8) Superboy (Conner Kent)
His origins aren’t as complex as Wiccan and Speed, but Conner Kent also isn’t your average Super-Son. In the wake of Superman’s death at the hands of Doomsday, Project Cadmus made a half-Kryptonian/half-human clone of Superman. And guess where the human DNA came from? Supes’ longtime nemesis, Lex Luthor!
What makes Superboy such an interesting character is the conflict between his Kryptonian and human halves and his attempt to embrace Superman’s heroism and not be tempted by his Luthor dark side. Conner’s finest hour comes in the Young Justice TV series, in which he was pretty much the breakout character.
Despite being a brilliant hero, though, we don’t feel we can put Conner up any higher on this list due to the varying portrayal of his relationship with Superman. Sometimes he’s treated like a son, but they usually have a strained relationship of a big brother and a younger brother, or even cousins (like Supes and Supergirl).
