Kaio Ken

The Kaio Ken technique is a fictional, powered up state in the anime and manga series Dragonball Z. Only Son Goku has used it.

It was taught by Kaio-sama (KIng Kai). The technique is used to multiply Gokuo's full strength- be it x2, x3, or even x20. It was very helpful to Gokuo during the Saiya-jin saga and Freeza saga but wasn't used that much after Gokuo could turn Super Saiya-jin (Super Saiyan). though, it was used one rare time after the Cell Games in the Dead Tournament vs Pikkon- Gokuo was Super Saiya-jin and used Kaio-ken to power up even further and punched Pikkon through a moon. www.geocities.com/medbz2k3/dbzmovies
