Behind You! (後ろ!) is a physical technique used by Raditz.
Raditz faces away from his opponent, then as they charge towards him to attack, he kicks out backwards and sends his opponent rolling away.
Raditz uses this attack during his battle against Goku and Piccolo. After dodging Goku and Piccolo's first flurry of attacks, Raditz uses "Behind You!" as a counter-attack, catching them off guard and knocking them away. He then uses the momentum to launch the Double Sunday attack.
Appearances in games
"Behind You!" was named in Dragon Ball: Raging Blast as one of Raditz's Super Attacks, a counterattack where the opponent needs to punch the user while the attack is activated. It is a bonus super attack unlocked in the Tournament Mode. It returned in Dragon Ball: Raging Blast 2 and in Dragon Ball Z: Ultimate Tenkaichi. In Dragon Ball Z: Burst Limit, one of Raditz's drama pieces consists of him shouting the attack's name, but it is not shown if he kicks or punches the opponent.
