Leg Bazooka is a move used by Bruce Irvin since Tekken 2, as well as Ogre and True Ogre since Tekken 3. In the PlayStation version of Tekken 2, and for the Ogres in Tekken 3 and Tekken Tag Tournament, it is called Foot Bazooka. In Tekken Tag Tournament 2, True Ogre would forget this attack though Ogre would keep his, but it would be renamed to Leg Bazooka.
Bruce also has a variation of this move called the Leg Bazooka Feint.
