Well it's taken me a year or possibly even three watching off and on, but I've finished Victory so I've now been through the Takara Trilogy. I still stand by my original decision that Headmasters is the best one. I love the characters and variety in Victory, but having no real story to it prevents it being really enjoyable as a narrative. I thought when we had several episodes linked together with the whole Ginrai/Leo bit that it was about to pick up - but very strangely it came straight off the end of that run back into a handful of normal episodes, realised it was coming to an end and tacked on a two part finale out of the blue. Great momentum wasted. Suitably epic end though, very anime.
I also watched Zone just to finish the run because it's an extra on the last Victory disc, but I can't see that would have worked as a series. It'd be like the Transformers equivalent of Shadow of the Colossus with repeat to fade epic battles against the Decepticons' finest week in week out. I wonder if that was done like that to emphasise the smallness of the Micromasters - tiny Autobots versus whacking great huge Cons. I know the Japanese don't go much for toys of evil characters - but it seems odd the Autobots in Zone are based on toys but the Cons wouldn't have been available to buy at the time.
I rewatched Scramble City too just to be sure I'd seen it in context. Odd how Devvy gets a big chunk of that when it's really about the new teams and Metroplex.
