Ryuusei no Rockman Tribe

This series continues the story from the second video game, centering on the lost continent of Mu, an ancient civilization that disappeared long ago. Some of its remnants are now known as UMAs, mythical creatures that begin fusing with humans to locate powerful artifacts called ooparts, which are believed to hold the key to reviving Mu. Subaru and War-Rock face various strange foes before meeting Doctor Orihime, who tasks them with retrieving the ooparts to prevent the UMAs from succeeding. Rockman utilizes these artifacts to transform into different forms, such as Thunder Berserk, Fire Dinosaur, and Green Shinobi.
