As I mentioned on twitter my favourite bit is that pilots contain batteries, I think, when they are put in the vehicles they power the whole process. Which if Takara had put this under Transformers branding would have made these Combiner Powermasters. But Powermasters that actually did power the transformation.
Also the powermasters are just cute. Also also putting the battery changes the eyes from a dormant blue to an Active yellow with blue pupil.
