3rd person POV:

It's been 9 years and (y/n) is now 25 years old. She's still been trapped by "that old fart " who stole her from the ocean and stopped her revenge.
Today was like any other day, and (y/n) continued to stare out of her tank at the window blankly, refusing to talk to the man as usual.

He was throwing her food into the tank when suddenly the whole ship started to shake like it did the day her family was destroyed.

The man stopped and ran out to go investigate what it was, leaving the tank open on accident.

(Y/N) POV:

I saw my chance to escape when that wretched man ran out of the room. I swam up as fast as I could in the small space of my tank and burst through the opening, jumping out of the water and landing on the cold metal floor. But I didn't sulk on my pain for too long, I figured I didn't have much time.

I drug myself across the dirty floor, shivering against the feeling of sand and other things getting stuck on my (f/c) scales and fins. Seriously does this man even know what a broom is?!

I could see the door, but it was too high for me to reach from my position on the ground. I decided to take a risk by taking the time to drag myself around his filthy floor even more until I'd collected enough things to give me a boost so I could reach the handle.

As soon and it opens a wave of water crashes into the ship pushing me back a bit. I revel in the feeling of the ocean water I've missed so much as I drag myself against the coursing river that's flooding the ship until I can finally slip out of this damed hell hole that's kept me captive for almost a decade.

I was Free! Absolutely FREE!! It felt great! I let out a laugh of joy as I swam as fast as I could, brushing myself off from his filth as well. Speaking of which, I think it's time I "thank" him for all the pain he's put me through!

I searched the entire ocean until I found him in the Safe Shallows, he was standing on a tiny hill staring at yet another crashed ship, and this one was WAY bigger than the one that destroyed my home! But I couldn't just sit there gawking at it, I knew of a reaper leviathan that lived around here and I knew how violently they tore their victims apart! I evilly smirked as I swam towards it , planning to lure it towards the man and let it have him.

I cringed as I swam through the radiation of the crash. Finally I found the reaper leviathan swimming around the flaming crash. A small feeling of fear washed over me, but I suppressed it feeling that my revenge was far more important than my safety at the moment. It seems that the reaper leviathan was already pissed for losing its home and I watched as it attacked whatever swam near. Perfect! Now all I needed to do was out swim it and lure it to the man!

I picked up a near by rock, sizing it up before throwing it towards the reapers eyes. I will say, nine years locked away and my aim is still second to none!

The rock slams into its eye and the massive creature erupts from its agitated swim into an angry temper and bolts towards me! I make a b-line away from the monster straight towards the man.

The dumb fools' back is turned! Ha, he'll have no clue! I swerve upright when I'm about to collide with the man and the monster tackles him!

His screams of agony are like a symphony in my ears and his blood paints a beautiful picture in my eyes! He's finally gone! I've killed him!

------TIME SKIP BECAUSE I CAN------

It's been a good 5 weeks since the crash of that giant ship! I've continued my revenge towards humans by luring sea creatures to destroy those life pods that were all over the place. There was one right by the crash but I let it be since it seemed deserted.

I wish I had my powers! It would be so much faster to destroy them! I scratched once more at the restraining necklace around my neck.

The thing was, even though I'd killed all the humans I could find from this new crash, I don't think many made it out of the actual ship in time before the explosion. Well I suppose that's good. Makes my job easier!

I was swimming through the Crag Field when I heard some thumping and... shouts of glee mixed with ... curse words?

"GET BACK HERE YOU BLADDER BITCH! IMA PUNCH YOU WITH MY CYCLOPS!!! I'LL PUNCH YOU STRAIGHT IN YOUR GABBA!!!! I SWEAR ON ME MUM!!!"

Who the hell was that?! What's a 'cyclops' and a 'gabba' ? Suddenly a bladderfish burst from between the spires of rock and swam off like it was in fear of it's life!

I swam closer to investigate when suddenly one of the large rock spikes exploded! I tried to swim away but I was hit on the head by a chunk of the rocks.

My body was being bombarded by the falling rubble. The last thing I saw and heard before blacking out was a flash of black and red hair in a big metal suit getting closer and a shout of  "Oh shit!" .

Then it all went black as I slipped into the world of unconsciousness.

AUTHORS NOTE-
I feel like this one was a little rushed but tbh I wrote this at like 1:30 AM and I haven't slept in days because the meaning of sleep eludes me!
Anyways the next chapter will be Marks POV and I m excited for that !

Anyways I hope I'm doing ok on my first X reader (I read them I just don't write them) and I promise that the next chapter won't be as rushed!
