Andy O'Brien, also known as AOB, is an American smasher well-known for being a prominent Jigglypuff and Donkey Kong player in his earlier days, and for having hosted the Show Me Your Moves (SMYM) tournament series in Champaign, Illinois since 2004.
Andy's first experience in competitive Smash was in March of 2003, when he and longtime friend Amorasaki attended Snexus 1. He proved to be an upstart at Flame of Bowser 1 in October 2003, where he breezed through then-notable players Asmog, Fusegen, and KishCubed to take third place. His subsequent release of match videos and a widely-watched Jigglypuff demonstration video titled PuffStuff at a time when comparatively few Melee videos were available led to the common (but mistaken) belief that he was one of the better players nationwide. Still, he became one of the first and most influential Jigglypuff idols, although his tournament performance was overshadowed by Zulu, KillaOR, and KishPrime. More recently, he also enjoyed renown with Donkey Kong before being overshadowed by Bum.
Through his early roots and successful tournament series, Andy has attained a certain degree of influence in the Midwest Melee community. He continues to host Show Me Your Moves, which has become the most prominent Melee tournament series in the Midwest. SMYM 11 took place on March 13, 2010.
