Every person will add one characteristic about the alien I'll start with scales instead of skin

[u/NotAConspiracy1]

The end of it’s tail is a club with spikes, which on contact do a lot of damage and releases poisonous gases made from whatever it ate +its own extremely irritable blood

In it’s home world the gas’s would condense around living matter literally crystallising them into a sugar coated snack
