The Zeta Gundam was capable of transforming into a cruising mode known as "Wave Rider Mode". In this form, the Zeta Gundam adopted a wedge shape, concentrating the shockwave generated by supersonic flight underneath it and riding the resulting wave, hence its name. In this form, it was capable of entering the atmosphere without any optional equipment thanks to the Flying Armor mounted on the movable frame on its back, which protected it from shockwave and heat during atmospheric entry. The Flying Armor was based on data from the support vehicle of the same name, and could be replaced with other equipment, such as the Wing Binders for the Wave Shooter specification. The Wave Rider Mode could also function as a sub-flight system for other mobile suit.
