Thrash is an offensive Normal-type move. It can be considered a Normal counterpart to Outrage.
Thrash inflicts damage for 2-3 turns, at the end of which the user will become confused. It is disrupted if it is not successful due to missing, a status condition, or a target that could not be hit. (such as with a defensive move or a type immunity) If a disruption occurs on what would have been the final, confusion-inducing turn of Thrash, the user will still become confused. In double battles, the user selects itself as the target, but hits an opponent that is selected at random upon each use of the move.
