DISCLAIMER: I do not own X-men Evolution or Bishoujo Senshi Sailor Moon. I only own this plot that I made up.

BETTER SUMMARY: The X-men Evolution and Sailor Moon dimensions have *purposely* collided. The Sailor Soldiers are finished with Chaos. So what happens when the evil Mesmero goes out of his way to steal one of Sailor Pluto's time keys? Why does Xavier offer the girls to join the X-men? Since when were the Sailor Soldiers ever mutants? Find out in this fanfic of romance, action, drama, humor, and crossing over!

A/N: X-men/Sailor Moon Crossover. Pairings will be a special surprise. I'll only give you two as a hint though (one is an X-men couple and the other is a Sailor Moon couple) = SS/JG and UT/MC. Most of you probably know these two couples but I don't want to spoil the other ones. I'll even throw in some love triangles just to make some mischief! It's just more fun that way.

The X-men plot takes place right after the second season. The Sailor Moon plot is finished. I am using the anime version of Sailor Moon for this fic. Don't be confused by the manga! I'm warning you now. I will be using Japanese names because I think they sound cooler, in my opinion of course. There will be at least two different POVs for every chapter. It may start off a bit boring at first but the story will eventually pick up. Just be patient!

Special fanfic appearances by: Archangel, Havok, the Outer Senshi, Chibi-Usa, the Amazoness Quartet, and the return of the Sailor Star Lights! This fic does NOT include Princess Kakyuu.

That's all I wanted to say now enjoy the fic!

Evolution Borders the Moon

By Angel Priestess

Chapter 1: A message for the Lady in Red

CHERRY HILL TEMPLE, JAPAN

Rei Hino, Shinto priestess in training of her elder grandfather's temple; nonetheless she has promised herself to follow the legacy of her family's tradition. This young, fiery spirit has mastered the art of reading fire and having it warn her about the evils around her. Does it tell her everything? No. But in this sacred tradition of reading fire, she has learned to trust its precautions and answers…

Ah, yes. The sailor soldier of flame awakens to a new day in her pajamas from her small mattress lying on the temple floor. Yawning, she heads toward the bathroom to do her "hygienic business." After coming out, she is already changed into her priestess outfit ready to meditate as she has done in her normal daily routine for the past few years.

Before settling down in front of the fire, she sees Yuuichirou working hard on sweeping the floors and stairwell leading up to the temple. His shaggy brown hair hung in the front like it normally did, his scruffy facial hair, his loose-fitted Shinto outfit – the boy was still the same even after almost two years of being with her. She's felt like she's known him forever. Although he may have seemed like a dope to most people, to her, it was one her best friends that she could always count on to be honest with her. It killed her sometimes to hurt his feelings the way that she does. She only wished he could understand how she felt toward him when he irritated her or made her upset.

Yuuichirou and her wouldn't really be called a couple according to 'her' standards. Yuuichirou is constantly confused if they are a couple or not. Everyone laughs and jokes about it, especially Usagi, but Rei always seemed aggravated whenever he mentioned that they were together. He's one of the only boys she really hangs out with, true. They see each other practically everyday. He's always doing nice things for her with good intentions, which she does truly appreciate, yes. They talk to each other sometimes more than she talks with the other sailors, also true. But she never thought beyond the limits of friendship with Yuuichirou. Yeah, he's cute, sweet, respectful, and he's one of the only boys who'll probably ever get along with Grandpa. She growled at the thought for a moment being angry with both him and herself at the same time.

Yuuichirou tries real hard to fit in at the temple. Sometimes she's too blind to actually see how much the poor boy is really trying. She does feel guilty but of course, she doesn't show it or let it get to her. She wanted him to stay there forever with her and Grandpa. It was great and it was one of the most peaceful times she's ever experienced. Sometimes she hated being a soldier, but she understood the responsibility and the need for action. It was already part of her life now. She couldn't change that, no way, no how.

Those thoughts don't bother her as much as they used to anymore however. After nearly two years of being a sailor soldier, she's learned to cope with the stress and responsibilities at hand. That wasn't the problem. They had already defeated Chaos. Evil didn't seem like much of a threat anymore. She still felt it lingering there though. Evil was never defeated and it may never will. That was okay. That wasn't the problem. Sometimes she enjoyed fighting. In fact, she loved it! It was one of the best parts of being a sailor soldier – the adrenaline, the powers, her fighting moves… That wasn't the problem either. Yuuichirou wasn't the problem. They were both big parts of her life.

So what is the problem? Peace. Peace was too peaceful, too quiet and somehow she felt that there was evil going on that she still couldn't defeat. Its presence was unclear. But she knew it was there. She felt it in her bones, her soul. Something was out there that she felt needed the sailor soldiers. But she wasn't even sure if it was just another one of her hunches.

What if she just needed to unwind her powers a little bit so to keep intact with her other alias, Sailor Mars? Was that it? She wanted to feel a little rush so she could continue being Sailor Mars instead of just the plain, Shinto priestess Rei Hino? No. Of course she misses being Sailor Mars. She knew that evil lurked in the other shadows of planet Earth, but was it really her responsibility now? All evil to her felt like her responsibility. Think about it this way, she's already gone and defeated what she thought were supposed to be the villains of villains – Queen Beryl, The Doom Phantom, the Kisenian flower, Badiyanu, Princess Snow Kaguya, Mistress Nine, Pharaoh 90, Nephrenia, and Chaos.

Rei Hino

What else is out there, she thought to herself? Being a Shinto priestess was my dream, no doubt about that. So, why am I complaining? Peace is wonderful! Why should I spoil one of the best opportunities I have of finally being able to enjoy myself? When evil comes, the fires will let me know. Whatever my destiny is from here, I'll be waiting.

With that, it was, "Good morning, Yuuichirou!" He looked surprised when I had called him but quickly turned into a light blush and smiled.

"Morning, Rei! I'm just cleaning up so could do your fire summoning thing." I shook my head at his attempt to define the art of reading fire. I smirked and explained the ritual of reading fire to him very, very slowly.

"And that's pretty much the basics of it!" I ended. Yuuichirou looked absolutely dumbfounded. I couldn't blame him. It was a hard subject to study – Shinto that it. Fire reading and meditating were definitely a big part of it. No one understands it on the first explanation. Yuuichirou was just someone you had to explain twice to about almost everything. It didn't bother me anymore as much as it used to. We've grown a lot since then and we both understand each other a lot better now.

"Thanks for cleaning the fireplace for me, Yuuichirou. Could you do me a favor while I'm meditating?"

"Uh, sure Rei! Anything you want, what can I do for you?" He was so goofy sometimes, I thought.

"Could you pick up some herbs for me in the supermarket? I need them later on for a special mixture I'm making. For supper tonight, I think I'm going to make something nice for Grandpa. So, here's the money and the list of herbs, spices, and ingredients. Be back with it soon. I need to make this early. Now go!"

"You got it Rei!" With an army salute, he ran off like the little dork he is, but he was a cute dork. I shook my head as he darted down the street.

I walked into my meditating area and began the chanting slowly, using my hands to create symbols to summon the fire to answer my question of fate. The fire cracked and lit up in a blaze. I continued chanting and fed the fire some homegrown twigs that we grew in the garden. My chanting eased softer now and I concentrated hard on reading. I closed my eyes now to concentrate even harder on the fire.

I whispered, "Oh Great Spirit, tell me, what path lies ahead for the sailor soldier of Mars?" The fire blazed higher and faster now, whipping its curved lines into the shape of a picture. The picture formed into some kind of jet. A jet? What did that mean? The jet in the picture approached closer as if it were about to come and lash out at me. The jet was noisy and frightening. It was coming closer and closer! The jet was huge by now. The noise was deafening. I shrieked in fear as I felt the fire come out in the shape of the jet. It sent me back falling hard on my backside to get away from the flying jet. But the fire did not reach as far as I thought it would. Instead, it broke apart as it came closer to me and returned into the normal state that it was originally in as the plain curved lines. I breathed heavily, gasping hard. A small amount of sweat was dripping on my face. What was that? A metal noise then shackled the room since the walls were secured by metal screws and nails. Then, a *SNIKT* sound invaded the room. The sounds then disappeared.

I looked at the fire oddly. It's never done anything like that before. It's never been so interactive like that. But what could it mean? I didn't really see anyone flying the jet but there might've been somebody inside. I couldn't tell. I should've been paying closer attention. Damn! I slammed my fist hard on the tile floor beneath my slacking body. I was a little afraid to contact it again. Maybe I'll do it later on tonight and call the soldiers over to see if they know anything.

Wow, that was pretty intense. My body was still a bit shook. I've never seen anything like that before. It was definitely not an ordinary jet. Was it just my path, though? What are you trying to tell me, Great Spirit?

I decided it'd be best to end my fire reading session there and continue it later on tonight when the other sailors could be here with me. I called Usagi first, and asked if she'd call the others so we could discuss the fire reading I received at my temple. The feeling in the pit of my stomach told me this wasn't a good sign. Maybe it's not time-out for the sailor soldiers just yet. Our duties aren't finished. I just hope we know what we're dealing with.

Or maybe, I should stop playing with fire…

XAVIER INSTITUTE FOR GIFTED YOUNGSTERS, WESTCHESTER, NEW YORK

"Ororo, Logan, Scott, Jean, come with me," the Professor said as he directed them to Cerebro. "We must continue searching for new mutants. I need them to stay undiscovered until we can make the humans understand the mutant structure. It's too early to make them aware of mutants like us. They won't understand, not yet at least."

"You know, Charles," Logan commented, "I get the feeling that we're just going to end up babysitting more of these little whiners. Sometimes I honestly don't know how you stand it." Xavier chuckled. Scott and Jean gave him a look.

"The children are here to learn, Logan. They are here to discover, learn, and control. If any one of those limits go out of line, I'm afraid our mutant cover will be revealed. I hope that it will not break out just yet. We still need more information." A beeping noise came from Cerebro as Professor fidgeted with the gadgets and buttons. "Hmm, it seems as if Cerebro has detected two new mutant signatures in the region of… Japan? My, it seems as if these two mutants have been using their powers long before even Cerebro was developed. Both are female, and they live in the same area. Ami Mizuno, age 16, an extraordinary I.Q. of… 300! She's the nation's top high school student! Amazing!" Scott and Jean were awed. Ororo narrowed her eyes for a minute and wondered. "The other mutant signature detected is this young lady." He pointed at the screen to a raven-haired girl with purple eyes. "This one can read fire like the common Shinto priestess but she can also control the fire much like a fortuneteller. Her name is Rei Hino. She's 16 as well. These two girls have been seen using their powers for years now. All of us will head to Japan in the X-Jet immediately and see if these girls are in any hazardous danger. If they are, we'll recover them. They speak little English but I'll try to communicate with them telepathically if necessary."

As he wheeled out of the Cerebro room with Logan, Scott, Jean, and Ororo, he expectedly sensed three other mutants crowded in front of the Cerebro entrance whispering to each other. Ororo cleared her throat as she opened the automatic door to find Rogue, Kitty, and Kurt talking to each other about Japan and the new mutants. Logan raised an eyebrow at them.

"Sorry kids, this ain't going to be a field trip."

"But, Mr. Logan, how come they get to go?" She asked pointing in Scott and Jean's direction.

Before he could respond, Charles interrupted him, "We're heading overseas to recover any new mutants. It's only a possibility however. We just want to talk with two in which Cerebro detected. This isn't a rescue mission, yet.

"Scott and Jean are the student mentors of this Institute. They're in training to become teachers here to help everyone in any danger as much as possible. They will need to practice how to convince dangerous mutants to become part of the X-men. If these two new mutants are dangerous, then I will feel more comfortable if Jean and Scott are handling the situation. They've had more experience than you three have. We're giving the mutants, that Cerebro detected, a choice if they'd even like to join the X-men."

"So, vhat exactly are zare powerz? Are zhey anyzhing like zhe fuzzy dude?" Kurt asked with a look of excitement clearly written on his face.

"That's classified information, Kurt. If they decide to come here, I'll definitely let you know the details along with the rest of the X-men. Head back to your bedrooms now and get some sleep. You have school in the morning."

All three sighed at the same time and bowed their heads in surrender. They all hunched and looked at the floor. Turning to head to their bedrooms, they nodded in response, "Yes, Professor."

After their bodies disappeared out of the hallway leading to Cerebro Logan added some feedback. "You've definitely got them in line, Charles," he said with a smirk.

"Indeed. Now, we must report immediately to Japan. It'll be nighttime by the time we get overseas there."

"Man! Scott an' Jean always get assigned to go to tha far areas in tha recruitin' missions! Sometimes I think the Professor has them as his favorites. Why are we always stuck here with tha rest of tha dork squad?" She was obviously referring to the rest of the X-men currently working in the Danger Room with Beast.

"Like the Professor said," Kitty started, "we're just not old enough yet. We're like still in high school. Scott and Jean are gonna be graduating pretty soon. Not to mention, Scott's always been like the 'oh so great leader' of the X-men and Jean's always sorta been like his sidekick you know?"

"I zink zhey are getting zoo much credit! Vhat is so dangerouz about recruiting oder mutants? Maybe he doesn't trust uz!" Kurt sniffled in thought.

"Oh Kurt, don't be so melodramatic!" Kitty said. "Maybe if we're good, the Professor will like totally take us on the next recruiting mission!" She smiled at her suggestion. "Hey, maybe just to impress Wolverine and the Professor we can take like double time in the Danger Room after school this week. Then he'll like totally have to take us on the next mission! What do think?"

Rogue snickered at her roommate's valley girl accent. It bothered her sometimes-just sounding like a judgmental airhead. Sometimes she felt sorry for her. The poor girl was clearly misunderstood. And she had a cool power, no doubt. Walking through walls and other stuff – who wouldn't want to do that? But the girl made herself look stupid sometimes. That's what Rogue thought at least. But she knew that Kitty always had good intentions even though she seemed like somewhat of a stuck-up airhead. She was smart, but Rogue knew the girl could pull off a better act than a valley girl.

Kurt didn't really respond to Kitty's suggestion and neither did Rogue. Kurt just groaned and Rogue helplessly stared at the floor as she lay on the coach. "It's just not fair!" Rogue mumbled out. "Scott an' Jean don't have to do any of dat stuff! We're just going to be the ones stuck haulin' tha dirt while they're tha ones flying through tha clouds!" Rogue sighed and headed toward her room with a frown clearly printed on her face. Kurt gave out one last groan and teleported to his room.

Kitty just sat there by herself with her laptop sitting next to her. The one time she had peace and quiet, she couldn't really focus nor have the enthusiasm to type. Japan got her all worked up. Then she wondered to herself, Dr. McCoy is the only chaperone here. He's gonna have his hands full for a little while. He won't notice I'm gone with all the other students that he's gotta take care of… An evil smirk crept upon Kitty's face. An evil idea came into her mind. I could just hijack one of the smaller jets for a little while. Kitty was thinking out loud to herself at this point as a kitten entered the room through the mailbox in the door. "Hey there Kitty! What are doing here?" Kitty said as she stroked the kitten's back sweetly. The kitten smelled nice and… oddly familiar. Kitty turned her head to the side trying to figure it out as the kitten quickly emerged into the figure of a beautiful blue woman – none other than Rogue's former foster mother Mystique. Kitty gasped and was taken aback. Her eyes were wide in fear. She's never gone head on versus Mystique but she wasn't going to let that stop her. Kitty immediately glared at her and phased through the floor.

By now she was already familiar with the Shadowcat's moves. Mystique jumped toward the ceiling and broke all the cameras in sight with a few punches and kicks. When Kitty phased up through the same floor, she saw Mystique nowhere in sight. Before she could get a good look around, Mystique kicked her hard from behind in the area where her neck and back meet. Just to make sure she was to keep her mouth shut, Mystique twisted the girl's head, cracking the bone which would send her into unconsciousness for a good day or two. "Well, it seems like someone needs more training in the Danger Room. Make it a challenge next time, cat." She dragged Kitty's body back in the Med. Wing and threw a blanket over her frail body.

She then morphed into Kitty Pryde and said her last words to Kitty that night, "Although you're persona lacks class, your idea happened to intrigue me. I'll twist it around a little bit and take your word for it. Thanks again, Shadowcat." With that, she patted the girl's cheek, laughed and left.

"Rogue!" She shouted in the hallways. "I just had like the coolest idea! While the Professor's gone, let's like go to Cerebro and check for mutant signatures! If we find them, how about we try to recruit them? But we'll need one of the smaller X-jets. And, if we don't find them we forget the whole 'hijacking' part of the plan and give them like an e-mail or something. What do you think Rogue?" The idea sounded lame to Mystique but it was the only thing to convince Rogue to go with her. She didn't really have a back-up plan.

"Kitty are you okay?"

"Rogue, please? I'm sick of staying at the Institute all the time. Let's just get away for a little while and have some fun. Besides, thing about it, we'll be doing the Professor a favor. He'll have to like give us some credit, please?"

"Kitty…" She gave Rogue a puppy dog pout. Rogue eventually gave in after thinking it completely through.

"Fine, Ah'll come. But if we get in trouble, Ah'm blaming it on you for bribin' me, got it Kitty?" Kitty nodded and screamed in joy.

"Yeah! Like, thanks Rogue!"

Just then, Kurt teleported into the room and immediately asked, "Vhat's going on? I heard you zcreaming."

She was stunned to see how wonderful her long-lost son had turned out. Kurt, she thought to herself. You look great, my son. She quickly snapped out of it and said, "Kurt, I have a proposal for you. Like how about this…" She talked to him about the plan and he agreed with little hesitation. Although he knew the consequences of his actions, he was going to follow Rogue's example and blame it on Kitty when they got in trouble. It's funny, Kitty's first suggestion seemed reasonable but even he could've thought of that. Deep down he knew he was going to end up looking at double sessions of the Danger Room if he wanted to impress Professor Xavier or not. "Come on, let's check Cerebro now and see what mutants are 'active' as the Professor puts it." The three mischief-makers headed like spies toward Cerebro.

"Vhy do I all of a zudden veel like zhis iz not a good izea." Kurt said to himself rubbing the back of his head nervously and sighed.

"Don't worry Blue, Ah feel tha exact same way you do." Rogue managed to whisper behind Kurt as Kitty skipped down the hallways toward the staircase leading to Cerebro. "Ah didn't think someone like Kitty would be this mischievous. She's not usually this psycho. If you ask me, ah could've been the one to think up of a plan like this. Doesn't she know better? What's going on with 'er?"

"I zon't know. Maybe she'z just excited, zhat's all."

"Maybe. It's a little bit too weird if you ask me. Ah've ne'er seem 'er like this before."

"Neider have I. But ve gotz our backup plan, yes?" Rogue nodded hesitantly. If you say so Kurt.
