The RX-77-2 Guncannon is a prototype mobile suit featured in the anime series 'Mobile Suit Gundam' (Kidou Senshi Gundam). It is one of the Earth Federation's earliest mass-production mobile suits, designed for long-range support and artillery. Piloted by Kai Shiden and occasionally Hayato Kobayashi, the Guncannon plays a vital supporting role in the White Base crew's battles against Zeon forces. Its distinctive red armor, powerful shoulder cannons, and versatility make it a key asset throughout the series.
