Last night, Spike TV's tattoo reality series Ink Master  got folks talking and tweeting with a special DC Comics villains-themed episode...including Batman artist Greg Capullo, who served as a guest judge on the episode and live tweeted during its debut. Joining him were plenty of comic book fans and tattoo enthusiasts, as well as several of this seasons Ink Master contestants. Check out some some of the best comments and exchanges below, and be sure to visit Ink Master's voting page to see and vote for your favorite of last night's super-villain tattoos.
