The ZZII (pronounced "Double Z-Two") is a Gunpla that appears in Gundam Build Fighters Try Island Wars and is based on the MSZ-008 ZII. It is built and piloted by Minato Sakai.

Created by Minato to defeat the MSZ-006LGT Lightning Zeta Gundam which is built by his rival Yuuma Kousaka, the ZZII is based on the MSZ-008 ZII and is designed as a high speed, high mobility unit.[1][2] With this Gunpla, Minato also managed to achieved a perfect balance between two opposing elements: keeping the unit's weight down and at the same time enhance its structure.[2] Similar to his previous Gunpla, the 最強機動 Gundam Tryon 3, the ZZII also has high attack power, but unlike Tryon 3, the ZZII achieved this through high level of energy/particle convergence.[2] The ZZII is armed with a Hyper Long Rifle, a Center HM Cannon, a pair of Beam Bazookas, a pair of Beam Sabers and two Head Vulcans.[2] The Hyper Long Rifle and Beam Sabers are improved versions of the ZII's Mega Beam Rifle and Beam Sabers respectively.[2] The Center HM Cannon and Beam Bazookas can be used together in a devastating attack known as 'Tri Burst'.[2] The ZZII retains the transformation ability of the ZII, and has a pair of Wing Shields on its back to enhance the Waverider mode's dogfighting capability.
