Which Assassin's Creed game introduced the eagle Senu as a scouting companion?

Assassin's Creed Origins introduced the eagle Senu as a scouting companion.

Senu accompanies Bayek throughout Origins and can be controlled from above to survey locations, mark enemies, identify objectives, and locate points of interest. This aerial perspective became one of the game's defining exploration features.

The mechanic fits the game's ancient Egyptian setting and Bayek's partnership with animals. Senu is not simply a decorative pet: using the eagle gives players information before entering camps, tombs, forts, and settlements.

Later games developed related bird-companion systems. Assassin's Creed Odyssey features Ikaros, while Assassin's Creed Valhalla uses the raven Synin. Those names are sometimes confused with Senu, but Senu is specifically associated with Origins and Bayek's Egyptian adventure.
