1/6 SSC Batman Classic Sixth Scale Figure

[bat1975]

It's a body of their own design. There's no name for it like other bodies that I am aware of (like TrueType, Prometheus, etc).

It's this body linked below. It has been used for this Batman, Magneto, Thor, Superman and Luke Cage so far. Similar to what's been used with Punisher, Cyclops, The Flash etc but with larger arms and only 90degree elbow bends and no bicep swivel.
