This thread is the result of lacking alcohol.

From Claymore's ability to regenerate the way the do, to their pain tolerance, and strength all the way down to Youki manipulation, this all falls into the category of how a Claymores body functions.

What is it, that makes Youki so powerful? If we could on what kind of a symbiosis is it?
Lizards, once their tails are cut of (or any limbs) regenerate them after a certain point of time.

Regeneration, in short (Kolox correct me if I'm wrong here) is creating (or better said re-creating) lost or degenerate limbs in a way similar to the way they were created in the first place.
In the 70s, doctors found out that children up to 10 years old can partially regenerate lost fingers unless the skin flaps are put over the wound (standard procedure).

What makes a Claymores regenerative abilities the ways they are speaking in a hypothetical biological way? How come a Deffensive's healing ability are THAT superior to an Offensive warriors?
We know Defense warriors are born while the bonding procedure as are Offensive warriors. Defensive warriors have a strong will to survive (call it an instinct, for explanatory purposes), while Offensive warriors have a killers instinct.

Does a Claymores healing ability rest that much on her psychology?
Taking Deneve into example;
Yes, she is partially awakened, but we've seen how every other Claymore has a different ability when (or if) they Awaken. Deneve's is a very enviable ability - in the blink of an eye she made a brand new arm (incomplete) seconds after she lost her old one. Maybe her will for her life is THAT strong.

Firstly I would like to say that regeneration at the speed of Deneve is impossible even for Porifera and Hydrozoa, and of course absolutely impossible for mammals.

Secondly, I can imagine mammal regenerating a limb like claymores do. The certain genetical systems should be activated for that. Some amphibians show the ability of this kind, so it is not entirely impossible.

And yes, healing depends largely on a persons will, in fact, psycological difference is very important when it comes to regenerating wounds for humans, so i would imagine the same being true for claymores.

Well take a look at starfishes. If you cut them in half each half will grow an entire new body. Meaning now you will have two starfishes. It might be a bit similar to that but not as effective. Then again starfishes aren't mammals.

I look at it completely differently. Yoma ability is not regeneration, it's shape shifting. They can change the look of their body perfectly, to even resemble a human of different mass and height. So why would I change my body so the wound of a sword would disappear, like modelling a clay ?

It's all about changing shape, regeneration is by-product of it.

So why can't claymores shape shift?

But they can - especially the Defensive. Look at Jean, she changed the shape of her arms to make that corckscrew move, or look like Ophelia twisted her head in 360 degrees. Claymores have this ability far weaker than Awakened beings and yoma.

I mean to the Yoma extent. I mean changing your hair color, eye color and even gender. Thus humans wouldn't know about Claymores.

a) They can change their eye colour
B) They are only half-yoma, it's only logical they have only half their power
c) Apparently yoma needs to eat the human to change into him
d) Considerably, Yoma might be genderless so they just might appear like they are male or female but having nothing to do with being of that gender.

Also why would humans not know about Claymores ? Isn't it already quite hard to determine who is claymore if you have suppresent pills ? Clare proved that, Galatea proved that.

Moreover, the better shapeshifting to the extend of yoma and even stronger appears when Claymore awakens, they can change shape completely because they are using 100% of the yoma power and non-existent of human one. It's human factor that does not allow them to shape shift as much as they yoma can.

Correct me if I'm wrong but to regenerate a lost limb requirest the claymore to envision the lost limb once again right? I don't remember where this was mentioned but I recall something like that being said by I think it was Galatea.

So defensive warriors are actually taking advantage of the shape-shifting abilites when they are regrowing lost limbs are they not? They have to envision the lost limb and use their yoki to slowly peice together the lost limb using thier mental blueprints of the said limb. I guess it's rather difficult so since they are also fighting the 'monster' half of their bodies at all times from taking over.

Guess that wouldn't be far-fetched explanation, considering how Deneve said that regeneration really deadly wounds can get you to awaken - it's like battling with that "monster" and loosing in the end if you relied only on yoma part.

Defensive concentrate more of keeping control of the yoma part than unleashing it's power. Offensive are more about quick unleashing power than specifically controlling it. Yoma and Awakened being shouldn't have categorise like "Defensive" or "Offensive" since they are not bothered by their human part.

It just that yoma is already finished product, with no chances of becoming stronger. Claymore have that potential. Awakened being don't have such either, but if they became strong when they were claymores they are strong as awakened beings.

That being, in use of shape shifting

Trainee or Poorly made claymore < Yoma
Yoma < Ranked Claymored
Ranked Claymore < Awakened Being (always, even if Claymore has some superior skill, his regeneration or change of body will never be near of AB)

So, in short Offensive warriors have a weak (so to speak) will, that doesn't allow them to have control such a greater extent over their own Youki and bodies to not regenerate limbs. Ok, got it so far.

I wouldn't say that they have a weaker control over the yoki in their bodies. Control over that energy comes from experience and each Claymore will slowly learn how far they can push themselves before they're in danger of awakening. I would say that the power evolves differently based on the mindset of the Claymore themselves, it has been said before many times, whether a warrior is classed as an Offensive or Defensive type depends on their state of mind before the change. In their heart, was the person more concerned as a human with hiding from the yoma that attacked them or getting revenge? Of course everyone wants revenge but it's their basic nature that counts for the most, and I think the yoma flesh implanted in them responds on an empathic level to this need.

Thus why Offensive types have the potential to become physically stronger and faster while the Defensive types will have superior regeneration capabilities. No one is better than the other, it's simply different. That being said, I think that whether an Awakened Being was formerly an offensive or defensive type does matter because those who were formerly offensive types are still said to be slow at regenerating severed limbs. However, the key difference is that they can regenerate their limbs at full strength whereas offensive type Claymores are only able to regenerate limbs at their original human strength.

I agree with everything except for the last sentence - if Claymore was to regenerate with human speed, it would take weeks to get a wound close.

Nah, not human speed, but human strength. A defensive type can regenerate their arm to have their full Claymore strength whereas an offensive type's arm will only have the strength of an ordinary human. To regrow a full arm would probably take about a week, I think. Irene does say at some point.
