The NRX-055 Baund Doc is a transformable mobile armor introduced in the Mobile Suit Zeta Gundam anime. Pilots included Rosamia Badam, Gates Capa, and Jerid Messa (alongside instructor Loren Nakamoto).
Despite its apparent size and bulk, the Baund Doc's Mobile Armor mode was very fast and maneuverable thanks to multiple vernier thrusters and apogee motors. The Baund Doc can transform into an asymmetrical Mobile Suit mode, and this transformable mobile armor's armament consisted of a beam rifle, beam saber, a powerful diffuse mega particle cannon, arm claw and two leg claws.
A Newtype-use transformable mobile armor developed at the Titans' Augusta Newtype Laboratory, the Baund Doc was perhaps one of the strangest and most unique mobile weapons developed during the Gryps War. Two units were tested by Rosamia Badam and Gates Capa, with the former being taken up by Titans ace Jerid Messa after the unit had been abandoned, despite his lack of Newtype ability. Jerid would die piloting the Baund Doc, while Gates' unit was last seen drifting alongside the destroyed Dogosse Giar, its fate unknown.
