Factor Six (Joint Venture)

Factor Three was a team of evil mutants fought and defeated by Professor X and the original X-Men. This is the Joint Venture Universe version of the organization.

Roster
Factor Six was the first terrorist organization comprised entirely of mutants, a precursor to the Brotherhood of Mutant LIberation. Indeed, most of its members would go on to be founding members of the latter organization.

As the name implies, Factor Six was comprised of six members. Each member of Factor Six (save Banshee, the last person to join) was contacted by a mysterious being known only as The Mutant Master, and enlisted with promises of greater power and their fondest wish granted: Banshee, the last 'recruit' was offered to Factor Six by his younger brother, Black Tom Cassidy.
 * Jason Wyngarde, the illusionist known as Mastermind, was promised the opportunity to get his daughters back.
 * Carmela Unuscione was promised revenge on the murderers of her father, who had died when he lost control of his powers while fighting an angry mob.
 * Kevin Sydney, the shapeshifter Morph, was promised a cure to an unstable element within his mutation that was slowly killing him.
 * Frederick J. Dukes, a strongman whose powers earned him nothing but scorn, derision, and cruelty from others, was saved from the brink of suicide and promised the opportunity to avenge himself on those who had wronged him.
 * and Porter Telford, the teleporter known as Vanisher, was simply offered a grand sum of money.
