Nightmare Fuel / Far Cry Primal

Warchief Ull: Seven feet of hulking, cannibalistic Neanderthal come to ruin your whole day.

• Batari's death. After a long a difficult boss fight, Takkar holds her against the fire that her and the Izila worship. As a result, she slowly roasts to death over the fire that her cult worshipped. And you are made to watch it all in gruesome detail. Granted, Batari deserves it, but still...
• The opening mission. After Takkar and his hunting party have successfully tracked down and killed a woolly mammoth, a saber-toothed cat appears out of nowhere and starts killing Takkar's friends one by one, shrugging off a spear to its ear and nearly murdering Takkar himself, not to mention actually murdering his brother.
• Whenever your tamed beast is running towards you at night. Even though you know they're not running to attack you, it's still pretty jarring to see a gigantic cave bear with glowing eyes running at you.
• The page image is of Warchief Ull when he first attacks the Wenja village. This gigantic, thuggish tribe chieftain with a partially-burnt face shows up out of nowhere, attacks the villagers, and grabs Takkar himself in a two-handed Neck Lift when the hero impulsively attacks him, and rasps at him, "Softblood Wenja no stay. You leave. 'Or you DIE!!!" and then punches Takkar backwards several feat. Thankfully, you get revenge later, but Ull came this close to murdering Takkar on the spot.
• Takkar himself could be considered this. The Udam have been waging this war and winning for a long time, when this one Wenja softblood arrives. No big deal, just another hunk of flesh to eat. But then what happens? He reclaims the best and brightest of his tribe, and gives them a home to live in. You go there to offer your objections through the use of clubs and poison. Then he comes with beasts. The animals that can destroy an entire hunting party obey his commands. His weapons become more and more complex and polished and his tactics more and more intricate. Then he assaults your fort, then your homeland, alone and completely slaughters anyone he finds there. Though his own skill and tenacity, Takkar has single-handedly doomed whatever little hope your tribe had left. Taken even further if you clear the Outposts while remaining undetected. Do that consistently and Takkar has essentially become a force of nature. Your tribe in these outposts are all dying over the course of one afternoon... and you don't even know why.
• Bears have always been a staple of Far Cry. While the game does feature the traditional brown bear, it also has cave bears appear from time to time. These bears are much, MUCH larger than the brown bears and are big enough to take down a mammoth. What makes it even worse is when the bear comes in contact with other cavemen, often snatching them in its mouth and shaking them like rag dolls.
• Mammoths. While they do tend to be rather docile for the most part, when threatened or injured, they will come after the player. And by they, the entire herd.
• The predatory fauna in general, especially at night. You've just led a group of Wenja to a small campsite as night creeps in. It's too dangerous to leave, and you may think you're safe. Then the wolves come. You can spend the rest of the night fighting off packs of wolves and they slowly and surely pick off everyone else.
• In one area of Oros, you can find a batch of glowing purple eggs next to the impaled skeleton of a Blood Dragon. Yes, those Blood Dragons. Admittedly, the Dragon's a lot less scary since it's dead, but how did it get there in the first place? Who (or what) killed it? And how long have those eggs been incubating? Are there any more Blood Dragons somewhere in the Oros? These questions remain unanswered.
• You'd think that being a valley in prehistoric Central Europe, you wouldn't have to worry about crocodiles like you did in the last two Far Cry games. You'd be wrong. Like the Kyrati mugger crocodiles, they're not that common, but they are there, and they're one of the rare creatures that Takkar can't tame, along with eagles.
• The Demon Fish from Far Cry 4 reappear, this time as "Bitefish". They patrol the waterways of Oros, and whereas harvesting crocodile skins is optional for Takkar, harvesting bitefish skins is a necessity for Urki's first mission. Which means Takkar will have to get in the water and swim around until a bitefish comes for him... or he can just get hold of a bow and snipe it from the land.
• A lot of Takkar's allies are pretty disturbing. Sayla is Hearing Voices of her dead loved ones, and is obsessed with cutting off Udam ears, to the point that she'll venture into the cave of the Bloodfang Tiger just to collect them from his victims. Tensay frequently makes Takkar drink Squicky blood potions full of human parts, including eyeballs. And Wogah had one of his arms cut off and eaten by the Udam. And it wasn't a clean cut either: you can still see the bone sticking out of his upper arm.
• If you needed a reminder of the brutality of prehistoric brain surgery, at one point, Dah is having a violent "skull fire"-induced headache, and begs Takkar to let some air in to "cool skull". Takkar presses a bone dagger against the top of Dah's head and has to literally hammer it home, accompanied by sprays of blood and screams of pain from Dah. And then after his headache recedes, Dah laughs in an extremely creepy way and stands up to thank Takkar, ignoring all the fresh blood running down his face.
• We're first introduced to Batari and the Izila when Takkar finds Tensay tending to a screaming Wenja whose skin was horrifically burnt by Izila fire weapons, to the point where Tensay has to snap his neck to put him out of his misery. When Takkar reaches the outskirts of the Izila village, he sees Batari confronting two of her captives, an Udam and a Wenja. She draws a knife and cuts the Udam's balls off, mocking his screams of pain and ordering him to scream louder. The poor Udam most likely dies after that. This Establishing Character Moment solidly shows that Batari is a more threatening antagonist than Ull.
• The Stinger with Ull's older child where we learn that they, too, are a Beast Master. And how do we learn this? We see them taming a massive cave bear. This is disturbing for two reasons, the first, that they're a small girl alone with a massive cave bear, and second, that their way of taming said bear is a lot fiercer than what Takkar does, shouting and growling a lot like that bear, in contrast to Takkar's soothing whispers. Granted, this more properly qualifies as an Awesome moment, but still, creepy. And then there's the Mood Whiplash of Ull's child giggling at the Smash to Black.
• The "Legend of the Mammoth" DLC features a creepy spirit rhinoceros that the titular mammoth has to track down and kill. In contrast to the normal rhinos that Takkar bumps into, this one is pure black with glowing red parts- including its eyes and horns- and has a habit of vanishing and reappearing whenever you hit it enough. Just what is this thing?!
