Alright first I always like the lizardman from Warhammer 2 & 3, and then I realize there not much Warhammer crossover. So I decide to make a crossover with my favorite anime, overlord, alright all image I use go to the creators, alright so this might have slow update

El dios tzeetch viendo en el velo de realidades vio la magia de ydrassil , el como el dios de la magia y el cambio quizo su magia asi que trajo al nuevo mundo del mundo de overlord pero perdio un poco la conexion con el al traerlo por subestimar la magia de ydrassil

A Gate opened in a certain world, one world where Mankind is hunted down, weak, limited. A Gate opened, welcoming an Imperium, where Mankind is also haunted, but one where humanity is willing to face the monsters that surrounds it. Two forces, each one totally opposite to the other. And in the middle of all, innocents who never thought this dread fate could fall over them.

During the End Times, a group of survivors fled to another new world the surviving gods managed to make but it's heavily implied they didn't make it or is it? Because that new world they fled to is…well the New World. Now, Ainz Ooal Gown has appeared in the New World which is now the Ninth Realm, and is now in contact with the Mortal Realms. Adopted it from GhazzgullThrakan.

Momonga now an Necron overlord wake from the long slumber discovering the universe of the 41 millennium

Ainz gets Isekaid' into 40k and the planet blows up. Cain has morning tea and embarks on his hundred and seventh suicide mission. Just another average day in the Imperium. M because come on, it's 40k.

When the Great Tomb of Nazarick was teleported far from it's original place, other beings come to replace their place in the world of Selpunoter. Some will bring a new age to this world, others will seek to destroy it. But one thing is for certain: only the strongest will survive in this harsh new world.

Nazarick shows up in warhammer world in 2400IC after a hypothetical end of Overlord.

Ainz Ooal Gown has come to the New world but he isn’t alone. A close friend of his has also arrived in the New World. Except he wasn’t playing YGGDRASIL, he was playing a DMMO-RPG where there is no peace among the stars. Only an eternity of carnage and slaughter and the laughter of thirsting gods. Oh yeah, also this freaky motherfucker got four arms. LMAO.

What happens when Ainz Ooal Gown meets with he world of Warhammer fantasy and what would his adventures would be with the Men of the Empire and their allies and the ruinous powers to our bois Greenskins.

The Emperor lost, Humanity surrounded by enemies was decimated. Still, the flames of hope didn't die, something gave him a chance to start over and to make right out of all the mistakes he'd made. A new universe but with the same objective. The light must prevail and humanity shall triumph. The Avatar of Order has arrived in the new world and it shall tremble under his feet.

My ideas

A lost Captain. His Last stand made and his Brother killed to a man. Himself Curiously alive he appears in a village, with little recollection of his last moments. The Weight of a lie he as told everyone on his shoulders, one even his brothers in the Lamenters Chapter did not know.

100 Years after the first advent, Ainz rules the world from his capital seat of Nazarick. However, instead of a new player being added to the fray, the sky's shift and change, as the planet had been torn through warpspace and time into the grim dark of the 40k galaxy.

6 dorks from the real world who are fans of both Overlord and 40k ended up trapped in the 40k universe after playing the Black crusade rpg. Then they found that the new world is a Feral world. Ainz finally found someone whom he can relate to... even if they’re all a little crazy. (DISCONTINUED)

Warp storms engulf the new world. Even Nazarick can feel this chaotic power. What will the overlord of Nazarick do after arriving to a place where the only future is endless war? one grimdark future where peace is just a dream.

Instead of the "New World" The tomb of Nazarick appear in the "Old World"

Es el cuadragésimo primer milenio, en una galaxia hostil las razas conquistadas hace milenios por Ainz Ooal Gown en la sagrada Terra ahora intentan sobrevivir a un universo despiadado que solo busca destruir el imperio que el dios overlord ha creado. En el siniestro futuro lejano, solo hay guerra.
