Pikachu

Pikachu (ピカチュウ Pikachu) is an -type Mouse Pokémon introduced in Generation I that is the evolved form of Pichu. Pikachu is famous for being the most well-known and recognizable Pokémon in Generations I-V. Over the past years, Pikachu has become so popular that it serves as the Pokémon franchise mascot. In 1998, it became a Version Mascot for the game Pokémon Yellow. In the series, Ash's Pikachu had extremely strong powers, which is the reason Team Rocket is after it.

Appearance
Pikachu is a small, chubby rodent-like Pokémon which is covered almost completely by yellow fur. It has long yellow ears that are tipped with black. A Pikachu's back has two brown stripes, and its large tail is notable for being shaped like a lightning bolt. On its cheeks are two circle-shaped red pouches used for storing electricity, which turn yellow and spark with electricity when its about to use an attack such as Thunderbolt.

A female Pikachu looks almost exactly the same as a male with the exception of her tail. A female Pikachu's tail is rounded at the end and has an inward dent, giving it the appearance of a heart.

Like Pichu, Pikachu store most of their electricity within the red areas of their cheeks. You can see small surges of electric energy whenever a Pikachu gets protective, angry, etc.

Special Abilities
Pikachu's special ability is Static, which can cause paralysis in battle if hit by a physical move. In Pokémon Black and White's Dream World, the Trainer receives a Pikachu with the Lightningrod ability.

Evolution
Pikachu evolves into a Raichu by using a Thunder Stone. It evolves from Pichu when its happiness is maxed with the trainer.

Pokémon Adventures
In the Pokémon Adventures Manga, Red owns a Pikachu named "Pika" and Yellow also owns a Pikachu named "Chuchu".

Game Info
Pikachu is the main character in the game PokéPark Wii: Pikachu's Adventure

Super Smash Bros.
Pikachu has also appeared in all three Super Smash Bros. Series games. Pikachu is a very agile and mobile playable character. In Super Smash Bros., Pikachu was considered the strongest playable character. In Super Smash Bros. Melee, Pikachu's Skull Bash move was introduced, and its Quick Attack ability was upgraded so that it did a small amount of damage to opponents. Pikachu has also once again appeared in Super Smash Bros. Brawl as a playable character, with its exclusive attack Volt Tackle as its Final Smash. If you look at the hat Pikachu and you look at the shiny above and the hat, you would notice it's the Shiny Pikachu with Red's japanese hat.

Each of Pikachu's alternate forms in Brawl can be seen as a tribute to different Pokémon games; The blue goggles come from Pokémon Colosseum and the red hat comes from the Kanto region games while the green headband comes from Pokémon Emerald.

Along with Mario, Link, and Kirby, Pikachu is a mascot for the Super Smash Bros. series.

Design origin
Though not the first Pokémon created, Pikachu was the first "-type" Pokémon created, conceived after the type was suggested to Sugimori and designed around the concept of electricity and the common symbol for lightning.

Etymology
The name "Pikachu" is a portmanteau of the Japanese words "pikapika", an onomatopoeia for electric sparkling, and "chū", which is the Japanese onomatopoeia for a mouse's squeak. It may also be based on the pika, a mouse-like animal more closely related to rabbits but it's behavior (or more noticibally it's eating habits) resemble that of hamsters.
