Given that the characters from Code Geass have been translated into a different universe, obviously the changes to these characters need to be taken into account. There are also several O Cs that pop in every now and again that play minor, but significant, roles. Even the Fairy Tail cast has some tropes applying to them here that don't apply in canon.
Characters are listed in alphabetical order until a better sorting algorithm has been developed. At present only the Code Geass characters are listed.
Anya AlstriemA rock dragonslayer. She was found all alone by Gino sleeping in the dirt. He took her in and cleaned her up and she developed an attachment towards him. They joined Knightmare Frame in X781.
Carine CelestineA member of Knightmare Frame that can manipulate anything with chlorophyll in it. She seems to get along well with Guinevere
CCHer full name is Cynthia Caroline. CC is her nickname. She is one of the four founders of Knightmare Frame along with Marianne, Lelouch, Cornelia and Nunnally. Her magic is called Geass, a powerful variation of hex magic with seemingly no limit to what it can do. Both her eyes contain the special power. She has lived with Lelouch all his life according to what he said in chapter 2 and according to chapter 4 is lifelong friends with Marianne.
Cecile CroomyA healer who is part of Suzaku’s Team Lancelot.
Charles VermillionLittle is known about this incarnation of Lelouch’s father at present, which is odd considering the large role he played in canon. Going by the quote at the end of chapter 15 and the fact that he’s a former member of Fairy Tail it doesn’t seem like Charles is anything close to the Charles we all remember. Then again, neither is Marianne. He also died leaving his entire fortune to Marianne telling her to live out her dream and make a guild to take in mages with nowhere else to go.
Clovis LahruneA member of Knightmare Frame. Like Schneizel he is a lady’s man, but with a small success rate.
Cornelia HeurasseinA mage ten years Lelouch, Kallen and Suzaku’s senior. Her magic is called Trace: The Gunner. She can create any type of gun she wishes. She has used this power to create weapons that Spawn, Halo, and many other shooters would be envious to get their hands on. She is one of Knightmare Frame’s S-class mages.
Cornelia used to be a young noblewoman on an island, not allowed to leave the castle she lived in, but her rebellious nature she launched a chain of events that wound up with her being framed for the murder of her older sister’s fiancée, which ultimately ended up with said elder sister, dying. Cornelia escaped the island with her life along with Nonette and Euphemia. After several years of toughing it out on the streets, Marianne found them in the cold snow and invited them to join Knightmare Frame. They’ve been with the guild ever since.
During her arc, she and the guild go to the island she was born and raised on in order to clear Cornelia’s name of the murder.
Euphemia HeurasseinCornelia’s younger sister and a mage with no combat ability to speak of. Her magic allows her to change the colors of any object to another color. At the young age of four she escaped Sylvas with Cornelia and Nonette and joined Knightmare Frame with them.
Gino WeinbergA dragonslayer of a currently unknown element, but the rest of the guild knows he has it because he shows the symptoms of being one i.e motion sickness. He is a second-generation dragonslayer and therefore doesn’t have the usual angst the rest of them do. However, this is in spite of the fact that when he was done with the program to give him the Lachryma cells that made him one his home village had become a Doomed Hometown. He left the rubble with a rucksack on his back and found Anya two weeks later. They became close and the two of them joined Knightmare Frame in X781.
Guinevere AntoinetteA high-class grade A ‘’bitch’’! Her Establishing Character Moment has her set up as a Vain Sorceress. However, it seems even she has a sob story just like everyone else in the guild going by what Schneizel has said. She seems to get along with Carine just fine though.
Jeremiah GottwaldThe first member to join Knightmare Frame. He refers to Lelouch as “young master” and, of course, has Undying MOTHERFUCKING LOYALTY to Marianne. He used to be a guard for a noblewoman only for the house to be attacked and burned by a dark guild. Marianne met him during the attack on an expedition of hers. She pointed him in the direction of the dark guild. When she came back from her destination she found him in the road hanging on by a thread having given the dark guild what for and asked him to join her and use his Undying Loyalty for her sake. His powers allow him to shapeshift into several different kinds of matter. Lelouch has mentioned Steel, Wood and Concrete and we’ve seen Iron, Marble and Silver.
Kallen KozukiA red haired mage with a magic known as demonic deformity. Her entire right arm is demonic and lets her spit out radiation. She has been kicked out of two guilds and has seen the fall of a third. Knightmare Frame was at the beginning her last hope before she would have amputated her arm, but has since found out she’s considered a member of their family since the moment she put on their tattoo.\\
She obtained her power at the young age of 5 when she and her brother Naoto made a mistake in a summoning that caused Naoto to be dragged into the demon realm and forever cursed Kallen with a deformed arm. Until meeting Mirajane Strauss she was never able to control her power.
Kaname OhgiAn earth mage that is part of the Black Knights
Kaguya SumeragiA member of Knightmare Frame. The AU counterpart of Empress Sumeragi from canon.
Kent SugiyamaA member of the Black Knights.
Kyoshiro TohdohAn S-class mage from Knightmare Frame and a former member of Fighting Spirit. Before being promoted to S-class he was The Ace of The Black Knights. His magic is known as dual blades. The exact nature of it is unknown at present, but he was shown coating two blades with the power of wind.
Lelouch LamperougeA bone dragonslayer and dark mage. Lelouch is the daughter of Marianne Lamperouge, guildmaster of Knightmare Frame. He has a strong sense of justice and believes that there is no tactic too underhanded to make sure the enemy gets what they deserve. His ultimate vision is to use the Black Knights and Zero to allow the council to permit mages to commit murder against those who deserve it and will use lethal force against normal mages anyway.
He is very protective of his little sister Nunnally and has a sibling-like relationship with S-class mage, Cornelia Heurassein, looking up to her like an older sister. He is one of the four founders of Knightmare Frame along with Marianne, CC, and Nunnally. Issues with his father, Charles, lay deep within his memory, but the true nature of that has yet to be revealed. hints have been left though.
Li XingkeAn S-class mage from Knightmare Frame. He apparently is well-versed in a whip-style of magic.
Lloyd AsplundAn ex-quip mage that only wears armor and weapons that he himself builds. He and Rakshata share this skill and are ‘’constantly’’ trying to 1up each other. He is part of Suzaku’s Team Lancelot
Marianne LamperougeLelouch and Nunnally’s mother. One of the four founders and also the guildmaster of Knightmare Frame. Marianne is number six of the Ten Wizard Saints. Her magic is a similar type of magic as Erza’s, but Marianne seems to only have legendary armors that she has excavated herself. None of her armors are store bought or mass produced.
Milly AshfordA blonde mage from Seven who came to Fiore to escape an Arranged Marriage. She can shapeshift into different animals, though often has trouble shifting back. She is the leader of Team Ashford which consists of her, Nina, Shirley and Rivalz.
Naomi InoueA sweet, blue haired woman that runs the bar at the guild. She can’t cook. She has the ability to project and create shields. She is a member of the Black Knights. Because her ability is non-aggressive she often pairs up with other mages on missions. However, apparently she is one of the people—aside from the S-class mages—no one should want to anger. Naomi was married to a mage named Takashi, whom she’d known since she was a little girl. He invited her to join his mage guild. She, Takashi and their nakama were later sent out on a mission to promote Takashi to S-class of which Naomi wound up being the only survivor. She went on a Roaring Rampage of Revenge and wound up in prison. Schneizel, at Lelouch's behest, pleaded her case and Inoue, after being invited to join the Black Knights by Lelouch joined them without hesitation.
Nina EinsteinA clairvoyance mage part of team Ashford. Euphemia was her mentor during her trial period so Nina has an attachment to her of sorts. She is a member of Team Ashford
Nonette EnneagramKnightmare Frame’s Ace and also a former guildmaster in her own right. Nonette has the power to stop time, use a giant invisible hand to crush things and summon a plethora of knives for stabbing and throwing in a huge Flechette Storm. Known as the Phantom Walker she is easily Knightmare Frame’s strongest asset excluding its guildmaster. Nonette is only a year younger than Marianne and is best friends with fellow S-class mage, Cornelia Heurassein and their friendship goes way back. Nonette is responsible for helping Cornelia off the island of Sylvas as a teenager and the two have known each other for over twelve years. She was also once considered for the Wizard Saints.
Nunnally LamperougeLelouch’s younger sister, cute as a button that only wants to pet little puppies and is happy living amongst the members of the guild. However, when she is angry or upset she can warp the very fabric of reality to ludicrous potential. Because of this, Lelouch and the others do their best to keep her happy as a clam.
Odysseus ChurchillA member of Knightmare Frame. Lelouch mentions that he is an appraiser.
Rakshata ChawlaAn ex-quip mage who only wears weapons and armor that she herself builds. She and Lloyd Asplund have the same ability and are always trying to 1up each other.
Rivalz CardemondeA glass-make mage. A member of Team Ashford. Attempts to join the Black Knights to impress Milly, but Tamaki beats him down. It’s clear he’s not one of Knightmare Frame’s more powerful fighters.
Schneizel ScifoThe scheming, Magnificent Bastard, backstabbing, chessmaster of the Britannian Royal Family. …oh wait, wrong Schneizel. This one seems to be a pure gentleman with the power to create fantastic illusions like he’s Sosuke Aizen, though Schneizel is a bit more creative in his designs. He is both a master politician and a skilled fighter being one of the S-class mages in Knightmare Frame. He is also one of its "core members" being one of the first few to join in the guild’s early stages. He is polite and cunning and also the Blue Oni to Lelouch’s red. He is a lady’s man and a quite successful one at that.
Shirley FennetteAn atheist water mage. Shirley used to be a regular churchgoer until the day a group of anti-mage fanatic broke into the church during mass and tore the place apart. Shirley’s parents were caught up in it. She prayed every night for her parents’ recovery. The town healer did her best to heal not only Shirley’s parents, but also the other townspeople caught up in things. It turned out though that the healer was a sham and no “miracle of god” came about. Shirley lost faith not only in her religion, but also her own self-worth. Lelouch restored her faith, which is why Shirley now has a crush on him. That and they apparently got stuck in a cave-in during her trial run and had to share body to survive. She is a member of Team Ashford.
Suzaku KururugiLelouch’s childhood friend and one of the first few members of Knightmare Frame. Suzaku’s magic is called kinetics where he charges his own inner magic into energy blasts and physical attacks. In other words, he’s pretty much using magic Ki, given some of his attack names. He and Lelouch may not agree on methods, but both have a strong sense of justice and want to see justice done. It’s just a simple debate on what justice is.
His father, Genbu, was an S-class mage in Fighting Spirit when it was still known as Angel’s Feather.
Tamaki ShinkiroA fire mage who smokes a lot. He is a member of the Black Knights and apparently the bare minimum required to be able to surpass for anyone thinking of joining. Apparently he joined Knightmare Frame because Lelouch helped him settle a gambling debt.
TianziA member of Knightmare Frame. The AU counterpart to Empress Tianzi from the Chinese Federation
