As an infant, Maya was identified as a Siren and given to the Order of the Impending Storm, the ruling order of monks on her homeworld of Athenas. She trained her Siren powers in secret until she reached adulthood, when the monks revealed her to the public as their goddess and savior. Irritated by the Order's short leash, she longed for adventure and expressed interest in traveling to Pandora to learn more about her Siren lineage. She eventually realized that the Order was using her as a threat to extort money and obedience from the people of Athenas. After Phaselocking and executing her handler Brother Sophis, she headed to Pandora to finally satisfy her curiosity about Sirens.
Maya already knew of the Vault and the presence of Eridium before arriving on Pandora. After Handsome Jack learned of Maya through Hyperion surveillance footage of Athenas, it presumably didn't take much effort to get the Siren on the train at the beginning of the game.
Action Skill: Phaselock. Base Cooldown is 13 seconds, base Duration is 5 seconds.
Maya's skill gives her the ability to suspend foes in another dimension. This can lock an opponent in a stasis, and can be upgraded to provide various damaging effects. This skill is useful for crowd control in both co-op and single player mode. Repeatedly Phaselocking the same enemy results in diminishing returns.
Maya has three Skill trees:

When Killing a Badass
- One less badass.
- Let's do that again sometime.
- That calmed him down some.
With Handsome Jack's voice
- This is interesting technology. I wonder how it -- oh God, I sound atrocious.
- The monks always said to know your enemy like you know yourself, but this voice is officially the creepiest god-damn thing ever. (while idle)
- I've never considered myself an angry person, but if I have to speak with this fascist voice much longer, I will rip out my own voice box and stomp on it. (while idle)
- The silence is (almost threw-up)... oh god, hearing Jack's voice come out of me just made me throw-up in my mouth a little. (while idle)
- Siren here, testing tes...ting -- oh dear, I wanna punch myself in the throat.
Spotting a badass
- Careful! Badass!
- Stay focused, Badass!
- Look out, Badass!
- I'll never forget what the Head Monk told me right before I left the Abbey: "Child, you have so much left to learn" he said. I imagine he would have continued speaking, had I not pulled the trigger.
- This silence reminds me of the Abbey... I hated the god damn Abbey.
- Twenty-seven years of training just so I could stare at nothing.
- The monks told me to respect silence, to treasure the moments of inaction so that combat could be even more invigorating. Now I truly understand: they didn't know what the HELL they were talking about!
- The impossible has happened. I... am... bored.
- (sighs) Oh my God, this is dull.
- Through meditation, I see everything: eternity, the whole of existence... aaand right now, it is boring the hell out of me.
- I'm all for meditation, but this is ridiculous.
- I came to this planet to fight, not to wait.
Recovery [Kill Revive]
- I'm back, bitches!
- Who's next?

- If you say so...
Losing a Duel
- You fought well.
- I can see to your skill.
- Well played... bitch.

- Perhaps next time

- Well done.
Winning a duel
- Thanks for the spar.
- Don't let it get you down.
- How pleasing
- You fought bravely.
- I am victorious!
- Hm. This area kinda smells like butts and dead people. (entering Unassuming Docks)
- Good morrow, fair maiden. Does something trouble you? (talking to Ellie/Eleanor in Flamerock Refuge)
- Lots and lots of books... and guns. (on what she's going to spend prize money on)
Dropping the Crit
- Son of a...
- WHY is this gun so slippery?
- I know almost nothing about romance, so please pretend I just said something really inspiring about the power of love. (words of encouragement for Ed)
- (when tasting whiskey):
- That... was not for me.
- Bit better, but -- hic -- not great.
- That felt good.
- Everyone will tell you small lies, except the people you love, who will tell you large ones. (to make the baby cry)
- There was once an older man. He's dead now, of course. (when Moxxi asks about a mister-or-missus Vault Hunter in Maya's life)
- Romaburn plants don't grow out here -- I'm marginally sure this is just rolled-up human flesh dipped in gasoline. (when collecting the cigar box)
- Pah! No. (when Innuendobot asks if his Oedipal feelings for Moxxi are normal)
- (when collecting Stella's wig):
- Hey, Junkbot. Stella. Could I borrow that wig?
- Ummm... I still need it for this quest, though.
- I'M A COMPLETIONIST. SORRY!
- I really hope he's just using this for maintenance. (when collecting the can of grease)
- It's succeeded in irritating me, if nothing else. (when Innuendobot asks if his negging made Maya love him)
- And that's why you never take orders. If I'm gonna get blown up, I wanna get blown up for my own reasons. (When finding Axton's assassin)
- The impact pattern's not that big. Fall must not have been high enough for him to lose consciousness before hitting the ground. Ugh. (When finding Gaige's assassin)
- Consider yourself lucky. That poison must have worked quickly. I wouldn't have. (When finding Maya's assassin)
- Someone once said, he who sets out on revenge should first dig two graves. That's a stupid-ass quote, revenge is awesome. (When finding Salvador's assassin)
- Poor attempt at faking a suicide, but clearly a doctor's hands at work. (When finding Krieg's assassin)
- What am I, uh... what am I looking at? (When finding Zer0's assassin)
- Maya's equipped class mod is represented by a book attached to her left hip.
- Maya is wanted for the crime of being a siren, the bounty on her head is $720,000,000,000.
- An ECHO recording appears in Maya's inventory at the start of the game about her training with a group of mysterious "Brothers" and explains why she left her planet to come to Pandora.
- Maya's back story ECHO recordings are located in the Wildlife Exploitation Preserve. The recordings override earlier promotional material regarding her age, giving her at least 27 years instead of 25.
- One of Maya's body skins, "Slice of Fried Gold" is a reference to the movie Shaun of the Dead. 
- Maya's, "So it goes..." quote comes from Kurt Vonnegut's novel Slaughterhouse-Five in which the phrase is used as a refrain after the death of any character.
- Maya was the first Vault Hunter to meet Krieg. She originally mistook him for a common bandit. Krieg's inner voice then persuaded Krieg to save Maya's life from an approaching Rat horde. 
- According to Mad Moxxi, Maya gives her a "ladyboner".
- For unknown reasons, both Maya and Lilith, another Siren, are frequently referred to as "the most powerful Siren on Pandora", respectively. Whom truly is more powerful is unknown.
- It was confirmed by Borderlands 2 Lead Writer Anthony Burch on twitter that Maya is asexual.
