Pikachu

"Pika, pika!"

- Pikachu's famous expression

Pikachu (ピカチュウ, Pikachu) is the iconic mascot and deuteragonist from the Pokémon franchise. It is an Electric-type pokemon that resembles a mouse. He is played by Ikue Ohtani.

Pikachu evolves from Pichu by leveling up with max happiness. Pikachu evolves into Raichu if given a Thunder Stone.

Biology
Pikachu is a short, chubby rodent Pokémon. It is covered in yellow fur, and its ears are long and pointed with black tips. It has a small mouth, brown eyes, and two red circles on its cheeks. There are pouches inside its cheeks where it stores electricity. Its forearms are short, with five fingers on each paw, and its feet have three toes. It has two brown stripes on its back, and its tail is in the shape of a lightning bolt with a patch of brown fur at the base. A female will have a V-shaped notch at the end of its tail, which looks like the top of a heart. It is classified as a quadruped, but it has been known to stand and walk on its hind legs.

In "Pikachu's Goodbye", it is shown that Pikachu sometimes travel in groups. It raises its tail to check its surroundings, and is occasionally struck by lightning in this position. Living in forested areas, Pikachu is found foraging for berries it roasts with electricity to make them tender enough to eat. It has been observed eating and sometimes destroying telephone poles, wires, and other electronic equipment.

Pikachu is able to release electric discharges of varying intensity. Pikachu has been known to build up energy in its glands, and will need to discharge to avoid complications. It is also able to release energy through its tail, which acts as a grounding rod, as well as recharging fellow Pikachu with electric shocks. Pikachu can also electrify itself to use its signature move, Volt Tackle. When threatened, it looses electric charges from its sacs, and a group can build and cause lightning storms. It is found mostly in forests, where a sure sign that Pikachu inhabits a location is patches of burnt grass.

Pikachu (Anime)

Pikachu (Super Smash Bros. Series)
Pikachu has appeared in every Smash Bros. Game. In Super Smash Bros. Brawl, he knows some very powerful attacks. His Final Smash is called: "Volt Tackle"

Origin
Pikachu has physical aspects of several species of rodents, and its species name suggests that it is based on a mouse(Although is still arguable as it's sometimes said to be a cat). It is not particularly similar to the pika despite its name, but its long ears do resemble those of other members of Lagomorpha. The rodent that Pikachu most resembles is the Viscacha, a type of chinchilla that lives in the desert.

Name Origin
Pikachu is a combination of ピカピカ pikapika (onomatopoeia for sparkle) and チューチュー chūchū (the sound of squeaking). Pikachu was designed by Atsuko Nishida, a member of the core design team at Game Freak.
