Thanny is 16 and the turtles are 18, if you guys want more stories of when she's little tell me.

A new is vigilante born.

It's a warm august evening and Thanny is outside buying some supplies in the shop, when she was younger she always had to do this by night because if she ran into trouble master Splinter or Leo could jump in and help her. Now she was allowed to go during the day, because it was safer then when it was dark and now she wasn't scared anymore and she could properly defend herself.

Tonight she quickly had to run to the shop because, they were out of pizza and she volunteered to go and buy some. For some reason the pizza boys where afraid of delivering pizza in the sewers.

She had 5 frozen pizza boxes in a bag and she was making her way to the manhole. She's wearing a green t-shirt and a pair of old jeans, in her pocket she had her shell-cell, Donny had developed a panic button for her, it was a little red button on the outside of her cell, when she'd be in trouble she had to push it, an alarm would go of in the lair and her location would appear on Donny's computer screen. Her brothers would come to her rescue, the one thing worse then 4 overprotective brothers are 4 overprotective teenage mutant ninja turtles as brothers.

She only had to use the button once, she was 14 years old and went to the shopping with April and they were pushed into an ally by 12 purple dragons, April and she were able to take out 6 but the others grabbed them from behind and pinned them to the ground. Her brothers were there quickly and weren't to pleased with her current situation, she almost felt sorry for the purple dragons, almost. She'd never seen them so angry, she was fine only a couple of cuts and bruises but nothing serious. But it took 3 months to convince them to let her out of the lair again and another 3 to let her go alone.

She reached the ally closets to the lair, she bend down to move the manhole cover, but someone, pushed her over and she fell into a puddle of mud. 'they are going to pay for that!'

"well what do we have here, a little girl all alone in an ally, it's my lucky night" it was only one guy, he was in his early thirties and drunk as hell, this wouldn't be too hard.

"I'm so going to enjoy this" she said and flipped back onto her feet, steadying herself in a fighting position.

"kitty has some spunk, I like that" he came closer. As fast as lightning she kicked him in the solar plexus and he fell with his back on the ground.

"stupid little…" he got up, picked up a metal pipe and charged her again. a little smirk appeared on her face.

"this is just to easy" he swung the pipe at her head, she ducked and with two fingers she poked his arm a couple of times, he cried out of pain and dropped the pipe.

"what did you do!"

"pressure points" she smirked, she turned around and kicked him in the face, he flew with his head against the wall and passed out.

"loser" she whipped her shirt of, took the pizzas and opened the manhole and jumped down.

she reached the lair without any further problems.

"hey guys, pizza's here" she called.

"coming" she heard Mikey yell from the living room.

"wait up Mike leave some for us" Donny yelled after him, Leo and Raph soon followed.

"go ahead guys I'm going to change"

"wait!" Leo yelled. "turn around"

"Leo there's nothing I'm just going to change my shirt ok?" she knew if they saw her shirt was filthy she had to tell about the guys who attacked her and she'd suffer the consequences.

She was about to continue but Raph and Donny blocked her way.

"what happened?" Donny asked.

"nothing I tripped, that's all"

"you tripped? Cut the crap Thanny" Raph said, crossed his arms and his look told 'tell us or I'll pound you'

"ok, ok no big deal, just a drunk who got a little to close for his own comfort"

"what?" they all yelled.

"why didn't you press the button?" Donny asked.

"it was just one guy"

"you can't know that, he could have had backup waiting across the corner"

"I'm not defenceless Leo, I tell you if he'll wake up in that ally with one serious head ache" she smirked.

"good job sis, did you use your famous xena-pressure-point attack?"

"yeah, it was so cool! He screamed and immediately dropped the metal pipe"

"he attacked you with a pipe? I'm going to kill him!" Raph said and walked to the exit.

"no Raph, guys come on, why do you think I'm defenceless? You don' act like this when one of you gets hurt, don't you trust me?"

"it's not that, Thanny …"

"then what? Raph, you think I'm weak, don't you? newsflash I'm not your weak little sister you have to protect all the time! I can take care of myself"

"we don't think you are weak Thanny, we're just worried about you" Donny said.

"I appreciated that, really but I'm a ninja too and I can take care of myself alright"

"alright, but next time, if something like this happens, would you please press the button? Just to make us feel better" Leo asked.

"if that makes you feel better, I'll press the stupid button"

"thank you" Raph pushed her asides and sat in the couch.

"now Mikey would you please warm up my pizza while I go change?"

"sure thing sis"

she went quickly upstairs to her room, put on another t-shirt and tied her green bandana around her head. And rushed downstairs again, tonight was one of their weekly movie-nights.

She got out of her room and found Leo and Raph fighting on which movie they were going to watch.

It was either a horror movie or an action movie, Donny preferred science fiction and Mikey adventure and animation, she liked romantic movies but she wasn't allowed to watch those at a movie night with boys.

Is was an action movie and after that a horror flick.

She placed herself on her favourite spot on the floor with her back she leaned against the couch where Leo and Donny lied. Raph sat left of her and Mikey jumped into the other chair with the pizza plates in his hands.

"pizza's served" he carefully placed the plates on the table. "which movie are we going to see?"

"batman's beginning" Leo said.

"you picked the movie, I thought you weren't a fan of superhero movies" Thanny asked.

"true but it says on the cover that there are ninjas in the movie and I thought a movie about vigilantes and ninjas couldn't be a bad one"

"cool choice bro, cross over to the comic side"

"shut it Mike" Raph threw a pillow at his head.

"hey watch the pizza"

"baby" Thanny replied.

After the third movie Donny and Thanny were asleep, and after the fourth Mikey joined them, in the middle of the fifth Leo and Raph also surrendered.

Master Splinter was up at 6 am and saw the tv still on, he went to shut it off and saw his children asleep. Donny and Leo laid half on the couch, Mikey was snoring a bit and Thanny and Raph leaned on each other. They looked so peacefully and cute he had found them often in this similar position.

Just one more hour of peace he thought. he went to the kitchen and made himself a cup of tea. He had heard the argument, yesterday. He knew how his sons felt, they tried to protect their little sister and shield her from the cruel world above, like he tried to do for a long time but he learned to trust his children and in their abilities to defend themselves.

Yet that didn't mean he didn't worry every time they went out on patrol or every time Theng Sjen went to the surface, when she was little he used to push her harder and harder through her training, sometimes harder then when his sons. She had to learn how to defend herself, he couldn't bare to lose someone close to him again.

7 am came sooner then it seemed and 5 alarm clocks went off, brutally awakening the sleeping teens.

Leonardo got up without trouble and went into the dojo for a warming up. Donny and Raph followed, only his two youngest seemed to have the much trouble getting up.

"if you two are not in time for morning practise, you owe me 50 flips." Splinter said when he passed them.

"coming, coming" Mikey said and got up, pulled up his little sister and dragged her to the dojo.

"I'm awake, I'm awake"

"let's see how awake you really are, Michelangelo spar against Donatello, Leonardo continue to do your kata's and Raphaël you go against Theng Sjen"

"oh boy"

"ha, come on princess, I'll go easy on ya"

"pss, please I'll go easy on you, you wuss"

When Master Splinter had thought her how to win a fight by using pressure points she had to swear to him, not to use those techniques on her brothers. She of course obeyed her master definitely after seeing the effects of them yesterday.

Raph started the fight with a kick to her head, she ducked and tried to kick his legs from under him in the process. Of course he saw this coming and jumped, in his turned he brought his leg down fast, Thanny quickly did a back flip and avoided the kick, now she balanced on her hands, she twisted her body around and threw her legs at her older brother. He ducked the first one but caught the second one, thinking he hand her now he smirked a bit. But Thanny pushed of on the floor and used Raph as leverage to flip over him, because of this move she had twisted her leg out of his grasp and landed behind him.

Again she tried to kick his legs from under him again and this time it worked. He landed with a loud thud on the bamboo floor. But used his hands to flip himself back on his feet again.

"I have to admit that's a nice move, but it's gonna take a lot more that gymnastics to keep me down, princess" he said and smirked evilly at her.

"bring it on wuss" she called back and fell into her fighting stand again.

This time she charged first. She tried to punch him a couple of times and even though she moved a lot faster then her brothers, he easily caught both her fists and twisted them so she was forced with her knees on the ground.

"give up princess?"

she looked up at him and smirked, she rolled on her back and pushed Raph away from her with her feet. Now they were both on the floor. Donny, Mikey and Leo were finished already and were watching the scene.

"I bet that Thanny's going to win" Mikey said to his brothers.

"you're so on bro" Donny said.

"I don't know Donny she seems really determent today" Leo said.

Thanny and Raph flipped back onto their feet equally, and were panting heavily now. Now they both charged at each other, Raph punched at her, she blocked it, he punched three times more, every time she blocked it perfectly. But the fourth time she slipped up and he hit her right in the face. She fell back onto the floor from the force, but got as quickly back on her feet. She took out her weapons, which were two large kunai knives, Raph smirked at took out his much bigger sais.

They charged again, full speed until their weapons made contact, with a loud clang! They pushed each other away, of course Raph had more physical strength then her so she almost got pushed of her feet but she quickly recovered. But not quick enough Raph jumped up and prepared for a full force attack. She rolled out of the way and twisted her kunai in her hand, it was her turn to attack now. she tried to hit him with one kunai but he blocked it and tried to attack her with his other sai, she also blocked him. Their weapons were entangled in each other. Thanny pulled herself up and was about to kick her brother in the chest but he bent over and she flew over him, but she pushed her feet down quickly on his plastron so he fell on the ground with her standing on top of him

Donny threw Mikey a coin, he'd lost the bet.

"give up already?"

He angrily looked at her and with his last power he pushed her foot of his is chest so she fell next to him.

"I give" they said at the same time.

"good job my students, you are dismissed"

Raph got to his feet and held out his hand for his sister, she grabbed it and he pulled her up.

"thanks bro, good fight"

"yeah I know"

"hey Thanny you alright? That was a nasty punch"

"I'm fine Mike" she patted his shoulder and went to the bathroom for a long warm shower.

That evening:

"master we're going on patrol" Leo yelled.

"alright my sons be safe" and he went into his room to meditate or to get some sleep.

"wait!" they turned around to see Thanny rushing at them with her entire gear on.

"no, you're not going with us" Leo said.

"what? Why not? You could go on patrol when you were 15! I'm 16, why can't go with you?"

"it's dangerous Thanny you could get hurt" Donny said.

"yeah so you too"

"that's different, we can't watch yer back the entire time" Raph came closer to her "it'd be better for all of us if ya just stayed here"

"you don't think I can handle myself? We're a team! I want to help, please you know I can do it, I can look after myself!"

"sorry Thanny" Leo turned around again.

"Mikey help me, tell them I can do it" Mikey was the only brother who she thought that believed she could fight, but the others angrily looked down at him their eyes had the if-you-say-anything-we'll-kill-you look.

"just listen to Leo dudette, maybe another time" they turned around and walked out of the lair leaving their disappointed sister behind.

"they don't believe in me, they never did" she ran to the dojo and punched the punching bag until her knuckles started to bleed, but she continued, biting back her tears, she felt betrayed, stabbed in the back. Worst of all she couldn't stay mad at them, she had to forgive them, because if she confronted them with this, with how she felt they'd just tell her the same thing over and over again. and she couldn't take that, not now not ever.

Her own family didn't believe in her, she had to prove that she was strong and could take after herself, not to prove her brothers that they were wrong but to prove herself that she was right. After an half hour of crying and punching she retreated to the couch and turned on the tv.

…Yesterday evening a couple of vigilantes in Brooklyn stopped an armoured attack in a jewellery store…

she didn't even hear the rest of the newsflash, she got an idea. If Casey could do it, anyone could do it definitely her, she'd become a vigilante! That was the way of proving herself she wasn't weak as her brothers made her feel, the way of helping her brothers and becoming a closer part of the family.

But how is she going to do this? She knew she couldn't just walk out of the lair without anyone noticing, no she had to think of a clever plan to outsmart, Leo, her brothers and master Splinter. It didn't feel good, lying to them like that but desperate times call for desperate measures, she's been on the sidelines for 16 years now it was her time to play.
