In a secluded clearing stood a small, stout man observing pale blue lights that danced in the night. The blue lights – unique moonbeams – featured events of the past, present, and future from all over the world, the flock of Swellow, known as his moonbeams, kept an eye out for threats and potential. Four particular events caught his eye, in them were four children that he felt were going to change the world.

As the man walked to one of the four occurrences, the one he focused in on becoming clear and more detailed. The blue lights formed around him to show what looked to be an infant's room. The walls were covered in what looked to be stars randomly decorated about the wall. A pair of doors leading to what looked like a balcony. Roughly near the center of the room was an oval-like, bassinet.

While the short man walked around the bassinet the door swung open revealing a man and woman. The woman was holding an infant with long hair just below her shoulders. The man and woman strode towards the bassinet, rocking the infant gently, seemingly cooing to the baby as she tried to reach for what must be her father.

The mother put the baby in the bassinet, kissing her forehead with a good night, the father following her lead. When the baby closed her eyes, they snuck out the door while turning off the lights and leaving the door ajar.

Immediately, when the lights were darkened, the moonbeams noiselessly shifted to show a cloaked figure entering from the balcony's door. The intruder came towards the unsuspecting infant, a wrinkled, old hand revealing itself from the cloak, grabbing a lock of the child's hair. At first, the man didn't see anything happen, till after a few moments the hair looked to be glowing and the hand becoming wrinkle free. The man couldn't believe what was happening, as the hair still glowed the figure brought out a small dagger. Making a swift cut to the lock of hair, the figure grew outraged as the hair darkened.

Looking at the cloaked figure snatching the child from her sleep and making a mad dash to the balcony, the door across from the figure and child slamming against the wall. When the father saw what was occurring, he rapidly sent out a Gallade with an order to teleport in front of the figure to cut off their escape. The mother threw out a Gardevoir; as the mother sent out a command, the room became a misty haze. The man's vision was obscured by the move he deemed as misty terrain.

When the room cleared, the baby was safe in Gardevoir's grasp; the figure nowhere to be seen. The scene faded away, shifting and forming into something new, as the baby was safely transferred to her mother's arms.

,øººø,øººø,øººø,øººø,øººø,øººø,øºº,

When the moonbeams stopped changing, the man found himself in a forest. There was a good-sized pond, iced over, in his view, a giant boulder frozen within the pond.While he turned around to take in more of the area, three figures emerged from the trees; two were human, a young girl and an older boy with a shepherd staff, and the pokémon Tranquill protectively circling over the duo. The girl immediately got on the ice and started skating, already wearing ice-skates. The boy got onto the ice bare-footed, ice-skates hanging on his shoulder, watching the girl skate around.

The pokémon eyeing the Swellow, though it seemed to be looking at the man, carefully, trying to determine friend or foe. It determined friend as it scanned for any more possible threats. When it deemed it safe, it landed on the ice, hopping around the little girl's feet as she skated around. The young boy didn't look to be older than ten years old, looked around the area as Tranquill had before, though not as intense.

As he started leaning down, carefully taking his ice-skates off his shoulders, when his eyes snapped to the girl. The ice was cracking slowly underneath her skates. The boy made a quick gesture to Tranquill, the pokémon took off – probably to get help – the boy gently placed his skates on the ice. He continued talking when he suddenly jumped on his right foot, towards his staff he must have dropped while the man looked away, dramatically swinging his arms to keep balance. He quickly took two more steps and stooped down swiftly to grab his staff. The boy widened his stance, then beckoned the girl to him.

She took a shaky step forward, cracking the ice further as the girl looked up worriedly towards the older. He beckoned her closer, readying his staff. She tried to take another step when the boy lunged forward, getting the curve of his staff hooked around her waist and pulling her towards solid ground. Things seemed to slow down; the man's eyes opened wide in realization, the girl landed on the ice – sliding for a while – staff following her in her journey, the two smiling and laughing.

The boy took a careless step forward towards the girl, the ice breaking through and the boy falling in. A woman and Tranquill came bursting from the trees, the woman fretfully asking the girl questions. The girl was crying, hugging the boy's staff, pointing to the open water.

A flash of movement caught his attention, getting a glimpse of a ribbon-like tail diving into the open water, refreezing a bit. It didn't go unnoticed by the rest. With bated breath, they waited, after just a moment, there was a brilliant light.

The movement the man saw before was Articuno, a legendary pokémon, the flying pokémon circling the pond in anticipation. The ice parted further revealing the boy, but this boy was different. His hair; his eyes; his skin; was lighter, appearing to be a pale blue to the man observing. The boy looked confused, looking to the woman, the girl, Articuno, and then himself. He looked at his arms and hands, to his bare feet hovering over the ice slightly. As he lowered to the ice, frost sprang from his feet – making a fern-like pattern, spreading outward – and the remaining open water freezing completely over.

He looked startled but walked towards the girl and instinctually grabbed his staff. The girl released it, frost decorating the staff, and immediately leapt into his arms; wrapping her arms around his neck.

Once again, the scene shifted, not explaining what occurred, this time to show an open clearing surrounded by trees. Occupying the clearing was a small family, a little girl with the curliest hair, a giant of a man, and a regal-like woman. They had a picnic set out, the mother delicately ate a sandwich, her husband teaching the girl how to shoot a bow and arrow. The little girl shot an arrow into the surrounding, looking cheerfully to her father, searching for approval. The father smiled at the girl, patting her on the back, and pointing towards the direction the arrow flew to.

The girl smiled, jumping up and down in excitement, nodding, then racing after the arrow. The man looked to the parents, then following in the girl's wake as the mother and father disappeared from the vision as the Swellow followed the girl. The girl was searching high and low for the arrow, she found it stuck in a tree. It was a meter or so high above her head, arrowhead embedded fully into the wood. She placed her bow on the forest floor, grabbing onto a knot in the bark of the tree. Placing her foot onto the gnarled roots, she began climbing to the level of the arrow.

The man saw something from the corner of his peripheral vision, turning to see what it is, his eyes widened. It looked to be the pokémon Ursaring, but bigger, darker furred, scars littering its body, and it was walking on all four legs. The man wanted to warn the child, but knew it was futile; this already happened. As the girl finally pulled out the arrow the Ursaring launched itself at the girl; claws outstretched, maw gaped open. The girl spun around, immediately diving to the side. The tree the girl had just been standing in front of came crashing down, ugly gashes in the fallen trunk.

The child scrambled to her feet, somehow obtaining her bow, and shakily placed her lone arrow to the string of her bow. Releasing it wildly, it stuck itself into the Ursaring's left shoulder. The beast reared tall, its maw opened in a mighty roar, the forest of trees quivering from the force and the girl falling to her back. Ursaring dropping back down on all fours and advanced with bared teeth to the trembling child.

She gripped her bow, and when the beast was a breath away, swung her bow with as much force as possible, the bow breaking on impact. For a second Ursaring paused, then was getting ready to slash at the girl when another pokémon interfered.

The man couldn't register what pokémon it was but saw flames swirling around the pokémon and at Ursaring. After a while, Ursaring retreated, snarling, burnt, and bleeding, into the cover of the trees. The offending pokémon, Entei, stood guard for another attack, then turned to the girl when none came.

The girl stayed sat on the forest floor, looking up at the legendary pokémon in awe. Entei bowed to be eye level, a single, small flame burst to life in front of the girl, the girl looked at the flame, hands reaching for the flame. Just as she was going to touch the flame, she withdrew her arms a smidge, looking to Entei for permission. When the pokémon nodded, she carefully cupped the flame in tiny hands.

Her eyes brightened, a grin growing as she played with it. The flame gradually grew, then disappeared when the child closed her hands. She looked to Entei with wide eyes, he nudged her and created another flame. Just as she was once again taking it into her hands, it disappeared before Entei urged her to do something with a nudge at her arms and hands. Confused, the child stretched her hands outward, palms up, and, with a look of concentration, a tiny flame appeared in her hand.

She looked at it with excitement, looking to Entei with the same search of approval as she had her father. Entei nodded once more, before getting up and padding away, not wanting to be left behind, the girl picked up the broken bow and chased after.

The scene changed back to the clearing, the parents hugging the child, checking for injuries, thanking Entei for safely returning her. While they fussed, she was telling them about her adventure, showing them her newfound fire ability. When they saw the flame, they looked to Entei, who was at the edge of the forest watching, with a knowing look, staring after him as he nodded and walked away.

,øººø,øººø,øººø,øººø,øººø,øººø,øºº,

The scene faded once more, the man wondering too late why Entei was in that forest when he found himself in yet another forest. When the scene finally stopped moving, he knew exactly where he was, because of a Grotle walking by.

He was on Berk, where any pokémon can live no matter the cold conditions on this island. The only place that has Truly Wilds, pokémon that are different from similar pokémon in other places. They look dangerous, are dangerous, and are not tamable. The Grotle that passed by had sharp rocks lining the edge of its shell, what should have been bushes of leaves were brambles of thorns and vines of poison ivy, the colors seemed darker than a normal Grotle, and the eyes were wild.

The sky darkened; fire could be seen.

The scene changed faster than before, now surrounded by houses and buildings ablaze, Truly Wild pokémon destroying and taking, people trying to put out the fires and trained pokémon trying to protect. The people had weapons, one of the few places to have them, and fighting along with their pokémon.

The scene was shaky, the Swellow that was tasked to watch Berk trying to avoid the flying Truly Wild's attacks. The Swellow decided to fly to the outskirts of the village, the scene steadying, a young boy being chased out of his house as a Wild Charizard burned it down using flamethrower.

The boy, scared, ran into the forest, glancing back to see the Charizard following. The boy pushed harder, searching for somewhere to hide. The scene was shaky, the Swellow trying to keep up while staying clear of the Truly Wild.

The time jumped, the boy hidden behind a tree, trying to shrink into the roots. The Charizard found him, stalking the tree, making a ring of fire around the tree, trapping the small boy. As the pokémon circled around its prey, and just like Ursaring and Entei, this pokémon was attacked by another. The boy was crying, almost unseeable in the roots, trying to get away.

It was just like the Ursaring the Charizard retreating with a snarl, sending out a quick ember towards the boy, the roots catching fire, the bot trapped. The other pokémon ran to the tree, grabbing the boy and flying high into the sky, the boy cradled to its body. The wind putting out the fire sticking to his clothes.

The man was back in the village, the Wild pokémon have gone, the fire extinguished, the Berkians already fixing and giving first aid to those that need it. The mystery pokémon came flying in, the Berkians raising their weapons, but stopped by what must have been the leader of the island. The man was tall, imposing, someone to take seriously. The man ordered everyone to back up, giving the dragon-like beast room to land.

When it landed, it gently set the boy down, being wary of the surrounding people, slowly lowering its head to the boy, checking the injuries. The pokémon growled when the leader stepped closer, trying to get to the boy. The pokémon's eyes dilated from the slits they were, slowly stepping back to allow access to the boy. The leader held him close, nodding in thanks to the pokémon.

The scene shifted as it had many times before, this time the village was at peace with the Truly Wilds, a group of young children playing with pokémon. A girl playing with a Skarmony, two kids that looked like twins having similar looking Ekans, a stout boy jumping and trying to get his helmet back from a Talonflame keeping just out of reach, and a taller, bigger boy writing something in a leather-bound book, a Carbink hovering over the book.

The girl with the Skarmony waved toward the man in greeting, and when said man turned, he saw the boy. He had a prosthetic, just below his knee, on his left leg, an Umbreon keeping the boy balanced. The children started up a game of tag, chasing each other around as the adults worked on repairs.

,øººø,øººø,øººø,øººø,øººø,øººø,øºº,

The man had many questions; what happened to the mystery pokémon; why are the villagers and Truly Wilds at peace; and what happened to the boy's leg. As the scene faded, the sun coming up, he knew these four were going to do great things. As he left, he didn't see a shadow disappearing as the sun came up.
