Demon Scissors (破砕蹴, Hasaishū^?, lit. "Cracking Kick") is a move that has existed since the first game of the Tekken series. It can be performed by all practitioners of Mishima Style Fighting Karate as well as Ogre and True Ogre.

During the animation of this move, the character does a forward somersault to hit the opponent with one leg—or, in Kazuya's case after Tekken 4, both legs—and lands on their back. Each leg that connects does 25 damage. However, if Kazuya connects with the first leg, the damage of the second reduces to 80% (17 damage) because the opponent will be falling, bringing the total damage to 42. On a grounded opponent, the damage is 25 even with Kazuya. In Tekken 2, the move deals 30 damage but is reduced by a third to 20 when hitting a grounded opponent.

Jin was able to perform Demon Scissors in Tekken 3 and Tekken Tag Tournament, and Devil Jin was able to perform Demon Scissors in Tekken 5. Both had Heihachi's variant, but since Tekken 4 and Dark Resurrection, Jin has a completely different move, and Devil Jin has another move similar in execution. 

In Tekken 8, Jin gains access to Demon Scissors in The Dark Awakens when he adopts the Mishima style once again. He uses Kazuya's variant.

Trivia

• In Tekken 3 and Tekken Tag Tournament, Heihachi would take 5 damage if he whiffed Demon Scissors. Starting with Tekken 4, this was changed so that the player would have to press D when Heihachi hits the ground or hold D during the animation, e.g. 4~3,D to take damage on whiff. However, there is no advantage in doing this, as the move retains all the properties of its non-self-damaging counterpart. In Tekken 4, holding D will hurt Heihachi even if the move connects.
• Ogre and True Ogre cannot perform Demon Scissors using the original u/f+4~3 command but must use one of the two alternative commands introduced in Tekken 2.
• The Demon Scissors tag throw can only be performed with Heihachi, Kazuya, Jin, Devil, or Angel as the off-screen character. The Ogres will perform a Hammer Heel on the downed opponent instead.
• In Tekken Tag Tournament, if the player knocks out the opponent with a Demon Scissors tag throw with Heihachi finishing, Heihachi will hurt himself as though he whiffed.
• Although the properties, input, and damage are all different, one of Jinpachi's moves purely resembles the Demon Scissors. This may hint the origin of the move and likely the family's fighting style itself.
