The MSZ-010 ΖΖ Gundam (aka ΖΖ Gundam, ZZ, MSZ-010; pronounced "Double Zeta") is the titular mobile suit of the anime Mobile Suit Gundam ZZ. It is piloted by Judau Ashta.

The ΖΖ is a transformable mobile suit, capable of becoming the mobile armor G-Fortress. The G-Fortress can separate into two flight-capable components, called the Core Top and Core Base. The Core Base is operated by the ΖΖ's Neo Core Fighter. Unlike the Ζ Gundam's Waverider mode, the G-Fortress is not capable of unassisted re-entry. The suit is also equipped with a bio-sensor, similar to the one found in the MSZ-006 Zeta Gundam.[1]

In terms of weaponry the ΖΖ features a large array of powerful beam weaponry. This includes two hyper beam sabers which are also usable as beam cannons, a double beam rifle, a 21-tube missile launcher installed on the backpack, and a high mega cannon on the forehead.

While the ΖΖ Gundam has a very destructive arsenal, the weapons systems require a high level of energy. As a result the ΖΖ often found itself almost completely drained of power after using its high mega cannon. In addition, its complicated construction and transformation systems made it somewhat structurally weak. These problems were eventually corrected with the MSZ-010S Enhanced ZZ Gundam and its massive final upgrade FA-010S Full Armor ZZ Gundam.
