Pichu

Pichu is an Electric-type baby Pokemon. It evolves into Pikachu with high friendship.

Biology
Pichu is a small, ground-dwelling rodent Pokémon with pale yellow fur. Its eartips, collar, and tail are black and angular. Pichu's pink cheek pouches can store small amounts of electricity, and its tiny nose looks like a dot. Pichu is classified as a quadruped, but it can walk easily on its hind legs. Pichu is a social Pokémon known for its playful and mischievous demeanor. It is usually found in groups and often touch tails with other Pichu as a show of courage, creating a shower of sparks that can make them cry. It is inept at storing electricity, and may discharge if amused, startled, or subjected to shock. However, it cannot discharge without being shocked itself. Charging up is more easily done on days of dryness or thunderclouds. The crackling of static electricity generated by Pichu is audible. It can zap an adult human, but will surprise itself if it does. Pichu primarily lives in the forest, though it has also been depicted to thrive in urban areas.

Other Appearances
Pichu appears as a playable character in Super Smash Bros. Melee as a moveset clone of Pikachu. It was one of the five characters in Melee who did not return in its sequel, Super Smash Bros. Brawl.
