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. It also causes the user's physical appearance to look different, with more red colored skin, and much lighter blue hair - almost appearing white.
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 ten time Kaio-ken 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 Kaioken. 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.

The technique makes its debut in Dragon Ball Xenoverse 2 where is was also named. Like the anime, the X10 multipiler 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.
- 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's under the X10 Super Saiyan Blue profile it's unclear whether Kaio-ken is referring to Super Saiyan Blue Kaio-ken or X10 Super Saiyan Blue Kaio-ken.
