Night Guy | Might Guy
The Night Guy is a forbidden taijutsu of the highest level and can only be performed after opening all Eight Gates
When Guy initiates the technique by saying "amass" (積, seki), he emits an enormous amount of red steam, the so-called "Steam of Blood" (血の蒸気, Chi no Jōki), and his chakra manifests into a red burning dragon around his body. Shouting "flow" (流, ryū), he then dashes forward at such an extreme speed that the space ahead of the user is distorted, making it impossible for the target to defend against it. Guy then deals an immensely powerful kick which carries such force that it is capable of obliterating the target's body, as well as creating a devastating shock wave linear to the kick. The damage itself was so great that even Madara Uchiha as the Ten-Tails' jinchūriki feared for his life.
