The Blackbird is the titular main antagonist of the short story Blackbird in Five Nights at Freddy's: Fazbear Frights #6 .
The Blackbird is a fictional character created by Nole and his friend Sam for the film they're making for their filmography class. Inspired by both the animatronics at Freddy Fazbear's Pizza and Edgar Allan Poe's "The Raven", the Blackbird was supposed to haunt the main character at night and force him to reveal his darkest secrets in the narrative Nole and Sam wanted to create.
With the help of his mom and his dad, Sam creates a costume for the character and meets with Nole on the set to start recording the film. Jokingly, they ask each other what their darkest secrets are. Nole reveals to Sam that he used to bully a girl named Christine (who was overweight and poor) when he was twelve, but despite declaring that he's not proud of it Noel doesn't seem to feel sorry for what he did at all, still finding his actions hilarious. Sam, being a victim of bullying himself, becomes furious and leaves the set with his costume after a brief argument. Later that day, Nole discovers that Sam had been ran over by a train and was declared missing when his body couldn't be found. While the search for him, which Nole participated in, is unsuccessful, black feathers and blood are found on the train tracks.
Nole blames himself for what happened, thinking that Sam got hit because he didn't pay attention to his surroundings due to his anger towards him. Shortly afterwards, Nole starts to perceive a presence following him everywhere, a feathered fiend always just out of sight. When attempting to sleep, he feels stuck in some kind of state between asleep and awake, getting attacked by the Blackbird, who always vanishes when a ray of light enters the room. He figures the Blackbird had somehow come to life or that Sam had come back from the dead to punish him for his past actions, haunting the Blackbird's costume, and that he's now going to torture and maybe even kill him. The attacks of the creature keep repeating whenever Nole tries to sleep, becoming increasingly vicious and still vanishing every time Nole turned on the light. Eventually he feels the Blackbird sitting on him, pressing against his chest and preventing him from breathing while he's stuck in his body, unable to move but still perfectly conscious. He feels like he's being dragged to another realm where the Blackbird would torture him, maybe forever. He's only saved thanks to his fraternity brother Ian, who breaks into his room after noticing his muffled screaming.
Following the advice of his classmate Amber, Nole decides he has to apologize to Christine, the girl he had bullied all those years a, hoping that would make the Blackbird stop haunting him. Still being followed his shadowy stalker, he finally manages to find Christine and gives her a heartfelt apology, finally understanding how horrible his actions had been. Christine decides to forgive him and the weight lifts from his chest, the Blackbird's presence no longer with him. Nole then receives a call and rushes back to his college: Sam was found, alive and with a broken leg, meaning The Blackbird wasn't him. The two meet again and reconcile.
When Larson enters inside Doctor Talbert's house and he sees Eleanor, she takes him on a tormenting trip down her own memories. After hopping between many scenarios, Larson ends up in a field near a railroad and he sees Eleanor spinning Sam, wearing the Blackbird costume, around and leaves him on the tracks. Larson, however, is able to change the outcome, pushing Sam out of the way and makinng him land in a ditch.
