Technology & Combat Characteristics
A modified version of the prototype transformable mobile suit, Methuss, that is suitable for actual combat. Two of the beam sabers in each leg have been replaced with beam guns to increase its MA mode's firepower. It also has improve resistance to projectiles due to increased armor on several parts of its body such as the waist and knees, while its maneuverability is enhanced through the addition of wing-shaped flexible binders to both shoulders. These modifications caused the machine's weight to increase, leading to a slight drop in acceleration performance, but in exchange, its combat capabilities have been enhanced. Furthermore, a pair of grips have been added to its back so that its MA mode can function as a sub-flight system for other mobile suits.
- Beam Gun
- Like the normal Methuss, Avey Alva's unit has two forearm-mounted beam guns that flip forward in use, but it also has two more fixed beam guns in each leg.
- Beam Saber
- This machine is equipped with two beam sabers, one stored in each leg. Compared to the normal Methuss, Avey Alva's unit has four fewer beam sabers as they've been replaced by beam guns.
During the final battle at the Colony Laser, when it engaged the RX-136-1 Rakshasa, the upper and lower halves of its body were severed, but it still managed to inflict damage, giving Souichi Obino the opportunity to destroy the Rakshasa. Avey later escaped in an ejection pod, and the machine was abandoned.
