Pikachu (SSB)/Floor attack (back)
From SmashWiki, the Super Smash Bros. wiki
Pikachu whirls around while using its two feet to attack surrounding opponents, hitting the back first, then the front and gets up. The back has short range and does 6% damage and very low knockback. While the move has a fast start-up and can be used as a get away from me attack, it has rather noticeable ending lag which can cause Pikachu to get punished easily if one shields. Like other floor attacks, this attack has very little use in competitive play.
