Which Assassin's Creed game introduced the Eagle Vision ability's successor, Senu, as a controllable eagle?

Assassin's Creed Origins introduced Senu as a controllable eagle and successor to earlier Eagle Vision systems.

Senu is Bayek's trained eagle in Origins. By taking control of Senu, players can scout settlements, mark enemies, identify points of interest, and survey the surrounding landscape from above. This aerial reconnaissance replaces the earlier series convention in which Eagle Vision was primarily an ability used directly by the human protagonist.

The change reflects Origins' broader redesign of exploration. The game presents a large, open version of Ptolemaic Egypt, so aerial scouting helps players understand camps, roads, ruins, and wildlife before entering an area. Bayek can also use Senu to locate targets and support stealth planning.

Odyssey and Valhalla continued the animal-companion approach with different birds, which is why the feature is sometimes attributed to those games. Origins is the title that first introduced this specific controllable-eagle system, and Senu is uniquely associated with Bayek's adventure.
