Some people may know me as a big fan of Toaru Majutsu no Index, but I like a lot of other things too. One of those things is Pokémon. My friends and I argue a lot about which Pokémon is the best and they do not understand that Eevee is the best one. Anyways, I always wanted to do a crossover between Index and Pokémon, hence this story. I do not have experience in the Aloha region, so do not expect Pokémon from there. Now, this follows the characters from Toaru Majutsu no Index in the Pokémon world, so if you have no read Index, you will be confused. This story is not following the main characters from Pokémon. I wanted to add this disclaimer because I know some people might get the wrong first impression.

This is my first crossover and I hope you all enjoy it. As this is a side project, it will not have a set release schedule. I write it in between of my main stories when I'm in a rut or need a break.

Disclaimer: I do not own Toaru Majutsu no Index or Pokémon. I wish I did so I can retire rich.

The Nelos region was an unusual location in the world full of strange creatures known as Pokémon, creatures that have lived side by side with humans as long as anyone could remember. Many regions existed in the world and each one had Pokémon unique only to them. The reason the Nelos region was so special was because it was an area Pokémon had gathered from all over the rest of the world. Due to this unusual phenomenon, several Pokémon research centers had set up laboratories to study the history of the uncharted region, along with the Pokémon that inhabited it. Once they had established a small town, trainers from all over the world started to arrive to catch and train Pokémon they normally would have never encounter. The surge of people wanting to travel to the new region caused many businesses to set up shop and the once small research outpost become a large and thriving costal city.

The first city became known as Academy City.

This metropolis not only contained some of the most advance research in the world, but also some of the largest Pokémon schools. With the large number of people moving into the city, a lot of young children, who were not old enough to go out into the world, also arrived. They attended school to learn the skills they desired to achieve their dreams. Some wanted to become Pokémon trainers, some wanted to become scientists, and many others wanted to travel down a completely different path. Even though they could not become trainers yet, once they reached a certain age, they could choose from one of dozens of starters Pokémon. This was to give them an idea on what Pokémon were like and allowed them a chance to start raising their own under careful supervision. Since the city was connected to all the other regions, the students had a much larger variety of starters to choose from. One girl was even able to choose a rare Pokémon that many did not get a chance to see.

This girl was also not in class, but had skipped her lessons to venture into the nearby forest.

"Whew," the girl mumbled and wiped the sweat from her brow. The girl had short chestnut colored hair, held in place with a small hairclip, decorated with two flowers, on her right side and looked to be around fourteen years old. She was wearing a pair of brown shorts, a black t-shirt, a white baseball hat, and a green backpack. Her name was Mikoto Misaka and she was a student of Academy City. She sat down on a log and looked out across the open field. She was right on the border of the forest and was taking a slight break. A couple Tranquills and Fletchlings, small bird Pokémon, were flying above her in the nice sunny day. A couple Poochyena, small grey canine Pokémon, were playing around and chasing each other. Several different bug types were crawling around in the trees behind her, but did not disturb her. It was peaceful compared to the hustle and bustle of the city. "I think we deserve a break, right Pikachu?"

"Pika!" the small Pokémon next to her said. Pikachu was a short, yellow rodent Pokémon. It was covered in yellow fur with two horizontal brown stripes on its back. It had a small mouth, long, pointed ears with black tips, brown eyes, and two red circles on its cheeks. The pouches inside its cheeks stored electricity and occasionally gave off small sparks. It has short forearms with five fingers on each paw, and its feet each had three toes. At the base of its lightning bolt-shaped tail was patch of brown fur at the base. Mikoto loved electric Pokémon and as soon as she saw Pikachu was a choice for her starter, she immediately chose it.

"How about a quick snack?" Mikoto suggested and pulled out a small bag from her backpack. Pikachu's ears twitched and it jumped up onto the log next to her. "Just one though." She passed over a brightly colored berry and Pikachu grabbed it instantly, bit into it, and looked like it was in heaven. "Heh, you are too cute." While Pikachu was eating, Mikoto thought about what she wanted to do. The reason she skipped class was because she had heard a rumor that a couple of Pokémon she wanted to catch were sighted in the vicinity recently, Plusle and Minun. Mikoto couldn't be entirely sure if the rumors were true, but she couldn't afford to wait. Every day increased the chances they would move on.

The sound of someone screaming snapped her back to reality. She bolted up to her feet and look around wildly for the source.

"Pikachu!" Pikachu yelled out in alarmed.

"I heard it!" Mikoto cried. "There, look!" She pointed in the distance where a dust cloud was coming from. She squinted her eyes and saw two figures running in front of the cloud as fast as they could go. One was a human male with spikey black hair, who was probably only a year or two older than her. A Pokémon, who Mikoto assumed was the boy's, was running next to him... She had never seen that particular Pokémon before. It was a large, bipedal dark-gray dinosaur-like Pokémon. It had a blue dome head, which obstructed its red eyes, and blue stripes, with one on its tail and one on each of its knees and wrists. Various spikes covered its body, one on each knee, two on the blue collar on its neck, two short ones on its nose, and four on its head. Two of these head spikes are bigger than the other two. Mikoto was about to pull out her Pokedex, a small handheld device that identified Pokémon, when she heard the boy crying out in panic to the dust cloud.

"I'm sorry!" the boy was yelling over his shoulder. "We didn't mean to upset you! Rampardos gets a little eager!"

"Rampard!" Based on its tone, Rampardos did not sound like it was sorry. It actually sounded like it was having fun, despite the situation. They started to close in on Mikoto and Pikachu, when Mikoto realized what the boy was running from.

The boy was being chased by at least twenty Rhyhorns.

Rhyhorns were rhinoceros-like creature with their bodies covered in gray, rocky plates. Its underside and rear were smooth, and it had four short legs with two claws on each foot. It had a triangular head with narrow, red eyes, two fangs protruding from its upper jaw, and small, triangular openings on the upper sides. A spiked ridge ran along its back, and it had a single short horn on the tip of its snout. In addition to its rocky hide, its bones were a thousand times harder than human bones. Whatever the boy and his Pokémon did to anger them, a Rhyhorn stampede would crush them flatter than a pancake. Mikoto wasn't sure if they would get out of that situation, but then she noticed another problem.

The boy was running right at her!

The boy finally noticed her and waved to grab her attention. "HEY! Retreat into the woods! They can't follow us once the trees get to thick!" Mikoto's mouth fell open at the sheer stupidity of this predicament, until a tug on her leg brought her back to her senses. Pikachu was tugging on her leg to get her to move out of the way. She blinked, turned around, and ran into the woods with Pikachu, as the boy and his Pokémon followed right behind her. All of them slipped through trees and slid down an incline as fast as they could. They heard the heavy thuds of the Rhyhorns' footprints get softer and softer until they disappeared into the distance. The Rhyhorns must have swerved to the side instead of smashing through the trees. When Mikoto and the boy were sure they were safe from being crushed, they stopped to catch their breath. Mikoto looked up at the boy and glared angrily.

"What was that about?"! she demanded, as she pulled out her red handheld Pokedex. Mikoto held it up to the boy's Pokémon and the screen flashed its picture. She had not forgotten she wanted to know what the boy's Pokémon was.

"Rampardos," the Pokedex said in its mechanical voice. "The Head Butt Pokémon, and the evolved form of Cranidos. Its Headbutt attack is so powerful that it can pulverize even the sturdiest of objects with one hit."

"Sorry about that," the boy apologized to her. "Rampardos gets full of energy when we are stuck in the city for too long, so we have to come out here periodically to blow some of it off. We use all the boulders near the river to practice his Headbutt. He got a little overexcited and accidently hit one of the Rhyhorns."

"What happened then?" Mikoto asked, unable to prevent a slight smirk on her face.

"The Rhyhorn went flying about twenty feet…"

"Rampardos!" Rampardos added in an almost bragging tone.

"…then my bad luck kicked in and that particular Rhyhorn must have been the leader of the group. All the other ones turned on us and we ran for our lives." He sighed. "Such misfortune." Mikoto blinked.

"Regardless," Mikoto replied. "How could you have been so stupid to direct a stampede at someone? We could have been hurt." She gestured to her Pikachu, who had crossed its arm and nodded.

"I'm sorry," the boy apologized again and clasped his hands together in front of him. "I didn't see you until it was too late. I would never purposely put a little girl in harm's way."

"Little girl?" Mikoto replied slowly and unconsciously put a hand on her chest. The boy couldn't have known how she would have taken those words. The boy obviously meant a girl younger than him, but Mikoto took it to mean something else entirely. Mikoto was not developing as fast as other girls her age and it was annoying, especially when one other girl kept rubbing it in her face. Having a random boy say something like that caused a vein to throb in her head. "Pikachu?" Pikachu tilted its head. "Thunder shock."

"W-what?" the boy stammered in surprise, but it was too late. Pikachu started to spark from its cheeks before it leaped into the air.

"PI…KA…CHUUU!" Yellow electricity surrounded Pikachu and flew at the boy.

"AHH!" he yelled and ducked under the blast. The electricity flew over his head and into the forest. "What was that for?!" he demanded as Rampardos moved in front of him. Rampardos growled at Mikoto and Pikachu. Pikachu landed on the ground and continued to spark up. Both Pokémon were prepared for a fight.

"You called me little!"

"You're younger than me though!"

"That doesn't matter!" Mikoto suddenly realized the boy didn't know who she was. Mikoto was considered somewhat of a prodigy in her class. Smart and talented, her scores in both practical and theoretical tests had been way above the others. She had been the first one to catch a wild Pokémon and she could memorize countless strategies to use for any situation. While others treated her like a celebrity, she didn't think she was one. Passing tests in a controlled environment is one thing, but being out here is another. I probably could have thought of several things to do against that stampede in class, but I was in shock when I actually witness it. It's kind of refreshing to be talked to like a normal person. "Think about what you say-…" She was cut off as a loud roar echoed across the forest and several birds took off. Whatever made that noise was close by and did not sound happy. The sound of brush being scrapped aside was heard a second before a large bear stepped out from behind a tree. Its broad body was covered in brown fur, except its muzzle, inner ears, and paw pads, which were a light tan. It has narrow eyes, a triangular, black nose, and wide mouth with small, visible fangs in the upper jaw. A large yellow circle was painted on its chest.

It was an Ursaring.

The students of Academy City had been warned about Ursarings in class. They were extremely territorial and aggressive. Occasionally, one would wonder close to the city and some of the more experience trainers would chase them off or capture them. If they were to encounter one during their trips outside, they were supposed to report it immediately and never approach it. Ursarings were very strong physically and their claws could cut down trees. Mikoto's face paled and so did the boy's. This one was a little larger than previous ones and its shoulder looked slightly burnt. She realized what happened and why its face was full of anger.

Pikachu's Thunder Shock had hit it while it was napping.

"Pikachu!" Mikoto yelled out. "Electro Ball!" Pikachu jumped up into the air and summersaulted as a yellow ball of electricity formed at the end of its tail. It grew larger and Pikachu threw it directly at the Ursaring. Ursaring's claws started to glow and it slashed at the ball, cutting it in half. There was a small explosion, but Ursaring wasn't fazed and did not stop there. It charged forward and its arm glowed a moment before it collided with Pikachu. The force of its arm sent Pikachu flying backwards into a tree with a thud and it slid down to the ground. "Pikachu!" Mikoto cried and rush over. She picked it up and held Pikachu close to her chest. "Are you okay?"

"Pika," Pikachu replied weakly.

"That was Hammer Arm," the boy called out. "It's not playing around. Rampardos," he received a nod in response. "Headbutt!" Rampardos lowered its head and charged. Ursaring's arm begun to glow again, as Ursaring brought it down on Rampardos. The arm and head collided with a loud bang, right before Ursaring's arm was thrown upwards. Rampardos did not stop there and jumped forward to plant its head directly into Ursaring's stomach. Ursaring developed a painful expression on its face, as the air was knocked out of it, and then its feet left the ground. The force of the Headbutt actually lifted Ursaring into the air and threw it backwards. It crashed through a tree, breaking it in half, and slammed into the ground behind some bushes. "Phew," the boy sighed. "Hey, is your Pikachu okay?"

"Yea," Mikoto nodded and looked down. "She's taken a little damage, but should be fine after a short rest." She looked back up. "Is it gone?"

The angry roar answered her question.

"No," the boy answered. "I think we only upset it." Two more trees broke, as the furious Ursaring swung its claws and started marching toward them. "It seems stronger," he added looking at the sliced remains of the tree trunks.

"It must be using Rage," Mikoto told him. "Every time you hit it, its attack is going to rise!" Rage had another effect that the Pokémon who used it would not stop until the battle was over. Unless they knocked it out or ran away, it would keep attacking.

"Well then," the boy said and nodded to Rampardos. "It looks like we are moving to be plan B."

"What's that?" Mikoto asked.

"RUN!" The boy grabbed her hand that was not holding Pikachu and pulled her after him, while Rampardos followed right behind them. They slipped in between the trees, as they tried to lose the rampaging Ursaring crashing through the thicket behind them. It was not planning to let them escape.

"Where are we going?!" Mikoto cried.

"Away from the thing chasing us!" was the boy's only reply. Mikoto now regretted listening to him, but she had to admit it didn't look like they stood a chance against the Ursaring. Mikoto was a newer trainer and the boy didn't appear that much more experienced. In fact, he seemed like an idiot, though he didn't appear to be a bad person. They saw an opening in the trees in the distance and plowed straight toward it. They burst out into the open before hastily coming to a complete stop. Both of them saw the danger ahead of them simultaneously.

They had reached the edge of the cliff.

"It's about thirty feet down," Mikoto informed the boy after glancing over the edge. "There's a river, but I can't tell how deep it is from here."

"So we are stuck?" the boy asked and she sighed.

"Can you fly?" Mikoto asked sarcastically and the boy shook his head. "Then it looks like we are. I can't believe you led us here. If we had run toward the city, it probably wouldn't have followed us."

"Sorry," the boy apologized sincerely and Mikoto sighed. The sound of the Ursaring grew louder as it almost reached them.

"I hope you can fight," Mikoto told him. "Your Rampardos seems pretty strong."

"Pikachu?" Her Pikachu looked up curiously at her.

"You're strong too," Mikoto reassured her.

"Rampardos!" Rampardos looked pleased at the praise. It lowered its head in the direction of the Ursaring.

"Don't get a big head," the boy told his Pokémon. Rampardos nudged him in the side with its tail, but turned back toward the Ursaring who has just emerged from the woods. It looked extremely angry as it glared at them and let out a roar.

"Pika, Pi," Pikachu said as she jumped out of Mikoto's arm. It walked up next to Rampardos and both of them stared at Ursaring. They were ready for a fight. Ursaring lowered its eyes toward them and sneered.

Then it opened its mouth and a sphere of bright white light formed in front of it.

"Is that Hyper Beam?!" Mikoto cried.

"Oh crap!" the boy yelled.

The Ursaring was furious at them and fired the Hyper Beam made of pure energy at their Pokémon. Rampardos and Pikachu managed to dodge to the side, but there was a large explosion when the energy hit the ground. The explosion's force blew them all backwards, over the edge of the cliff, and down into the river below. "AHHHHH!" they yelled as they fell. The Ursaring looked down at them and sneered, before lumbering back into the forest.

Is this karma for skipping class? Mikoto thought to herself right before she hit the river. She wanted to blame the boy, but knew it was partially her fault for her Pikachu's attack. If they made it out of this, she was going to blame him anyways because it made her feel better.
