Transformers: Zone takes place some time after the events in Victory, and was meant to be another full-fledged series like it's predecessors, but the declining popularity of Transformers in Japan left it at only one episode long...which is truly a shame, because this the best animation of all Transformers! The story is rather simple, but that is not surprising since we only have one episode, so not much of a story is developed, but new characters are introduced at least. Right at the beginning, Star Saber vanishes on an exploding planet as three gigantic decepticons (Overlord, Menasor and Predaking, I think) arrogantly steal the planet's Zodiac energy. It seems that a mysterious new evil named Violenjiger has resurrected 'Nine Great Destron Generals' (which in itself is rather silly since Overlord is the only one of them who has actually had any commanding force), and when they appear on planet Zone to steal their energon as well, autobots are forced to go to earth to prevent them from destroying that planet as well.
