Demon Basara is a move used by Heihachi Mishima since Tekken 7 Season 2 as his second Rage Drive. It was given an official name in Tekken 8 and the final command was changed.
Description[]
Heihachi performs the first two attacks of Demon Lair/Demon Massacre - a left jab to the face then a spinning midsection backfist with the right - before ending with a headbutt. In Tekken 7 this would knock down into a Bound but in Tekken 8 the opponent is left in a crouching state. The move was a natural combo on Counter Hit in Tekken 7 but in Tekken 8 only the latter two hits are natural.
In Tekken 8, pressing d after the second hit will cause Heihachi to enter Wind God's Kamae without completing the string.
If this attack is performed when Warrior Instinct is active it becomes the Ultimate Demon Basara.
