The RGM-90C GM Cannon IV was made at the same time as the Jegan but of the two, the GM IV is the superior mobile suit. Based on the Gundam Mk. III, it’s a masterpiece of mobile suit engineering but was found to be too expensive to be practical as a general purpose mobile suit. For Team Reconcile’s use, the mobile suits are outfitted with extra armor and a mega-beam cannon. As the RGM-90C GM Cannon IV, it serves as a high performance support machine for the team.
