I made this when I first started brush painting.
I couldn't handle modifying the Gundam Mk-II from the HGUC Super Gundam, so I thought, "Why not combine it with the cool RG?" and while I was at it, I repainted it in the special colors of a boy who loves the Beam Magnum.
I realized after I started working on it that the G-Defenser from that time couldn't be attached to the RG without modification.
The homemade connection joint that I painstakingly fabricated from junk parts is the most frustrating part.
The G-Defenser & Flying Armor that was released by Premium Bandai a few years ago was good, but...
