Spikes

For the obstacle in several Zones, see Spike trap.

Spikes is a first-generation Badnik created by Dr. Robotnik. It first appeared in Enter: Sonic and was directly based on the enemy from the Mega Drive game, Sonic the Hedgehog. Spike Badniks resemble hermit crabs. They have shells covered in spikes to protect them from being attacked from above. They move around on two wheels and attack by swiping enemies with their clawed forelegs.

An updated model, based on the Badnik from Sonic the Hedgehog 4: "Episode II", was introduced as part of the New Robotnik Empire.

Other Badniks, like Spiker and Turbo Spiker, have similar names but are completely different in design.
