Pickup

Pick Up is an ability that allows the user to collect items after battle if it is not already holding one. After a battle, if the Pokémon with Pick Up is not holding an item, it has a chance to find and pick up an item that was used or dropped by other Pokémon during the battle. The items that can be picked up vary depending on the level of the Pokémon with Pick Up. This ability is found on a few different Pokémon, mostly normal types and Alolan Meowth.

In battle, at the end of each turn, if your Pokémon has no held item and the opponent used an item that turn then Pick Up will steal it!
