Ryuki was looking his sister up and down, "New clothes?"

Kat flipped her hair and said, "Oh, don't you know? Red and black is so in this year!" She then clenched her fists. "And so is black and blue, but don't take my word for it, you should try it."

Sokka then inquired, "Um, Ryuki? Do you know her?"

"She's my sister."

(30 seconds of complete silence.)

"WHAT!?"

"YOUR SISTER IS WITH THE FIRE NATION!?"

"YOUR BROTHER IS WITH THE AVATAR!?"

The twins' ears rang at this.

"Yes, she is," Ryuki said, sighing.

Kat admitted shamefully, "Unfortunately…"

"Well, now that we know everyone here," Azula produced a blue flame, making Ryuki's eyes go wide, "Capture the Avatar and kill the rest!" She commanded.

"This is gonna be fun," Mai smirked.

"Ooh! I wanna fight the boy in blue!" Ty Lee raised and waved her arm enthusiastically and jumping up and down, "I think he's cute!"

Mai, Azula and Kat turned to stare at the gymnast while Aang, Katara and Ryuki turned to stare at Sokka.

Azula rolled her eyes. The pink acrobat could have the strangest tastes sometimes. "Fine, Ty Lee." She sighed. "You can fight the water peasant boy."

"YAY! You're the best, Azula!" Ty Lee then dashed towards Sokka.

"Leave my brother to me!" Kat jumped in. Azula smiled graciously.

"Certainly. I know a thing or two about brothers if you want to know," Azula offered.

"Kay, Azula-ojou-sama!" Kat yelled out before revealing the claws on her fingertips. She slashed down on her brother who sidestepped the strike. She then went into a roundhouse aimed for his head but he leaned back before retaliating with a powerful forward kick to her chest, sending her flying back.

Toph was fighting against the Fire Nation kunoichi, Mai, and the girl was throwing her knives at the Blind Bandit, targeting Toph's neck. Toph listened and heard the knives whizzing towards her. She pulled up several earth shields before sending a wave of rocks at her opponent.

Azula was up against both Aang and Katara, both of the latter using Waterbending against Azula's advanced Firebending skills. Azula sent blue spurts of fire at them and they doused them out with water.

Ty Lee and Sokka were, well…

"Oh, you're just so cute!" Ty Lee cooed as she struck with fast jabs and punches. "Come on, cutie, let me take you home so that I can show you what a good time is really like!" she winked at him playfully.

This was weird to Sokka on so many levels. This girl was, he admitted, cute and quite pretty and her choice of clothing really showed off her sexy figure. On the other hand, she was from the Fire Nation. Pretty or not, she was still going down. He swung his machete at her and she playfully flipped back before jumping at him. She then pecked him slightly on the cheek. He stood frozen by this action. This caused her teammates to groan.

Kat, in the meantime, was taunting her brother. Both were using their martial art skills. While Ryuki only wanted to bring her down, Kat wanted to take his life. They were also talking as they fought.

"Why are you doing this, onee-chan?" Ryuki demanded as he blocked a right hook.

"Maybe you should narrow it down, little brother," Kat said as she jumped over a roundhouse kick. "I've done a lot of things."

"Why are you working with the Fire Nation? Do you know what they're capable of and what they're attempting?" He threw a punch at her.

She caught his fist and then elbowed him in the chest, taking the wind out of him. She then flipped him and he was facedown on the ground. She stood above him and twisted his arm. He grunted in pain. She purred. "Of course I do. They want to dominate the world and I say they should go for it! It's the law of the jungle here, Ryuki. Survival of the fittest! The strong shall live and the weak will die!"

Ryuki concentrated and shoved her off with his telekinesis. She dug her heels into the ground so that she wouldn't fly off. "Innocent people will get hurt, onee-chan!"

Kat casually flipped her hair and replied coldly, "So what?"

"So what? So what!? Don't you even care?" Ryuki said in an attempt to reason with her. She shrugged.

"Not really. Should I? This isn't really our world, little brother, so why should I care what happens to it?"

"You coldhearted…" he growled.

Kat snorted. "Why are we wasting time with this petty bickering?" She clicked her claws. "Time to get serious!" She then charged at him. He did a back flip and jumped onto a tree. He then sprung himself at her and delivered a clothesline that caught her by surprise. He then dug both his feet into her chest and pushed her back with great force. Kat growled. "Oh, yeah! This is gonna get serious!" She then produced hot blue flames like Azula and threw them at Ryuki.

Azula changed tactics and began throwing lightning bolts at the two benders. They dodged out of the way and if they attempted Waterbending, they could get a bad shock. Aang decided to blow Azula back with a wind blast that blew her off her feet but she quickly recovered before blasting blue flames at the Avatar.

"Give yourself up, Avatar! You may have us outnumbered but we have you outmatched!" Azula sneered.

"No way!" Aang stomped his foot on the ground and it blocked the blue flames before crashing into Azula. The Fire Nation princess was sent flying before a water blast from above, courtesy of Katara, stormed down and blasted her to the ground.

Mai was running out of knives and had to dodge from Toph's flying rock.

Ty Lee was still playing around with Sokka who didn't know if he even wanted to hit this girl at all.

Kat's hand had gripped Ryuki by is throat and pinned him against a tree. She curled the fingers of her free hand into a claw and grinned. "Any last words, dear little brother?" She squeezed his throat, cutting off his air. She taunted, "What's the matter? Cat got your tongue?" She began to laugh. "You know what's so funny? I bet you didn't even tell them about your powers, especially your primary one." Ryuki's eyes widened. "I mean, the Fire Nation is evil and thus all Firebenders are evil too, right? You don't want them to hate you so that's why you didn't tell them about your gift. Isn't that right?" Ryuki looked away. "Don't lie because I can see it in your eyes!" Ryuki began to growl. "What was that?" Kat mocked and leaned closer.

POW!

Kat got powerful fist in the stomach that caused her to double over and let go of him. She clutched her stomach.

"Shut…up…" he growled, eyes narrowing. Kat smirked.

'Go ahead, little brother, show them who you really are…'

With a feral cry, Ryuki fired ice beams at Kat but she then waved her arms to erect earth shields from the ground. Azula smirked, watching this. She now knew that Copycat could do more than mimic looks.

Ryuki changed tactics and turned to sand, blasting towards his evil twin sister. She pulled her goggles over her eyes and tucked her head in as she crossed her arms over her body to block and defend herself from the blast of sand. Her exposed stomach got scratched up a bit but nothing she couldn't handle. He reformed himself behind her and then performed a kick into her back. She whirled around and grabbed his leg before giving a twist that sent him falling. He pushed himself back up with his hands and spun his legs around to force his sister back before flipping back to his feet, leaping over Kat. He then grappled with her.

Kat could see it now, the flame in her twin brother's eyes. All she needed now was the oil to cause it to come forth. "I should just kill all your friends right now. There's no way you can protect them. You couldn't even protect Tazuka."

That did it.

He snapped.

"RAAAAAAAAAAAAARRRRRRRGGGGGGGGGGHHHHHHHHHHH!!" Ryuki roared and then he breathed a blast of flames at her face from his mouth. She teleported away.

Everything stopped. Everyone one of Ryuki's new friends held a shocked expression on their faces.

Sokka yelled, "You can Firebend!"

Ryuki looked at everyone. 'Oh, Kami…'

Kat smirked. She then took out her Zodiac Deck, "Time to finish this."

Ryuki's emerald green eyes looked at her hatefully as he too revealed his Zodiac Deck, "I couldn't agree with you more."

Their Zodiac Belts were summoned and they slid the decks into them.

"EMPOWERMENT OF THE ZODIAC CAT/DRAGON! HENSHIN!"

Their armors encased them. Azula watched keenly as Mai smirked and Ty Lee looked completely astounded. Aang, Katara, Sokka and Toph watched (Toph can't exactly see with her eyes but you know what I mean) as two Zodiac Knights took the places of the opposing twins.

Draco's red eyepieces turned to his friends apologetically, "Gomenasai…" Copycat cracked her neck and drew a card before sliding it into her whip.

"Sword Vent!"

The Psycho Slasher appeared in her hands, the black sharp and spiky weapon held out and ready to draw blood. Draco activated a card as well.

"Sword Vent!"

The Dragon Flame Saber appeared in his hand. Both twins stared each other down before charging at one another.

Sparks flew as both weapons came into contact with one another.

CLANG!


Iroh looked up as the birds were flying in a panic. "Zuko, do you see that?" he pointed into the air.

"Just some birds flying, uncle. Come on, we need to keep moving," Zuko said.

"Birds do not simply fly in a panic. I think something is happening."

"Whatever, uncle…"

Zuko tightened the bag around his waist. Inside was an object he came to acquire and it was 'Finders Keepers, Losers Weepers'. He just wondered how much it would be worth in the next town if he decided to sell it.


Ant said, looking at the scanner, "I think I found something."

"Stop looking at that toy, Ant," Ryan said. "I'm feeling a very large amount of spirit pressure."

"And the Hyper Inzecter is right this way! We find it and we might just find the twins."

"And I say we follow my senses. I think there's a battle going on between two very powerful individuals."

Ant then thought he sensed something. He then agreed, "I think you're right. Let's go!"


Draco was pushed back against a tree by his sister's spiked sword. His own weapon lay on the ground and he grunted in pain as the spikes dug into his armor. Aang, Sokka, Katara and Toph were dealing with the three Fire Nation girls so they couldn't lend n assist.

"Your friends have abandoned you," Copycat continued to taunt as she pushed the spikes deeper into his armor. He winced. "All because you're just a Firebender. It seems that, like before, you've chosen the wrong-OOF!"

Draco hand was raised, smoke coming off it. He had blasted his sister back with a fireball. "Why don't you shut up?"

"Strike Vent!" Copycat's Feline Claws materialized and she slashed them at her brother.

"Guard Vent!" Draco's shields were activated and he blocked her vicious swipes with them before he sent the rocks at her. She sliced the rocks to pieces and went straight at him. He brought up a wall of stone in front of her and she crashed into it, her limbs spread out comically.

"Kuso!" she swore! She then looked up to see her brother coming down with a drop kick and she rolled out of the way.

"Add Vent!" Draco summoned Dragonzer and everyone became shocked as the red dragon flew in and roared.

"Everyone! Get out of here!" Draco shouted as Dragonzer distracted the Fire Nation girls and his sister. Aang blew the flying bison whistle and Appa landed before them with Momo sitting on its head. Aang, Sokka, Toph and Katara boarded the giant animal.

"Ryuki, come on!" Katara called out to her friend.

"I'll catch up with you later! JUST GO!" Draco yelled back. "NOW!'"

Aang took hold of the reins. "Yip yip!" he ordered and the flying bison went into the air, blasting the Fire Nation girls back with the force created by his ascent.

Copycat sneered, "Your friends have abandoned you."

Draco smirked. "Did they?"


Appa flew through the air while a few people were talking about what they'd discovered about Ryuki.

"I can't believe he lied to us! Why didn't he tell us he was a Firebender?" Sokka yelled up, arms in the air.

"Oh, I don't know.." Toph began sarcastically, "Maybe it had something to do with you hating the Fire Nation and Firebenders."

"I don't hate all of them," Sokka responded. "It's just that, well…"

"Remember your speech last night, Sokka? You told him how evil the Fire Nation was as well as most Firebenders. I guess he was afraid we might reject him," Katara reasoned.

"I guess that would make sense, huh?" Sokka rubbed the back of his head in embarrassment.

"He must think we've rejected him or something," Katara spoke sadly. "But we haven't. He's still our friend and he's covering for us right now! He needs our help."

"We have to turn back!" Aang said.

"There's no need to do that," a voice playfully said. They all turned to the direction of the voice and saw a red, black and silver armored individual flying next to them. He was riding upon Dragonzer the red dragon.

"RYUKI!" they all yelled out happily.

"You're okay!" Toph smiled. Draco then jumped off Dragonzer and his feet shot fire to allow him to fly over.

"You're flying!" Sokka said, seeing the flames shooting out of Draco's feet.

"Something I picked up," he spoke casually before he guided himself aboard Appa's saddle and his armor disappeared. Momo perched itself on his shoulder. "Hi, Momo-chan!" He then turned to his friends. "I guess you want an explanation, huh?"

Sokka placed a hand on his shoulder. "You don't owe us one. You had every reason to hide that fact about you. You're our friend. Sure you have some skeletons in the closet, who doesn't? But what matters is you did help us out."

"Arigatou, Sokka-san."

"And now Aang has a Firebending teacher, even if you are from another world," Katara said with smile.

"I might as well teach Avatar-sama, I mean Aang-san, to learn how to control fire. I just call it Firebending because it's easier to pronounce. Back home my fire powers are either called Combustion or Pyrokinesis."

"Pyro-what?" Toph questioned.

They all laughed.

"So, how did you give them the slip?" Sokka asked.

Ryuki smiled. "Well, what I did was…"


(Flashback)

Going up against Copycat and Azula wasn't easy. Their combined flame and electrical attacks were taking a toll on his body. Since Azula had lost the Avatar, she wanted to vent out upon a red clad Zodiac Knight.

"Remember, Azula-ojou-sama," Copycat reminded. "His head is mine."

"Fine with me." Azula agreed after a moment.

Draco drew a card and slid it into his gauntlet. He then created a smokescreen around him.

Ty Lee, Azula and Mai coughed. Copycat blew the smokescreen away with Airbending and then lunged forward, digging her claws into the chest of Draco. After all this time, she had finally done it. She had finally defeated…

Then her 'brother' shattered like glass.

It was a dupe! He had used Trick Vent!

She screamed.

(End Flashback)


Aang, Sokka, Toph and Katara laughed as did Ryuki.

"If I could only see the look on her face!" Sokka said as he wiped a tear out of his eye.

Ryuki looked down sadly. Katara went over to him. She opened her water skin. "Are you hurt?" she asked. "Let me heal you," she offered.

"Can you heal heartbreak?" Ryuki questioned.

"What's wrong?"

"I had to fight my own sister. The things she said hurt more than her strikes."

"I can't understand how someone like you can have a psycho like her for a sister!" Sokka spoke up.

"Bite your tongue!" Ryuki snapped. "She's my onee-chan, Sokka-san, and I don't appreciate if you speak of her in such a way!"

"Ryuki, she tried to kill you," Sokka reminded. "How can you-?" Toph grabbed his shoulder, making him stop.

"She wasn't always like that," Ryuki said. "She used to be someone I looked up to. I still believe the sister I love is still inside her, buried under all that hate and jealousy. Besides, you don't know her like I do and I still know and believe that there is still good in her."

Everyone kept silent, amazed at Ryuki's faith.

"And don't bother buying me new clothes. I already got it covered," Ryuki said as he pressed a button on his watch. A green ring of light swept over his body. Much to the shocked eyes of Aang, Katara and Sokka, Ryuki's jumpsuit was replaced by a green Chinese shirt and dirt brown pants. He also wore a pair of black sandals and his red hair had turned black.

"Woah," was their collective reaction.

"What?" Toph asked . "What happened?"

"How did you do that?" Sokka asked.

Ryuki pulled down his sleeve to reveal his SB-Watch. He explained, "All operatives come with this watch. It helps us to disguise ourselves. I don't know how the device works exactly but it does come in handy."

Everyone nodded in agreement.

"So, where to now?" Ryuki asked as he leapt from the saddle and landed on Dragonzer's back.


Kat was out of her armor and was in a foul mood and her foul mood matched Azula's. The fire princess had curtly excused herself sometime before and Mai and Ty Lee were just lying low and hoping they wouldn't be noticed.

'I'll get you, brother,' Kat swore in her mind. 'I'll get you even if I have to tear this entire world apart to find you!'


A/N: Any suggestions? Should the Avatar Gang meet Zuko and Iroh? What episode do you want to have Ryuki be in? What about 'The Library'? Maybe he can help against the Sandbenders?
