Getting 5 Wishes and becoming a monster in mcu

This is my first novel so it might be bad and grammer to. This is not going to be a story where mc falls in love or helps people he will not stand for people that think the are better than hime or people that try to mock him. He will not hesitate to put people in there place when trying to pick a fight. This novel might go to different worlds but im still thinking about it and this is mostly me and my imagination but i might put some anime or tv/movie worlds like marvel or some anime world. Atom was a 18 year old boy that didn't like anyone he thinks everyone is stupid. Atom like to read fantasy novels and books mostly the ones where the mc gets to go to a different world and be a different race like an elf, dragon, vampire, and more. he always wanted to be something else even if it was a bird or snake he just hated his own race he thought they are dumb. And one day accidentally bumped into a group of guys when he was walking on the sidewalk and they were all dunk buff dudes and they ended up beating him to death but hes in a white room with a big bald dude.
