Crowley is/was Kerubiel
I know a lot of people have suggested that Crowley is/was various other angels (Baraquiel, being one of them) but I much prefer the idea of Kerubiel...
as wikipedia describes them:
Kerubiel is about Seven Heavens tall with a body made of burning coals that is covered with thousands of eyes. His face is made of fire, his eyes spark of light, and his lashes are lightning bolts. Fire spews forth with every word that he speaks, and he is covered with wings from head to toe. Thunder, lightning, and earthquakes are his constant companions
Crowley dresses almost exclusively in red and blacks, which is how burning coals look, he breathed fire in Heaven and regularly spits her words out when angry (fire spews forth-fire is often related to fury), and he can shoot lightning out of himself (again, he's angry, but we've not seem her do it when calm so we can't be sure he can't do it at any other time as well.)
He's also got yellow eyes... (his eyes spark of light). Light is often yellow/white when you think of it in your mind or is described. She also wears glasses... and we all know of the general idea of being called "four-eyes" if you wear glasses by bullies (covered with thousands of eyes)
Crowley also keeps the "K" sound from Kerubiel. it would be her way of holding onto her last piece of Heaven in some way
just a thought
