MS-14C Gelgoog Cannon is a fictional mobile suit from the Mobile Suit Variations (MSV) side materials of the Gundam franchise. It is a fire-support variant of the Gelgoog, equipped with a large cannon for long-range combat and battlefield suppression. Rather than a character with a personality, it serves as a specialized military machine in the setting, representing Zeon’s efforts to adapt the Gelgoog design for heavier artillery support and tactical flexibility.
