Mass Effect: Ranking Every Main Squad Member In The Original Trilogy
8. Miranda Lawson
Voiced by the incredible Yvonne Strahovski, Miranda was a high ranking Cerberus operative whose loyalties were always in question. She had a mercurial nature that made the player always second guess every decision she made.
After a streak of mundane human characters, Miranda managed to bring genuine intrigue to the Normandy and growing close to her could be difficult as it felt like she could easily be playing Shepard at every turn.
Her traumatic past concerning her father and sister gave her some shading that allowed her to become a far more sympathetic character and one that was less guarded. Whereas other loyalty missions (well done or otherwise) could feel like the motions of the game at times, Miranda's felt like an honest progression of her relationship with Shepard that allowed her to open up to him and ask for his help.
Even though other Mass Effect 2 companions will place higher than her, Miranda felt like the quintessential companion of that game and her use towards the end of Mass Effect 3 reinforces that.
