7. Lord Satanis
No, I didn't steal this entry from every twelve year old's Dungeons and Dragons campaign, he's a real DC Comics character.
Lord Satanis hails from the far future, where magic had become more important than science. Either A: this was a reaction to the anti-magic pro-science society of the 64th century that produced Flash Villain Abra Kadabra or B: I am a gigantic nerd who thinks way too much about these things.
Satanis overthrew the magic ruler of his time, but before he could acquire the runestone which gave him ultimate power, it was sent back in time to keep it out of Satanis's grasp. Satanis followed it back and fought Superman for it. In the process, his girlfriend, also seeking control of the runestone, summoned Satan the Devil himself, who dragged Lord Satanis down to hell. Which had to be awkward.
Meeting your idol is always weird, much weirder when you named yourself after them.
