18. Commander Shepard
Since everyone makes their own Commander Shepard and chooses how to play them, we all wind up with our own version. Shepard's morality and sexuality were up to you, and both were essential expressions of the character. The maverick with the alien girlfriend or the by-the-book hero who doesn't date within the squad? Both were valid, like every other permutation. We identified with Shepard because we made Shepard our own.
Iconic moment: A reporter asks Shepard some sensitive questions. How to respond? You can give away information, deflect the question, end the interview, blame your superiors, or punch her in the face. All are fair options.
