But without clones you wouldn't have Superboy, Bizarro, X-23, (Ultimate) Jessica Drew, the X-Babies... :hehe

You wouldn't have Madelyne Pryor retconned into being Jean Grey's clone, thus ruining Scott Summer's entire personality and tearing away any future credit to the morals he had always had before then. Guy Gardner's clone, the entirely original Joe Gardner, wouldn't exist. Or Lex Luthor faking his own death, putting his consciousness into a clone, using an Australian accent, and claiming to be his own son. Inertia. Ragnarok. Ultimate Gwen Stacy/Carnage amalgam. The list goes on.
