Dark Ixion is an optional boss in the International and PAL versions of Final Fantasy X. It is encountered twice, the first time by talking to a Yevon soldier on the Thunder Plains, and after that, by finding him after a lightning strike in the northern section.
In the first battle, Dark Ixion counters every attack, and may cause Sleep, Armor Break, and Mental Break. His non-elemental Thundaja spell also may be dangerous, usually dealing 99,999 damage per shot. As in the other Dark Aeon battles, it is best to use Auto-Life or call an Aeon when the enemy's Overdrive gauge is full, as although his Overdrive is quite weak, occasionally not even dealing five digit damage, it inflicts Full Break, which can be cured by using Dispel.
In the first battle however, he only uses Aerospark when his Overdrive is full. Dark Ixion has low HP, so it can be defeated quickly using the strongest Overdrives several times. The party should have extremely high Agility and Luck. Very high Strength, Defense, and Magic Defense are also very useful.
If the player has a relatively weak party that would die after one hit of any of Dark Ixion's moves, equip two characters with Auto-Phoenix. If the player brings out an Aeon when Dark Ixion's overdrive gauge is full in the second battle, they will be fine as Dark Ixion has no other attack that attacks more than one opponent. It will take a while, but simply using strong physical attacks will help, however, Dark Ixion will counter.
After Dark Ixion is defeated, and during the second battle, it is noticeable that Dark Ixion can no longer counter, and his attacks now inflict Confusion and Petrify. This battle is much easier than the first, and most of the original strategy applies.
As with any other enemy, both times it can be killed instantly by Yojimbo's Zanmato. Please note that because Dark Ixion is resistant to Overdrives, the player is likely to have more success with potent basic attacks.
