Arbiter is a Pyrus Knight Percival and is used by Clint Kalik.
A no-nonsense Bakugan, Arbiter gets the job done before anything else. In close range, Arbiter can lure the opponent closer, only to have them blasted by streams of fire from the two dragon heads mounted on his shoulders.
Gruff, Arbiter is a far cry from cruel. Although he may not look it, Arbiter has always been caring. Nonetheless, he shows little mercy in battle.
Partnered with Clint for two years now, Arbiter has grown rather fond of his Brawler. He has been able to trust Clint's judgement, despite some of his partner's limitations.
Although never serious, Arbiter has found the young Helix Dragonoid to be a valuable ally. Despite this, he still hasn't come to tolerate Loki's pranks.
