The Big Foot or Sasquatch is a large, fur-covered creature that appears in the film TMNT.
Like the rest of the Thirteen Monsters, Bigfoot escaped from a portal in South America 3000 years ago, and has been terrorizing humanity ever since. This monster inhabits Canada and the US Pacific Northwest, where many legends about the creature have developed.
Bigfoot appears as a boss in the console/PC and PSP/DS versions of the 2007 video game, and is the sole boss of TMNT: Ninja Adventures. The Bigfoot chases you in the Turtle Van level of TMNT: Power of 4.
- Like the rest of the Thirteen Monsters and Marlin's Cryptids, the Bigfoot is based on a real-world legend, though in the story it is the basis of those legends.
- While several Bigfoot or Sasquatch have appeared in TMNT fiction, it is likely these are not intended to be the same character, but rather different interpretations of the Bigfoot legend.
