1 thing first:

Sorry if I failed to capture Mewtwo's personality or attacks correctly, as I'm not much of a Pokemon fan.

And thanks to 'You know who you are' for your help. :)

Just like the other Digidestined and Digimon, Davis, Veemon, Kari and Gatomon had been taken to another one of the Champion Hunter's Death Zone Stadiums where they were to face their 'great evil', however, they were confused as a part from themselves, they were the only living organisms there, however, they were proven wrong when a voice told them. "Listen to me, humans. I will defeat you so I can free Pokémon from the cruelty of every human who ever used a Pokémon for his or her own selfish purposes."

It was then Davis, Veemon, Kari and Gatomon watched as a humanoid shaped creature descended from the roof, in which the Digidestined and their Digimon partners knew exactly who the creature was, which was no doubt a Pokémon, as Ash had told them about the 'evils' he and Pikachu had faced and this one fit the description.

The Pokémon's body was a grayish-purple colour, with a purple underside and a long tail, which had a tube extended from the back of its skull to its spine.

"Mewtwo!" Gatomon called out in awe, in which Mewtwo landed gently onto the floor, before the Psychic Pokémon opened his eyes, showing they were filled with a burning with hatred, before he questioned in a calm tone. "And how do you know of me, creature?"

"First off: The name's Gatomon. You got it, you D. ?" Gatomon snapped back, before the feline Digimon stated. "And second: We know about you because Ash told us about you and your wicked ways."

"Ash?" Mewtwo questioned, before he asked. "So he remembers who I was, how?"

"That's right. He said even though you erased the memories of all the Pokémon Trainers and their Pokémon, Ash's memories of what happened on New Island slowly returned to him over time. But what I don't get is why you're working for the Champion Hunter. I thought you changed your ways." Davis stated, before Veemon asked in confusion. "And what did you mean by 'who I was'?"

"What I mean is I'm not the weak minded Mewtwo who gave up on his ambitions to liberate Pokémon from humans, but a copy of him. All I have the power of the Champion Hunter to thank for that."

"You're a clone of Mewtwo?" Davis questioned, before he asked in a joking tone. "So does that make you a Mewthree or a Mewtwotwo?"

"Neither. I'm the real Mewtwo." "The one who will right the wrongs of my world by ridding it of my foolish original body and ceasing the selfishness and darkness that lies within all the hearts of humans. Just as I will yours."

"What are you talking about?" Gatomon questioned.

"I can see you creatures serve these humans, though I don't know why." Mewtwo said, before he told Veemon and Gatomon, as he held out his right hand toward them. "However, I can save you too. Relinquish all ties you have with these humans and join me."

"Never!" Veemon and Gatomon snapped back at Mewtwo in aggressive tones, as they got ready to fight, in which the Digimon of Courage and Friendship told Davis in a surprisingly serious tone. "Davis, I've heard enough from this copy clone. Digivolve me so I can crush him!"

"Me too, Kari." Gatomon said to Kari, as the Champion level Digimon never wanted to fall off her path of Light, in which the Digidestined of Courage and Friendship and the Digidestined of Light each pulled out their D-3s, which began to glow and fill Veemon and Gatomon with energy.

"Veemon Digivolve to... ExVeemon!" ExVeemon roared out, before Gatomon announced, as she went through her stage of Digivolution. "Gatomon Digivolve to... Angewomon!"

"So you have the power to Evolve too?" Mewtwo questioned in a somewhat impressed tone, before the Genetic Pokémon asked. "What other tricks do you have?"

"You heard him ExVeemon, he asked for it." Davis replied, before he commanded. "Show him!"

"Right, Davis." ExVeemon replied, before the Champion level dragon Digimon exclaimed, as the 'X' mark on his chest began to glow, in which the Digimon of Courage and Friendship fired an 'X' shaped beam of energy directly at Mewtwo. "Vee-Laser!"

"Celestial Arrow!" Angewomon announced as she created a pink arrow of energy and fired it alongside ExVeemon's laser attack, however, it was then Mewtwo countered, in which a blue sphere encased him and absorbed the damage of both Digimon's attacks, which caused Davis and ExVeemon to groan out from frustration, as they, along with Kari and Angewomon knew that was Mewtwo's Barrier attack and would use it whenever they would try to attack him, however, the Digidestined and Digimon of Courage and Friendship and the Digidestined of Light and Digimon knew of Mewtwo reliance for his Barrier and had formed a strategic way to break through.

"Heaven's Charm!" Angewomon exclaimed, as the Angel Digimon created a cross like shape made of the same pink energy her Celestial Arrows were made of, before she fired the energy wave right at Mewtwo, but just like last time Mewtwo didn't even flinch, before the Genetic Pokémon used his Barrier attack again to protect himself from the no doubt powerful attack of Angewomon, as when her Heaven's Charm collided with Mewtwo's shielding, it created a blinding pink light, which temporally blinded the D. .

"Vee-Punch!" Mewtwo heard ExVeemon yell out, before his sight returned, in which the Psychic Pokémon was shocked to see Angewomon's attack hadn't been used to harm him, but to break his concentration so ExVeemon could strike him.

It was then ExVeemon slammed his right fist into Mewtwo's stomach, which inflicted a fair amount of pain to the Psychic Pokémon, as he was forcefully knocked back several feet back, but Davis' Digimon partner wasn't finished yet.

"Critical Crunch!" ExVeemon then exclaimed from above Mewtwo's knocked down form, as the Champion level Digimon planned to shoot down and tear the copy Pokémon to pieces with his razor sharp fangs.

But everyone, particularly ExVeemon, were shocked and confused when the dragon Digimon ceased his attack, as his fangs were inches away from Mewtwo's fallen form.

'Hey, what's going on!?' ExVeemon questioned to himself, as he couldn't move his mouth or any other part of his body, but then could see the reason why.

Mewtwo then got up, revealing his eyes were now glowing light blue, as was ExVeemon's body, in which Davis, Kari and Angewomon could see that Davis' Digimon partner was trapped by Mewtwo's Psychic attack, meaning ExVeemon's body was now under the Genetic Pokémon's complete control, in which Mewtwo demonstrated his manipulative power by slamming the Champion level Digimon into the roof, before intensifying the gravity around ExVeemon and slamming him into the ground before him.

"ExVeemon!" Davis yelled out in concern, as he wanted to help save his Digimon partner, but knew he was only human and would only get in the way.

It was then Mewtwo watched as ExVeemon weakly got up of his own free will, which impressed the D. , only slightly, that the Digimon of Courage and Friendship was resisting his power and then tried to punch him, but Mewtwo's control was far too strong, in which everyone watched in fright as ExVeemon then punched himself in the stomach, which caused the Digimon of Courage and Friendship to cough and groan out loudly, before he fell into unconsciousness.

"ExVeemon!" Davis called out in a concerned tone, before he yelled at Mewtwo in a demanding tone. "Why did you do that to him!?"

"He was trying to act on his own freewill." Mewtwo replied simply, before the Psychic Pokémon went on. "But mostly to shut him up."

Hearing that caused Davis to snap, as he was about to charge in and give Mewtwo a piece of his mind and a whole lot of payback, but Kari quickly grabbed his right arm, in which the Digidestined of Courage and Friendship looked into Kari's eyes, as he could see that the Digidestined of Light was concerned for ExVeemon too, but concerned for what would happen to Davis too, so Davis relaxed his body so Kari would let his hand go, in which the Digidestined of Light did, however, the Digidestined of Courage and Friendship grit his teeth as he felt useless that ExVeemon was in trouble and there was nothing he could do to help his Digimon partner.

Mewtwo then used his Psychic attack to force the unconscious ExVeemon to lunge at Davis and Kari, as the Genetic Pokémon prepared to strike them down with his knocked out Digimon puppet, but fortunately for the pair, Angewomon got in between and exclaimed. "Celestial Arrow!"

Angewomon then created a pink arrow of energy and fired it, which struck down ExVeemon, which caused the Ultimate level Digimon to think to herself in a solemn tone. 'Sorry, Vee, but I can't have you hurting our human partners.'

Seeing that he was unable to defeat his new human enemies without Angewomon interfering, Mewtwo then made ExVeemon's body get up, before he began to attack Angewomon with a series of punches and kicks, but thanks to her being a level higher than the Champion level dragon, the Digimon of Light was able to avoid each of the unconscious ExVeemon's attacks, however, Angewomon had forgotten that Mewtwo not only had control over ExVeemon's fighting style, but his entire being too, and was shown that when the D. threw ExVeemon right at the Ultimate level Digimon, which caught her off guard, threw her across the room and then caused her to cry out in pain as the Digimon of Light was crushed between the wall and the superior weight of ExVeemon.

Mewtwo then removed the unconscious ExVeemon, revealing Angewomon had been smashed fairly deep within the wall, before the Angel Digimon collapsed to the floor, which caused Kari to call out in concern. "Angewomon!"

But now that Angewomon was out of commission, nothing was stopping Mewtwo from disposing of the Digidestined, as ExVeemon's body approached them, or so he thought.

"Celestial Arrow!" Everyone, except for ExVeemon, heard Angewomon exclaim before Mewtwo could see another pink energy arrow being fired at him, in which the Genetic Pokémon simply held out his hand, before the attack struck it, which made Angewomon smile as she could see her attack had broken Mewtwo's concentration and had freed ExVeemon from the Psychic Pokémon's control as Mewtwo's strength was also his weakness, as he relied heavily on his mental powers and could only concentrate all of his power on one attack at a time.

"Kari, are you alright?" Angewomon asked in a curious and slightly concerned tone, as she got in front of her human partner, but then the Angel Digimon cried out in pain, as she was struck from behind by her own Celestial Arrow attack.

"Angewomon!" Kari screamed out in concern, as her Digimon partner fell to the floor, in which Davis and Kari could see Mewtwo hadn't used Barrier to protect himself, but instead used Counter to repulse Angewomon's attack right back at her.

"Now nothing can stop me." Mewtwo said in a calm tone, as his eyes began to glow light blue, before he used Psychic on ExVeemon and Angewomon to control both unconscious Digimon, in which they both got up, turned towards Davis and Kari, but before either Digidestined could react, the D. used his Psychic attack to send his knocked out puppets at the Digidestined of Courage and Friendship and the Digidestined of Light, before Mewtwo used ExVeemon to grab Davis by his throat and Angewomon to grab Kari by her throat, before both Digidestined were lifted into the air, as they could feel the grip around their throats tightening, but in their hearts they knew it wasn't the fault of their Digimon partners.

As the unconscious Digmon continued to unknowingly tighten their grips around their human partners' throats, Davis and Kari could feel themselves losing consciousness as it looked as though their time of living was up, in which they were unable to keep their eyes open and lowered their heads, before they each shed a tear which trailed down their faces and landed on their Digimon partner's arm, in which both ExVeemon and Angewomon came to their senses, quickly and gently lowered their human partners and were about to apologize and ask if they were alright, but before they did, everyone was surprised when Davis and ExVeemon were encircled in a golden aura while Kari and Angewomon were encircled in an aura of pure yellow light.

Mewtwo's eyes then returned to their original human loathing purple, in which the Genetic Pokémon questioned. 'What's going on? How come I can't control them anymore?'

"Kari, I feel funny." Angewomon told Kari, in which the Digidestined of Light replied. "Me too, Angewomon."

"Same here." Davis and ExVeemon said at the same time, before they could all feel their heartbeats racing and another sensation that surged through out their bodies.

'Hey, I remember this feeling. It's the same feeling I got when I DNA Digivolved with Stingmon.' ExVeemon thought, before he asked himself. 'But does that mean?'

'I can feel it. I can feel ExVeemon's heartbeat, beating alongside mine.' Davis thought to himself, before the Digidestined of Courage and Friendship wondered if what he thought was happening was actually possible.

'Angewomon. I can feel your heartbeat and I can feel your Light and its power.'

'Whoa, déjà vu.' Angewomon thought to herself as she remembered the first time she became Silphymon, before the Angel Digimon thought to herself. 'Only this time it feels like I'm in sync with Kari like we're becoming one.'

It was then Davis asked curiously. "You guys feeling what I'm feeling and thinking what I'm thinking?"

ExVeemon, Kari and Angewomon nodded their heads in reply to Davis' question, before they all exclaimed. "DNA Digivolution!"

"Davis Motomiya..." Davis called out strongly, before ExVeemon did the same. "ExVeemon..."

"DNA Digivolve to..." The pair called out strongly, in which their inner strength, Courage and Friendship gave them the power to Digivolve to a Digimon of unquestionable power, which called out in a mixture of Davis' voice and ExVeemon's voice. "UlforceVeedramon!"

"Kari Kamiya..." Kari called out strongly, before Angewomon called out. "Angewomon..."

"DNA Digivolve to..." The Digidestined and Digimon of Light called out strongly, in which their inner strength, Light and friendship Digivolved them from two entities to one, which, just like UlforceVeedramon, announced her name as she made her appearance, in a mixture of Kari's voice and Angewomon's voice. "Ophanimon!"

Mewtwo was left speechless for a moment that not only had his Psychic powers failed, but the Digimon had truly become one with their human partner, however, the Psychic Pokémon refused to let their fusion interfere with his plans, in which the D. placed his hands together and formed a black ball of energy, which UlforceVeedramon and Ophanimon recognized as Shadow Ball, before Mewtwo then fired the dark sphere at the Mega level Digimon.

"Tensegrity Shield!" UlforceVeedramon then exclaimed, as the Mega level Digimon created a barrier of light blue energy from his left bracelet, which stunned Mewtwo when the Shadow Ball struck it and didn't leave any signs of damage to UlforceVeedramon or his shield, before it was Ophanimon's turn.

"Sefirot Crystal!" Ophanimon exclaimed, as she launched ten energy crystals at Mewtwo, who created a blue sphere and encased himself in a protective Barrier attack, however, all ten of the Angel Digimon's crystals broke through his Barrier and struck him down.

But it was as Mewtwo got to his feet, that he groaned out as UlforceVeedramon grabbed him by the throat, before the Psychic Pokémon was in for a world of hurt.

"This is for using me as your plaything!" UlforceVeedramon roared out, before he slammed his right fist into the left side of Mewtwo's head.

"This is for and this is for making me harm the ones I love!" UlforceVeedramon then roared out, before he slammed his fist into Mewtwo's face again.

"And this is for being a no good, self-centered jerk!" UlforceVeedramon roared out loudly, before he slammed his fist twice as hard into Mewtwo's face, which knocked the Genetic Pokémon back several feet.

It was then Mewtwo weakly got to his feet and could see the determination, trust, respect and love that the Digidestined and Digimon held for each other in their eyes, in which the D. closed his eyes and lowered his head in defeat, as he thought to himself. 'It seems I was wrong. Thank you for opening my eyes, Digidestined. Now, I'm ready.'

"Ulforce Saber!" UlforceVeedramon exclaimed, as a light blue coloured blade extended from his right V-Bracelet, before the Mega level Digimon shot at Mewtwo, and without defending, stabbed his blade through the Genetic Pokémon's chest.

UlforceVeedramon then removed his blade from Mewtwo's chest, in which the Genetic Pokémon slowly collapsed onto his stomach, smiling as he did so, as he had seen the error of his ways and could die happy.

It was then UlforceVeedramon and Ophanimon watched as Mewtwo's body began to dissolve into a pile of white sludge, as his genetic makeup was beginning to grow unstable and with his death, the Psychic Pokémon was no longer able to maintain his form, in which UlforceVeedramon and Ophanimon were seen as the victors and were taken out of the stadium by dark red energy.
