|F-6t Big Foot|
The F-6t Big Foot - Ground Air Combat Walkers is a boss in Sonic Adventure 2, a recurring enemy in Shadow the Hedgehog, and makes an appearance in Sonic X. It is a G.U.N. robot, controlled by a soldier. It made its first appearance in Sonic Adventure 2, as the first boss of the hero story. It is fought after City Escape.
The Bigfoot is a mechanical walker that is armed with a machine gun and missile launchers. Its main weak-point is the cockpit, which requires four strikes to defeat it.
Shadow the Hedgehog
It was confirmed that a similar G.U.N. robot in Shadow the Hedgehog was a Bigfoot when Omega said, "Vital human life signs approaching. Enemy mech Bigfoot detected!". In that same game, Eggman in the Iron Jungle said it looks like Bigfoot. However in Sonic Adventure 2, Shadow didn't face Bigfoot, he faced Hot Shot. Shadow did encounter Sonic after the Bigfoot fight; in fact, Shadow stood on top of Bigfoot.
Bigfoot has two main weapons, a machine gun (Gatling Gun) and missiles (Hot Shot and Flying Dog also have these weapons, but also have a lock-on plasma cannon equipped with them.)
Similar G.U.N robots
There are variations of the Bigfoot walker, possibly different models of it. Both of them only appeared in Sonic Adventure 2.
- Hot Shot: Hot Shot is exactly the same as Bigfoot, with the same weapons and capabilities. However, it also has an added lock-on laser its front. Hot Shot is deployed to fight Shadow when he was set free from stasis by Dr. Eggman.
- Flying Dog: Flying Dog is basically the Hot Shot without legs. Without the walkers, Flying Dog remains hovering during its operation. It also has an improved defense, as it takes five strikes to destroy. When four strikes has been dealt, the Flying Dog simply stops using missiles and machine guns, and instead just launches the plasma cannon repeatedly. It was deployed on security hall against Rouge the Bat, who was stealing three Chaos Emeralds from the vault.
The F-6t Big Foot robots have made several cameos throughout the Sonic the Hedgehog comic series published by Archie Comics. They had appeared during the brief attack by Dr. Eggman at Central City. (SU #38)
- Bigfoot is named after the legendary cryptid, the Bigfoot (or Sasquatch), because it is a giant compared to characters like Sonic.
