Dr. Mario (SSB4)/Neutral attack
From SmashWiki, the Super Smash Bros. wiki
Dr. Mario's neutral attack is a series of two punches and a kick that each start rapidly and do minor damage. It comes out quite fast and can stop approaches, although the different angle on the first hit prevents the attack from locking, unlike Mario's jab, hindering its utility.
