All written in a notebook
Seriously, I love science fiction, and I was thinking of writing a book, the possunians were completely created by me, with a 20 months calendar , atmosphere details, and even political and technological level and biology and botany possuna
he is very strong in relation to humans, but is not so strong, there are certainly stronger species , the exoskeleton which protects some things, such as pressure, but in a limited way, a possunian not survive a black hole, but could walk with some difficulty and perhaps fly (he has wings ) in Jupiter, he was using a breathing device , its resistance is like a medieval armor protects against knives and swords, but is useless against a bullet
I think you meant that I copied the tardigrades , in fact, possunians were always thought of as being arachnids of about one meter tall , with a tail with a thorn , its strength is only equivalent to the a spider 1 meter, not is OP , and your body does not use water , but similar liquids
And custom building an organism is way better than just plopping even a super-OP animal like you're talking about down on a planet.
Tardigrades are really small, and aren't large animals like the ones your system uses. Even with stuff dissolved in it, water will definetly freeze at 0K.
They led one group tardigrades into space and exposed them to the vacuum of space for a while , and then brought back more than half survived .
it does not need water exactly , but the nutrients dissolved in it , so drink distilled water is bad , and there are substances that prevent the water from freezing at normal temperature
on earth it is possible for a few minutes , why this would not be possible for an alien adapted to a cold planet survive in these conditions normally?
Yeah, but that's for only a few minutes.
