Super X (Heisei)
The Capital Defense Mobile Fortress Super X (首都防衛移動要塞 スーパーX, Shuto Bōei Idō Yōsai Sūpā Ekkusu) is one of the most iconic, influential, and technically formidable human war machines in the history of the Godzilla franchise, debuting in Toho's landmark reboot *The Return of Godzilla* (1984). Conceived in absolute secrecy by the Japan Ground Self-Defense Force (JXSDF) as a mobile command bunker designed to preserve governmental continuity during nuclear war or catastrophic crises, the Super X was pressed into emergency service when Godzilla marched inexorably toward downtown Tokyo. Possessing a distinctive rounded turtle-shell silhouette, vertical takeoff and landing (VTOL) omnidirectional propulsion that allowed it to hover gracefully through claustrophobic skyscraper corridors, and advanced heat-shielded titanium-ceramic armor capable of withstanding direct atomic breath blasts, the Super X achieved what no human weapon before it had: it defeated Godzilla in single combat. By launching precision cadmium rockets directly into the monster's open maw to absorb neutrons and shut down his internal nuclear reactor, the fortress induced cardiac arrest and rendered the leviathan clinically dead, until an unpredictable atmospheric nuclear detonation reversed the outcome.
