[[File:Duplica`s_ditto2.jpg|thumb|left|Ditto's little problem.]] Ditto is Duplica's partner Pokémon. It can copy any Pokémon it goes up against. At first it had a slight problem: Every time it copies a Pokémon, Ditto always kept its own face. It was captured by Team Rocket to be transformed into a Dratini. However it has a little fun at Jessie's expense. After being threatened it molded it's face into Meowths when it imitated it, a perfect match. After a touching moment, Team Rocket "gave" Ditto back but Duplica could tell it wasn't Ditto. After getting it back Duplica and Ditto said their goodbyes to Ash and co.

It appeared again in [[JE058: Imitation Confrontation]], along with Mini-Dit, it's "little brother".
