Regarding Cell and Kaioken...

[Almighty Majin]

So one thing that has bothered me in the series is the fact that Cell should have been able to use the Kaioken technique, but he never did. I'm assuming that Toriyama simply forgot, but what would be the in-universe reason for Cell not using Kaioken?

Also how would the series have gone if he did use the Kaioken (like beyond the Cell Games)?

There is none. Cell should have known, there's really no explanation beyond Toriyama's forgetfulness.

Also how would the series have gone if he did use the Kaioken (like beyond the Cell Games)?

If who did? Goku? Well, the Boo Arc would have been a lot shorter.

No I mean if Cell had used the Kaioken since if he did, he would have dealt with Gohan no problem. I was wondering how everything would go after that.

Cell Destroys Earth, chills in space doing whatever he wants. He has Saiyan DNA, so he may go looking for a fight. If he ever ran into Beerus, he's be killed. Barring that, he'd probably just be an uber-powerful destructive force.

What if Cell unlocks SSBlue and Frieza's golden form, and then combines the two and stacks Kaioken on top? Surely then he could take Beerus.

How do we know he wasnt? Remember on Namek noone thought Goku had used the Kaio-Ken when he had been the entire battle.

[Jinzoningen MULE]

How do we know he wasn't? Remember on Namek no one thought Goku had used the Kaio-Ken when he had been the entire battle.

Yeah, that was to build tension, pointing out to us how amazing Freeza actually was. Also, at least in the manga, it was revealed almost immediately after they started fighting seriously. We would know if he were using Kaio-ken.

Not if noone knew it. We only found out because King Kai knew. Youre 100% right but I'm just attempting an entirely in universe explanation.

[Attitudefan]

An in-universe explanation could be that, yes Cell has Goku's DNA, but it doesn't mean he has the technique mastered. Goku's cell's are only some fraction of Cell's make-up. Perhaps Cell cannot use the Kaioken because it could destroy him, much like King Kai warned could happen to Goku.

Cell dosen't need to worry about his body getting wreaked, he can regenerate in a min max..
Which always makes me wonder why piccolo wasn't give the kaioken, and makes me praise the sun buu didn't see and master it

[Attitudefan]

Would Cell be weaker after regenerating from a Kaioken. The Kaioken makes one combust or something like that right? Wouldn't Cell just be devastated in a fight? Right at that moment he could be finished off, regeneration or not.

[LuckyCat]

No one uses Kaio-ken once they've achieved Super Saiyan levels. In Super, Goku explained that Super Saiyan and Kaio-ken aren't compatible because of how volatile the Super Saiyan state is. We see that Cell has at least the strength of a Super Saiyan and usually some sort of Golden aura. It's likely impractical and dangerous for him to use Kaio-ken.

Now if Cell ever achieved a SSBlue-like state, he might be able to use Kaio-ken just like Goku did, because that form is stable enough that it can support Kaio-ken.

Yes, he should be weaker after regeneration but he was stronger after regenerating when nearly killed to a cell..

I believe Saiyan zenkai combined with regeneration cancels out tiring effects of regeneration and swaps it with zenkai effect..

When cell did the kaioken he would have already demolished whoever he was fighting, so unless someone else finishes him after he has used kaioken recklessly many many times it's hard to say he will be killed off while recovering..

[Nejishiki]

Kaio-ken alone shouldn't heavily influence the Saiyan ability to grow stronger after surviving a near-death experience, I don't think. With Cell, it was only "near death" once in the entire Cell Game. I need memory assistance for this part but I don't believe Kaio-ken strained Goku to near death status when he used it. It was Vegeta who pushed him towards that state after his body was vulnerable. Additionally, Goku was maintaining a fighting state when continually using the technique against Freeza. When Cell used regeneration, it always had a large reserve of ki. Whatever it spent to use its inherited Namekian ability, except for potentially its final use of it, doesn't seem to significantly effect its ki because it usually had so much to spare. If anything, that's why it seems as if its strength doesn't increase after bodily harm if its cells were combining effects.

Cell doesn't have KK for the same reason he lacks Oozaru: he'd win by default by having either of them. And no, Super's moronic explanation doesn't count for shit as far as I care.

[LightBing]

Knowing the technique doesn't mean he would be able to use it, which is how I explain it in-universe.
Tenshinhan, Yamcha and Chiaotzu didn't learn it while trained by Kaio, I assume because they weren't able to master it. Even Kaio who created it couldn't do it. Piccolo I don't think had enough time to be taught so I'm excluding him.

This supports the technique being incredibly difficult. Which makes sense since it's one of the best techniques there are. Another example of a high level technique is the Kikoho, nobody else was able to emulate it. Contrary to other techniques Tenshinhan used, which other characters made their own. Just to give an example.

[Tsufuru]

the same reason he didnt use spirit bomb.
toriyama forgot or simply didnt want to make him use it.
in-universe, there is no reason not to do it.

[Tsufuru]

sry for double post but there is maybe a reason.

goku learned kaioken while dead and gero couldnt see how he learned them so he was not able to make cell use it.
i assume he saw how the other z fighters learned their atacks so he knew how to make them for cell.
but if gero's computer simply saw them once than its another story.
