Design and characteristics

Pikachu are small, mouse-like Pokémon that have short, yellow fur with brown markings covering their backs and parts of their tails. They have black-tipped, pointy ears and red circles on their cheeks, which are said to contain "electrical sacs".[3] Their tails are shaped in the form of a lightning bolt.[12] In Pokémon Diamond and Pearl, gender differences were introduced for some Pokémon; a female Pikachu now has an indent at the end of its tail, giving it a heart-shaped appearance.

The Pokédex, in the series, states that Pikachu forage for berries, roasting them with their electrical attacks before eating.[13] For already fallen berries and apples they use their electricity to roast and tenderize them. They are said to store electricity in their cheeks,[3] and by simply squeezing them they can discharge sparks, lightning bolts, or other forms of electricity. Discharging sparks and thunderbolts may be a sign of wariness from the Pokémon. An inability to discharge electricity, as occurs in the presence of a strong magnetic field, causes an illness with flu-like symptoms. Pikachu tend to gather in areas with high amounts of thunderstorm activity. When threatened, a group of Pikachu can generate an intense electrical output, and the electro-magnetic forces exerted by the resulting field can even produce short-lived, localized thunder and lightning storms.[14] They occasionally use an electric shock to recharge a fellow Pikachu that is in a weakened state.[15]

Pikachu evolves into Raichu via the use of a Thunder Stone; however, it is somewhat common for trainers to choose not to evolve their Pikachu. In the Pokémon Yellow game, using a Thunder Stone on a Pikachu makes it cry and refuse to evolve. From the second generation of the Pokémon games onward, Pikachu has an evolutionary predecessor, Pichu, which evolves into Pikachu after establishing a close friendship with its trainer.
