A tall man, standing at 6'5" (1.96 m), Aurelius was selected by Caesar to establish a bridgehead on the west bank of the Colorado River after Vulpes Inculta engineered the destruction of Camp Searchlight. Aurelius selected Cottonwood Cove as his base of operations, right across the Colorado's narrows. Although he was assigned only two contubernia (two squads of eight men each), his aggressive tactics and ruthless preying on NCR Army patrols allowed him to kill and capture four times as many enemy soldiers (around 64 casualties for the NCR, in other words). His second in command, Decanus Severus, is instrumental in Aurelius' efforts as quartermaster.
Aurelius has every reason to be proud of his standing as a centurion, but does not take kindly to people who eclipse him or test his patience (he has a habit of crucifying the latter). With his pride comes the show of his centurion armor which he earned through his prolific killing of profligate NCR troopers and his utter devotion to Caesar making him worthy to bear such armor. Adding to his aggressive demeanor is his abject hatred of profligates. He considers them cowards, particularly when they refuse to face his forces openly and try to fight through clever means. He takes an abject delight in the mere thought of killing NCR troopers. He even offers a bounty to any who turn in NCR dogtags to him, and it is possible to earn his respect for killings assumed with acquiring the dogtags. In fact, he might even admit that he misjudged someone if they prove to be a warrior on par with Legion veterans.
However, Aurelius does seem to have a softer side, with a toy car, teddy bear and a Grognak the Barbarian comic in his office. There is also beer and cigarettes there, and the question of whether it is his personal stash or confiscated contraband remains open.
Eye for an Eye: If siding with the NCR, Aurelius and the rest of Cottonwood Cove's legionaries must be killed to complete the final part of the quest. If siding with the Legion, he may be questioned for bad intel during the quest for Legion Fame and 500XP.
Even if the player character has an "Idolized" reputation with Caesar's Legion, Aurelius of Phoenix will still greet the player character with "Get moving, Profligate!"; however, giving him large amounts of NCR dogtags will still yield compliments from him.

↑Aurelius is one of the few characters with such a custom height.
↑The Courier: "You must be the one in charge here." Aurelius of Phoenix: "Of course I am, you fool. I am a Centurion! When Vulpes Inculta drove the NCR from Searchlight by clever means, Caesar himself ordered me to set up this camp and harass the Profligates! It's a modest presence, a single finger of the Legion reaching across the river's narrows. But with me here, it has an iron knuckle." (Aurelius of Phoenix's dialogue)
↑The Courier: "Does the Legion see much action here?" Aurelius of Phoenix: "As much as the Profligates' cowardice will allow. They haven't found the balls to attack us here, but we catch them out on patrols. With two contubernia at my command, I've killed and captured four times my numbers." (Aurelius of Phoenix's dialogue)
↑The Courier: "If you trade me ammo and supplies instead, I can stay in the area, racking up kills." Aurelius of Phoenix: "[SUCCEEDED] Go see Decanus Severus when you have tags, in that case. He watches over our stores." (Aurelius of Phoenix's dialogue)
↑Aurelius of Phoenix: "A Profligate bearing the Mark of Caesar? What is the world coming to? Cursor Lucullus is waiting for you with the barge at the docks. He will take you to The Fort to speak with Caesar." (Aurelius of Phoenix's dialogue)
↑The Courier: "That's some armor you're wearing." Aurelius of Phoenix: "It is the armor of a Centurion. You have the rare honor of beholding it unspattered by the blood of my inferiors." (Aurelius of Phoenix's dialogue)
↑The Courier: "How many dog tags to get your helmet?" Aurelius of Phoenix: "[FAILED] Nothing on this Earth could make you worthy to wear the armor of a Centurion. Do not ask again." (Aurelius of Phoenix's dialogue)
↑The Courier: "An NCR officer asked me to plant this listening device here. (Give Aurelius the NCR bug)" Aurelius of Phoenix: "The things the Profligates will build, to spy on us like cowards with little machines! Find that officer and give him this old map of our patrol routes. The Profligates will try to set up ambushes... and we'll be waiting for them." (Aurelius of Phoenix's dialogue)
↑Aurelius of Phoenix: "You taught Severus well! Soon I'll wear a necklace of Profligates' toes, blown off by their own mines!" (Aurelius of Phoenix's dialogue)
↑The Courier: "Will you pay a bounty for NCR troops I kill?" Aurelius of Phoenix: "The killing of Profligates should never go unrewarded. I'll pay you a small sum per tag." (Aurelius of Phoenix's dialogue)
↑The Courier: "I have dog tags to turn in." Aurelius of Phoenix: "Good, good! Your growing number of NCR kills rivals most legionaries. Keep up the good work!" (Aurelius of Phoenix's dialogue)
↑The Courier: "I have dog tags to turn in." Aurelius of Phoenix: "Ha! Perhaps I was wrong about your skills, Profligate. Your kill count rivals some of our best warriors!" (Aurelius of Phoenix's dialogue)
