Spikebonkers are cone-shaped Badniks assigned to security aboard the Death Egg. They hover around and attempt to bludgeon inruders to death with a single rotating mace-ball. The mace-ball can be launched a set distance and is magnetically pulled back to its orbit around the Spikebonker robot. No Spikebonkers have been seen since the Death Egg's destruction, so their production was short-lived.
