Joe Baker is the main protagonist in the End of Zoe DLC chapter for Resident Evil 7: Biohazard.
Joe is the brother of Jack Baker. He lives in the nearby swamplands near the Baker estate, though is isolated from the rest of the family and unaffected by Eveline's control.
During the chapter, Joe discovers his niece, Zoe, shortly after the events of the main game and tries to find a cure to free her from Eveline's influence. To do so, he battles against the remnants of the molded creatures created by the Bakers and a mysterious creature chasing after them, later revealed to be a resurrected Jack. Joe ultimately kills his brother and is able to cure Zoe, after which they are found and extracted by the Umbrella Corps.
Although he can use firearms, Joe mostly fights with his bare hands, though later acquires an Umbrella Corps glove to increase his strength prior to his final battle with Jack.
