"Engine Fusion! Engine-O Tune up! Go-on!"
Engine Gattai Engine-O (炎神合体エンジンオー Enjin Gattai Enjin'ō) is formed when Speedor, Buson and Bear RV combine. Referred to as the "King of Engines", this mech is armed with the Go-On Sword (ゴーオンソード Gōon Sōdo), which is stored within on of Buson's compartment folded up to resemble an Engine Soul, and the V Shield (Ｖシールド Bui Shīrudo), which is formed from Bear RV's undercarriage.
Engine-O's main finisher is the Go-On Grand Prix (ゴーオングランプリ Gōon Guran Puri), where Engine-O charges at the enemy Banki at mach speed with sword in hand, landing the deathblow as it moves past, with the background forming a checker flag.
With GunBir-O and Seikuu-O, Engine-O can perform the following attacks: the Go-Onger Storm (ゴーオンジャーストーム Gōonjā Sutōmu), the Triple Punch (トリプルパンチ Toripuru Panchi), and the Grand Prix Festival (グランプリフェスティバル Guran Puri Fesutibaru).
While Engine-O is composed primarily of Speedor, Bus-on, and Bear RV, the combination can receive power-ups by performing "Engine Armaments" (炎神武装 Enjin Busō)
With Birca, Engine-O becomes Engine-O Birca (エンジンオーバルカ Enjin'ō Baruka), using the Bircutter in its Bircutter Slash (バルカッタースラッシュ Barukattā Surasshu) attack.
With Gunpherd, Engine-O becomes Engine-O Gunpherd (エンジンオーガンパード Enjin'ō Ganpādo), using the Gunpherd Gun in its Gunpherd Gunfire (ガンパードガンファイヤー Ganpādo Ganfaiyā).

With Jetras and Toripter at the same time, Engine-O becomes Engine-O Jetripter (エンジンオージェットリプター Enjin'ō Jettoriputā), using its right arm's Toripter Rotor (トリプターローター Toriputā Rōtā) for defensive/offensive attacks while its left arm is used as the Jetras Bow (ジェットラスボウ Jettorasu Bō) in the Jetori Bullseye (ジェットリブルズアイ Jettori Burūzuai) attack.
When armed with Jetras only, Engine-Oh becomes Engine-O Jetras (エンジンオージェットラス Enjin'ō Jettorasu). Its finisher is the Go-On Bullseye (ゴーオンブルズアイ Gōon Burūzuai), where Engine-O fires the Go-On Sword with Jetras' bow.

Shinkenger vs. Go-Onger
When GokaiOh and Gosei Great faced the Black Cross Colossus, the mecha of the first 33 Super Sentai, including Engine-O which possibly manifested from a toy version like DaiDenzin and the Variblune, appeared to back them up. When the Black Cross Colossus summoned several giant villains to oppose them, Engine-O fought alongside Dairen'oh and RV Robo to destroy Crime Minister Yogoshimacritein. After all the giant villains were destroyed, all 35 mecha weakened Black Cross Colossus with a combined attack before GokaiOh combined with the Variblune to become Goren GokaiOh which destroyed the Black Cross Colossus with the Gokai Hurricane: Cassiopeia finisher. With the battle won, the 33 past Super Sentai mecha vanished.
Zyuohger vs. Ninninger
Representing Go-Onger, Engine-O G12 appeared among manifestations of the first 38 Super Sentai's mecha that granted Wild Tousai Shuriken King the power to perform the Zyuoh Ninnin Super Sentai Burst which destroyed the titanic Gillmarda.
