The Pokémon Company and Nintendo have a special surprise for Pokémon Bank users, in the form of the Hoenn Legendary Pokémon Regirock, Regice and Registeel.
Regirock will have Sturdy as a Hidden Ability, allowing them to survive an attack that would normally cause them to faint from a full health bar.
Regice will have Ice Body, restoring health when the weather has Hail status.
Registeel will be made lighter with Light Metal, meaning attacks that cause more damage to heavier foes will have less of an effect on the Steel legendary.
In order to receive the buffed legendary trio, Pokémon Bank users must use Pokémon Link in Pokémon X, Y, Omega Ruby or Alpha Sapphire after using Pokémon Bank through one of the aforementioned games, between 4 March and 31 October, 2016.
