Merris' Mech is a Regular Army vehicle piloted by its titular owner. It is introduced in Metal Slug: Commander.
Information
This machine is a hovering, humanoid mech with cables connected to its arms. Its torso is an exposed cockpit where the pilot controls by grabbing and shifting its handles. The mech has two greatswords that also function as laser cannons. These are charged by orange energy transferred by the mech and in a straight line or as a wave.
Merris continues to fight on foot should her mech be destroyed and can summon another one once her special is activated. If this skill is at Lv. 2, then her destroyed mech will leave a greatsword 30% of its HP as a shield.
The mech provides defense to both Merris and her allies. The mech's Cerberus Tech allows it to gain up to 30% DEF when losing HP.
