Loki as an Old Woman
In Norse mythology, Baldur is killed by an arrow wrapped with mistletoe (Baldur's only weakness), which is shot by his blind brother Hodur. Hodur is tricked into doing so by Loki. When Baldur is sent to the Spirit World, Hela says she will give him back if everyone weeps for him. Loki dressed as an old woman refuses to weep so Baldur is lost to the Sprit World.
