Who is the playable Assassin's Creed III protagonist known as Connor?

The Assassin's Creed III protagonist known as Connor is Ratonhnhaké:ton.

Ratonhnhaké:ton is a Kanien'kehá:ka man who adopts the name Connor during the American Revolution. The game follows his efforts to protect his community and oppose Templar influence while the colonies fight for independence from Britain.

Connor is the son of Haytham Kenway, the playable character in Assassin's Creed III's opening sequence. His mother is Kaniehtí:io, also called Ziio. Achilles Davenport trains Connor in the Assassin tradition and helps him establish a new base at the Davenport Homestead.

“Connor” is the name most often used in marketing and everyday discussion, but Ratonhnhaké:ton is his birth name. He should not be confused with Haytham, his father, or with Connor from other fictional works.
