A reincarnated soul ends up with rob, as he got three non overpowered wishes, one for the suit of the American greatest hero, two for the suit to have magical abilities, and three for him to have batman level intellect and resources, as he knew with time a suit like that would grow very overpowered, as no true power limit was given, making it basically able to gain powers whenever needed, adding magic just makes it stronger.
The wishes work, and he is sent into marvel, the only thing is, the Rob making all those changes didn't change one thing, the suit makers want and purpose for the suit, for find a being of strong moral goodness to help others and save the day.
The changes to the suit, upgrading it with magic and even changing the aliens to be so, made them more powerful two, as the suit would find the reincarnated man unworthy of the suits power, seeing him as like all other normal reincarnated humans, disgusting libido obsessed beings, willing to lie, cheat, mind control, the works, when the suit even saw he thought of the beings of that world, especially the woman as his playthings, it left immediately.
It soon found a homeless boy, and would bond with him, sensing the true goodness in the boys heart, the suit would guide him him morally, but..cosmic jokers where at play, as the aliens forgot to put in an instruction manel!
This is not the story of a evil reincarnater, this is the story of a man given a task of hope and goodness, and he would see it though.
