Debo Royaroya

Debo Royaroya is a Debo Monster themed after a prison. Debo Royaroya was created to serve Dogold in making humans angry. Able to use his Chain Roya to capture humans, Royaroya targets martial artists and athletes before targeting the Rippukan family. He later managed to capture Souji's father, with King following suit, but both were free from their containment thanks to a resolved Souji.

After being put down by a Electro-Beast Brave Slash from Kyoryu Green and a Gabutyra + Gabutyra Electro-Beast Brave Finish from Kyoryu Red, Debo Royaroya was revitalized and enlarged by Luckyuro, but was finally defeated with Kyoryuzin Stegotchi Zakutor's Brave Finish.
