A theory on why Kai'sa looks so "normal"
There's been some controversy on the boards on how non-monstrous and unmutated Kai'sa looks after surviving so long in the void. I mean Kass and Malz merely glimpsed the void and there were noticeable physical changes to them.
After thinking for a while, I started to wonder on whether she actually survived.
What if she died almost immediately and the "second skin" reanimated her to act as SOMA-eqse corpse puppet to harvest other void creatures for it to devour. The void energies she's constantly exposed to being consumed as life support and so there's little left to mutate her. There's even a good reason for the skin to reanimate her mind too, the skin gets the benefits of all her survival instincts and intelligence at no real cost to itself as she's gonna kill void creatures regardless, hijacking the human instinct of "KILL IT WITH FIRE [power]"
