A/N: SHE LIVES! Sorry I haven't written anything in so long, school is kicking my butt! My other laptop decided to stop working so I had to go out and buy a new one, which caused me to lose my Fast & Furious sequel. I did manage to save my TMNT story, which I will try to start working on very soon for those who are waiting for that one. I've been on an Avengers-kick recently so here is a story about my Avengers character! Please let me know what you guys think and if I should continue it! Please review, follow, and fav! Thanks!

Disclaimer: I don't own anything but Katherine!

Katherine Howlett turned her gaze from the fire when her little brother, James Howlett, coughed. He was always getting sick, though, she didn't know why. She or their older half-brother, Victor Creed, were never sick. Victor sat off to the side, filing his nails into claws, a habit she'd seen him develop over time.

"You're always sick." Victor said the very thought that'd just run through Katherine's head. James coughed again.

"You were sick when you were my age." He said back. Victor watched him for a moment before looking back down at his nails (claws). The door opened a moment later, causing Victor and Katherine to stand quickly. Victor hid the file and his clawed hands behind his back and the fire behind Katherine flickered in an odd manner. A few years ago, she'd learned that she could control the elements, weather, and things of nature such as trees. James' and Katherine's father walked in.

"Evening sir." Victor said politely.

"Evening Victor." Her father said back. "I didn't realize you were still here."

"I was just keeping James and Katherine company, sir, if that's all right." Victor answered the man, watching him as he sat down on James' bedside. Her father had his back to her and Victor so she couldn't see his facial expression. The man had never been fond of the boy, considering Katherine was around his age. He deemed her impressionable and that Victor would only corrupt her in some way.

"Very kind of you." He said to Victor before turning back to James. "Any better, son?" He laid a hand on James' forehead.

"Still cold, father." James answered.

"Just a mild fever. You'll be all right in the morning." Their father said.

"You always say that." James said with a smile. Their father laid his hand over James', chuckling softly.

"And you always pull through, don't you?" He asked. Katherine and Victor watched the scene silently. James had always been a favorite compared to Katherine, at least to their father.

"Yeah."

"Now, you taking your medicine?" Their father asked before there was a pounding at the door.

"Elizabeth! Elizabeth!" Thomas Logan shouted, the four of them could hear him from the second story.

"Your father's drunk again." The man said drawing Victor's attention to him. Katherine moved a little closer to her older brother. It had taken her a while to come to terms with the fact that the man sitting on the bed wasn't their biological father but their step-father. Thomas Logan, the man beating on the door downstairs, was their father. "You should help him home, Victor." John Howlett, their "father", said over his shoulder.

"It's not my name he's calling, sir." Victor said, gently holding Katherine's hand as she placed it in his. John got up quickly, moving to the door.

"Father!" James called after him.

"Stay where you are James, Katherine." Then he was gone. They could hear their mother yelling downstairs.

"Father!" James called again. Victor released Katherine's hand, walking to the door; he looked back at his younger siblings before closing the door behind him. They listened to the arguing for a moment before there was a gunshot, causing both Howlett children to jump. James suddenly jumped out of bed, running to the door.

"James! No!" Katherine called after him before running after the boy. They came to the edge of the balcony and looked over. John was lying dead and Thomas was holding their mother, Elizabeth, back from getting to him. James ran down the stairs and Katherine followed, trying to stop the boy. He ran to their downed father, kneeling next to him. John said something to the boy before he stilled, dead.

"James? Katherine?" Thomas asked carefully. "There are things you don't understand."

"Don't." Elizabeth said, trying to get away from him.

"I need them to know."

"Please don't."

"No more lies."

"James…" Katherine glanced at her younger brother, her eyes widened when she saw three pieces of bone extended through the skin from between the areas of his knuckles. He was terrified. Victor, Katherine, Elizabeth, and Thomas watched on in shocked silence. James screamed before standing up and running towards Thomas, impaling him through the stomach with all six claws. Thomas said something to James, causing him to look at their mother before he ran out the open door. It didn't take long for Victor and Katherine to catch up with him. Victor tackled him to the ground, both stood up and James turned to face them, hands positioned to fight them if he needed to.

"I didn't mean it! I didn't mean it!" James said to them in a frantic voice.

"Yes, you did!" Victor said in a firm voice. "He deserved it and you gave it to him. We're family, Jimmy. You realize that? You, me, and Katherine. And family protects each other. You have to be hard now, hard so nothing can ever touch us." Victor said as he laid his hands on Jams' shoulders. Katherine stepped up so she was standing at their side.

"I want to go home." James said in a small voice.

"We can't." Katherine said, drawing their younger brother's attention to her. "We have to stick together, no matter what."

"And take care of anyone who gets in our way." Victor finished. "Can you do that, little brother?" James watched his older siblings for a moment before he nodded his head.

"They're coming." Katherine said as she looked towards the voices and lights coming towards them.

"Can you run?" Victor asked James, who nodded his answer. The three of them took off through the trees.

"Keep on running, don't look back." Victor said as they jumped over roots and weaved around threes. Katherine knew from that point… her life as well as the lives of her brothers was never going to be the same again.

Katherine never imaged war being in her future. Once Victor, James, and herself had gotten away from the people coming to get them for killing their father, they spent years in wars. She'd discovered that on top of her elemental powers that she, like her brothers, had an accelerated healing factor as well as heightened scenes. The three of them had seen multiple wars and during the Korean War, when Victor decided to kill a commanding officer, it had landed them in a military prison. Their execution was supposed to be by firing squad… with the healing factor, one can imagine how that turned out. A few weeks later, the door was opened, blinding the siblings momentarily. A man was standing in front of them; he was in an army uniform, decorated with all different kinds of metals. "My name is Major William Stryker. You've been charged with killing a senior officer. Is that correct?"

"Apparently, we have some issues with authority…" Victor said in a low voice.

"Just keep a lid on it." James said to him.

"…sir." Victor said with sarcasm dripping from his voice. This caused Katherine to chuckle.

"The warden tells me that your sentence was carried out by a firing squad at 1000 hours. How'd that go?" Stryker asked them.

"It tickled." Katherine said, leaning her head against the wall behind her, watching the man closely. She reached up, brushing some of her short hair out of her face. She'd been disguised as a man for the longest time so that she could fight on the frontline with Victor and James. Stryker smiled before pulling off his sunglasses.

"Are you tired of running? Tired of denying your true nature?" Stryker asked, taking small steps towards the siblings.

"What do you care?" Victor asked.

"Oh, I care. I care because I know how special you are. How valuable." Stryker kneeled down. "Look, you can stay here locked up like freaks of nature, or you can join me." This caught their attention. "I'm putting together a special team with special privileges." Victor glanced at Katherine and Logan, who did the same before looking at each other. "Now tell me, how would you like to really serve your country?"

Katherine rubbed her hand along James' back. She knew without him saying anything that he was getting airsick. She glanced at the men around her. They were all a part of this special team… they were all mutants. She'd actually become close to a few of them. The one sharpening his blades in front of her… she could sometimes live without however.

"You know, I love this weapon more than any other thing in the whole world. Do you wanna know why?" Wade Wilson, the Merc with the Mouth, said to Victor as he leaned forward, holding the sword in his hands.

"No." Victor answered simply.

"It's memorable." Wade said, looking up at him. Katherine turned to him and raised an eyebrow.

"How so?" She asked. He turned his attention to her and smirked.

"Well doll," Victor growled lightly, a warning. "You whip out a couple of swords at your ex-girlfriend's wedding; they will never, ever forget it."

"That's funny, Wade." Victor said with a small smirk on his face. "I think you confuse me with someone who gives a shit." Wade scoffs as he leans back.

"Right, it's probably not as intimidating as having a gun or bone claws or elemental powers or the fingernails of a bag lady." Wade said as he looked around the plane at each person he mentioned. Katherine glanced down, watching Victor's claws expand. Wade glanced down as well, one of his hands moving to the hilt of his sword while the other holding up a grindstone. "Manicure?" That caused Katherine to actually smile.

"Victor, easy." James said to him when he noticed the claws extended. Victor was smirking at the Merc, Wade watched him for a moment before he decided to change the subject.

"Fred got a new tattoo. I'm concerned." James and Katherine turned to the bigger man sitting next to them. It was a tattoo of a woman in a pin-up position.

"Oh, Jesus, Fred, you just met her last night." James said as he leaned back to get a better look at the tattoo.

"I love her." Fred said back simply.

"You love her after one night?" James asked, a look of disbelief on his face.

"She's a gymnast." Fred said, causing Katherine and Bradley to smile.

"Bradley, take her down." Stryker said to the man before he used his powers to cause the plane to descend. As the plane began to move downwards, James groaned and immediately assumed the position he was in moments ago.

"Are you gonna puke?" Fred asked as he ate another bite of his protein bar.

"If we were meant to fly, we'd have wings." James said without looking up.

"Aw, don't worry, Nancy. More people die driving than flying." Agent Zero said to James. Katherine turned to him and glared.

"Really Zero? How about burning?" She asked, her free hand (the hand not rubbing James' back) catching fire. Zero kept his gaze steady with hers, keeping his emotionless expression.

"Hey, be nice." John Wraith said to her. He'd become one of her closest friends on the team, along with Fred, Bradley, and as much as she hated to admit it Wade. "Or be your approximation of nice." Katherine let a small smile grace her features as she turned back to John. The man turned his attention to James, a small smile on his face. "Would you like a bucket?"

"No." James said, shaking his head softly.

"Wheels down in Lagos in five." Stryker said. Katherine couldn't help but realize how much of a turn her life had taken from the time she'd been a child, just learning about her powers until now.

"Tell him this rock is more valuable to me than his life. Ask him where he found it." Stryker said to Wade so that he could translate. Katherine stood beside James, trying to figure things out. They'd just busted up a huge diamond ring to only take a "souvenir" that Stryker wouldn't tell them what he wanted it for. She could smell the metal from where she was standing, it was like nothing she'd ever smelt before and she prided herself on her senses being higher than even her brothers.

"He says it came from the sky." Wade said back after he'd translated.

"He's telling the truth." James said from beside her.

"You don't know the language, Logan." Stryker said to the man with a smirk on his face. The fires around them began to burn brighter, Katherine was making it known in a nice way she didn't like the jab Stryker had taken at James with using his supposed biological last name. Stryker glanced at her, his eyes narrowing slightly before he turned them back to James.

"It's a meteor fragment." He finished his thought, ignoring Stryker's comment.

"I know what it is. I'm asking him where he found it." Stryker said.

"Sir, base wants to know our location." Bradley said from behind the group. He'd always been a smaller man, not much for fighting like the rest of them.

"Shut them down." Stryker replied. Bradley nodded his head, closing his eyes for a moment to shut off the connection.

"Tell him everyone here will die unless he tells me where he found the rock." Stryker said, causing Katherine to look up in shock. Over time, the killing had begun to get old. She would rather not do it anymore but it was what kept her brothers together and by her side. Her eyes strayed to Victor, who stood a few steps off to the side of Stryker. He was watching the man before he turned his eyes to her. He wasn't Victor anymore. He wasn't their big brother. He had been consumed by whatever monster had made their way into him. Katherine knew it and she was pretty sure James knew as well. She glanced at Wade, he was wearing a similar expression but she wouldn't expect anything less from the mercenary. Wade sighed before translating what the man had just told him.

"He says that it's sacred."

"Okay, fine." Stryker said before standing up, walking over to Victor, laying a hand on his shoulder. Katherine watched in silence, tilting her head slightly. Her brother took a step forward, grabbing the man by the back of the neck, breaking it easily. Some of the people got up and ran, Zero opened fire only to be tackled to the ground by James. Victor and Wade were taking people out left and right.

"VICTOR!" James called out to their brother before getting up running to stop him. Katherine turned her attention to Wade, running to stop him before he killed a woman with a child. She stepped between them at the last second, taking one of Wade's swords through the left side of her abdomen; she gripped the wrist holding onto the hilt of the sword. The mercenary stood stark still, looking at the woman in surprise. She coughed, some blood dripping down her chin as she looked up at the man before turning her attention to Victor and James. Her brothers glanced around at the rest of the team, only to stop when they saw Katherine impaled by one of Wade's swords. She pushed the man back, covering the wound as it began to heal. Katherine made her way to her brothers.

"This is what we do." She heard Victor whisper to James. "Maybe you and Kathy would rather be rotting in a whole somewhere till they figure out a way to do it to us. Is that is?"

"I'm done." James said, ignoring Victor's comment.

"Me too." She said, glancing down at the wound, seeing it was almost all the way closed up.

"You coming?" James asked him. There was a moment of stillness between them before James turned and walked away. Katherine spared one more glance at her older brother before she followed James' lead.

"Jimmy! Kathy!" Victor called to them, causing then to stop and turn to face him. "We can't just let you walk away." Katherine watched as James' reached up and pulled his dog tags from around his neck and threw them towards Victor. Katherine reached up and did the same. "Jimmy!" He called but got no response. "Kathy!" Again, no response. The team stood silently as the pair of them walked out of sight into the forest. It hurt her just a bit. Leaving her big brother behind but she knew he wasn't their brother anymore. She didn't want to kill, even if it kept them together all of these years, she didn't want to kill anymore. She glanced up at James, where were they going to go now?

"Alright, class dismissed." Katherine said as she packed up her materials. The kids left quickly, making their way out and either to their rooms or their next class. The woman had been here witch Charles Xavier in Westchester, New York for a number of years, at first she was here to learn to control her powers (which didn't take long) and then he offered her a teaching position, which she accepted. She loved the man and she loved what he was doing for the young mutants of the world. She had just finished putting everything into her bag when she got a telepathic message from the professor that she was needed in his office to show someone around. She grabbed her bag and began down the hall. She jogged down the hall when she saw Scott and Ororo enter the office.

She slipped in before Scott, smiling at him before throwing her bag down beside the doors. She looked up and it felt like her heart stopped. Standing in front of her was her little brother, James Howlett. He was looking around confused like he didn't even recognize her.

"Ah, Logan, I would like you to meet Ororo Monroe also called Storm and this is Scott Summers also called Cyclops. And lastly, this is Katherine Howlett also known as Mother Nature." She watched as Scott offered his hand to the man but "Logan" never took his eyes off of her.

"Do I know you?" He asked, tilting his head to the side.

"That depends." She said, pushing her hands into her jean pockets. "What do you think you remember about me?"

"I remember a little girl, older than me. She looked like you. Her name started with a K." The woman couldn't help but smile.

"Yeah, that was me. I'm your older sister Logan." The man's eyes widen in surprise as he took in the news.

"You are?" She nodded her head but didn't move towards him. It seemed like he didn't have any memory so he may not even trust her fully. She just would have to take her time and let him remember everything on his own, before she could say anything else; Jean came into the room then.

"I believe you've already met Dr. Jean Grey." The professor said, drawing Logan's attention from her to the redheaded woman that had entered the room. "You're in my school for the gifted. Mutants, you are safe here from Magento."

"What's a Magneto?" Logan asked him.

"A very powerful mutant who believes that a war is brewing between mutants and the rest of humanity. I've been following his activities for some time now. The man that attacked you is an associate of his called Sabretooth." Katherine tensed at the name but tried to relax before anyone saw it. Logan turned to Storm.

"Storm?" He then turned to Katherine. "Mother Nature?" He clicked his tongue causing her to raise an eyebrow. "And what do they call you? Wheels?" He asked chuckling before turning to leave, noticing Scott hadn't moved. "Cyclops right?" Logan asked before reaching out and grabbing the man by the collar. "You wanna get out of my way?" Katherine stepped between them, pushing Scott away from Logan. Her brother looked down at her, as if remembering something. Charles voice drew his attention.

"Logan, it's been almost fifteen years, hasn't it? Living from day to day, moving from place to place with no memory of who or what you are." Logan turned to the man quickly.

"Shut up." Katherine took a step back before stepping by Logan's side, in case she had to stop him. She wasn't sure how much he'd changed in the last twenty-one years since she'd seen him.

"Give me a chance. I may be able to help you find some answers and even if I can't… Katherine can." Logan glanced at her before turning back to Charles.

"How do you know?" Charles said something to him telepathically because he began to look around frantically. He turned his gaze back to the professor before smirking.

"What is this place?" He asked. Katherine and Charles gave Logan the tour, stopping to watch Rogue interact with some of the other kids. She smiled slightly when she saw John Allerdyce take his lighter and make a fireball behind his back. He was trying to impress Rogue.

"I thought you took his lighter away?" Charles asked her with a knowing smile. Katherine put her hands in her jean pockets and rocked back on her heels slightly.

"What can I say? I know how much fun it is to control fire." Charles chuckled before turning back to the scene. Bobby Drake then reached out, using his ice powers to freeze the fire. It dropped from John's hand onto the ground, shattering. This grabbed Storm's attention, which she scolded the boy with a tone before turning back to the lesson. Bobby then began to talk to Rogue before making an ice rose for her. The tour continued and the professor made a deal with Logan that he'd accepted. He would stay and let the Professor and Katherine try to help him figure out his past and remain at the institute, safe from Magneto. Katherine stood up from her seat in his office, placing a kiss on the top of Logan's head. "Good to have you back Jimmy." She said before she walked down the hall to her next class. Her brother was back, safe and sound with her. Nothing could make it any better.
