Sometimes, you can find some real surprises when you go back and read the classic comics of the Silver Age. For example, I'd been familiar with the X-Men villain Sauron for ages, but I'd always assumed that his name had something to do with the fact that he was a sort of weird not-quite-mutant dinosaur vampire type thing. (He was scratched by pterodactyls in the Savage Land, and that woke his latent mutant abilities...I guess...and so he became an energy-draining hypnotizing pterodactyl-man.)
(The above was not the insane bit, I promise.)
But as I say, I'd always assumed that he was named "Sauron" because he was some sort of dinosaur...or possibly, in a bit of a stretch, because his wings allowed him to soar through the air and he was a lousy speller or something. But no, when I got into "Essential Classic X-Men, Volume Three", and finally read his origin for the first time, I found the true reason for his name.
He was a huge "Lord of the Rings" fan before he was scratched, you see, and when he started to mutate, he felt himself growing more evil. "In fact," he shouts, "I am now so evil that I shall name my new self after the most evil character in all of fantasy literature...Sauron!"
No, I'm not kidding. That really happened.
The really sad part is I actually see guys like this all the time, running around in MMOs. You sign into "City of Heroes" the day after they introduce dual blades as a fighting style, and suddenly you're surrounded by guys named things like "Drizzzt" with three "Z"s. Presumably like them, Sauron's true arch-nemesis is Copyright Infringement Lawsuit Man, with his dreaded ultimate weapon, the Cease and Desist!
(And of course, TSR circa 1981 is saying, "Wait, they went after us but they missed this?")
