Pokémon: The First Movie - Mewtwo Strikes Back

When humanity actually tries cloning a god, it goes about as well as you'd expect. Team Rocket's boss Giovanni commissions the creation of Mewtwo using DNA from the mythical Pokémon Mew, and the result is a being powerful enough to level buildings but deeply confused about why it exists. Mewtwo doesn't take kindly to being treated as a lab experiment, breaks free, and starts plotting against humanity from a remote island. The setup is classic villain origin story stuff, but then it gets surprisingly thoughtful for a kids' movie. Ash, Misty, Brock, and a handful of other trainers get lured to the island under the pretense of a battle challenge, and what they walk into is way heavier than a standard Pokémon fight. The film digs into questions about identity, what makes a life "real," and the ethics of cloning — themes you don't usually associate with a franchise about catching cute creatures. The soundtrack does a lot of heavy lifting emotionally, and Mewtwo itself became one of the most iconic characters in the entire Pokémon universe for good reason. If you grew up with Digimon Adventure: Our War Game or Dragon Ball Z: The World's Strongest, this hits that same nostalgic sweet spot of animated movies that were doing more than they needed to. It's a 1998 movie that still holds up, partly because those core questions about purpose and belonging never really go out of style.
