Pikachu

Pikachu appeared in 1996 video game called Pokémon Red & Green. Pikachu is a Mouse Pokémon. Pikachu naturally stores up electricity in its body, and it needs to discharge that energy on a regular basis to maintain good health. To take advantage of this, some have suggested creating a Pikachu-fueled power plant.

Pikachu are small, chubby, and incredibly cute mouse-like Pokémon. They are almost completely covered by yellow fur. They have 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. They turn yellow and spark with electricity when its about to use an Electric attack, such as Thunderbolt. It has also been known to generate small surges of electrical energy in anger or for protection, like in the anime.

A female Pikachu looks almost exactly the same as a male, with the exception of her tail, which is rounded at the end and has an inward dent, giving it the appearance of a heart. However, in earlier anime episodes, and in the games prior to Generation IV, female and male Pikachu look identical.

When several of these Pokémon gather, their electricity can cause lightning storms.

In SM091, according to Pikarla, the fur from Pikachu in the Kanto region sparkles in sunlight, while the Pikachu from Alola fur is silky smooth and shines in sunlight.
