I'm a Harry Potter Wizard and I Ended Up in a Hero World!

I was once a normal guy. Then I died and became the greatest wizard of my new world and got ostracized by morons because they are morons. Now I am in a world that has superheroes but somehow managed to convince themselves that leaving Nazis alive is smart. I got a lot of work to do.Warnings:-Superhero Crossover based on Worm-Every canon material can suck it-Harem-Morally a bit weird MC(he might enslave people or he might help kittens get off from trees)-OP MC(Harry Potter magic taken to the illogical extreme)-Any character from any Hero franchise can appear because why not?-Inspired by DarkWolfShiro's Super Villain story
