I thought Michael was the only Archangel? He's the only one the Bible calls as such, anyway.
Oh, I thought Gabriel was?

Angels aren't always obedient to God: Satan was created an Angel after all.
Yeah, I was thinking you know how when you think of Satan you think of him being ugly and evil looking. Well he is a fallen Angel, so I guess he would actually look pretty good! Hmm...and I guess that would help with his appeal and getting ppl to follow him.
