Ch. 1

"Major Changes"

Years after their father Hamato Yoshi's death the four brothers were all bent on Vengeance of the one responsible for their Father/Sensei's demise. Leonardo the eldest who sported a blue bandanna with his katana in a harness that went across his muscular plastron; was about to turn 25 and was training in the dojo with more anger than usual. His brothers watched and knew if he ever encountered the one that cut down their beloved father the outcome would not be a good one. Leonardo was known as a very deadly ninja when his family is messed with. Some of his past enemies seen how deadly a very young 18 ½ year old could be when he warned a former enemy if she messed with his family again she wouldn't be so lucky.

Michelangelo carefully tapped Leonardo on his shell.

"Leo are you training for another mission again? I can't believe my elder brother is some kind of agent for an organization that consists of highly skilled ninjas."

Leonardo sheathed his katana and looked at his curious baby brother in his baby blue eyes.

"Not right now I am not; just my normal training in case I do get called to duty. Shouldn't you and Raphael be going to the dojo for a class in less than 30 minutes. Raphael growled at their baby brother.

"Let's go Mikey see ya lata fearless and Brainiac."

When the two brothers left Donatello looked at the eldest.

"You know Leo; it's unbelievable on how two mutant turtles like ourselves can be a part of an organization headed by two of our former enemies. You have so many scars from the many missions you and your um partner have been through. Does she know what you are yet?"

He looked at his brother with a slight glare.

"No Don; for almost four years I have hidden the identity of what I really am. If she ever found out what I am she might just ask for a new partner. So I rather not reveal myself to her."

Donatello shook his head.

"You really are something else bro. While you practice I'll be getting over to headquarters April has a new person coming in to assist me since she will be going on maternity leave soon and not able to work. Besides; don't you have an um meeting with Kemeko today?"

Leonardo looked.

"Oh shit I almost forgot she's gonna kill me. If anything comes up, you know how to reach me."

Donatello just chuckled.

"Same old Leo just more deadly."

He entered his room in their two story house and got ready to meet Kemeko. As he exited the house with his blue long-sleeve shirt; black jeans, and his Jordans he made his way toward the pizza parlor where he was to meet Kemeko. She looked up with her arms crossed.

"You're late Leo; and once again covered. What is with you I swear. We have worked together for nearly four years and not once have I seen your face or your body."

He sighed.

"Kemeko can we please not argue about this right now."

Kemeko is a 23 ½ Lethal ninja like her partner Leonardo. She has long black hair with purple ombre in a half ponytail today. They ordered and she turned to him.

"It's your turn to pay Leo; I did last week."

He just shook his head as the waiter brought them their pepperoni pizza slices with their Pepsis. She looked up and tried to get his attention.

"Leo what are you looking at? Oh I swear you are impossible sometimes. Well anyway I just got the call today on our next mission my little sister Mirasumi will be accompanying us. She just passed her last test and is at the same level as we are. "

He sighed.

"Are you kidding me; we have to drag your little sister along on our missions where we go and hope she doesn't get lost."

Mirasumi came up behind him and slapped him.

"That was just rude; I am not a child! Oh by the way one of your brothers has been teaching me some moves."

He looked up and nearly spit out his pizza.

"What brother?"

She looked and thought.

"Oh the one always in orange."

He paused for a second and excused himself.

"Umm Kem and Mira I'll be right back need to make a phone call."

He leaves in a rush and dials his baby brother's shell cell while Michelangelo and Raphael were in the middle of a lesson. Raphael glared when he heard his shell cell rang. He looked and smiled slyly.

"Sumbody is in trouble; what ya do this time Mikey."

Michelangelo gulped when he saw his elder brother's name and answers acting like an answering machine.

"Sorry Michelangelo is not here at the moment please leave your name and number and I'll get back to you dude or dudette. Beep." And he hangs up.

Raphael looked at his baby brother and bowed to his class.

"Ten minutes of sparring and Kisumu no using your weapon right now. Begin now! Mikey to the back now move it!"

Michelangelo gulped and tried to run away from him. Raphael grabbed him.

"What the hell did you do now! Leo knows we are in the middle of a damn lesson! Answer me Mikey."

Michelangelo gulped as he responded to his elder brother glaring at him.

"I kind of taught Mirasumi some moves."

Raphael just shook his head.

"Always getting' in trouble aren't we?"

Raphael turned to his class and they all kneeled as he demonstrated the lesson for the day. He wore a black Gi with Long Sleeves and always had his face covered. The smart alic of the class looked up and interrupted.

"Sensei Hamato; why don't you ever reveal yourself to us your students?"

He paused and glared at her.

"Kisumu come forward and stand before me. If you can defeat me in battle, then I will reveal myself if you fail then my appearance stays as is. Understood!"

His class sits and watches as Kisumu approaches their sensei Raphael Hamato. She looked and asked.

"Sensei can I use my weapon?"

He shook his head and glared.

"No you can't you need to defeat me in hand to hand combat."

The class watched as they fought and looked in awe as their fellow student was fighting against their Sensei who is a very skilled ninja master like his father Hamato Yoshi. They all stared as Kisumu was able to knock their sensei to the floor. She looked and stared.

"I beat you Sensei Hamato; now you need to reveal yourself to us. It's not right for us not to know our Sensei's face."

Michelangelo stayed silent and looked at him and face palmed.

"Nice going Master Hamato beat by a girl; now you have no choice but to reveal yourself to your students."

Raphael flipped back up on his feet and looked at his students as he removed the cloth from his face. He then replaced his red bandanna and looked up. Kisumu just looked and bowed to him; and she kneeled with the rest of her class.

"So you're a 6-foot mutant turtle? Why were you hiding yourself; weren't you one of the four that saved our city?"

Michelangelo looked and also removed the cloth from his face.

"Yes we are; now all of you back in position as the lesson continues. Bro you can continue the lesson now."

Raphael continued the lesson and was a little relieved he no longer had to hide his identity.

~At Kahn's Dojo~

Karai entered and looked at Kahn.

"What is the meaning of this Kahn? You are the new leader of the foot. Why have you summoned me?" She demanded as her husband just sighed.

He smiled slyly as he sat at his desk with his hands crossed.

"You're the only who was able to find the turtles and I want your help to end their pathetic lives."

She glared at him.

"I no longer have anything to do with my father's dishonorable foot clan. Also my life was spared and I refuse to break the alliance with Leonardo and his family. You are a fool and will lose your life because of your foolishness. Sayonara Kahn!"

He laughed evilly as she turned toward the door of his office.

"We'll see if you change your mind Karai. Enjoy your happiness while you can Karai."

As she and Chaplin exited Kahn's dojo they were greeted by a beautiful five-year-old girl from their limo.

"Mommy who is that man you and daddy were talking to? He seems like a big meanie."

She smiled and held her close.

"Nobody you need to worry about our precious Kazue."

Kahn spotted the child and called Hun. Hun was sitting at his desk when he answered.

'Hun here; no I am not the head of the purple dragons anymore Kahn. Now lose my number! After I tell you the new leader of the Purple Dragons you better lose my number. His name is the Shark. Goodbye Kahn!'

His son Ryu; looked at his father and asked.

"Does that mean you are an ally to the turtles too like Karai?"

Hun looked at his watch and turned to his son.

"Come on to bed now Ryu. Daddy has a very important call to make."

After he put his son to bed he dialed the Bishop Stockman Invisible Alliance and Stockman answered.

'Hun long time no talk since Bishop and Donatello reversed the mutagen to turn you human again. Why are you calling?'

He responded.

'I have some news that your agency may want to take in consideration Stockman. It concerns Karai's daughter and Kahn's plan to kidnap her to force Karai to break her alliance with those freaks. I need to inform Bishop immediately can you connect me to his office?'

Stockman responded as he put the call on hold and paged Donatello.

'Don there is an urgent call on hold for Bishop can you please tell him I am working on some new technology for our agency.'

Donatello knocked on Bishop's office door and heard his voice.

"Donatello take the call; I am in the middle of a breakthrough with some of our top agents. Also you and Nuriu go through the schematics of the program we found when your father was found brutally murdered in his old dojo after the flames were extinguished."

He sighed.

"Very well Bishop. I'll give you the details after they are revealed to me."

He picked up the phone and tapped Nuriu.

"As I get the details write them down so we can give them to Bishop so he can send in our top agents."

Donatello answered.

'Agent Don here.'

Hun spoke in his phone.

'A freak; can you please connect me to Bishop.'

Donatello gritted his teeth.

'He is busy at the moment Hun; do you ever get tired of calling us freaks? You forget who turned you back to your annoying self.'

Hun yelled.

'You are the ones who turned me into that disgusting turtle in the first place.'

Donatello argued with him.

'First of all it wasn't us it was our other world that turned you into the turtle Hun. Off that subject why did you call?'

Hun took a deep breath as he responded.

'Kahn is back and his target is Karai and Chaplin's daughter. They are planning on abducting her after school tomorrow.'

Donatello shook his head and sighed as he hit the red button. All the agents rushed to the lobby. Bishop and Baxter came down the elevator.

"What's the emergency Dr. Hamato?"

Donatello spoke as Nuriu handed Bishop the information Hun gave Donatello.

"Karai's daughter is in danger; Kahn and the purple dragons are going to abduct her after school tomorrow."

Bishop shook his head as he called Karai.

~Saki Mansion~

Chaplin answered the phone and his heart sunk as he listened before he responded.

'Chaplin here; Karai is asleep right now she wasn't feeling well. Kazue in danger; how did they even find out we have a five-year-old daughter? Make sure your top agents are on this mission Bishop as you are aware the foot and the purple dragons have an alliance and are more deadly than they once were. Yes, we will be there tomorrow; I'll tell my wife in the morning. Chaplin out.'

He shook his head as he hung up the phone and kissed their five-year-old princess on her forehead as she slept. Then he headed upstairs to their room and got in bed next to his wife who was fast asleep.

~The next day~

Donatello woke up early and exited his room smelling coffee already brewing. He entered the kitchen to see his elder brother up already. Leonardo approached him and handed Donatello his coffee as he sipped his.

"So what agents has he sent in for a mission you won't tell me about and to remain on standby in case it's a failed mission? Well Don?"

He looked as he took his coffee to go and exited their house with no words.

Raphael was the next one up and snickered.

"So the top agent in the agency is kept in da dark! Maybe there are higher ranked agents than you Fearless! If this mission is so big why aren't you involved? Well!"

Leonardo glared at him.

"It's not my damn fault that you refused to join Raph! I have explained it to you a million friggin' times why Donatello and I are part of it. So stop asking me stupid questions that I can't answer. Now drop it already; I'll be in my room meditating in my room so I don't end up kicking your damn shell in now move!"

Michelangelo entered cautiously as Leonardo made his way up to his room.

"Leo can I still join?"

Raphael chuckled.

"Really Mikey; you aren't skilled enough to join. So give it up already!"

Michelangelo got angry and lunged at Raphael kicking him into the dojo wall.

"I'm tired of you putting me down! I'm not the one that got my shell kicked by one of my female students forcing me to reveal myself to my entire class! So don't go there dude! I am going to join so I can be with my brothers. You be stubborn all you want! Not this turtle; I want answers to who killed our damn father and want to use my ninja skills again!"

Leonardo face palmed.

"You have a lot of tests to take Mikey; you won't be at the same level as I am. But you're going to have to wait until this major operation blows over before you talk to Bishop. Looks like you knocked out the hot head and finally shut him up; for that I thank you."

Raphael came to and flipped back on his feet and entered his room slamming his bedroom door. Michelangelo looked at his elder brother sipping his coffee.

"Did I mention the student that defeated our brother is umm your partner's best friend Kisumu who happens to be Donatello's assistant's older sister?"

Leonardo spit out his coffee.

"No you forgot to mention that small detail Mikey! Oh shit if she tells Kemeko then I am dead! She hates liars and has a very deadly temper when she gets angry."

Michelangelo looked at him.

"Reminds me of a certain older brother; Leo. Oh also she is now Raphael's top student and will be having private lessons with him."

Leonardo buried his head in his hands.

"Why is this happening to me?"

Michelangelo shrugged.

"Beats me bro; I'll be in the game room working on my high score."

~Back at Bishop Stockman Invisibility Alliance~

Donatello was working on a new form of defense as Bishop paced back and forth.

"Why hasn't anyone checked in yet? What is going on? Nuriu get the agents in the field to answer me now."

She tried frantically to get them to answer and got nothing but static!

"Sir none of them are responding. All I am getting is static. I think we need to call in the Dragons and the Wolf!"

Donatello looked at his computer and shook his head.

"I have no visual at all. Nuriu might be right let's call in the Dragons and The Wolf."

Karai and Chaplin stood in silence as her cell went off. Bishop signaled Donatello to connect to get a signal of the call. Then he looked at Karai saying in a whisper.

"Pick up so we can track the signal. Don't let he or she hang up too quickly."

She answered.

"Yes this is she. Can I help you!"

On the other end a raspy voice.

'Mrs. Chaplin the only way to save your precious Kazue is to break your alliance with the brothers! You have one week to abide or little Kazue won't live to see her sixth birthday. Just in case you think I am bluffing there is someone here that wants to speak with you.'

Karai heard her precious daughter's voice so scared calling.

"Mommy and Daddy I don't like this dark place; I'm scared. Help Me."

Then the phone went dead and she broke down in tears on her husband and her older sister. Donatello saw the pain in her eyes and shook his head.

"The capturer hung up too fast; I couldn't track it. I have no idea where to begin. Poor Kazue."

Bishop picked up his cell and dialed Leonardo. Leonardo was at the pizza parlor with his partners when his cell rang. He answered as he was about to pay the bill.

'Blue Dragon here; what happened? Yes, they are both here with me. Very well Bishop we'll get down to the bottom of it. We'll be there pronto. Blue Dragon out.'

As he hung up his cell.

"Obviously the matter just became more grave! Bishop wants us at headquarters pronto. Let's go. Yes, Kemeko we'll stop at your place so you can get ready. No I am not answering that question. Will you both please get off my shell about why I am always covered up! We have a mission and right now is not the time for those kinds of questions."

Kemeko looked at him suspiciously.

"Did you just say shell Leo? You know partners aren't supposed to have secrets Leonardo!"

He sighed.

"I said hell; and there are no secrets between us Kemeko. Let's move fast. Drop it both of you please!"

They made their way toward Kemeko and Mirasumi's house. Leonardo sat in the living room while his two partners made their way up to their rooms and got ready. He sighed and shook his head.

'Sooner or later they are going to find out Leo; one day you are going to have to reveal to them what you really are. Kemeko is right partners shouldn't have secrets between each other and you are hiding your identity from your partner of nearly four years.'

He shook himself from his thoughts when he heard Kemeko's voice behind him.

"Oh Leo look I just received my new ninja outfit from Stockman. What do you think?"

He looked behind and he just froze as he stared at her skin tight black; long sleeve shirt, and her purple pants; and black leather boots with her twin katana on her back with the purple bottoms. He swallowed hard and ran to the kitchen and gulped down a tall glass of ice water shaking his head.

'Oh man your brothers are right you have fallen for your partner Leo. You have fallen hard. Whoa back up shake that thought from your head you can't mix personal matters with your missions.'

He pulled himself together and they made their way toward headquarters. When they arrived Donatello tapped Leonardo.

"Bro here is your new ninja outfit; go change and then all three of you report to Bishop's office. Are you actually sweating?"

Leonardo looked and turned to the two girls.

"Go in Bishop's office while I get suited up and tell him I'll be right there."

"No I am not Don; we are cold-blooded what's the matter with you? Speak for yourself; you have sweat dripping down and your assistant is blushing too. So don't go talking."

He entered the men's bathroom and put on his ninja outfit complete with a blue hood to hide his face with long sleeves to cover his green skin. His pants reached down to his ankles and he slid on his black boots….and he slid his katana into his new harness and smiled in the mirror.

'Looking good Blue Dragon; now to start the mission.'

He exited the bathroom and entered Bishop's office and drew his katana. Bishop yelled.

"Swords down Dragon; now calm yourself and listen. I mean it!"

Chaplin looked at him as Lotus held a crying Karai in her arms.

"We have an alliance with you Leonardo; we are not about to break it. But we do need your expertise and of course your partners' as well. Our 5-year-old daughter Kazue was abducted after school today and we have a week to abide by their demands. The capturer is threatening to kill our little girl if we don't break our alliance with you!"

Leonardo looked at Karai and saw the tears falling.

"So you did heed my warning Karai at our last encounter. I can see that you and Lotus are acquaintances what a small world this is."

Lotus looked up and spoke.

"Actually no; we are sisters I am her older sister. Since when do you?"

He signaled her and pointed to his two partners. Then Lotus looked.

"Oh I see. The only problem is we have no leads on where they have my niece. Also the agents that were called in never checked in so there is no telling what happened with them. One lead we do have is that the Purple Dragons have an alliance with Kahn and the new and improved foot clan."

Leonardo thought for a second.

"I know exactly where to get my lead. Let's go ladies clock is ticking. Karai I swear on my honor no harm will come to your daughter. Kemeko and Mirasumi let's go first stop Purple Dragon former leader to find out who the new one in charge is. Find him and then we can start a lead on Kazue's whereabouts."

Stockman stopped all three.

"Take these and use them wisely; they may help assist you where katana fail to succeed. Good luck Blue Dragon, White Dragon, and Golden Wolf. Make sure you try not to lose communication with us. Also this may get you to your destination faster."

Mirasumi saw Stockman throw Leonardo a set of car keys and her eyes widened when she saw the car.

"Aww Sweet ninjas riding in style! I love being level 550 with you guys."

Leonardo popped the trunk and got in the drivers' side as Kemeko got in the passenger seat.
