Which Assassin's Creed game introduced the Egyptian Medjay Bayek as its protagonist?

Assassin's Creed Origins introduced the Egyptian Medjay Bayek as its protagonist.

Released in 2017, Origins is set in ancient Egypt during the final years of the Ptolemaic Kingdom. Bayek of Siwa serves as a Medjay, a traditional protector of communities, before becoming involved in the events that lead to the formation of the Hidden Ones.

The game explores Bayek's partnership with Aya and their response to political manipulation, personal loss, and the growth of an organization opposing the Order of the Ancients. The Hidden Ones are presented as the early form of the Assassin Brotherhood.

Origins is distinct from the later Greek setting of Odyssey and the Viking setting of Valhalla. It also changed the series with role-playing mechanics, character levels, equipment statistics, and a larger emphasis on exploration across Egypt.
