This variation of the Kaio-ken boasts a double aura effect, placing a crimson Kaio-ken aura outside of a typical blue Super Saiyan Blue aura. The outer Kaio-ken aura manifests as violently fluctuating and jagged while the Super Saiyan Blue aura maintains a gentle, flame-like contour. In its initial appearance, it also causes the user's physical appearance to look different, with more red colored skin, and much lighter blue hair - almost appearing white. These effects were presumably due to Goku's body not being able to stand the technique, as when he later used it after managing to get the point where he could survive using Kaio-ken at x20, his X10 Super Saiyan Blue Kaio-ken looked identical to his normal Super Saiyan Blue Kaio-ken.
Goku takes on this form by first transforming from Super Saiyan Blue into Super Saiyan Blue Kaio-ken, and the proceeding to power up further while shouting times ten.
Goku uses this technique in an attempt to finish off Hit quickly, however Goku is only able to maintain Kaio-ken x10 as a Super Saiyan Blue for short periods of time because it puts a great deal of strain on his body. As such, after attempting to defeat Hit with a Kamehameha, the multiplier seemingly faded and his Kaio-ken dropped to a lower level for the rest of the fight.
The full ramifications of using this technique manifested several days later as Goku developed Delayed Onset Ki Disorder caused by the unaccustomed and strenuous activity while using Super Saiyan Blue Kaio-ken. Symptoms include a significant decrease in ki control and capacity with such instances as Goku's diminished accuracy using his Instant Transmission and blowing up his house on accident. He even admits openly that in such a condition Piccolo would be capable of defeating him. Fortunately, King Kai informs Goku that this new condition will pass in time. However, King Kai called the technique reckless and irresponsible and warned Goku to not be so reckless next time as it is possible for the condition to stay with a victim permanently, making them incapable of getting stronger.
By the point of the Tournament of Power, Goku's mastery over this state is such that the stress generated is considerably lesser, making it appear as a normal Kaio-ken Blue. He later uses this form again when he tries to push back the Universe 7's Spirit Bomb that was fired at Jiren, he later ups the multiplier by x20.
Video game appearances
The technique makes its debut in Dragon Ball Xenoverse 2 where is was also named. Like the anime, the X10 multiplier can only be activated on top of the regular Super Saiyan Blue Kaio-ken. When activated, it drains Goku's health at an alarming rate. Goku can also use this form in Heroes and Dokkan Battle (as his super attack while in Super Saiyan Blue Kaio-ken form is 10x God Kamehameha). The form is also set to appear in Dragon Ball FighterZ.
- Despite being the result of a Kaio-ken x10 and even Hit noting the multipliers being applied, the profile for the X10 Super Saiyan Blue Kaio-ken form states that Kaio-ken doubles the fighting abilities of the fighter. As it is under the X10 Super Saiyan Blue profile it is unclear whether Kaio-ken is referring to Super Saiyan Blue Kaio-ken or X10 Super Saiyan Blue Kaio-ken. It can be noted the profile says the same statement Goku makes upon going Super Saiyan Blue Kaio-ken initially against Hit, not X10 Super Saiyan Blue Kaio-ken.
- Goku has only used this full powered state against Hit due to the result of ki disorder. By the time of his fight against Jiren, he is in full control of it.
- In Dragon Ball Xenoverse 2, when in Super Saiyan Blue Kaio-ken x10, Goku consumes no stamina when performing Z-Vanish and while in this state, Goku does not recover stamina. When Goku's stamina is broken, Super Saiyan Blue Kaioken x10 will automatically end. However, the balance of Goku's health while in this state will plummet at a very alarming rate and enables the opponent to defeat him with one hit.
