"Bob, do something!"

Overwatch is a team-based multiplayer first-person shooter video game developed and published by Blizzard Entertainment, which released on May 24, 2016 for PlayStation 4, Xbox One, and Windows. Described as a "hero shooter", Overwatch assigns players into two teams of six, with each player selecting from a roster of nearly 30 characters, known as "heroes", each with a unique style of play whose roles are divided into three general categories that fit their role.

B.O.B. was the butler of Elizabeth Ashe's family. Her parents paid little attention to her, and care of their daughter was mostly relegated to B.O.B. Thus, B.O.B. was there when Ashe's parents weren't.[1] He was there when she partook in target shooting on the family estate, and was there when Ashe was released from prison.[2] Throughout her youth, Ashe spent a lot of time talking to B.O.B.,[3] even though he apparently couldn't talk back.[4] When Ashe founded the Deadlock Gang, B.O.B. remained at her side and partook in heists himself.[2] At some point after joining the gang, his chasis was fitted with armour plating.[5]
