Initially, I wanted to have a Rick Dom (GQ) carry a Hakuji, so I created it in the special colors of Ramba Ral, the Royal Guard who appeared at the end of the story with Princess Artesia. 
In my mind, I wanted to use the large Rick Dom so that the entire suit could be used as a shield if necessary, while incorporating technology from the Gelgoog and Gyan to greatly improve the thrust-to-weight ratio compared to previous suits.
