According to TMZ, the actor passed away last night at the age of 68. Avery is most famous for his role as Uncle Phil on the sitcom The Fresh Prince of Bel Air, but he has some pretty impressive nerd cred as well.
Avery was the voice of Shredder on the 1980's Teenage Mutant Ninja Turtles animated series.
But there's more! He also provided the voice for James Rhodes, AKA War Machine, in the 1990's Iron Man cartoon and for a few episodes of the Spider-Man cartoon. Hang on. There's still more. In the English language version of Fist of the North Star, Avery provided the voice for Boss Fang.
Oh, and he also played Klingon General K'Vagh for two episodes on Star Trek: Enterprise.
Pretty impressive. He will be missed.
