Well, there is no biblical descriptions for the "real form" of Archangels. Then again, Supernatural isn't one to go by the Bible (Archangels being the second lowest form of Angel, right above the regular Angels......Seraphs are the highest....in fact:

Seraphim Cherubim Thrones Dominions Virtues Powers Principalities Archangels Angels)

The only ones with physical descriptions are:

Seraphs - There are only four of them. They have the heads of eagles and six wings. They use the wings to cover their bodies, because their bodies burn with such intense light and fire, anything that looks upon them (including other angels) will be incinerated.

Cherubim - The guardians of Eden. The have 4 faces - a man, an ox, a lion, and an eagle. They have 4 conjoined wings with eyes, a lion's body, and ox's feet.

Thrones - Wheels within wheels, each rim covered with eyes

Dominions - commonly pictured as humanoid with wings

Principalities - Wear a crown and carry a scepter

If I had to put a picture on an Archangel in the Supernatural Universe, I'd equate them with Seraphs......Anna (an Angel or Seraph) incinerated everything that looked upon her once she regained her grace, so I imagine an Archangel would be even more intense.
