I'm a friendly alien. I wish no ill will to humans and find them interesting even if their biology and traditions are frightening at times like the fact the eat the class 3 chemical weapon known as Caspian as a condiment or that they breath Oxygen a chemical compound known for setting those who breathe on fire. What I think is most frightening is that they use X-Ray machines and microwaves. Proving themselves to be immune to some radiation meaning most alien weaponry would be useless to them
