The Sticky Barb (Japanese: くっつきバリSticky Barb) is a type of held item introduced in Generation IV. It is an in-battle effect item that damages its holder at the end of each turn.
At the end of the turn, the Sticky Barb damages the holder by 12.5% of its maximum HP each turn. If a Pokémon with no held item hits a Pokémon holding a Sticky Barb with a contact move, the Sticky Barb will transfer to the Pokémon that used the move.
