1986A was a timeline created as a result of the actions of both Marty McFly and Emmett Brown in 1931. By removing Arthur McFly from the area, this allowed Irving "Kid" Tannen to become ever more powerful, eventually resulting in a crime family that was the fifth most dangerous in California. In this timeline, Biff Tannen had two brothers, Cliff Tannen and Riff Tannen. On behalf of Kid, they beat up citizens of Hill Valley when it came time to pay up, creating general terror and eventual abandonment of the city. It was later replaced with a corrupt, totalitarian society in another alternate 1986 that was made when Doc and Marty went back to 1931 to fix the timeline.
