Though not the first Pokémon created, Pikachu was the first "Electric-type" Pokémon created, conceived after the type was suggested to Sugimori and designed around the concept of electricity and the common symbol for lightning.[7] The name is a portmanteau of the Japanese words pikapika, an onomatopoeia for electric sparkling, and chū, which is the Japanese onomatopoeia for a mouse's squeak.[8]
