(A/N: Yes, I know, the chapter title is a bit of a pun on Dragon Ball Z, but what can I say, it works. I should have mentioned something last chapter. If you weren't satisfied with the description I gave of Mega Mewtwo Z, you can see an image of him on Google. Just do a search of "Mewtwo Z", and you'll find plenty of fan-art for him. Then just imagine him as green instead of purple for his shiny form. He actually looks pretty intimidating, even more so than Mewtwo's base form.)

Chapter 14: Mega Evolution Z

Mewtwo would never admit it, but he felt a shiver of fear run down his spine. He barely had time to think before Mirage Mewtwo teleported in front of him and used Mega Punch crossed with Faint Attack. Mewtwo went flying, but didn't get far before vines grew out of Mirage Mewtwo's palms, shooting out to use Vine Whip with such intensity that that Mewtwo slammed into the ground hard enough to crack it.

The vines then wrapped around him, either using Bind, Wrap, or Constrict, Mewtwo wasn't sure; possibly all three. He was lifted into the air and slammed down repeatedly until he used Psystrike, the psychic explosion disintegrating the vines. Mirage Mewtwo immediately teleported over to him and breathed a cloud of Poison Powder and Stun Spore.

Mewtwo teleported out of the cloud before either of the powders could take effect. If Mirage Mewtwo was going to try and poison him, then he would do the same. He used Toxic, spitting out a wad of dark purple, nearly black, fluid. Mirage Mewtwo didn't bother trying to avoid it, yet as the fluid seeped into its body, there was no sign of poisoning.

Mirage Mewtwo teleported in front of Mewtwo. It's hands shot out as it used X-Scissor, but Mewtwo managed to put his shield up in time. Mirage Mewtwo quickly retaliated by using Dark Pulse, the Dark attack passing straight through Mewtwo's shield.

As Mewtwo fell back, Mirage Mewtwo grabbed him, and they sped to the ground as the Mirage Pokémon used Seismic Toss. It let go at the last second and pulled out of the dive, intending to have Mewtwo slam into the ground, but Mewtwo was able to use his psychic power to stop his momentum. He then used Will-O-Wisp, throwing blue fireballs up at the Mirage Pokémon.

Mirage Mewtwo's psychic shield appeared around it. As the fireballs blasted against it, Mewtwo saw that the Mirage Pokémon's psychic color had changed from blue to purple. He didn't have time to dwell on it though as Mirage Mewtwo sped towards him.

Trying another tactic, he used Hypnosis, but the hypnotic waves had no effect, and Mewtwo received a Mega Punch to the face for his troubles, sending him crashing into a tree and reverting back to his base form.

Chuckling, Dr. Yung shook his head. "I would have thought you would have figured it out by now. Since Mirage Pokémon are artificial. Certain attacks can't affect them. They can't be rendered paralyzed, poisoned, confused, burned, frozen, or put to sleep. It's just one more way my Mirage Pokémon are superior to real Pokémon."

Mewtwo forced himself to his feet and Mega Evolved to his Y form once again. While his X form held many advantages, against Mirage Mewtwo, his Y form would be his best chance.

A knowing smile crept up the doctor's face. "It doesn't matter what form you take. My Mirage Mewtwo's Z form will not only match it, but surpasses it in the areas that your form does not specialize in." Then he nonchalantly shrugged. "But by all means, fight to your heart's content," his smile widened, "while it still beats."

He snapped his fingers and Mirage Mewtwo held up its hands. Several Shadow Balls appeared and began circling around it. One by one, they flew at the genetic Pokémon. With his great speed, Mewtwo maneuvered around the attacks as he sped towards his doppelganger. Upon meeting it, he threw an Ice Punch, but to his shock, Mirage Mewtwo caught his fist. And while the power of the attack still took effect, covering Mirage Mewtwo's hand in ice, the coating shattered as the Mirage Pokémon squeezed Mewtwo's hand to the point of crushing his bones. He attempted to pull his hand back, but was unable to until Mirage Mewtwo willingly released him.

The tentacle hanging from Mirage Mewtwo's head wrapped around Mewtwo's neck, cutting off his air supply as it lifted him off the ground. The end of its tail then shaped itself into a fist and slammed into Mewtwo's gut with a Fire Punch. At the same time, its own actual fists also struck with a Shadow Punch and a Thunder Punch just above where its tail struck.

Spittle flew from Mewtwo's mouth from the three simultaneous blows. Already unable to breathe from the tight grip around his neck, any air he still had left in his lungs was forced from his body. One eye cracked open to look at the blank stare of the Mirage Pokémon, and he was filled with renewed determination. He would not be defeated by a mere hologram.

Summoning up his psychic shield, he forced Mirage Mewtwo to release him. He then slammed into his opponent, pushing it back until they slammed into a tree, snapping it in half, and kept going. Several more trees received the same treatment until Mirage Mewtwo's hand shaped itself into the head of a Houndoom, and it used the Dark attack, Crunch, to reach through Mewtwo's shield.

His speed saved him as he flew back away from the snapping jaws, but he could not avoid the Dark Pulse that followed, going straight through his shield, causing him to slam into a tree. As much as he loved nature, he was getting tired of all these trees.

Gritting his teeth, he forced himself to his knees and fired a Psychic. Mirage Mewtwo simply teleported out of the attack's path, appearing in the air above him. A dark aura appeared around the Mirage Pokémon and Mewtwo was suddenly hit by a Shadow Wave, knocking him back down. This was followed by several more Shadow attacks, including Shadow Fire, Shadow Bolt, and Shadow Chill.

A crater had formed around Mewtwo, growing larger with each impact from Mirage Mewtwo's attacks. With a wave of its hand, the Mirage Pokémon used Fissure. Mewtwo detected the attack, along with the devastating damage he knew it would cause him, and he quickly used his psychic power to stop it.

Mirage Mewtwo tried another Shadow move, using Shadow Rave to cause spikes to shoot up from out of the ground to impale Mewtwo, but the genetic Pokémon teleported and reappeared a distance away. Mirage Mewtwo turned to look at him, its blank eyes not really seeing.

Mewtwo's own eyes narrowed. "All that power, and yet you can't even think for yourself."

This was meant to be an insult, yet Dr. Yung just laughed on Mirage Mewtwo's behalf. "That's the beauty of it. There's no free will, thus no cause for disobedience. No doubt, no fear, no hesitation, compassion, pity, sympathy, or any other foolish emotion or thoughts that may hinder my Mirage Pokémon from carrying out my orders, whatever they may be."

Mewtwo glared at him. "That is not life. It is merely the imitation of life. It's a flasehood."

"It's control," Dr. Yung insisted. "Absolute control. And whoever has control over something has absolute power over it. With Mirage Mewtwo, I will control this whole world. Eventually I will move beyond this realm and take over the dimensions of the Unown, even Palkia, Dialga, Giratina, and eventually Arceus himself. With Mirage Mewtwo by my side, not even they can stop me."

"No," Mewtwo reluctantly agreed. "But I can."

The doctor's smile widened. "All evidence to the contrary. Mirage Mewtwo, show him what you can do."

Mewtwo was ready for whatever attack, or series of attacks, the Mirage Pokémon was about to perform. What he didn't expect was to see Mirage Mewtwo unleash numerous attacks all at once in different directions. Moves of all 19 Pokémon types erupted in a mass explosion as dozens upon dozens of attacks were fired all at once. Mewtwo put up his shield to defend against a majority of them, but the Dark types still flowed through and over him.

He skidded backwards, his feet digging into the ground until his shield dropped from the assault. Mirage Mewtwo was suddenly there, right in front of him. It raised its hand and unleashed a Fire Blast. Mewtwo caught the attack, but Mirage Mewtwo immediately followed up with a Thunder, followed by Water Pulse, Psybeam, Ice Beam, Seed Bomb, Dragon Pulse, and Signal Beam. It then teleported behind Mewtwo and used with Hyper Beam, Mirror Shot, Shadow Wave, Rock Blast, Night Shade, Air Cutter, and Dazzling Beam.

The process repeated with Mirage Mewtwo teleporting to one spot, unleashing a various series of different attacks before teleporting to a different angle and using several more. Mewtwo managed to hold the attacks back, the power building up around him, but when Mirage Mewtwo finally used the Dark attack, Night Daze, he was unable to block the move. The impact of the attack caused him to lose his hold on the other attacks, and they all slammed into him at once.

Caught up in the blast, he barely had time to process what happened before Mirage Mewtwo struck him with an Iron Tail attack, sending Mewtwo flying into a tree with such force that he knocked it over. Dropping to the ground, he reverted back to his base form, feeling his strength leaving him rapidly. Mirage Mewtwo stood a distance away, looking as fresh and ready for battle as it had since the moment it had materialized.

A smirk grazed Dr. Yung's face and he began typing again. "Well, I believe that about wraps it up. A noble attempt, my friend, but pointless nonetheless."

Pointless? Was this human calling all that he had done pointless? Never, he would never allow a mere hologram to defeat him. He would defeat this Mirage Pokémon if it was the last thing he did. If not for his sake, then for the sake of the world.

For the sake of her.

Struggling to get to his feet, Mewtwo's legs managed to support him as he summoned up his reserves to send a powerful Psychic attack at Mirage Mewtwo. The Mirage Pokémon didn't even try to dodge or block it. And when the attack hit, nothing happened. The attack didn't even affect Mirage Mewtwo at all.

"What?" Mewtwo gasped.

"Oh," Dr. Yung replied, "I restored all of Mirage Mewtwo's resistances and immunities. Your Psychic attacks won't work on his Dark type's resistance."

Mewtwo's eyes narrowed. "Very well, then I will use non-Psychic attacks."

He unleashed Thunderbolt, but just like his previous attack, Mirage Mewtwo remained unaffected.

"You don't listen very well. I told you that my Mirage Mewtwo has the resistances and immunities of all Pokémon. Rock type Pokémon are immune to Electric attacks. At most, you'll only be able to use attacks that are not very effective. " He chuckled at the glare Mewtwo fixed him with. "Don't look at me like that. The battle is already won. It's obvious that you're no match for my Mirage Mewtwo. The test is over. I'm satisfied with my results."

Mewtwo's fists clenched. "It is not over."

"But it is. It was over before it began. I even had to make Mirage Mewtwo vulnerable to your attacks to actually give you a chance in the first place. Even your physical attacks would have been useless if I hadn't turned of Mirage Mewtwo's Ghost type immunities to them. And, might I add, since my Mirage Mewtwo knows every attack there is, I could have easily had it use Imprison to prevent you from using any attacks the two of you share, making it so you couldn't even attack it at all." His grin widened. "Face it, Mewtwo, you're finished."

Anger flashed in Mewtwo's eyes. "No, you are finished!"

He threw a Shadow Ball at the doctor, but Mirage Mewtwo did the same, knocking Mewtwo's attack off course. It then used Telekinesis on Mewtwo, and he suddenly found himself unable to move.

"Time to put an end to this," Dr. Yung told his Mirage Pokémon. "Mirage Mewtwo, finish our friend off with an Ultimate Hyper Beam!"

Mirage Mewtwo raised its hand and began gathering energy. Fear gripped Mewtwo. That Ultimate Hyper Beam attack had been devastating before Mirage Mewtwo had been upgraded. How powerful would it be now that Mirage Mewtwo was in its new much more powerful Z form. The destruction would be catastrophic. And here he was, trapped by Mirage Mewtwo's Telekinesis, unable to even teleport out of the attack's path.

Dr. Yung continued to smile proudly as his Mirage Mewtwo's continued to gather energy. "It's almost over."

"YOU LEAVE MY MATE ALONE!"

He turned to the cry of, "MEW, MEW, MEW, MEEEEW!" and saw Mew flying towards him. She thrust out her hand, her finger extended. All around her arm, a cone of energy spun around as if it were a drill.

"Horn Drill!" she bellowed, stabbing forward with her attack.

Dr. Yung reacted instinctively, shutting his eyes and holding up his hands to defend his face. This included raising the laptop he was holding, and Mew's attack pierced the back of it. The impact pushed Dr. Yung back until he slammed into a tree.

Cracking open an eye, he stared into the furious face of Mew as she glared at him. Sparks flew all around her as they sprayed from the back of his computer where her attack touched. He had a sudden flashback to his old Mirage Mew. Somehow, that flawed creation of his had developed actual sentience and free will, and had managed to sabotage his plans back then. Now this Mew had come out of nowhere and was trying to interfere.

"I hate Mews!" he shouted.

Mew's gaze hardened. "That's fine, cause I don't like you much either!"

With a loud cry, she pushed harder. Her Horn Drill pierced the back of the laptop, bursting through the screen. Dr. Yung's eyes widened in horror at the ERROR message that began flashing across the cracked screen. "No! What have you done?"

The energy Mirage Mewtwo had been gathering dispersed as the Mirage Pokémon grabbed its head and began wailing as if it were in pain. Its body became staticky as its pixels distorted and reformed in rapid succession.

Mewtwo could suddenly move again. He wasted no time. Mega evolving to his Y form once more, he cupped his hands together, putting all his power into creating a Shadow Ball that he threw at Mirage Mewtwo. The Mirage Pokémon didn't even seem to notice the attack as it exploded against it.

When the smoke cleared, Mirage Mewtwo seemed to be falling back in slow motion with a big hole in its chest. Dr. Yung stared at the Mirage Pokémon, shaking his head in disbelief. "No, it can't be…"

Mirage Mewtwo's body began breaking down into data particles, starting at the hole in its stomach and spreading outward until the Mirage Pokémon disappeared. The dome-shaped data field began pixelating as well until it disappeared along with Mirage Mewtwo.

Collapsing in exhaustion, Mewtwo returned to his base form. Concerned, Mew flew over to him. "Mewtwo, are you ok?"

He held a hand up to silence her. Taking a few deep breaths, he used Recover. Feeling much better, he rose to his feet. "I am fine. Thank you."

Mew sighed. "That's good. What happened?"

"It is a long story. I will tell you later; don't read my mind," he added, knowing her too well.

She had just been about to do that, but stopped at his request. "Oh, ok."

He glanced at her, feeling a mixture of emotions he didn't know how to describe. "Why did you come back?"

She cocked her head to the side. "Isn't it obvious?" She flew over to him and hugged his arm. "Because I'm your mate."

A short distance away, Dr. Yung was fiddling around with his busted computer. "It's ok. The computer's a regrettable loss, but it doesn't matter. The data is what's important. If I can just get the memory card."

He pried at the slot on the side, and the small square object popped out. The computer was ruined, but the memory card containing everything for his Mirage Pokémon System and all the Pokémon information was still intact. As long as he had this data, he could always build a new machine.

"Success," he exclaimed, holding up the memory card.

It immediately started glowing blue and floated out of his hand. A startled look crossed his face and he reached for it, only to have the blue aura surround him as well and slam him against a tree, his feet not even touching the ground.

Mewtwo's eyes were glowing as he brought the memory card over to him. "So this is the source of all your evil."

"Put it down!" Dr. Yung shouted desperately. "All my life's work is on that! It has everything!"

Mewtwo just glared at him, and the memory card exploded into a shower of metal splinters.

"No!" Dr. Yung bellowed. "What have you done? It's gone! All gone! You've ruined everything! I'll have to completely start from scratch!"

Mewtwo was suddenly in front of him. His hand shot out, grasping Dr. Yung's face. "You will start nothing over. Your wicked deeds end here." His eyes narrowed. "It would serve you right if I erased all your memories since birth and left you as a blank slate with no idea of who you are. But I am not that cruel. Besides, I have a much more suitable punishment."

He leaned in close. "Instead, you will forget everything about your work. All your plans, the information you've gathered, the knowledge you've learned, even what you were working on will be forgotten. You will forget it all. However, I will leave you with the knowledge that you had something you had spent your whole life working on, something you had succeeded at and could have used to take over the world with it, only to lose it. You'll be cursed with the fact that you will never be able to replicate it, that it is lost to you forever."

Dr. Yung's eyes were wide with desperation. "Please… Please, don't…"

But there was no mercy in Mewtwo's gaze. In an instant, the doctor's memory was wiped of everything relating to his Mirage Pokémon System, Mew, and Mewtwo.

(A/N: And after an epic battle and a surprise rescue from Mew, Mirage Mewtwo and Dr. Yung have been defeated. And it doesn't look like he'll be creating anymore Mirage Pokémon. I was kind of upset that we never got any closer on what happened with him, but, oh well. In other news, Mew came back. What is going to become of her and Mewtwo. Now that Mewtwo has felt what it was like to lose her, maybe he'll open up his heart. The next chapter will be the last one, the epilogue in fact, so it'll be shorter than normal. I'll be posting it Friday, so stay tuned for the conclusion. I know it may seem sudden, but there's a reason I'm ending it there, which you'll understand next chapter.)
