Well recently the vehicle sets (which are expensive, not gonna lie) have some interesting action features. Rockoh's wings flipped down and a trigger on the side shot the Midaks; Jetrax's engines folded out and its cockpit opened (if you consider that a feature); Axalara's landing gear could retract, its back claws/wings/whatever extended, and the front opened to reveal Midaks; Thornatus' front wheels could extend and you could open its cockpit (again, if you consider that a feature). The first three had gear systems, some rather complex. So they hadn't completely died yet.
