Mewtwo, the legendary Psychic-type Pokémon from the original Kanto region, is one of the most powerful and iconic characters in the entire Pokémon franchise. Many fans have long wondered if it’s possible to breed a Mewtwo using Ditto in Pokémon Sword & Shield. Fortunately, the answer is yes – although it's not as simple as most other Pokémon breeding processes.
The main problem with breeding Mewtwo with Ditto is that most of Mewtwo’s genes are unbreedable. This means that even when paired with a female or male compatible partner - in this case, an ever versatile Ditto - the process will still not be successful as they cannot create offspring similar to themselves due to their genetics being incomplete. That doesn't mean you can't try though! If you have both a female and a male compatible partner, then you may still be able to successfully breed them together.
To do so, take your two Pokémon over to the Day Care Center near your home town and talk to the NPC there who'll help get everything set up for you. The egg hatching process for Mewtwo takes roughly five hours once placed into an Incubator, after which point you should find out what type of creature hatches out of it! Overall, while breeding a Mewtwo using Ditto isn’t quite as straightforward as breeding other Pokémon species in Pokemon Sword & Shield – it is still possible under certain circumstances. By gathering both a female and male compatible partner for your pair and following all necessary steps correctly, there’s no reason why you shouldn’t be able to witness some unique results!
