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
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
Because he is too awesome!!! :D.Seriously now he is stronger because he managed to transform to Ascended Super Saiyan aka Super Saiyan 2 while goku couldn't achieve that at that time!Of course later in the anime goku becomes once again stronger than everyone else. Gohan isn't stronger anymore because even though he became ultimate and beat the crap out of super buu goku managed to go ssj4 while gohan lost some of his powers in gt because he stopped training.
Ken. Ryan Ken Potter.
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. -------------------------------------------------------------------------------------------------------------

While playing Goku, hold down Down+Special, so Goku yells, "Just getting started!" Blue sparks should fly out of Goku until they touch an enemy, so Goku can accomplish the Kaio-ken form. As long as Goku is in Kaio-ken, his damage % constantly increases until you do Down+Special again to transform back into regular Goku, die, or wait too long before you hit someone, since Kaio-ken Goku automatically reverts back to normal if he doesn't continue to hit someone. Therefore, Kaio-ken Goku can't charge his Kamehameha much, so you should focus on using his physical attacks, which gain more power and knockback. The most significant change in Kaio-ken form is Goku's Side-Special Kaio-ken Attack, which unleashes a series of hits to devastate the foe if the foe gets caught in this combo.
No only Goku and King Kai know Kaio Ken.
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.
press down and "p" at the same time and hold
goku in that form has the power of 400,000,000,000,000,000,000,000 suns optimus prime has the power of 500,000,000,000,000,000,000,000 suns optimus prime wins

Go to the edit skill list on dragonball z budokia 2 and highlight goku and give him false courage,kai oh ken, and supersaiyan it might take some practice.
