Unaffected by item negating effects (such as Embargo and Klutz). Item manipulating effects (such as Trick and Fling) cannot give Slowbro a Slowbronite or remove a Slowbronite from Slowbro.

Outside of battle

If held by a Slowbro, allows it to Mega Evolve into Mega Slowbro when it performs a Spectacular Talent during a Pokémon Contest Spectacular while its Trainer has a Key Stone. Slowbro will remain a Mega Slowbro until the Talent Round ends.

Pokémon holding Slowbronite in Pokémon Omega Ruby and Alpha Sapphire cannot be traded to Pokémon X and Y.
