Technology & Combat Characteristics
A variant of the Core Gundam docked with the Mars Armor. It specializes in close combat and is equipped with various melee weapons such as the Slash Blades. The various blades can be combined to form powerful large swords, allowing the Gunpla to deal with one-to-one-combat, one to many battle, and against enemies that are much larger. Acceleration devices are also built into the Mars Armor, greatly enhancing Marsfour Gundam's instantaneous force. With its nimble attacks and maneuvers, the Gunpla can slice through various enemies.
