Kaio-ken Attack (界王拳アタック Kaiō-Ken Atakku, lit. "Worlds' King's Fist Attack") is a Rush Attack used by Goku while using the Kaio-ken.


Goku kicks Vegeta in the back

Goku powers up to Kaio-ken x3 as he charges at the opponent and roundhouse kicks them up into the air. Then, he flies up in the air and punches the opponent away. Next, he flies up over the opponent and down behind to double kick them further up into the air. Finally, Goku flies up into the air around the opponent and hook kicks them down into the ground, inflicting a huge amount of damage.


Goku uses this attack during his first battle against Vegeta. After being dominated by Vegeta's increased speed and power even with his Kaio-ken x2, Goku decides to use his Kaio-ken x3. Goku charges up and his power soon surpasses Vegeta's, much to the Saiyan prince's shock. Activating his Kaio-ken x3, Goku rushes at Vegeta and attacks him with the Kaio-ken Attack, knocking him many meters away into a mountain.

Video Game Appearances

Goku uses Kaio-ken Attack in Raging Blast 2

Kaio-ken Attack was named in the Budokai Tenkaichi series, where it is one of Goku (Early)'s Blast 2. In Dragon Ball Z: Budokai Tenkaichi and Budokai Tenkaichi 2, the name was given to Goku's other Kaio-ken rush attack, Kaio-ken Finish; this was later fixed in Dragon Ball Z: Budokai Tenkaichi 3 and Dragon Ball Z: Tenkaichi Tag Team. The Raging Blast series and Dragon Ball Z For Kinect feature the Kaio-ken Attack and Kaio-ken Finish as separate attacks. It is one of Goku's Special Attacks in Dragon Ball Z: Battle of Z.

In Dragon Ball Z: Supersonic Warriors 2, the rush appears as an Ultimate Attack finished by a Kaio-ken Kamehameha for Goku in his base form.

In Dragon Ball Xenoverse 2, it appears under the name Kaioken Assault as one of Goku's Super Skills which the Future Warrior can obtain by purchasing it from the Skill Shop in Conton City.


  • Like with the Kaioken Kamehameha and its x4 and x20 multipliers, the Kaioken Attack can be used even when the Saiyan Future Warrior is transformed in any Super Saiyan form, despite Goku stating in Dragon Ball Super that other than the Super Saiyan Blue Kaio-ken, using the Kaio-ken and Super Saiyan forms together would kill the user due to the form making the precise ki control necessary to use the Kaioken safely impossible making it fatal to the user (unless one is already dead as Goku was able to use it while deceased when he fought Pikkon in Dragon Ball Z). The Warrior's ability to do so is left unexplained though presumably it is either an oversight or the developers ignored it for gameplay reasons (similar to how the Future Warrior is able to use the Spirit Bomb and Super Saiyan Bomb even as a Super Saiyan 2 and Super Saiyan 3). It should however be noted that the Warrior cannot actually use the Super Saiyan and Kaioken Awoken Skills together as there is only a single slot for Awoken Skills and can only use the Kaioken and Super Saiyan forms together when using Kaioken-based Super Skills or Ultimate Skills and they can use the Kaioken with other Awoken Skills such as Turn Golden, Potential Unleashed, and Kaioken itself.
