Carlisle Cullen: Peter Facinelli's vamp is the head of the Cullen clan, but he's no ordinary bloodsucker. His resistance to human blood and his ability to feel compassion allows Esme's husband and Edward, Rosalie, Jasper & Alice's adoptive dad to function as a doctor, healing others.
Albus Dumbledore: Michael Gambon's magic man sorta deserves his own What Would Dumbledore Do? novelty franchise. The Hogwarts headmaster has saved Harry Potter more times than we can count, most notably freeing the orphaned wizard from an awful life with his Muggle relatives and sacrificing his own life to preserve Harry's.
