In the Anti-Skullgirl Lab, each lab has group of black-ops operatives. There have been many Last Hope squads in the past, but the latest team was a team of five operatives with this jewel nurse Aquamarine being the only one of them. Her team worked for the helpful Lab Four and performed duties into the advanced research. The most recent team was led by Morganite with Aquamarine serving 2nd in command and the other members are Maxixe, Helia, and Goshenite. They also helped their master Stanley developing high-tech weapons for the lab and each other in case of battle. But then, everything changes when Double and the Skullgirl joined forces to wipe out the Last Hope out, leaving Aquamarine being the only survivor left. She has short white hair flares out at the back, teal eyes, and tan skin. She wore a black sports bra, black short shorts with pink hearts at the thighs, and white high-heel boots with metal soles. On her back was a pair of black mechanical bat wings. Before she can meet her end at the hands of the Skullgirl, she was coerced into joining the Skullgirl as her elite minion relentlessly.
As she was force to join the Skullgirl's orders, Aquamarine recognize the Lab 0's experiment that Valentine created as the only hope to stop the Skullgirl.
'I guess I don't have any choice.' Aquamarine thought. 'It's up to her, now. Painwheel will need to finish this job for Valentine. I'm on my own now and I will avenge my friends.'
At the church, Aquamarine was confident to serve the Skullgirl but she wants Valentine's project to finish Marie herself. She keeps tabs on Double to make sure she doesn't find out her true intentions during her mission.
"Aquamarine, there are those that would interfere with my plan." Marie instructed. "Infiltrate Lab Eight and see to it they do not."
"Yes, Marie." Aquamarine said with a nod. "I'll leave at once."
Arriving in one of several Anti-Skullgirl Labs created to aid in the destruction of the Skullgirl, Aquamarine gazed around as she noticed the place was a home to a wealth of agents looking to end the Skullgirl's rampage through the Canopy Kingdom, many of them heavily modified with advanced technologies or parasites. It also has computer terminals, heavy machinery, and mad science that are mainstays within the confines of Lab 8's uninviting interior. Before she can do her job, Aquamarine was confronted by a young cartoon girl. She has short orange hair that was covered by a big top hat, black empty eyes that almost resembles one of those old cartoons, and razor sharp teeth. She wore a purple dress with a big red bow, two slender metallic arms with metallic eyes placed at intervals on each arm covered by white gloves, and brown shoes.
"Are you Project Peacock?" Aquamarine asked.
"Yeah, and you're one of those nurse whose back was mortally wounded by the incident that destroyed Lab 7." Peacock replied. "So what's that on your back?"
"Thanks to that incident, I went through an operation on her back." Aquamarine explained. "One of the scientists gave me these bat wings that gave me extreme speed and strength. After that, I've developed many jewel-related ninja weapons for occasions."
"Since I was built to defeat the Skullgirl and it looks like you're working with her, I have to defeat you first." Peacock said firmly.
"Alright, give me everything you got." Aquamarine said sternly.
"Hellooooo, nurse!" Peacock swooned playfully.
"You're the best Avian's got? Let's put that for the test!" Aquamarine said with a grin.
Aquamarine jumped up in the air to avoid Peacock pulling out a gun that suddenly made a knife come out of it and delivered a combo of rapid and powerful kicks to attack the Lab 8's creation. Peacock fired several big bullets from her revolver towards Aquamarine, causing the bat nurse to dodge all of it. Aquamarine then fired a hail of gem missiles at Peacock from her wings before delivering a flurry of rapid powerful kicks. Peacock then planted an enormous Lenny bomb on the floor next to Aquamarine and then pulled out her revolver to fire one shot at the bomb that caused it to explode, sending Aquamarine in the air for Peacock's chance to fire a continuous laser beam from her hat and then fire several individual laser bolts from her Eyes of Argus. But Aquamarine wasn't through yet. Aquamarine quickly jumped in the air as her wings spiral down her legs forming a drill at her feet straight at Peacock that led to her opponent's defeat.
"You're despicable..." Peacock said, falling down on the ground in defeat.
"Guess you're not so strong after all." Aquamarine smirked.
Arriving in one of the Canopy Kingdom's most illustrious cities, Aquamarine observed the Canopy Kingdom's most illustrious cities and knew as the city of art, culture, and sophistication that played the host to a diverse population of humans and ferals from all corners of the bustling streets that resides many strange and mysterious fighters. But she spotted a group of Black Egrets troops, where their leader was observing her. She has long red hair with bang on her right side and dark orange eyes. She wore a black blouse with a metal upside-down christ cross on her chest and long sleeves, black mini skirt, and black flat shoes.
"You!" Parasoul called. "Are you one of the Anti-Skullgirl Lab's nurses?"
"Yeah, and I see that you are the princess of the Black Egrets." Aquamarine answered. "But now I'm doing my duty for the Skullgirl."
"Then, you are a traitor to the labs." Parasoul said firmly. "Stand down and surrender."
"Not gonna happen." Aquamarine sneered. "I don't do the surrender."
"I'll show you how we deal with sly nurses." Parasoul said sternly.
"I don't take orders from you anymore." Aquamarine scoffed.
Aquamarine charged forward and jumped into the air while kicking in front of Parasoul with both legs in a rapid manner that gave the princess painful damage. Parasoul began her first move as she jumped on her umbrella and releases several flaming stabs beneath her to attack Aquamarine. Aquamarine quickly got back up on her feet and flew up in front of the princess and threw out a handful of sharp counterfeit colorful bomb gems at Parasoul from afar. But Parasoul wasn't done yet as she swiftly thrusts her umbrella four times very quickly while delivering a vertical slash to attack more. After a few minutes of quick thinking and strategic dodges, Parasoul started to become weak that gave Aquamarine opened her arms sidewards as her wings sprout multiple arrow-headed attacks that spear the princess, allowing her to defeat Parasoul simply when the bat nurse delivered a powerful kick.
"Lousy...traitor..." Parasoul said, falling down on the ground in defeat.
"Your troops will never follow you...once they've seen my bats." Aquamarine smiled.
Arriving in a nighttime seaside Dagonian-populated section of New Meridian, Aquamarine was quickly observing around the town of Little Innsmouth. But she gasped sharply as she saw a familiar girl that looked like she was cruelly experimented on. She has a boney body with veins showing out and sharp, painful nails in her shoulders. Several spikes were coming out of her arms and fingernails with a big bladed pinwheel on her back and had on a brown mask that had attached on her face.
"Painwheel? Is that you?" Aquamarine gasped surprisingly.
"AQUAMARINE!" Painwheel snarled. "Don't stand in my way! She'll pay for what she did to me!"
"But somehow you are resisting Brain Drain's control." Aquamarine calculated. "Impressive. You have to be incredibly strong to overcome his influence." She let out a soft grin. "Show me if you're stronger to handle yourself!"
"Uuuurrrghhhh..." Painwheel growled.
"Let's see if you learned anything what Valentine have taught you." Aquamarine said with a grin.
Aquamarine tackled Painwheel with a strong swift kick, sending her crashing to the ground. As Painwheel got up, she ran towards Aquamarine with her blades extended towards the bat nurse before she leaned towards Aquamarine and spins the Buer Drive multiple times. Aquamarine launched herself forward and delivered a combo of rapid and powerful kicks at Painwheel. But Painwheel launched Aquamarine in the air and unleashed needles all on the bat nurse's body that causes her to scream painfully and then she drove her blade wheel on Aquamarine sawing into her before she can throw her into the ground. As Aquamarine got back on her feet, she took the steel claw that belonged to her closest friend Maxixe and rapidly stabbed Painwheel with alternating claws multiple times that encloses her to major damage. Painwheel punched Aquamarine to send out multiple nails on her upper arms for delivering the ninja massive damage. As the girls continue to battle brutally, Painwheel was growing tired every second. Aquamarine then defeated Painwheel by jumping in the air and pointed both of her legs downward like a spiraling drill to dive directly downward from the Lab 0's creation's position.
"No..." Painwheel said, falling down on the ground in defeat.
"I'm feeling sad for you." Aquamarine said softly.
Aquamarine walked over to help and comfort Painwheel, but the Lab 0's creation brushed it off and got up on her own.
"No!" Painwheel cried. "I can't lose! I must destroy Valentine!"
"What about her?" Aquamarine questioned. "I thought your true purpose is to defeat the Skullgirl."
"My true purpose is to destroy Valentine!" Painwheel screamed.
"You are persistent, I'll give you that." Aquamarine admitted with a smirk. "You just need more time on your strength. But if you insist on getting revenge, visit Valentine at the Grand Cathedral if you want to fight her."
"I will kill her." Painwheel sneered.
"Hmph, I'm looking forward to that." Aquamarine grinned.
Arriving in a towering skyscraper that pierces New Meridian's skyline, Aquamarine sneakily walked in the tower and observed the place in awe. The tower is a massive complex that has a spacious elevator to ascend upwards in the boss's office. Aquamarine stepped into the elevator and gazed at the bright neon lights of New Meridian shining in through the windows during her lengthy ride. But she realized that she's not alone. She turned around to meet the biggest sensation in the Cirque des Cartes. She has cerulean hair that is tied in a sharp ponytail, beautiful and simple black eyes, and wore a sleeved orange and black mini dress and a pair of black thigh-lengthed boots with small skulls.
"What are you doing here?" Cerebella asked sternly. "Do you have an appointment with Vitale?"
"That's none of your damn business, sweetie." Aquamarine said with a sly smile. "Although your bosses are next in my killing list."
"Then, you have to get pass me if you want him." Cerebella snapped.
"Gladly." Aquamarine smirked. "I'm fully ready to analyze your skills and your living hat."
"Time for your curtain call." Cerebella smiled.
"Your hat is connected to your head...for now." Aquamarine said cunningly.
Aquamarine charged forward to attack first with a strong kick, but Cerebella hit her in the air and then jumped up to spin her hat in a helicopter motion. Aquamarine jumped back onto her feet and fires a hail of missiles at the circus girl from her bat wings. Then, Cerebella used her hat to send a hard knuckle punch on Aquamarine's stomach. Aquamarine swiftly raised her left hand above her head and forms a series of black ripple-like waves at the position where Cerebella was standing to damage and disorientate her. Cerebella hold Aquamarine by the legs and then slapped her multiple times before Vice-Versa slammed her onto the ground. As Aquamarine got up, she jumped directly into the air while spinning around with extreme speed and then unleashes a powerful spinning tornado kick with her legs to damage Cerebella that led her to victory.
"You can't win...!" Cerebella said, falling down on the ground in defeat.
"Everyone has a stage fright." Aquamarine grinned slyly.
Arriving in a daytime seaside Dagonian-populated section of New Meridian, Aquamarine started to look around the town of Little Innsmouth as she was still thinking about Painwheel and her revenge against Valentine. But her thoughts were interrupted when she was stopped by a feline catgirl. She has white bob-cut hair and wore a black trench coat.
"How are you still alive when you have full of scars on you?" Aquamarine questioned as she was amazed at the feline's body.
"That is a mystery for your future research." Ms. Fortune smiled. "Here's the deal. If you beat me in a match, then I'll tell you my secret."
"That's kind of a weird request you're giving me, but yeah, you're on." Aquamarine said with a nod.
"I think you're looking for a lab rat!" Ms. Fortune mocked.
"What's holding you together like that?" Aquamarine questioned in wonder.
Nadia ran forward and throw several punches and kicks at Aquamarine, but the bat nurse had blocked them with her bat wings as a protective shield. Aquamarine took the steel claw that belonged to her friend Helia and rapidly throws a deck of shuriken one by one at the catgirl to make them explode on impact, but Nadia quickly dodged the attack and made an X shaped claw at Aquamarine's face while extending her arms. Aquamarine then jumped in the air as her wings spiral down her legs forming a drill at her feet towards Ms. Fortune. After a few minutes of speed and claw attacks, Ms. Fortune took many deep tiring breaths that gave Aquamarine the best chance to finish her off. Aquamarine started to perform a spin in mid-air and held out her arms out to release a swarm of white glowing artificial bomb bats that will begin to hover around her to attack the catgirl that can damage Nadia to her defeat.
"No... no!" Ms. Fortune said, falling down on the ground in defeat.
"Now let's see what makes you tick, kitty cat." Aquamarine smiled.
Arriving in one of the Canopy Kingdom's most illustrious cities, Aquamarine observed the Canopy Kingdom's most illustrious cities and knew as the city of art, culture, and sophistication that played the host to a diverse population of humans and ferals from all corners of the bustling streets that resides many strange and mysterious fighters. But she spotted a schoolgirl up ahead. She has a purple parasite wrapped on her head and mahogany-colored eyes. She wore a school uniform with a pale gray and black color that has a black necktie as it splits in half of her grey shirt, a black higher thigh length miniskirt, a pair of black knee-lengthed stockings, and a little shade of brown shoes.
"Well, well, well." Aquamarine said, gazing at the parasite on Filia's head. "That's quite a strong parasite you got there."
"What are you? A detective?" Samson groaned. " Get out of our way!"
"Not until I get what I'm came for." Aquamarine said sternly. "I need to study that parasite."
"That means you'll have to fight me." Filia said politely.
"Fine by me." Aquamarine scoffed.
"You're about to have...a bad hair day." Samson warned.
"You should really get that removed." Aquamarine smirked.
Aquamarine made the first move and threw a handful of counterfeit colorful bomb gems at Filia to inflict damage while flapping her bat wings to fly in the air. Aquamarine then delivered a combo of rapid and powerful kicks at the schoolgirl as she quickly jumped into the air while kicking in front of her with both legs in a rapid manner to harm Filia. Filia then jumped up and attacked Aquamarine with all kinds of knives, tools, and accessories out of her hair that hit her directly until she made a parasitic hair drill with one leg to knock the bat nurse off balance and jumped up to attack her again with a buzzsaw-like hula hoop. Before Aquamarine could get up and fight, Filia rolled forward with Samson covering her in sharp spikes that damaged Aquamarine. That's when Aquamarine jumped back up and wasn't done yet. Aquamarine gets launched into the air by her bat wings and opened her arms sidewards as her wings sprout multiple arrow-headed attacks to spear Filia. Aquamarine then took the steel claw that belonged to her friend Goshenite and dashes forward to attack the schoolgirl with her tanto from several directions that lead to Aquamarine's victory.
"Sorry, Samson..." Filia said, falling down on the ground in pain and defeat.
"Dammit, kid!" Samson groaned.
"Better run back home, little girl!" Aquamarine said firmly.
After being victorious at her battle with the other fighters in her travel, Aquamarine finally arrived back at the Grand Cathedral. She was observing the hallowed building that serves as a place for the citizens of Canopy Kingdom to worship The Trinity. She quietly opened the doors and was amazed by the place resembling a traditional Catholic church with white marble walls, large stained glass windows, ornate frescoes, and a large imposingly statue. But Aquamarine already realized that the Grand Cathedral was actually the headquarters for the Skullgirl herself. Before she can take her chance to fight her, Aquamarine spotted Painwheel being sadly defeated by a silent nun, who was about to torture the Lab 0's creation. That's when Aquamarine decided to save Painwheel.
"NO!" Painwheel yelled.
"You have failed." Double said with her eyes closed and her hands closed together in a prayer state. "The Trinity is not without mercy. And so we'll make your deaths a quick one."
"Stop, Double!" Aquamarine called firmly as she stood her ground to defend Painwheel.
"So the double-crosser finally drops her ruse. And for what, those experiments of yours?" Double smiled sinisterly as she lowering her hands and opened her frighteningly red eyes.
"This experiment is now my insurance policy!" Aquamarine replied with a smile. "Your fight is with me, not her."
"The Trinity doesn't look kindly upon traitors!" Double recalled as she opened her mouth impossibly wide and transformed herself into her true form: a grotesque monster of distorted flesh and teeth with a crown-like object on her head.
"You disgusted me from the very beginning." Aquamarine snapped.
"I'll gladly accept your tithe...in blood." Double said threateningly.
Once Double quickly shapeshifted into to Filia to attack Aquamarine with a spinning saw out of hair that wraps around her whole torso like a hula hoop, Aquamarine jumped in the air and pointed both of her legs downward like a spiraling drill to dive directly down at the shapeshifting monster. Double then quickly shapeshifted into Cerebella to do a flip kick that launches the bat nurse into the air. But Aquamarine quickly smiled slyly as she viewed Double as an easy opponent until she finally found a perfect chance to strike. Aquamarine performed a spin in mid-air and held out her arms out to release swarm of white glowing artificial bomb bats that will begin to hover around her to attack the shapeshifting nun. Before Double was about to shapeshift once more, Aquamarine took her chance to jump directly into the air while spinning around with extreme speed and then unleashes a powerful spinning tornado kick with her legs to damage Double that led to her victory.
"Forgive me, master..." Double said, falling down on the floor in defeat.
"My bats will mop you up!" Aquamarine grinned with a wink.
After defeating Double, Aquamarine rushed to help Painwheel and gave her a motherly smile on her face.
"You're still not ready, Painwheel." Aquamarine said. "But maybe someday you'll become stronger for your strengths and skills."
"I will get stronger and I will proceed my true purpose, Aquamarine!" Painwheel shouted.
"Good luck with that." Aquamarine said with a kind smile. "But I have to take care of the Skullgirl myself. Don't worry; we'll meet each other again."
"I'll make sure of it." Painwheel said.
"Take care, Painwheel." Aquamarine grinned softly.
As Aquamarine rushed to the stairs and entered inside the catacombs, she was a bit creeped out about the broken ruins of the place and saw a bizarre blue light coming from the Skullgirl, glaring calmly at her as she was really to make her final stand against a determined opponent. She has gray hair with skulls adorning her hair to keep her two ponytails straight and tidy and wore a maid outfit with a blue light hanging off of her back, but her eyes freaked Aquamarine a little bit. The Skullgirl's eyes were blood red that had the shape of half of a skull in both pupils.
"Sorry, Marie." Aquamarine spoke. "I quit."
"We knew this day would come." Marie said calmly. "It was inevitable and inconsequential. Destroying Lab 8 and Project: Peacock were all that was required of you."
"Not really. I have my regrets on doing that." Aquamarine said sternly. "I already know what you really are and why you're here. You're nothing but a pawn, just like me." Her face became fierce and determined. "Even if I die today, my research will aid the labs for generations. I'm coming for you and your masters, monster. Count on it!"
"Enough." Marie said. That's when her voice became almost fierce and demonic.
When Marie raised her arms in the air, the sound of thunder crashes throughout the catacombs. Aquamarine watched the entire place changing itself into a skeletal battlefield. She saw several fragments of broken Trinity statues looming overhead as a full moon shines down onto the arena. With little left to stand on for support, the Skullgirl's raw energy created a makeshift floor in the form of thick, bright blue strands with skulls laced into them with several skulls were littering at the ground.
"You are a traitor to the cause." Marie stated, lifting her arms to bring forth giant skulls to protect around her in battle.
"I'll cut you down to size." Aquamarine spat.
Aquamarine charged forth and jumped in the air and pointed both of her legs downward like a spiraling drill to dive directly down at the Skullgirl. But the Skullgirl felt no pride and summoned a pile of skeletons from the ground to grapple Aquamarine's feet with slight scratch damage before tossing her across the field. Aquamarine got back on her feet and flew towards the Skullgirl to deliver a flurry of rapid powerful kicks while firing a hail of missiles from her wings to attack Marie. Unfortunately, Marie spew out an endless array of skulls that was flying in towards Aquamarine, who was both dodging and getting hit as the same time. Aquamarine then flew up into the air and delivered a combo of rapid and powerful kicks at the Skullgirl. Just as the Skullgirl summons another pile of skeletons from the ground, Aquamarine blocked the attack by raising her left hand above her head and forms a series of black ripple-like waves at the spot where the Skullgirl was standing to damage and disorientate Marie. Sending her opponent a fierce glare, Marie began to lower herself down to the ground while emitting a blue explosion and changed herself into her second form: she was now floating in the air with a black figure created by the Skull Heart floating right behind her. As the shadow flies upward in the air, it quickly came down from above that damage Aquamarine painfully. Lucky for her and her bat wings, Aquamarine repeatedly flew up in front of the Skullgirl and threw a handful of counterfeit colorful bomb gems at Marie. That's when the shadow started to attack when it sunk down into the ground until it then came up to punch Aquamarine from underneath. After Aquamarine blocked the attack, she took the katana swords that belonged to her friend Morganite and slashes Marie multiple times before piercing her stomach and sending the Skullgirl into devastating white ring of solar energy. Feeling weak and pain through her whole body, Marie started to change into her third and final form. After letting out a loud painful scream, Marie was now an organism with merely bones surrounding the Skull Heart as its energies was keeping her together. Marie then spew out an endless array of skulls to fly towards Aquamarine, but the bat nurse flew high in the air and delivered a combo of rapid and powerful kicks to damage Marie. But the Skullgirl quickly send out the shadow to attack, leaving the shadow to jab at Aquamarine and send her flying across the battlefield with moderate damage. But Aquamarine wasn't ready to give up and knew the exact move to beat the Skullgirl. Aquamarine used her bat wings to fly up in the air in front of the Skullgirl to perform a somersault with her right arm towards the opponent and brought her feet down on Marie to deliver a rapid series of kicks at extreme speed that stirs up harmful white energy currents. Marie gave one last scream in pain and her entire body began to vanish out of the battle, leaving the Skull Heart behind.
"The Heart is now MINE!" Aquamarine said determinedly.
After defeating the Skullgirl Marie, Aquamarine took her possession of the Skull Heart as she took a very long look at it for her decision to be made.
"It is done." Aquamarine breathed. "Now, what should I do with the Skull Heart?" She closed her eyes shut and think for a moment as she was thinking about her friends: Goshenite, Maxixe, Morganite, and Helia. "I really miss my friends so much that I fell into a stupid mistake. I love gems and jewels throughout my entire life, but they are more important. I'll be waiting for them." Her eyes opened up in determination. "Skull Heart, I wish my Last Hope return to me!"
The Skull Heart begin to flash as it bathed the Aquamarine into bright light once she covered her eyes to notice that four familiar women were coming out of their corpses well and healthy.
After her journey on battling the Skullgirl was over, Painwheel arrived to find Aquamarine and her friends in the catacombs, where they welcomed her in the team. Painwheel felt graceful and quickly removes her mask. As everyone gazed up at the sky, they have business to do with Lab Zero.
