Dark Ixion is one of the Dark Aeons and spawns after you have obtained the airship Fahrenheit. Dark Ixion can be found in the Thunder Plains and defeating it involves challenging it to two separate fights.
Head back to the Thunder Plains and head in to the northern section and look for a Yevon soldier. After you defeat Dark Ixion for the first time, you will have to seek it out one more time. Ixion will spawn very close to the party after the next lightning strike.
Each of the Dark Aeons, including Dark Ixion, are considered superbosses and 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 levelled, has their best weapons and has their stats maximized as much as possible. Refer to the Advanced area of the Tips and Tricks section for additional details.
