Mobile Suit Gundam: Lelouch of the Rebellion is a crossover fanfiction between Mobile Suit Gundam 00 and Code Geass: Lelouch of the Rebellion. The story has yet to be posted. It possesses two sequels titled Mobile Suit Gundam: Lelouch of the Rebellion R2: Advent of the Geass and Mobile Suit Gundam: Lelouch of the Rebellion Movie: A Wakening of the Trailblazer.
The story is basically a merging of the worlds of 00 and Code Geass, in which Knightmares are a deviation of Mobile Suits are considered slightly weaker, but are still powerful, as Japan fell to Britannia in less than a month. The story focuses on Lelouch vi Britannia, who, in this timeline, is now a member of Celestial Being and goes by the codename Zero Lamperouge. Unlike the canon storyline, there have been several changes, such as Lelouch referring to the Black Knight as the Sword and Shield of both those who do not wield power, and Celestial Being. Another example was that Lelouch, after having captured Cornelia, revealed his identity to her while also raising several dangerous risks to both him and Nunnally, who is now able to see and walk thanks to the medical support Celestial Being offered, the only condition Lelouch made before joining the organization. The storyline involves Zero trying to free all countries and regions under Britannia's control while also simultaneously searching for his mother's killer and establishing the world that Celestial Being seeks: a world where people need only dialogue to come to peace, rather than use force.
The main protagonist of Mobile Suit Gundam: Lelouch of the Rebellion and its sequels. Originally named Lelouch vi Britannia, he is the son of the 98th Emperor of Britannia, as well as to Marianne vi Britannia. He has a younger sister named Nunnally, who, prior to the events of the story, lost the ability to walk and see. He acts as the leader of the group known as the Order of the Black Knights, and unlike his anime incarnation, wants to free all lands that Britannia subjugated rather than destroying the Empire. He also values human life, another contrast to his anime counterpart. At school, he is called Lelouch Lamperouge. Zero pilots the Caesar Gundam, the twin brother of the Exia Gundam. In R2: Advent of the Geass, he pilots the Usurper Gundam. In A Wakening of the Trailblazer, Zero, known to the world as Lelouch vi Britannia, acts as the 99th Emperor of Britannia, and is seen as a pacifistic ruler. Zero also possesses the Geass of Absolute Obedience.
The secondary protagonist of Mobile Suit Gundam: Lelouch of the Rebellion, as well as Zero's best friend. Originally, he was distrustful of Britannians until he met Lelouch and Nunnally when they were exiled. Though apart of the Camelot unit, he later joins the Black Knights, and in turn, becomes a Gundam Meister of Celestial Being, under the codename Lance Kresnik. He acts as the pilot of the Knightmareframe Lancelot and Lancelot Gundam. In R2: Advent of the Geass, he acts as a spy for Celestial Being, operating inside the Knights of the Round as the Knight of Seven, and pilots the King Gundam. In A Wakening of the Trailblazer, Suzaku inherits the role of Zero Lamperouge, and pilots the Heavenly Throne Gundam, the successor to the Usurper Gundam.
A major character in the story. She is half Britannian and half Japanese, coming from a wealthy family that had nearly lost all of its fortunes because of her father's gambling. She and her brother Naoto were members of a Resistence group, with Naoto as the leader. However, sometime prior to the story her brother died, leading Ohgi in charge. It was during an attempt to steal a pathogen weapon containing poison gas that she met Zero Lamperouge and saw the Caesar Gundam in action. She was later confronted about her involvement in Shinjuku, and to her surprise, Zero asked her if she wanted to become a Gundam Meister. After the establishment of the Black Knights, she is made a member of Celestial Being, and operates under the codename Serene Haze. She pilots the Knightmareframe Guren Mk.II, and the Heater Gundam. In R2: Advent of the Geass, Kallen acts as the pseudo leader for the Black Knights in Zero's absence, and pilots the Queen Gundam.
The third protagonist of Mobile Suit Gundam: Lelouch of the Rebellion, and the son of both the 89th Emperor of Britannia and an unnamed member of the Kururugi family. He is found at the front of Ashford Academy, discovered by Milly and Zero. He is suffering from amnesia, but is was revealed that he possesses the Geass of Absolute Obedience, like Zero. He supports Suzaku's ideals that Britannia can be changed from within, and also desires a world where people need only words to understand each other. According to C.C., she met him long ago, but she was not the one who granted him Geass. Like Suzaku, he defects from the Britannian military and becomes a Gundam Meister, becoming the pilot of the Knightmareframes Lancelot Club, Gekka Pre-Production Test Type, and the Thunder-God Gundam. In R2: Advent of the Geass, he operates under the codename Blitz Runner, and pilots the Palace Imperium Gundam. In A Wakening of the Trailblazer, Zero considered Rai taking up the mantle, but instead chose Suzaku, and named Rai the Knight of Zero.
Lucian vi BritanniaEdit
A member of the Britannian military under the alias Lucian Lamperouge, and younger brother to Zero, thus making him the 12th prince of Britannia. He is the primary antagonist of R2: Advent of the Geass, and co-conspirator of V.V. He is completely identical to Zero, except his eyes are dark red, and his hair partially hides his right eye. He seems to bear a deep hatred for Zero, claiming him to be the reason he "suffered". His position as prince was never made public, the reason stated being that his father deemed him "weak" and discarded him like trash. He blames Zero for this, and swears that he will make him suffer. Like Rai and Zero, he also bears a Geass, however it was not one that grants Absolute Obedience. Rather, V.V. refers to it as the Geass of Absolute Death, as any who looks him in the eye will be "sentenced to Death".
Chief Engineer of the Special Corp unit Camelot, and also the one who designed the Lancelot Knightmare. In his youth, he was a dear fried to both Rakshata Chawla and Ian Vashti, however the latter was presumed dead during a test experiment. Lloyd seems to have an obsession of making the Lancelot the ultimate Knightmare, and wished to know the secrets behind the GN-Drive. Upon learning from Zero that it was Ian who designed the Gundams, and that he would personally outfit the Lancelot with a Solar Reactor, Lloyd and the rest of the Camelot unit joined Celestial Being.
The supposed younger brother of Zero in the events of R2: Advent of the Geass. After Nunnally was captured with her whereabouts unknown, Zero came up with a plan that would allow Celestial Being to search for Setsuna, who had gone missing after his encounter with Graham Aker, and also grant them inside information for the group with Suzaku acting as an inside man, as the capture of Zero would allow him a position in the Knights of the Round. Rolo was tasked to watch Zero on the chance that he would regain his memories, however after time passed, he grew fond of Zero's brotherly affection, even after Zero regained his memories. It was after Zero once again declared that he would challenge Britannia that Rolo became a member of the Black Knights, piloting the Vincent Knightmareframe. In A Wakening of the Trailblazer, Rolo acts as the Viceroy of the Special Administrative Zone of America.
Nunnally vi BritanniaEdit
The younger sister of Zero and Lucian vi Britannia. As children, both she and her brother were fond of her mother, however everything changed when Marianne vi Britannia was killed right before her eyes by V.V. out of jealousy. Charles, fearing for her safety from his brother, used his Geass to make her think that she was blind, though everyone else believed it was mental trauma. To make sure that neither Zero nor her were targeted by V.V., he made the excuse that they were exiled and would be sent of to Japan as mere bargaining chips in the war for Sakuradite. However, two years prior to the story, Zero was offered a chance to join Celestial Being, however he stated that he would join if they gave Nunnally her legs and eyes back. She is aware of her brother's role, and asks him to be safe. In R2: Advent of the Geass, she acts as the new Viceroy, with her guardian being her older brother Schneizel, another means of protection from V.V. by her father. In A Wakening of the Trailblazer, she acts as sub-Viceroy alongside Euphemia in the Special Administrative Zone of Japan.
Cornelia li BritanniaEdit
The third princess of Britannia, and older half-sister to Zero, Nunnally, and Euphemia. She is widely renown as the "Goddess of Victory" and idolized Marianne vi Britanna, Zero and Nunnally's mother, who in her youth was a member of the Knights of the Round, and was called "Marianne the Flash". In the events of R1, she acted as the Viceroy of Area 11, and aided Zero in repelling the Earth Sphere Federation forces. In R2: Advent of the Geass, she acts as a member of the Black Knights, who's goal is now to defeat the A-Laws alongside Celestial Being and Kaatheron.
Euphemia li BritanniaEdit
The sub-Viceroy of Area 11, later called the Special Administrative Zone of Japan. Like Nunnally, she is horrified by the idea of fighting, and searches for a more peaceful approach. She admires Zero, seeing him as a figure who values human life, and cares for his allies. She even thought him to be her brother Lelouch, who supposedly died in the bombing alongside his sister. In R2: Advent of the Geass, she reprises her role, but acts as financial benefactor of the Black Knights alongside the Chinese Federation. In A Wakening of the Trailblazer, she is aided by Nunnally, who also acts as sub-Viceroy for the SAZ of Japan.
