The only reason it would matter is kinda two-fold.
Titan would seem like a good idea here... the difference however is the timing of its execution (he takes a while to be summoned). If you really wanted to expose the behavior efficiently, you'd go straight to Chocobo while his cloak is down and have fun. The whole point is the demonstration of the his cloak...
Unfortunately, Bio is cheaper, easier, and much more reliable. Go figure. You would pretty much avoid most of the strangeness.
Sorry for the untimely answer.
You are better off making Edge or Rydia cast a Fire elemental magic for some hilarity after being blown up by his special fire attack.
