The MSZ-010 ZZ Gundam (pronounced as "Double Zeta" and codenamed "θ Gundam" or "Theta Gundam") is the titular mobile suit of Mobile Suit ZZ Gundam.
The unit is also transformable, turning into its G-Fortress mode, like its predecessor MSZ-006 Zeta Gundam, equipped with the Core Block System like the RX-78-2, and armed with heavy beam weaponry. However, its highly destructive arsenal needs a high output of power, draining its power especially when it fires its Hyper Mega Cannon.
This mobile suit is mainly piloted by Judau Ashta.
