>>10388420The big feature of Rook is that the cannon barrels that are his hands are 5mm compatible. Which lets you do all kids of goofy shit, but mostly hulk hands with the HFGs.
Rook boasts better articulation than most of the line.
He has the ball jointed neck and shoulders and hips like normal.
And the waist, bicep, and thigh swivels like normal.
Even has the 90 degree hinges at the elbows and knees.
What sets him apart is having butterfly joints in his shoulders and ankle tilts. I'm not sure any other mold from that year had ankles.
