Electivire is the evolved form of rock and roll Electric Pokémon, Electabuzz. Getting Electivire is pretty involved – like Rhyperior, you'll need to defeat the Pokémon Champion. Somehow, this will prompt new Pokémon to move into the Sinnoh region, and by inserting a FireRed cartridge into the GBA slot you'll encounter Elekids in certain areas. One in eight of these Elekids will be holding a mysterious item, the Electirizer. By evolving Elekid into Electabuzz and trading it while holding the Electirizer, it'll finally evolve into this yellow electric yeti. With impressive stats and the new Normal-type attack, Giga Attack, Electivire's a force to be reckoned with.
