Ohranger Robo (オーレンジャーロボ Ōrenjā Robo): The primary mecha of the Ohrangers. OhrangerRobo is able to equip itself with one of five interchangeable "Helmets" supplied from its individual components which allow it to switch between different powers and attacks to suit changing battle conditions:
- Wing Head (ウィングヘッド Wingu Heddo): the default helmet which summons the Super Crown Sword (スーパークラウンソード Sūpā Kuraun Sōdo) for its Crown Final Crash (クラウンファイナルクラッシュ Kuraun Fainaru Kurasshu), Chouriki Crown Sword Shoot, and Chouriki Crown Spark Shield attacks.
- Horn Head (ホーンヘッド Hōn Heddo): fires the Chouriki Taurus Thunder (超力タウラスサンダー Chōriki Taurasu Sandā) lightning blast from its horns and performs the Taurus Dive headbutt.
- Graviton Head (グラビトンヘッド Gurabiton Heddo): enables it to perform the Leon Punch (レオンパンチ Reon Panchi) and fires the telekinetic Chouriki Leon Beam (超力レオンビーム Chōriki Reon Bīmu) from its forehead.
- Vulcan Head (バルカンヘッド Barukan Heddo): armed with the dual Chouriki Dogu Vulcan (超力ドグバルカン Chōriki Dogu Barukan) guns and allows it to perform the Chouriki Jump Crash and the Dogu Sky Kick (ドグスカイキック Dogu Sukai Kikku).
- Cannon Head (キャノンヘッド Kyanon Heddo): armed with the Chouriki Moa Cannon (超力モアキャノン Chōriki Moa Kyanon) and allows it to perform the Moa Tornado spin attack.
The toy version was equipped with posts on the back of its legs and body that allowed it to store any unused helmets on its body. Ohranger Robo was damaged badly in episode 19 by Bara Builder but was fully repaired by episode 22. Ohranger Robo's power later helped to power up GaoKing in Gaoranger vs Super Sentai.
Chouriki Mobiles (超力モビル Chōriki Mobiru, Super Power Mobiles): Five mecha built by Miura to aid the Ohrangers in fighting the armies of Baranoia. In addition to forming Ohranger Robo with the command "Super-Powered Combination" (超力合体 Chōriki Gattai), each of the Chouriki Mobiles provide one of the five helmets used by Ohranger Robo.

Carranger vs. Ohranger
The Carrangers briefly operated the Ohranger Robo to rescue Goro Hoshino (OhRed) from Bowzock.
Gaoranger vs. Super Sentai
Years later, Sky Phoenix appeared as part of an army of robots, animals, jets, machines and vehicles belonging to the first 25 red heroes. As anticipated by Sokichi Banba (Big One), they were led by Akira Shinmei (AoRenger) and Chief Counsellor Naoyuki Miura to help fight Lost Highness Rakushaasa.
When GokaiOh and Gosei Great faced the Black Cross Colossus, the mecha of the first 33 Super Sentai, including Ohranger 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, Ohranger Robo fought alongside GaoKing and ChangeRobo to destroy Buredoran of the Chupacabra. 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 Ohranger, Buster Ohranger Robo 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.
