Description:

Transformers Go! is a Japanese exclusive sequel to Transformers: Prime - Beast Hunters. There are two chapters: Samurai and Shinobi. Both, however, share the same basic plot. Two humans, one descended from a line of samurai and one from ninjas, encounter the Predacons who are attempting to steal the legendiscs-powerful ancient artifacts-to revive their leader, Dragotron. However, the discs summon two teams of Autobot Swordbots, each corresponding to the human partner's ancestry. From then on, with the help of Optimus Prime, they combat the Predacons while attempting to retrieve all the legendiscs.
