A mysterious machine discovered in the basement of Morgenroete.
Its structure is identical to the GAT-X105 Strike Gundam, but the electronic arrangement of the phase shift armor has been modified, resulting in a design that significantly reduces power consumption.
The left shoulder also bears the Morgenroete logo, with no OMNI logo, and the right shoulder bears AA (Archangel).
This machine is shrouded in mystery as it was never used and was stored in the basement of Morgenroete.
