Superboy Prime

Superboy Prime is a cynical reflection of Superman, coming from a world where superheroes only existed as fiction - except for him.

Originally destined to be the greatest superhero and the world's chosen champion in the fight against evil, Superboy-Prime, left scarred by the traumatic events he witnessed, has become a brutal killing machine. Years of isolation while endlessly viewing the events of a life he could no longer have put severe stress on his already fragile mind. When the turning point came and he accidentally killed several heroes, his mind finally snapped and he retreated into denial of the horrific nature of his actions. Superboy Prime has buried any remorse or compassion under an insane belief that since he is a Superman, everything that he does is right and views any other reality apart from his own as an imperfect duplicate of his world. All of this has left Prime in a psychotic state of mind unable to distinguish the morality of his own actions and the ability to commit even the most heinous of deeds with no guilt at all. Hellbent on nothing but killing numerous superheroes while also leaving an endless wave of utter destruction in his wake and as such, he is one of the most dangerous villains in the universe.

Superboy-Prime has had a collection of powers over time, being one of the many alternate Supermen of DC comics he possesses standard Kryptonian powers (Super Strength, invulnerability, super speed, Heat vision, etc.) but in the level of Silver Age Superman, who could sneeze away entire solar systems. He is also able to amplify his powers via his power-armor, becoming more and more powerful. At the peak of his power Superboy Prime could punch through dimensions and cause ripples through space-time. Due to Superboy-Prime being from another universe, he is immune to most of Superman's weaknesses, such as magic and kryptonite. His suit is also designed to constantly feed him yellow sun radiation and keep him at peak power even when exposed to red sun radiation.
