Superboy-Prime

Superboy-Prime is one of the many variations of Superman in the DC universe but he became unhinged following the destruction of his world and became one of the main antagonists of the Crisis On Infinite Earths storyline. Plus, also one of the most powerful supervillains in DC Comics.

Why He Sucks

 * 1) At first he was an unexpected hero from the original Crisis, but he was later grabbed by writers and re-tooled into a brainless, self-entitled brat who went on super-powered temper tantrums against comic heroes for not being who he wanted them to be. He is basically a villain. Not even a good villain, a poorly written villain.
 * 2) He seriously think I'm a hero after all the chaos he caused!
 * 3) He has got all the powers of Silver Comic Book Age Superman, but he love to abuse them.
 * 4) Not only am he's fully aware that I'm a comic book character, My world is literally your world. For all you know, he could be watching you now.
 * 5) He hates nearly all the superheroes in the DC Universe, and tried to kill most if not all of them.
 * 6) While original Superman was kind superhero, this version is complete opposite as he's a complete monster unlike the original one and is the worst variation of Superman.
