How is he a clone? A clone, by definition, is someone whose DNA, overall, is an exact copy of someone else's DNA. Superboy's DNA, overall, isn't an exact copy of anybody. In fact, as far as we know, his DNA, overall, is completely unique. The fact that he was born in a lab or that he got part of it from someone else doesn't mean that he's a clone. In fact, it doesn't make him any different from test-tube babies.
