Comic books bring together heroes to beat up scores of bad guys, and also inspire conventions that bring together scores of guys you could actually beat up, bad. For comic book-inspired clothing even a bully could love, check out Raptor Bandit Industries
Spilling from the hilariously off-kilter mind of a Cumberland, MD-born artist, Raptor hawks gear and prints, mostly drawn from/inspired by their creator's "Dr. McNinja" comic book: the saga of a judo-chopping masked physician battling laser-eyed goats, bazooka-toting gorillas, and the perception that he regularly abuses his parking privileges. McNinja gear includes tees or sweatshirts with the stethoscope-/katana-wielding protagonist mid jump-kick, a flaming "Ninja's Can't Catch You if You're on Fire", and the "High Five", depicting a gorilla high-fiving a shark in front of an explosion -- originally a scene from the comic with McNinja in place of the gorilla, which the creator eventually altered because "that would have been way too random". Non-nin-jitsu wackiness includes shirts like "Dolphin Revenge", with an angry fish mammal pointing a revolver, and the eponymous "Raptor Bandit", with a sombrero-sporting desperado riding a velociraptor, plus prints like the evil unicorn "Sparklelord", and a completely random "Campaign Poster" advertising running mates "Archibald: King of the Hobos" for president, and "A Trustworthy Mummy" for VP...although his true calling is clearly TP
For the comically bookish, compendiums of McNinja (MD)'s adventures are also for sale and updated tri-weekly online, perfect if you worry that being seen buying comic books means you'll never again score.
