From 1000toys. The prototype build of the male type Synthetic Human was developed by TOA Heavy Industries for special operations. For the first time in 1/12-scale, this is not a mere downsized version of the original 1/6-Scale TOA Heavy Industries Synthetic Human, but a more brushed up version with articulation, gimmick and outline optimized to fit the 1/12-scale body size. If you are new to the world of TOA Heavy Industries, now is your time to jump in.
