Don't hate or love the figure. I like the color and the fact that they used the interchangeable v1 arms.
Had they not used the v1 lower arms, parts and backpack, this figure would be a total failure.
So we know all the v1 parts exist except for the torso.
head - club
upper arms - whiteout/frostbite
lower arms - club
waist and legs - vipers
They could have used all these parts and just the v2 chest, but I guess it was not meant to be. I suppose the club wanted to give the bats a different look, and these parts wouldn't work with the metallic/gray color. So they had to use the parts they did.
