During the Hundred's year war with the monster known as Calamity Ganon, the people of Hyrule dug up the Divine Beasts under order by King Rhoam. The Divine Beasts were created by the Sheikah 10,000 years prior to seal the Malice: Ruto the water elephant, Rudania the fire salamander, Medoh the wind eagle, and Naboris the thunder camel. With the Divine Beasts at their side, the kingdom of Hyrule appeared to have taken the upper hand against the dark lord and his army of monsters.
However, little to the kingdom's knowledge, Ganon was wary of the Divine Beasts attempt to seal it again and spread its Malice across the Guardians and Divine Beasts, in an event known as the Great Calamity. From the Malice of the Divine Beasts emerged the Blight Ganons, who succeeded in killing the Champions that piloted each of the Divine Beasts. This allowed Calamity Ganon to rise and spread its Malice across the land of Hyrule, using both the Guardians and the four Beasts against their creators: Ruta created an endless rainstorm that threatens to flood Hyrule, Rudania caused Death Mountain to erupt continuously, Medoh caused unstable winds and threatens to shoot down the Rito when they flew, and Naboris caused massive electric sandstorms as it roamed across the desert.
When Link awoke from the Shrine of Resurrection 100 years later, he is sent on a quest by Zelda to reclaim the Divine Beasts in hope to seal away Ganon once again. One by one, he is able to purge them from their Malice, defeat the Blight Ganons, and free the spirits of the fallen Champions, allowing them to reclaim the Divine Beasts and assist Link and Zelda seal away Ganon once again like they did 10,000 years prior.
However, should Link have skipped purging any of the Divine Beasts, Ganon will warp the remaining Blight Ganons of the infected Divine Beasts to Hyrule Castle to fight Link before facing him on itself.
The Champion's Ballad
In "The Champion's Ballad" DLC, Link can partake in quests that unlock more of his past relations with the Champions, leading to a rematch with each of the Blight Ganons. These copies of the Blight Ganons are phantasms born out of Link's lost memories and fears. Defeating each Blight Ganon upgrades Link's Champion abilities, reducing their cool-down period by half.
|“||Good luck! That thing is one of Ganon's own, and it plays dirty! It defeated me 100 years ago... but only because I was winging it. I can't believe I'm actually saying this... But you must avenge me, Link!||„|

|“||Watch yourself now! That ugly pain in the crag is Ganon's handiwork. Thing got the best of me a hundred years ago. Good luck, little guy! Go get 'im!||„|
|~ Daruk, on the Fireblight Ganon.|
|“||Stay on your edge, Link! This formidable adversary was made by Ganon and brought me to a warrior's demise 100 years ago. Do not allow this to be your end. Fight for your life... and its death!||„|
|~ Urbosa, on the Thunderblight Ganon.|
|“||Please take care. That... thing is one of Ganon's creations. I put up as much of a fight as I could, but it proved to be my demise 100 years ago... Regardless...I believe you are well prepared for this moment. I have faith in you!||„|

- Shooting an arrow into the Blight Ganons' eye stuns them long enough for Link to get a few hits in.
- Each Blight Ganon has two phases in their fights. In the first phase, they tend to only use their main weapons, while in the second phase, triggered once their health has dwindled halfway, they use their elemental powers more often.
- If Link ever leaves the Divine Beast during a Blight Ganon battle, they will not show up again until Link reenters the battle room.
- While the Blights are genderless, Revali refers to the Windblight Ganon as male in his dialogue: "His aim is dead on!"
