Anyone can compress their chi and hide
In universe 7, it's a technique unique to the earthling martial artists and a few others. That's why they were so effective on Namek. The raising and lowering of ki in general is a component of ki control, which is something Vegeta first learned from his contact with the earthlings. It's a technique that Cell inherited. Clearly, not everyone can do it as it's a learned skill.

What I meant was I assume there's other benefits to him to wanting to complete himself and not just absorbing enough humans to get an equivalent amount of battle power.
There could be but what's presented is just a massive power boost and maybe a few techniques. His protocols also change, as once he reaches higher levels he is no longer interested in absorbing humans. The human absorption may just be linked to an overall survival protocol.

I'm just speculating on things like ki control and smarts. We don't see him take a written exam before and after he reverts, it's speculation on my part.
Right! I see what you mean, but there's not a ton of evidence. His intelligence seems pretty standard throughout all forms. He just seems to gain some sort of dignity/haughtiness in his final form.

I don't think absorbing people could make him stronger then perfect, future Cell should have just set his sights on that route eventually when he realised the androids were gone but he even travels back to the past to get them, even though after killing trunks he has all the time in the universe with no chance of ever being caught or killed to his knowledge.
Considering what he gained from absorbing only a few thousand humans, it stands to reason that he could eventually overcome his perfect form if he continued to do so. It's just a slower and much more ineffecient way of doing things. If he combines this method with his zenkai then I'm confident he could make comparable power gains to what he made by absorbing each cyborg. It's just, it'd likely be slower.
I say this because the show hasn't shown any limitation on how much biomatter Cell can absorb or even if his previous forms have limits.

There must be some upper limit, I speculate eventually his first form COULDN'T contain more power without evolving, the other forms increase his carrying capacity.
Nah. Firstly, there are no hard or permanent limits in Dragon Ball. I always thought this, but Super is constantly confirming this for me. The only limitation, and this isn't even set in stone or even consistent, is the rate of growth for some characters/races. Cell isn't a robot. He is a chimaera-like creature built in a lab, but his biology allows him to access spiritual energy. As long as he has access to this and a reasonable amount of willpower and desire to increase his strength, he'll increase his strength. His biology even encourages this at high rates of growth.
I'm not adverse at all to what you're theorizing. It's a neat idea even, but it's just that what's been shown of Cell and DB in general doesn't really support this. The only way I could see this is if Gero for some reason placed a directive in Cell's genetic programming to force him to limit his strength, but again there's nothing shown in the show to even hint at this.
I could even maybe see the cyborgs unlocking more access to certain genetic traits like some sort of video game skill tree

but again it's just speculation without a shred of evidence.

Perhaps he's self destruct like Cell games Cell or Yakon or maybe the biomass wasn't strictly additive in battle power terms and was something like a video game mechanic where humans became green cons and no longer gave him EXP points, I dunno.
That makes sense to me. Like I said before, it's a good idea, but its not supported by the show. But I wouldn't be mad if tomorrow Toriyama-san said that this was how Cell works. It would fit.
TobyS wrote: Tue Dec 15, 2020 8:01 pmOut of universe Toriyama never planned past SS2 Gohan levels or power so it wasn't something that would or could have happened I think.
The story is very simple. If Cell somehow lived past that arc, his power would be like everyone elses. He would continue to grow in strength and if Frieza and #17 are any indication, he would get incredibly strong in just a short amount of time. If he saw his rivals getting stronger, his pride would demand that he train too.
Big fan of the characters of Dragon Ball, all of them, especially formerly prominent sub-characters. -__-
