Bakuryuu Gattai KillerOh

"Burstosaur Fusion! KillerOh!"

KillerOh (キラー王 キラーオー): When Blastasaurs TopGaler and Stegoslidon combine, they form KillerOh. It has the Burstosaur Hissatsu Death Stinger and Burstosaur Hissatsu Death Combustion as its finishers. Other attacks are the Fillet Strike, Death Combustion Fire, and Big Blastasaur Advance Attack. KillerOh can adopt all of the arm power-ups from the other relevant Burstosaur.

Burstosaur Stegoslidon
See also: Stegozord "Stego!"

Burstosaur Stegoslidon (爆竜ステゴスライドン): A Stegosaurus nicknamed "Stego" (ステゴ), who could combine with AbarenOh to form AbarenOh Slidon, serving as a surfboard. He can similarly attach to BakurenOh, and assumes the same position on Killer AbarenOh, Killer BakurenOh, and OoAbarenOh. He and TopGaler combine into KillerOh, in which Stego forms the main body and head. He was taken by AbareKiller temporarily via mind control, but after awaking with his own willpower (separating KillerOh in the process), he left only to return to AbareKiller's side by his own will so he could fight at his full potential. Stego seemed to be the only one to really care about Mikoto's life, aside from Lije/Lijewel. His personality is almost similar to Ptera, but he can be a dunce like Dimenoko from time to time. In the finale, Stego asked Trinoid 12: Yatsudenwani why he was still on Earth.

Burstosaur TopGaler
See also: Dragozord "Top!"

Burstosaur TopGaler (爆竜トップゲイラー): A Tupuxuara nicknamed "Top" (トップ) who was sealed for destroying a major DinoEarth city. He was found and released by AbareKiller, whom he partnered with. He often employs his great speed in battle, which has been clocked at an astounding Mach 20. He calls Mikoto "human", as a sign of the no-affection relationship between both. His personality is a hardcore lone wolf like his master. He died along with AbareKiller near the finale, finally acknowledging him as a friend, but returned in Dekaranger vs. Abaranger and combined with AbarenOh to become KillerAbarenOh. Form's KillerOh's limbs and the Gale Spear, or the wings of AbarenOh Galer or BakurenOh Galer and with Blastasaur Stegosraidon, also assumes the same wing position for KillerAbarenOh, Killer BakurenOh, or OoAbarenOh. He ends his sentences with the word "Gera" (ゲラ).

Killer AbarenOh
"Great Blastasaur Fusion! KillerAbarenoh!"

Great Burstosaur Fusion Killer AbarenOh (キラーアバレンオー): Created when AbarenOh combines with Burstosaurs Top and Stego, initially to defeat BakurenOh, then appearing later in the series. It attacks by using Stego to slide down Bracho's tail, back, and neck, and then uses Burstosaur Multi-Combine, at attack which uses Kera, Tyranno, Bachycelo, Dimenoko, Ankylo, and Parasa as arms at an extremely fast rate before using the Flying Drill Spin finisher.

TopGaler can similarly combine with BakurenOh to form Killer Bakurenoh, though this is never seen in the footage. In Dekaranger vs. Abaranger, Killer AbarenOh is formed without Stegoslidon and its finisher in the teamup is Gatling Drill Spin attack by having the Dekaranger's Super Dekaranger Robo propel Killer Abarenoh forward with its Gatling Punch attack for its Flying Drill Spin instead of Stegoslidon.
