  • She uses a Rift Frog profileicon Frog in one of her animations, along with Morgana BewitchingCircle Bewitching Morgana and Thresh DarkStarCircle Dark Star Thresh.

    • A side-by-side comparison can be seen here.


  • She was the first champion released in 2018.
  • During development, she was called Void ADC or "JohnClick", which is a play on John Wick.[1][2]
  • Her placeholder model was Lucian OriginalSquare Lucian's model colored purple.[3]
  • Initial concepts portrayed her as:[4]
    • An undead former member of Lucian OriginalSquare Lucian's "Purifiers".
    • A Vampire hunter turn Vampire.
    • A Void-enhanced human hunting Voidborn.
  • Her suit's "wings" used to be separate void creatures that were tagging along on her shoulders, but later on, it was decided to make them part of the creature that is her suit.[5]
  • The symbiotic relationship is possibly inspired by Ryūko Matoi & Senketsu from the anime "Kill la Kill".
  • The teaser released for Kai'Sa OriginalSquare Kai'Sa during patch V8.3 had Void Seeker Void Seeker appear from the wall to execute the Rift HeraldSquare Rift Herald when it despawned.
  • The original design goal was to create a run and gun feel marksman.[6]
  • Her ultimate had originally belonged to Xayah OriginalSquare Xayah, but had no condition and would forcibly return her to her starting position after a delay.[7]
  • Kai'Sa and Camille OriginalSquare Camille were originally one champion named Husk, the Hive Commander, a female mercenary from Zaun who was once Caitlyn OriginalSquare Caitlyn's partner before she defected after Caitlyn OriginalSquare Caitlyn paralyzed her in a shootout.[8]
  • One of the potential narrative directions that could have been taken with Kai'Sa OriginalSquare Kai'Sa was that she was apart of a new generation of Void creatures trying to emulate humans.[9]
  • One of her narrative directions was to introduce Kassadin OriginalSquare Kassadin's missing daughter to the game as a playable champion. [10].


  • She is 20 years old.
  • Kai'Sa is 169.6 cm (5’6”) high like her Kai'Sa KDACircle K/DA counterpart.
  • Kaisa is her given name, Kai'Sa is her adopted Void name.
  • Her symbiote can sustain her through the Void-spawns they kill by absorbing their essence, but that isn't really pleasing to her. After the earthquake she unwittingly caused, she scavenged leftover food from castaway sources in the catacombs— water skins, rotting fruit, etc. Now that she can get out from the underground, she likes eating what she can find around Shurima Crest icon Shurima, preferably peaches. But the suit has to feed too, and she is somewhat fearful of what it might do if she doesn't continue to hunt and sustain it.
    • Due to her symbiote, Kai'Sa is stronger than normal humans while gaining abilities like blasting Icathian Rain destructive energy, especially when wearing her helmet such as Killer Instinct rift-walking and empowered senses (like special vision that is either thermoreception or X-ray vision).
  • Despite common belief, Kaisa was never trapped in the Void itself, rather willingly stayed within a complex underground tunnel system between the massive Void rift that caused the earthquake of her lore and the surface of the Sai desert, sculpted through years by the spawns that breach from the rift.
  • The lines that decorate her face are tribal marks made out of Voidborn blood.
  • Unlike other beings exposed to the Void's influence, Kaisa was able to avoid its seething madness thanks to her suit's helmet, which allows her to safely remain within the vicinity of Void rifts and traverse the Void sane when Killer Instinct rift-walking.
  • It has been theorised that the creature whose part would later become her second skin belonged to the same species as Kha'Zix OriginalSquare Kha'Zix.
    • One of her quotes to him is "I know your tricks".
    • Both the symbiote and Kha'zix evolve to become stronger.
      • Both have the potential to become invisible and shoot more projectiles after certain evolutions.

  • Kassadin's, Malzahar's, and Kai'Sa's lores are intertwined:
    • Malzahar OriginalSquare Malzahar recklessly used his Void-derived powers and sacrifices to summon Voidborns against his detractors, and such summonings always caused violent earthquakes as the realms collided. In order to always have the Void sated, his cultists extorted villages for alternative means of sacrifice, such as goats, in exchange of avoiding devastation.
    • Kaisa unwittingly released the sacrificial goats meant for Malzahar's cultists into a Void-linked canyon as a prank to a transitting desert nomad, causing an earthquake that devastated her village, swallowing and killing all inhabitants except herself, who survived thanks to the symbiote-suit and learning the Voidborns' methods of predation.
    • Kassadin OriginalSquare Kassadin, unaware of the details of the village's events, blames Malzahar for the destruction of his home village and his wife and daughter's disappearance assuming they were sacrificed to the Void, swearing vengeance against Malzahar and arming himself to stop the Void from spreading on Runeterra. In fact, Malzahar was only indirectly responsible due to his cultist's pressuring presence in his village.
      • One of the narrative direction for Kai'Sa was to introduce Kassadin OriginalSquare Kassadin's daughter to the game as a playable champion. [11]
      • It is a commonly held player theory that is often teased to be the case by Riot writers that Kai'Sa is Kassadin's long lost daughter.[12]
    • Currently, the Void-transformed Kai'Sa takes upon herself the responsibility of preying upon Voidborns and protecting Runeterrans against their predation, despite Runeterrans' distrust.
  • Kai'Sa saved Ezreal OriginalSquare Ezreal when he was attacked by Void creatures. Ezreal later helped her fight them.
