Kaioken x100

is a powerful technique used by Goku in the Dragon Ball series. It multiplies his strength, speed, and power by 100, but puts a tremendous strain on his body. Goku first uses this technique during his battle with Frieza on Namek, pushing himself to his limits in order to defeat the tyrant. The Kaioken x100 is one of Goku's most impressive and devastating techniques, but it also comes with great risks and can only be sustained for a short period of time.
