DISCLAIMER- I do not own Wild Kratts.

I hope you enjoy this story! Almost all the WK fanfics I write will all be in a "series" together, so to understand them, you'll need to read them in order. This is episode 1- Werewolf. (Okay, yes, there is blood, but c'mon! I can't write a story without blood!). This is a Caviva story, btw, so if you're a Caviva fan, enjoy! If you aren't a Caviva fan, enjoy!

Wild Kratts- Werewolf (episode 1)

Chapter 1

Chris and Martin were running through the North American forest in wolf power, off to save a wolf and her pups from Zach Varmitech. When they reached the danger, they found that he had a scared mother wolf with six pups, only weeks old, cornered up against a rock and trees.

"Zach. Leave the wolves alone." Chris declared as he stood up. Martin was right behind him.

"Ah, Wild Rats." Zach smirked. "I've been expecting you."

"You have?" Martin asked.

"Why yes. I was hoping you'd come to test out my new invention." He started to pull something out from behind his back.

"What ever it is, we don't care." Chris said, taking a step forwards.

"You don't have to care. Only stand still." Zach said as he ran up to them and locked two metal collars around each of their necks. He then pulled out a remote, though Chris and Martin didn't realize he did for they were struggling to get the collars off. "Now sit!" Zach pressed a button on the remote and the Kratt brothers instantly sat in a dog position. "You see, I've designed these collars to let me control who ever is wearing them. And that would be you two. Oh and I almost forgot. For you're first test, you will have to clean my jet. And don't worry, there will be other tests!" Zack laughed. He controlled Chris and Martin to walk onto his ship.

They looked around the sparkling place, not seeing anything in need of cleaning. The only thing out of place was a chair pulled away from a table. Martin just went over and pushed it back in.

Zach just stared for a moment then said "Good. Now for your next test. You are each to bring me back a small rodent you catch. I must make sure you are willing to catch an animal. Now GO!" He pressed another button and the brothers ran off the ship.

Chris stalked through the forest, hardly noticing that he did not have a more strong human mindset. Being part wolf, being in the creature power suit, for it to work, it alters the wearer's DNA. Thus also changing part of the wearer's mindset. The collar around Chris's neck made it so that his mindset was not more human, as it usually is, but more wolf, bringing out his more animal side.

There. He saw a rat sitting peacefully on a tree root, nibbling away at a piece of grass seed. Chris crouched down and slowly crept forwards. Now he was just a few feet away from the rodent. With a leap, he pounced on the creature, gently grabbing it's scruff with his teeth. Usually he would never do this, but with the collar amplifying his wolf mindset, he did it anyways. But he was careful with the rat, he still did have a human mindset, it just wasn't as influential as it should be.

He padded through the woods until he got back to the jet. Martin was already here and sitting. Chris handed Zach the squirming rat.

"AH!" Zach screamed. Chris dropped the rat in sudden shock and thankfully watched it scurry away, unharmed.

"Ugh." Zach muttered as he brushed of his shirt. "Okay. For your third and final test, I want you to... attack the Wild Kratts crew." An evil grin lit up his face.

Chris felt uneasy and like he wanted to run away from himself as he and Martin were forced to walk in the direction that the Tortuga was parked in. Chris could see that Martin felt the same way.

Despite the way Chris felt, his appearance was entirely different. He looked almost as joyful as an actual wolf as it crept up on an injured lamb. He knew how he looked right then. It made him feel sick. His crew would at first see a kind and friendly crew member back from a mission, but then go crazy, trying to inflict harm on them.

He felt like dying as the Tortuga came into view. He struggled to stop walking, but that did nothing.

He and his brother got into a standing position and walked in as if nothing was wrong.

"Hi guys." Aviva roller-skated up to them, a smile on her face. "How was the mission?" She asked as she turned towards the table and took a metal L pipe out of a box.

Instead of an answer, the brothers got down on all fours and snarled fiercely.

"Guys...?" Aviva turned around, only to have Chris jump at her. He could see the confused and shocked fear in her eyes. That made him feel like dying. But then he did worse. As he watched Martin charge at Koki and Jimmy, Chris sunk his teeth into the flesh of Aviva's arm. He felt nauseating as the blood dripped down his tongue and the awful taste of iron took over his mouth. His heart broke as he heard Aviva's scream of pain and horror. She did the first thing she could think of; Whack him in the head with the L pipe.

He fell to the ground, anger on his face, but horror and fear in his heart. He wished the L pipe had knocked him out, but it didn't. Instead he ran at Aviva and sunk his teeth into her ankle. He shook his head viciously as if trying to tear off a piece of tough meat from a fresh kill.

Aviva kicked her leg desperate to get loose from Chris's strong grip on her. Finally, she got loose. She hooked his back leg with her foot and yanked it underneath him, flipping him over so he was lying on his back. Aviva instantly pinned Chris down to the floor. To make sure he didn't get up, she had her hand digging into his neck, slightly choking him, and her knee pushing into his gut. "Why are you-" She stopped mid sentence as she noticed the collar he had on. She instantly knew it was Zach's collar because of the signature red 'V' marking the dark gray metal.

"Oh- oh, I knew you'd never hurt us." She said, still pinning him down. "I'll get you out of this, I promise." Aviva lifted off of him a little as she reached for something on the desk. Chris tried desperately to fight the urge to jump up and sink his teeth into Aviva's neck. "Pin Martin!" she shouted to Koki and Jimmy Z. Aviva leaned back down, her knee digging back into his gut. Chris could see what she had in her hand. It looked like a pen, but he knew it wasn't, for that would be nearly ineffective against a wolf. Aviva pushed down a button on the side of the object and a warm, red beam of light came shooting from the tip. It was a laser cutter! She was careful as she used the burning weapon to cut loose the collar. As soon as she had done so, she grabbed the collar, bent it a little (with a lot of effort), and tore it off Chris, then pressed his deactivation button. Finally, he had full control again.

He lay there for a few seconds, then as Aviva slowly moved off of him, he immediately jumped up and wrapped his arms around Aviva. "I'm sorry... I'm so sorry I ever hurt you."

Aviva was stunned for a second on how Chris had reacted. He usually wasn't like this. Aviva hesitated for a second, shaking off her question, and hugged Chris back. "It's alright. I'm fine." Aviva assured him. She then let go and pulled away to help a struggling Martin.

Chris watched as she did the same to his brother. But instead of Martin reacting the same Chris had, he sat there, tears forming in his eyes as he apologized over and over again. Chris could already feel tears running down his cheeks, mixing with the dirt and blood. Chris could feel his anger, regret, and sorrow rising inside him. Zach would pay.

Thanks, for reading my story, I really hoped you enjoyed it! I already have the rest written out (that's all I do at school), but I still need to type it. I also have a tendency to prograstinate, so next chapter might not be up right away. Depends on how late I stay up :P.

Well anyways, this is the most blood in the story. So don't worry, those of you who don't like blood. :3

Next chapter will be up soon!
