Protean is also the vampiric discipline of shapeshifting in the Vampire: The Masquerade role-playing game, and is the unique discipline of Clan Gangrel. Protean allows the user to see in the dark with glowing red eyes, grow tough claws that do aggravated damage (called wolf claws), turn into the legendary cloud of mist, or sink into the ground to escape enemies or the rays of the sun. Protean also allows one to shift into the forms of any two animals, most commonly a wolf or a bat, though some users of Protean can assume the forms of different animals (to quote the Gangrel clanbook, "you turn into what you expect to turn into").
