2. Luke Skywalker (Star Wars)
Luke Skywalker could definitely wield a Blue Lantern ring; he was the 'new hope' after all. His character represents the hero archetype; that is the young man who is called to adventure, going out to face the trials and ordeals associated with becoming a hero, and coming back after his victory with a boon for the community. In a time of hardship for the Jedi and the rebel alliance, Luke became their powerful new ally who could help to stop the Empire and destroy the planet-busting Deathstar, which would have brought destruction to every corner of the galaxy. To combine his Jedi/force powers and his lightsaber with a Blue Lantern ring would make him an extremely powerful warrior - one that the Empire or the Sith would be hard-pressed to combat.
