Ruthless Blow (非情の一撃) is an attack used by Frieza.
The attack starts off with Frieza saying "Out of my way!", he charges towards the opponent at high speed, then he uses Rapid Movement (disappearing from the opponent's line of sight). The opponent suddenly feels a stabbing pain, and discovers to their shock and horror that Frieza has thrust his hand/palm into their back. Frieza ends the attack by pulling his hand out of the opponent's back and letting them fall helplessly to the ground.
Frieza attempts to use this technique to finish off Vegeta on Namek, but is stopped when Goku arrives. On Earth, Frieza uses the Ruthless Blow to execute one of King Cold's soldiers for cowardice, as the soldier shows signs of fear to Future Trunks after his comrades are killed. In Hell, Frieza attempts the technique to finish his Vengeance attack and kill Goku, but Goku manages to barely dodge it.
Appearances in games
The version attempted in Hell appears in the Dragon Ball Z Collectible Card Game, on the card "Black Frieza's Left Chop".
- Frieza using the Ruthless Blow technique to execute one of his soldiers for cowardice is somewhat ironic, as killing someone while their back is turned is generally considered a cowardly action.
- In the Dragon Ball Collectible Card Game, Rutheless Blow is the name of the strong kick attack to the neck used by Zarbon to kill one of the elder Namekians in Moori's village.
