I think the idea that Pokémon are "real" is more about the emotional and cultural impact they've had on people. They're not flying around in the sky, but they've become part of our shared imagination. If I had to pick one, I'd go with Pikachu — not because it's the strongest, but because it's the one that's always there, loyal, and kind of stubborn. It's the kind of companion you'd want by your side through all the ups and downs.
