Fisher does occasional guest appearances in the animated series Metalocalypse where he voices the Metal Masked Assassin. He was also the inspiration for the character Nathan Explosion, the lead vocalist for Dethklok. Nathan shares a similar physical appearance to George, headbangs in a windmill fashion, and also lived in Florida, although Fisher was born in Baltimore and moved to Florida later in life.
At the Blizzcon event in October 2011, Blizzard's and the band's 'LVL 90 ETC's decision to feature George Fisher's censored video expressing his dislike of the Alliance (a faction in WoW) as a lead-in to the LVL90 ETC and Fisher's joint musical performance caused an outcry. Spurred on by GLAAD, gaygamer.net published an article questioning the company's and band's tolerance of the views expressed in the uncensored version of the video, which included a number of homophobic remarks, one anti-'emo' remark, and a desire for the alliance to 'die'. The story quickly gained traction, and was subsequently addressed by the company with an open apology letter.
