The royal mermaid family has arrived in the king's throne room, where Ivanka sat comfortably on King Neptunium's throne. She knew that they will start a mutiny against her, nor do they had found the crystal pearl that she has asked for. But none of that matters to her nonetheless. The witch still has the sea king's trident in her hand. She risen from the throne, tall and mighty as the sea king once was.
"So you haven't found the crystal pearl for me?" questioned Ivanka sharply.
"No! But you will never get your hands on it, Ivanka!" shouted King Neptunium in a strong position. "Not while I'm still king! I shall defeat you again!"
"Oh really now?" taunted Ivanka. "You and what army, King Neptunium!?"
"Perhaps I don't need an army to be rid of you, sea witch!" growled King Neptunium. "I'll just take back my rightful place on the throne!"
"Well then, come and get it back!" says Ivanka as she prepare for battle.
King Neptunium turns to his daughters.
"Go and find somewhere to hide!" King Neptunium said to his daughters. "This is a battle that I shall face myself."
The mermaid princesses all swam away from the battle that is soon to begin. Once the girls hide behind the golden shells, King Neptunium grabs a weapon nearby and charges at the dark sea witch in full speed. Thus their battle ignited. Meanwhile on the other end of the castle, Prince Kellan and his brethren fought with the sea witch's henchmen. The fight is not very easy for the giant creatures had the upper hand whilst nourishing their jaws. Both Nexus and Grillar were about to take a bite on the humans. But with his sheer brute strength, Lou thwart the assault by striking their faces. Jasper transforms into a giant squid to help the unlikely heroes fight back. Although he is afraid, Jasper did it for his friends. Olaris aids the girls on the defense while the men fought on the offense. Lou distracted Grillar by holding onto his jaws with the chains, giving Axclius the window of the opportunity to deliver the final blow with his sword. Thus Grillar the mighty gulper eel is defeated. Now Nexus is the last one standing his ground. As the sea serpent blasts his inferno rays directly from his mouth, Princess Maya swiftly deflects the attack from her suit's shield. The power indirectly destroys Nexus. The battle has won for them.
"Yay! We did it!" cheered Olaris.
"Wow! I can't believe this! We all won!" cheered Jasper as he turns back into his fish form.
"There's nothing we can handle." says Julio, showing off.
"Alright, Julio. Don't get too full of yourself, mister hot-shot." said Axclius.
"But let us not celebrate our victory just yet." said Dorian in his English demeanor. "There is still much to be done."
"He's right." says Prince Kellan as he swims closer to the group. "We got to go help Valorinna's family. There's no way I'm letting her down. Not now."
"Well follow me, everyone!" says Lou as he leads the pack.
The heroes swam off into the castle's halls. As they were storming the hallway, their advance is at an immediate halt when the Hydro-Trix appears to end them.
"And where do you pathetic humans think you're going!?" sneered Cyclonya in a fit of rage.
The heroes prepare for the next battle against the sirens.
"Get out of our way!" demanded Prince Kellan.
"Not going to happen!" taunted Sub Zero, flicking her long white hair. "We are ordered by the mistress sea witch herself that we'd take good care of the anomalies."
"And besides, we had some unfinished business to settle with you!" snapped Malevolent.
"But we trapped you, mean sirens!" shouted Olaris in disgust.
"How did you get out of the cave?" wondered Jasper in shock.
"Oh you silly fishes! There is a lot of things you don't know about what we're capable of." snickered Malevolent.
"I'm not going to say it again!" shouted Prince Kellan, drawing his sword. "Get out of my way!"
"Or you'll do what exactly, princey boo!?" teased Cyclonya.
"Ok, enough talking!" said Sub Zero as she powered her ice spells. "Let us exterminate these unwanted pests!"
"Oh now you're talking, big sister." Cyclonya complied with a grin.
"I'd be delighted to." Malevolent complied with a grin of her own.
Thus the trio of sirens begins to attack the brotherhood. Sub Zero freezes Princess Maya, Emmy, Lou, Olaris and Jasper into a block of ice, trapping them. Now the men are at the mercy of the Hydro-Trix. Before they could free the others, the Hydro-Trix use their siren song to bewitch them. Unable to resist their song, the males of the brotherhood approach them with their defenses down.
"No! Don't listen to them, guys!" screamed Lou as he tries to break himself free from the ice. "You have to resist their song!"
But the men were too enchanted by the song to heed the merman's warning. The brotherhood were powerless to the sirens. All under the magical influence of the heavenly voices. Thus leaving the Hydro-Trix to take advantage of their vulnerability and then destroy them. If the others don't do something and fast, all will be lost forever. Luckily for them, the wetsuits Princess Maya provided for the group have all sorts of modes installed into the system. Such as body heater, silence mode, free movement and everything else. She activates the body heater to thaw the ice, long enough to get herself free. Then she turns on the silence mode into the men's helmets automatically, to block out the sirens song. The Hydro-Trix were enraged by this action.
"What's this!?" screeched Sub Zero in question.
"How can this be!?" screeched Cyclonya in rage.
"No man has ever resisted our song!" screeched Malevolent.
"I should thank my father for that!" boasted Maya as she shows off her wetsuits manual. "He has been granted the title 'Genius King' for something! Before his death, he installed all sorts of features into the wetsuits. Including silence mode! It blocks out any noise around the person who is using the suit, even the sirens song! Ha! Looks like your talent show has been cancelled!"
"CURSE YOU, HUMAN GIRL!" screamed Cyclonya in rage.
Being the hotheaded siren that she is, Cyclonya charges at Princess Maya at full speed in the attempt to attack her. Before she could end the princess, Dorian made quick work of her with his summoning power. Now he has ended her first.
"Thank you for that." Princess Maya thanked him.
"You're welcome, your highness." Dorian replied in a noble manner.
Now the princess frees the other group from the ice by using her suits heat ability. Cyclonya has dissolved into black sea foam. Angered by the death of their youngest sister, Sub Zero and Malevolent went all out on the brotherhood. With their shadow and ice powers combined, they endangered the heroes with every chance they get. The battle with the two remaining sirens will not be as easy as they all thought. Sub Zero endangers the brethren by shooting her ice spears at them. Julio and Axclius deflects the ice with their swords. But for how long? This just in, Julio has an idea. With the wetsuits heaters, he combined his sword with the suits' system, creating a massive heat blade. Axclius acts as a diversion, leaving Julio the opportunity to catch Sub Zero off her guard. With his sword at three thousand degrees, he strikes the cold siren down. The unbearable heat temperature melts Sub Zero into a frosty sea foam. Now what it's left is the dark siren Malevolent. And the other crew is battling her. She tries to reach into the darkest depths of Dorian's subconsciousness. He tries to resist her powers but to no avail. He nearly could've surrendered to her if Emmy, Olaris and Maya hadn't intervene. The young women fought the siren off, to free Dorian from this mental torture. Malevolent nearly had the upper hand with her terrifying shadows but Olaris thwarts the attack by shedding the palace lights directly at her. Due to the darkness's weakness to light, it destroys Malevolent. Now she turns into black sea foam. Thus the battle is over for now. They must hurry to the throne room if they were to aid the mermaid family. Inside the throne room, King Neptunium and Ivanka fought harder than ever before. Neither of them are backing down as they both clashed with raw power and formality. The mermaid princesses are horrified by the event. Their father did his best that he could but as the turn of events took its toll, Ivanka triumphs over him. While the king is knocked down onto the floor, the sea witch points the trident closer to his neck.
"You have lost, King Neptunium." snarled Ivanka in a sinister glee. "You may have defeated me from before. But now, I've turn the tables and defeated you. Just face the reality, you are getting weak!"
King Neptunium glared at the sea witch. Just as Ivanka use the trident to burn the king's neck, the brotherhood arrived just in time to knock her trident loose. The angry Ivanka turns to her opposers.
"How dare you, humans!" screeched Ivanka in rage. "You think that you all have what it takes to stop me!?"
"Oh believe me, sugah! We've handled worse!" taunted Emmy with a sassy wink. "And you are no different."
"Yeah! What she says!" added Julio.
"You will leave the mer-people alone!" yelled Prince Kellan as he prepares his summoned sword.
"Never!" Ivanka snarled. "And I have suffered your interference long enough! I shall be rid of you all!"
"Lady! You're welcome to try!" says Axclius, cracking his neck and knuckles.
The dark sea witch risen the trident in her hand and it glows into a frightening shade of green.
"Are you ready, you pitiful insignificant humans!?" says Ivanka as she prepares for battle.
"We're ready when you are, witch!" said Prince Kellan, readying his sword.
Then in the moment's past, the final battle ensues. The brethren attacks the dark sea witch together. Lou, Olaris and Jasper swam by the little mermaid's side. They wanted to make sure that she is okay.
"Are you alright, Valorinna?" asked Olaris as she hugs the princess.
"Oh Olaris. I wish I knew." cried Valorinna, hugging her friend back. "I'm so scared for every one of you."
"Don't worry. We are not going to leave your side again." says Lou.
"Yeah. No matter what happens here, we will always be friends to the end." said Jasper, hugging the mermaid's tail.
"Oh you guys..." Valorinna uttered softly in relief. "I'm so glad you're all here with me."
She hugs her friends closer to herself. During the ordeal, the brotherhood fought the sea witch in numbers. They collaborate their attacks to overwhelm Ivanka, backing her into a corner. Valorinna's sisters tries to pull their father out of harms way. With their strength in numbers, it may seem like the crown prince and his brethren are winning the battle. But they are going to find out how wrong they were again. Feeling rather annoyed and infuriated by their efforts, Ivanka use the trident's power to create a massive deathly shockwave, harming everyone in the throne room. The royal brotherhood were stunned by the attack and the mermaid princesses are all badly hurt along with King Neptunium. Ivanka's tentacles snatched Lou away from the little mermaid. She then slams the mutant merman onto the ground next to the brethren. Valorinna watch in utter horror as Ivanka toss Princess Maya right towards the pillar, injuring her. Then she is about to destroy everyone with the trident poised in her hand. Starting with Prince Kellan himself. Since she couldn't bare to see everyone she loves get hurt, Valorinna sprung out from the golden shells.
"No, Valorinna! Don't do it!" cried Olaris as she tries to stop her.
"Valorinna! Stop!" cried Jasper out of fear.
The little mermaid Valorinna swam into the fray. Just as Ivanka is about to destroy Prince Kellan.
"STOP!" screamed Valorinna.
This just in, a unknown energy filled the room. An energy so pure that every one creature can feel it from a foot away. It must be coming from the little mermaid's soul. Ivanka paused her attack after feeling the signature energy. That is when she knew the legendary Crystal Pearl is closer than she thought it'll be.
"I know that familiar energy!" says Ivanka as she then stands down. "It is the same energy from before! I knew I was right all along!"
She slowly turns to Princess Valorinna.
"It was you!" snarled Ivanka as she approaches Valorinna.
"Swim away, Valorinna!" shouted Prince Kellan, although injured. "You gotta get away from here!"
But before Valorinna could escape, Ivanka entrapped her with her tentacles at high velocity. Now she is at the mercy of the wicked witch of the sea.
"The legendary crystal pearl is not so far from one's reach after all." said Ivanka as she towers over Valorinna. "It is been inside of you all this time. You have gotten possession of it somehow and I didn't realize it until now."
Ivanka wraps Valorinna up in her tentacles grasp. Then she turns to King Neptunium, whom is still injured from the fight.
"You truly are a fool, King Neptunium." said Ivanka as she went on. "Did you actually think that you can keep the crystal pearl hidden out of sight? Perhaps you are the one who didn't realize that you and your daughter are making this way too easy for me. This is so funny, even I know that it is futile! Ha! You all have played your roles all too well!"
"Daddy. What is she talking about?" cried Valorinna in distress.
"Go ahead, King Neptunium! Tell her!" boasted Ivanka in a wicked flair. "Tell her the real reason why you kept her and her sisters sheltered away from the outside ocean world!"
Defeated by the turn of events, King Neptunium gets up on his own tail and he is compelled to tell his daughters the real truth.
"Oh my sweet little Valorinna. I cannot keep the truth from you and your sisters anymore." grunted King Neptunium in pain. "I'm afraid that Ivanka is right. The true reason why I kept all of you sheltered away from the outer ocean worlds, is because I have received news from the council gods that one of my beloved daughters has been in possession of the legendary crystal pearl. And that is you, Valorinna."
The mermaid princesses gasped and are in shock by this startling revelation. Even the prince's brethren were shocked by what the sea king has shared. Lou, Olaris and Jasper were also stunned by the news as well. Valorinna can't believe her own ears. All her life that she spent, defying her father's rules just to endanger everyone else around her. All of this is because he wanted to protect her and the rarely seen crystal pearl. Now she feels even more guilty about it than she has been before.
"I have the crystal pearl all this time?" Valorinna questioned softly. "I don't understand. When were you going to tell me about all of this?"
"Believe me, my dear. It's been tearing me apart as well." says King Neptunium. "I swore to the council gods that I keep quiet about the crystal pearl and its new whereabouts. Until it has been found. And I made a promise to your mother before she died on her deathbed, that I will protect this family. More than anything, I have wanted to tell you and your sisters the truth. I only wanted to keep you all safe from harm."
Ivanka spoils the solemn mood as she still holds onto the little mermaid.
"Well now thanks to your efforts, you have failed miserably!" scolded Ivanka as she turns to face Valorinna. "As a result, I get to take it all for myself! But first, let me drill out my final prize!"
"Don't you dare hurt her!" Prince Kellan yelled as he struggles in pain.
She holds the little mermaid still in her tentacles as she is about to use a painful spell on her.
"Oh don't you worry, dearie. This will only sting a little." snickered Ivanka as she drills her dark magic into Valorinna. "Or it'll sting much."
Valorinna screams in pain as the process went into full intuition. Everyone watched in pure terror as Ivanka's dark magic spell drilled into the mermaid girl's very being, piercing her soul. They were all powerless to stop her. Then in an instant, the legendary crystal pearl has finally appear right out of Valorinna's body. The dark sea witch drops Valorinna's weak body down on the floor. With the crystal pearl right into her hand, Ivanka has accomplished her latest conquest.
"At last! The king's throne, his trident and the legendary crystal pearl, is all mine!" bellowed Ivanka. "Now what is left is to conquer all of Aquamarinia!"
Ivanka ate the crystal pearl whole with a mouthful. Then what is happening next is unimaginably terrifying for everybody in the kingdom. The dark sea witch's body transforms into a humongous mass of formless black negative energy, swallowing everything and every one creature in the endless oceans. The witch's power consumes the entire aquatic planet of Aquamarinia, plunging the world into an everlasting nightmarish darkness. All of the sea creatures have fallen prey to the sea witch's whim. Their habitats are corrupted and it is turned into a hellish landscape. The mer-people of Siren-Millennia have been overwhelmined into fear and despair. The horrific images of demons and spirits plagued the darkness. From the black void, Ivanka's giant monstrous face and hands formed itself out of dark green malice. Before one could knew it, Ivanka the dark sea witch has become something more sinister and powerful. She has not only just become a void of pure evil, but ultimately the embodiment of all the darkest oceans.
"I am Ivanka! Your new goddess of Aquamarinia!" she bellowed in a distorted demonic voice. "And you all will worship me!"
Valorinna and her sisters tremble in fear. Refusing to back down now, Prince Kellan and his brethren resume their battle with Ivanka. Even Princess Maya aids them in the assault. But their efforts are in vain for their weapons could barely even touch the formless monster witch. Then she overwhelms the royal brotherhood. They couldn't grasp the true nature of Ivanka's assault. The sea witch swallows them into the darkness. With her horrifying imagery, The humans' worst nightmares have come to light. Lou and the tiny friends tries to help the other heroes, but even they were consumed by Ivanka's hellish influence. Their screams can be heard from the darkness, horrifying the princesses. Maya helps Valorinna and her family as they tried to escape. Unfortunately for them, there is nowhere to swim. Then suddenly, Ivanka overwhelms Princess Maya, swallowing her into the dark void. Valorinna couldn't even help her now. Then she turns around after hearing her sisters scream. They are all surrounded by Ivanka's darkness.
"I'm so scared!" cried Onna.
"There is no escape for us!" screamed Leila.
"The sea witch is too powerful!" cried Trista.
"Now what are we going to do!?" Fayna cried in fear.
"I don't know!" says Onya. "Should we pray happy thoughts!?"
Daphnia swims over to hug Valorinna.
"Oh Valorinna. I'm so sorry that this had to happen to you." says Daphnia.
"I'll be fine." said Valorinna, hugging her eldest sister back. "I'm just worried about you guys."
"That's sweet of you, little sister." said Daphnia. "You really had us worried about you. Why did you run away from home?"
"It is because I was fed up with being a crown princess here." Valorinna explained. "All I ever wanted was to prove that the world isn't as dangerous as father said it was. But I guess I was wrong, am I?"
"It doesn't matter right now." says Daphnia as she smiles a little. "You are here with us. We are a family again and I love you very much, Valorinna. We all love you."
"I love you too, Daphnia." cried Valorinna. "I love all of you sisters."
They were all touched by her words. The mermaid princesses hugged one another. But then, their heartfelt moment is interrupted by Ivanka's whims. She threatens the royal girls into succumbing to the darkness. Before her dark mass could consume them, they were suddenly protected by King Neptunium. He stood his ground to push back the darkness, biding his daughters the time to escape.
"DADDY!" they screamed in unison.
"I can't hold her back any longer!" shouted the sea king. "Go now!"
The little mermaid and her sisters all swam away to find a safe place in the darkened castle. King Neptunium used what is left of the castle's magical technology to hold the darkness back. But it was no use for Ivanka consumed him into the massive void. Now the sea witch's darkness is pursuing the princesses. Her power chased them all over the palace, eventually leading them back to where it all started in the throne room. They found themselves cornered in the middle of the floor. Ivanka pokes her monstrous face out of the darkness and she is now glaring at the royal mermaids.
"Foolish girls! Did you really think that you can escape from me!?" taunted Ivanka in a terrifying demeanor. "Must you know that I am Aquamarinia! You cannot run and hide from me! I'm everywhere!"
She then swallows up each mermaid princess, one by one. Valorinna is the last one left hovering in mid water. She could hear her sisters screaming from the darkness, leaving her petrified. She watches in sheer terror as Ivanka overwhelms her sisters with demonic nightmares, until all six of them have fallen in complete despair. Then the sea witch's crackle can be heard from the darkness as well. The formless monster appears before the little mermaid, surrounding her with her gigantic claws.
"Now you are all alone, little mermaid princess!" crackled Ivanka, torturing her victim. "Take a good look at everyone you have ever loved! Your friends, your family and your heroic crown prince! They all had succumbed to my new power! I have made their nightmares into reality! And now you will fall to my whim as well."
After the formless monster sea witch shows her the fate of everybody she loved, Valorinna sunk onto the floor in despair. In her fearful sorrow, she sobs away. Ivanka is pleased with what she had wrought onto the oceanic planet as a whole, in opposition to Valorinna's chagrin. It seems that all hope is lost for her now. All of the other sea creatures outside of Siren-Millennia has already succumbed to the dark aura. And so did the mer-people. Inside of the darkened palace, Valorinna looks around her new horrid surroundings.
"This is so terrible." cried Valorinna in utter despair. "My father, my sisters, my friends and my prince Kellan! It looks like my worst nightmare has come true. I'm so alone! I can't do this by myself..."
"You are right about that, dearie!" taunted Ivanka. "Your worst nightmare has come true. And I attend to keep it that way. But don't you worry, it'll all be over soon enough! Once that I'll destroy you along with the anomalies, I'll see to it that there will be nothing left of you! That I will promise!"
Valorinna weeps with her pain and heartache. Ivanka prepares to use her final fatal assault on every living thing on the corrupted Aquamarinia. But before she can devour the little mermaid first, Valorinna's newly salty tears flows into the darkness, reaching the corrupted crystal pearl entirely from within. The mermaid's tears purified the crystal pearl and it has heard the mermaid princess's cries. Then all of a sudden, it sheds its bright light through the darkness, hurting Ivanka. The light burn the formless monster sea witch, leaving her screaming in pure anguish. It escapes from her void and found its way back into Valorinna's hands.
"It's the crystal pearl!" exclaimed Valorinna in surprise. "It came back to me! So you must've chosen me for a reason. Is it because I have a pure heart?"
Although in agonizing pain, Ivanka refuses to give up the crystal pearl and its power so easily. She tries to scare Valorinna into handing the crystal pearl back to her.
"No! This can't be!" screeched Ivanka monstrously. "I demand that you give me back the crystal pearl! Give it back! Only I can have its power! It is no use for you!"
"So this crystal pearl must have such incredible power." says Valorinna as she turns to face Ivanka. "Or you would've wanted it so badly."
"I'M NOT GOING TO TELL YOU AGAIN!" Ivanka demanded ferociously. "GIVE THE CRYSTAL PEARL BACK TO ME! IT DOESN'T BELONG TO YOU! IT BELONGS TO ME! SO GIVE IT BACK!"
The little mermaid finally summons her courage to stand up to the formless sea witch. She has had enough of her and all of the harm she has wrought onto everybody else around her. With the crystal pearl in her possession again, Valorinna bravely swims forward to the face of Ivanka and positioned herself to fight back against the witch's darkness.
"Well since you have asked me very nicely, you can have it!" Valorinna clapped back as she raise the crystal pearl in front of her.
The crystal pearl begins to glow blindly bright as it reaches its full potential. Within the right moment to spare, she use the crystal pearl's majestical power to eliminate Ivanka once and for all. It fatally destroys the dark sea witch and the darkness along with her. In her final death cry, Ivanka is no more. The crystal pearl's light restores the planet's natural habitats from end of the ocean to another. The marine mammals are free from their nightmares, the reefs are returning to what they were before, the skies above the sea are cleared from the black clouds and deep underwater, all of the merfolk are happily soaring through the crystal clear waters once more. The enchanted kingdom of Siren-Millennia is beautiful again. And it is all thanks to Valorinna and the crystal pearl she now holds onto. Thus the prophecy has been fulfilled.
