Matt Ryan provided Edward Kenway's voice and performance capture in Assassin's Creed IV: Black Flag. Ryan's portrayal anchors the game's pirate protagonist as he moves between privateering, piracy, and the Assassin conflict.
Edward Kenway is a Welsh privateer and pirate, and he is also the father of Haytham Kenway and grandfather of Ratonhnhaké:ton, the protagonist of Assassin's Creed III. This makes him part of the Kenway family line that connects several major games.
Matt Ryan is also widely known for playing John Constantine in television and animated productions. That association can cause confusion with other Assassin's Creed performers, including Roger Craig Smith, who voiced Ezio Auditore, and Michael Fassbender, who starred in the 2016 film.
