Marvel's Black Steel MBS

Nothing special, it's just that your average nigga end's up dying while following his heart as he protects a woman from rape; you know, the usual BS. Dude ends up dying, only to reincarnate in a world full of people that can destroy universes on a whim, and all that other crazy stuff, lucky for our MC, he happens to meet a chill yet powerful being that reincarnates him with the potential of the strongest version of Superman; Superman Prime One-Million.

Would like to point out, MC won't be an edgy villain or anything of the sort; he's got a good heart, and will be raised by kindhearted parents, though as it is the marvel universe and the not the goody two shoes DC universe, he will kill people, though, only when absolutely required to. Also, this novel is a slightly slow, so you've been warned.
Ps. I've set this novel up for both a Harem and Non-Harem route, so really it depends what ya'll want, so you gotta let me know; though like I said, the novel is a little slow on the uptake, so don't expect that much romance in the beginning.
I also haven't read any of the marvel comics, so all of my knowledge is coming from the movies and wiki-fandom, so don't expect me to get super in depth on comic lore.
Although I know this kind of novel has been done several times before, I've only read like two that I really fucked with, so I wanted to make my own, hopefully ya'll enjoy and if you do, might as well leave a review
