Built 2 out of the 3 Black Tri Stars which is a special unit of the Zeon forces. All three kits share the same main kit with different weapon load-outs.
Gaia is armed with a bazooka and multiple bazooka cartridges to enable him to fire continuously.
This 2nd time that I started building Gundam Plastic kits I have now a bigger appreciation to the so called villains and the grunt suits of the series instead of the main mobile suits
