わるいてぐせ

Whenever a move makes contact with this Pokémon, if it does not have a held item, it steals the attacker's held item. This Pokémon cannot steal upon being knocked out. It can steal if the attacker has a Substitute, but cannot steal when its own Substitute is hit. If a move hits multiple times, only the last hit triggers this ability. If this Pokémon is wild, it cannot steal from a trained Pokémon.
