Pikachu is a small rodent with yellow fur and two brown stripes on its back. Its ears end in black, its red cheeks store electricity, and a female’s lightning-bolt tail ends in a V.
Curious and playful, it roasts Berries with its electricity and lives in groups in distant forests. Their tails touch as a greeting; when angry, it releases energy as strong as lightning.
Ash’s Pikachu, received from Professor Oak, stays outside its Poké Ball. It remains his partner from the original series through Pokémon Journeys, movies included, and can Gigantamax.
Its name comes from pikapika, the crackle of electricity, and chūchū, a sound that stresses how cute it is. Ken Sugimori is also said to have named it after a childhood sweetheart’s hamster.
