The Psycho Gundam Mk-III is a gigantic Mobile Suit from the Gundam: The Battle Master video game. It was initially piloted by Maria Nichols.

Technology & Combat Characteristics

Very little is known about the Psycho Gundam Mk-III. It is unclear if its cockpit is located in the head, or if it has a transformation mechanism and psycommu system like its predecessors. Its armament include multiple mega particle guns on the shoulders, legs and chest, and large beam swords on both arms.


  • Scattering Mega Particle Beam Gun
  • Pulse Beam Gun
  • 3-barrel Beam Gun
  • Beam Gun
  • Large Beam Sword


The Psycho Gundam Mk-III was secretly developed by the Nomad Council military and piloted by Maria Nichols, a test subject for the extrasensory virus. However, it was stolen by Maria during a test. Maria, piloting the Psycho Gundam Mk-III, serves as the final boss of Gundam: The Battle Master.

In Gundam: The Battle Master 2, Gloria Chamberlain encounters the Psycho Gundam Mk-III, piloted by Maria Nichols to block her way to Pixie. Despite its overwhelming firepower, Gloria managed to beat it single-handedly while killing her in battle.


Notes & Trivia

  • In Gundam Battle Assault, it is piloted by Valder Farkill and in the following game, Gundam Battle Assault 2, Ulube Ishikawa pilots it.
  • Its model number, MRX-012, was only stated in the 2009 edition of MS Encyclopedia. However, the 2013 edition no longer mentions it.
  • Psycho Gundam Mk-III makes it return in SD Gundam G Generation Genesis 15 years after its last appearance in G Generation F.I.F.
    • When using its Large Beam Saber in this game, the slightly jerky animation after making contact is a callback to its multi-hit property in Gundam Battle Assault.
  • Since the Battle Master series takes place in an original setting, the Psycho Gundam Mk-III's canoncity in the Universal Century timeline is unclear. Though the designation of MRX-013-3 Psycho Gundam Mk-IV G-Doors seems to hint at its existence.
