Slaughter High Kick (六腑閃烈脚, Roppu Senretsukyaku^?, lit. "Six Entrails Flash Fury Leg") is a move used by Kazuya Mishima since Tekken 5. It is an extension of his Entrails Smash that follows up with his Roundhouse.

In Tekken 6: Bloodline Rebellion, the second hit was reanimated into a back-spin roundhouse kick and, in Tekken 7, triggers a Screw. Starting with Tekken 7: Fated Retribution the second hit can be done by itself as the Flash Tornado, where it also gains homing properties. Prior to Tekken 8, if Kazuya is in Devil Transformation, he is unable to perform this attack.

In Street Fighter X Tekken, Slaughter High Kick is single special move input and no longer grants a knockdown on hit.
