In the vein of this question here, I was wondering about the practicality of the mythical Grecian concept of the Hecatonchires. Forget, for a moment, that these monsters are supposed to be invincible. Now, wonder how one such monster (with 50 heads and 100 arms) could be defensible.
I imagine a head array (all of them in a line, ear by ear) to be most inefficient, especially if the opposing side has snipers:
_ _ _ _ _ _ _ _ _ _ / / / / / / / / / . .\ *Can somebody say headshot times 50? \_\_\_\_\_\_\_\_\_ U_/
Then, consider also that we need to fit 100 hand/arm mechanisms on this thing. If all of these limbs were located on the side of its torso, at the very least its midsection would be a huge, bullet-soaking pillar--even before we give each arm enough room to swing up and down without interfering with its neighbors.
So, assuming that this creature must be a bipedal humanoid-ish monster--i.e., no Mr. Fantastic's elastic limbs; there are bones in this thing's arms, although the length, number of elbows, etc. are debatable--how should this creature's parts be arranged?
In other words, what is the most practical way of constructing this ludicrous monster such that its extra heads and arms are useful (e.g., having the skulls arranged like parapet stones), and so that it could properly be deemed a formidable foe even in modern combat?
(Note: I use modern warfare to exemplify the weakness of a "copy a human 50 times horizontally" design, though the Hecatonchires need not be foisted into our space-time continuum. Even in the mythic past, however, a monster with a spaghetti of flailing limbs, and for whom armor construction is nigh impossible (Hephaestus notwithstanding) still seems hardly defensible. Also note that what these things would be wielding in their 100 arms is another question altogether).
