Kaioken Technique

The Kaioken is a quite unique technique. Instead of consuming Ki, like the Super Saiyan transformations, the Kaioken consumes Health. All Kaioken levels create a red aura around the player, increasing with size for each transformation. Each level of Kaioken adds 10% damage (halved for non-Ki weapons), and 10% speed, but reducing defense by 5% and draining more and more health.

Trivia

 * In the show, this form puts a strain on the user's body depending on how high the multiplier is.
 * It was a technique created by King Kai, however Goku is the only being to be shown to use it successfully.
