3. Kyle Katarn
Quite possibly the most dangerous man in the galaxy, Katarn possesses a multitude of skills honed over years of experience. A former Imperial stormtrooper who defected to the Rebellion, Katarn became a one man demolition crew for the alliance, pulling off invaluable missions such as destroying the Imperials Dark Trooper project. Later, Katarn trained himself to be a Jedi ( I imagine that's fairly difficult), holding his own with some of Emperor Palpatine's trained Dark Jedi. Later, Katarn enrolled in Luke Skywalker's Jedi Academy, becoming one of the New Jedi Order's most respected Jedi Masters and proving invaluable in a number of conflicts. Katarn could easily be main character in his own spinoff movie or be major supporting character in the sequel trilogy, although he likely won't appear in either.
Who Should Play them: Ryan Gosling
