He has fought Daredevil and  Iron Man, and has teamed-up with other villains and groups such as  Maggia.

Power and Abilities
Despite not having any superhuman abilities, Potter is an expert Martial Artist and has vast amounts of strength. His costume was metal armor and his main offensive weapons were the knives and whirling blades that he could use either at melee range or fire with supreme accuracy.
