What I was to her, she was to me. You can never understand.
– Dark Kaia, 14.03 The Scar
A doppelgänger version of Kaia Nieves from the Bad Place, who like her counterpart is a dreamwalker. She appears to be highly adept at using her main weapon: a long spear made of bone and stone. Kaia and Dark Kaia's powers kept them connected their whole lives -- each one saw what the other experienced in their world.
Kaia Nieves' doppelgänger appears as a cloaked figure stalking through the Bad Place whenever Kaia is taken to it. When Jack and Kaia join their powers to try and open a rift to escape the attacking angels, Kaia begins losing her hold on Apocalypse World, going back to the Bad Place where the cloaked figure begins advancing on Kaia until Kaia and Jack let out a blast of energy, destroying the angels and sending Sam and Dean to the Bad Place.
While Sam and Dean are trapped in the Bad Place, the hooded figure is seen following them. Later, the figure catches up to Sam and Dean and knocks them out with a spear. When they wake up, they are tied to tree trunks. The hooded figure returns and bangs a nearby giant monster skull with the spear, attracting the attention of the Kaiju.
When Claire and Kaia find and free Sam and Dean they take them to the nearby rift. Soon, the hooded figure catches up and throws the spear at Claire, but she is pushed out of the way by Kaia who takes the hit and dies. Claire tries to go after the figure, but Sam and Dean drag her back through the rift before the Kaiju arrives.
Later at a park in Sioux Falls, another rift opens and the cloaked figure passes through and removes the hood, revealing Kaia's face.
