Release Date: February 2026

Price: 23,100 Yen

The Prototype Rick Dias, also known as the Prototype γ (Gamma) Gundam, makes its long-awaited debut in the Ka Signature lineup! An AEUG prototype mobile suit, it served as the forerunner of the Rick Dias and was used to test the revolutionary Gundarium γ Alloy. 

Developed by Anaheim Electronics with a focus on agile combat performance, it incorporated Earth Federation Forces’ movable frame technology to cut down on time and costs. Its distinct features include a Dom-type mono-eye sensor, sub mono-eye camera, large backpack with thruster binders that double as shields, torso-mounted cockpit, hyper beam sabers, and clay bazooka armament.
