Why couldn't Goku combine Kaioken with SSJ?

[Floydical]

I read up on the technique on the wiki, at least the manga parts, and there doesn't seem to be a reason given as to why he can't combine the techniques. Knowing the Piccon fight was non cannon, there is no evidence in the manga proving they can be combined. The only explanation given is that SSJ simply overpowers the Kaioken, but this doesn't explain why it can't logically be combined.

So was there ever an explanation given or some evidence explaining why Goku couldn't combine Kaioken with SSJ? Is the SSJ form simply so powerful that he can't maintain such a powerup for that reason? Would a SSJ Kaioken kill him?

Thoughts on the matter?

Goku too OP might destroy reality.

Well, considering how stressful Kaioken was on his body by itself, trying to combine it with something
like SSJ I would imagine would be extremely painful. He'd probably struggle to move and burn out extremely
rapidly at the same time.

It takes a large toll on his body to use kai o ken and super saiyan does too (not as much though) combining them could injury him more then its worth

Also this is the guy who said goten and trunks don't have tails because he forgot about them (giving a bs excuse that its a recessive trait, if it was a recessive trait gohan wouldn't have had a tail) and also changed hercule, mr satans,mark, whatever the most recent name is name a hundred times.

It has been a long time since I've seen the show, but I believe Goku was using Kaioken attack while SSJ during the Cell Games. Piccolo or Gohan mentioned it.

This is the plot at work

 

[SSU]

Goku mastered SSJ and it isn't hard for him to use. Kiao ken is too dangerous to use. But if he could lower the risk then I can't see any reason for him to not use it.

The wiki page does not paint an image of such a scenario, only that it was used in a filler [non canon] episode.

Seemed like this to me.

Exactly my point. He doesn't strain to use SSJ. He should easily have been able to train up Kiaoken usage while in SSJ just like he did in normal mode.

He has used it in non canonical scenarios.

The reason why he probably didn't use it in canon is because of his fight lengths. All the opponents Goku went against after SSJ and above either did not require it or were too strong to get one shot.

See Kaiokain increases speed, strength , power for a short time. Then it becomes too taxing. The move is ideal if you think you can one shot the opponent.

Against Freiza when he reached SSJ he was vastly
superior and hence did not need to strain his body.

Cell was far superior to Goku and his main aim was to let Gohan watch his fight. This could be done by prolonging the fight. Kaiokain was clearly not the best move here

Buu was much more superior as well. Further his regeneration was much much advanced than Cell. One overpowered Kaiokain attack would not have done him any good here either.

He used the attack against Pikkon because one shotting him would work.

 

[Neji Hyūga2]

Goku has used Kaioken on top of Super Saiyan form before, he just doesn't do it often.

I assume since using it strains the body and I guess he rather not do that and just power-up instead with SSJ.

 

[Game Of Deities]

he did it in a filler arc against pikkon

 

[Floydical]

As I said in the OP, the Pikkon fight was not canon so it doesn't count. Obviously the anime crew thought of the same possibility and added it in.

I don't think Cell and Buu being stronger is enough reason. If I remember correctly, Goku felt he could match Cell's strength after training in the Hyperbolic time chamber, but knew he couldn't win. If he was capable of using a Kaioken/SSJ combination, that would have been the time.

I did come up with one idea. That being, using Kaioken and SSJ is comparable to the looking right and left dilemma in the Naruto universe. Naruto was able to conquer it by having a clone do the required nature manipulation that was otherwise impossible for him to do.

Perhaps these 2 techniques fall into the same category, and it would be impossible for Goku to actually combine them.
