I was reading Superboy's wiki page and I was wondering after the Crisis on Infinite Earths separated Superman and Superboy, how did Superboy become Superboy-Prime if he died in Legion of Super-Heroes #38? 
 
Legion of Super-Heroes #38

Prime is an alternate universe Superboy.  He's not quite the Silver Age Superboy, just the Earth-Prime counterpart to him.

He wasn't even made in the Silver Age. Superboy Prime was introduced in the Bronze Age. He's also from a different universe - he isn't SA Superman as a boy.

" @Cap4Prez: Superboy-Prime isn't the same as SA Superboy. SB-Prime comes from an alternative earth called Earth-Prime where he was the first superhuman of his world or second, not sure if Pre-Crisis Ultra was from there too right now. After CIIE he was the only survivor of his universe and along with other survivors he went to live in a paradise dimension. The Superboy that died was actually from a pocket dimension. See, after CIIE Superman's career as Superboy was erased from canon. But this was creating some temporal anomalies with the Legion so Time Trapper created a pocket dimension with its own Superboy. So every time the Legion was traveling to the past to see Superboy, was actually traveling to the past of the pocket dimension and not New Earth. That Superboy died there. Hope that helps. If I am wrong, please someone correct me. "

Wow clears up a lot. Thanks viners. Somebody used a very vague and unclear history for that part of the Supereboy page but I read the wiki again and somebody changed it so it reads more clear in detail. Not sure why it was so vague and confusing before but now it reads more like the way you guys describe it. Wish editors were more into accuracy. It'd be less confusing on the wikis.

Bronze Age? What?

just think of him as a pre crisis kryptonian though more realistic without i bust galaxies with a sneaze powers.
