Loki, based on the myths where he wears Frigga's** feather cloak and transforms into a bird. Now THAT is wearing your mother's drapes! Took the hair from the new action figures of Loki they previewed at a toy fair.

**Certain sources say the cloak belong to either Freya for Frigga as they both own feather cloaks, but I remember a version where he borrowed one from Frigga in "The Children of Odin" by Padraic Colum.
