In link battles, battle facilities, Secret Bases, and the Trainer House, items stolen will be returned at the end of the battle.
Generation V onwards
Switcheroo no longer switches a Trainer's Pokémon's items permanently; however, items switched in wild battles are permanently switched.
Switcheroo can now exchange a Griseous Orb as long as neither the user nor the target is Giratina. Switcheroo fails if the user or the target is Arceus when either Pokémon holds a Plate (Multitype has no effect on Switcheroo), if the user or the target is Genesect when either Pokémon holds a Drive, if the user or the target is holding a Mega Stone or a colored orb that could allow either Pokémon to undergo Mega Evolution or Primal Reversion, if either Pokémon is holding Mail or a Z-Crystal, or if the user or the target is Silvally and either Pokémon is holding a memory.
If powered up by a Darkinium Z into Z-Switcheroo, the user's Speed stat is raised two stages.
