Serpentine Style (蛇の流儀, Hebi no Ryūgi. VIZ: Orochimaru's Fighting Style) is a fighting technique employed by those who use snakes in various capacities, including to restrict, paralyze, attack, or even defend. Users often substitute attacks by replacing their bodies with snakes and are capable of summoning snakes through their clothes or transforming their bodies into snakes.
It is a term used to classify the snake-like fighting style of characters such as Orochimaru, Mitsuki, and others who employ similar techniques.
