Yeah I know that could be about a thousand comicsc at this point. I can't remember the actual name of the hero. I remember reading about it a few years ago. From what I remember the guy turns evil after
he goes to the moon for a few minutes after being tired of hearing people constantly calling for his help, and during that time a bunch of children are killed and he snaps.
He even
destroys a country
at some point, I think. It's not Invincible, although it is a one word title.
I'm far from high end, I just know what suits me.
