Ladies and gentlemen, I give you a crossover story that you will all love. This idea is from Dfrab on DeviantArt.
WARNING: I DO NOT OWN LEGEND OF KORRA, TMNT AND WINX CLUB OR ANY OF THE CHARACTERS.
The Northern Water Tribe, a nation with waterbenders. The two chiefs were Eska and Desna, twin children of the former chief Unalaq, a man who betrayed his own tribe for power. Unalaq tries to fuse with Vaatu, a powerful spirit of darkness, but he instead fused with Raava and Korra, becoming the Avatar of the Balance.
For his crimes of hunger for power against humanity and peace, Unalaq was bounded in chains in the Fog of Lost Souls for five long years after Harmonic Convergences.
Meanwhile, at the northern spirit portal, where a purple portal was appeared. Four identical men in suits emerged from the portal. These men were Kako Naso, Duke Acurades, Torrinan, and the leader was Ch'rell. The very same alien who made a deal with the now-deceased Supreme Witch Meldora. They stare at the spirit portal.
"This is the portal to the Spirit World." Ch'rell said. "This is where we can find him."
"But how can we when we have no idea where he is, Ch'rell?" Duke Acurades asked.
"We have something of his that our friend has enchanted, my friends." Ch'rell said before he holds a northern necklace of a chief. "With this, we'll be able to locate his prison."
"He's been in there for five years." Kako Naso said. "During Harmonic Convergences, the Dark Spirit, Vaatu merged with the Avatar and defeated him and the Fire Princess Azula. Then Vaatu bounded him in chains somewhere in the Spirit World…"
"Yes, yes, for five years for his crimes of manipulation, attempted murder and his hunger for more power." Ch'rell said with a grin. "We all know the story."
"So, why do you and our ally think he will join us in our plans?" Torrinan asked.
"Have faith, Torrinan. If it hadn't been for the Triceratrons and those blasted turtles, Kraang Prime would have been alive." Ch'rell said. "With him as recruit on our side, they will pay for his demise, along with those human friends of theirs, those Mutanimals and the Utrom slim that had wronged us. Long live Kraang Prime."
"Long with Kraang Prime!" the identical men shout before both the members of the Kraang entered through the portal.
They were walking through the Spirit World, then they wander about a mysterious spirit forest. The necklace around Ch'rell's neck glowed.
"I think we are getting closer to our new friend's prison." Ch'rell said.
"I've always wondered what the Spirit World would look like." Kaso said. "And I hope Republic City's looking marvellous these nowadays."
"Even with Korra." Torrinan said. "I must say, Ch'rell, you were right about her having a lovely name."
"Yes, normally I would hate humans. I maybe a ruthless warrior for the Kraang, but I am also a gentle-Utrom." Ch'rell said.
The Duke was thinking. "A place where only the lost will ever find you. What do you think that place might be?"
"Let's ask it." Ch'rell said before he stands outside the hollow of the tree where the dark spider scorpion spirit resides, where Tenzin, Kya and Bumi went to find Jinora five years ago. He attacks the spirit with a laser blast. "Hey, you! Spirit! Wake up!"
The spirit was awaken from its slumber, it felt their presence and realized what they really were. "Kraang…" It shakes in fear.
"Yes, my fellow spirit, we were part of the Kraang. I'm dreadfully sorry that I woke you." Ch'rell said in a gentle tone. "We are looking for a place where the lost can find you."
"I-I know where it is. I can take you to it." The spirit said fearfully.
The spirit emerges from the tree and leads the Kraang members to the Fog of Lost Souls.
They arrived at the Fog, which was a canyon with sharp rocks. The view of the inside of the canyon was still obscured by a thick fog.
"The Fog of Lost Souls. That's where Vaatu imprisoned the former chief and where we can free him" Ch'rell said.
The four men jumped into the canyon. The gravity matter on their shoes begins to keep them from falling to their deaths. They slowly landed on ground. They wander off in the Fog searching for who they were looking for.
"What does this fog do, Ch'rell?" Torrinan asked.
"The Fog of Lost Souls is a spirit prison for humans." Ch'rell explained. "This fog is actually a spirit that infects your mind and slowly drives you mad, imprisoning you in your own darkest memories."
Ozai, who had grown old since the time of Aang, walks by them.
"I am Ozai, son of Azuln! I am the Phoenix King! I will seek vengeance on the Avatar. I am Ozai, son of Azuln. I am the Phoenix King. I will seek vengeance on the Avatar."
Ch'rell and his comrades watches him going mad. "That for example. But not the one we're looking for."
"How come it won't work on us?" Kako Naso said.
"That, Mr. Naso, is because we are not human." Ch'rell said before the necklace glows brighter and brighter. "It seems we're almost close to him. And he would be that way."
The four aliens walked until they had found who they were looking for. Unalaq. He was still bonded in chains. After five years, he looked like a madman. He's hair grew wild, he got himself a beard and his eyes were like an insane prisoner.
Ch'rell walks to the imprisoned Unalaq. "Hello, there. We were hoping we could find you here…"
Unalaq shackles his chains and screamed madly at the aliens. He yelled and tried to attack them, but he was still bounded. He laughs insanely.
"Sprits and humans are one. We are one. I was meant to be their new Avatar. Me! Unalaq, chief of two tribes! I AM THEIR CHIEF! I AM…"
"Oh, get a hold of yourself, man!" Ch'rell smacked Unalaq, making him tripped on the ground. "You've been in here for five years long. It's time you'll get out."
Unalaq stared at the leader with a concerned look. "How did you find me?" He looks at his old necklace. "And where did you get that? It was mine."
"Our friend enchanted it so we can find you. She and I need you to join our little organization." Ch'rell explained. "Now, do you still remember your name?"
"I remember it too well. I remember. I remember. Unalaq is my name." Unalaq muttered. "I remember, that I was chief of the North. I was chief of two tribes. I tried to bring balance to sprits and humans."
"Bring balance to spirits and humans." Duke Acurades said. "How would you do that?"
"I was destined to be their new Avatar. A Dark Avatar. I was supposed to fuse with Vaatu. We would have led them all to a new age of spirits and humans." Unalaq said with a braking voice as he starts to cry for his defeat.
"Dark Avatar, you say." Ch'rell said in an amused tone. "What happened?"
"THAT SCUM! He betrayed me!" Unalaq said before he stands up. "He rejected me and fused with the only enemy he was supposed to destroy: The Avatar. My niece, Korra."
"Then the two Sprits of Light and Darkness in her body and rebooted her into the Avatar of the Balance. We know the story." Ch'rell said. "Which is why we'll free you. If you will join us."
"Join you. Yes… Join you to take back the world. Join you to kill them. Join you to kill my brother, his wife and those fools in Republic city that helped her. join you to destroy the Avatar Spirits. JOIN YOU TO KILL THE AVATAR OF THE BALANCE!" Unalaq roared in the Fog as he and Ch'rell stared at each other, face-to-face. "Revenge… I must have revenge."
"And you will, Mr. Unalaq. So, tell me something I must know. Our friends from the Red Lotus told us you have a connection with them." Ch'rell said. "Have you had anything belongs to Zaheer and P'Li? Perhaps hair?"
Why did Ch'rell released Unalaq from the Fog of Lost Souls?
Chapter two will come.
