Raichu is NOT the evolved form of Pikachu, but it IS the evolved form of Pichu. Raichu is an Electric-Type Pokemon. It first appeared in the Pokemon Red and Blue Shames. Later, it reappeared in every Pokemon shame ever since then. Electric-Type Gym Leaders always have a Raichu in their team. Raichu can always be seen in the Viridian Forest. Unlike normal electric Pokemon, Raichu is friendly and will only kill upon command, but idiots like Team Rocket train them to think they're Pikachu and be evil. Not very much is known about Raichu.
