Reborn in DC

Sebastian Tempest is a man who discovers he has become a slime after a strange incident. He is forced to come to terms with his new form and abilities and uses them to survive in a world where he is the only one of his kind. He is primarily motivated by self-interest, but as he travels and interacts with others, he starts to uncover a greater purpose and destiny for himself. He faces challenges, makes allies and enemies, and ultimately must decide what kind of person he wants to be in this new world.

I suggest you get a basic or decent understanding of the shows and/or books this fic takes place in, or you may be lost. Though, I will try to describe things to the best of my ability.
