Brainulo is a time-traveling super-villain. He has an over-sized cranium and an under-developed body, eventually requiring the aid of a motorized chair to move around. Brainulo claimed to be from 1,000 years in the future, and that he had been stranded in the 20th century by Jonas Venture Sr. This caused him to hate Jonas, resulting in Brainulo's agreeing to join Scaramantula's Fraternity of Torment.
