Season 1EditLelouch makes his first appearance in the beginning of the first episode of the series, as a child, along with Suzaku Kururugi watching the Britannian Military entering Japan, with the figure of C.C. apparently watching them. After the invasion of Japan, Lelouch vows to obliterate Britannia. He is later introduced to be a student of Ashford Academy where he is a member of its Student Council. He is a brilliant thinker who is quite talented at chess, he lives with his younger sister, Nunnally, and their maid, Sayoko, in the Student Council building of Ashford Academy, where they are looked after by the Ashford Family.
Lelouch and his friend Rivalz enter a room where a chess match was being played, with Lelouch claiming he can turn the situation on the chess table in under 9 minutes. He starts his game by moving the King. He effortlessly crushes him in a short period of time (8 minutes, 40 seconds), while the noble gapes at his own defeat. Rivalz compliments Lelouch on his victory, and is happy that the ego of the nobles will force them to pay, which he notes also make them loose. As they walk out of the casino, they are interrupted by Clovis' "heart-breaking" speech which turns out to be an act. On the road, Rivalz accidentally cuts the way of the terrorists, resulting in their vehicle's crash. People gather, but to Lelouch's disgust, they are more interested in placing the blame and gawking over the incident than helping, prompting him to go and assess the situation. As he inspects the crash, he hears a voice, but is then thrown in the back of the truck, as Nagata, one of the hijackers, puts it in reverse for an attempted getaway. However, Lelouch is soon swept into the conflict between the Holy Britannian Empire and the pockets of resistance which oppose it when he accidentally boards a truck being used by Japanese Resistance operatives. To Lelouch's horror, he realizes that he is trapped in a terrorist getaway. Suzaku, who Lelouch had not met for seven years, finds the vehicle and confronts Lelouch, who he mistakes as a terrorist. Nagata opens the capsule, to which Suzaku quickly puts his own gas mask on Lelouch's face. The capsule opens, instead of gas, as Suzaku expected, a restrained C.C. appears. Before they can get answers, Suzaku's superiors comes and tells him not to question his briefing, and to shoot the "terrorist", Lelouch. When he refuses, he is promptly shot in the back. Lelouch and C.C. takes the opportunity to escape. Just as they seem to have evaded detection, Lelouch's phone rings, giving him away. As they are about to kill him, C.C. jumps in front and is shot in the forehead. A desperate Lelouch now thinks of his impending death, his last thought being of Nunnally. He is grabbed by the hand by C.C., who proposes a contract which would allow him to live and endow him with Geass, the power of kings. He accepts, and stands up reinvigorated, and uses his power to make his pursuers kill themselves. He then retroactively contemplates this moment, noting his life is a lie, but that he accepts it as long as he has the power from it.
Following his actions, Villetta Nu appears in her Sutherland and Lelouch decides to take it and uses his Geass on her as well. After making use of his new-found power, he attempts to crush the rest of the Britannian Military that are wiping out the Elevens in the Shinjuku Ghetto. He uses Ohgi's Resistance Group and gives them orders in eliminating the Britannian Soldiers. He initially gains the upper hand, forcing Viceroy Clovis la Britannia to allow the release of an experimental Knightmare Frame by the Special Envoys, named the Lancelot, which is piloted by Suzaku Kururugi. Suzaku defeats most of the rebel's forces and eventually finds Lelouch's Sutherland inside of a building. Unable to defend himself against Suzaku's attacks, Kallen appears in her Glasgow to buy him enough time to escape, stating that she is returning the favour for helping her. Just as the Britannian Army corners the terrorists, Clovis orders an immediate cease-fire under coercion by Lelouch. Lelouch confronts Clovis at gunpoint about the murder of his mother, Marianne vi Britannia, before killing him.When he returns to Ashford Academy, he discovers that Kallen Stadtfeld, one of the terrorists he helped in Shinjuku Ghetto, attends the same school. The limitations to his power are also revealed to him when he attempts to question her and unsuccessfully erase her memory. Both him and Kallen attempt to gain information from each other, but he creates a cunning deception, through Sayoko, to ease her suspicions of his identity. When the death of Prince Clovis is announced in the media, it is Suzaku who is accused of the murder.
After finding out Suzaku is being accused of murdering Clovis, he assumes the mantle of Zero and reveals himself, in a disguise, to Ohgi's Resistance Group. He convinces them that he will show his power by rescuing Kururugi. During the scheduled public run of Suzaku heading to the courts, Zero appears on top of Clovis' royal transport that was made by Kallen and Ohgi. Debuting to the whole entire whole as Zero, he reveals the capsule that supposedly held poison gas. In exchange for the capsule he wanted Kururugi, but Jeremiah remains steadfast stating that he can not give him up as he murdered Clovis. Lelouch refutes stating that he was the one who killed Clovis. Knowing that Jeremiah would not cooperate, he uses the codeword "Orange" to instill doubt in the Purist Faction and Britannian Military as some sort of bribe or plan in cooperating with Zero. Using this to his advantage, he uses his Geass on Jeremiah to allow them to escape.
To Lelouch's surprise, C.C., the girl who gave him Geass, shows up alive in his residence. He discovers that she is immortal and learns more about his Geass ability.
Arthur, a stray cat slips into the Lamperouge residence on campus and takes off with Lelouch's Zero mask. Milly announced that the one who would catch the cat would get a kiss from any member of the Student Council. A massive, comedic chase throughout the school grounds involving the entire student body follows. Suzaku and Lelouch were the ones that got the cat and got a kiss on the cheek from Nunnally. The student council adopts Arthur and builds a cat house in the council room. Lelouch along with the rest of the student body watches Prince Clovis' funeral on live. During the funeral, the Emperor of Britannia, his father, makes a speech on the virtues of inequality and the social battle for evolution and betterment while Lelouch shows an expression of dislikeness.
Unknown to Lelouch, Cornelia had set a trap for Zero at the Saitama Ghetto by simulating the conditions in Shinjuku Ghetto. Despite C.C.'s warnings, Lelouch takes the bait and goes to the aid of the Saitama resistance. His plan falls apart from a combination of Cornelia's superior tactics and the resistance cell's dissimilar motivations. Lelouch is cornered and nearly discovered, but C.C. dons his Zero costume and distracts the Britannian Army, allowing him to escape. Lelouch blames his defeat on the undisciplined rebels and resolves to build something better than a mere resistance unit, first an army, then "people," and finally a nation.He later forms The Order of the Black Knights during the Japanese Liberation Front Hotel Incident after rescuing the hostages. He leads the Black Knights becoming a revolutionary and gains popular support amongst the Elevens.
The turning point in his rebellion comes when Euphemia li Britannia declares the region under Mt. Fuji, the Special Administrative Zone of Japan, giving the Japanese people their name and country back, albeit in a much smaller area. This effectively destroys any possibility of the Black Knights' rebellion; acceptance would render them powerless and refusal would make them pariahs. Lelouch confronts her at the opening ceremony and tries to have her shoot him, hoping to make himself a martyr. When she says she plans to give up her title, he surrenders and agrees to work with her. However, at this moment his Geass permanently activates, and an offhand comment about ordering her to kill the Japanese forces her to do just that. Lelouch is forced to kill Euphemia to end the ensuing massacre, but in doing so becomes a hero of the people. Using this new-found support, Lelouch announces the creation of the United States of Japan and is able to lead an attack on the Tokyo Settlement. The attack goes well at first, but when Lelouch learns that Nunnally was kidnapped, he abandons the battle, leaving his forces helpless against the much better organized Britannian forces.
On his way to rescue Nunnally, he is intercepted by Jeremiah who is piloting the Siegfried, but is able to lose him after an ensuing battle. Lelouch and C.C. make their way to Kamine Island to search for Nunnally, but Jeremiah appears once more. Being unable to defeat him as the Gawain has taken its toll in the many battles it has participated in, C.C. decides to sacrifice herself and drops Lelouch off.
Using the Gawain's slash harkens and damaging the Siegfried's float system, she drags Jeremiah down to the bottom of the ocean. Afterwards, Lelouch is confronted by Suzaku Kururugi. Kallen appears as well and Suzaku reveals to her that Zero's true identity is Lelouch. Lelouch attempts to broker a truce, but Suzaku is distraught over the death of Euphemia and refuses to listen. An angered Lelouch draws his pistol and both Lelouch and Suzaku attempt to shoot one another. A single gunshot is heard as the screen fades to black at the end of the first season.
One year later, Lelouch is once again a student at Ashford Academy. He has had his memories rewritten by Charles zi Britannia, revealed to possess a Geass power of his own, erasing his memory of him being a prince, being Zero, and that he has a younger brother named Rolo Lamperouge, instead of a sister.
He is seen running away from Villetta Nu who is revealed to be a teacher now in the first episode. He is able to leave Ashford Academy with Rolo to go gamble at Babel Tower. It is here where Kallen and the remnants of the Black Knights attempt to retrieve Zero. After being cornered by the OSI, C.C. appears. Lelouch's memories are restored by C.C. and he uses his Geass to kill all of them. Afterwards, Urabe and Kallen appear in their respective Knightmares and he resumes leadership of the Black Knights. Initially, Lelouch makes his base in the Chinese Federation's consulate, using his Geass on the High Eunuch stationed there so they will be welcomed. They are eventually forced to abandon it, however.
When Nunnally is appointed as Viceroy of Area 11, and announces her plans to re-establish the Special Administrative Zone of Japan, Lelouch falls into depression since he would be impeding her wishes by continuing his rebellion. He nearly begins taking Refrain before Kallen stops him. With the help of Kallen and his friends at the Ashford Academy, Lelouch realizes that his mission no longer revolves solely around Nunnally, but concerns the rest of his friends and the Japanese people as well.
Lelouch engineers the legal exile of the Black Knights by getting the Britannians to agree to exile Zero in exchange for bringing one million participants for Nunnally's new Japan. By having them all dress as Zero, he forces Suzaku to exile them and The Black Knights escape to the Chinese Federation, where Lelouch begins forging an alliance with the other world powers to create a force that rivals Britannia. He starts by destabilizing the Chinese Federation, returning control to Empress Tianzi from the High Eunuchs.
During his time in Area 11, Shirley is killed by Rolo after her memories are restored by Jeremiah Gottwald, an assassin for the Geass Directorate. Unable to retaliate against either, as they are now his allies, Lelouch instead wipes out the Directorate, in the process learning of C.C.'s wish to die and that the Emperor has become immortal. C.C. would have had Lelouch kill her and take on her immortality, but instead spares him by placing him inside her memories while the Emperor kills her. Lelouch refuses to let her die unhappy and convinces her to live on, but her memories of her life after gaining Geass are erased during their escape.
Once Lelouch's new alliance, the United Federation of Nations, is formed, their first act is to liberate Japan. To insure Nunnally's safety, Lelouch meets with Suzaku in an attempt to convince him to help. Lelouch takes full responsibility for all that he has done rather than admit the truth, but Suzaku agrees to help since he recognized what Lelouch is doing. Prince Schneizel's troops, having been ordered to follow Suzaku, then move in to arrest Lelouch, convincing him that Suzaku sold him out. Lelouch escapes with the help of Guilford, having used his Geass to make Guilford see him as Princess Cornelia, and begins his attack on Tokyo. Rolo and Sayoko are sent in to retrieve Nunnally and Kallen.
The battle initially goes well, but the hostilities are cut short when Suzaku fires Nina's F.L.E.I.J.A. bomb under the influence of the Geass command Lelouch placed on him. Nunnally is apparently among the dead, which leaves Lelouch heartbroken. This is only made worse when Schneizel appears in order to speak to the core members of the Black Knights. Schneizel is able to convice them to betray Lelouch using recorded evidence from his meeting with Suzaku, revealing his real identity of being Zero and his power of Geass. Kallen meets up with Lelouch to tell him that Ohgi wants him to come to warehouse 9. In the elevator, Kallen expresses to Lelouch her gratitude for Nunnally's help when she was captured.
They then arrive to see that the core members of the Black Knights are betraying him, stating they know his real identity and Geass power. With Lelouch backed into a corner, he reveals his identity and lies that everything he has done was for his entertainment in order to save Kallen from dying with him telling her that she needs to live. As they are about to gun Lelouch down, Rolo appears in the Shinkirō to evacuate him, but dies in the attempt as he overuses his Geass. Lelouch comes to terms with his feelings for Rolo and buries him properly, as the little brother of Lelouch Lamperouge.
Following the betrayal of the Black Knights, Lelouch focuses on defeating the Emperor, Lelouch confronts the Emperor in the Sword of Akasha, where he learns the truth about his mother and Charles' plans. He denies their attempt to create a new world and kills both of Charles and Marianne. One month later he installs himself as the 99th Emperor of Britannia and appoints Suzaku as his Knight of Zero.As Emperor, Lelouch abolishes all the oppressive laws and class systems of Britannia, frees every colony (thereby abolishing the concept of "Numbers"), and puts down all resistance to his goals. However, the seemingly benevolent acts are a smokescreen for his intention to take over the world, which he calls the Zero Requiem. He announces that Britannia intends to join the U.F.N. At the meeting, Lelouch takes the council members hostage after it is revealed that Britannia's large population would give him a majority voting block. This brings him into conflict with Schneizel and the Black Knights, the former bringing his F.L.E.I.J.A.-equipped floating fortress into the battle. The biggest surprise comes when Nunnally is revealed to be alive and declares herself to be his enemy. Though initially reluctant, Lelouch is convinced that he must fight her for the sake of his plan.
Lelouch began to leave when Damocles continues to fire F.L.E.I.J.A. Shortly afterwards, Lelouch saw C.C and says to her that he is worried about her but then Kallen attacks Avalon and is saved thanks to C.C. Using Nina's countermeasure, Lelouch and Suzaku disable the F.L.E.I.J.A. and the two proceed to board the Damocles. He manages to place Schneizel under his control, then goes to confront Nunnally, who has regained her sight. Lelouch uses his Geass on Nunnally to get her to hand over the F.L.E.I.J.A. launch button and takes over Damocles. With no one left capable of opposing him, Lelouch becomes the ruler of the world.
