Game: Resident Evil 2
Year: 1998-present

Ada Wong is supposed to be a secret agent, but we know any chick that walks around in a red dress and a choker is a straight trifey! Not that that's a problem; the skills needed to be a double agent are the same ones that help someone creep. And with a character based on La Femme Nikita, this trifey will be at enshrined in fanboy canon forever more.
