Buzarai (ブザライ, Buzarai) and Kars (カーズ, Kāzu) are members of the Faudo cult. Generally acting as the brawn to Keith's brains, Buzarai is a silent, armor-like Mamodo whose powers center on the axe he wears on his back.
They first appeared along with Keith to attack Apollo's plane. He attack with Gazuron after Zatch`s group jumped out of the plane.
After that they, together with Keith, attacked Zatch and Kanchomé and Parco Folgore. They obey the orders of Keith. First they protect Keith with Go Gazushield, after Keith attacked Kanchomé but Kanchomé used Dika Poruk for help. Buzarai used Urujim Gazun. When Keith was distracted Zatch used Zakeruga. But Buzarai used Gazushield. Keith attacks Kanchomé. after Kanchomé hides but Kars discovered them and used Raja Gazun to discover where Kanchomé was.
Kanchomé escaped from the battle with Folgore. After Kanchomé come back alone to fight, suddenly Folgore appeared and used Dima Buruk to attack Keith. On Keith's order to stop the Kanchomé's clones, Buzarai used Gigano Gazuron but the Kanchomé clones stoped the spell with Zatch. Buzarai and Kars then used Go Gazuruk to attack the clones. After that he used his most powerful attack Dioga Gazuron to put an end to the battle but Kanchomé made a shield of clones however it only weakened his attack and Zatch used various Zagurzem's to power up Bao Zakeruga. The powered Bao Zakeruga was able to destroy this spell and burn Buzarai's book.
