Pikachu is the most recognizable "Pokemon" character, according to GameFAQs.com. The yellow mouse-like creature has a tail shaped like a lightning bolt. Pikachu is the primary mascot for the animated "Pokemon" television series.
Pikachu is both the name of this character and the name of the species it belongs to. Pikachu fights other "Pokemon" characters by projecting electricity from its body. When Pikachu comes across something new, it blasts it with a jolt of electricity. Pikachu keeps its tail raised to monitor its surroundings and can transform itself into a Raichu, a more evolved version of a Pikachu, if it is exposed to a Thunderstone.
