"We dreamed of creating the world's strongest Pokémon...and we succeeded."
Dr. Fuji realizes what he has unleashed.
Mewtwo: That cannot be. You said we were partners. We stood as equals.
Giovanni: You were created by humans to obey humans. You could never be our equal.
Mewtwo: Humans may have created me, but they will never enslave me! This cannot be my destiny!
Giovanni: (as Mewtwo begins destroying the lab) Stop this now!
Mewtwo: I wasn't born a Pokémon, I was created; and my creators have used and betrayed me! So, I stand alone!
(Mewtwo blows up the laboratory)
Giovanni learns the hard way how powerful his creation is.
Brock: "I didn't know Vikings still existed."
Ash: "They mostly live in Minnesota!"
Ash and Brock make a football joke.
"What? Pokémon can't be Pokémon masters! No way!"
Fergus is shocked by the idea that Mewtwo was the one controling the Pokémon clones.
"Your Charizard is poorly trained."
Mewtwo makes a fairly obvious observation.
"Ow! Let go! UGH! Stupid machine! UGH! GIVE ME BACK MY...PIKACHU!"
—Ash, while struggling against Mewtwo's cloning machine in an attempt to save Pikachu, including taking "Chewing the Scenery" quite literally.
—Pikachu, after trying to revive him after his petrification.
"We do have a lot in common. The same Earth, the same air, the same sky. Maybe if we started looking at what's the same instead of what's different... well, who knows."
Meowth philosophizes on if clones are considered natural.
"The human sacrificed himself, to save the Pokémon. I pitted them against each other, but not until they set aside their differences did I see the true power they all share deep inside. I see now that the circumstances of one's birth are irrelevant; it is what you do with the gift of life that determines who you are."
