When this move is used, if the user faints, the Pokémon that landed the knockout hit also faints.
When Destiny Bond is used, if the user faints as the direct result of an attack, the Pokémon that landed the knockout hit also faints. A Pokémon defeated by this move will faint before the Pokémon which used Destiny Bond. If it faints later than that (unless it used this move again), this move's effect will not happen. Destiny Bond does not activate for damage that occurs at the end of the turn, including damage from Leech Seed and Future Sight. In a double battle, both opponents are targeted, but only the one that knocks the user out is affected. In a double battle, if the partner Pokémon causes the Pokémon using Destiny Bond to faint, the partner Pokémon will not be affected.
