The Superboy mantle seems to have a particular curse in the DCU for anyone who dares to take it on. It seems that those who become Superman's sidekick are destined to lose out on some crucial years of their life.
While Clark Kent might have been the first person to don the Superboy identity, the role has traditionally been reserved for younger heroes with a similar range of powers. Conner Kent was one of the most well-known bearers of the title after he burst onto the scene as a Superman replacement, and even Superman's son Jon filled the role. But Superboy experienced an age change just a short time into his superhero career, thanks to being held hostage on Earth-3 for a few years. While Jon's made his peace with the event, it was a development that left a lot of fans upset. And as it turns out, this is a fairly common occurrence for those who work alongside Superman.
