Head - B.A.T. v3 (modified with epoxy putty)
Neck - B.A.T. v4
Torso - B.A.T. v4 (modified with epoxy putty)
Upper Arms - B.A.T. v4
Lower Left Arm - B.A.T. v3
Waist - Sand Viper v1
Legs - B.A.T. v3 (modified with epoxy putty/various parts)

I wanted to make a custom B.A.T. to look like the original figure from 1986. I modified the B.A.T.'s (v3) head with epoxy putty.

For his torso, I dremeled and used epoxy putty on a B.A.T. v4 torso. For the legs, I used B.A.T. v3 and used exopy putty, a gun holtser and part of a black communication device.

I primed everything with flat white spray paint. For the weapon arm attachments, I customized them from the B.A.T. v4 attachments and the claw attachment from a 6" Batman figure's batcuffs.

A shout out goes to Cobra Command for most of this recipe.
