in fact, the only thing that changes is the condition of my planets , but if you would be more comfortable if I had all these features fine, but still feel comfortable in the cold , in my saves has a civilization that lives in a magmatic planet and obviously they resist heat up to a point ( 800C ) although not advanced enough to come out of the planet
our clothes protect us from extreme temperatures and toxic gases , in addition to increasing our strength , however mobility is reduced , preventing of using the suit in battles
the possunians use atmospheric costumes when they are in an airless controlled environment , they are very demanding on the air they breathe , our immune system is weak , but we control the air of our planet , the only ones possunianos still has immunologically resistance are the poor , miners , farmers and gravediggers .
That sounds good. I just don't like it when people try to solve everything by giving their people inherent abilities rather than trying to work out the problem scientifically.
A compromise: The possunians naturally don't have these abilites and are more likely to have naturally evolved, however it is very common for them to enhance themselves with mechanical armour that allows them to survive in these extreme places.
Yeah, but you should balance out your species, because as it currently is they are completely OP.
even on earth there are animals that live in colder places than -50C
an alien is perfectly possible to look something earth and have a completely different biology, for example a giant insect capable of surviving temperatures to freeze oil
This depends on how you define life, it shouldn't be too hard to create creatures that could survive 0k, but those creatures would seem very different to what you might call "life".
That is still really cold for a living creature. -50C would be more realistic.
