What was the name of the person in Revelation 19:12-13 who had flaming eyes, many crowns on his head, clothes dipped in blood, and a name written on him that no one knew but himself?

The Word of God

His eyes were as a flame of fire, and on his head were many crowns; and he had a name written, that no man knew, but he himself.

And he was clothed with a vesture dipped in blood: and his name is called The Word of God. Revelation 19:12-13
