The RGZ-91 Re-GZ is a transformable mobile suit featured in Kidou Senshi Gundam: Gyakushuu no Char (Mobile Suit Gundam: Char's Counterattack). Rather than a human character, it is a mass-production successor concept to the Zeta Gundam, piloted notably by Rezin Schnyder? In the film, the Re-GZ serves as the Earth Federation's advanced prototype unit deployed against Char Aznable's Neo Zeon forces. It represents a practical, less complex evolution of variable mobile suit technology and supports the Federation's frontline efforts in the battle to stop Axis Drop.
