- "Bakuryuu Combine! AbarenOh!"
- ―Combination announcement[src]
AbarenOh (アバレンオー Abaren'ō, Riot Union King): The primary mecha of the Abarangers, formed from the combination of Tyranno, Kera, and Ptera. AbarenOh is armed with Tyranno's Tyranno Drill (ティラノドリル Tirano Doriru) on its left arm which it uses in its Bakuryuu Blitz Drill Spin (爆竜電撃ドリルスピン Bakuryū Dengeki Doriru Supin) finisher to drill through its opponent. Alternatively, the Tyranno Drill and Kera's head can be detached-revealing a pair of human hands-and formed into a lance and shield, the former of which Abarenoh can throw like a spear in its Bakuryuu Salmon Hunter (爆竜サーモンハンター Bakuryū Sāmon Hantā) attack. Other attacks/weapons include the Ptera Cutter (プテラカッター Putera Kattā) boomerang formed from Ptera's wings, the Bakuryuu Blast (爆竜ブラスト Bakuryū Burasuto) eye beams, theTricera Punch (トリケラパンチ Torikera Panchi) with the Tricera fist, and the Bakuryuu Fire (爆竜ファイヤー Bakuryū Faiyā) flame blast from Tyranno's mouth. Additionally, Abarenoh can switch out one or both of its arms with any of the supplementary Bakuryuu to form alternate combinations with different combat abilities. On one occasion AbarenOh powered itself up using the Dino Guts of the three main Abaranger to defeat KillerGhost II. On another occasion it combined it's energies with KillerOh and MaxOhJa for an energy attack called the Special Bakuryuu Great Charge Attack to destroy Trinoid 1: Dragondoran.
Tyranno's tail can turn into the Double-Tail Sword.

AbarenOhji (アバレンオージ Abaren'ōji, Riot Union Prince) is a combination without Ptera. This was created by Ryouga in episode 14 due to Ptera and Ranru's hesitation to destroy the Giganoid. This combination would not be used afterwards.

- In Abaranger vs Hurricaneger, upon gaining the powers of the Hurricanegers and the Gouraigers' courage (using the kanjis for "Destroy", "Reverse", "Sword", "Roaring" and "Thunder"), AbarenOh becomes Senpuu Gourai AbarenOh (旋風轟雷アバレンオー Senpū Gōrai Abaren'ō), armed with a golden version of the Sword Slasher.

When GokaiOh and Gosei Great faced the Black Cross Colossus, the mecha of the first 33 Super Sentai, including AbarenOh 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, AbarenOh fought alongside Galaxy Mega and Daizyujin to destroy Danger Cabinet-Director Chirakasonne. 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.
Through the Super Sentai Zyudenchi of the Abarangers, Gabutyra was able to summon Bakuryuu Tyrannosaurus alongside Guardian Beast Tyrannosaurus to aid him in fighting the Giant Zorima and enlarged Cambrima. When Space War God Borudosu landed on Earth, Kyoryuzin, Daizyujin and AbarenOh were formed.

- AbarenOh is the first dinosaur Sentai Robo that can be formed with only two Mechas.
