First, Android 13 says "Let's end it!" as he attacks the opponent with a barrage of brutal punches. To finish the attack, he fires a red energy sphere at the opponent, inflicting a high amount of damage.
In Dragon Ball Z: Super Android 13!, Android 13 uses this attack during his battle with Goku. After Goku recovers from a Full Power Energy Wave from Android 13, he throws a gigantic glacier rock at 13. The Android easily dodges the rock and retaliates by forcing Goku back into the icy water, where he uses the "Deadly Assault" rush, blasting himself and the Saiyan out of the water to continue their fight.
