A remarkable individual from an unremarkable tribe in Utah, Vulpes was brought into the Caesar's Legion as a child. Having survived training, he was made a legionary and fought well enough to be promoted to the rank of Decanus. He became a Frumentarius following a brilliant tactical maneuver, when in a battle against a tribe, he broke ranks and led his squad through a hole in the enemy defenses, capturing the tribe's chieftain. While his centurion wanted him crucified for disobeying orders, Caesar saw potential in the young Decanus and found a more interesting use of him. According to Ulysses, Vulpes Inculta was responsible for the pacification of the Twisted Hairs at Dry Wells once the Legion's campaign ended in Arizona. Those of the Twisted Hairs who resisted were crucified along the sides of Interstate 40.
By 2281, Vulpes is the leader of the Frumentarii and the mastermind behind many of the Legion's intrigues, notably the slaughter at Nipton as well as the destruction of Camp Searchlight, which was destroyed after Legionaries released the contents of several radioactive waste containers kept in the city's fire station. This severely weakened the NCR's position in the area and allowed the Legion to cross the Colorado river and establish an outpost at Cottonwood Cove.
If Vulpes is killed by the Courier, a man named Alerio will give you Caesar's Mark instead of Vulpes. Alerio will mention the death of "the fearless Vulpes Inculta" as an example of a crime the Courier is being forgiven for.
If Vulpes is killed by the Courier, Caesar will mention you killing him as part of his greeting; he will sound impressed.
If the Courier passes Nipton and first encounters Vulpes in New Vegas, Vulpes will start the Nipton conversation with a mention of that encounter on The Strip, wondering if the Courier recognizes him, after which his normal Nipton dialogue commences; however, if Vulpes has died by the time the Courier approaches the Nipton Town Hall, Gabban will be coordinating the lottery in his place.
Vulpes Inculta is likely to be the first member of Caesar's Legion encountered by the Courier in the Mojave Wasteland. He's originally found at Nipton after obliterating the town with his Frumentarii henchmen. When speaking to the Courier, he'll explain the reason for destroying the settlement, as well as give an assignment to spread the word of Legion atrocities. If the player tells Vulpes that you appreciate the Legion's form of justice, the player will gain fame with the Legion. Choosing the second option: "I guess they got what was coming to them.", also gains Legion fame.
Killing Vulpes on The Strip when he comes to offer you the Mark of Caesar does not result in the Securitrons attacking you or anyone else on the Strip becoming hostile. The same is true for Alerio. However, if you kill either of them, you gain Legion infamy, and you fail the The Finger of Suspicion quest. If either character gets too far away from the Tops before you kill them the Securitrons will become hostile.
If you reverse-pickpocket an explosive into him after he gives you the Mark of Caesar, you CAN still continue on with the Render Unto Caesar quest.
You can use the Terrifying Presence perk on Vulpes when you first meet him in Nipton, this will cause him to attack.
When he is followed from Nipton he will vanish as soon as he is out of the player's sights, but his men will go to the Legion Raid Camp.
Killing Vulpes will cause his corpse to disappear rather mysteriously.
Vulpes has a special factional setting that causes most random Wasteland creatures including deathclaws and super mutants as well as raiders to ignore him instead of attacking him. He will still be attacked by robots and NCR forces, however. His entourage does not have this factional setting, and will be attacked as normal by any Wasteland inhabitants.
Killing Vulpes after you receive the Mark of Caesar may cause the legionaries at Cottonwood Cove and The Fort to turn hostile for a few in-game days.
Although Vulpes is depicted with wavy, white hair on the Collector's Edition playing card, he has a black buzz cut in-game.
He is one of only five named characters in the base game to have "Very Evil" Karma.
ps3pcxbox360 There's a glitch which can prevent you from being able to speak with Vulpes, even when he triggers the conversation. The camera will zoom in on him like it would usually do when initiating conversation, but will then quickly retract, bringing the player back into control. Reloading to a recent save doesn't seem to fix the issue. A possible fix is to reload to a save before confronting Benny, then walking out of the casino before talking to Yes Man, this has been observed to work in several cases. This may be caused by obtaining a large amount of legion infamy. [verified]
xbox360 If you meet Vulpes Inculta at The Strip before meeting him at Nipton and then meet him at the Fort and THEN travel to Nipton you will spot him there but if you try to talk to him the camera will zoom in and zoom out. It is unknown as to why this happens. [verified]
