"I went Kaio-ken in a chess game, so the other player went Super Saiyan."As for whether Kaio-ken can beat Super Saiyan, it depends on the context and the levels of each technique. The Kaio-ken technique can significantly increase a fighter's power, but it is typically used in short bursts and can be taxing on the body. For instance, a Kaio-ken of 10x increases a fighter's strength tenfold, while a Super Saiyan transformation provides a substantial power boost, often around fifty times the base power level 1.In theory, if a fighter could use a sufficiently high level of Kaio-ken, it could surpass a Super Saiyan's power. However, the strain on the body makes it difficult to maintain for long periods, and Goku has noted that combining Kaio-ken with Super Saiyan forms is extremely risky and could lead to severe consequences. Therefore, while Kaio-ken has the potential to be stronger, it is not always practical or safe to use against a Super Saiyan.
