Battle with Spider-Man
Six worked at a carnival as a member of the Freaks, a group of circus freaks. When Six and the Freaks fell under the control of the sorcerer Moondark, they were forced to battle Spider-Man. Six and the Freaks were later seen in a fight against the criminals Hammer and Anvil.
Note: Six was first seen in a picture in Marvel Team-Up #91 (1980) before he made his first full appearance years later in Marvel Tales Issue #256 in which the Marvel Team up story was reprinted and a new story was added, starring among others, Six.
