The Weapon X Project decided to start on clones. With some of Superman's DNA (obtained from Lex Luthor, for a price that is) they created: WEASPON C1. He grew to about the size of a teen till he was broke out of there by Wolverine. Then he discovered Superman, his "father". He then got his idea of a superhero costume and worked alongside Superman sometimes, but mostly on his own. He also obtained the name Kon-El.
