Thief is a Dark-Type move introduced in Generation II. The user steals the Hold Item of its target whilst attacking it at the same time, provided the target is using a Hold Item. The user can't steal hold items if it has a hold item already, and the move fails if the target has the Sticky Hold Ability.
In trainer battles, the opponent's Hold Item is only taken temporarily.
