A high-pitched snarl echoed the confines of the warm tropics of the Atlantic waters; a bulk merdolphin had his hands around one of his employees' throat.

"Now let me get this straight, not only did you not get Lady Shego, but a mere mermaid-lionfish killed my mermen?" the large merman shouted, throwing his incompetent lackey to the side.

"Forgive me my Lord, but we weren't aware we were being spied on. I didn't even know she was there until I picked up on her voice by sonar before the rockslide. It was terrible sir. All of our men were crushed by a runt!" the slim merman spat, clear despise of his failure in the task his leader assigned him.

"Impossible! I want no more fuck ups, you got that?" the merdolphin mafia lord sneered, his jagged teeth clenched.

"Sir, yes sir." the younger merdolphin saluted.

In the murky depths of the mershark caverns – the Coves – a mersquid slowly came into the light, followed by a pair of ominous glowing emerald eyes. "Madam Shego?" the merman asked, eying his client suspiciously.

"Aston?" Shego replied, giving a glare that indicated that she was in no mood to play games.

They both gave a nod of confirmation.

The mershark's eyes gazed over the area to validate that they were alone. Her eyes shifted back to her informant. "So tell me Aston, what do you have for me on that redheaded maiden? I'd do this myself, but you already know why," she stated, carrying herself with the airs expected of a mafia princess.

Aston cleared his throat before addressing the mafia royal respectively; he truly didn't wish the wrath of the Go mafia on his species. "Madam, when it comes to information, I can get my tentacles on more intel than you can count. The mer's name is Kimberly Anne Possible, Kim for short. Current residence: Central Reefs and a student at Central Reef High School. Since it's still morning and a weekday the girl will most likely be there," he reported, head bowing lowly.

Shego smirked with satisfaction as she loomed over the squid. "Good job and here's payment," she said holding out an empty hand.

"A thousand pardons Lady Shego, but I don't get it..." the merman stated befuddled.

"It's quite simple my good merman. In exchange for giving me the information I seek, I let you leave the Coves with all of your limbs and I don't eat your kin. Now beat it before I change my mind!" the shark woman snarled, rows of refined fangs bare.

The sight of her substantial fangs was enough to make Aston flee for his life.

The green maid snickered. "Sucker. Now let's pay a visit to my little Angelfish in the reefs," she grinned, swaying in a predatory way as she neared the school.

In the halls of Central Reef High School, a certain mermaid was not in her usual chipper mood.

Kim closed her coral locker with a pout adorning her face.

Monique, a mermaid-blackfish stared at her best friend disapprovingly. "Girl you're as crazy as a sea witch if you're thinking of seeing that mershark again! They eat us for fun remember?" the sea-maiden scolded.

"But she fascinates me. I can't help it." the redhead sighed dreamily.

"She's got it bad!" the ebony mer whispered to her other best friend.

"Uh-huh." Ron replied.

Just as the group was turning to head to class early, a roar of screams permeated the halls of C.R High.

"Somebody call Reef Patrol!" a distressed merman cried.

"Mershark!" a school of teens panicked.

The sound of a mermaid-eating predator swimming the halls of the school filled Kim with fear. She fled from the potential danger, but an eerie feeling that someone was on her tailfin surged from her spine to her dorsal fin. The young lionfish peered behind her to see if she was still being pursued.

The silhouette of the carnivore grew as it neared the teen slowly.

Kim crossed her arms in hope of guarding her face. "Please don't eat me. I can promise that I don't taste good," she pleaded, eyes closed, not yearning to witness her own demise.

"Ægir, Kimmie didn't I tell you I wasn't going to eat you the first time?" a familiar voice teased.

"Shego!" the younger squeaked, smiling as she swam around the mershark. "Wait a minute. What are you doing here? Someone will call Reef Patrol," she warned.

The taller mermaid cast a glance downward at her amusing Angelfish, a fanged grin etched on her face. "Isn't it obvious? I came to see you, doy! Pfft, I'd like to see those insignificant whelps you call, 'Reef Patrol' try to stop me. It gives me the opportunity to be a good older sister and give my twin brothers some nice bones to add to their collection," she scoffed half joking, only half.

Kim gulped, too petrified to move.

"Kidding, sort of..." Shego apologized, rubbing the back of her neck nervously. Finding a way to connect with one so different from her species proved very difficult for the mafia mermaid; by Davy Jones' watery Hell mermaid-lionfish were a divine delicacy to her people.

A tanned mercarp crossed their path in attempt to find a place to hide. A gasp escaped her throat. "Kim, are you insane? That's a freaking mershark! She'll rip you open and play with your guts before she slowly eats you! Swim for your life!" Bonnie yelled. She may not like the redhead, but she never wanted her dead.

"Hm, not a bad idea for lunch..." the pale maiden pondered aloud.

"Shego!" Kim scolded, pinching the shark's thick hide.

Shego's eyes caught Kim's sudden movements, she barely realized she was being reprimanded until she looked at the mer. "What was that for?" she feigned agony, internally smirking at what she claimed was hers.

"No eating anybody." she said disapprovingly.

The green shark thought of her current situation, she definitely didn't want Kim angry at her, but she was a feared huntress of the sea after all. "Aw, but what if I get hungry? Maybe a little nibble? Most of them will be left. I won't eat them all I swear." the brunette promised, a smile adorning her face as if she deemed herself a saint for her actions.

Bonnie gaped at the sight of Kim, a mermaid-lionfish scolding a not only a mershark, but the mershark mafia's princess. "This is too good to be true," she muttered, swimming away from the scene.

"Please just leave. No doubt I'll get into trouble for this." the smaller pleaded.

"Fine, fine." Shego said, towering over the smaller mermaid. She bent over and nipped at Kim's shoulder, leaving small dots of blood where her rows of fangs were.

Kim shirked back. "What happened to not eating me?" she shrieked, defensively covered the minor wound.

"Relax, it's just a love-bite. It's how you say hello and goodbye in shark, as well as a few other things," the predator said with a wink before leaving the school.

The lionfish stared confused at the weird mershark, but brushed off the awkward behavior. She briskly swam around the corner of the halls to hear faint whispering. The redhead found her two best friends gaping at her in hope for an answer. "What?" she asked, returning the same awkward stare.

"She bit you." Monique said, eying the small wound.

"She said it's how sharks say bye and for some other things she failed to mention." Kim said, muttering the latter.

"We get that, but rumor is spreading faster than krill while a whale's hunting about you being tight with the Go mafia!" Ron said.

"What?"

"Hey Kim, sit with us at lunch." Alex said, hooking an arm through Kim's.

"No, sit with us. We have so much to talk about." Marcella said, hooking Kim's other arm.

"Whoa people! Kim ain't sitting with none of you bottom feeders, now get!" Monique shooed off.

The school of merpeople soon dispersed mumbling.

"That's right! Go on you moochers! If anyone's getting Go mafia connection protection it's us." Ron said, thumbing himself followed by Monique.

"Ron!" the mermaids snipped.

"Just a joke, mostly." he admitted.

The mermaids rolled their eyes at their blonde friend.

The bell rang for the signal of the last period of the day. The trio hurried to their Marine Biology class; Mr. Barkin was subbing for Mrs. Trout.

"Listen of merpeople! Today's lesson is on mershark anatomy. Turn your books to page 176." Mr. Barkin ordered.

"Why does it have to be mersharks of all species?" Kim groaned. To her dismay the class went by rather slowly. At the sound of the bell the mermaid was the first to exit the classroom. The next class was one of her least favorite classes considering that her magic abilities were below average. "Mermaid magic, yay..." she sighed, taking her seat.

A pudgy brunette began to write on the board for her students before addressing her class. "Okay class, we will be finishing our projects from yesterday. The last three people to finish are Ronald Stoppable, Felix Renton, and Kim Possible. Let's finish in alphabetical order. Ms. Possible, please tell me you've improved since last class?" the woman asked.

"Maybe..." Kim muttered, shirking at the humiliation amongst her peers.

Surprisingly, Bonnie refused to taunt her in front of the class as usual.

"Here goes nothing," she murmured, an enchanting melody echoed the halls, but to no avail a single lionfish appear. "Of course." the mermaid groaned, taking her seat.

After Ron and Felix enchanted their species for the class, the principle of Central Reef spoke through the intercom. "Attention students, we have a bit of an emergency. We are on lockdown until further notice. A shiver of sharks is currently circling the school walls. Have a nice day," he informed, ending transmission.

The class let out a groan.

After the sharks dispersed, the school was released to head home.

As Kim swam home, she receives a few glances from her schoolmates who took the same path. The olive eye mermaid her entered her reef. "Finally," she sighed in relief.

"Kimberly Anne Possible! Get your tailfin in this kitchen hollow now!" her parents ordered.

"Oh boy."

"Why is it we received a message from your school about a mershark atta-" James said before taking notice to the bite. "Dear Poseidon it bit you. It wanted to eat my guppy," he sobbed.

"James get a hold of yourself." Anne groaned, pinching her nose bridge.

"I don't see what the big is. We're uh, close and she was just saying goodbye." Kim said, covering the bite.

Her mother didn't know what to think of the situation. "I don't buy that! Mersharks don't like other mermaids, unless they want to have them on a plate." she stated.

"Then why am I still alive? If she wanted me dead, she would have done it by now." the younger mermaid-lionfish said.

"You're hurt because of her! If you're so close I want you to bring her here so we can have a serious talk." Anne ordered.

"How am I going to do that?" the smaller redhead asked.

"You said you're close so find a way." the older mermaid said before leaving to prepare dinner for her family, she clearly wanted to drop the discussion.

"Fine!" Kim huffed; she turned to leave her home. "How am I going to find a mershark? Put a glow worm sign over my head that says 'LIVE BAIT'." she pouted. A thought occurred. "Shego, Shego." the mermaid whispered, roaming the ruins of the place they first met.

A shadowy figure skulked behind the unsuspecting teen. "Yes Kimmie," Shego whispered in Kim's ear.

"Gah! Don't… do that!" Kim said with emphasis, the spikes equipping her spine sticking out.

The mershark swiftly backed away. "Sorry. Last thing I need is getting poisoned again." she sighed in relief.

The lionfish lowered her spine. "Last resort defense mechanism. I don't like using it if I can help it," she admitted with a blush.

"So, what's up? You must want something if you're looking for me Kimmie or did you want to see me just because." Shego said huskily while circling Kim. Her tailfin brushing Kim's chin seductively.

Kim gulped, her blush matching her crimson hair. "The funniest thing happened actually," she sheepishly smiled.

"I'm listening. Humor me." the mafia shark grinned.

At the Possible family's reef, a green mermaid began to growl.

"I am not amused." Shego scowled as she entered the reef.

"Well I didn't say it was ha-ha funny." Kim reminded.

"You'd suck at being funny if you were a mer-clownfish." the older stated, still scowling.

"Hicka bicka boo?" Tim said.

"Hooshaw!" Jim said, giving his twin a high-five.

"Wait, 'til everyone at school hears a mershark has been to our reef." Tim said.

"Badical!" Jim replied.

The predator snapped her row of fangs, growling at the pests.

"We'll just help mom in the kitchen," they concluded before fleeing.

The mafia royalty had a smirk on her face until her hostess gave her another pinch. "Okay, okay. No eating 'em, yet." she surrendered.

Anne sported a scowl of her own, she couldn't believe that a mershark was lurking her home. "Food is ready girls." the older mermaid called from the kitchen.

Shego's eyes began dilating before slowly returning to normal. "Food sounds good." the predator said, a hint of drool sliding down her lips.

Kim led the way to the kitchen.

The carnivorous mermaid sat next to her hostess, she was receiving awkward stares from Kim's family. "What's a matter? Never seen a mershark before," she teased, her mafia upbringing coming to surface.

"Uh, never seen one so close without it wanting to eat you." James admitted.

"I won't eat Kimmie's folk, uh, just don't bleed or something." Shego requested with a fanged grin.

"Whoa! I bet she could rip through a steel chain with those things." Tim said, eying the rows of teeth.

"Cool!" Jim replied with excitement.

"Try being able to rip the steel from a ship's hull and sink it."

Shego accurately informed.

Anne's eyes bulged. "Okay, who's hungry?" she croaked, placing the plates on the table.

"What the fu-... I mean what is 'that'?" the brunette asked, prodding the greenery on her plate before sniffing the undersea vegetation.

"Kelp salad with barnacle topping?" Kim said, smacking her self on the forehead in realization. "Oops, sorry." the cheerleader apologized to the unsatisfied shark.

"It's... uh, cool... Folks never would give us vegetarian food. Who knows? Maybe mersharks can add something to their diet." Shego said rather optimistically for her taste. She put a coral fork through the salad, gazed at the greenery nervously and bit around the tips. Her eyes bugged out. She spit the kelp out and raked her tongue with the fork. "Yuck! Ew, ew, EWWW! How the heck can anybody live on this?" she asked, trying to rid the taste of the horrid vegetation. The huntress pushed the plate away with her index finger. "Never again. Ever!" she mentally noted.

"Sorry. You didn't have to try it to not be rude." Anne apologized. "I thought Kim was kidding about the mershark thing to hide the bite mark so I didn't prepare a carnivore's diet for you." the older redhead admitted.

"It's fine, I prefer picking what I eat anyways and there is a good selection on the reefs." Shego said, nibbling on her fingers in desire.

Everyone shirked at the statement.

Kim's mouth opened and closed, but no words came out.

Shego's peripheral caught her reaction, causing the woman to frown. "The fish Kimmie. Mersharks don't really head to the reefs that much meaning the fish are like a delicacy to my people." the carnivore scowled.

"I knew that... I just wanted you to tell everyone else that so they wouldn't worry... and it worked, so uh, ha, ha." the teen lied nervously.

"Did your parents ever tell you that you suck at lying?" the shark teased, which earned a slight blush from the younger mer.

Anne observed the pair interacting with one another. "Oh they're that kind of close," she thought, a chuckle escaping from her.

The two in speaking glanced at Anne confused. "What?" they said in unison.

"Oh, nothing. This is cute." the older admitted.

"I'm not cute, I'm deadly!" Shego huffed, folding her arms across her chest, a roar escaped from her.

"You didn't have to roar to make a point." Jim said as he finished his dinner.

"Yeah." Tim agreed.

"That wasn't me, well it wasn't from my throat," she admitted, emphasizing her point with a hand over her stomach.

"You should get something to eat. My parents know we're cool so you can leave to eat if you want." Kim said half disappointed.

"Not just yet. Call it shark instinct, but I feel daddy doesn't trust you with a mershark just yet." the older quipped, a wink cast towards the merbass.

"I, er, how'd you..." James said.

"Sharks are sensitive to electrical impulses, it's called electroreception; and your body's pulses are raging at the thought of your daughter being with in leagues of me." Shego said with a smirk, though she was highly pissed internally.

"Alright, I'll admit it. It's too dangerous and I won't allow it until I'm convinced otherwise." James said firmly.

"Such a fuddy-duddy. I got the perfect plan for someone like you." she thought with mirth. "I can assure you that Kimmie will be safe with me. No mermaid will bring any harm to her for starters. If you were some random idiot in the sea, would you mess with a girl who has a mershark mafia member joint at her hip? I can even have a few of my uncle's hench-sharks to guard her if you're that paranoid? Oh and here's the bonus, no mermen will lay a finger on her." Shego grinned. "3,2,1..." she thought.

"I like the way she thinks! You are quite a suitable mermaid missy." James said with a grin.

"Thank you Mr. Possible." Shego said with false joy. "Hook, line, and sinker." she internally grinned. The shark-woman sat up and turned to leave. "Well since that's taken care of then I'll be taking my leave. Bye everyone." she said as she swam for the door.

A young mermaid-lionfish pouted as her guest left.

"Bubblebutt just go with her already." Anne leaned in to whisper.

"Huh? But what about -" Kim said before her mother put a finger to her mouth and winked. "I think I'll just go out for a swim," she said, heading for the door.

"Odd time to go for a swim." the merman said with a confused expression.

"It's okay dear." Anne assured. "Young love." she thought, eying her own mate.

"Hey Shego wait up." Kim called at the swiftly swimming mershark.

"Angelfish? What are you doing following me?" Shego asked.

"I wanted to go with," the teen said.

The mershark immediately scowled at the idea. "No way, nu-huh! You are not going hunting with me! No way in the depths of..." the mafia monarch exasperated until she looked at the weird expression on the smaller mer's face. "What are you doing to your face?" she asked, her gut wretched.

"It's called the guppy-fish pout. Pwetty pwease with sea salt on top?" Kim pleaded; her eyes seemed to get bigger and tears forming at the corners.

"Okay, you win! I quit! Just stop!" Shego said, shrouding her eyes.

Kim punched the open sea. "Yay." she squeaked.

"Just stay as far away as possible, okay? I don't want you getting hurt," the carnivorous mermaid asked.

Kim nodded in confirmation.

Beyond the reefs, in the open waters swam a large tuna fish. He happily swam about, enjoying his day until a shadow swam swiftly in his peripheral. He quickly turned his head and saw nothing. "Must be my imagination. Mersharks don't come up here." the tuna sighed in relief.

The shadow swam below the tuna fish, well out of its sight. Glowing malachite eyes focused on the unsuspecting prey, slowly dilating until they were pitch black. With the eyes rolling to the back of the shadow's head the figure struck with precision and clamped it's mighty jaws into the helpless fish. The figure went into a frenzy when the blood seeped out of her prey and into her naris. "Mmm... smells delightful." she whispered, lashing about with the fish in her jaws about until it tore into bits. The predator didn't make the effort to try and chew her food either.

"Shego can you chew your food, sheesh. That's disgusting," Kim yelled many yards away, slowly uncovering her eyes. She swore Ron had better table manners than the lovely she-shark in front of her.

The mershark unrolled her eyes. She looked up with dark eyes and blood slowly drifting off of her face. The huntress shook her head a bit causing her eyes to return to normal. "Sorry, didn't catch that." Shego replied as another chunk slithered down her throat.

Kim swam a few feet closer, unaware if it was safe to approach. "I said learn to chew. It's bad for your digestion," she repeated.

Shego rolled her slitted emerald eyes and made an attempt of chewing just to satisfy her hunting company, but her jaws made it slightly difficult. She growled and just threw the remaining carcass in her mouth and swallowed. "By Poseidon's might, you're divine, but you must be failing Marine Biology. Most merpeople know sharks can't really chew well." she mentally sighed, waiting a few minutes before returning to the redhead.

Kim frowned a bit. "That was Ted. I liked Ted," she sighed, eying the green mermaid's stomach.

"Sorry, but Ted was tasty." the mershark teased. "Head home Kimmie before your folks think I ate you." the mermaid said, swimming a few yards before coming to a stop. A thought occurred. "Can you answer something for me?" she asked, half turned to address the teen.

"Uh, okay. What is it?" Kim asked.

"Yesterday, did you sing to me before I blacked out for a few minutes?" Shego asked, waiting a response.

A silence drew out.

"Kim..." she said, turning to look at the girl.

Kim's eyes shifted to any direction except Shego's, but felt the predator's eyes on her. "...Yes" she mumbled, her eyes drifting back to the older mermaid.

Sharp shark hearing caught the muttered. "I liked it. Why were you stalling?" she asked.

"I thought you didn't like it. I'm magically inept, I can't charm lionfish so I thought I sounded revolting to you." the redhead admitted.

Shego gaped at Kim. "You, bad? You sound better than a choir full of mer-angelfish." the green woman complemented.

Kim blushed. "You don't mean that," she whispered, her eyes playing coy away from Shego's.

"Yes I do! It's down right enchanting." the mershark said breathy. "Will you sing that song to me again? You don't even have to sing the whole song." she asked, a hint of embarrassment on her face.

A silence drawled out.

"That was stupid of me to ask. You don't have to if you don-" Shego said, her ears picking up on a familiar melody.

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?

That was the voice, Shego's earfins snapped to attention at the enchanting singing. The voice was a canorous symphony for her alone to hear. It was sweet and soothing as seaweed, rich and vibrant, classy and enticing. It lured the she-shark closer until she was a few inches away from the lionfish songstress.

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 new phenomenon surged through the completely tame eyes of the mershark. She drifted towards her captivator until she pressed her body closer to the mermaid-lionfish. She felt a feverous euphoria that even her lava powers couldn't best. Her clawed hands cupped Kim's cheeks with smoldering eyes and Kim in turn cupped Shego's cheeks with the same affection.

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 pulled Kim into her embrace and bit at the bottom of the girl's peach lips in the most placid manner. Kim flinched the gentle sensation. It didn't hurt her in the slightest; it was as soft as the sea floor and as secure as anemone protecting a clownfish. The bite soon drifted to a full kiss. Shego pulled Kim in closer by the arch in her back, which made the redhead let out an elated cry. Just as the kiss sprout forth it soon withered, but the feeling after still lingered.

"She-" Kim whispered before a clawed finger pressed against her soft lips.

"I have to go now Kimmie, my folks will worry. I promise to see you tomorrow Angelfish." Shego whispered in return, a smile gracing her face before she swam away.

"Bu-" the half delirious mermaid replied before the mershark was out of her sight. Her heart set aflutter.

Though they were apart, the two mermaids hummed the song that sparked their first intimate moment in unison.

Kim arrived in her home with a new sway in her fins, half aware of her surrounding and quite frankly she didn't care. She entered her room with a distant look in her eyes and a jubilant smile radiating her face.

"What got into her?" Tim asked.

Anne squeaked. "So cute. My little girl's first." she said, looking at her daughter go to her room.

The Possible mermen looked at the older mer-lionfish quizzically.

Shego arrived at her family's cavern a little later than Kim arrived at her reef home. She had a different swagger in her sway, humming the enchanting song of her mate.

Her brothers easily took notice of the joyous emotions thriving through her body; their sixth sense could detect miles away.

The Wegos brushed it off as Shego being full for once, but Mego and Hego noticed the faint hint of a smile. The eldest brothers used their electroreception on their sister.

"You don't think?" Mego asked, turning to his tigershark older brother, his sense picking up on her heartbeat.

"Couldn't be. Not our younger sister." Hego said, scratching his blue locks in bewilderment, his senses reading her body movement.

Tiburón, the shark mafia lord and the Go siblings uncle brushed past the distracted she-shark. He used his electroreception on his niece.

Her heart was racing more than usual and her pulses were raging through her whole body.

"What in Davy Jones' locker?" Tiburón muttered, his eyes went to his eldest nephews for answers, but got baffled shrugs. He decided not to question it now, but he would as soon as he settled into his comfy cavern home.
