Full list of appearances
Sun Vulcan Robo (サンバルカンロボ, San Barukan Robo) - The first combining Sentai robot. Cosmo Vulcan and Bull Vulcan combine when the command "Fusion! Grand Cross!" (合体グランドクロス, Gattai Gurando Kurosu) is given. It is armed with the Solar Sword (太陽剣, Taiyō Ken) and its finishing attack to destroy monsters is the Aurora Plasma Return (オーロラプラズマ返し, Ōrora Purazuma Kaeshi). Its other weapons are the Vul Shield (バルシールド, Baru Shīrudo), Vul Tonfa (バルトンファ, Baru Tonfa), Vul Hand (バルハンド, Baru Hando), Vulcan Sun, and Vulcan Cannons (バルカン砲, Barukan Jū).
Cosmo Vulcan (コスモバルカン, Kosumo Barukan) - It is piloted by VulEagle. It is stored in the Jaguar Vulcan's mouth. It forms Sun Vulcan Robo's head, arms, and body.
Bull Vulcan (ブルバルカン, Buru Barukan) - It is piloted by VulShark and VulPanther. It is stored in rear of the Jaguar Vulcan, divided in half. It forms the Sun Vulcan Robo's legs.
When GokaiOh and Gosei Great faced the Black Cross Colossus, the mecha of the first 33 Super Sentai, including Sun Vulcan Robo 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, Sun Vulcan Robo fought alongside Victory Robo and Goggle Robo to destroy Cleaning Minister Kireizky. 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.
Behind the scenes
- With this the first combining mecha, Cosmo Vulcan is the first mecha component with one individual pilot (Bull Vulcan had a combined control similar to many of the non-Red mecha pre-Great Five)
