Who is the canonical protagonist of Assassin's Creed Odyssey?

Kassandra is the canonical protagonist of Assassin's Creed Odyssey.

Odyssey allows players to choose between Kassandra and Alexios as the playable Misthios, or mercenary. Ubisoft later identified Kassandra as the canonical character, while Alexios appears in the story as her brother and can still be selected by players.

The game is set in ancient Greece during the Peloponnesian War. Kassandra's journey connects family history, myth-inspired encounters, and the search for the Staff of Hermes Trismegistus, an Isu artifact with extraordinary longevity effects.

The choice of playable character affects presentation and voice performance, but the broad historical campaign follows the same main structure. Odyssey launched in 2018 and is one of the series' role-playing-focused entries.
