Chapter One: Mutation Day

Walking through New York City, fourteen year old Lucky Hamato bounced down the streets, a fifteen year old redhead finishing a survey for school.

"Your favorite color?"

"Green."

"Favorite hobby?"

"Skateboarding."

"Really? I never see you."

"I usually skate with my brothers."

"Ah, the mysterious older brothers. That explains a lot."

"What do you mean April?"

"Well, you put pass for favorite clothing store, a lot of these answers match up with other boys who took the survey, and I never met a girl who wears hand-me-down boy clothes." Lucky tugged at her plaid button up shirt, three sizes too big.

"April, sometimes there's more to someone then what you see, or what a survey tells you." She waved a black and white fan in front of her face. April laughed.

"Thanks for your help Lucky! See you tomorrow!" The two girls went their separate ways, and when April O'Neil was far enough away, Lucky moved a sewer cap and jumped down inside, her skateboard waiting for her. She tied a black mask around her head, one similar to her brothers, and started to shred pipe.

Lucky skated down to the lair, thinking about her 'brothers'. It's been fourteen years since Master Splinter found her abandoned in the sewers, only months old.

Michelangelo was the one who named her. Leonardo helped teach her the basics of fighting. Raphael taught her trash talk and how to take care of pets, like Spike. Donatello taught her all she needed to know for school. And Sensei was the best father ever. What other father teaches his daughter Ninjutsu and gives her a weapon? Sure, her fan didn't look like much, but if she wanted she could do real damage with it. Today was a real special day for her family, and she had something real special for them in a bag.

After all, it was mutation day. And what was mutation day without a cake?

She managed to sneak the cake in the fridge while the others were practicing. She tossed her school bag down and went to join them.

"Lucky!" Leo stopped fighting to greet her.

"Hey Lady Luck." Raph stood in mid attack, not wanting to miss a chance to tease his little sister or hit his brother.

"How was school Lucky?" Donnie always seemed more concerned about Lucky's school progress than Lucky was, probably because he was.

"Hey sis, how's it hanging?" Mikey smiled up at her, unconcerned about losing since he had Luck to back him up.

"Leo! Hey, Raphie. Good,Teacher Don. Same as always, bro." She bowed respectfully to Splinter. He looked at her with pride. She wasn't exactly Miwa's replacement, but possibly an adopted sister that his beloved Tang Shen would have agreed to. That was his thinking, fourteen long years ago. Now that little baby had grown to be a special part of his life, just like his sons.

"Lucky." He said happily to his blonde human daughter. She looked up at him with her bright blue eyes, like the sky attached itself to her.

"Yes, Sensei?"

"Which of your brothers would you like to spar with after this exercise?"

"The one who wins, and by the look of things it'll either be Raphael or Leonardo."

"I see. Would you not rather spare against Michelangelo or Donatello?" They had this conversation all the time and she would somehow always end up agreeing to fighting Mikey or Donnie.

"Sensei, I can handle myself against both Donnie and Mikey at the same time. I think it's time I try my luck against either Raphael or Leonardo." Splinter thought about this as they watched Raph take down Leo.

"Perhaps… You are right, my daughter. Raphael! Now you must try your best against Lucky."

"Seriously Sensei? Alright Luckily, just don't cry when you lose." Raph flailed his Sais, while Lucky waved her Tessen tauntingly at him. This was what they were both best at: Hand-to-hand combat.

"Hajime, begin!" Raph wasted no time to attack. Lucky blocked, flipped over him, and tripped him. He got back up, trying to hit her again and again, but she evaded, truly mastered as a kunoichi. She used Raph's strength against him, saving her own strength for real attacks, not rage attacks. Finally, Raph tired himself out and fell on the floor. Lucky laughed, getting high fives from everyone.

"Our little sister just kicked Raph's shell!" Mikey yelled in victory.

"Huh? What?" Raph rolled over, half awake, but still dazed.

"Yes. It seems I underestimated your training, Lucky." Splinter said as he walked over to her, holding something behind his back. "I think it's time we make it official." He handed her a Tanto. "Now it's official. You're a kunoichi, and I expect you to use your knowledge wisely, my daughter."

"I will, father." Lucky said. She looked at her Tanto, happy as could be. "So now I'm in the same league as my brothers?"

"Ninjutsu is not a contest, Lucky. However, you have Raphael's strength, Leonardo's determination, Donatello's thirst of knowledge, and Michelangelo's… enthusiasm. You are part of them. It's what makes us all all family, and you five all possess unique traits that make you siblings. That's enough training today. Hajime!"

"Hai Sensei!" The five said in unison. They smiled at each other. They weren't ashamed that they were always called family. Human, mutant turtles, half man half rat, it didn't matter. They were brothers and sister and Sensei. And not one of them would change a thing. Well, maybe Splinter would change his own past if he could, and Mikey would just to fit in and Donnie so he could go to school, but other then that, not a thing.

Lucky didn't know life any differently than this. She just knew to keep her family as secret as possible and tell her brothers what it was like above the sewers.

Later, when Mikey prepared them all algae and worms for dinner, they celebrated the Turtles and Splinter's Mutation day. Lucky and everyone else knew the story by heart, but Mikey wanted to hear it again. So Splinter told it again as they ate the cake Lucky brought home. And like every year, Leo asked if they were old enough to go to the surface. Lucky reassured them constantly they weren't missing much. But they wanted to see themselves. Splinter reluctantly agreed. Lucky even talked her way into going with them. 'To keep them out of trouble' she put it. They promised there would be no trouble. But she knew her brothers. Even if they didn't want trouble, they would find it. Raph especially. Mikey by accident, probably trying to make a friend. But as she dressed in her black and green kunoichi outfit and made sure her Tanto was belted on right and her tessen was hidden from view, she never imagined what kind of trouble they were getting into. She only thought "I look so awesome. I wish April was here to take a picture." Too bad April was out with her dad tonight and couldn't know her family consisted of mutants anyway. That was the only downside she saw with her life. Other then that she was certain she was living a dream and truly felt 'Lucky'.
