The MSZ-006 Zeta Gundam, the titular mobile suit in Mobile Suit Zeta Gundam, and prominently featured in the sequel series Mobile Suit Gundam ZZ, represents a groundbreaking achievement in mobile suit development. It was conceived as part of Project Zeta, the third-generation mobile suit initiative initiated by Anaheim Electronics at the request of the AEUG. This revolutionary Transformable Mobile Suit (TMS) overcame challenges faced by its predecessor, the MSN-001 Delta Gundam, which experienced issues with its transformable movable frame.

Addressing the concerns, the design team drew inspiration from the successful movable frame of the RX-178 Gundam Mk-II. This adaptation, combined with the incorporation of Gundarium γ alloy armor—previously utilized in Anaheim's RMS-099 Rick Dias—resulted in the creation of the Zeta Gundam.

One of the defining features of the Zeta Gundam was its ability to transform into a cruising mode named "Wave Rider Mode." In this configuration, the Zeta Gundam assumed a wedge shape, strategically concentrating shockwaves generated during supersonic flight underneath the mobile suit. This unique design allowed it to ride the resulting wave, justifying the nomenclature. The Flying Armor mounted on the movable frame on its back played a crucial role in this transformation, offering protection from shockwaves and heat during atmospheric entry. Derived from data from the support vehicle of the same name, the Flying Armor could be replaced with alternate equipment, such as the Wing Binders for the Wave Shooter specification. This versatile mode served not only as an atmospheric entry solution but also as a sub-flight system for other mobile suits. The Zeta Gundam's transformative capabilities and innovative design marked a significant leap forward in mobile suit technology.
