The city of New York was wild. Emphases on the was. It had been over a decade since the krang had disappeared, the foot had been dismantled, and earth had made peace with the majority of species they had contact with. The disappearance of the pink brain-like aliens obviously meant no more mutagen as well and all mutants had settled into hiding. Now-a-days, things were incredibly boring… or that's what the 4 green teens that lived below it all believed.

The sound of battle echoed throughout the sewers. A loud slam was heard as a certain yellow eyed mutant was thrown on to his shell. He grunted through bared teeth before grabbing his attackers legs with his tail causing the now unbalanced, mint skinned, boy to fall backward onto his yellow hair. The first mutant flipped onto his feet, placing one of them on the others orange shirt to keep him down. His new found victory was short lived when another boy with a black haired buzz cut was thrown into him. The boy with blond hair whooped as he jumped up and flipped away.

"Eat it George!" He shouted through a smile before running off to get a piece of the fight going on between a red headed turtle mutant and a girl in a pony tail who was swinging a baseball bat a her.

George pointed a death glare at the boy who had not managed to get off of him yet. He let out a frightened 'eep' before scampering off of him and pointing a thin arm at a navy green mutant wearing a red jumpsuit.

"Rhonda-threw-me." He sputtered at lightning speed.

George shifted his yellow gaze to meet Rhonda's salamander-like emerald eyes.

"Oops." She said threw crossed arms and a sly grin.

"Hey! Stop ganging up on me! DAN!" The girl in the ponytail whined.

Dan got up from his spot next to George and edged around Rhonda as he ran to help his sister. Much to the black haired boy's dismay, the redhead mutant turned to meet him. He started to sweet as he lowered himself into a fighting stance. The mutant threw threw her staff out of her three fingered hand and assumed a pose similar to his own. Dan mustered up all the courage he had and threw a punch at her. She dodged and blocked but she didn't fight back. Dan tried again but was once again foiled. Dan threw strike after strike at her but to no avail.

"Quit going easy on him Bree!" His sister shouted as she blocked one of the blond haired boy's attacks.

"KATIE!" Dan yelled in distress, there was no way he would win against the red head if she went all out.

Bree turned around and stuck her tongue out at her best friend who smirked in response. Dan took this as an opportunity and tried to kick Bree in the back. She flipped over him, backward, grabbing the collar of his black ninja suit and forcing over his head. She landed behind him and swept him off of his feet. Once his is on cleared, Dan was met with the sight of Bree's caring brown eyes looking down at him. No doubt he was embarrassed but her smile made it a little better. She offered him her hand which he graciously took.

"That's enough training for today." She announced.

"Oh come on!" Katie whined again, "I was just about to kick Cody's butt!"

"Nuh-uh!" The blond boy insisted.

"Yuh-huh."

"If you two continue this I will kill you both." George cut them off.

He and Rhonda trudged over to them after their sparring session, that Rhonda had inevitably won.

"Fine. See you guys later." Katie said, grabbing Dan and dragging him behind her.

"Can't you stay for a few hours?" Rhonda asked, giving them her best puppy dog eyes.

Cody did the same and Bree bit her lip in anticipation. None of them, with the exception of George, wanted the twins to go so soon.

"Sorry guys." Dan responded "I have to watch Amber."

"And I've got a date with Ryder." Katie added.

"Again?" Bree asked through a giggle.

No doubt she was happy for her best friend but they just went out yesterday. Now it was Katie's turn to stick her tongue out.

"I'll try to bring Amber here if Mom and Dad let me." Dan told his hybrid friends.

They all smiled, including George. He didn't like the twins so much but he had a soft spot for their 10 year old sister.

The two humans grabbed their things and walked down a sewer pipe, waving as they went.

"Successful training period?" Leo's voice came.

The 4 teens turned to see their parents. Of course they had been watching. Bree didn't know if it was successful. It wasn't bad but there weren't any breakthroughs either. She just nodded in confirmation which caused her parents to smile. There was no doubt in Bree's mind that Donnie and April were proud of her; she just didn't know if she deserved that pride. She hadn't really done anything to earn being the leader. Even so, she was in charge now, she had a responsibility and wouldn't let them down. But a responsibility to what exactly? Like what was said before, there hasn't been a threat in years.
