GA-37 Grendizer

Grendizer, designed and animated by Go Nagi, is probably one of the most recognizible robots for diecast robot collectors.  Black and red adorned with harkens on the shoulders a.k.a killer knives.

Fists shoot, the head can pose, legs bend, and then you have a 90% metal toy.  On top of a solid design is an optional Space Saucer ship.  Grendizer fits inside this jet to battle evil doers and win the day.
