Barbara (Barb), sadly, doesn't survive the "Stranger Things" universe for very long. Abandoned by her best friend, Nancy, so she can go off with her then-boyfriend, Steve, Barb is attacked in the pool outside Steve's house. After bleeding into the pool from a minor injury she sustains during the party, the Demogorgon drags her into the Upside Down.
One of the subplots of season one follows Nancy's attempt to find her friend. Because Will, the Demogorgon's first victim, is still communicating with his mother from the Upside Down, fans are hopeful throughout the season that Barb will also emerge alive. Sadly, that is not the case, as her death is confirmed when her body is found in the Upside Down.
While Barb isn't technically alive, her presence is still deeply felt because she makes frequent appearances in flashbacks, an image that haunts Nancy to this day in season four due to her guilt over leaving her friend behind.
