The technique was named All-Out in Dragon Ball Z: Budokai Tenkaichi 3, where it is one of Piccolo (Early)'s Blast 1. Using this technique requires 3 blast stocks. It raises all of Piccolo's attributes slightly, along with giving him MAX Power.
All-Out is re-introduced in the Raging Blast games as one of Piccolo and Yamcha's Super Attacks. The technique does not give the user MAX Power as in Budokai Tenkaichi 3, but it raises his attack power, defense power, ki recharge speed, and Super Attack power dramatically, as well as drain his energy bar. The technique's effects end once the energy bar is fully drained.
