It was a dead end for the man. Run as he may, the crook and his Houndoom were faster, and now he was trapped. The thief pinned the man against the chain link fence, swearing like a sailor and snarling like his Pokémon. "Don't hurt me man! Here, here's my wallet! Just let me go…I've got kids fella, I've gotta get back to them, just please take the money…"
"Keys too," the thief hissed.
"Please, don't do this to me…" the man whimpered, but when that Houndoom snarled- and oh, did it sounded like a nightmare- he handed them over helplessly.
Turning around, though, both the Houndoom and his trainer saw their way was blocked off by an eerie figure in what looked like a tattered brown robe. Unable to see the person's face or hands, the man considered that this guy (or girl?) looked kind of like the grim reaper.
"Outta the way!" shouted the thief, echoed by his Houndoom's barking. The figure remained silent, however. It raised its arms and both trainer and Pokémon were drawn up into the air like marionettes, surrounded by a weird blue light. In a single thrust, the thief was knocked unconscious against the wall, and while the Houndoom at first exploded in enraged barking and growling, it gave way to anxious whining as the figure drew near. Not one to take chances, it seemed, the figure flung the Houndoom to the alley's entrance and permitted it to run away. So much for honor among thieves.
The pulled out the man's money and keys and levitated them into grabbing distance. Half-mortified, half-fascinated, the man stuttered out a thank you and ran away.
The figure did not, however. Wasting no time for the police to arrive, it kneeled over the thief, and stripped him of what cash he had, besides knick-knacks like…well, like this star piece, for instance.
Satisfied with its "wages" for the night (well, by now it was technically morning), Mewtwo returned to its base of operations- a rundown, abandoned apartment building. The building was home to many Pokémon these days, mostly Rattatas and Meowths, with a Spinarak or Gastly here and there, besides the groups of Pidgey and Starly that nested on the roof; all of the Pokémon in the building, however, generally left Mewtwo alone.
Now was about the hour that Mewtwo would stand on a corner of the apartment building, pondering its fate, asking of itself those questions that most rattled its mind. For example- was it right to steal from thieves? In a world where there's no free lunch and some Pokémon ate other Pokémon, perhaps this was the only way those desperate souls could eke out a living. On the other hand, why, then, did they pick targets that looked like they couldn't defend themselves? From Mewtwo's experience, it did not at all even phase these criminals to strip others who barely had anything themselves. Amongst Pokémon, even predators seemed to have some respect for their prey- yet that was not all the case amongst these criminals…
And it went on as such. Ultimately, Mewtwo could only feel so much guilt. It considered what it did as a service to the city. Anything of any real value Mewtwo placed on the windowsills of poor families because, as a Pokémon, it had no real use for money. Once, early in its career as a vigilante and a traveler, Mewtwo would keep only TM's and HM's, using those that it could and exchanging the rest with move tutors (after whose teachings Mewtwo would wipe their memory of having met it). These days, however, Mewtwo had no use of most anything, except for food, water, and sleep- which all seemed to be at a premium.
Floating through the broken window of its room below, Mewtwo took one last look at a newspaper article about the city's "mysterious, silent hero" before curling up and drifting off to sleep.
Nothing good can last, they say, and in the case of Mewtwo's sleep, that was true. The Starly flock above got up rather early to make their racket. Earlier than usual in fact, Mewtwo noticed. Shrugging off the impertinent birds, Mewtwo was about to go into the hall when one of them called to him from the broken window.
"Hey, ummm, you!"
"What?"
"There's this one Pokémon here that wants to talk to ya!"
"Send them in, then." Mewtwo didn't even bother turning around. It was probably just some plucky Spearow or something that wanted to try its luck against him. That sort of thing happened from time to time, but most of Mewtwo's challengers chickened out when they saw it, and those that didn't were soundly beaten. Not the sort of thing Mewtwo savored, though, as it much preferred to fight stronger Pokémon.
Mewtwo heard something chirp "hi there!" from right behind it…Wait a moment, that voice…Oh no. That high-pitched mewling…Mewtwo winced.
"Hello…Mew."
"Long time no see, eh? So, still haven't got your own voice, Mewtwo?" Mew zipped and zoomed around the room, touching everything and generally being a disturber of the peace.
Suddenly feeling rather self-conscious, Mewtwo cleared its throat. "I can speak, you know, I just choose to save my voice…"
"Well, well, don't bother 'saving' it for me. I'm company, and you're my host and stuff."
Mewtwo wondered if company was synonymous for parasite in that sentence. "You know, technically, and to my great chagrin, you are a relative of mine."
"Oh, save it. You never call, you never write. It's been how many years now?" Mew huffed, "Some relative you are, yes indeed!"
Mewtwo smacked its forehead and made a mental list of the places it would like to teleport Mew to. "You're not here to catch up with me, Mew. You wouldn't have bothered," now it was Mewtwo's turn to sound offended, "You're here for a favor of some kind, no doubt, so can we just get this over with."
Mew sighed, as though its good mood had been genuinely deflated. "Fine, have your way. Yes, I'm here to ask something of you, but the request is simple and painless, really. Have you heard of the Hall of Origin?"
"No…where is it, and what's there?"
"Suffice to say it's a kind of meeting ground for legendary Pokémon, and the home dimension of Arceus, who has asked to meet you. The Hall of Origin could be accessed from anywhere, I guess, but it's…customary, I guess, for those who are able to go through at Spear Pillar at Mt. Coronet."
"What an unusual custom…" Mewtwo eyed Mew wearily.
"But it is! Honest! C'mon Mewtwo, it'll look bad if you don't come!" Mew certainly was getting rather anxious…
Come to think of it, though, so was Mewtwo. Very subtly something in the air had changed, and looking at Mew, Mewtwo could tell that both felt that something was just off somehow, just wrong. The sort of feeling you get just before seeing an oncoming tidal wave. "We should get out of here," Mewtwo concluded, unable to bring the words out of his throat, not wanting to ruin the silence…And what silence it was. What happened to the chatter of birds, and of humans? Where was the roaring of cars driving past?
In spite of their instincts to remain hidden from Man's gaze, the brooding silence compelled them to investigate its source. Mewtwo and Mew floated outside of the apartment building and onto its roof. Above them, right before their eyes, a mass exodus was occurring. Everything with wings, everything that could float or fly, was flying frantically to west. The very Sun was dimmed for the multitude of wings.
Below them, the less fortunate Pokémon and humans were dropping what they had, abandoning buildings and cars. Looking towards the source of their fear was a sight that would've made lesser souls faint entirely or deny the reality of it. Looking down Main Street in the distance, Mewtwo saw a great ruby titan of a Pokémon roar, and as it did, the earth trembled, pavement cracked, and the city's denizens tumbled to the ground. Behind the red behemoth marched a large army of what looked to consist mainly of ground-type Pokémon. The army filled the streets, and some of the bigger Pokémon soldiers overturned every vehicle in their path.
"Now'd be a good time to book it, methinks," Mew remarked, and after looking at Mewtwo's shock and outrage, added, "Now's not the time to get territorial Mewtwo. The both of us together couldn't take on all of them."
"Perhaps not," Mewtwo shot back, "But the people and Pokémon of this city deserve at least a fighting chance to escape…I believe we can provide them that." Without further ado, Mewtwo rushed to the frontlines, and with an exasperated sigh, Mew followed.
Some of the city's residents, it seemed, had formed their own resistance, standing defiantly in front of the oncoming army- albeit, keeping a distance of about a hundred feet from it. Their mouthpiece was a brazen young trainer with a megaphone.
"What's the big idea here? What do you think you're doing, huh!"
From across the way, a human with his own megaphone stood across the way. "This is Groudon, my master, who has come to call out all of his ground and rock-type brethren to join the fight against the great forces that are coming to destroy you. Other Pokémon and humans may also join the fight, but they must swear fealty to Groudon."
"And what if we don't wanna join? What're ya gonna do then?"
"What Groudon asks is not a request- it is a demand. All land, including this city, is Groudon's. Join peacefully or you will be crushed." Some Pokémon and some people looked amongst themselves, seeing who would go. Sure enough, out of the city's crowd came some who looked fearful, and some who looked brave, but about a quarter of the crowd in all left and stood on Groudon's side. The remainder stood still, mortified, but ready to fight.
Mewtwo looked at Mew, who nodded solemnly back. The two swooped to about three hundred feet of altitude and between Groudon and the crowd. With all of their might, the psychic cats erected a circular barrier about two football field lengths in diameter. Not impassible, perhaps- especially for Pokémon that could tunnel- but it would certainly be annoying and it would buy the crowd some time. Indeed, the crowd, though brave, got the message. Most were too panicked to even look for the barrier's source.
The army was not so skittish, however. Groudon looked at Mew, then at Mewtwo, and bellowed in rage, which sent its army rushing at the barrier, pounding away at it. Groudon itself joined the effort, and every blow was smarting to both Mew and its superclone comrade. Mew turned around and started kicking at the air, as if that would somehow help to keep the barrier propped up.
"Can you see if they're gone?" Mewtwo asked, grimacing.
"Just a little longer…" came the telekinetic whisper.
"It won't hold much longer!"
"This was YOUR idea! And anyway, I think they're in the clear now. Ready to let go?" Mew turned around and saw Mewtwo nod. "One, two…" the barrier vanished.
The distraction wasn't as much of a help as they thought it would be, though, because Groudon still held his gaze forward, looking on at his quarry. That wouldn't do. Mewtwo hurled a Shadow Ball right at Groudon's nose and uttered the loudest, most pantherine scream it could muster while Mew tried pulling down the foundations of weaker buildings to further frustrate the army's efforts. More incensed than injured, though, Groudon shouted back and brigades of Flygons took to the air and were headed right for Mew and Mewtwo.
"Now would be a good time to leave, I think," Mewtwo offered.
"You read my mind!" Mew giggled, despite the situation, "Can you teleport the base of Mt. Coronet? I can lead you up to Spear Pillar from there." Mewtwo nodded, and just as the Flygons came within feet of them, they disappeared.
