In the depths of the Atlantic Ocean there resides a special underwater race known as mermaids, well mermen if you were male. Like the abundant life of the seas, mermaids come in various shapes, forms, sizes, and of course species. At the very top of the food chain are the vicious predators known as mersharks, with the magical ability to control their shark brethren and have the strength of ten sharks. These carnivores feast upon smaller prey such as fish, squids, or other sea creatures unfortunate enough to come within their reach, though mersharks do have a tendency to dine on other species of mermaid. With these heraclean creatures of the seas are the intelligent merdolphins. Like their hunting rivals the mersharks, merdolphins fancy the taste of many sea creatures, but rarely, nearly slim to none, dine on other mermaids. Both species are at war because the seas cannot sustain both species hunger. The other species of mermaid have been quite cautious of the sea depth they travel as well as the time of day if they do not desire to be caught in the mafia violence or meeting the rows of mershark fangs that wait in the shadows. The raging sea wars have all in hiding, all excluding an optimistic mermaid-lionfish named Kimberly Possible, Kim for short, who cannot stand being in hiding and decides to go out for a swim in the depths below her reef home.

"Uh, KP we really, really shouldn't be out here. What if we see a shark or worse a mershark?" a blond mersturgeon cringed at the thought of the underwater predators.

"Will you relax? We are not going to run into any sharks or mersharks. Don't you want to be able to explore the vast seas with freedom and not cower in fear because you think someone's going to eat you?" a young redhead asked, clearly enjoying the interesting sights of the deep sea level. "Hey look at that," she said as she pointed to a lionfish.

"Kim, you know you can't charm lionfish. You just don't have the magic for it, yet." the freckled merman said, peering over his friend's shoulder at the small fish.

"I'm getting it. I'll have you know, mom has been giving me some tips thank you very much." the offended mermaid scoffed. "Come on little guy. Do a, erm... do a backflip." Kim politely asked — a green glow flickered in her eyes.

The lionfish looked at the mermaid trying to charm it and decided to give her a raspberry. The small fish hitched its tailfin upward before it swam away.

The adolescent mermaid pouted. "Don't worry about it, I'll get it sooner or later." she sighed, her optimism returning to her face.

The blond smiled at his best friend. "That's the spirit Kim," he said as he gave her a thumbs up.

In the distance a rumbling sound caught the pair's attention, green flash illuminating the sea crater.

"What was that?" she asked.

"Don't know and quite frankly I don't want to know." he replied, clearly trying to attempt to flee, but was thwarted by his best friend's grip on his dorsal fin.

"Oh, don't be such a guppy and come on." the redhead groaned as she swam to the glow.

The young mers peered over a rock incline, a scene of a green female mershark surrounded by a pod of merdolphins.

"Back the fuck off!" she snarled, the water bubbling around her clawed hands.

"Oh please, Lady Shego. There is ten of us and only one of you. If we take you to our leader your uncle will give up the mershark hunting grounds to the Dolfinz!" the assumed leader of the group cackled with a high voice.

"Huh, and here I thought merdolphins were supposed to be smart. You must be stupid to intentionally misspell your species classification for a mafia name and you must be stupid as whale shit if you think that you can take me." Shego snarled – the bubbles soon replaced with what looks like green sea lava.

"Okay KP. We came, we saw, let's get the heck up out of here!" the merman, pulling his friend by the arm.

"Ron, even a mershark doesn't deserve to be jumped by merdolphins. We have to do something," Kim said, trying to swim to the outnumbered mermaid until her best friend grabbed her by the tail fin.

"Kim, no! This is where I draw the line in the sand! This isn't our war so let's leave before we have to explain to our parents why we're missing limbs," he pleaded.

"Ron I can't believe you," the redhead scolded.

He flinched at those words.

The mershark lashed out at the pod of merdolphins with her razor sharp fangs and lava flowing claws, tipping the fight in her favor.

The merdolphins numbers dwindled down to three. One of which jumped her while she was distracted with his mafia family; he threw a sharpened starfish coated with the venom of a box jellyfish, piercing her thick shark hide and leaving a gash.

The feeling of electrical needles surged her systems, causing her to double over in pain.

"See she's going to die," Kim said as she pointed at the injury.

"Okay, okay, but I am so gone after we help." Ron said.

"Okay this is what we'll do." she said before leaning in to whisper her plan in the mersturgeon's earfin.

Ron looked over the rocks and gave Kim the signal before he went for cover.

Kim took a deep breath before she hit a high C note.

The landscape slowly shifted out of place, which caused the rocks in the surrounding area to slide down the sea wall of the fighting area.

"Oh Ægir!" the remaining dolphins said, trying to flee in hysteria. Two merdolphins were crushed by the rocks while one managed to escape.

Clouds of sand surrounded the former battlefield.

The small mermaid-lionfish looked downward to see the female mershark literally licking her wounds.

"Damn merdolphins! Fucking venom!" she hissed, trying sucking the venom out of her system.

Kim swam a little closer, but remained hidden.

Being a mershark gave Shego the ability to read electrical pulses like her shark brethren. Her glare pierced through the sand clouds in the general direction of where Kim was. "Who's there? Come out coward so I can eat your face off!" she growled with her rows of fangs bore.

The smaller mermaid revealed her face before slowly swimming to the fallen mershark. "Are you okay?" she asks, her eyes shifted to the wound before snapping back to the eyes of the sea predator.

Shego chuckled. "What do you think? I just got jumped by freaking merdolphins so I don't think I'm doing too hot." she replied irritably, she chocked up a bit of blood. "They got me better than I thought." her internal voice echoed with a hint of worry.

"You're bleeding... a lot," Kim stated, slowly nearing the downed mershark.

"Pfft, thank you captain obvious." Shego huffed. Her eyes glanced at the smaller maiden's for a brief moment. "Nothing you can do about it anyways." she sighed as she watched her oozing wound bleed out into the ocean – her vision beginning to blur.

"Actually I can." the redheaded teen said, a tear formed into her left eye. The tears migrated until it spread over the wound.

A sensation hit the wound. It was cool yet warm at the same time.

Shego didn't feel the pain and her wound was closing, but the blood lost had her disoriented.

"What the hell are you?" she muttered.

"Just a mermaid-lionfish." Kim admitted, stroking a stray hair from Shego's face. "You should be happy you can roam around freely thinking no one can eat you." she half-joked.

"What do you mean? It's a free ocean." the shark woman scoffed, slowly started to drift into slumber. The lionfish's touch was comforting and gentle.

"Mersharks practically eat anything they can catch which is everything. Where I'm from we have a curfew and to be honest I'm not supposed to be this deep in the sea. My parents would freak if they knew I was here and actually talking to a mershark," the younger mermaid admitted.

"Not all of us are as big and bad as other mers say we are. I wouldn't eat you. I like to play with my food, but I wouldn't eat someone who saved my hide. I like you." Shego yawned.

"Thanks, but I still like the lifestyle you live, so carefree. Must be wonderful," the adolescent mermaid whispered with a pout.

"No pouting." the carnivore said, placing her clawed hand on Kim's. She smiled which caused her companion to smile in turn.

Kim said something, but Shego could barely make out the sounds that came afterwards.

A voice that sounded better than any angelfish choir could rung in the mershark's earfins clearly.

What would I give
To live where you are?
What would I pay
To stay here beside you?
What would I do to see you
Smiling at me?

Where would we swim?
Where would we sway?
If we could bask all our days away?
Just you and me
And I could be

Part of your world

A warm hand graced the mafia shark's face.

I don't know when,
I don't know how,
But I know something's starting right now.
Watch and you'll see
Some day I'll be

Part of your world

Shego held the hand in a warm manner, but the hand retreated at the sound of shouting.

"Shego! Shego!" the voices of her brothers called out.

Kim swiftly swam away before the other mersharks wouldn't be kind enough not to eat her.

"Dear Triton, we came as fast as we could when we smelled the amount of your blood miles away. We thought something happened to you?" a purple lanky mershark said.

The green mershark's vision came to focus; she slowly sat up to address her brothers. "I'm fi-," the pale shark woman said before taking a pause. "... Wait, where'd she go?" she asked as she looked around.

"Where'd who go?" a bulky blue haired mershark asked, his eyes looking for any sign of movement.

"I guess it's nothing now. Bet she swam for it because of you guys anyway." Shego sighed, the latter she muttered.

The Go brothers looked at their sister quizzically.

"Well you're okay and that's good. Now let's head home. Aunt Laura said we're having anglerfish and clams," the Wegos said as they rubbed their bellies.

The ebony haired mershark swam away with her brothers humming the melody the mermaid sang to her, which was the most soothing sound she's ever heard.

Kim peered over the rock she hid behind and decided to find her best friend.

"You sang to her?" Ron asked befuddled, shaking his head in disappointment.

"Yes, she's a very nice mershark. I got to meet her again." she said, her eyes barely making out the visible outlines of the shiver of mersharks.

"Uh-huh. No! You're parents will go berserk on your tailfin and mine because I didn't try to stop you." he said as he pulled his friend back to the reefs.
