Sphinx is an ancient but not unathletic Egyptian hero with gangly arms and a lion's tail. Tut, short for Tutankhamen, is a goofy prince turned into a mummy before his time by an evil brother -- but being a mummy has certain advantages.
Since he is already dead, Tut doesn't worry about dying. Need to fit through a tight gap? Crush Tut and send his paper-thin corpse through the niche. Is there a wooden barricade blocking that next doorway? Torch Tut and he can burn that junk out of the way.
Electric eels in the waters around your town? Broken machinery that needs a charge to get going? Not only can Tut withstand the shock, he can conduct it. He can even be in three places at one time through the magic of amputation. He can even go up in smoke -- very handy for searching the world.
