I made an original Military and Police Zaku based on the Octopus Zaku from the Sieg-Axe world line.
The "MSN-01 Psycommu High Mobility Test Zaku" is a development MS from the Zeong that appears in MSV. It's nicknamed "Octopus Zaku" because it has eight legs for landing.
I fantasized about what would have happened if it had existed in the Sieg-Axe world line, and been developed based on the Zaku for testing the Alpha Psycommu, so I made this using the Military and Police Zaku.
Speaking of the Psycommu High Mobility Test Zaku, it has a lower body that looks like "The Rocket." I tried to recreate that using plastic sheet and plastic pipe.
