As the title suggest, this is Oneshot Xover. I have many xover ideas for Code Geass but don't have the effort to make a story so I do oneshot. Might change/update existing chapters! Should warn you there might have Lemons, Incest & other things that are for M Rated.

When the peaceful world of ZeroTopia was attacked by invaders from different world, the residents led by young former emperor must team up with offworlders to get rid of the threat that tries to destroy their home world.

2110 a.t.b.: Ghouls, known as 'the Demons children', are humanitiy's current foe, and natural predator. What happens when one unlikely, tragic protagonist slowly regains the powers and memories of a past life? And more importantly - can he find and reconcile with those whom he'd previously wronged? (Rated M due to gore and language) I don't own Code Geass or Tokyo Ghoul.

A self insert where my friends and I are all the characters in Code Geass. It really is terrible, but hilarious.

Naruto Uzumaki, a smart young man who's family was killed by some unknowns, he turned towards the world of hacking and though it he will find the killer of his family, but what will he do after that? Parings will be Milly and C.C, but if you want me to add someone other then tell me and I will see if I can.

Dans un autre monde, moins futuriste mais étrangement similaire, un jeune homme sans nom se réveille dans un hangar, ses souvenirs effacés... Bientôt il deviendra l'assassin le plus exceptionnel que la terre ait connu...

A long time ago, in a galaxy far far away... The Galactic Empire has fallen, and from the ashes the New Republic rises. Confronted by the threat of squabbling Imperial Warlords the galaxy at large remains ignorant of the external threat which has brought a ghost from the past and his heir to the attention of Grand Admiral Thrawn on an isolated planet called Earth.

After perfectly executing his Zero Requiem, Lelouch is content as he fades away into oblivion. His death is not the end however, as he finds himself reborn in a land where humans manipulate the very elements that govern them. In this world where he is completely unknown, will he find peace or strive to become something greater?

Lelouch vi Britannia. Tom Marvolo Riddle. So similar, and yet so different. When a certain bored Master of Death decides to meddle with history, Lelouch is deaged to ten and pulled into an unknown world upon his death. What happens when the Demon Emperor unintentionally befriends the young Dark Lord? Who is the strange boy with green eyes that follows them around? WW2. Death!Harry

Lelouch finds himself in the world of Remnant after Zero Requiem. However, he finds that the world he's beginning a new life in is just as treacherous as the one he left behind. Can new allies help him triumph over the returning darkness? Or will Lelouch return to his old ways and commit evil to destroy a greater evil?

Who would win, Lelouch or Light? This is my answer.

The Greater Japanese Empire occupies The Holy Britannian Empire.

When Lelouch Vi Britannia died, the collective unconscious owed him a debt. Now it seems it can be repaid. For one who never had time for games, it was ironic Lelouch would find himself trapped in one. But unlike the other ten thousand players of sword art online, he was different. The glitch in the code.

A complete rewrite of rise of a sage! Stranded in this new world, Naruto must do what he can to protect those he care about! Watch as our blond hero fights an Empire that controls more then half of the world in order to bring peace to this new world for his friends and his adopted little sister, wait, what? Rated-M

The multi-verse, endless in in thought and dimensions, some have heros from others arrive, some or born in others...what if in this particular verse, a family breaks through? What if they bring along something extra for the ride? What if...this happened to Code Geass verse? How will things change? How will they stay the same? Read on dear viewer, and see with C's Infinite sight.

Now following from me: the only good thing coming out of watching the Arise movies series. or: How one minor character, interferes with a major character of (nearly) the same name.

After a hard fought battle Danny is thrust a thousand years into the future. The usual happens – dubious characters attempt to enfold Danny into their plans, ominous overshadowing chess games with far too much meaning – but if he has surprised a man who can see all outcomes of time, he'll be sure to throw a wrench in any crazed Fruit-loop scheme he doesn't like. Adopted from...

Sample of a idea I have of a potential scenario for Lelouch as a pirate. Kewell and the Purist Pirates think they have found a perfect ambush target, but in truth they are falling into the trap of a powerful devil fruit user with odd plans. Challenge at the end.

The Demon has awakened. The board is set. But will he play? How will the Wizarding World fare now with a highly-intellectual and cunning former Demon Emperor as their Boy-Who-Lived? Lelouch reincarnates as Harry fic. Set in OotP and beyond.

In this Dragon Ball Z/Code Geass "what-if" crossover fanfic, Prince Frieza begins to invade Britannia with his newest soldier, Kreeg, who shares similar ties with the fallen country. Who is Kreeg, and what intentions does she have? Warning: Character deaths are within this fanfic, and you won't believe who will bite the dust, even though this is non-canon.

Haruto Tokishima gets teleported from his timline to an alternate timelime. Japan was in an rebellion called the Black Rebellion. He gose and gets involved in the rebellion.

Lelouch has returned from hell and once again fighting another war that he felt so familiar, his presence will bring hope those who follow and despair for those who oppose him. Let the world know No greater good. No just cause only destruction to his enemies. A new War that will determine who will rule this world.(This is the real one, not the teaser)

Reboot of Dominance of Darkness, five years ago when Japan became Area 11 the former prince Lelouch was converted into a vampire. Now after five years of training he is ready to set out on his destined path to become the new Prince of Darkness and succeed his ancestor Dracula. Unaware that dark forces threaten humanity and he just might their only chance to survive. Lelouch/harem
