Dark Ixion (Final Fantasy X)

Dark Ixion is an optional boss in the International and PAL versions of Final Fantasy X. It can be encountered twice, first time by talking to a Yevon soldier on Thunder Plains, and after that, by finding him after a lightning strike in the northern section.

Strategy
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. As in the other Dark Aeon battles, it's 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. 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 you have a relatively weak party that would die after one hit of any of Dark Ixion's moves, equip two characters with Auto-Phoenix. If you bring out an aeon when Dark Ixion's overdrive gauge is full in the second battle, you'll 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, remember Dark Ixion counters.

After Dark Ixion is defeated, and during the second battle, it is noticeable that Dark Ixion no longer has counter attack, making the second battle far easier than the first, but most of the original strategy applies.

As any other enemy, both times it can be killed instantly by Yojimbo;s Zanmato attack.
