Dr. Twinkletits
One of my favorite non-band member characters was Dr. Twinkletits (remember, TWINK-LET-ITS not TWINKLE-TITS lol) Yes, he was annoying, but thats what made him great. Also that he was a murdering psychopath who ended up as food for the yard wolves lol.
Best of all, voiced by Jeff Loomis. As a Nevermore fan, this was also great.
Who was y'all's favorite non-band member character? (Other than Offdenson (sp?) cuz he was, not a band member but a valued part of the team who wont let anyone <guitar riff> with his bread and butter)
