LIES
Well shit... I forgot about her... Yeah that one makes a LOT of sense... Kinda scary too.
Aye, Zed/Syndra comic season 1
I think I've read it but its been awhile. XD
Though I joined on patch 5.6 so don't think I'm some kind of vet. I just like looking around for old stuff.
Who is that?
Its Syndra.
Personally I like this one better. http://pre05.deviantart.net/2259/th/pre/i/2014/324/9/d/syndra_trance_by_prismacube-d872ar5.png
Darn it... I should have seen it coming.
But yes I do think that https://s-media-cache-ak0.pinimg.com/736x/76/d4/57/76d457fa9f428a8f61f879ffa93bf200.jpg could be. =P
Going through the list in my head...If she became infatuated,
seems very capable of having the most severe case. Everything in her lore and in-game speech together tends to give the impression she's not quite intact after the whole "forced into giving up any and all previous hopes, then forcibly being turned into a child soldier with a family that does not care, at all" thing. Like, deep-down, she actually believes the exact opposite of everything she says about staying positive on the battlefield and the like.
Yeah, I can see that. If there's ever some sort of "Unhinged Lux" skin motif, I can't say I wouldn't understand.
Omega Squad 
I mean, Omega Squad
talks to his Mushroom. Thats some serious unhinging right there. Hell even his lore tells it all he is warped and completely batshit insane.
points, intrigued Now you're talking. And given the theme of the thread, Yandere Lux seems a little more realizable. It's a little late for me to be thinking creatively, but I can see a slightly...darker Lux. Or, at least, a little more openly so.
Lux for sure. Her voice sounds like a yandere.

So like, was Gifrolling prominent before I did it or did I make a new meme? o.o
