RX-78GP03S Gundam "Dendrobium Stamen"

The Dendrobium was composed of two parts, the mobile armor section Orchis and the RX-78GP03S Gundam Dendrobium Stamen, a mobile suit that controlled the entire mobile armor. The Stamen had the ability to split from the armor section for independent action against enemy units. Operating as a mobile suit, GP03S carried a folding shield and beam rifle as standard armament, and special folding bazookas could be carried in place of either the shield or rifle. The traditional twin head vulcans were removed; the space thus freed was used to install more advanced avionics and sensor systems.

The Stamen also featured the panoramic cockpit and linear chair initially used in the RX-78 NT1, allowing its operator a full view of the battlefield. Originally a core fighter version was used (Gundam Evolve 4). However, it was changed to the current setting because if ever the GP03 had faced a foe so powerful that it could destroy the Orchis unit, the Stamen unit would not stand a chance and should not continue battle. Therefore, there was no need for 2 escaping devices since the Stamen itself was considered to be used for escape purposes. In addition, the wing binders on the sides of the GP03S both increased the maneuverability of the unit and protected the interface ports for the Orchis. A set of extendable waldo arms used to retrieve weapons from the weapon racks were concealed in the forearms of the GP03S.
