In Shadow the Hedgehog, the Big Foot itself does not appear. However, there are two variants of it that appear as regular enemies: the Big Foot Type A and the Big Foot Type B. These models are slightly darker in coloration with some silver highlights, and have very solid armor that is more powerful than R7's. Both of these enemies are classified as Big Foot models.
The Hot Shot is almost 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 Big Foot Type A is the second strongest standard enemy belonging to G.U.N. following the F-gr Big Foot. In Shadow the Hedgehog, they carry Gatling guns which Shadow can pick up after he has defeated them. It is much stronger than the Sonic Adventure 2 variant and takes many more homing attacks to defeat.
The Big Foot Type B is a variant that utilizing 8-Shot RPGs to attack the player, with it's AI being far more advanced than the F-6 variant, and appears only in the later levels. Because of such, it is one of the strongest enemies in the game, being G.U.N's strongest unit. After being destroyed, it drops a lock-on missile launcher.
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 have been dealt, the Flying Dog simply stops using missiles and machine guns, and instead launches the plasma cannon repeatedly. It was deployed in security hall against Rouge the Bat, who was stealing three Chaos Emeralds from the vault located within.
Big Foot begins by flying up and strafing the ground with machine gun fire. It’s easily seen and does not move very fast. The player can 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 the player, who must once again run around the edge of the circle until the barrage stops. As soon as the missile pod's doors close, the player must leap high into the air and Homing Attack the Big Foot’s cockpit. After four hits, Big Foot will collapse.
As an easier way to defeat the Big Foot in less than a minute, the player can jump on top of Wooden Containers before it destroys them, and launch a Homing Attack at it. It is also possible to hit Big Foot's cockpit with a Bounce Attack while it is in the air.
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 entirely, 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).
According to the official site for Sonic Adventure 2, the Big Foot belongs to the Scorpion troop.
In the Dreamcast version of Sonic Adventure 2, it is possible to finish the F-6t Big Foot with the Light Speed Attack in one go. In the GameCube version and digital re-releases of the game, however, the Light Speed Attack only deals one hit's worth of damage when executed and then cancels itself.
