1. Its callogen in a different structure. That is like saying graphite and diamonds are "just carbon" and therefore the same thing.
They are different.
2. Human skin ranges from .5mm (eyelids) to 4mm (palms). 1 layer of Kevlar isn't going to get cut by paper. In fact, thickness doesn't matter when it comes to cutting. 100mm of skin will get cut just as easily as .5mm, under the same circumstances.
3. No, we are discussing both. Because we have always been discussing both.
4. Apparently you aren't smart enough to know what a common saying means. Or smart enough to google it.
5. No, it was an example that proves a point. By the same token the fists aren't exactly "boulders" compared to the bear. As you where talking about general examples with "punching down being easy", it is fair to compare it to another general example.
6. That doesn't mean a lot, when the bear is a sentient and trained fighter while the fly is not. It proves the concept.
7. Because he is a shapeshifter who is normally a lot smaller. He can't carry around armor that is two times as large as he is, and he can only stay in that shape for a minute. Or do you expect a size 0 to carry around size 2 armor and weapons his entire life, just in case he needs to get into a fight?
8. No, I am saying that the Goliath does not have a massive advantage over a bear in a fight, and more generally, that having the size advantage doesn't mean a lot in this game.
9. Then why would you try to go straight through the rib-cage? I am saying that you would have no reason to do things the hard way when you have many options when killing things with your claws. If you are attacking the chest, you don't have to get past the ribcage to get the enemy down. The rip-cage gaps would also be lengthened, smaller claws likely could simply go past them the same way blades to. Mechanically, blades are no different then bladed weapons.
10. No you don't. I can't think of any way you would even think that was possible. It takes less then a second to land a punch, trying to correct it would be like trying to correct an actual thrown object.
11. What part is assuming? Its literally their power to transform? I'm starting to think you are a robot stringing random words together in an attempt to pass a turring test.
