Deena Johnson is the main protagonist of the Netflix dark horror film Fear Street trilogy. She's portrayed by Kiana Madeira, who also portrayed Sarah Fier in Fear Street: 1666. An occasional member of Shadyside's high school band, the outspoken and self-sufficient Deena is the town's truest misfit. Already dealing with a break-up and a grim future laid out by her alcoholic father, Deena rapidly finds herself battling against a variety of even worse fates. Deena is a mostly calm teenager who was originally a sceptic who didn't believe that there was a curse on her town. She can also become defensive such as when she confronted Sam about how she saw Peter grabbing her butt during the vigil however since reconciling, Deena became much happier and content with her relationship. When in danger, Deena has a straight forward mindset and becomes very serious such as when she was being confronted by the killers or when she killed Nick to end the curse. She also does not mind confrontation such as when she confronted Sam about their relationship or about the Skull Mask Killer who she originally believed to be Peter. In the beginning, Deena doesn’t believe in the witch’s curse; she’s focused on cutting ties with her former girlfriend Sam, who moved to Shadyside’s rival town Sunnyvale. Deena then changes her tune when she realizes that the witch’s undead minions are targeting Sam for disrupting Sarah Fier’s grave. The first Fear Street film sees Deena, her friends Kate and Simon, and Josh attempting to save Sam from the curse. By the end of Fear Street: 1994, Deena and Sam are back together. Deena believes the curse is broken until Sam becomes possessed by Sarah Fier and attempts to kill Deena. The final moments of the film show Deena vowing to bring her girlfriend back from the witch’s clutches, setting the stage for the next two movies.

Berman's house for help on where to find the hand of Sarah Fier and reunites it with the rest of her corpse attempting to end the witch's curse.

Deena returns to the present and sets out a plan with her friends to kill Goode and end his deal with the Devil once and for all to save Shadyside. The killers follows Deena's blood and uses it to distract them from her long enough for the others to defend her while she goes after Goode, reciting the memories of Sarah to tracking him through the caves and gets tackled by possessed Sam until she subdues her and eventually confronts Goode. She is pin down by him who would frame her for the murder of her allies and get away with it, but Deena hears a whisper of Sarah Fier's voice from the heart of the Devil and in effort places Goode's hand on it to have him see to victims ever been harmed by him and his family before.
