A couple of days ago, someone sent me a link to a YouTube video notifying others that cloning Pokemon in Pokemon X/Y with Poke Bank is possible. The video’s contents did not reveal what was done to clone the Pokemon, however, the information was already available on the Internet via Reddit post.
How To Clone Pokemon with Poke Bank in Pokemon X/Y :
- Back up save file using your Datel Powersave for 3DS.
- Store the Pokemon you want to clone in Poke Bank.
- Restore the save file to get back the Pokemon in your X/Y game.
- Go to Poke Bank and take back the cloned Pokemon.
