This figure was done over the Alpha Blanx figure buck. He is 4 inches tall. He was heated and stretched, then ground down and sculpted over to get the very thin body type. This figure was shown at the "Son of Monsterpalooza" show in Burbank, CA. October 2012.
There are more pics of him and many other at the Go Native Toys website
