Cyborg Ninja Papercraft

Cyborg Ninja is an alter-ego assumed by several invidivuals that wore exoskeleton (or ninja suits) to conceal their true identities. The powerful exo-skeletons that the Ninja's wear is made by the Tokugawa Heavy Industries. I remember having a hard time defeating this Cyborg when I played Metal Gear Solid many years back. It is available in two sizes: 21 & 31 cm.
