The Turtle Slug is a large, blue turtle with a collar on its neck. It is armed with a Vulcan on one side and a large bazooka on the other. The bazooka shoots out homing missiles at enemies. The pilot controls the Turtle Slug's weapons by the use of a cockpit placed on top of the turtle.
The Turtle Slug makes its debut in Metal Slug Infinity with its coloration revealed. It is an SSR Slug that anyone can pilot. It is a damage-based Slug with attack strength starting at 571%. As there's no water in the stages, it moves by crawling against the ground.
