Colossal Slash (ハイパワースラッシュ,Haipawāsurasshu, lit. High-Power Slash) is a two-handed variation of Power Impact used by Jiren.
Jiren gathers Ki in both hands and combines them into a single powerful sphere and lifts it above his head before launching it at the opponent.
Jiren first uses this technique against Android 17 who blocks the attack using his Final Barrier and then destroys the attack by using self destruction. Jiren again uses this technique against Ultra InstinctGoku, who repels the attack with an Energy Wave.
