7. Nathan Hale
The protagonist of both Resistance 1 and Resistance 2, Nathan Hale is the hero of the resistance against the conflict with the Chimerans, who threaten to take over the planet and drive the human race into extinction with their virus.
This badass may not have had the leading role in Resistance 3, which was given to Joseph Capelli, a family man, but he'd certainly be a better fit in Title Fight because of his presence in the first two games.
