Engine Gattai Engine-O is formed when Speedor, Buson and Bear RV combine. Referred to as the "King of Engines". It's main finisher is Go-on Grand Prix. Either or both of Engine-O's arms can fold up to accommodate other Engines (Birca for Bircutter Slash, Gunpherd for Gunpherd Gunfire, Toripter and Jetras for Toriptor Rotor and Jetori Bullseye) for use as armament.
