History:

North Kaio-Sama is the God of the Northern Universe, and although he cannot even perform some of his own techniques, he is a very skilled martial arts master. Goku Travels to his planet, which is at the end of Snake-Way, in order to train with him for his battle against the Saiya-jins.

Training Techniques:

Kaio Laugh

Kaio Laugh

The very first thing North Kaio had Goku do was try to make him laugh. The point of this technique is unknown, but Goku, after a few attempts, made North Kaio-Sama crack.

Chase Bubbles

Chase Bubbles

The second training method used by North Kaio was a game with his pet monkey Bubbles. Goku had to try to catch this incredibly fast pet in 10x gravity. Goku had a lot of trouble catching the monkey, but used his mind combined with speed to finally do it. The point of this exercise is to build the user's speed.

Bash Gregory

Next, Goku was given a huge Mallet and was told to hit North Kaio's other pet, Gregory, with it. Gregory was even faster than Bubbles, and Goku had a lot of trouble with this also, but eventually got it. The point of this exercise is to build strength.

Fighting Techniques:

Genki Dama:

The Genki Dama was first introduced to us during the Saiya-jin saga. It was taught to Goku by North Kaio, and in order to charge it the user has to be in total harmony with nature. First, you must raise your hands in the air then call upon all living things to donate energy to you. Once it has reached the desireable strength, you can then compact it into a ball and throw it. It usually takes a while to charge up a very powerful one.

Kaio-Ken:

This power-up is perhaps the most famous technique North Kaio taught Goku. The power the Kaio-ken can give you depends on your bodies durability. Each new level over powerup is your base level times a multiple, so a Kaio-Ken x2 would be double your power. Goku successfully powered up to Kaio-Ken x20 to fight Furiza. The user's Aura turns red.

Ryu-Ken (Dragon Fist):

The DragonFist technique was taught to Goku during the afterlife. It is personally one of my favorites in that a Golden Dragon actually appears while performing this technique. The user must shout "Ryu-ken" and punch forward, creating a Golden Dragon that will punch through the victim, then surround it and explode.
