Dark Valefor
Dark Valefor is one of the Dark Aeons and spawns after you have obtained the airship Fahrenheit. Many gamers encounter Dark Valefor accidentally if or when they return to Besaid Village later in the game. Most then experience a very quick defeat at the hands of the powerful Dark Aeon!
Note that the Dark Aeons only appear in the International, PAL, and HD Remaster versions of Final Fantasy X. They are not present in the original North American PlayStation 2 release.
Note that if you are attempting to return to Besaid Village, either to recruit Blitzball players or to obtain the
Jecht Sphere near Besaid Temple, you will not be able to get past Dark Valefor without defeating it. There is no way to get by it.
Location
As mentioned above, you can find Dark Valefor in Besaid Village. A Yevon Acolyte will ambush you and summon the creature to attack your party.
Battle Preparation
Each of the Dark Aeons, including Dark Valefor, is considered a superboss, and they are some of the strongest enemies that you can fight in the game. As such, you will need to ensure that your party is fully leveled, has their best weapons, and has their stats maximized as much as possible.

Battle Strategy
Dark Valefor is the easiest of the Dark Aeons to defeat. Most of its attacks will do relatively minor damage except its Overdrive ability, Energy Blast, which can deal very heavy damage.
Make sure that you cast
Auto-Life on each of your characters for when Energy Blast comes up. Alternatively, you can have Yuna summon an Aeon who can take the blow for you (which will then KO that Aeon instantly).

You can Steal the following items during the battle:
And Dark Valefor will drop the following items when it is defeated:
Dark Matter (common)
Master Sphere (rare)
Dark Valefor will also always drop a weapon or piece of armor with three or four ability slots. Her weapons can include abilities such as Break Damage Limit and First Strike, while her armor can include Ribbon, Break HP Limit, and Auto-Regen.
