Ulysses

The Last Son of Earth, much like Superman, Ulysses was sent off planet by his parents many years ago, who thought Earth would soon be destroyed. Twenty-five years later, Ulysses returned to Earth, both surprised it still existed and wielding superpowers, similar to Superman's. Revealed he was actually adopted by Klerik in the 4th dimension and attempted to sacrifice 6 million of Earth's population in order to sustain that world. Upon failure and destruction of his homeworld, he turned on Superman.
