■Unit
・★★★ Mass Production Type Psycho Gundam LV1 (General unit, ground/space uses, cost: 700)
※The above MS is eligible for the Monthly MS Bonus Unit.
■Mobile Suit Features
・General unit with cost of 700.
・This unit was developed under the leadership of the Titans,
with a goal of miniaturizing and mass-producing a Psycho Gundam.
・The Titans had plans for a new type of MS based on the Psycho Gundam Mk-II,
tailored especially for the ace pilot by removing the Psycommu System.
Instead, it is equipped with an Incom Unit.
・While it is downsized from the original Psycho Gundam Mk-II,
it boasted overwhelming firepower with no reduction in weaponry,
featuring Incom weapons capable of omni-directional attacks,
a large Mega Particle Cannon inheritedfrom the Psycho Gundam,
and a Hyper Beam Saber that can also be used as a ranged weapon.
・However, instead of being deployed as a decisive combat weapon against the AEUG,
it was dispatched near the lunar industrial city of Epsilon,
where it reportedly engaged the Full Armor Hyaku Shiki-Kai.
・Can be deployed both on the Ground and in Space.
