Gemini the Wizard here is one of the few badguys to live long enough to tangle with Thundarr the Barbarian in two different episodes. I love the wizards in the world of Thundarr. Almost all of them are mutated techno-monsters who left their humanity behind long ago. Gemini's particular deal is that he has two faces and a spinning neck. Most of the time you can deal with the friendly, benevolent, soft-spoken face. But piss him off and his head rotates 180 degrees and the angry, yelling, zap-you-with-eyebeams persona emerges.
"Man, is there anything Jeff CAN'T do when it comes to gaming? This guy is like a critical 20 every roll. Jeff can bite the heads offa five game geeks, including their sorry-ass DM, and spit 'em into a large duffel bag ONE AT A TIME!...that's just the kind of messed up bastard he is! You think yer a gamer, punk? Well..do ya? Jeff will depants your weasel-ass right in front of your grandma."
