Metalhawk was exclusive to Japan, and his robot included die-cast metal components. Sparkabots have flint wheels which shoot sparks out of the rear of the vehicle mode. Firecons have flint wheels which shoot sparks out of their mouths. The engine is then placed into a special slot that enables the transformation into the robot mode. Darkwing and Dreadwind can combine their jet modes to form Dreadwing.
Pretenders have an outer shell which opens to reveal the robot inside.
The outer shells are listed in parenthesis. All of the Seacons except Snaptrap can transform into a weapon, to be used by Piranacon.
