Skull Bash (Pikachu)

Skull Bash (ロケットずつき, Roketto Zutsuki, lit.: "Rocket Headbutt") is Pikachu's side attack in Super Smash Flash and side special move in Super Smash Flash 2. In the original game, Skull Bash does not need to charge and always propels Pikachu at the same distance, because of this, it is a very efficient move for recovering. In the reboot, Skull Bash was modified to match its Smash Bros. brethren, now Pikachu can charge up the attack. Pikachu will have electricity running through him when charging. Uncharged, the attack deals 12% with little knockback, while fully charged, Skull Bash deals 17% to the opponent with great knockback.

Trivia

 * Pikachu is unable to learn Skull Bash in the Pokémon games, except for Pokémon Red and Blue, where the move could be taught as a TM.
