William Joseph "BJ" Blazkowicz, "Billy" as named by his late Mother Zofia when he was a child, or just "William" by his spouse Anya, also known among the Nazis as "Terror Billy", William Joseph Blazkowicz is the protagonist of MachineGames's reimagining and reboot of the Wolfenstein series, inspired by the original version of William J.
