What is the name of Assassin's Creed Origins' main protagonist?

Assassin's Creed Origins' main protagonist is Bayek of Siwa.

Bayek is a Medjay, a traditional protector and lawkeeper from the Siwa Oasis in ancient Egypt. The game follows his search for the people responsible for a personal tragedy and shows how his experiences contribute to the beginnings of the Hidden Ones, the organization that later becomes the Assassin Brotherhood.

Origins was released in 2017 and is set during the final period of the Ptolemaic Kingdom. Its world includes Egypt, Alexandria, the Sinai Peninsula, and parts of Libya. Bayek's wife, Aya, is also a major character and an important founder of the Hidden Ones.

Players can confuse Bayek with Senu, his eagle companion, or with Aya, whose role is substantial. Bayek remains the playable protagonist for the main campaign, while Senu supports reconnaissance and exploration.
