Spiker (Sonic the Hedgehog 2)

Description:
Spiker is a bug-like round ball that hangs on the cavern ceilings in the Hill Top Zone in Sonic the Hedgehog 2 (16-bit). If you spot one of these, immediately run by it to avoid it, because it will shoot its spiky drill at you if you aren't paying attention. This bot is a special part of Dr. Robotnik's Badnik army.

Sonic the Comic:
Spiker plays a role of a soldier in Dr. Robotnik's army.
