Cybertronians are more like "machines" than organics at every glance. We're alive, if not by your definition. But yeah, most of us have armor and shielding to protect us from things like radiation. I don't know what organics use, if anything, so might be best to sit this one out and let us handle it.

What is it you think it is? And why would just shooting the slag out it be such a bad idea?
