Assorted Kate the Chaser headcanons (mostly post-proxying):
Lesbian (knew since she was super young)
Uses any pronouns, defaults to she/her, but the longer she’s been an proxy, the more she’s also come to favor it/its
Been a proxy the longest and therefore is the least physically human anymore (I’ll draw this later, but think emaciated, elongated limbs, claws, unnatural teeth, huge eyes, etc)
Eyes can no longer tolerate much light, prolonged exposure to even overcast days causes extreme migraines
Was hopelessly in love with Lauren
Slender controls her by making her hallucinate Lauren who then gives her Slender’s commands (is she a hallucination though? Or another proxy? Hmmmmm)
Can no longer speak, communicates in guttural noises and screams, though the longer she spends away from Slender the more she regains her cognizance to the point she can even write if left alone long enough
Has very little memory left of her previous life, can sometimes recall names or places but no idea who they were or what they mean
Outside of being incited into violence, she is a gentle giant who seems to be in a constant state of bedraggled weariness and grief
When she herself remembers what happened to her and her friends, she starts wailing this inhuman and deeply mournful sound which causes anyone who hears it to start crying, even if they don’t understand why. She can also cause an intense feeling of remorse or regret in anyone around her
Anyone she hunts is overcome with the base animalistic instinct to flee at all costs, forsaking literally anything else. Ignoring pain, terrain, logic, loved ones, anything.
Has sort of become like, almost a banshee like creature? Embodiment of remorse type thing
Even other proxies are not immune to her unconscious influence
The physically strongest/most powerful, but also most docile of the entities. She refuses to engage in violence unless directed, and is even rather skittish when not being influenced
Protective of Toby, but does not get along well with Tim or Brian (she’s sort of scared of them and tends to view them as a threat). Neutral towards Rake but will drive it out if it trespasses in her mines. Vehemently loathes HABIT and does everything in her power to avoid being around him for any reason, and will violently expel him from her physical vicinity when at all possible. Hasn’t met many other entities
Hates Slender from the very core of her being, does everything she can to defy him even in the smallest of ways at every opportunity. It’s been incredibly hard for her to have to watch him victimize more and more people, and she hates him more for it each time.
(I’m calling them entities for convenience’s sake, I know some of them aren’t proxies, etc. Bare with me, I haven’t actively been in the fandom since like 2015 and entities seems like the best catch-all)
