Yeah, but I think the main selling point throughout is that the Guyvers and Zoalords can interact with their space habitats: the Advent Ship and Ark, respectively. So, for instance, you can suspend the Guyver on a clear-coloured beam to show him interacting with the ship's two navigation spheres, and when this happens LED lights flash on the walls of the Advent ship, like you saw in the comics, and the whole thing starts to rumble with special effect noises!
... because, because he just 'activated' it!
And the Ark ship only gets rock-and-rolling when you have all twelve Zoalords!
