Takara is focusing on 1 things for the train bots. Realistic trains and cartoon accurate robot modes. If you want Raiden. Go with Moon Studios. Takara will be my bots and Moon Studios my Raiden
Sam (a 3D Designer and now with Ties to MMC) made a good thread about this (and a good discussion with Bobby Skullface on his Patreon).
I'm not against this philosophy. In fact I've more or less adopted it for Fanstoys' combiner teams. Their Stunticons and Aerialbots are so great individually that honestly I don't care all that much how the combine modes turn out. But even with that in mind, Takara's trainbots are too small to scale individually, too. They look great, I just have nowhere for 'em to go.
