Today Nintendo is starting what will be a three week special distribution for Pokémon Omega Ruby and Alpha Sapphire that will feature the final evolved forms for the three starters from Pokémon Black and White. For the next three weeks a different starter will be given out and will be available until November 30th.
Starting today Pokémon fans can obtain Serperior, next week on January 29th Emboar will be available, and finally on February 5th Samurott will be given out. All three of these Pokémon come with a Hidden Ability and can be obtained through a special password, that will need to be entered into the Mystery Gift section of the game, which is being given out either through the Pokémon website or through the Pokémon Trainer Club newsletter.
That being said, this week’s special code for Serperior happens to be very easy to remember, as it is Serperior’s Pokédex number POKEMON497.
