This is an alternative head for use with the original Transformers Headmaster Toy Scorponok, to make him more cartoon/comic accurate. It plugs in and stays in the headmaster socket, though his power readout isn't quite right. :)
This can be bought in Full Colour Sandstone, but I find the sandstone a bit rough on the socket, (but maybe you could sand down the plug a little.) so I recommend White polished.
