Samara

Samara, the ancient Asari Justicar from Mass Effect 2, can make a return in Mass Effect 3, though her role is more limited and tied to specific narrative events. Her appearance is contingent on her survival in the previous game and certain story developments. If she is alive, she may offer her formidable combat skills and unwavering sense of justice.

Samara's presence in Mass Effect 3 is primarily linked to the Ardat-Yakshi storyline, specifically the mission Kallini: Ardat-Yakshi Monastery. If Samara survived Mass Effect 2 and you choose to pursue this mission, she will appear to aid Shepard. Her involvement is driven by her duty as a Justicar and her complex relationship with her daughters, Morinth and Rila.

To encounter Samara, you must have ensured her survival in Mass Effect 2. This typically involves making specific choices during her loyalty mission and ensuring she doesn't fall prey to her daughters' influence. If she is alive, the mission Kallini: Ardat-Yakshi Monastery will become available, and she will join Shepard for this critical undertaking.

Here's how to see Samara in Mass Effect 3:

Survival from Mass Effect 2: Samara must be alive at the end of Mass Effect 2.
Kallini: Ardat-Yakshi Monastery Mission: This specific mission is where she appears.
Justicar's Resolve: Her appearance is driven by her Justicar code and familial obligations.

Samara's stoic demeanor and powerful biotic abilities make her a formidable ally, even in a limited capacity. Her presence adds a significant emotional and narrative weight to the Ardat-Yakshi storyline.
