Pokémon Bank may not have had the most auspicious of starts, with the success of its festive launch in Japan causing the infamous Nintendo Network Christmas meltdown of 2013, but it's become an integral part of the Pokémon experience. For a relatively small annual fee ($4.99 in the US, for example) players can store their 'mon in the 'cloud' and move them between games, which are certainly neat features to have.
Ahead of a big year for the series, in which the service is supporting the gen one Virtual Console games and eventually Pokémon Sun and Moon, there's a promotion to encourage players to sign up. Those that access the service will receive special versions of Regirock, Regice, and Registeel that can then be used in Pokémon X & Y in addition to Pokémon Omega Ruby and Alpha Sapphire. They have a hidden ability each, making them unique from their ORAS equivalents.
Below are the details from the official website:
With the Hidden Ability Sturdy, if Regirock has full HP and is hit with an attack that would normally knock it out, it will be able to endure the hit with 1 HP remaining. This is a great Ability for Regirock to have, being a Rock type with many weaknesses.
Regice's Hidden Ability Ice Body allows it to restore HP when the weather condition is hail. Regice is strong against opponents that attack it with special moves. By using Hail, it can recover HP throughout the battle while doing even more damage!
Ability: Ice Body
Registeel's Hidden Ability Light Metal reduces its weight by half. This decreases the damage it will take from moves such as Low Kick and Grass Knot that are more powerful the heavier the target is. It is especially good for Low Kick, a Fighting-type move that is super effective against the Steel-type Registeel. Roll with those supereffective punches and strike back!
Ability: Light Metal
Moves: Iron Head
These will be available once the bank is accessed between 4th March and 31st October. Will you be claiming them?
