It's a Theta Plus style made from the HG ZZ Gundam. The "MSZ-010A1 Theta Plus" is set to be the flagship machine that is the culmination of the Theta Project, which includes the ZZ Gundam. It appears in the manga "Mobile Suit Moon Gundam" as the machine deployed to Londo Bell. For many years, one of my goals was to make a Theta Plus from the HG ZZ Gundam. And finally, I achieved it the other day. I've been modifying the HG ZZ Gundam in various places. I modified the duct part on the side of the head. The antennas were reduced from four to two. The high mega cannon on the forehead is set to be omitted, so I used plastic sheet to cover it.
