Mewtwo shakes off the Fire Blast and throws Ivy and Wart into Leon.
Mewtwo: I might need to take this just a little bit more seriously.
He transforms into his Pokémon form.
Mewtwo: Telekinesis: Psycho Spoon.
He condenses psychic energy into the shape of a spoon, turning the supportive move Telekinesis into an offensive one. He throws the spoon at Leon but he dodges it. The spoon curves back around to hit Leon in the back.
Mewtwo: The spoon never misses it's target.
He tries to hit Leon again but Otto drags him out of the way and Wart destroys it with Hydro Pump. Una wraps him with String Shot and even though he breaks out of it, Ivy has enough time to charge up and fire a Solar Beam. Rai uses Double Team to disorient Mewtwo. He releases another Psystrike to try and find the real Rai but he's no where to be found. Above him though is both Rai and Leon landing a Thunder and Fire Blast respectively.
Mewtwo: (There's too many attacking at once, I can't deal with all of them at the same time. I'll have to reduce their numbers.)
He reverts back to his Pokéman form to heal himself a little and uses Telekinesis again.
Mewtwo: Psystrike: Mind Shatter.
Mewtwo sacrificed the area of effect of the attack to condense it down to two attacks directly into the brains of Ivy and Una. The sheer force of the attack instantly dropping them both to the ground.
Mewtwo: That's two. Only you four left and this battle is over.
He switches back to his Pokémon form and creates four more giant spoons. He hits Rai and Leon but Wart uses Protect and Otto uses Fly to contain the spoon. Both Rai and Otto are hit with Disable as Mewtwo attempts to hit them with Psychic. Luckily, Wart and Leon get them out of the way in time.
Mewtwo: You fell for my trap. Psystrike: Mind Shatter.
Now in his Pokémon form, the attack is able to target all four of them. Though without Telekinesis, the attack is unable to automatically target the group and Otto, Wart, and Leon dodge the attack. Unfortunately Rai is knocked out.
Mewtwo: (Using such a powerful technique nearly twice in a row is bound to take a toll on me, but it shouldn't be this much. Something else is interfering with my strength.)
Otto throws Leon and Wart with Fly but Mewtwo grabs them with Psychic and throws them both back at her with double the force, knocking her out.
Wart: Leon, you wanna try the same thing we did against Lance?
Leon: I wish, but I don't think just the two of us would be able to pull off the same kind of output as before. If onky Ivy was still up.
Ivy: I am, just give me a quick second.
Surprisingly, Ivy barely survived the super effective Psystrike technique. Mewtwo looks down at his feet to see Ivy's Leech Seed entangling his feet.
Mewtwo: So this is what has been making me so weak.
He crumbles the plant and reverts to his Pokéman form.
Mewtwo: No matter now.
Leon: So you two ready?
Ivy: Mhm.
Wart: Yeah.
Leon: Alright, I'm gonna need you guys to put everything you got into this attack. Every last drop of water left in your tank Wart. The strongest roots you can muster Ivy.
Wart: And all the fire left in your soul Leon.
Leon: Yeah, let's do this. Blast Burn!
Wart: Hydro Cannon!
Ivy: Frenzy Plant!
Mewtwo: Psystrike: Mind Shatter!
Ivy's life force is being drained for this attack. Wart's blood is being shot out his cannons for this attack. Leon's flames burn a bright blue for this attack. The three attacks collide with the Psystrike technique but effortlessly break through it. Mewtwo is hit by their ultimate attack but manages to hold on to his last bits of consciousness. He tries to change his form over and over again but keeps failing. Both Wart and Ivy collapse from exhaustion. The last line of defense is Leon.
Leon: (I have to keep going. For everyone.)
Every step he takes fills him with excruciating pain. Blood is dripping from his ears and eyes from all the attacks his brain has faced. He makes it to Mewtwo but can't even lift his arms enough to hit him. Leon fall onto Mewtwo but catches himself before hitting the ground. Mewtwo however doesn't get back up.
Announcer: We have our new champions! This spectacular battle has came to an end with our team of Pokémen standing above the rest! Truely just successors to the Indigo League!
Leon collapses with a smile on his face.
