Finally, Mewtwo thinks, Isolation. Complete and utter isolation. Mewtwo sits upon its rock in Cerulean Cave meditating.
Suddenly, there is a blast that rocks Mewtwo's concentration. Mewtwo opens its eyes, annoyed. A young Trainer runs in with a Charizard at its side.
"Look!" The trainer yells pointing at Mewtwo. "There it is!"
Mewtwo frowns. "Begone with you!" Mewtwo says using telepathy. The Trainer just smiles and pulls out a purple Pokéball with an M on it. The Master Ball.
Mewtwo scowls and sends a shockwave of psychic energy at the attacker. The Trainer strains to stay upright. He throws the Master Ball.
Mewtwo conjures a psychic spoon and smashes the Master Ball. The Trainer stares at the pieces in horror.
"Bu…bu…bu…wha?!" The Trainer mumbles hysterically. He looks up at Mewtwo. The incredibly powerful Psychic Pokémon looms over him menacingly.
The Trainer scrambles to get away. Obviously he didn't want an actual fight. Mewtwo is pretty ticked off. He uses Psystrike to completely annihilate the trainer and the Charizard.
Mewtwo settles back onto its rock to meditate again.
Finally, Mewtwo thinks, Isolation. Complete and utter isolation.
