#Jusr a tiny bit obsessed with horror siren sans now

[palettepainter]

I’ll be posting a little writing WIP for Hired Sparky later today, but for the Undertale fandom, may I propose an idea with Siren Horror?

I’m a shameless fan of HTTYD and the Sea Beast and 2024 I am dubbing my year of self indulgence so I’m posting this. I might write this if it’s popular enough or if I get the confidence too, but imagine: 

Y/N as a newcomer to a seaside town, neatly nestled on a coastline in the middle of nowhere. It’s bitterly cold nearly all year, and the people are about as sweet as vinegar. But the housing is dirt cheap, considering the looking threat of sirens that infest the waters. Y/N is nearly dirt broke and is looking to build a life outside of their family home, so the unwelcome seaside town it is! Not many people are willing to go fishing in waters popular for siren sightings, so the pay is pretty impressive (even if the work field is a bit competitive at times)

They’re hired onto a boat crew of hardened fishermen who all retell gorey tales of siren attacks in great detail fairly quickly, after doing a bit of research on sirens. The crew are at the point where they’ve learnt to laugh a little, they’ve worked the job long enough that they’re pretty relaxed despite the looming threat of danger on the water. Y/N is not so eased. They’re hired purely as a second hands on the boat: tending to nets and sorting fish once they’ve hauled onto the boat, nothing else. But the captain still hands them a rather heavy harpoon gun with permission to fire if need be. 

They set off into deeper waters where few fishing boats are given the clear to fish, meaning it’s basically free game for anybody with a net to catch fish of all kind. The weather is rough, but the crew bat their hands and say they’ve faced down worse storms 

But then a siren is spotted breaching the water a little ways from the boat. They’re not in immediate danger, and so reader assumes they’ll simply sail out of its line of sight, but the crew already fire a warning harpoon into the water to try and scare it off. For a beat, there is nothing, before the siren attacks the ship - a kraken of all things, one of the most dangerous species, considering its ability to grasp at the ship 

The harpoon has wedged itself into the creatures skull, piercing through the top and dimming it’s eye lights. It screeching, in confusion or anger, maybe it’s the panic coursing through their system, but the protagonist thinks that maybe, their might be fear mixed in with that shrieking. More harpoons and swords are fired at its heaving body, chipping at already injured and cracked parts.

When Y/N is ordered to shoot they instead aim for the rope attached to the end of the harpoon wedged in the creatures head, it grazes the rope, but it’s enough for the creature to snap is with a violently throw of its head. The creature sinks back into the water, the boat tossing from the loss of its weight, sending many of the crew overboard - including reader 

They try to swim back to the boat, but swimming in the confines of a pool to practise swimming in the sea proves that the sea is far more ruthless. They end up being dragged out to sea, climbing to a part of the boat railing that had been snapped off during the attack. Reader wakes up in some kind of enclosed cavern like structure, obviously forged overtime from the waves chipping away at the rocks. They’re cold, hungry, terrified…but alive. And they learn quickly they’re not alone. The siren is nearby, confused, disoriented and greatly weakened from the spear still stuck in their head. They can barely keep their head upright before they topple back into the shallow water with a grunt of exhaustion 

It takes a bit of effort, and gently coaxing, and a hell of a lot of stupid bravery, but when the siren has tired itself out enough and after several failed attempts at trying to swat them away (missing mostly each time thanks to their vision being heavily impaired from their injury) but eventually, the reader dislodges the spear, and is then promptly smacked *hard* and is sent flying into the sand 

Reader is certain they heard something snap as they fall back onto the sand, but miraculously, they don’t collide back onto any rocks. Feeling sore, they sit up, the siren is supporting itself on an arm with laboured breaths, the other clasping at the eye socket on the injured side of its head. Gradually, a red, focused eye light burns to life, focused dead on them. The siren looks at them curiously, as if they’re only just realising it’s alone - Y/N expects an attack, for it to pounce, so something…instead, the siren snorts, shakily hobbling off to the were the water is deepest 

Basically: what if Reader was THERE when Sans got that injury on his head?? The two have been washed into a cove by the tides: Sans is too exhausted to climb out and the water is dangerously shallow, there isn’t enough food for him to sustain himself, and without it, he won’t heal. Reader goes through the whole “Maybe these monsters are only monsters because we chose to see them that way” and overtime the two form a somewhat bond, reader bringing Horror food and such while he heals and Horror showing them that sirens are far more intelligent than what silly books have documented about them 

I’m a sucker for enemies of two separate tribes or species breaking the generational hate and learning to be friends it is SUCH a good dynamic and it scratches my brain the perfect way
