Like the variation of the technique utilizing Super Saiyan Blue, the user utilizes the Kaio-ken technique whilst in their Super Saiyan 4 form. Usage of this technique produces an equally similar double aura effect of its own, with the flame-like golden aura of the Super Saiyan 4 surrounded by the jagged and violent crimson aura of the Kaio-ken. When used by Gogeta, it results in his hair turning bright orange.
In the Dragon Ball Z Collectible Card Game, Super Saiyan 4 Goku can use Kaio-ken.
Xeno Gogeta as a Super Saiyan 4 can use the Kaio-ken technique in Super Dragon Ball Heroes.
- Unused voice lines in Xenoverse 2 indicate that Gogeta can use the Kaio-ken while in Super Saiyan 4.
