Synopsis: Mobile Suit Gundam Thunderbolt

The Universal Century began when humans migrated to outer space, and in the year UC0079, the Side 3 colonies declared independence as the Principality of Zeon, sparking a war with the Earth Federation. The conflict has been ongoing for almost a year, with intense fighting in the Thunderbolt sector—a region filled with remnants of destroyed warships and space colonies—as the Earth Federation seeks to reclaim Zeon-controlled territory.
