Has it ever been explained why goku never

[shonenhikada]

Combined the Kai-o-ken technique with his now mastered Super Saiyan god form. Surely going 20x and so forth would help him in a fight.

Also has it ever been explained why goku has never used kai-o-ken with Super Saiyan at all ?

[Lord Beerus]

Because his body would most likely implode if he tried this. I mean, even having a deceased body, which much tougher than a mortal body, and he could only maintain the "Super Kaioken" form a few seconds before it disappeared. Goku tries the same trick again with his regular, mortal body and he implodes.

Other World Tournament is anime filler. The new movies are manga canon. Therefore we don't know if Goku can actually use the Kaioken while Super Saiyan (canonically.)

Seeing as that the SSJ kaioken wasn't written by Toriyama to begin with, I feel as if Toriyama wants to have a maximum power-up of 1 at a time. So, anyone in a transformed state couldn't use a technique that makes them stronger (if anyone can name an instance that would contradict this hypothesis it would be much appreciated for you to mention it). And as such, we can only speculate as to what would happen if that were to happen. I personally think that their bodies just couldn't take it. I imagine it as two internal forces crashing into each other and causing a very bad reaction.

The thing about it is. The super saiyan god form raised Goku's base power to a new level. So technically Goku is just really really REALLY STRONG IN BASE (6) NOW. So I'm just curious why he can't combine the technique of kai-o-ken to fight strong foes.

Doesn't make sense for me.

Besides it is an in-universe topic. And Goku using Kaio-Ken has nothing to do with new movies.

Toriyama's essentially using the Jump Special, BoG and RoF as his means of continuing the manga. They're his stories, not so much TOEI's. The guy essentially retired as a mangaka at this point. Even when he does one-shots, most of the time he still teamed up with Katsura rather than draw it himself. The new movies are the same concept, except he lets TOEI animate them rather than get somebody to draw DB manga for him.

In other words, it's not just a matter of being paid to do design concepts for TOEI like in the old anime filler, so much as he's drafting the story and the designs.


As for the original question at hand, Kaioken, SSJ and SSJ God are all variants of the same thing with different strengths and weaknesses. Therefore, Goku has no reason to combine kaioken and SSJ God. To do so would still get him the exact same result as the combination of SSJ God and SSJ does, only it would work in very short bursts like Kaioken does. Very impractical.

Let's say he could use Kaioken while Super Saiyan God. Kaioken damages his body while using up his ki. Combine that with being Super Saiyan would only do further harm to Goku and drain his power even faster.

If I recall, Goku has to do something with every muscle or cell in his body to do the Kaio-ken. Then it is extremely stressful on his body, hence touching him makes him yell in pain after Vegeta leaves Earth. On the other hand, becoming a Super Saiyan multiples his power exponentially (more than a 20x Kaio-ken does) and he doesn't have the bodily stress from it. That's what I recall reading on the DB Wiki.....

TL;DR Kaio-ken is too stressful. SSJ is more powerful and hardly requires any physical stress, so it's useless.

I may agree with BoG and RoF, while both of them don't actually continue the manga, but Toriyama doesn't use Jump Special, only the basic premise of a movie was written by Toriyama, but it was changed by both Naho Ooishi and Toei staff, and they are credited as creators of script, not Toriyama.

[Dyno]

Naho's manga has nothing to do with Toei's staff. Toei works with the anime/animated version, author works with the manga.
