Pikachu (Japanese: ピカチュウ Hepburn: Pikachū?) (/ˈpi kətʃu /; pikatɕu͍ ) are a species of Pokémon, fictional creatures that appear in an assortment of video games, animated television shows and movies, trading card games, and comic books licensed by The Pokémon Company, a Japanese corporation. The Pikachu design was conceived by Atsuko Nishida and finalized by Ken Sugimori. Pikachu first appeared in Pokémon Red and Green in Japan, and later in the first internationally released Pokémon video games, Pokémon Red and Blue, for the original Game Boy.

Like other species of Pokémon, Pikachu are often captured and groomed by humans to fight other Pokémon for sport. Pikachu are one of the most well-known varieties of Pokémon, largely because a Pikachu is a central character in the Pokémon anime series. Pikachu is regarded as a major character of the Pokémon franchise as well as its mascot, and has become an icon of Japanese pop culture in recent years.

Epic yellow object made from Chuck Norris's guts and Charlie Sheen's blood. A living Tesla Coil. If his lightning was projected in real life, it would be around a hundred million volts, and a few hundred amps. AKA Deadly but awesome. Pikachu hates going into Pokeballs, and controls children's minds through it's total epicness. A male pikachu has a pointy tail, and a female has a heart. Pikachu is the god of adorable, fluffy things and is an apprentice for the god of high voltage, Nikola Tesla. Pikachu might cause seizures when zapping missiles though. Other than that, a tame one is extremely cuddly. Pikachu lost a lot of weight from the first season to now. That doesn't mean he's any less adorable and cute!
Today's kids will never know why Pikachu is always out of its pokeball... Pikachu, Plusle, Minun, Pachirisu, and Emolga are all related, according to Bulbapedia. Also, you can tell by looking at them. They all have circles on their faces, and they are all tiny, and they are all cute as fuck.

Joke: What is an electric Pokemon's capacitance measured in?

PIKA-FARADS!!!
