3. Tali
What is there to say about Tali that hasn't already been said as we 'aww!'d quietly to ourselves so much that we didn't stop looking like real men. The plight of her people? Heartbreaking. Her personal tale of woe with her father? Heartbreaking. Her fleet's threatening to kick her out under accusation of treason? I might as well not have had a heart after that if Bioware was just going to take it and twist it over and over again like that and NO THOSE AREN'T TEARS LEAVE ME ALONE! Tali'zorah vas Normandy is the heart of Shepard's crew, and the face of the Quarians in this harsh world. Well, masked face that turns out to hide a photoshopped picture. Still hot, though.
