Marvel: Mutants Shall Rule!

As World War 2 is on the horizon, a group of mutants known as the X-Men discover the traces of an ancient Anti-mutant Organization that kidnaps young mutant children and brainwashes them into fighting and hating their kind, and so the X-Men now must fight/destroy this vile group and free those Children! However, it won't be so easy... ========= ========= Attention please, I would like to say a couple of things before we get this started: We will have a main character, but he won't be a reincarnated guy or have ANY future knowledge. The Main Character will only appear later in the story, the plot will revolve mostly around X-Men in the beginning. The Universe is 100% Au so don't expect similarities, they will be some but don't expect much. He will be a villain and I mean a full-fledged villain, he will be racist, evil, radical, and more. The Mc will be a mutant, an omega one at that and his abilities will be those of another verse, Chainsaw Man to be exact, he will be OP but he won't be OP at the same time, you guys will see. Disclaimer: I don't own Marvel, and I don't own Chainsaw man, this is just fanfiction. So please nobody sue me...
