UnknownForce is an American Melee Sheik player, but has been known to use other characters sporadically in tournaments or casual matches. He is part of the "Ninja Turtles" crew, alongside players such as KoreanDJ, Krazyjones, Hayato, Yoyo, Roga, Kalot, and a few other members. He was interviewed for the The Smash Brothers documentary. With the exception of his interview for the smash documentary, he's kept a low profile in the smash community since he began to attend tournaments for the first time at MLG Boston (October 2004). He retired from serious tournament play around April of 2006, but has still been known to attend tournaments once in a blue moon. At his peak, he had a number of tournament wins against the top 25 players in the first US "top 25" rankings list created by HugS and Chillin.
