The Groo Chronicles
Groo (the epithet "the Wanderer" is informal and rarely mentioned within the stories) first appeared as a parody of the brutal sword & sorcery heroes who were popular at the time of his creation in the 1970s, especially Conan the Barbarian as presented in Marvel Comics. Groo is an ugly large-nosed buffoon of unsurpassed stupidity who constantly misunderstands his surroundings. Possessed of superlative skills in swordsmanship (the only task at which he's remotely competent) he delights in combat but otherwise is a peaceable and remarkably honest fellow who tries to make his way through life as a mercenary or by working odd jobs. Unfortunately he is also indiscriminate in the use of his battle skills (prone to joyously leaping into any fray before attempting to ascertain the reasons for the fight, or even who is on what side) and incredibly accident-prone, and despite generally good intentions causes mass destruction wherever he goes. Most of his adventures end with him oblivious to the mayhem he has wrought, or fleeing an angry mob. As a result, his penchant for destruction has become so widely known and feared that just the news of Groo approaching is sometimes enough to cause chaos when the population reacts to the impending disaster. Groo occasionally meets with respect and good fortune, but it does not last. Businesses, towns, civilizations and cultures have all been unwittingly destroyed by Groo.
