It all happened so fast to Mew, in her whole life, almost a full millennia in fact, she had never experienced this debacle. A small war between originals and clones of Pokémon. It was strange, to say the least, she had seen spats between Zangoose and Seviper, even between fire, grass, dragon, and bug types with their respective kin before, but not to this extent. The other being, Mewtwo, as he called himself, was responsible for that. She couldn't do much, he was (arguably) stronger than her, but she had way more experience than he could ever hope to be (it actually made her wonder just how old the clone was). She was actually surprised Lugia, Groudon, and, even Rayquaza, didn't come to the source of the storm yet. Maybe none of them had quite noticed the weather phenomenon. (It didn't make sense to her, but hey, at least they stayed out of Kanto this time.)

That's when it happened, they launched blasts made up of excessive psychic energy. Mewtwo, with a psychic move she didn't know the name of, and her with a duplicated variation of it (courtesy of Copycat). Someone intervened, a young boy with an insanely massive aura, that also attempted to punch Mewtwo (lol, she absolutely loved that bravery). He ran right into the blasts just before they collided. The two energies appeared to of killed him to most, but she saw his aura and the psychic energy scattered in the air, leaving his body in a petrified state of sorts.

She had to make a list, because the next thing to occur unexpectedly to her, the tears of the Pokémon (originals and clones alike) begun to gather around the boy. The tears began to bring the Aura and Psychic energy back into his body. It surprisingly worked, the life restored to his body.

It seemed like it was okay... at first. Then the situation became rather dreadful. Mew's sensitivity to energy went off, as both her and, probably Mewtwo (though he was no longer watching, more lost in his mind), saw it. The boy, Ash's (if she recalled what the other humans had said) aura became more aggressive, trying to repel the psychic energy that was now contained within his body. This had the chain reaction in their psychic power to reacting identically.

Mew, now realizing the detrimental effects of this, was very concerned for the human. Normally, when someone's energy reacts to an outside presence, it's will attempt to overtake the other for a bit (maybe two minutes? Three minutes...? ten, maybe...?), both likely fighting until one overtakes the other.

However, much to her astonishment, the aura within the boy was just as strong and large as their combined energy, he likely would've lived for a long time with how much was in him. But the two powers were just too big to overtake the other, his body will (probably) rip itself apart before it could stabilize... or he could blow up (it remonded her of a Golbat that drank too much blood, it was quite the traumatic memory).

She pondered what to do for a moment... 'Maybe, it's time I...' as she descended downward towards him quickly.

Mewtwo stared off, deep in thought, '... I was incorrect. I believed that this world was determined by how one was born... Now, however... I now know that it matters what one does in life.'

Mew hovered above Ash's body, careful not to come closer (unless she wanted to get hit by the unstable energy that sparked with violence). Disregarding the Mouse Pokémon, she begun to generating a wave of deep, pink, psychic energy, enveloping them both (and Pikachu).

Ash blinked, seeing a void around him, "Uh, hello?"

"Hi!"

Ash stared at the Mew in astonishment, "Uh, did you just talk?"

Mew released a fit of giggles, "Of course I can talk, we're in your head."

"Why is it empty?"

"Do you really want to know?"

After a moment, Ash glanced away, "No, I don't think I want to."

"Good."

"So..." He paused slightly in confusion, "What happened? I felt an electrified scensation for a moment."

"Oh? You're dying."

"WHAT!?"

Mew flailed her arms in a childish manner, "I AM working on it!" Before she gained a michievous look.

Ash did NOT like that look. "What?"

"I've got a way to save you, do you want take it?"

Ash asked, "Well, of course. I want to become a Pokémon Master!" He froze, realizing that he was talking to a feline with an eldritch power, "Is there anything bad that'll happen?"

Mew tilted her head, her michief growing more, "Well~... Let's just say... You're going to feel... Transformed..."

"What?"

"Warning's been given, here we go." As she let loose a wave of excessive pink energy in all directions of Ash's mind.

The light shifted to a softer tint of pink, the dome rippling heavily with energy, the energy tightening heavily. The light erupted blindingly in all directions (resembling a Dazzling Gleam). Everyone, including Mewtwo (who had finally noticed what was going on), stared in astonishment at the beauty of the energy.

The glow gleamed, before it begun to shrink, fading away. When it faded, it left a singular Mew with Pikachu. Unlike other Mew from before, this Mew had blue fur, a sparkles of light emanating around it.

Pikachu stared in confusion, a weird comprehension filling his heart, as the Mew begun to stir. "A-Ash...?"

The off-colored Mew replied groggily, "Yeah...?" Turning his head to voice, he deliriously asked, "Who said...? Pikachu, did you say something...?"

Before he could react, the new Mew was scooped up in a crushing hug, as Pikachu scolded with jubilee, "If you ever see two energies, never do that again! I thought you were dead!"

Ash choked, "Pikachu... I don't think... I'll live long enough... to try that again..." As Pikachu released him, patting on his back lightly while he collected air.

As the delirium fade, he looked down at his hands (or paws???), he asked, "What happened to me...?"

Pikachu patted his back lightly, "Well, it looks like you turned into a-"

"ASH! ARE IN THERE!?" As he was Skull Bashed by Squirtle, the turtle swinging him around like a girl overjoyed about her doll. "STAY CALM! WE WILL GET YOU OUT!"

Bulbasaur whacked the Squirtle upside the head, causing him to drop the cat. Bulbasaur scolded, his head practically becoming big headed over Squirtle, "Are you trying to harm the idiot we call a trainer?"

Misty asked from a distance, the situation sinking in, "Brock... please tell me what I'm seeing is wrong..."

Brock asked, "No... considering how Squirtle and Pikachu acted, I think we just saw what happened to Ash.. "

Joy questioned, "But where'd the other Mew go? How is this even possible?"

"Forgive me, but I will be taking things from here..." As the other Humans and their respective Pokémon were levitated. "You will forget the events of today." As they were warped away. Turning to the former Mew, he came to the realization that they needed to have a discussion about this.

AN: This is an official rewrite of the original 'Mew's Legacy' by neoblackheart1. The original creator wasn't able to proceed further with their story due to not knowing how to continue the story the way they did it originally.

Please tell me how I did, or if there's any Pokémon or changes you want me to changes about the original story.
