Resonating Echo Drill

 * User: Dosu Kinuta
 * Debut (Anime): Naruto Episode 31

This jutsu can be used as a blanket term for the majority of Dosu's jutsu. The Melody Arm, a porous metal device located on his arm, is used to amplify the sound waves from arm movements to attack his opponent. By generating enough sound, Dosu can use his chakra to redirect the waves in midair to his intended target. By damaging the victim's inner ear, the victim is rendered off-balance and nauseous. In the first instance of this, Rock Lee is rendered physically sick by the attack.

As seen in Dosu's fight with Choji Akimichi, the sound drill can also be directed through water weight to similar effect. Therefore the greater fat index an opponent has, the more they are affected by this; Choji, using his Multi-Size Technique at the time, was instantly defeated.
