This base defense-spec unit was deployed on the planet Pezun in the GQuuuuuuX world line, and I created it with the Hakuji equipment for close-combat, but also for shooting duels with the shield and shoulder-mounted missile pods.
To achieve this, I painted the Rick Dom to look like a Pezun Dowadge.
The bottom of the cross mono-eye rail was filled with putty to create an inverted T shape.
To accommodate the Hakuji equipment, I did not attach a beam saber rack, but instead connected the missile pod from the Origin GM.
The left chest armor was also filled with putty.
