Through the awesome powers of Evolution.
All the men who didn't survive died. Those who did progressively became more successful at it overtime.
As to why a Dragon wants to impregnate a man, perhaps its the particular hormonal cocktail that men just have. Maybe its that Women simply die. Pretty gruesome stuff really. Maybe dragons just happen to be very open ...
He can carry the fetus like a tumor, then have it surgically delivered at term.
A 67-year-old male was hospitalized on 26 September 2007 because of a
large, paucisymptomatic retroperitoneal tumour. The patient had been
presenting progressive abdominal swelling, weight loss and asthenia
for three months.
Multiplanar reformations (MPR) show the whole tumour ...
The 'female' dragon is a transfemale who has not fully transitioned yet and therefore has all the parts needed to father a child.
The 'male' human is a transmale who has not fully transitioned and therefore has all the parts needed to get pregnant.
It's a real thing today pregnant trans couple. So definitely 'science based.'
Dragons Lay Their Eggs inside Living Creatures
Dragons are similar to those wasps that lay their eggs inside other insects. Usually without consent.
It doesn't matter if the host is male or female. Heck it doesn't even matter what the host's species is. The foetus does most of the work keeping itself alive. When it is strong enough it makes its own placenta ...
In order to stick to walls, in a way that is useful for walking, they would need to be light. One way to achieve this would be to have a large, methane-filled bladder somewhere in their body, which would allow them to be floaty enough to stick to walls. This would probably entail a large torso, with skinny limbs as a way to further reduce weight
In addition to skin discolouration mentioned above, they would likely be significantly smaller than their surface cousins within a few generations:
Early animal studies by Cowley and Greisel over three generations, and by Chow over two generations, demonstrated that the nutritional status of the rat mother had effects on the growth and development of ...
What would I do with them with my limited warfare understanding?
Here is why they are the prefect skirmishers. First they are taller which means they can stand behind your infantry and shoot at the enemy.
They are stronger which means they can maintain a higher rate of fire with better damage, more on that later, and lastly as they are ...
Have them act as vanguard in a charging unit when laying siege to enemy strongholds. The giants will be living battering rams. Each giant will be supported by a bunch of mounted archers preferably, to provide cover fire as the giant charges. It will at least justify the cost of armor.
Have them in the rear operating giant-specific ballistas or catapults or ...
There are many ways that would proparly create different type of stories.
They can carry injured soldiers back to safety with speed. Considered blessings of God and doing humane work would be reasons not to attack them. Being able to carry a person twice faster to receive surgery would be huge for the survivability. While the giants are so rare they ...
In order for the sticky gecko legs to work, the toes would have to be very long and wide in order to support the weight of a human sized animal. In addition to this, it would have to be relatively thin and have bones that are either hollow or very slim.
Your creature will probably have tiny bristles, arranged in ridges about 5 micometers wide, almost like fingerprints. You'd need to work out the math to estimate the holding power of these things.
You don't need 4 extra eyes to see infrared. All you need are an abundance of rod structures in the retinas of the first four eyes. Of course, it's your ...
In the case that the robots are indistinguishable from humans, then they are basically clones. In other words, those robots are humans, and humans are robots. In that case, it shouldn't be too hard to convince a child that he was born of cloning.
Of course, you'd face the same slavery charges whether you are selling the robots or the humans.
