I realized the deadline is approaching so I'm posting an old work!
I basically build the Build series Gunpla based on my fantasy that they are "MS that actually existed in the Universal Century."
The Lightning Gundam is based on the Re-GZ (I think).
In my mind, the story goes like this: "A revived Kamille joins Londo Bell. The Federation Army refuses to deploy the Z Gundam, so Bright negotiates with Anaheim and acquires the high-performance Re-GZ."
The paint is minimal.
