PMX-003 The O (PMX-003 ジ・Ｏ) is a heavy armored-class Mobile Suit that rivals the thruster capacity of its gigantic counterparts, Mobile Armors. Compared to Mobile Armors, The O's multi joint structure allows for a higher degree of mobility and agility to outclass most Mobile Suits. Since it's slow if forced to walk, The O shines in space combat and uses its mighty thrusters to move itself at all times. With simple armaments, it specializes in overpowering its enemies in close-ranged encounters.
