Siam

They appear as two humanoid figures, one male and one female, horrifically fused together and tied with a series of bondage gear and straps. The male side is the attack side, and his arms are morphed into huge, club-like appendages much like that of the Closer and Mandarin  monsters. He also appears to be wearing some sort of chest armor. The female is fused into the male's back, with her hands tied above her head and thereby the male's as well, and her legs also tied, dangling uselessly behind them.
