During the Gryps War, the Earth Federation Forces and the Titans developed several experimental transformable mobile suits/mobile armors and conducted field tests by placing them into actual combat. One of the more well-known designs was the RX-139 Hambrabi, and it was unique in several respects. One of the most visible features was its five monoeye sensors placed all over its body, enabling the pilot to more easily locate and track targets in both mobile suit and mobile armor mode. Its body also mounted several wing-like stabilizers, giving the Hambrabi high agility and maneuverability in mobile armor mode similar to that of a space fighter. In addition to being armed with a pair of beam guns and the RX-110 Gabthley‘s Feyadeen rifle, the Hambrabi could also carry a sea serpent, a wire-guided grappling weapon used to deliver crippling electrical shocks to enemy mobile suits. The Hambrabi was most famously used by Yazan Gable, a brutal Titans pilot who was defeated at the end of the war and barely survived thanks to his cockpit’s escape pod.
