You Can Take the Man out of the Super, But You Can't Take the Super out of the Boy
Story featuring Superman
Storyline: Lex Luthor de-ages Superman back to boyhood in an attempt to beat him when he has lost his years of experience (ignoring that Superboy was a perfectly capable hero at that age). The origin of Lex Luthor is retold. Superman consults with the similarly de-aged Flash and Batman before the trio take on Luthor again, and defeat him.
