Fist of the World Lord Turtle Destruction Wave
|Debut||"Saiyan Sized Secret"|
Kaio-ken Kamehameha (界王拳・かめはめ波; lit. "World King's Fist Turtle Destructive Wave") is a combination of the Kaio-ken technique and the Kamehameha used by Goku. Goku transforms into his Kaio-ken form and uses the Kamehameha, inflicting extreme damage depending on what Kaio-ken level he is using for the attack. The only known Kaio-ken levels he used for the attack are Kaio-ken x3, Kaio-ken x4 and Kaio-ken x20.
This technique looks very similar to a standard Kamehameha Wave. The only noticeable different is that the wave is larger and much more powerful. As the Kaio-ken multiplier increases, the wave gets larger.
Main article: Vegeta Saga
After being battered around by Goku's Kaio-ken x3 attack, Vegeta ended up losing his temper. The Saiyan prince then flew up in the air and launched his Galick Gun, intent on destroying Goku along with the Earth. Out of fear of letting the blast hit the Earth, Goku used the Kaio-Ken x3 Kamehameha to repel the Galick Gun. Seeing how both attacks were evenly matched, Goku used Kaioken x4, surging through the Galick Gun and blasting Vegeta into the sky. However, his body was left exhausted and weakened from having used so much power.
Main article: Frieza Saga
During the fight with Frieza, Goku gets thrown underwater by the tyrant, who attempts to drown him. However, after seeing a vision of his friends and family being murdered and earth destroyed, Goku regains courage and raises his Kaio-ken to x20, the highest Kaio-ken level. Goku then beats around Frieza and fires a gigantic Kaio-ken Kamehameha at the tyrant, damaging him slightly. The blast was named x20 Kaioken Kamehameha in Dragon Ball Z: Budokai Tenkaichi 3.

Main article: Dragon Ball Z: Cooler's Revenge
Seeing as he was no match for Cooler in his final form, Goku used the Kaio-ken x20 Kamehameha against the tyrant. However, unlike his brother, Frieza, who was damaged by the attack, Cooler simply surged through the blast and attacked the surprised Goku.
