Doubledealer
Doubledealer is unique among Transformers as he holds a place in both the Autobot and Decepticon armies. The truth, however, is that this ruthless mechanoid is a mercenary loyal only to whomever is paying him, and then only if no better offer catches his eye. At times, even his own partners are unaware of all of Doubledealer's duplicitous dealings. His skills and power make him a valuable asset to both sides, but neither really trust him as far as they could throw a Guardian robot.
Doubledealer is also almost unique among Powermasters in possessing two binary bonded partners, Knok and Skar, a trait shared only with one version of Overlord.
Sometimes he goes by the separate names Double and Dealer as well and sometimes his name is spelled Double Dealer.
