With a single wish Ty knew that nothing was beyond his power. He could remake the world however he desired, and no one would know the wiser, not unless Ty wanted them to. The possibilities overwhelmed Ty, he simply couldn't decide, what he wanted to do with this power, in tell, he saw an old comic of his and a brilliant idea formed in his mind.
He would make superheroes and villains real, and use them to effect change, to corrupt his world. With the method decided, he began to iron out the kinks before he sit everything in motion. The world shall have always had these heroes and villains, people with amazing powers, comparable to gods. Some have unique genes, special tech, possibly magic, they may be a demi-god, or even be a god them self.
Ty made such issues as the destruction of cities, something hand waved and easily fixed. The lives that should be lost in such an event, that doesn't happen because of "luck", oh and of course the shelters made just for this helps to. But that wasn't it, Ty was by no means a saint, he was very lustful, if he had his way, he'd have someone in his bed every day. And thus this world, would be lustful and slutty, just like Ty battles between heroes and villains will end with a climax, in more than one sense of the word.
