I watched the Zaku II anime and decided to build a Gunpla for the first time in a while. Compared to the first generation Zaku, the legs are sculpted to be too thin, but considering the vernier thrusters and such, this interpretation is acceptable, and the fact that the leg parts are the same for both sides might be rational when considering its use as a weapon. I just snapped it together, painted it with clear red and clear green, and added some weathering and silver dry brushing for a quick and easy box art-style build.
