The creation of legendary cartoonist Sergio Aragonés (who was soon joined in that questionable literary endeavor by producer/writer/friend-of-his Mark Evanier), Groo the Wanderer has fans all over the world.
The world's stupidest barbarian first appeared in print in 1982, though the concept was camped out in Sergio's mind and on his drawing board for several years before. The comic was an almost-instant hit, and Sergio and Mark have been producing Groo's further adventures for over 40 years with new issues still appearing…200 and counting. Groo, by the way, is not doing the counting because he can't!
