Skull Bash

Skull Bash is a move that both Pichu and Pikachu know in Super Smash Bros. Melee. It is executed by pressing forward+B. The player could hold down on the B button to charge the attack. Then, the player could let go, releasing a very strong attack.

Trivia

 * Despite the fact that Pikachu can indeed use Skull Bash in Super Smash Bros. Melee, he has never been seen executing it in any of the Pokémon games.
 * This attack is very similar to the Green Missile. Even one of Luigi's trophies states that Luigi's Green Missile move is similar to the Skull Bash.
