A splicer that fuses Kyurem and a certain Pokémon. They are said to have been one in the beginning.
This item did not appear in any previous games.
The DNA Splicers is a key item that allows the player to merge Kyurem with either Zekrom or Reshiram into Black Kyurem or White Kyurem, depending on version. Once the merge is complete, the pin can also be used to revert Black Kyurem or White Kyurem into two separate Pokémon. It works with both groups (Reshiram and Kyurem, Zekrom and Kyurem) in both games. You cannot use it on two Kyurems in one game(cannot create both Black Kyurem and White Kyurem within one game) Game of Origin: Pokemon Black 2 and Pokemon White 2. It is dropped when the player catches Kyurem in Giant Chasm.(The DNA Splicers will remain there until the player picks it up)
