Captain Ginyu uses this technique after learning that Goku's power level is much higher than his own, with Goku's power being 180,000. Luckily for Ginyu, he has his Body Change technique, to swap bodies with someone stronger and more powerful. To make sure Goku does not interfere with his plans once he swaps bodies, Ginyu uses the Self-Harm technique in order to handicap his old body, punching a hole into the right side of his chest.
Video Game Appearances
Self-Harm is depicted in a cutscene with Goku and Captain Ginyu in Dragon Ball Z: Budokai. Ginyu also uses Self-Harm before using the Body Change in the Budokai series. The technique was named in the Budokai Tenkaichi series, where it decreases Captain Ginyu's health when used, but either puts him in MAX power or boosts his other stats. It also appears in Dragon Ball Z: Burst Limit under the name Holstein Shock.
Self-Harm appears in Dragon Ball Xenoverse again under the name Holstein Shock. As in all other portrayals, it removes a good chunk out of the user's health, but has no secondary beneficial effects. It is also a custom skill for the Future Warrior (who can learn to use the Body Change technique from Ginyu). Its primary function in the game is the same as in the main series: to weaken the user's body in preparation for a Body Change. Its secondary use is activating Z-Souls that require the user to be in a critical state of health, lose a certain level of health, or receive a certain amount of damage.
In Dragon Ball Xenoverse 2, Holstein Shock returns as one of Captain Ginyu's Super Skills. It can be obtained by the Future Warrior as a reward in Parallel Quest 15: "Gotta Find That Dragon Ball!" while the Body Change can be learned from training with Captain Ginyu in Conton City. It functions the same way it did in Xenoverse.
In Dragon Ball FighterZ, Self Harm appears as part of Ginyu's Body Change. If the player holds down the button to Body Chnage, Self Harm will be much more effectiv, taking a good portion of Ginyu's health.
- Its name in the Xenoverse series and Burst Limit, Holstein Shock is likely a reference to (known simply as Holsteins in the US) a breed of diary cow that are known as the highest producing dairy animals, which fits with the Ginyu Force diary-based naming puns. Ginyu himself has a history of the names of his techniques being diary related such as Milky Cannon.
