Blockhead Bill

The elderly father of Mighty the Armadillo, Blockhead Bill 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, who he rides like a horse and uses as his main form of attack, he 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 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 he 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 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 he 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.

Notes: Unlike Archie Comics, Blockhead Bill is one of only two Sonic the Comic characters created as a family member for a Sega-created character. The other is Charmy's mother, who was not given a first name. (Tails' family is mentioned but never named or shown).

It has been said online by co-creator Nigel Kitching that Bill and Max were "probably having a homosexual relationship".
