The Choppers are yellow mechanical fish based on piranhas. They have a sharp dorsal fin, thin nostrils, completely red eyes with black pupils and an orange rear with a similarly colored tail, but have no pelvic fins. They also have several serrated teeth and orange screws on their jaw joints.
Having lured Sonic and Tails on a vacation, a trio of Choppers were set loose on the duo by Scratch and Grounder when they sunk on their way to Sanpelagroso. Before the Choppers could reach them though, Sonic reined them in and had them drag him to Sanpelagroso (by water skiing) where they beached.
Powers and abilities
The Choppers are very fast in the water, swimming at speeds compatible to a motorboat. They also have sharp mouths that can chew through solid ground with ease.
