18 and 17's cybernetic design

[Legendary Saiya-Jin]

Just wondering, has anyone thought up of explanations/ theories as to what exactly their design is and how organic/ cybernetic they are?

For those who don't know: some guidebook I don't remember said, IIRC, their designs and energy cores were actually organic and not machine. This actually is very confusing since they show Android 17's blueprints in the anime with a robotic-looking skeletal design, but I guess that could just have been anime-only and their ki can't be sensed since it's assumed its as artificial as the robotic cyborgs.

Another reason why this is confusing is because 17 and 18 talked as if they had their own machine-like database, as if perhaps their brains were not entirely human; perhaps part machine, though, they couldn't detect ki like Android 16 could. Oh, and just some other questions to throw in for anyone willing to answer/ speculate about 17 and 18: do you guys think they'd naturally act like teenagers or the generic, emotionless machine stereotype they seemed to get in the beginning of the anime? They seemed a lot more like bratty teenagers in DBZ Kai in Future Trunk's timeline, but they seemed to show less emotions in the present (Could be wrong about that and maybe 18 just liked acting like a cold, robotic machine to Vegeta in general, lol); were they perhaps not given emotions in the present timeline that they would've had in the future? Also, do you think 17 and 18 knew about the Dragon balls like Future Cell and A-20 did?

Thanks.

After looking at 17's blueprints, Bulma says 17 and 18 are mostly modified only with organic materials, which is why Cell can merge with them on a cellular level. Kuririn also says in the Boo arc (when Goku asks about 18 being able to have a kid) that 18's just a human who's been "modified a little bit". If they had big clunky robot skeletons or whatnot, presumably Cell would have had trouble absorbing them like he did with 16. Though it's notable that 17 and 18 are the only ones he sucks up vacuum cleaner-style, and the fact that 18 gets spat out with her clothes intact and everything kind of makes Bulma's comment about Cell merging with them on a "cellular level" seem odd.

Do you think they have any mechanical additions to their brain, or... maybe they were brainwashed to know all these things about Goku by Gero?

I feel like they'd have to. Heightened fighting abilities and awareness perhaps, I don't think they were born super skilled martial artists.

Besides being a mad genius, Gero's brain seemed whole and regular except he could seem to detect ki like 19 could? I guess it could just be as easy as having such devices inside his body and translating it into his brain for him to mentally "see", so perhaps it could be the same for the twins? If so, I wonder where this machine-part with all this necessary data is stored.

I am absolutely sure about Cell reverting 18 (without wanting it) and that she was just a part of his system before. it does not make sense that he actually has both complete bodies in his own body all the time. Just like Goku in GT (though I don't like that scene) said he would have almost been digested
.

It makes sense that their modifications were done very intrinsically, on a cellular or even genetic level, because Shenron couldn't reverse the process.

As for their emotional states, Gero says he had recently modified them to make them easier to control. Of course, this didn't really work. When they were activated, I think they just played the part until 17 seized the controller.

If they were recently modified, I wonder what he did in the future that made them so different? Less modified somehow, since they seemed more emotional in the future timeline? (Well, anime-wise, anyway.)
