The Adventures of Superboy

After Superboy's near death run-in with Luthor, he is taken to yet another universe, one of which an alternate Dr. Winger, Luthor, who is now a doctor, and Superman exist. Dr. Winger admits that he's repsonsible for Superboy's latest (and dangerous) adventure, and they help him recover. Superboy has to convince his older alternate to allow him to go to the previous universe to save the younger version of himself, so that their paths in all worlds are corrected.
