Playing with the big bad boss isn't as great as you'd think.  In fact, Gargos is just like the others, with the same general attacks.  He can fly.....but why would you want to make him fly?  He also laughs and flaps his wings.   The computer-Gargos regains his energy while flapping his wings.  While we can't regain our energy, there is a use for flapping Gargos' wings.  It reflects fireballs.  Trust me on this!
