A/N: So, I've got a new story! This story is loosely based on Aquariumstuck, but only features the Amporas (along with an OC) rather than the other trolls (bc Cronus is my precious lil angel even tho he's not liked by basically everyone else). So please welcome the prologue, hope you enjoy!

Also sorry for the totally generic title, trust me, it'll end up fitting in!

Prologue - Cronus

The sunlight danced across the waves delicately as Cronus' grey and purple tail splashed among them. He was on a mission to grab some lunch, and had a major craving for tuna, so he swam at breakneck speed through a giant school of tuna and snapped at one large and meaty one. He cleared a space at the bottom and sat gently on a rock and began to snack on his catch. Multiple tropical fish circled his abdomen and chased after each other out of playfulness. His little brother, Eridan, snuck out of a coral reef nearby and head butted Cronus in the stomach, causing him to spit out a chunk of the tuna, allowing the little guppy to tear at the half eaten piece, earning a quick glare and a sigh from Cronus. Cronus continued to snack on the tuna quietly, occasionally tossing a meat covered bone at Eridan so he wouldn't whine to his father later about how Cronus "doesn't share".

After sucking off the rest of the meat from the tailbone, Cronus dropped the tuna skeleton, with the fins remaining, on the seafloor, and allowed Eridan to scavenge the rest of it. Eridan peeled off the remaining fins (Cronus thinks the fins taste the worst; they have too much muscle and fibers) and placed them in his mouth. Cronus remembers being Eridan's age and being hungry all of the time; it's common for guppies as they're trying to fill their body with the essential nutrients so that their bones can grow and that he could develop a successful tail and a successful swim bladder. Cronus and his father, Dualscar, were always worried about Eridan as he was the weakest in the roe and wasn't that great of a swimmer. Dualscar tends to have a habit of feeding Eridan even the he isn't hungry; he doesn't want a child that can't swim well.

Cronus felt a cold shiver go down his spine as his dorsal fin lifted up in the air-that's his defense mechanism, it always lifts when there's impending danger. He turned around to notice three mermaids submerged in the water, their eyes as red as fire and their black scales as sharp as knives. They all looked like triplets, besides the one in the middle having brown hair, one on the left having pink hair and the one on the right having blue hair. Cronus growled as he grabbed Eridan and shoved him underneath his arm, pushing a small chirp out of Eridan. The mermaids began to sing, and Cronus forcefully covered Eridan's ears; Cronus recognized these mermaids, they were the Sirens, dangers of the deep and holders of the most powerful singing voices that can kill one if they were to listen to just a few seconds. They came for their next meal.

Cronus began to swim in the opposite direction, but he knew that these Sirens were no joke. He felt the currents moving behind him; they were chasing him. The Siren's favorite meals are troll mermen, and that happens to be what Cronus is. Their second favorite meal is guppies, which is what poor Eridan is.

He came up to a large rock, and was quickly corned by the three devilish Sirens. He ducked, covering Eridan from their gaping fangs. The siren with pink hair lunged at Cronus, scratching him in the arm with her long red talons, letting purple blood spill out. Cronus then smelled an unpleasant odor; he was right in the middle of a piranha hideout.

The piranhas spilled out of the seaweed that encircled his long tail and smiled gleefully, revealing multiple sharp and jagged fangs; he had two groups of hungry fish that really wanted him and Eridan on their menu. A large figure came up behind the Sirens, and the Sirens turned around-Cronus figured this was his time to escape. He hid behind the tall figure, and watched the Sirens. The large figure had a purple and grey tail like Cronus-it was Dualscar, there to protect his young. He grabbed his Ahabs Crosshairs and shot a blue laser right through the heart of the brown-haired siren. Dark red blood spilled out of her fangs as she collapsed to the ground and her sisters smiled like hyenas and worked to tear at her body, along with the group of piranhas. Dualscar turned the two away from the gruesome sight and covered their backs with his large fins that trailed down from his arms. Cronus felt at ease with Dualscar guiding him back home, he knew that nothing bad could happen to him with Dualscar around.

Cronus awoke peacefully that next morning, tucked underneath Dualscar's tail fin which wrapped him like a blanket; Dualscar remained asleep as if the sudden movement had never even happened. He grabbed a piece of seaweed and munched on it quietly, and then heard a slight bang. He turned to the direction of the sound, which was behind him, and noticed Eridan on top of one of the multiple rocks in the cave, rubbing his head. Cronus smiled as he picked up his small brother and held him in his hands, rubbing Eridan's head where it hurt. Eridan wouldn't admit it then and there, but he felt comfortable in Cronus's hands.

Dualscar rose from his sleep soon after and grabbed Eridan out of Cronus's hands, causing him to chirp unhappily; a surprised look crossed Dualscar's face as Cronus straightened in an 'I-told-you-so' sense. Dualscar grinned and placed Eridan back in Cronus's hands, causing him to fall asleep gently and blow small bubbles through his small oval shaped mouth.

A loud engine whirring sound then surprised the Amporas, and they rushed out of their cave to notice a large fishing boat parked above it. Dualscar glared as two rods with lures slowly lowered their way into the clear blue depths. Cronus heard a voice, "I heard this spot is rich for troll mermaids and mermen." Another voice, "Yeah, hah, maybe we'll catch a good one today and be able to feed our families for weeks!" Cronus understood the language and scoffed; he and Dualscar were the only ones able to understand human conversations, but he wasn't sure at the moment if his father was actually listening. The same voice from before that mentioned about eating mer-trolls stated quickly after, "Let me get that harpoon gun out, mer-trolls aren't easily fooled by rods and lures." Cronus' eyes widened as a large harpoon shot through the depths and nailed Dualscar right in the stomach, causing purple blood to stain the clear blue ocean. Purple slimy tears spilled out of the now awake Eridan's eyes, and he chirped as he noticed his father drifting in and out of consciousness. Cronus tried to cover the wound with his hands, but the blood was spilling out too quickly, and he had just eaten that last piece of seaweed; he kicked himself for doing that as he could've used it as a gauze.

A net then shot through the water and encapsulated Cronus and Eridan, and another net encased their wounded father. The net lifted out of the water and pulled them onto the metallic silver floor of the boat, as Cronus found it instantly difficult to breathe and felt his gills slowly drying out. He took a quick glance at Eridan as his vision started to fog up, and noticed Eridan was already unconscious, and a grungy looking fisherman with a long beard taking off the net and grabbing Eridan and placing him in a red bucket with paint splatters and a broken handle. The fisherman then walked over to Cronus with a shank knife and almost got to stabbing Cronus in the neck, but Cronus took his long tail and all of his strength and swept at his ankles, causing him to fall to the ground with a loud thud. Cronus's eyes then shut, and he was powerless to open them again.

Cronus's eyes were forcefully opened as he noticed a powerful beaming ray of light piercing his eye. He sunk away from the light and looked up to notice a female scientist and a coast guard. The female scientist was diligently taking down notes and the coast guard was looking worriedly at Cronus. Cronus met the gaze of the coast guard and he asked, "Are you alright?" Cronus chirped, and the coast guard stated, "At least he can try to communicate." The scientist looks at him with dismay, "He's a fish. He's not going to speak English, you know." Cronus rose gently, and the coast guard grabbed a spray bottle and spritzed his gills, causing Cronus to tingle with happiness; he realized how much he missed water.

The coast guard, along with some other men, grabbed Cronus: two men at his tail and the other two having a firm grip at his shoulders. They dropped Cronus in a large tank of water in a darkened room. Cronus examined his new surroundings: the tank was in a darkened room with three more empty tanks on the back wall. Blue lights shined on the floor, creating an ocean-like pattern. His tank was large with crystal blue water, complete with a small cave and a large rock in the center. Multiple varieties of sea kelp protruded from the floor and waved around like tiny dancers throughout the water. Cronus smiled with glee as he ripped a piece of the sea kelp and began to munch on it contently. He was just glad he was back in the water.

"It seems like he's fond of his new habitat," The scientist explained, and the coast guard smiled. Cronus noticed this and instantly felt an attraction to the coast guard like he'd never felt before...his eyes were as dark as the depths and his hair as black as the Siren's tails, complete with streaks of red. The coast guard walked up to the glass and placed his hand on it; Cronus cocked his head and placed his hand to match the outline of the coast guard's. The coast guard then began to blush as he looked away, and Cronus smushed his face on the glass, clearly trying to get attention from the coast guard. The coast guard gently turned his head and noticed this and doubled over laughing soon after, and Cronus smirked, keeping the kelp in his mouth like it were a rose in a male flamenco dancer's mouth.

The scientist walked away with her clipboard and the coast guard turned to Cronus and waved, to which Cronus blew a kiss towards the bashful coast guard. He giggled and walked out, leaving Cronus behind with his smitten emotions.

Eridan wriggled in the red bucket uncomfortably as he was carried into a small room containing multiple tanks of jellyfish. He was placed in a medium sized tank by himself (or so it seemed) and he swam around in circles, chirping to try and get either Cronus or Dualscar's attention. A chirp rang through the rest of the tank, and Eridan looked on in horror as a small blue mermaid emerged from a small batch of kelp in the back of the tank. He squealed in dismay as he tried to swim away, but his guppy fins wouldn't carry him that far as the mermaid caught up to him and grabbed him by his cape. She placed his tail in her mouth and threw him up in the air and caught him again, as Eridan began to feel nauseous.

The blue mermaid let him go and she chirped again, but remained still so Eridan could study her: she wasn't that old, probably just had gotten her new tail, and she had tan skin with blue scales on her sides and sharp darker blue scales on her bottom torso. Her long blonde hair cascaded down her shoulders, and her light yellow eyes were enticing to Eridan. He swooned as she picked him up again and started to pet him, and he chirped with happiness as she rubbed his small horns at the top of his head.

The mermaid chirped, and Eridan understood what she had said, "My name is Sereia. What's your name?" Eridan chirped back, "I'm Eridan, Eridan Ampora." Sereia smiled, "I like that name." Eridan sighed, "Me too." Sereia giggled at his comment, and smiled, revealing rows of sharp teeth. Eridan shrunk back, instantly being reminded of the Sirens, "You aren't related to the Sirens, are you?" She giggled, "No! I was a mer-troll guppy, but I had tropical mermaid genes, which is why I'm not gray and I don't have horns anymore. I used to have all that stuff but now I don't!"

Sereia continued, "I'm really happy I have someone to spend my time with now!" Eridan giggled, "Me too! We'll be best friends, right?" Sereia nodded, "Of course!"

Both fish latched pinkies, repeating a particular oath, "Never shall we part!"
