Q Transformers: Kaettekita Convoy no Nazo

Second season of Q Transformers: Kaettekita Convoy no Nazo.

Released theatrically as part of a triple feature of animated films based on Takara properties. The other two short movies included were "Super Doll Licca-chan" and "Microman". Due to the relatively late theatrical release, the episode was not included on Pioneer's Japanese DVD box set of Beast Wars Metals.

An evil race of transforming robots known as the Destronger make their appearance known by invading a world exposition in New York and abducting Professor Onishi, a renowned scientist. The professor's son Yuuki befriends Fire Convoy and the heroic Cybertron forces, who will stop at nothing to rescue the professor and protect Earth from the wrath of Gigatron and his Destron henchmen.

A huge black hole is about to swallow the entire universe, including the Transformers' home planet Cybertron.. While Galaxy Convoy and the others search for a solution, the Transformers escape from the collapsing planet and infiltrate Earth as "robots in disguise"...Galaxy Convoy encounters Vector Prime and learns of the existence of "Planet Force", an ancient relic capable of resetting entire planets, believed to have been lost thousands of years ago with Cybertronian explorers who failed to build a space bridge to the edge of the universe. Thus, Galaxy Convoy and the Cybertron warriors he leads embark on a grand adventure across the vast universe in order to find the Planet Force and awaken the ancient warrior Primus to save the universe. However, Master Megatron and his underlings plot to control the entire universe by acquiring this power, and they relentlessly obstruct Galaxy Convoy and his friends...Will Galaxy Convoy and his friends be able to safely obtain Planet Force? Note: The international version considers this series a sequel to Micron Densetsu (Armada) and Superlink (Energon), featuring references to characters and events from the two, as well as an additional scene in episode 51 linking the three. Note: The US release initially combined episodes 1 and 2 into one, before ultimately airing a dubbed version of episode 2 as episode 52.
