Originally from Hieronymous, Axton spent ten years with the Dahl military force, reaching the rank of sergeant. After his pursuit of personal glory and disregard for orders led to numerous compromised missions, his wife and commanding officer Sarah simultaneously divorced him and discharged him from the military. Sarah made it a point to highlight that this would lead to his death by firing squad, then ordered him not to flee to any of the numerous border worlds beyond Dahl's reach. Taking her not-so-subtle suggestion, Axton went AWOL, using his skills and turret as a mercenary on other planets.
Axton became aware of the Vault thanks to a radio advertisement orchestrated by Handsome Jack, who had been monitoring the Commando's most recent bounty hunt. Although Axton was turning in more bounties and making far more money than anyone else in Sheriff Youngblood's jurisdiction, he found that it was too easy, and the lure of fame, fortune, and challenging combat drew him to Pandora.
Axton is able to deploy a versatile Dahl Sabre Turret, a mounted gun featuring 360° rotation that can be upgraded with many weapons and abilities. The turret's duration is 20 seconds and its cooldown is 42 seconds.

- Hnggg. That sucks. I hate whiskey.
- I can't feel my face. Prob'ly a good thing.
- Sometimes you'll try to make people laugh by using a meme from the ECHOnet, but instead they'll track you down and set fire to your house. Look forward to that. (to make the baby cry)
- Dated a buncha people, but only got married the one time. Wonder how she's doin'. (when Moxxi asks about a mister-or-missus Vault Hunter in Axton's life)
- Times like this, a guy misses the high-quality stogies from the central planets. (when collecting the cigar box)
- Nah. That's weird as hell. (when Innuendobot asks if his Oedipal feelings for Moxxi are normal)
- (when collecting Stella's wig):
- Stella. Need your wig -- mind if I borrow it?

- Sorry, but I hate leaving quests unfinished!
- Ew. (when collecting the can of grease)
- I mean, a little. (when Innuendobot asks if his negging made Axton love him)

On the PlayStation vita version, there is a glitch where Axton's voice will be replaced with Salvador's voice. It's cause is unknown, but it was first noticed when his jump effort pants sounded different.
- Axton's melee weapon is a tomahawk.
- With careful point spending it is possible to get the turret featured in the opening title sequence. (Double Up and Mag Lock)
- Axton's ex-wife Sarah was also his former commanding officer, and Axton wears her dog tag and wedding band.
- Axton is wanted for war crimes, and the bounty on his head is $5,000,000,000, which is the lowest among the six playable Vault Hunters in Borderlands 2.
- Axton has a dislike of cats.
- Although Axtons sexuality has had controversy, Axton is officially bisexual.
- Axton was to be executed by a firing squad, avoiding the execution only because he went AWOL and went to Pandora.
- If Axton is the chosen as the starting character, an ECHO log will be in the inventory about Axton and his wife, Sarah. It plays the dialogue between them of Sarah discharging Axton from the military and suggesting that he go AWOL to the border worlds. She also gave him back her wedding ring, saying she never liked diamonds.
- When Axton deploys his Sabre Turret he sometimes addresses it with pet names such as "sweetie", "honey", "the Mrs.", or his "girlfriend".
- Axton's quote "throwing a masher" is a reference to the nickname of the German Model 24 grenade "the potato masher".
- Axton's quote "oscar-mike" is a phonetic alphabet delivery of the letter "O" and "M". This a military acronym used most often by infantrymen meaning 'on the move'.
