The Roller is one of Doctor Robotnik's first-generation Badniks. They have spherical bodies and may or may not be modelled after armadilloes. Their hardened bodies can withstand attacks quite well and they are capable of rolling into enemies and bowling them over. They first appeared in Issue 1 of Sonic the Comic and are based off of the enemies of the same name from Sonic the Hedgehog on the Sega Mega Drive.
