Snorlax, known in Japan as Kabigon, is a Pokémon species in Nintendo and Game Freak's Pokémon franchise. Created by Ken Sugimori, Snorlax first appeared in the video games Pokémon Red and Blue and subsequent sequels, later appearing in various merchandise, spinoff titles and animated and printed adaptations of the franchise. It is voiced by Katsuyuki Konishi in the Japanese versions of the Pokémon anime and the Super Smash Bros. series of video games, while the character was voiced by Hitoshi Takagi and Mitsuru Ogata in the animated shorts Pikachu's Rescue Adventure and Pikachu & Pichu respectively. In its English-language appearances, it was originally voiced by Michael Haigney, and later Eric Stuart. Known as the Sleeping Pokémon, Snorlax has been said to weigh over 1,000 pounds and for a time was considered the heaviest known Pokémon. Snorlax has been utilized by the anime series main character Ash Ketchum, and Pokémon Adventures main character Red. Snorlax has received mixed reception, GameSpy calling it "downright silly", while IGN says it is "by far the most powerful Pokémon of all".
