A Wal-Mart exclusive, Grindcore is a redeco of Cybertron Landmine, transforming into a green wheeled front loader with a rear-mounted pile driver. His bucket shovel can be raised up and down, while his gimmick is unusual in that the Cyber Planet Key slot is in his rear wheels. To configure him into attack mode, one flips up the rear wheels (there are smaller wheels to support the rear end of the vehicle to compensate), inserts the Cyber Key into the wheel-hub slots and twists, deploying blades around the circumference of each tire.
