Pikachu

Pikachu is one of the types of Pokémon species. They first debuted in the first generation of Pokémon games, and have since been considered the mascot of the sereis. Without a doubt they are the most popular of the Pokémon species, possibly for being the first Pokémon that Ash obtains from the television series.

Because of Pikachu's immense popularity, they have appeared as a playabe character in every Super Smash Bros. video game, which currently consists of Super Smash Bros., Super Smash Bros. Melee, and Super Smash Bros. Brawl. Pikachu was the cover mascot for Pokémon Yellow, where he was your starter Pokémon (you couldn't choose).

Their first anime appearance was in "Pokémon, I Choose You!".

Characteristics
A Pikachu is a small, yellow rodent with electric abilities. Pikachu have short yellow hair with black stripes on its back, black-pointed ears, and a curious tail resembling a lightning bolt in the case of male Pikachu, and a more rounded heart-like tail in the case of female Pikachu. Thanks to its big ears, Pikachu have good hearing capacities, as well.

Pikachu and the rest of its evolution family, Pichu and Raichu, are the only Pokémon able to learn Volt Tackle. In specific cases, Pikachu are shown to be able to use the moves Surf and Fly.

Super Smash Bros. series
In Super Smash Bros., several of Nintendo's Super Stars fight against each other. And since Pikachu is the mascot of the popular Pokémon series and Pokémon is Nintendo, Pikachu was one of the original 8 starter characters. There are also two sequels, Super Smash Bros. Melee, and Super Smash Bros. Brawl in which Pikachu is playable in all of them. In this series, Pikachu can use Thunder, Quick Attack, Thunder Jolt, and Skull Bash (Skull Bash was introduced in Melee). In Super Smash Bros. Brawl, Pikachu can use a move called Volt Tackle as his "Final Smash". Pikachu can use this move after he breaks a Smash Ball. Pikachu will turn into a giant electric ball that you can control, but when Pikachu controls the ball you have to be careful because the ball goes really fast!
