No, just strengthen your characters until you are able to kill off that Dark Aeon. Dark Valefor only has 800,000 hit points, Attack Reels or Blitz Ace with a Break Damage Limit weapon might be able to kill it with one hit. Just give someone a First Strike weapon, and switch Wakka or Tidus into the battle as soon as it starts, then use the overdrive.

Or strengthen an Aeon (Bahumut probably) so he can go head-to-head with the Dark Valefor.

Or just summon Yojimbo and give him lots of money, and hope for Zanmato.
