Due to her symbiote, Kai'Sa is stronger than normal humans while gaining abilities like blasting destructive energy, especially when wearing her helmet like empowered senses (like special vision that is either thermoreception or X-ray vision).
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. Now that she can get out from the underground, she likes eating what she can find around Shurima, preferably peaches. After the earthquake she unwittingly caused, she scavenged leftover food from castaway sources in the catacombs- water skins, rotting fruit, etc.
Her symbiote can sustain her through the Void-spawns they kill by absorbing their essence, but that isn't really pleasing to her.
Kaisa is her given name, Kai'Sa is her adopted Void name.
Kai'Sa is 169.6 cm (5’6”) in height like her K/DA counterpart.
She was 10 when she fell into the Void tunnel and has stayed there for about 10 years.

They fought some void creatures together, including some of Rek'Sai's Xer'Sai.
Kai'Sa encountered Taliyah and her group on their journey to find Xolan, a mythical paradise in Sai Kahleek.
Kai'Sa saved Ezreal when he was attacked by Void creatures.
While their relationship in the main universe has not been formally confirmed, in the Music skins universe, Kassadin is K/DA Kai'Sa's father.
A popular theory held by players that are often implied to be the case by Rioters is that Kai'Sa is Kassadin's daughter.
Currently, the Void-altered Kai'Sa takes upon herself the responsibility of preying upon Voidborns and protecting Runeterrans against their predation, despite Runeterrans' distrust.
In fact, Malzahar was only indirectly responsible due to his cultist's pressuring presence in his village.
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.
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.
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.
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.
Kassadin's, Malzahar's, and Kai'Sa's lores are intertwined:.
