File this under “huh.” Ever wondered what “Pikachu” actually means? Sure, you have! “Pika” is from pikapika, which means to sparkle or glitter. “Chu” is from chuchu, the Japanese word for the sound mice make. So put them together, and you get “Pikachu,” AKA “Sparkle Mouse Noise.” A shame the localizers stuck with the Japanese original. We quite like that Sparkle Mouse Noise moniker.

Pikachu kinda means electric-mouse or sparking-mouse in this context, with the emphasis being on minor electrical presence in the context of its noise.
Pikachus evolved form is Raichu, Rai(雷) being the Japanese/Chinese word for thudner.
