And Pan never fails...interesting to see how the actor who plays Henry handles the character of Pan. He has a lot to live up to!
Pan's whole power seems to come from basically...his ego, or at least other peoples' perception of him. He basically keeps repeating how unbeatable he is because it makes everyone think he is and he draws his power from that.
If he ran into someone whose willpower and self-confidence was so assured that they kept thinking 'Nah, you're dead meat.' then he'd be screwed.
