Moguera whose name is an acronym for Mobile Operation Godzilla Universal Expert Robot Aero-type (MOGUERA), debuted in the Godzilla series in the 1994 film Godzilla vs. SpaceGodzilla. In the Heisei Godzilla continuity, MOGUERA was constructed by G-Force alongside Mechagodzilla and completed following the latter's defeat. Designed to accomplish what its predecessor had come so close to doing—destroying Godzilla—MOGUERA's first action came not against Godzilla, but a crystalline anomaly that was sighted approaching Earth. MOGUERA was launched to destroy the space creature, but was severely damaged and failed to halt its approach to Earth. MOGUERA was salvaged and repaired by G-Force, then deployed to Fukuoka to stop the space monster, now known as SpaceGodzilla, after it constructed its own fortress in the city. MOGUERA engaged SpaceGodzilla, and was joined by Godzilla, who sought to rescue his adopted son from his extraterrestrial clone. Together, MOGUERA and Godzilla were able to destroy SpaceGodzilla's power source in the Fukuoka Tower and finally destroy him, but MOGUERA was also obliterated in the process, leaving only Godzilla standing.
