AN: Hello peeps, Asori here. This is my first post in a long time, my first post ever for Lab Rats. I am excited to share this with you all, and I hope you enjoy this story.

Some things you may want to note: this is slightly AU and takes place during the second season, there are definitely more characters than listed, and while it does have action scenes (and resulting injuries) as well as some mature self-discovery themes, it is guaranteed clean and the rating is no higher than K+. Oh, and I've made a point of adding plenty of comic relief in the style of the TV show, so feel free to laugh. If there is anything else you may wish to know, check out my (chaotic) profile, and hopefully your questions will be answered. If not, send me a PM. I like making friends.

I will try to update this pretty regularly (every-few-days-ish), I promise that there won't be many ANs, and so that the story is cohesive and is at its full potential, it is pre-written (and fairly good, if I do say so myself). Please feel free to rate and review; like many of you, I to am an aspiring author.

Disclaimer: I do not own Lab Rats or any of the characters, just the plot.

Anywho, enjoy!

"Alright guys, today we are going to try something different," Mr. Davenport began, commanding the attention of his adopted children(/science projects, if he must be honest). The three who were participating in the daily training (the bionics), Adam, Bree, and Chase, looked to their father figure with an equal measure of curiosity and boredom; clearly they did not expect much. Leo, their step-brother and Mr. Davenport's step-son, didn't even look up from the gadget he was fiddling with.

"You all know about Chase's commando app, Spike," Mr. Davenport started to say, but Leo interrupted, saying "Yeah, nobody likes that guy."

"You hear that, Chase? Nobody likes you!" Adam pitched in with a laugh.

"Adam! He was talking about Spike!" Chase barked, scowling.

"Well nobody likes you either," Adam muttered to himself, but it was still loud enough for everyone else to hear, especially Chase.

Mr. Davenport cleared his throat before Chase could retort, and with that the bickering siblings fell silent and turned back to him. He sighed, asking "Will you let me speak now?" When everyone nodded in consent, he continued. "I've told you what Spike is and that he is meant to protect Chase, when for Adam and Bree, their strength and speed would protect them. Today's training is going to help the three of you work together when Spike is in the picture, but also so that you, Adam and Bree, can learn to fight without your bionics better by being pitted against Spike," Mr. Davenport explained.

There was a stunned silence before Bree broke it, asking in shock "Are you crazy? Are you trying to kill us?"

"Mr. Davenport, you've got to be joking," Chase scoffed.

"No Chase, I'm not," Mr. Davenport deadpanned, looking at each of them in turn. "It only makes sense; if something was to happen during one of your missions and you turned into Spike," Mr. Davenport said, turning to Chase at this point, "your siblings would need to know how to work with him to complete it. And if Spike were to get out of hand, they would need to know how to subdue him."

"I don't like it, not one bit," Bree said, frowning in concern.

"It's necessary," Mr. Davenport replied.

"I don't want to be Spike!" Chase burst out. "Don't you get it? I really don't like being Spike. What if I severely injured any of you? How could I live with myself?"

"And that is why we are training this way today," Mr. Davenport said, pronouncing every syllable clearly, as if talking to a young child.

"I'm talking about the possibility that I would hurt you today," Chase said, his turn to speak slowly and clearly. "According to my calculations, there is an eighty-six percent chance of any of you at least sustaining an injury. If I hurt Adam or Bree today, there won't be any future missions."

"And that's why I will make sure we take the right precautions," Mr. Davenport said in order to calm them down. "I will keep control of Spike with this remote (that I invented)," he said cockily, holding up a small tablet, "and the three of you will be in the simulator (that I invented)." Mr. Davenport glanced at the bionics, making sure that they understood.

Bree, Chase, and Leo looked at each other worriedly, but Adam frowned in confusion (which was pretty normal for him), saying "I don't get what the big deal is. Spike is only in Chase's weak little body, so it won't be that bad, right?"

Chase threw Adam a glare, a wide-eyed Leo saying "Oh, trust me; you should be very worried about Spike. I would know!"

"Okay, enough talk," Mr. Davenport cut in. "Adam, Bree, and Chase, go put on your simulator goggles and get on the platform so that we can do this."

Grudgingly they consented, Chase looking a little pale. As the lab around them faded and the scene of an all but empty city street came into existence around them, Chase suddenly began exclaiming "I didn't –" when he cut himself off. He froze, scowling. He looked at everything around him, but when his gaze fell on his siblings, he froze yet again, meeting their stares coldly.

"What are you meatheads staring at?" he growled, his voice low and menacing, especially compared to his normally high-pitched pubescent voice.

"Hey Spike! How's it going?" Bree said as sweetly as she could, trying to hide her nervousness.

Spike raised an eyebrow in confusion, but didn't bother to answer her conversational question. The 'bad guys' (henchmen working for the leader of an illegal drug empire) chose that moment to attack, coming from behind Spike.

"Watch out!" Bree shouted, but the man had already grabbed Spike around the throat. Spike pulled his head forward before whipping it back, smashing the man's nose. The man cried out in pain, but he didn't lessen his deadly grip, only holding Spike out further so he couldn't pull that stunt again. Spike tried using his elbows and fists to hit his way free, but the man seemed impervious to his efforts. Spike's face was quickly turning purple, but he didn't give up his struggle; if anything, he thrashed about even more fervently.

Meanwhile Adam and Bree were engaged with their own opponents, Bree using her speed to create a cyclone around several men while Adam worked to catch his swift foe who kept dancing just out of his reach. Once Adam eventually caught him, he threw the man into the wall of a nearby building, effectively knocking him out. Turning to find his next victim, Adam saw that Spike still was not free, but was in fact about to fall unconscious due to being unable to breathe.

Without further contemplation, Adam shot his heat-vision at Spike's captor, nearly hitting Spike as he did. As soon as he was free, Spike bent over, coughing and gasping for air. Adam moved on to confront two more men who were going to work together to take down the bionic strongman, and he quickly forgot the app that was controlling his little brother.

As this took place, Bree had subdued the three men she had trapped in her cyclone, smiling to herself at how easy it had been. She scanned the situation around her and her brothers, seeing to her dismay that they were still far outnumbered, almost three to one, from what she could tell. Bree saw that Adam was being goaded by three different men all around him, and she thought that she might help him (though he probably didn't need it). But then she saw the whirlwind of terror that was Chase – no, not Chase, Spike – in the midst of five men, but even as she watched, their advantage dwindled to four, then three….

Wow, Spike really is a machine! Bree thought to herself, speeding over to try to help him. There was literally a pile of conquered opponents on the ground around him, which made it difficult for anyone to approach him.

She caught a man unaware and made quick work of him, even as Spike simultaneously took down the last two. Bree was about to commend him when she felt pain explode in her abdomen and she found herself on the ground. She incredulously looked up at Spike, who was standing over her triumphantly.

"You idiot, I'm not your enemy!" she cried as she rolled out of his reach before he could do anymore damage. She scrambled to her feet, standing in a defensive position in case he would attack her again.

"Enemies, friends, what's the difference?" he replied with a sneer.

"We're family!" Bree exclaimed.

"So? What's the difference?" he asked again, closing the distance between them. He lunged forward to strike her, but she merely avoided him by using her super-speed. He continued to press a flurry of dizzying attacks, but her speed gave her the edge. Spike never so much as touched her.

"Why don't you fight me?" he yelled, obviously frustrated.

"You're my brother!" Bree replied.

"Weakness! You're a lily-livered coward!" Spike growled, dealing what would have been a mortal blow had he hit his mark; but instead his hand just passed through the empty air where she had been, causing him to momentarily lose his balance.

"I simply refuse to fight you," she said haughtily, dodging Spike yet again and again.

"Hey, leaving me out of the fun again?" Adam whined, walking up to them from behind Spike, who, without warning, turned on him suddenly and began pounding him with hit after hit. "Whoa bro!" Adam exclaimed in surprise at first, but it quickly turned into amusement. "Little Chasey is so weak that Spikey can't even hurt me!" Adam laughed.

Spike roared in fury, redoubling his efforts, but still he didn't seem to have much effect on the older and larger boy, who didn't try very hard to defend himself, further infuriating the app.

"This is so –" Adam began to say, but he was unable to finish as he yelped in pain, falling to the ground as Spike finally scored a crippling strike.

"That's for nearly blasting me with your lasers," Spike snarled before kicking him, "and that's for taunting me!"

"Hey, you leave him alone!" Bree shouted, speeding over before he could do anything more to a moaning Adam, who was unable to get back up. She stood between Spike and Adam, lifting her chin defiantly.

Quick enough to rival super-speed, Spike grabbed Bree's neck, pulling her face close to his. "Caught you!" he gloated victoriously before quickly turning vehement again. "Give me one good reason why I shouldn't rip your head off and use it as a bowling ball," he spat.

Terrified, Bree couldn't find the words to convince him to spare her. Even if she would have been able to, his fingers were digging into her neck with such force that she was unable to muster enough breath to cry out in pain, much less for help. She could only hopelessly look into Spike's chilling eyes, wondering how he could be so coldhearted.

But even as she watched, she saw those hard eyes melt into confusion, followed closely by horror. His eyes widening and his mouth forming an O, he quickly let go of her and backed away, looking just as frightened as everyone else was. Chase was back.

As soon as Chase had let go, Bree sucked in air furiously, her tunnel vision subsiding as she did so. Feeling recovered enough, she looked around to see that they were back in the lab. Mr. Davenport and Leo had rushed to Adam's side, but seeing that he was okay, the billionaire decided to leave Leo to watch him and leapt up to check on Bree.

"Are you okay?" he asked her, his concern evident.

"Yes," she croaked before falling prey to a coughing fit.

He examined her neck, saying reluctantly "You will probably have some bruising, but you will live." As she nodded, he moved on to check in with the youngest of his bionic children, who had his back turned to the others.

"Hey Chase, buddy," Mr. Davenport greeted him gently. Chase didn't respond, remaining motionless. "Chase," Mr. Davenport tried again.

Chase ripped off his goggles and threw them to the ground as he swiftly turned to face his father-figure, shouting "What?!" Everyone froze, turning to look at him. Chase was clenching his teeth, but it wasn't hard to see that his lower jaw was trembling with emotion, his eyes rimmed with red. After a moment of icy silence, Chase turned away, muttering hoarsely "Leave me alone," before stalking out of the lab.
