Kaioken

This is a technique which its user can multiply their power level. This can multiply power and speed. During the Saiyan Saga, King Kai teaches Goku this technique. If you use this technique recklessly, it can put a strain on your body. Blue Kaioken is when Goku added the Kaioken on top of Super Saiyan Blue. Goku originally used the Kaioken against Vegeta. Goku originally planned to use Blue Kaioken against Beerus, but then he used it against Hit.

From the anime Dragonball Z, Kaioken is the fighting technique taught to Goku (the only one to master this technique) by King Kai. Though King Kai created this technique, he admits that not even he is able to fully master it.

The technique is very similar to going super saiyan, although the power increase is not as high, it is very effective before Goku first transforms. Goku discontinues using the Kaioken attack after his fight with Pikkon, opting instead to attain high super saiyan levels.

The technique only last a few seconds according to Goku so you "have to get the job done quickly". It momentarily greatly increases your speed, strength and abilities, allowing you to achieve a power level unobtainable without the use of this technique.

Through experience and training, the user can achieve multiple 'levels' of Kaioken, increasing the users abilities even further. However, according to King Kai, if you go up too far, your body will not able to handle it, and all the mass in your body will be replaced by energy, thereby making it explode. Goku is able to withstand a 4x Kaioken while fighting Vegeta, (putting his fighting power well over 23,000) in order to counter his Galick Gun attack. However, after this feat his body is thrashed and has no other way of attacking other than using the spirit bomb, another technique exclusive to Goku and King Kai. Cell states that he could use this technique if he wanted to, however.

A Power Multiplier move in Dragon Ball Z that pretty makes you from trash to beast, it can be times up to 20 but it depletes your stamina and gives a strain to your body so you have to be cautious using it.

Hi guys! Yamcha here again and we're gonna talk about this attack! The Kaioken X4 Kamehameha is an attack Goku used in the Saiyan Saga to damage Vegeta by a lot. This attack is used to beat enemies with a lot more strength. The only time Goku used this is when he met against Vegeta. This attack was used to clash with Vegeta's fully charged and fully powered Galick-Gun. Vegeta put all of his power into the Galick-Gun. Goku however goes Kaioken X3 and charges up a Kamehameha fast enough and has enouh time to put power into the attack. He fired it and clashed against Vegeta's Galick-Gun. Vegeta at that rate was winning and was about to kill Goku, but Goku powered up his Kaioken to X4! This made him stronger and he almost killed Vegeta. He spared Vegeta after that and the rivalry started.
