Odiferus is incredibly arrogant and loves to talk about himself. He chats on and on about his many past accomplishments and loves to show off. He appears to be very true to his king, Ceaser, but in reality, he only likes punishing those when he is given the permission. He is a friendly person, if one can get past his narcissistic personality, but he is also sadistic and vain. He loves to be complimented in any way, shape, or form. He appears to have a bit of a flatulence problem, and either doesn't notice it, or doesn't care about its affect on others.
Odiferus Maximus is a fairly tall, well built, muscular, broad-shouldered man with the appearance of a man of relatively healthy middle-age. He has short dark hair and sideburns, and a 5 o' clock shadow. He wears golden armor, white underwear-length tights, and a short red cape. He has been described as "very handsome" by several over the course of the series.
He is first shown bragging to Ceaser about how he would never behave as such a coward as the clown facing a bull in the arena. He reveals that he is the champion cheriateer, before laying a heavy fart on Ceaser, who doesn't appreciate dealing with Odiferus's gas for nearly a millennium. When Ceaser shows interest in talking with Rudy Tabootie, Odiferus seems unimpressed and dislikes Ceaser paying more attention to a child than him. By Ceaser's orders, he invites Rudy and Snap up to Ceaser's throne, where Rudy speaks with Ceaser. When Snap seems to act out of order, Odiferus overreacts and chokes him until Ceaser orders him to release him. Moments later, Odiferus is outraged to hear that Ceaser plans for Rudy to sit at his right hand for the day, believing that only he deserves such a wright. Ceaser decides the title shall be held in a race.
During the race, Odiferus cheats constantly, ruining the duo's wheels, setting off bombs for them, but Rudy's chalk continuously saves them. Eventually, when the two nearly crash, Odiferus's horses jump out of the way and end up behind him. When Odiferus seems to be winning, He laughs victoriously, proudly farting loudly in the horses faces. The smell is so strong that it causes the horses to crash. Rudy catches up and wins, but doesn't accept the position, so it may be assumed that Odiferus regained his position at Ceaser's right hand.
