Bakuryuu Gattai AbarenOh

"Burstosaur Fusion! AbarenOh!"

AbarenOh (アバレンオー): When Tyranno, Kera, and Ptera combine, they form AbarenOh - a humanoid fighting machine. AbarenOh's finisher is the Burstosaur Blitzkrieg Drill Spin where it launches itself forward and drills through its opponent with the drill mounted on its left arm. Other attacks are the Ptera Cutter, Burstosaur Blast, Tricera Punch, Burstosaur Fire Burst, Tyranno Drill, and Burstosaur Salmon Hunter.

Tyranno's tail can turn into the Double-Tail Sword.

Burstosaurs
The Burstosaurs (爆竜) are giant beasts from Dino Earth that evolved from the dinosaurs, they had a mutual friendship with the Dino People (竜人) until the Evorians attacked. While most of the Burstosaur eggs were sent to Earth, Tyranno, Kera, and Ptera fell under the Evolien's control. Sent to Earth, the three went on a path of destruction until their partners freed them.

Burstosaur Tyrannosaurus
"Tyranno!"

Burstosaur Tyrannosaurus (爆竜ティラノサウルス): Nicknamed "Tyranno" (ティラノ), the strongest of the three Burstosaurs. His jaws, strength and sharp claws make him a tough opponent, but his tail is his greatest weapon, able to drill through anything. Although wise, he has a short fuse when it comes to Ryouga Hakua. He shows sympathy towards Mai Hakua since he understands the feelings of a father because he lost his wife and only child on Dino Earth to the Evolien, so he constantly pushes Ryouga up to be a good father figure for Mai. In fact, in the finale, Tyranno jokingly said to Ryouga that if he and Mai are not happy, he'd come back and get him. Forms the majority of AbarenOh: the head, legs, body, and left arm, and the blade of the Double-Tail Sword. Detaches and donates his tail to another robo combination to add "Drill" suffix to the name, or with the Blastasaur Carnoryutus's tail, the "Twin Drill'" suffix. He ends his sentences with the word "Tera".

Burstosaur Triceratops
"Kera!"

Burstosaur Triceratops (爆竜トリケラトプス): Nicknamed "Kera" (ケラ), the armored one of the three Burstosaurs, Kera can take a great deal of punishment from an opponent; he seems strong enough to topple every building in downtown Japan. Kera is actually the youngest of the three Burstosaurs, as his voice sounds like a Japanese pre-teen. In Episode 36, he wished to become human and suddenly became a little boy, the transformation later revealed to be caused by an angel much to God's dismay. He fell in love with a woman, but sacrificed his human life to turn back into his normal form in order to protect Yukito Sanjyou. In the finale, Kera thanked Yukito for everything. Forms AbarenOh's right arm and shield and the handle of the Double-Tail Sword. Becomes a swap-in arm of another robo combination to add the "Triceratops" suffix to the robo (this is never seen in the footage). He ends his sentences with the word "Kera".

Burstosaur Pteranodon
"Ptera!"

Burstosaur Pteranodon (爆竜プテラノドン): Nicknamed "Ptera" (プテラ), the fastest of the three Burstosaurs, she can reach speeds of Mach 1.2 and higher, with her wings, beak, and shockwaves effective on any enemy. A kind and sweet Burstosaur. In the finale, Ptera said to Ranru Itsuki to find a nice boyfriend. Forms AbarenOh's helmet and "gown", the last can be removed for the Ptera Cutter, a bladed boomerang used by AbarenOh. She ends her sentences with the word "Pura".

AbarenOhJi
AbarenOhji (アバレンオージ) is a combination without Ptera. This was created by Ryouga in episode 14 because Ptrera and Ranru were both hesitant to destroy the Giganoid, but it is not used again afterwards.

Gokaiger
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.
