For October 2025, the elusive Pokémon Ditto only appears disguised as other creatures in Pokemon GO, making it hard to find unless you know its cover.
Even if the Pokémon seems mundane or weak, if it’s one of the disguise species, you must catch it. That’s the only way to reveal if it’s Ditto.
If you’re into the breeding side of Pokemon games, you know that there’s one Pokemon more important than any other, Ditto. If you’re looking to find one, however, it’s gonna take a bit of work.
