Miranda Lawson.

Miranda in Mass Effect 2 and 3 (from personal thoughts on the character), came along as quite the elitist type, tough, and the smart talker. Though I wasn't so sure on her at first, I grew to like her headstrong, superhuman ways along with her "asset's", she's one of ME's fem fatale's with a lot of charm.

Note I do not own this creation, it belongs to its creator and Bioware/EA.
