It appears only in the Dark Story, trying to destroy Shadow after he was released in Iron Gate. Shadow likewise proceeded to fight and destroy it to demonstrate to Eggman a taste of the power he possessed.
Judging by the pilot's pre-battle quote, the Hot Shot walker used against Shadow belonged to GUN's Scorpion Troops.
The Hot Shot is a mechanical walker with a machine gun, missile launchers, and a lock-on plasma cannon. Its main weak-point is the cockpit, requiring four strikes to defeat it. Hot Shot bears a resemblance to its Hero story equivalent F-6t Big Foot, although Big Foot lacks the lock on cannon that its counterparts possess, making Hot Shot slightly more dangerous.
- It has nearly the exact same design as the F-6t Big Foot.
