Pikachu (USBIV)

Pikachu is a startable playable character in Ultra Smash Bros. IV and makes his fifth appearance in the Super Smash Bros. series. He was confirmed at the begining of the development and at the E3 demo alongside with the Original 8 for being a member of it, including Luigi, Captain Falcon, Ness and Jigglypuff. In the Pokémon series, Pikachu is an electric type Pokémon, evolved after Pichu it's second evolution before Raichu.
Pikachu has a semi-clone character in this game, known as Pichu, the first evolution form from him. Differently of Pichu, Pikachu is much stronger at his attacks and agility and bigger at height and range. But his mobility overall is lower than Pichu.
Pikachu's voiceclips are reused from Brawl and Melee voiced by Ikue Otani.
Pikachu ranks 28th place of the 103rd (A) putting him in the top tier classment, behind Palutena and after Lucina, making him a top tier character. This is a notable rise for Pikachu since he is a high tier character in Smash 4 and also as the most viable character in all Smash Bros. games, pairing with Fox.
