Big Foot also appeared in Shadow the Hedgehog, where it is slightly darker in coloration with some silver outfit. In gameplay, they are the most powerful GUN's enforces, having a very solid armor that is more powerful than R7's and it takes nine hits with the Homing Attack and one shot by Shadow Rifle to destroy it. The Big Foot can fly and walk as well, but it is very slow. Like in Sonic Adventure 2, they have a human on their cockpit that controls the robots. However when destroyed, no humans will get out of it. They usually leave behind a heavy machine gun when destroyed. A stronger variant, the F-6r model, appears in three stages: in this case, The ARK, GUN Fortress and Black Comet. This variants is even more stronger than the Black Oak, requiring 15 hits to destroy it.
The Hot Shot is exactly the same as Big Foot, 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.
The 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.
Big Foot begins by flying up and strafing the ground with machine- gun fire. It’s easily seen and he’s not moving very fast. Run in a wide circle to avoid it. After a few passes with the machine guns, Big Foot will land and the Missile bays will open. Predictably, Missiles shoot out at you. Again, run around the edge of the circle until the barrage stops. Try to time it so that you’re close to Big Foot when the bay doors close. As soon as they do, leap high in the air and Homing Attack on Big Foot’s cockpit. After the fourth hit, Big Foot collapses.
As an easier way to defeat the Big Foot in less than a minute, the player can jump on top of containers before it destroys them, and launch a Homing Attack into it.
In the anime series Sonic X, the Big Foot appeared in "Shadow Knows". After escaping the Gun Beetles, Sonic was confronted by a Big Foot. Sonic used his Spin Attack to defeat the Big Foot. Not beaten through, the robot fired several missiles at Sonic which he directed back at it, blowing the mech to pieces.
Big Foot is named after the legendary cryptid, the Bigfoot (or Sasquatch), because it is a giant compared to characters like Sonic.
According to the official site for Sonic Adventure 2, the Big Foot belongs to the Scorpion troop.
