He just doesn't need to use it anymore since of Super Saiyan.
And the Kaio-Ken Technique Drains His Energy while Super Saiyan is more natural so he prefers Super Saiyan and stops using Kaio-Ken
Because of kaio ken
Goku's primary teacher is Master Roshi, who trained him in martial arts and introduced him to the basics of fighting. Additionally, Goku learns from other martial arts masters throughout his journey, including King Kai, who helps him develop advanced techniques like the Spirit Bomb and the Kaio-ken. Each teacher plays a significant role in shaping Goku’s skills and character.
Superman. Easily. Nothing to debate. That's the answer. Don't ask why. He just would. Sorry dude but Goku would kill superman in 2 seconds, Goku's got the kamehameha, spirit bomb, and Kio-Ken. Superman's got what? little eye lasers lol.
It's a techinque That only King Kai knew until Goku came along. At first u should never go beyond Kaio-ken X2 but Goku denied that topic in his fight against Vegeta by using Kaio-Ken x3 and x4. He also used it in Cooler's Revenge and the Return of Cooler. Then he used the times 20 Kaio-ken which unleashes a Power too great to handle for some enimnes. Basily The Kaio-ken requires to concentrate your energy into 1 point and it uses a lot of power but not as much as it is becoming a Super Saiyan
Goku learned the Kaio-ken technique from King Kai during his training in the Other World after his death in the Saiyan Saga. King Kai taught him the technique to enhance his speed and power temporarily, enabling him to compete against formidable foes. Goku mastered it through rigorous training and practice, allowing him to utilize this powerful technique in battles against stronger opponents.
If you refer to goku it is kaio ken
It's a energy attack that goku learns from king Kai that uses other people's energy that he uses as a last resort to finish off powerful enemies it's more powerful if people give him their energy ------------------------------------------------------------------------------------------------------------- ANSWER: It is Son Goku's most powerful move in the original manga, in all Kiao-Ken/SSJ forms it grows even stronger. -------------------------------------------------------------------------------------------------------------
Because of kaio ken
Well, honey, in Super Smash Flash 2, Goku activates his Kaio-ken by pressing the special move button and the up button simultaneously. It's as simple as that, darling. Just a couple of button taps and Goku is ready to kick some butt with that power boost.
Cuase he is stupid and doesnt know any better (Second answer) Actually, think. Super Saiyan requires a saiyan to push themselves really really hard. Which means it takes up a large amount of energy, while Goku still has to fight and being at such a high power level takes up energy as well. Now imagine if Goku is at Super Saiyan 4. Goku is at his peak. Then imagine Goku using Kaio-Ken in that form. Yes,his power level would be impossibly high(well practically everybody in the dbz universe is like God), much higher than it is at Super Saiyan 4, but Goku would get tired much faster. Then he loses energy.
No only Goku and King Kai know Kaio Ken.
press down and "p" at the same time and hold
