In the mythology of the Yoruba, Eleggua is the god of the crossroads. He has many names: Elegba, Elegbara, Eshu, Papa Legba, Exu. He speaks all languages and serves as messenger of the gods, similarly to the Hermes of Greek mythology.

And some prior research:

Eleggua is a trickster who likes to play practical jokes on both mortals and gods. In one pataki he wears a cap which is red on one side, white on the other side; As result of this nobody can agree what is the colour of his cap, and he causes discord.

This god appears to walk like a crippled man. This is because with one leg he walks in the real world, and with the other in the spirit world. He is both young and old; Sometimes an old man with the head of a child.

In the Brazilian religions Umbanda and Quimbanda there are similar spirits called Exus. They are probably not the Yoruba god, but spirits who adopt similar qualities. Umbanda and Quimbanda are spiritualist traditions that work with dead spirits as well as orisha.

The spouse of Exu is Pomba Gira. There are many Pomba Giras, as there are many Exus. And for example in Brazilian Quimbanda, there is a spirit known as Exu Dos Cabeças (“Exu of the two heads”). Half of him is the male Exu, and the other half is fused together to the female spirit.
