Dapuffster is a smasher from New Jersey who started going to Melee tournaments in April 2005. He mained Jigglypuff in the first three iterations of Super Smash Bros. and has used it as a secondary in Smash 4; he gained notoriety in Brawl in particular for being one of the very few competitive Jigglypuff players in the game, and being virtually the only one to gain good enough results to achieve beyond local recognition for his Jigglypuff abilities in Brawl besides Hungrybox. This would lead to Dapuffster being recognized as the best Brawl Jigglypuff player in the world. Despite his notoriety with Jigglypuff, he would end up dropping it in favor of Diddy Kong.
Dapuffster played Smash competitively in Smash 4, though despite his namesake, he mained Mii Brawler and became to be known as the best Mii Brawler in the world, being able to win sets against other top level players such as Dabuz, Nairo, Salem, 6WX, NAKAT and ADHD, as well as taking games off of the former best player in the world ZeRo. He was formerly ranked 7th on the Tristate Smash 4 Power Rankings.
In July 2006, Dapuffster created a YouTube account with the name Jigglymaster, that he still maintains. He currently has videos containing Smash 64, Melee, Brawl and Smash 4 videos; he also made tutorial videos on how to play as Jigglypuff in Smash 64, Melee, Brawl, and M.U.G.E.N. He has additionally uploaded several videos of Garry's Mod and his self-drawn 2D animations. While he doesn't upload frequently, his channel has amassed a fairly large following, having gained over 24,000 subscribers and 8 million total views to date.
In late 2015, Dapuffster retired from Smash Bros due to his new webcomic called "Champions of The Melting Pot" which is released on his website alexoshrin.com 3 days per week, as well as the legality issues with Mii Fighters nearly always preventing him from using Mii Brawler's custom moves, while major TOs remained obstinate in restricting Miis despite Dapuffster's and other Mii players' advocacy efforts. He was also diagnosed with testicular cancer and started chemotherapy in spring of 2016, and fully recovered by late summer of that same year.
