Yandere Gregor Clegane/The Mountain (general)

-Gregor Clegane is a monster of a man both in height and actions, even before Qyburn gets a hold of him. He has no care for anyone or anything, particularly the weak and poor, and his terrifying temper knows no bounds. He'll lash out at anyone and or anything in his wake, it doesn't matter who's around to witness it.

-It doesn't help that he suffers with migraines, causing him to be even more temperamental and violent. Especially when he wants nothing more than some quiet. He is never not without these migraines of his, the severity of them being the only thing that changes. Resulting in Gregor consuming massive amounts of milk of the poppy, so much so he's built an immunity to its side affects. Well, a majority of them at the very least. Not to mention it takes away from him feeling any pain. Not that much wouldn't effect him anyway.

-Gregor is not gentle, nor caring of his obsession. If anything he's only tolerable of them but that's enough to keep you safe from his wrath. For now. I can see his obsession stemming from his darling's voice. Maybe it's light and airy. Or smooth and soothing. Either way it's the first thing that catches his attention. It's the only sound that doesn't hurt to hear or make him want to bash your skull in a blind rage. That one thing is enough to have Gregor Clegane keeping an eye on you.

-As long as you don't do anything to garner Gregor's anger, which is asking a lot, you won't be harmed. Given that he has a liking for your voice, you maybe let off the hook in terms of small and insignificant mishaps. It's only the fact that you're beneficial to him that Gregor can be more conscious of his actions and behavior towards you. But that doesn't mean you're excluded from punishment. No, he can and he will still punish you.

-The only way you could be safe from punishments is if you were not in Gregor's possession. And that can be possible. Gregor's only real interest in you is that your voice means something to him. He doesn't know what or why but he likes it. He has no intentions of taking you or even interacting with you at all. Not in the beginning. But eventually it gets to a point where your voice is the only voice he hears clearly. He can pick it out of a crowd like nothing. Soon enough he's finding himself at the same places you are or frequent. It's hard not to notice him. Thankfully you can see him coming and take your leave if need be but you better be quick about it.

-Honestly, you probably aren't aware of Gregor's interest and who could blame you? It's not like he shows it or makes it known in any way. He isn't quite sure what he feels or what he's doing. If you did catch onto him being around you more or something of the sort, you should run as fast as possible. Especially if you want to protect the people you care about. Get the hell out of Westeros. Get the hell away from him. I mean, the most Gregor would do for you is killing anyone who is/gets too close or is in the way. But that's not really anything new. The only difference is that said people had interactions or connections with you. And he found their existence to be a nuisance.

-It would take Gregor not hearing your voice for awhile before it effects him. He's grown so use to the sound and hearing it every so often that it seems foreign not to have it. It's almost as if he starts to go through withdrawls. Once he starts feeling like this he gets more aggressive and even more violent. He has no tolerance for anything, let alone anyone. It doesn't help that he doesn't understand what he's feeling, all he knows is that he needs to find you.

-If you've fled the city already and are far enough away from him, Gregor will try to find someone who can replace you. But it's not the same. They're not the same. If that's the case then he has no need for them anymore. And we all know what he does to worthless things, right?

-It would probably be by complete coincidence that he happened upon you again. Your voice was a dead give away, him following the sound the second he heard it. It doesn't matter what he's in the middle of doing, he'll toss it aside to go in search of you. And once he does find you, having you in his sights, he knows he's not leaving without you. Not like anyone could stop him anyway. And who's to know what you're fate will be like now that he finally has you.

-I could also see Gregor purposely going out of his way to take his brother, Sandor's obsession. Or rather anyone Sandor is close to/cares for. He does it more so just so Sandor won't have them anymore. In this scenario, Gregor is much more inclined to break and ruin "his" darling, just to take them completely away from Sandor. In every way possible. Or at the very least he'll make them into damaged goods.
