Pikachu is the global mascot of the Pokemon franchise and one of the most recognizable fictional characters in the world. This Electric-type Pokemon, classified as the Electric Mouse Pokemon at Pokedex number 025, was created for the original Pokemon Red and Green games released in Japan in 1996. While Pikachu was not originally intended to be the series mascot (Clefairy was initially favored), the character's popularity in the anime series, where it serves as protagonist Ash Ketchum's devoted partner, propelled it to become the face of the largest media franchise in history, with lifetime revenues exceeding $100 billion. Fellow gaming icon [Mario](/quiz/mario/) is the only character who rivals Pikachu's cross-generational recognition.
In the Pokemon anime, Pikachu's story begins when a young Ash Ketchum oversleeps on the day he is supposed to receive his first Pokemon from Professor Oak. With all three traditional starters (Bulbasaur, Charmander, and Squirtle) already claimed, Ash receives a stubborn, uncooperative Pikachu who refuses to enter a Poke Ball. Their rocky start evolves into one of the most iconic partnerships in animation history. A defining moment comes early in the series when Pikachu defeats Lt. Surge's Raichu, proving that it can match its evolved form through determination and bond with its trainer rather than raw power. This moment establishes the anime's central theme and Pikachu's refusal to evolve.
Pikachu's design has evolved significantly since its 1996 debut. Originally drawn as a much chubbier, rounder creature by designer Atsuko Nishida (with finalization by Ken Sugimori), Pikachu was gradually slimmed down over generations to its current sleeker appearance. The Gigantamax form introduced in Pokemon Sword and Shield pays homage to the original chubby design. Pikachu's key physical features include its yellow fur, lightning-bolt-shaped tail, red electric pouches on its cheeks, and pointed ears with black tips. A gender difference was introduced in Generation IV, with female Pikachu having a heart-shaped indent at the tip of the tail.
Beyond the main games and anime, Pikachu has appeared across virtually every branch of Pokemon media. It has been a playable character in every Super Smash Bros. game since the N64 original, where it is consistently ranked among the stronger fighters. The Detective Pikachu video game and 2019 film (starring Ryan Reynolds as the voice of a wise-cracking, coffee-drinking Pikachu) demonstrated the character's appeal in live-action. Pikachu is the centerpiece of the annual Pikachu Outbreak festival in Yokohama, Japan, where hundreds of Pikachu performers parade through the streets.
Pikachu's cultural impact is unmatched in gaming. It has been featured on Japanese government aircraft, appeared in Macy's Thanksgiving Day Parades, been referenced in countless other media, and is recognized by people who have never played a Pokemon game. The Illustrator Pikachu trading card is one of the most valuable collectible cards in existence, selling for hundreds of thousands of dollars. Voice actress Ikue Otani has provided Pikachu's iconic voice in the anime since the very first episode in 1997, and her "Pika pika" has become one of the most recognized sounds in entertainment.
