An attempt by Anaheim Electronics to cheapen and simplify the Zeta Plusmobile suit - resulting in the Refined Gundam Zeta. Omitting the transformation mechanic 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.
