Lady Yunalesca is an antagonist NPC in FFX and FFX-2 who brought about the Calm, becoming the first summoner to beat Sin in the process. She is a peculiar looking thing, and has long silver hair that sprouts from her head in all directions. She also has yellow eyes, is scantily clad, and wears an extravagant headdress. 

In FFX, Lady Yunalesca’s story begins with the creation of Sin by Yu Yevon, who is actually Yunalesca’s father. During this time, Yunalesca escaped Zanarkand with her husband (Zaon) after Sin left the city in complete ruins.

Yunalesca then began a quest to defeat Sin, and succeeded in doing so. Becoming an Unsent entity after performing the Final Summoning, Yunalesca’s spirit remained in Zanarkand to guide future summoners in their pilgrimages.  

Who were Lady Yunalesca’s guardians? 

As far as we know, only one guardian is mentioned in regards to Lady Yunalesca’s quest to defeat Sin. This guardian was Zaon, her husband. 

Not much is known about Zaon other than the fact that he was sacrificed by Yunalesca to create the Final Aeon and defeat Sin. In doing so, Zaon also became Sin’s first ever victim, and also brought about the Calm.

Yuna is, in fact, named after Lady Yunalesca. As the first ever summoner to be victorious against Sin, Lady Yunalesca was a highly influential and popular figure throughout the whole of Spira. 

This is believed to be the main reason why Braska named his daughter Yuna.

Yunalesca is one of the hardest battles in the whole of Final Fantasy X. There are a few ways to beat her, however, and if you have a gameplan before you go into the fight, you’re likely to come out the victor. 

The best way is to keep all of your characters healed to full health, and to keep 2 out of 3 of the party zombified. It’s absolutely essential that you field a character with the Zombie ability. 

When Yunalesca performs Mega Death, simply revive the fallen character, use Holy Water on the zombified characters, and heal them all to full health. Then you’ll have the chance to deal some real damage to Lady Yunalesca. Rinse and repeat. 

Aside from the keeping on top of the Zombie status, you’ll also want to equip Confuseproof to as many characters as possible, but at the very least the character who will be delivering most of the status magic effects.  

Another tip is to get all of your aeons ready with their overdrives prior to entering the battle. Then when Lady Yunalesca reaches her 3rd and final stage, unleash the aeon overdrive power and watch her struggle to deal with the power. 

Is Lady Yunalesca the final boss?

Lady Yunalesca is not the final boss in Final Fantasy X. Yu Yevon is the final boss you will encounter before the end of the game, though many players believe Braska’s Final Aeon to be the real final boss in FFX as the Yu Yevon boss battle is largely cinematic.  

Why did Yunalesca kill Auron?

Yunalesca mortally wounded Auron during Braska’s quest to defeat Sin. This happened after Braska sacrificed Jecht as a Final Aeon in order to carry out the Final Summoning. Auron interjected, and was punished by Yunalesca for his disruption. 

Auron managed to live long enough to entrust Yuna into Kimahri’s care, before dying from the damage dealt to him by Yunalesca. 

The Auron we see for most of the game is the Unsent Auron, meaning that it is the spiritual form of Auron made up of pyreflies because his spirit has not yet entered the Farplane.
