In order to gain a better understanding of this story, please read the first part of Mewtwo's experiment, I hope it will make more sense.
This story takes place years after Pokemon: Black & White, where Ash and some of his friends visit North America, and find a house to live in before returning home.
In this story, Mewtwo attempts to subdue the clone of the human he was trying to emulate, but in this chapter, you can see that he is having difficulty performing that task.
Sorry about the confusion in the previous chapters (I type almost quicker than I can think with my brain).
A skirmish between two strong creatures, one with extreme power, one with a loyal friend and fanatical attachments to his morals. They both exchanged blows,
and displayed their quasi-religons fiercly. It was an odd concept, a Pokemon being the father of a human adolecent, except this human was a clone, and he had
only existed for a few days after hatching. Why were they fighting? One did it to protect his son, his son fought to stay true to his morals. They both clashed,
and it quickly became noticable.
One was called Mewtwo, a fierce warrior Pokemon that was created from Mew. The other was a human clone called Deviant, a spiritual being who was strongly
tied to the concept of right and wrong, and constantly craved justice and tried to enforce it anywhere and anytime he could. One was a wanderer, and the other
was a formalist, but both had massive internal strength, and had an intense passion for skirmishes.
"Quick being such an idiot and come home with me!" Mewtwo yelled as a deadly stream of psychic energy missed him by an inch.
"Poor, petty Mewtwo, immobilized by his desire to study," Deviant mocked insultingly. "I am not your 'tool', I am a living creature who is actually fighting for you and the rest of the good sentient beings of the universe. But if you don't change your behavior, I'm going to destroy Team Magma and Team Rocket, and I'll come back and dominate you and the other clones."
Deviant jumped up and cleared the path for Yogirasu's incoming hyper-beam, which blasted Mewtwo across the street. Deviant leaped into the air, and collected the black mist he created, and formed a transparent sphere of dark-blue light into his hands.
"Mewtwo, did you really study human culture?" he asked while focusing his power. Mewtwo ignored the question, and sent out a stream of blue psychic pulse beams.
"You're trying to stun me?" Deviant questioned as he dodged each of them with a quick, and thoughtless pace. "You have more fight in you than I thought," Mewtwo said with a grin.
Mewtwo stood up weakly, and tried to walk in the middle of the street. Mewtwo jumped in excitement when he caught a glimpse of Ash bolting out of his house. "Mewtwo! Are you okay?" he shouted as he ran in Mewtwo's direction. "Ash, go back inside right now!" Mewtwo ordered loudly.
Yogirasu grabbed Mewtwo by the legs, and held him down on the ground so that Deviant could finish him off.
"Alrighty almighty god of all Pokemon," Deviant said to Mewtwo atrociously. "Let's just end this right now and go back to being peaceful civilized beings, okay?"
Mewtwo groaned and fell limp, barely maintaining the strength to breathe. "Alright Yogirasu, I think he's had enough," Deviant instructed his Tyranitar.
Yogirasu released Mewtwo, and let the cloned psychic Pokemon rest on the ground.
"You know Deviant, I think you're motivation for battling doesn't come from your honor, ethics, or desire to bring good for all innocent people and creatures across the universe," Mewtwo explained. "I think you're just doing it due to your feelings for that whore of a gym leader, and you're just trying to show off to get her to be your bride."
Deviant's eyes lit up with a furious dark-blue hue of rage, while gigantic waves of blue/white lightning charged in both of his hands.
"That's the last time you'll be saying anything like that..." Deviant whispered. With the blast of hatred echoing through the air, Mewtwo smiled with the feeling of the huge blast of lightning waiting to obliterate his body.
And with the crackle of thunder, Mewtwo caught his first glimspe of paradise waiting for him in the great beyond.
