No draw is possible between the Almighty and any mere created being. Gandalf, though Christ-LIKE in character, is not Christ, whereas Aslan IS. Gandalf is one of the Maiar, angelic beings sent by Eru (=God) to serve His aims in Middle-Earth. And it does matter who the character "is," because Aslan IS Jesus Christ, the Second Person of the Blessed Trinity. Thus Gandalf, AND Saruman, AND Sauron, AND Morgoth, AND Elrond, AND Galadriel, could ALL gang up against Aslan, and He would swat them like bugs.
