Its really nice from people to improve toys with that kind of actions, really appreciate it. Still i can't get why for example Invisible or Bumblebee can have been designed like Unique Toys Cy-kill, i mean the hands. I mean in neither case affects to transformation, or in their alt mode, i don't found a pic of them sorry. Its just the same system but instead of leaving a hollow arm, just close the little tape on the down part, resulting in a nice arm. Cheap and easy.
