I'm a Harry Potter Wizard and I Ended Up in 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)
