ZZ Gundam makes the move to HGUC! To preserve the outstanding detail and proportions, transforming is accomplished via interchangeable parts. The 'Double-Zeta' can be transformed between Core Fighter, Core Top, Core Base, and G Fortress modes. As part of its arsenal, the ZZ Gundam features a Double Beam Rifle, two Hyper Beam Sabers, and Missile Pods. When displaying it in G Fortress Mode, part of the frame is used as a base. This piece also holds parts which are not used when in certain modes. Foil stickers are also provided.
