Bone Breaker, called Falling Leaves (落葉/Raku You) in Japan, is a move used by Paul Phoenix since the first game. Paul performs a fast sweep followed by a Flash Elbow.
Description[]
From Tekken 2 onwards, this move can also be chained after a Hammer Punch, where the combo is called Hang Over. The Bone Breaker also forms the fifth and sixth hits of Paul's second 10 Hit Combo, however it doesn't cause the opponent to fall.
From Tekken Tag Tournament onwards, the sweep will only cause knockdown on a clean hit or a counter hit. Also since Tekken Tag Tournament, if the sweep is blocked Paul will stagger and be unable to follow up with the Flash Elbow, leaving Paul at a 34-frame disadvantage.
In Tekken 4, the second hit now received a Clean hit property that depends on the timing of the second hit's input. The string was also extended to the Demolition Man.
Tekken 7 would remove both Clean hit properties and the timing restriction for Bone Breaker's last hit and its transition to Demolition Man.
