Series: Half-Life 2

Video game characters have rarely felt as intuitive, brilliantly true-to-life and emotionally three-dimensional as Alyx Vance, Gordon Freeman's crack shot second-in-command from Half-Life 2.

Alyx is adept at hacking, fighting and shooting—plus she already has a big enough back story to justify a large role—so she could realistically carry a whole series, if not a single game. Imagine what could be revealed about this key player in the Resistance if you learned about her from her own perspective. Her sizable charisma justifies a sizable reward.
