Samara

"By the code I will serve you Shepard. Your choices are my choices. Your morals are my morals. Your wishes are my code."

Samara is an asari Justicar, a lawless vigilante that operates on a strict code outside of government rule. Her strong conviction to her position is said to stem from a past incident that has left her with a burden of guilt. She is a powerful biotic, distinguished by her graceful movements in combat. She is nearly 1000 years old.

Samara is voiced by Maggie Baird.

Asari Justicar is Samara's class power.

Dossier
In Mass Effect 2, Commander Shepard heads to Illium in search of Samara, believing that her skills as a Justicar and biotic will assist the Commander's mission to stop the Collectors' galaxy-wide abduction of humans.

Once on Illium, Shepard speaks to an asari police officer, who points them in the direction of a local mercenary hideout. Shepard's team head to the hideout and arrive to find Samara brutally interrogating a mercenary. The interrogation goes bad and Samara ends up killing the mercenary and is subsequently arrested by the asari police, but before being taken away Shepard manages to get a moment to talk to her. She tells Shepard's team to find more information on the mercenary group and to track down a ship owned by the mercenary's allies that had just escaped with Samara's target prior to their arrival.

Loyalty
Samara's loyalty quest concerns her daugher Morinth. Morinth is an Ardat-Yakshi, meaning she possesses a genetic mutation that causes her to kill her mates. Samara has sworn to kill her, and has learned that Morinth has just murdered again on Omega. After Samara and Shepard investigation the victims apartment on Omega, Shepard enters Afterlife in order to gain Morinth's attention and lure her away to her apartment, where Samara can kill her. At the apartment, Shepard has the option of siding with Morinth. If shepard does so, Samara is killed and Morinth joins the team. Otherwise, Samara kills Morinth, and unlocks her Reave ability.

Samara's Appearance
Samara's armor and jewelry were created with feminine lines and ornate detailing meant to capture her archetypal description of "mystic warrior".
