The RGZ-91 Re-GZ (Refined Gundam Zeta) is a transformable mobile suit based on the MSZ-006R Zeta Plus R. It was introduced in the anime movie Mobile Suit Gundam: Char's Counterattack and had a cameo in the OVA series Mobile Suit Gundam Unicorn.

The BWS was developed with reference to subflight systems such as the Base Jabber and FXA-05D G-Defenser, and in particular, the MSZ-006R Zeta Plus R (a machine with a large detacheable backpack) from the Zeta Plus series. The BWS is armed with additional beam weapons and propellant tanks. As the Re-GZ was developed during a time where large-scale battles did not occur and it was more expensive than other MS, so only one prototype was built. Despite the Re-GZ boasting high specifications that outclassed other mass-production machines, it struggled against Neo Zeon's Newtype-use mobile suits in U.C.0093 due to a lack of Psycommu weapons.
