Angel Wings

Title card for Season 9.

Title card for Season 14.

Angel wings in the Season 15 title card.

Angel wings are/were the primary mode of transport for angels, allowing them to teleport anywhere on Earth, Heaven, or Hell. Their wings make the sound similar to cloth fluttering as they approach or depart via teleportation. An angel's wings cannot be perceived by human eyes, however a silhouette of the wings can be seen if an angel chooses to reveal its power. When an angel is killed, their body and wings will leave scorch marks on their surroundings. After the angels were ejected from Heaven by Metatron, the wings on angels were either burned completely off in the Fall or were left as mangled vestigial limbs, preventing the angels from teleporting. Aside from Metatron, who cast the spell, archangels were the only ones unaffected by Metatron's spell including Michael and Lucifer, who were both locked away deep in Hell in the Cage, and Gabriel during his imprisonment by Asmodeus.

Angel feathers also hold special properties, specifically being a key component to the time traveling spell first used by Henry Winchester in 8.12 As Time Goes By. A single feather also holds rejuvenating properties for an angel, as shown by Lucifer, who used one of his fossilized feathers to temporarily repair his deteriorating vessel, Vince Vincente.
