RGZ-91 Re-GZ
An attempt by Anaheim Electronics to cheapen and simplify the Zeta Plus Mobile Suit - resulting in the Refined Gundam Zeta, a new MS deployed by the Earth Federation Space Forces Londo Bell fleet.
Omitting the transformation mechanism in favor of a backpack that enabled a simulated Wave Rider Mode, it ultimately didn't perform as expected, and the data obtained from the two prototypes - one piloted by Amuro Ray and Chan Agi - helped to create the first mass production transformable MS of the Federation - the ReZEL.
