Goku: "Yeah, but I need to beat Granola! I have to go EVEN FURTHER BEYOND! KAIOKEN TIMES ONE MILLION!!!"

King Kai: "You fool! The strain will kill you!"

Goku: *dies from kaioken strain*

King Kai: "You just hakaioken'd yourself"

Vegeta’s version of Kaioken derived grime training with Beerus. This technique not only boosts his power but cloaks him in hakai energy making hitting him almost impossible.

Vegeta: Now Granolah, prepare for your end, HAKAIOKEN.

Hakaioken

When you pump up the kaioken multiplier so much that it physically destroys you. Often happens when you try to go beyond Kaioken x100

Goku: "It won't be enough to beat Granolah! I have to go EVEN FURTHER BEYOND! KAIOKEN TIMES ONE MILLION!!!"

King Kai: You just Hakaioken'd yourself
