Which Assassin's Creed game features Edward Kenway as its protagonist?

Assassin's Creed IV: Black Flag features Edward Kenway as its protagonist.

Edward Kenway is a Welsh privateer and pirate who becomes involved with the Assassin-Templar conflict in the Caribbean during the early eighteenth century. His ambition initially centers on wealth and status, but his experiences gradually change his relationship with freedom, loyalty, and the pirate life.

Black Flag is especially known for combining land-based assassination missions with open-sea exploration. Players sail the Jackdaw, attack ships, gather resources, and visit Caribbean locations such as Havana, Nassau, and Kingston.

Edward is also the grandfather of Connor Kenway, the protagonist of Assassin's Creed III. That family connection is why the two games share characters and historical context, but they tell stories in different periods and regions.
