Author's Note: So few things to help you understand the story. First of all, Della isn't related to the other lab rats. Second, she's the same age as Chase which is 15. Third, she's only been up stairs 5 times in her life and she spends the rest in the lab. And last this is kind of an' Adam/OC/Chase story so if you want you can give me requests on a pairing, also the link to what Della look's like is on my profile. Anyway that's about it and I hope you enjoy the story, and please review if you can it would mean a lot.

Leo cautiously walked out of the elevator and stared at the table full of gadgets in awe "Wow, my new dad is batman!" He exclaimed excitedly, the double doors opposite the elevator suddenly slid open and he hid behind the stack of yellow gas tanks. He peeked through the gaps between the tanks to see a young male teen with dark brown gelled hair run through frantically and re-close the double doors.

"Good luck getting in! That steel door's thicker than' your head" he exclaimed taking a few steps back. Leo's eyes widened as a guy much bigger than' the previous teen punched his way through the doors "Well there's another way to get in" The younger guy said nervously. The larger teen stormed towards him and lifted him high in the air without any struggle.

"Give me back my E-pod" he demanded.

"I don't have it" The younger boy replied struggling to get down. Leo's eyes once again widened and he suddenly felt the familiar nervous tingle in his stomach. He tore his eyes away from the fighting boys to see a thin teenage girl with brown hair walk towards them holding what looked like an' I-pod.

"You took my E-pod" The large boy gasped pointing to her and dropping the younger male to the floor,

"Taylor Swift mega-mix. Really?" she asked taking the headphones out of her ears.

"I find her soothing" The taller boy replied. She nodded in disbelief and turned to walk away. Leo flinched and held back a scream as two red beams shot out of the taller male's eyes and flew straight passed the girls head, she turned around slowly with a glare.

"Oh I know you didn't shoot that lazer at me" she said her tone slightly threatening.

"Oh sorry it was a terrible mistake, just like your face" The guy said smugly. In two short seconds the girl had ran towards him and shoved him into the gas tanks causing them to fall down. Leo froze knowing he'd been spotted and the three un-named teens screamed, as soon as they stopped Leo released his own loud scream.

They all paused before screaming at the same time and suddenly stopping a few seconds later, Leo let out a scared squeal and ran into the next room only to crash into a soft surface "Oh my god!" A young female voice shouted, Leo slowly looked up to see another female teen with the same clothes and hairstyle as the other girl. He once again screamed and ran around her before walking backwards until he hit a hard surface, he soon found himself cornered and the four teenagers stared at him suspiciously.

"Okay I don't play this card too often but...Mom!" Leo screamed as loud as he could and soon his mental prayers were answered when his mother and step-father walked into the room.

"Leo there you are" His mother said lightly hugging her son as he clung to her in fear "Wow what is this place? Who are they?" she asked pointing to the four teenagers stood in a straight line.

"They are...uh...a boy band I've been working with and the twist is. Two of them are girl's" Donald Davenport replied nervously. The two girls smiled innocently and one wiggled her fingers in a greeting manner.

"Okay they're part of a secret project I've been developing. Genetically engineered superhuman siblings" Donald admitted the excitement clear in his voice, he sighed at the confused look's his new family were giving him and decided to introduce the bionics "Tasha, Leo. Meet Adam, Bree, Chase and Della. The greatest combination of biology and technology ever developed, I don't wanna brag but I am incredibly smart" he exclaimed proudly. Tasha turned to her son with a questioning expression and he shrugged in response.

"Don't look at me, I told you to stay away from internet dating" he replied. She nodded and turned back to the group.

"So they're robots?" she asked hesitatingly. The teen's gasped loudly and Tasha's eyes widened slightly.

"What?"

"Hey!"

"Oh no she didn't!"

They exclaimed one after the other, the youngest looking teen stayed quiet but appeared to be just as insulted as the other three.

"No Tasha they're human, I've just given them each a set of bionic ability's controlled by a micro-chip implant in their necks. It sounds a lot more complicated than' it is" Donald explained shrugging. Tasha and Leo slowly nodded trying to process their new information.

"See Adam is all brute strength, Bree has speed and agility, Chase has super senses and a superior intelligence. And Della has Cryokinesis" Donald exclaimed. Both Tasha and Leo gave him very confused looks at the last word "It means she can manipulate ice. But she hasn't quite learned how to create it yet" he explained, they nodded and Tasha chuckled nervously while walking forward.

"Donald, there are children living in our basement!" she shouted as she reached him. He winced and shrugged apologetically "And you told me you didn't have any kids" she added crossing her arms angrily.

"Well technically they're not my kids. My old partner made me their godfather so when he and his wife were killed during one of their experiments I took them in. But Della actually is my daughter" he admitted. The teens looked down sadly so he changed to the topic of conversation a little "This is a scientific habitat! I mean look at it it's got a game room and a rock wall anything a kid could ask for. I've created this place so that they could train in the utmost of comfort and technology" he exclaimed leaning against the counter.

"It's true! The toilet's have seat warmers that talk" Adam exclaimed.

"What do they say?" Leo asked slightly curious.

"Well various depending on..." he paused as Leo held up a hand to stop him continuing the disturbing explanation.

"Donald I don't know what to make of this, some new wives get surprised with a honeymoon in Hawaii or a cruise. Bionic teenagers were not on our wedding registry" Tasha said shaking her head.

"They have to stay down here for their own safety, this is all very top secret but as soon as their training is complete they'll be able to handle any crisis or problem that the world throw's at them" Donald replied shrugging.

"I wanna go to Alaska" Della admitted smiling and revealing the dimples in her cheeks.

"I wanna go to the pyramids" Chase said raising his hand.

"I wanna go to Paris" Bree added.

"I wanna go upstairs" Adam said boredly.

"Hey what are those? Time machines?" Leo asked hopefully. He stared at the four large, circled and glass chambers near the back wall.

"No they're not time machines, time machines are actually in the shop. These are my biologically regulated atmospheric chambers where my bionic creations live and sleep and eat" he explained once again becoming excited from talking about his inventions "Which reminds me it's dinner time" he added walking towards one of the computer counters. The bionic teens ran towards the chambers excitedly and closed the glass doors.

Adam had the chamber on the far left while Bree occupied the chamber on the far right, Chase had the one on Bree's right between the girls while Della was on Adam's left inbetween the two boys. Donald lightly touched the computer screen as the bionics put on their eye-protection goggles.

"Ready?!" he asked, they all nodded and he once again pressed the screen allowing the small food pellets to fall down into the chambers "These are my protein pellets" Donald explained as he, Leo and Tasha watched the bionics eat the small pieces of food "Whatever they don't catch is tomorrow's breakfast" he shrugged, Leo nodded at him with a slightly disturbed look before turning back to watch the teens.
