Pokémon: The First Movie1998

Ash:
We've got to stop this.

Brock:
But how? All Mewtwo cares about is proving how strong those super-clones are.

[Mew and Mewtwo continue to fight up above]

Nurse Joy:
I'd rather risk my life out in Mewtwo's storm than watch these Pokémon destroy each other.

Misty:
Oh, me, too!

Nurse Joy:
I wish there was some way to stop them. I don't know what to do!

[Ash's Charizard and its clone collapse in exhaustion]

Brock:
I don't think they'll ever stop. Those Pokémon look like they're ready to fight to the death.

Misty:
That's a fight that nobody's going to win.

Ash:
Someone's gotta take a stand. Someone's gotta say "no", and refuse to fight... just like Pikachu.

[Pikachu's clone, exhausted from hitting Pikachu again and again, collapses into its arms]
