Pika = Electric
Chu = Mouse

1. Pikachu is an electric mouse found in the games, tv show, and movies of Pokemon.

2. The very reason why the show Pokemon shouldn't be aired anymore, in english... edited... Because the show has been KIDDYORIZED to attract small children, instead of the intended audiences of Early teens.
I really hate that Pikachu.
Pikachu, GO!
Oh yes Pikachu, harder!
That damn Pikachu shocked the hell out of me!

1. A creature from the animated series Pokemon (Pikachus themselves are Pokemon). Pikachus are defined as yellow mouse-like animals, with tails in the shape of lightening bolts. They harness the power of electricity.

The Pikachu expresses itself through emotionally emphasizing the word "Pikachu" and various pieces of it (e.g. "Chu" or "Pika"). Pikachu is evolved from the pokemon Pichu, and may evolve into a Raichu.

2. A recurring character in the Pokemon animated series. The lead character, Ash, is given Pikachu in the first episode. He later finds that, unlike other pokemon, Pikachu will not enter a pokeball.

Pikachu is voiced by Ikue Otani. It is often conisdered the most popular character of the Pokemon series, and has become a well known symbol of the show.

A misunderstood yellow rat-like creature that often shows up on the show pokemon. We can all agree that if he wasn't portrayed in a manner that looked like a 4-year old's imagination and if people could actually understand what he was saying, his cool points would total around that of Nickelback. His abilities include emitting powerful electric shocks. Recenlty he has attempeted to get his name changed to Brandon.
"Pika Pika!"

"Pikachu says that he hates the director of pokemon and would like to take a shotgun to his head."

The lead Pokemon character in the Anime of Pokemon. An electric mouse Pokemon.
It is described in different ways in different Pokemon games and are as follows:

Red/Blue: When several of these POKéMON gather, their electricity could build and cause lightning storms.
Yellow: It keeps its tail raised to monitor its surroundings. If you yank its tail, it will try to bite you.
Gold: This intelligent POKéMON roasts hard BERRIES with electricity to make them tender enough to eat.
Silver: It raises its tail to check its surroundings. The tail is sometimes struck by lightning in this pose.
Crystal: When it is angered, it immediately discharges the energy stored in the pouches in its cheeks.
Ruby: Whenever PIKACHU comes across something new, it blasts it with a jolt of electricity. If you come across a blackened berry, it's evidence that this POKéMON mistook the intensity of its charge.
Sapphire: This POKéMON has electricity-storing pouches on its cheeks. These appear to become electrically charged during the night while PIKACHU sleeps. It occasionally discharges electricity when it is dozy after waking up.
Emerald : It stores electricity in the electric sacs on its cheeks. When it releases pent-up energy in a burst, the electric power is equal to a lightning bolt.
Ash: Go! Pikachu!!

That Pokemon named Pikachu is soooo cute. =3

Just like other japanese pokemon names, the word Pikachu has a childish meaning from onomatopeic expressions such as girigiri and pikapika. Pika is taken from the sound of sparks or the effect of something being shiny. Chu is the sound a mouse makes as well as a kiss. Easy for children to remember and understand. Pikachu is an electric mouse pokemon, although he looks like a rabbit squirrel tiger with cockatiel cheeks. He popularized pokemon and is the main mascot of the show in the united states. Much more popular now that in japan as now japan has been taken over by battle beatles. Some people want him to die and some want to make love to him. I thought he was cute when I was 12.
Pikachu fainted. Let's eat him.
