Technology & Combat Characteristics
A security Gunpla deployed by the GBN administration, it is a version of the GBN-Guard Frame equipped with Gundam-type armor. This additional armor uses a newly developed armor system known as "Gain Armor", which has special units built into it that can change the qualities of the Gunpla or boost its capabilities. The characteristics of the GBN-Base Gundam have been boosted to match the capabilities of the RX-78-2 Gundam, dramatically improving its performance.
The GBN-Base Gundam is mainly used by Game Master-class members and other similar high-class GBN administration members to directly intervene in GBN, and is capable of superhuman feats and strengths as displayed by Amuro Ray in the Mobile Suit Gundam anime, impressing and exciting all Divers. Beside this RX-78 type, there exist other Gain Armors compatible with the GBN-Guard Frame that are based on various Gundam-types and rival Mobile suits from different series.
