Drake's Ditto was a Ditto that was used by Drake of the Orange League. Drake uses this Pokémon first to unnerve his opponents by transforming into a copy of their first Pokémon and throw them off their game. In Ash's battle it copied Pikachu, however it was no match for the real McCoy and was soundly defeated.
Trivia
- In the English Dub, Drake made a pun about his Ditto saying it'll "Leave a good impression."
