Phibrizzo is the main villain in Slayers Next
Hellmaster Phibrizzo was created by Ruby Eye Shabranigdo to be one of his Dark Lords for the war against Ceifeed. After war with Ceifeed, Shabranigdo have been divided in seven fragments. Phibrizzo and the others Dark Lords begin to look for the seven fragments of Shabranigdo. After 4000 years later Phibrizzo have found one of the fragment of Shabranigdo in a human named Lei Magnus. He then staged a worldwide war between several human nations and used the horrors to cause despair, sadness and other negative feelings to Lei Magnus thus awaking the fragment of Shabranigdo which took over his body and mind, and became the "Demon King of the North." Lei Magnus/Shabranigdo took command of the Mazoku armies and started a worldwide war against the Dragon Lords, servants of Ceifeed, and their troops.
Phibrizzo is cruel, ruthless, remorseless, vicious and deeply sadistic. He revels in his victims’ suffering and despair, as he did when he kills all of Lina Inverse’s friends one by one. To him, killing or tormenting someone, even a fellow Mazoku, is a game which he enjoys to no end. Like many Dark Lords, he acts with courtesy and polite manners, albeit generally sarcastic ones. Yet, he can recognize the potential of his enemies and he admits his surprise whenever someone exceeds his expectations. He is overproud and very confident in his own power, often to the point of arrogance. He never brags however, and every statement he makes about his strength is proven true shortly after.
His personality somehow fits his child-like appearance, given that he likes to entertain himself when he is bored. He teases his victims and he displays child-like dark humor. In a general way, he regards all lifeforms as mere toys which he uses in any way he wants and he is almost always acting playfully. He is very patient, being able to wait several centuries for an opportunity to strike and rarely making a move before having elaborated a plan, but at the same time he shows little patience when things don't go his way. His will to destroy the world is much greater than that of any other Mazoku. To him, this is not a goal but a dream and even a reason to exist, and he is exhilarated by its apparent success.
Phibrizzo is an extremely intelligent and cunning mastermind, as well as a master of deceit. He always achieves his goals through complicated schemes. He understands things quickly and he can easily adopt a backup plan when he needs to. He has a great understanding of human nature that enables him to adapt to almost anyone. He also proves to be a very convincing actor when he pretends to be an innocent orphan.
