Sorry BL, but they are actually quite common in folklore. The only thing more common that is possibly alien is "the grays" and that is the most popular verion of an alien race. Looks like you just wanna avoid it.

Actually, the second most common is the Nordic, which is the most common in Europe.

And now that I remember what a Nordic alien is (a hybrid between human and alien) I begin to wonder if Boa is necessary on its own. Just a thought though.
