There is alot of potential. I think the third one was supposed to be the clone from leader from Kryptons past. the one who lead the rebellion.
Thats wat I like about Superboy is his potential
@stephens2177: Yeah, I dont want him to be stronger than Superman, just toe-to-toe.... But I do think he has greater room for character development, Superman is and always should be the boyscout. This leaves Superboy to one day (far in the future) to take Superman place but also making room for him to make mistakes and be more human. I love Superman, but for him to be Supes, he has gotta stay true to being the light of DC. Superboy can be the darker side of the superman family.
