"Question: Isn't a none-breathing race suppose to be fine with any atmos type?
Can there be a race the breath every kind of Atmos?
I mean, look at the Dopplergangers, droids that don't need atmos to live, so they should be perfectly happy with any kind of atmos since they don't need any........"

Well, there is pressure. Any vacum-adapted race would probably not do well in earth-normal atmospheric pressures.
