界王拳 超サイヤ人ブルー界王拳 スーパーサイヤ人ブルー界王拳
A fighting technique in the [[Dragon Ball]] franchise. Invented by [[North Kaiou|King Kai]] alongside the [[Genki Dama]] and taught to [[Son Goku]]. It boosts the user's parameters for a short time, but becomes a burden on them as well. The body and aura turns a deep crimson color while in use.

In the [[Dragon Ball Super]] anime, Goku would combine the Kaiouken with his [[Super Saiyan Blue]] form to create "Super Saiyan Blue Kaio-ken":[https://dragonball.fandom.com/wiki/Super_Saiyan_Blue_Kaio-ken]. If the picture depicts Goku using this, tag with both Super Saiyan Blue and Kaiouken.
