Pokémon: The First Movie/Tear Jerker

• If you ever seen the short, then it's absolutely gut-wrenching for Mewtwo to lose his only human companion (who was a clone of Dr. Fuji's daughter), what makes this tragic is that he lost his memories of her right after she dies.
  • After Dr. Fuji's stupid moment when he tells Mewtwo he's an experiment, Mewtwo destroyed the lab in his very pissed off moment. Not only has he kills the scientists and the lab, but he also destroyed what's left of Amber/Ai.
