Emma's head was throbbing from the headache pounding in her head, she groans trying to pick herself up from the heavy ground

Suddenly she heard a voice that made her skin crawl

"Well look who's finally here."

Emma looks up to see another her

She was the same weight and height as her, her hair was braided into two big braids going down her back with blood red eyes glaring at her as she smiles a wicked smile showing her two sharp canine fangs.

Emma slowly backs away wide eyed at her evil looking doppelgänger scared "W-Who are you?"

"A spawn of evil."

"A sample of hell."

"A devil on your shoulder."

She starts to stomp towards Emma who backs up in a corner, she leans in close with glowing demonic eyes

"But you can call me Chaos."

..........................................

"Emma?! Emma?!?" Leo gets down on his knees trying to look inside the hole that Emma fell though trying to see if he can spot her but of course that mission was a mission failed.

"Hey Leo a little help here!!" Raph snaps him out of launching onto Kraang with his sias but gets punched in the face by Kraang's metal fist.

"Yeah we can get her when we're done stopping the machine." Donnie calls out finally getting a chance to get to the controls.

Leo nods still frantic on getting their little sister from inside the machine he runs up towards Kraang holding onto him with Mikey and Raph.

"Okay. About ninety seconds before this thing is complete," he said, mostly to himself. "All you, Donnie. No pressure, no pressure, no pressure."

..........................................

"W-What do you want from me?" Emma chews her sleeve shaking at Chaos who snickers mockingly squishing her cheeks tilting her head to the side "Hehehe aww is the wittle baby gonna pee herself?"

Emma whimpers a bit flinching as Chaos slams her fist into the wall denting it with a big hole

"Relax I'm not gonna hurt you I just want one teeny tiny little thing."

"W-What?"

"I want you and I to work together now that grander butt is out of the picture."

Emma blinks at her evil twin confused "Wait what?" Chaos gestures to something behind her, skeptical Emma walks over to the big shadow her eyes grow wide as she sees the giant icicle of Shredder in front of her. She brushes her fingers on his legs and of course he doesn't move, Chaos smirks leaning on Emma's shoulder "He's nothing but a stink icicle now which leaves room for us to bring this world down to its knees."

"No that's wrong!" Emma frowns snatching away from her.

"Oh come on scaredy-cat you saw how those people looked at you and your brothers. They're disgusted by you! You may think they'll accept you but they never will! Not the world! Not those stupid humans! Not even that so called family of yours!!" Chaos growls grabbing Emma by her collar getting into her face with a cold stare

"That's not true! My family loves me! You're lying!!" Emma yells with tears in her eyes covering her ears.

"You really think those turtles love you?" Chaos raises an eyebrow before letting out a wicked laugh "Hahahhaha!! Oh my god you're stupider than I thought you were!! They just helped you cause they pitied you!"

"You're nothing but a scared baby thumb sucking freak without me!! We were made to cause destruction and Chaos, those dumb humans need to pay!! And we can do it together!!" She smiles evilly leaning into Emma's ear making her shrink as she whispers in her ear.

"You know you're a monster."

"No one will ever loved you."

Emma shakes a bit puffing her cheeks grabbing Chaos's wrist almost breaking it making Chaos look at her a bit in shock as Emma glared her bright blueish green eyes as blood pours from her nose "No!!"

"You're wrong the world!"

"You're wrong about my family!!"

"And you're wrong about me!!"

"And I will not let you hurt ANYBODY!!" Emma swiftly throws Chaos against the wall slamming her back hard as she slides down the wall slumping over, Chaos smirks wiping the blood from her nose away with her thumb standing up cracking her neck with wide eyes squinting at Emma.  "So ya wanna do it the hard way huh?"

Chaos's red eyes glow as the knifes from Shredder's armor melt and levitate into the air surrounding Chaos who smiles evilly at Emma.

"We can do it the hard way."

..........................................

Meanwhile, Emma's brothers had their hands full, keeping Kraang's attention on them. "You know, I'm looking forward to enslaving you," he sneered at them. Kraang turns towards Donnie and the turtles took off after him.

Mikey wrapped himself around the suit's feet while the others tried to slow him down by pulling on his robotic limbs. "A cage for the tortoises might be nice." As Leo was thrown away, Raph growled as he pushed off Mikey's shell and stabbed his twin sai into the suit. "We're turtles, not tortoises! There's a big difference."

"Yeah," Leo agreed as Raph was thrown off. "Turtles bite!" He jumped up and slashed the blades of his katana through the robotic hand heading straight for Donnie, severing it from the robot suit.

Krang merely laughed. "You don't think I've got spares for this?" he taunted. He waved his robotic hand and things rose up from the platform around them, causing Raph to dodge out of the way as a blue beam shot towards them, and something flew towards Krang.

"Guys, he is literally rearming," Mikey said,

Leo charged at Krang and jumped on his back. He latched onto an arm as Krang began spinning around, and at the same time Raph, Mikey jumped on as well, trying to hold on as the world went by in a blur.

"Donnie!" Leo called.

"Just give me ten seconds," he called back.

Meanwhile, Krang was spinning even faster and it was getting harder to hold on, and all of them were feeling a bit dizzy by this point. "Guys? I don't think I'm tall enough to ride this ride!" Mikey groaned, his hold slipping.

"Stupid reptiles!" Krang scowled as the brothers were all thrown off and flung across the platform one by one; Leo first, then Raph, then finally Mikey.

All of them groaned as they bounced and rolled before coming to a stop, heads spinning and they had to take a moment to lose the dizziness. Leo had been thrown further than the rest of them and went over the edge.

"Leo, hang on!" Raph called, but their brother grabbed part of the ship and swung himself up again with the momentum.

Once they'd all recovered, the siblings charged at Krang again. "Where's the beacon, Donnie? We're running out of time!" Leo yelled, the four of them ducking and diving all over to avoid Krang's attacks, the ship continuing to build around them.

"You already have," Krang sneered, knocking them away from him. "Prepare to watch your city crumble."

"What's happening, Donnie?" Raph asked as they heard a strange noise, and something told them it was bad.

"I was right. It's a massive weapons system," he told them. "He's bringing it online!"

"I got it!" he exclaimed a moment later. "I found the beacon!"

"It's just... up... there..."

The four of them realised where he was pointing, "Mikey, go!" Leo ordered he held back one of Krang's robotic arms as his brother started running to go get it.

..........................................

Chaos runs towards Emma with her fist balled up arched back, luckily Emma had been training with Splinter to defend herself. She quickly leans back missing the punch to the face but that didn't stop Chaos from quickly roundkicking her in the stomach sending her back groaning in pain.

Emma gets up and slides to the left as Chaos starts to telekinetically throw Shredders knifes at her Emma dodged them except for one that grazes her arm leaving a cut bleeding "Agh!" Emma hisses holding her arm in pain tearing up a bit but shakes her head to focus "No remember what Raph said 'Ninja don't cry they make other people cry!'"

Emma holds out her hands stopping the knifes that were inches away from her face as Chaos uses her powers to try to bring them closer, the girls get into a  telekinetically power struggle of the knifes bleeding quickly at the nose as the knife glow from mint green to red moving back and forth.

Mint green

Red

Mint green

Red

Finally Emma has enough strength to swings her arms upward making them shoot up and stab the ceiling, thankfully it didn't hit anyone up above. Chaos goes to try to summon then back but Emma tackles her as the two girls throw around on the ground punching, scratching, and clawing at each other. 

Chaos lands a clean punch to Emma's eye making her cry out in pain but Emma lands a punch to her nose, Chaos stumbles back holding her now even more bleeding nose she spits out some blood and a loose tooth smirking at Emma evilly "Come on you and I both know you want to do it, like how you wanted annihilate those foot soliders and those stupid cops!! Don't ya wanna be strong!!"

Emma stands up tall clutching her fist with her one good eye glowing bright as she slowly levitates off the ground over Chaos. Pieces of metal start to pull off the ship surrounding her, Chaos jumps trying to levitate but Emma uses her telekinesis to hold her down

"If being strong means hurting innocent people and hurting my family and friends then it's Not WORTH IT!!!"

Chaos looks down for a second before letting out a laugh.

A wicked cold hearted laugh.

"Hahahaha!! You really think everything will just go the way you want it?! You're nothing without me!!"

Emma looks at her squinting her eye raising her hands above her head as the metal part rise "You are nothing but a big bully and jerk!!"

"And I will never be like you."

With that being said Emma let's a final frustrated scream throwing her arms towards her as the metal bolts towards Chaos causing a big hole to burst to the outside.

Finally Chaos was gone.

The giant hole sucked a few scraps of metal out Emma levitates to the hole that she pulled into making her way back up to the surface.

..........................................

"Oh, I'll get that beacon," Mikey grinned, flying past on his rocket-powered skateboard.

"Okay, turtles," Krang growled. "Playtime is over!" There was a blue beam of light and a large cannon suddenly appeared on his chest.

"Whoa!" He barely avoided the shots being fired at him as he made his way towards the beacon . All the while Krang was laughing, but he kept missing Mikey.

He disappeared from sight briefly, but the next time the others saw him Mikey was skating up the side of the Technodrome. "I've vertical!" he laughed as his brothers bolted towards Krang.

Krang saw them coming and chuckled. "Oh, you want some, too?" They were so close to him, but got thrown back as he fired the weapon at their feet and the blast hit the other three turtles hard.

"I got it!"

However, Mikey still had to get to Donnie, so the others continued to distract Krang, which was proving even harder.

"Hey! Heads up, Donnie!"

Mikey skating towards them. He went to pass a metal sphere to Donnie, but he was knocked off course by one of Krang's limbs and hit the platform, dropping it. "The beacon!" he yelled, grabbing it in his hand right as Krang jumped down behind him but luckily Emma pops out of the hole to the side of them, Donnie turns to see her making the others perk up "Emma! You're okay! What happened to your eye?

Before Emma could speak Krang noticed her and gets an evil smirk on his face

"Come here, little girl." He extends his arm towards her, Emma yelped as she turns trying to get away but is pulled back by her wrist. Krang throws her up into the air, Emma yells out in surprise before being put in a bear hug by Krang. "Let me give you a hug. Goodbye." He starts to squeeze making Emma scream out in pain kicking her feet trying to get down as she squirmed "Ahh put me down!! Stop!! Agh you're hurting me!!"

"Raph, Mikey! With me!" Leo called. Not wasting any time, the three of them climbed up the side structures and jumped onboard a piece of the ship as it went past.

"Ahhh guys help me!!" Emma cries out

"Hang on, baby sis!" Leo replied. He steered their ride so it was heading for Krang and Emma, and then they jumped.

"LET HER GO!" Mikey shouted, bringing his weapons down on the alien the same time as Raph and Leo. The three of them stabbed their blades into the armoured suit, and hung on even as Krang thrashed around, trying to dislodge them.

Raph growled, "Nobody messes..." Before he finished, they all jumped away, Raph ripping off the robotic head as he did, and that left the path clear for Donnie, who had the taser on the end of his bō staff raised and ready as he leapt at Krang.

"With Emma!" he finished, stabbing it down and electrocuting Krang, also short-circuiting the suit and forcing him to release Emma.

Leo quickly catches her before she hits the floor he looks at her with wide eyed going into full big brother mode "Emma look at me, look at me baby are you hurt?"

"I-I'm okay m-my back just hurts a little." Emma groans rubbing her back that is for sure starting to develop bruises.

As the robot suit spasmed and convulsed, it wasn't long before it collapsed to the ground at their feet. "Guys, Krang is down," Leo stated, "but his ship's still building."

Mikey was pleased to see he still had the beacon in hand. "Donnie!"

"Drone activated."

As Mikey threw the beacon up into the air, the attachment on the bottom of the drone caught it and Donnie began steering it away from them, heading for the last remaining gap in the ship.

All of them watched anxiously, for they could see the final remaining piece about to fit into place.

Donnie gritted his teeth. "It's gonna be close." The five of them moved to the very edge, and as they watched Donnie contacted April and the others at Pier 90. "Guys, now! Close the portal now!" he ordered frantically.

The drone made it through the gap with centimetres to spare... and as it flew away the pieces of the Technodrome then started to fall apart, following after the beacon towards the still-open portal in the sky.

"YES!" Donnie cheered and the others followed suit, jumping up and down, high-fiving and fist-bumping with pure happiness that the plan had worked.

They were still laughing and cheering even as they hitched a ride on one of the ship's pieces, planning to get off at the nearest building.

"Okay, this is our stop," Leo said, pointing at a building rooftop, Emma holds on tight to him with her arms wrapped around his neck as he held her close.

With a grunt, all of them jumped, the four brothers landing on the roof and rolling to absorb the impact,

None of them were expecting to then be thrown back several metres by a resounding shockwave as an effect of the portal closing, knocking them off their feet and halting their cheering briefly

"It's cool. It's cool," Mikey panted.

"Yeah, I knew that would work," Leo said smugly.

Mikey stared at him. "Wait, so you seriously thought us four teenagers and a seven year old could save the whole world?" he asked.

"Sure," Leo smiled. "Guys, we got something no one else has."

Emma and her brothers chuckled knowingly, bringing their hands in a pile for a cheer. It was then two different shouts - one from Raph and the other from Emma, Leo, Donnie and Mikey

They all looked at Raph. "Garbage truck?" Leo repeated.

Raph paused. "I..."

"Well, we do have one," Mikey agreed.

"The other one."

"Oh, the other one. Alright."

Emma giggles hysterically as they put their hands in a pile, going for another cheer as they shouted, "TURTLE POWER!" and threw their hands in the air.

..........................................

Later that night, Emma, her brothers and Splinter joined April, Casey, Vern and a handful of the New York Police Department on Liberty Island, where a small ceremony was being held at the foot of the Statue of Liberty.

"For your incredible valour within this community, and for your uncompromising cooperation with this agency," Vincent said to the five siblings, "I present to you the keys to the city, a symbol of our appreciation, respect, and for our continued partnership."

"To you brothers," Vincent continued, "Leonardo, Raphael, Donatello, Michelangelo" As she said each of their names, they all beamed at the audience "Uh... Last name?" she whispered.

The siblings glanced at each other. "Uh... Not so much," Donnie replied softly.

"I never thought of that. That's no fair," Mikey added, and the others threw him a look.

"How about Emma picks on." Leo looks over at the youngest sibling who puts a finger to her chin looking up at the sky thinking as everyone looked at her.

"How about... Hamato!"

"Hamato?"

"It's a Japanese name Daddy showed a book full of them one time."

Vincent thought for a minute and smiles at her "Then Hamato it is." Vincent nodded "Congratulations," she said, starting to applaud, and everyone followed suit - April, Casey and Vern probably being three of the most enthusiastic while Splinter looked on proudly.

"Wait," Raph said suddenly. "This doesn't feel right."

Leo nodded. "We didn't do this alone. It was never just the four of us."

"Mm-hmm." Mikey picked Emma up holding her in his arms with a big proud smile. "Our little sister Emma helped too!

"Without her help a lot of our accomplishments wouldn't have been possible," Donnie agreed

"She is just as much of a hero as we are," Raph finished ruffing her hair a bit, Emma smiles turning  bright red holding up her hands to cover up her face hiding in Mikey's shoulder causing everyone to awe.

"She does that when she's embarrassed." Leo smirks whispering to the people making them chuckle.

"Then it's a good thing we have another key."

Vincent held up another key to the city. Emma perks up in surprise before she lowered her head slightly as she slipped it around her neck, Emma beams with pride as Vincent smiled at her.

"Congratulations and also one more thing for you."

Vincent turns gesturing someone to come forward, Dr Higgston walks up smiling at Emma "You touch all of our hearts Emma and we've decided that if you'd like you want to you can talk and see Dr Higgston anytime." She gestured to the doctor she turns to the turtles and splinter knowing they were gonna say something "And don't worry it's free of charge."

Vincent grabs a paper from a cop handing it to her reading it "And on behalf of the NYPD we will also be offer Emma a free scholarship to any school she choose to go to from now until the end of her graduating year of high school and also college.. if she chooses too."

"Oh she's going college." Donnie crosses his arms nodding his head as the other brothers playfully roll their at him.

The applause started up again, and the applause was more enthusiastic. Emma couldn't stop smiling and neither could her brothers.

As the applause faded and the party split up slightly, Emma and her brothers all crowded in to look at their keys to the city, still a bit in awe and shock about this.

"My key's totally bigger," Mikey was saying, admiring his along with Donnie. "It's bigger than your key, man," he told Donnie. "I got the big key."

Their laughter died down as Vincent came over to them. "I think you should give people more credit," she said quietly. "They'll accept you now."

The siblings all shared a look, thinking the same thing. "You're probably right," Raph agreed. "But, uh... I think we'll stick with the arrangement we've had."

"If you ever need us," Leo told her with a smile, "April knows where to find us."

Vincent looked genuinely surprised at their response. "Really?" she said, looking at each of them with a kind smile. "You could live a normal life, like the rest of us."

"Normal?" Raph repeated, smirking as his eyes flicked to each of his siblings. "What fun is that?"

Emma looks at her big brother with a smile before turning to look at the Statue of Liberty

She had just saved New York City

And the best part

She did it along side her family

Maybe having superpowers isn't that bad after all.
