let me preface this by saying I haven't read Monstrous, that new lore story that was leaked. IK it exist and that some of the points ur making are derived from it, but I and I wouldn't advice anyone else to read it or make any arguments based off of it, because its still liable to be changed until its released, either granting new evidence or TAKING AWAY evidence that ur arguments relied on, basically im saying u can't use it for anything until its officially released. Look i see ur points and if they release Monstrous in a state that still validates ur points then u have my full support, but until then i would rely on something that isn't official yet.
That aside thanks for redefining what a Mary sue is, i'll be sure not to make the same mistake again
That aside the suit affecting her mentally hasn't been explored in a way that is officially released besides, it warning her from danger of nearby threats, or when its hungry. In that way its effectively works like Spidermans spidey-sense but it takes SUCH a back seat to everything else for how important it or useful it is in the Lore and gameplay that it doesn't feel like a very impactful part of the relationship between Kai'sa and the void suit.
"Even without manipulation, the suit simply being alive can be enough to help a mental state of someone, that they aren't truly alone." This has not been officially explored, its just speculation. Kai'sa doesn't treat the suit's mental presence like a anchor that keeps her from feeling lonely; from what I have read in the lore, the suits mental/nervous-system presence is either treated like a warning system or a threat that it needs to be fed, nothing else. Not that I wouldn't LOVE to agree with you, for kai'sa to show that she isn't infallible for all that time alone, but it currently doesn't exist beyond speculation at this point.
Ur point about Kai'sa and the suit working together is valid, excuse my oversight, we all have our biases and tinted view points, thanks for adjusting mine.
On a next point, it is interesting to note that nothing in Kai'sa's lore is told from the Voidsuits point of view, Kai'sa has to infer what it thinks or feels and has learned its patterns, but she had none of this info when it first attached to her; when it was seemingly dead but tingled to the touch. So while we know that Voidlings first objective is to consume and second to survive, we cannot infer that eating Kai'sa would have meant it would die, we also can't infer that it would have been smart enough to KNOW that eating kai'sa would have killed itself (IF that WAS indeed going to happen), because we kno that young Voidlings do not have a high amount of intelligence, they operate on pure instinct following their 1st two objectives until they grow older. Thus having the brains to make an intelligent decision is something that this young voidling would not have possessed, it can only operate on instinct, and that means consuming 1st and surviving second. But we ALSO kno that Void energy corrupts organic matter and turns it into Voidlings, with this in mind, acidifying Kai'sa's arm and turning it into the Voidlings own biomass to regain its vitality is most likely way that it could have achieved both of its objectives, and thats what it should have done knowing what we know about Voidlings.
That aside; again we don't know what was going through the Voidlings underdeveloped mind, so again saying it "choose between survival or a kill" is just speculation. Why choose between killing and survival when its entirely possible and we KNO that based on Kha'zix and her comic that Void-related-things can do BOTH at the same time.
In the state that Kai'sa and the suit are in NOW, yeah i can see that Void-suit having had its intelligence developed to the point where it can make these types of decisions, i could see it deciding to work with kai'sa for its optimal survival sense she also feeds it whenever it demands to be fed. Its likely smart enough to know that its basically getting food for half the amount of work. I can make this hypothesis based off its likely level of intelligence because its backed by the fact that Voidlings grow in intelligence the longer they are alive. But once Kai'sa outlives her usefulness or is crippled such that it cannot feed the Suit anymore it will likely eat her in a heartbeat, and use her biomass to evolve and resume its normal life. And again it wouldn't have this lvl of intelligence as a small young voidling.
The biggest issue I have with Kai'sa isn't that the Suit does all the work, (thanks for clarifying that ealier but it still wasn't my biggest issue with her)
Its first her incredible amount of luck with the Voidling not immediately eating her arm, based on what we know about voidling and THEN that fact not being explained at ALL, and also how this young voidling knew exactly how to joints so her mobility was preserved.
And second its her surviving in Void-infested caverns for any amount of time longer than 3 days to a week, and coming out nearly completely unscathed mentally or physically,
Third, how the suits contribution or symbiotic/parasitic relationship takes SUCH a backseat to everything else in every aspect of her that the theme of a Void Symbiote or parasite is as wasted on her as the theme of flying blades was on Old Irelia.
Fourth how they decided to focus more on her eye-candy which is at complete odds with her whole story and theme, and also isn't explained.
