"Engine Fusion! GunBir-O Tune up! Go-on!" Engine Combination GunBir-O (炎神合体ガンバルオー Enjin Gattai Ganbaruō), referred to as "Another King of Engines", is formed when Gunpherd, Birca and Carrigator combine.
Its finishing attack is the GunBir Grand Prix (ガンバルグランプリ Ganbaru Guran Puri), where Carrigater first says "Herculean Strength Unrestricted" (剛力無制限 Gōriki Museigen), then GunBir-O performs a one-two slash attack with Gunpherd and Birca, then Carrigator participates by chomping onto the unfortunate Banki.
Its non-finisher techniques include Bircutter Storm (バルカッターストーム Barukattā Sutōmu) and Bircutter Wrist Returnバルカッター小手返し (Barukattā Kote Gaeshi). GunBir-O can also use the Gunpherd Gun and Bircutter Slash attacks. With Engine-O and SeiKuu-O, it can perform Go-Onger Storm, Triple Punch, and Grand Prix Festival.

Ren also makes Blaster Souls to use with the Handle Blasters.
With Jetras, GunBir-O becomes GunBir-O Jetras (ガンバルオージェットラス Ganbaruō Jettorasu), using Jetras's wings and the Bircutter in its Trabircutter Slash (トラバルカッタースラッシュ Torabarukattā Surasshu) attack.
With Toripter, GunBir-O becomes GunBir-O Toripter (ガンバルオートリプター Ganbaruō Toriputā), using the Gunpherd Gun and Toripter's turrets in its Toripgun Battery Out (トリプガンバタリオット Toripugan Batariotto).
- GunBir-O combines with Engine Gattai Engine-O and Engine Gattai SeiKuu-O to form Engine-O G9
- GunBir-O combines with Engine Gattai Engine-O, Engine Gattai SeiKuu-O, and Engine Gattai Kyouretsu-O to form Engine-O G12.
Behind the scenes
- This combination's name is either a pun on the Japanese word ganbaru (頑張る) which means to work hard or to do one's best, or the portmanteau of the two Engines' speech quirks, Gangangan and barubaru. The latter is referenced in GP 07: Partner Amigo, after they destroyed Bombe Banki.
- When Carrigator transforms into the GunBir-O, his upper jaw seems to become flexible. The reason for this is unknown.
