Through circumstances beyond their control, people develop extraordinary powers in a world that grows to fear them. But with the help of a rich, mysterious benefactor, these "mutants" use their gifts to save others from persecution as shady government organizations fight to hunt and control them.
That's the premise of Marvel's X-Men in a nutshell, and it's also the premise of Marvel's rip-off series Mutant X, a mostly forgotten TV show (unrelated to the comic of the same name) that ended twenty years ago today with an abrupt cliffhanger.
