Blockhead Bill

Blockhead Bill is the elderly father of Mighty the Armadillo. He is a somewhat senile former crimefighter who keeps mistaking random people for his old enemies. He is kept partly under control by his partner Society Max, who uses a special formula to change into a giant T-rex like monster, and whom Bill rides like a horse and uses as his main form of attack. Bill also uses weapon consisting of many gold metal balls on a hoop of rope, which he spins and hits enemies with. He does not seem to have Mighty's and Gobo's trade-mark super-strength.

Blockhead Bill mistook Sonic the Hedgehog for his old enemy the Crimson Cobra (who would appear later in a Chaotix story) was the plot of the Sonic story "Back In The Special Zone" (STC #134, Blockhead Bill's debut) which was solely about Bill, riding Society Max in his large dinosaur form, attacking a confused Sonic who had been called back to the Special Zone by the Chaotix (Sonic had previously spent time there before and stayed with the Chaotix) instead of poisoning the water supply. He was then a major part of the following story "Roots" (STC 135 - 138) where he was under the thrall of the story's main enemy, Root, who used both Bill and Society Max as minions controlled by controlling them with 'Mind Roots'. Bill and Max had been captured and taken over by Root while searching The Mandrake Swamp, where Root dwelt, for the root that Max uses to transform, though he and Max had less of a role as the story progressed, and Sonic fought the Chaotix. When Bill and Max did attack, Sonic defeated Max by tickling his stomach, making Bill furious at him (he hadn't told Bill he was ticklish). When Root was defeated, Bill and Max regained their right minds and were not seen again.
