Her association with the marketplace, and more specifically with the gates of cemeteries (as opposed to the entire underworld), reveals her in her aspect as facilitator of transition. Oyá, when danced, often has a horse tail. Her clothes have all the colors but black. She has a face expression of really big and open eyes, and she breathes and blows up her chins, and often screams.
She is closely associated with many Orishas, but most especially Chango, Oggun, Oba (Obba), Yewá/Euá and Ochún/Oxum. Oya is believed to have been Shango's favorite wife. She is also called "the one who puts on pants to go to war" and "the one who grows a beard to go to war".
As the deity of the wind, Oya manifests in Creation in the forms of sudden and drastic change, strong storms, and the flash of the marketplace. Her representation of natural disasters and death is not as arbitrary as it may seem, these factors often serving as a means of creation for her.
