[Brainchild]

I don't know about that. I really like the Go-Buster toys; the individual mechs look great, as you said. But I have to disagree about the combined forms. They all scream bulky and powerful, which is something that certain mechs and Megazords have trouble doing. Gokai Oh is a shining example of everything that GoBuster Oh fixes. The vehicles were so simple that they served no purpose other than combining into Gokai Oh (or being left off, for that matter). Here, they have individual weight and they make the combined mode have more value than just being the Sentai's only robot.
