prime but to the entirety of the Autobot/Black Knight Alliance as a whole. In fact, he now accepts the title "Knight of Orange" as a symbol of his loyalty to the alliance as well as the nickname "Orange" as a compliment. (R2, Chap 18 and Chap 27)
Anya Alstreim/Marianne vi Britannia[]
One of the Knights of the Round, Anya Alstreim was a 15 year old girl who was the youngest member of said group with herself going by the title, Knight of Six. However, in spite of her skills and abilities as a Knightmare Frame pilot, Anya suffers from a mysterious mental condition that forces her to undergo recurring memory lapses where she doesn't remember anything about her life. As a result, she has a tendency to second-guess her memories as well as having to update a blog that she had created in order to keep track of what she had done in the past. Little did she know, Anya actually carries a dark secret. A secret that not even she herself was initially aware of.
Marianne vi Britannia was one of Charles zi Britannia's consorts as well as being a former member of the Knights of the Round with herself holding the title of "Knight of Six". She was also the biological mother of both Lelouch vi Britannia and Nunnally vi Britannia. Little did anyone knew, Marianne was one of the 4 architects of the original Ragnarok Connection with the other 3 architects being her husband, Charles, her brother in law, V.V., and C.C. However, several years ago before the start of R1: Rebellion, Marianne was lured to a trap by V.V. as part of his attempt to murder her due to his feelings of jealousy towards Marianne's and Charles' relationship with each other. Fortunately, for her, C.C. had gave Marianne a Geass beforehand which had granted her the ability to transfer her spirit and Geass to another person. Thus, when she was mortally wounded, Marianne had used her Geass on a person who just happened to be nearby as well as having witnessed her death at the hands of V.V.. Anya Alstreim, a young girl who was staying at Pendragon's Aries Villa as an apprentice in order to learn proper etiquette.
Using her Geass, Marianne had transferred her spirit into Anya's mind. During the aftermath, Charles had used his own Geass to alter the memories of those who would recognize Anya herself due to said young girl staying at Aries Villa, at the time. so that they wouldn't be able to recognize her. Since then, Marianne's spirit had been hiding inside Anya's body with her presence being the cause of Anya's mysterious mental condition.
From time to time, Marianne would communicate with C.C. by using her Geass before C.C. had eventually decided to render the contract between C.C. and Marianne themselves null and void which had finally removed Marianne's ability to communicate with C.C. as well as being able to communicate with Charles zi Britannia without V.V. knowing. In fact, it was implied that she knows about Lelouch's activites as Zero as well as the true statuses of both Lelouch and Nunnally themselves but she had not done anything yet due to both herself and Charles not wanting to either the Autobots or the Decepticons to become aware of their plans regarding the Ragnarok Connection.
Ever since the Decepticons had destroyed Pendragon and killed Charles, Marianne herself had swore revenge afainst Megatron for destroying the dream that both Marianne and Charles had shared with each other. Not only that, Marianne had also hated Optimus Prime just as much as she hates Megatron due to herself viewing Optimus himself as playing a part in helping Megatron discover Charles' and her plans regarding the Ragnarok Connection as well as taking both of her children, Lelouch and Nunnally, away from her.
However, during the Battle for the Ark, Anya and subsequently Marianne herself was exposed to Optimus Prime's Prime Geass of Absolute Conviction which had enabled Anya to discover Marianne's spirit that was living inside of her body. As a result, Anya Alstreim had started to feel emotions that she had not felt in a long time while Marianne had started to feel guilt and regret over her actions. Thus, Marianne had set up a link between herself and Anya so that they could communicate with each other which had resulted in Anya learning all of Marianne's secrets as well as both Anya and Marianne themselves teaming up with a select few individuals who are working for the Decepticons such as Joseph Fenette in order to defeat Megatron and destroy the Geass Order in order to take the Decepticons down.
After the Geass Order has been destroyed as well as Megatron himself being initially defeated by being sent to what's considered as a tight and inescapable prison, Marianne then proceeds to reveal herself to Lelouch, Nunnally, Sayoko Shinozaki, Jeremiah Gottwald and Optimus. Once she had proved to everyone in attendance that her current status is not a trap that's made by the Decepticon known as Shockwave, Marianne had told everyone in attendance the entirety of her true story while keeping the fact that she herself is also one of the original Ragnarok Connection's 4 architects a secret. Thus, both Lelouch and Nunnally as well as Jeremiah had welcomed Marianne back along with accepting both her and Anya as new members of the Autobot/Black Knight Alliance albeit Anya was pissed off at Marianne for choosing to delay herself in telling both Lelouch and Nunnally the truth.
