see I dont quite follow what you guys are talking about. if i were to guess, you wanted MY hands to fit into the "power of the primes" series combiner hands and feet just like titan masters do? My hands are currently abit too big to fit into the titan master slots, and they cannot be shrinked any further without sacrificing finger articulation. Likewise, my hands are not big enough to making a cavity to hold a titan master as well, at least not without sacrificing finger articulation. Sorry.
