Commanding Officer of the Normandy and the current Avatar. Born on Mindoir with her parents and younger sister Talitha, and was traumatized when batarian raiders attacked the planet for slaves, leaving her with a bad temper and a deep hatred for batarians and slavers of all types. Later resulted in the slaughter at Torfan, where she and her team managed to root out the batarians despite 97% casualties, and discovered Shepard was the Avatar. Later promoted to become the first human Spectre, and assigned to stop Saren.
- Big Sister Instinct: When she finds out Talitha was kidnapped by Phoenix, she nearly goes into the Avatar State.
- No "nearly" about it: when she finds the Phoenix ships carrying the kidnapped Grissom Academy students, her manifestation of the Avatar State is so powerful that her mandala literally consumes enough energy to becomes mass (as by the famous relativity equation).
- Broken Bird: Even more than Korra or Aang at their lowest points. She gets better over time, but still falls into this at times.
- Character Development: Related to the above, in game terms, Shepard goes from a bitter, angry, alcoholic Renegade-type to a selfless, heroic, and kind Paragon. It's one helluva long, painful, difficult, but utterly worthwhile journey.
- Dark and Troubled Past: Her parents and sister were killed by batarian slavers on Mindoir. Though her sister later turns out to have been taken as a slave, and is later freed.
- Drives Like Crazy: Her squad gets very concerned when she's behind the wheel.

- Dishing Out Dirt: Her earthbending.
- Extra Oredinary: She knows metalbending.
- Making a Splash: Waterbending, which she's good enough at to teach Tali.
- Blood Magic: Knows how to bloodbend.
- Mind over Matter: Biotics is a form of bending, according to Benezia. Also apparently her real birth element; she was noted as having great biotic potential, due to the Eezo present in her.
- Playing with Fire
- Shock and Awe: Can generate lightning incredibly fast, and redirect it as well.
- Fantastic Racism: Views batarians as scum.
- Good Is Not Nice/Good Is Not Soft: She becomes more and more Paragon over the story. She is still solidly Renegade when it comes to her enemies, however.
- Interspecies Romance: With Liara.
- Knight in Sour Armor: Believes that since the universe is not fair, she will have to make it fair.
- Single Woman Seeks Good Man: The main reason she starts to like Kaiden, and later falls in love with Liara.
- Survivor's Guilt: Feels guilty early on that she didn't die with her family on Mindoir. She gets better over time.
- Took a Level in Kindness: Becomes more and more of a Paragon over time.
- Would Hurt a Child: On Torfan, to the batarian children... who were hauling around explosives their parents gave them and trying to use them on the Alliance soldiers.
A Sentinel born in Republic City, who was among those sent to Jump Zero, where he was trained as a biotic.

Later adopted, she joined the Systems Alliance military shortly before Mindoir, and fought alongside Shepard there, being one of the few survivors besides her and Major Kiel. Joins the Normandy crew much earlier, and Shepard's oldest remaining friend.
- Adaptational Heroism: Starts out as a member of the Systems Alliance military, and one of Shepard's closest friends, instead of a feared convict.
- Dark and Troubled Past: The same as in canon, though she's suppressed most of the memories by the main story.
- Happily Adopted: While she was very angry/troubled as a child, it's clear her adoptive parents did their best to raise her. She's very grateful to them for this.
- Jerk with a Heart of Gold:
- Mind over Matter: A strong enough biotic to fight Benezia one on one.
- One-Woman Army: Destroys a Phoenixnote base by herself, and everyone in it.
- Only Friend: Was this to Shepard when the story started.
- Precision F-Strike: Just like in canon, she is prone to this.
Known in the main timeline as Ashley Williams, here descended from the Si Wong tribes and renamed. The former Gunnery Chief on Eden Prime before her promotion to the Normandy.

Joined Shepard afterwards as in canon, as the XO of the Normandy.
- Body Horror: Underwent it due to Host vs Eezo.
- Dark and Troubled Past: Henri Lawson was even worse than in canon; She's not the first Miranda Lawson that Henri kept. She was the first that survived what Henri did.
- Heroic BSoD: After she discovers Weaver is the Illusive Man, she goes into this until after Jack helps her snap out of it.
- Making a Splash: She's a waterbender, though she bemoans how "useless" it is at times... and often proceeds to use it in a bdass way afterwards.
- Blood Magic: She knows how to bloodbend.
- Pre-Mortem One-Liner: When she finds Wilson, she has not had the best day."Hello, Wilson."BANG!"Goodbye, Wilson."
A salarian scientist, as in the main games, who was responsible for altering the Genophage to the Krogan to slow down their breeding. A former member of the Special Tasks Group, who Shepard recruits in order to find a way to defend themselves against the Collectors, though she is disturbed by his previous workings on the Genophage.
- Badass Normal: His abilities are based off of his technology and his time in the STG.
A Token Heroic Batarian, who initially, unlike in canon where he was a terrorist, uses the attack on an asteroid as a way to help a large number of batarian slaves escape the Hegemony's clutches. Later joins Garrus's team on Omega to help fight crime there, and the only other surviving member of said group.note Joins Shepard out of loyalty to Garrus; cares little initially about saving humanity.

- Badass Normal: Has no bending, shamanistic abilities, or biotics whatsoever. He is no less awesome for the lack thereof.
- Headbutting Heroes: With Shepard, at first. Both grow out of it eventually.
- Sadistic Choice: During The Arrival, he's with Shepard and Rai Li at The Project. He is horrified by the idea of killing more than 300,000 of his people to destroy the Alpha Relay, but agrees to do it when Shepard points out that if they don't destroy it, the Reapers will invade and get their hands on the batarians.
- Shadow Archetype: To Shepard herself. He even notices this, and Shepard can't really argue with it after thinking about it, since she would have done what he did if she was in his situation.
- The Stoic: He almost never loses his cool.
- Stronger with Age: He's a downplayed version of this trope, because while he is apparently at least the batarian equivalent of 50, he is in extremely good condition for his age.
An asari Justicar as in canon, and an incredibly powerful and skilled biotic, who seeks to bring down her daughter Morinth, an Ardat-Yakshi who is responsible for hundreds, possibly thousands, of deaths. Joins Shepard in order to teach her how to use her biotics after she is brought back to life.

- Fights Like a Normal: He usually just sticks with guns, speed, and his martial arts, despite having both bending and biotics.
- Heroic Sacrifice: Holds off the Collectors to give the rest of the team enough time to escape.
- Making a Splash: He's a waterbender, though he admits he's not the best at it. He mostly uses it to pull out the fluid in his lungs from Kepral's Syndrome (though it just comes back faster as a result).

- Odd Friendship: With Samara, and it becomes full-born Ship Tease later on.
- Your Days Are Numbered: Due to Kepral's Syndrome.

A Prothean engineer, who Shepard rescues from the Collectors and Leviathan, cutting out a large part of their ability to reinforce themselves. Joins her crew for a short time, later leaves.

- Cloning Blues: There were at least 107 other clones of Shepard made who were implanted with the Paragon Device who didn't gain the full usage of their abilities. Zia has nightmares about it.
- Elemental Powers: Thanks to the Paragon Device granting her all the elements as well as biotics, a chance of roughly 1 in 17 billion.
- HeelFace Turn: Shoots Brooks in the legs and frees Shepard and her team after she traps them and confirms Cat-6 is done for.
- What You Are in the Dark: EDI notes that she could have just left Brooks behind and not tried to stop her, but instead did her best to ensure the scheme never succeeded.
- Your Days Are Numbered: Her max life expectancy, due to being a flash-grown clone, is to be 15 years old. And that's with everything going her way, genetic enhancements, eating healthy, etc. And after Thessia, her number seems to be coming up a lot sooner than expected...
- Heroic RRoD: What her life has boiled down to. The strain of fighting on the front lines of the Reaper war alongside Shepard vastly reduced her lifespan and sent her body into a death spiral of organ failure. She's more or less surviving on borrowed time and generous transplants from Shepard.
A surviving Prothean and their last Avatar. Noticeably more trained and knowledgeable about the Avatar and the Avatar State than Shepard is. Unearthed from a diamond he sealed himself (and his daughter) in on Eden Prime shortly after the Reaper invasion began.
- Elemental Powers: As befits an Avatar.
- Interspecies Romance: He was apparently married to a ditakur, and even had a daughter with her (and yes, how impossible this should be is lampshaded continuously.)

- Nice Guy: Easily one of the most polite members of Shepard's team.
- Noodle Incident: His past has apparently been a very strange one.
- For reference, he's been, among other things; a mercenary, an electrician, a thief, a forklift worker on Mindoir, a divorcee, and a cult member who left when they started worshiping him...
- Reincarnation: Ultimately revealed to be a soul reincarnating alongside the Avatar throughout the ages. Most pertinently, he (or his soul, rather) has been Kyoshi's husband, Roku's wife, Sokka, and Asami Sato. He's been unconsciously trailing behind Shepard for years, waiting to reunite with her.
