Keychain arm compatibility
Hi, I'm really excited about the new Dr. DOOM minifigures, specially the comic book one. I think it it's a dope minifigure and I thought that the arms of the draconic warrior could be a great improvement.
I know that the Keychain miniatures are different from the helmet/hair, head, torso and hips but I'm clueless about the arms, so my question is:
Should I go cheap and change the arms or sadly the Keychain arms are not compatible and I'll have to go to bricklink and find the normal draconian warrior.
Tnx!
