Marvel Demon Gamer

MC from Marvel world is reborn with a rare mutant bloodline and Gamer System, he a has second chance to change his destiny. He will level up and rise to the top in Marvel world! I will do whatever I want with this fanfic. So expect a lot of crazy OP action and R-18. MC starts off as Demon. D.C , X-Men, MCU Marvel, and Fate[Anime] worlds fused.
