The MS-14A Gelgoog is a fictional mobile suit from Kidou Senshi Gundam, serving as one of the Principality of Zeon's late-war mass-production units. It appears as a powerful successor to earlier Zeon mobile suits, designed to rival the Earth Federation's Gundam-type machines. In the series, it represents Zeon's advanced military technology and desperate push to regain battlefield superiority near the end of the One Year War. The Gelgoog is often remembered as a symbol of Zeon's final, formidable efforts.
