|Season:||Bakuryuu Sentai Abaranger|
Burstosaur Stegoslidon (爆竜ステゴスライドン Bakuryū Sutegosuraidon?): A Stegosaurus nicknamed "Stego" (ステゴ Stego?), who could combine with Top Galer 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 Dime from time to time. In the finale, Stego asked Yatsudenwani why he was still on Earth.
