Leffen
William Hjelte (born 16 October 1994), better known as Leffen, is a Swedish gamer who primarily plays Super Smash Bros. Melee, in which he is a Fox main. In the Melee scene he is considered one of the dominant "Top 6" players, the others being Juan "Hungrybox" Debiedma, Joseph "Mango" Marquez, Adam "Armada" Lindgren, Jason "Mew2King" Zimmerman, and Kevin "PPMD" Nanney. Though Leffen has only recently become considered among the very best Super Smash Bros. Melee players in the world, Melee It On Me ranked Hjelte 3rd best in the world in the summer of 2015, a substantial improvement from 14th in the world in 2013 and 6th in 2014.
