Ah the pikachu...the cute yellow pokemon from the pokemon series....#25 on the list it rox :)

Here is some facts bout the pikachu


Biology

Pikachu are ground-dwelling rodents with an affinity for electricity and lightning. They live in forests and plains, and forage for berries. The glandular pouches residing in its cheeks allow it to charge up and store electricity in chemical form, which it can discharge in bolts of lightning or ball lightning to defend itself from attackers (or attack its foe in a Pokémon battle), but it occasionally discharges electricity to roast a berry to make it tender enough to eat, or simply to keep from overloading. (An inability to discharge electricity in this last way, which is caused by a strong magnetic field, leads to a flu-like illness.) A swarm of Pikachu working together can generate intense electric shocks, and the electro-magnetic forces exerted by the electric field can even conjure a thunderstorm. Pikachu (also Raichu and Pichu) are smart and have good senses of eye sight, smell and hearing.
Pikachu is yellow with brown stripes on its back, black-tipped ears, red cheeks, and has a lightning bolt-shaped tail. It lacks a typical 'natural' evolution but can be evolved via Thunderstone into Raichu. However, Pikachu is so cute that in the anime and various manga, most trainers choose to keep it from evolving. In Pokémon Yellow , the Game Boy Color game featuring the "Electric Mouse", Pikachu refuses to evolve: attempting to use a Thunderstone on it makes it cry and refuse. It is numbered as #25 in the National Pokédex. Also, in the second and third generations of the Pokémon games, Pikachu has an evolutionary predecessor, Pichu. Pichu, a baby Pikachu, evolves into Pikachu after establishing a friendship with its trainer.
A Pikachu's tail, which it often raises into the air to distract predators or attract other Pikachu, is an excellent conductor, to the point where a Pikachu can suffer lightning strikes to its tail without any difficulty. A Pikachu can ground out electrical attacks to its body with its tail.

Ash Ketchum's Pikachu

In the Pokémon anime, Pikachu was Ash Ketchum's first Pokémon. In the first episode of the Pokémon anime, Pikachu did not like Ash and shocked him with electricity every time Ash came near. However, by the second episode, Ash demonstrated his willingness to sacrifice himself for Pikachu, and they became fast friends. Pikachu established its dislike of being confined in a Poké Ball, and prefers to travel alongside Ash. In another first season episode (in Vermillion City), Pikachu, who is often rather independently minded, believed that it was strong enough without evolving and refused to evolve into a Raichu. In fact, in Ash's third gym battle in Vermillion City, Pikachu was successful in defeating a Raichu. To this day, Ash's Pikachu has partcipated in more gym battles than any of his Pokemon.
Early in the series, Pikachu was given an operation to increase the strength of the electric sacs in his cheeks in order to beat the first gym leader, Brock. Despite this, Pikachu can also get a cold and go out of control when it cannot release its electricity. Most notably, exposure to a magnetic field will cause Pikachu to get a cold. This has been done to Pikachu twice in the series, both times by Team Rocket: the first time, Pikachu was cured when the extra electricity was used in attacks against a group of Grimer and Muk, and in the second time, Pikachu was inadvertently cured by one of Team Rocket's battery robots, which subsequently overloaded and exploded. During the Hoenn arc, Ash trained Pikachu to use Iron Tail, which greatly improved its ability to fight Pokémon with resistance to Electric attacks. Several interesting storylines involving Pikachu are in "Pikachu's Goodbye" where Ash nearly released Pikachu into the wild to be with other Pikachu, Pikachu losing his memory in the final chapter of the Hoenn adventures and it temporarily joined Team Rocket, Pikachu getting injured at the beginning of the Hoenn arc and later getting corrupted by the recently-awakened Groudon.
Pikachu is the only Pokémon in Ash's huge party that has been with him in every series, although a Donphan he rose from an egg joined him after he travelled around Hoenn. It is implied that Ash's Pikachu is male, but it is rarely addressed with a gendered pronoun. Also, many times Ash and Pikachu have been separated by cave-ins and explosions. Most of those times Meowth is separated from Team Rocket too, and they usually end up working together to find their trainers.

Opening titles for the Pikachu animated short, "Pichu and Pikachu" featured before Pokémon 3: The Movie.
Many of the Pokémon animated shorts with all-Pokémon dialogue have featured Pikachu as the main character, often as the main voice of reason. As such, Pikachu is often a leader, helping to break up conflicts among other Pokémon. In the second Pikachu Movie, it is revealed Pikachu lived in a large tree with many friends including an Elekid, a Snorlax and a trio of dancing Bellossom.
Pikachu typically eats a specially formulated pellet made by Brock. It also prefers fresh fruit, especially apples. Sometimes it is shown eating the same meal that his human companions are eating, in smaller portions. If ketchup is available on the table it would most often partake of it. In one case Ash's Pikachu kept the bottle and became slightly obsessed with it. This caused problems because a Scyther and an Electabuzz that were enraged at the color red were nearby.
Like most other Pokémon, Pikachu communicates only by saying syllables that are in its own name. Its most common sentence is "Pika-pika". When it wants to talk to Ash it says "Pika-pi," which sounds similar to "Satoshi", and calls Misty "Pikachupi" similar to her Japanese name of "Kasumi". It refers to Togepi as "Pipipi", probably because in Japanese, "pii" means "little". Pikachu is voiced by Ikue Otani in all versions of the anime, except in the first episode, entitled "Pokémon, I Choose You!", in which Rachael Lillis, the regular voice of Misty and Jessie of Team Rocket, provided the voice in cases where another character's voice overlaps Pikachu's

Other Pikachu
In the Pokémon anime, many other Pikachu have also appeared. The most notable among these is Richie's Pikachu, with mussed hair on its forehead. This one is nicknamed Sparky (Leon in the Japanese original). Sparky, unlike Ash's Pikachu, is indifferent to being inside its Poké ball, but it is almost always shown outside, similar to Ash's Pikachu. In fact, every captured Pikachu in the anime has been shown spending most or all of its time outside of a Poké ball, even though this is not noted by any characters to be typical of the species.
Another notable Pikachu one named Puka (Michael in the Japanese version), a surfing Pikachu owned by a surfer named Victor. Puka has blue eyes instead of the usual black and also seems to have a harmony with the sea, and it's said that it glows a bright blue when it feels a powerful wave. Puka is over 20 years old (it is unknown whether such longevity is unusual for a Pikachu), and is noticeably larger than Ash's Pikachu (though still smaller than a Raichu). It also has somewhat frazzled hair on around the tips of its ears, which is probably a sign of its age (in a flashback to 20 years earlier, Puka is shown without this trait).
Many episodes of the anime have also featured other unnamed Pikachu. Among them is "Pikachu's Goodbye", in which a large group of wild Pikachu appeared, and in "Pokémon Emergency", a group of Pikachu are always hidden in the Viridian City Pokémon Center as their very own "Pika-Power Source", which was used when Team Rocket cut the power to the center. The footage of these Pikachu is later reused for a group of Pikachu aboard the SS Anne.
There is also an episode in which Ash is himself magically transformed into a Pikachu for the last few minutes. Pikachu tickles Ash, and the episode ends. In the following episode, Ash is still a Pikachu, but reverts to human form before the episode's actual plot starts. This form of Ash is nicknamed by some as "Satochu", a portmanteau of "Satoshi" and "Pikachu".
In general, Pikachu in the anime (including Ash's Pikachu) have only had their tails shown from the flat side, never its "razor side". Why this is, is never explained, but it may be merely because they're coincidentally drawn from particular angles only.


Cultural Impact
The phrase "Pika-pika" is often considered funny, particularly to Japanese speakers' ears. The Japanese expression "pika-pika hikaru" means stroke of lightning; it is also used to denote a small bald spot on the very top of the head still surrounded by hair. "Pika-pika" can also mean "shining" or "shimmering" and denotes the electric element of Pikachu.


so as you can see from the huge facts here...the pikachu is not dead...and will never be...the pikachu is staying here now until forever..it will remain as a timeless enjoyment of cuteness to children, teens and even some adults....so the word "pika-pika" is already forever immortalised in the language of the world...


so ppl stand up, and just say Pika-pika, cause its here to stay :)
