Spikebonkers are security Badniks stationed aboard Dr. Eggman's Death Egg battle fortress. They have domed heads and cone-shaped lower bodies, and a canister on their backs. They slowly hover left to right with a spiky mace-ball rotating around their bodies, which they will throw at intruders. Unlike the Orbinaut, when the Spikebonker throws its mace-ball, it is pulled back into its rotation around the robot's body.
