User blog comment:ImperiexSeed/Top 3 favored Supernatural Creatures/@comment-3481504-20120523032635

1) Archangels, for their nature and power, their near-indistructibleness, their immortality, their overall power capability. And their superiority to all other creatures BUT God and Death.

2) Cupids, but despite their low stature, I love their infatuation manipulation, which seems unique to ONLY them. They're practically Angels, they can teleport, have super strength, are invisible, etc.

3) Leviathans, for their ability to eat literally everything in their vicinity (except for Archangels), Cas equates it to eating "the entire aquarium", aka the Earth. with their immensely powerful jaws, and their ancientness.
