In the Halloween DLC made by Fazbear Entertainment in the games and by SteelWool Studios in real life, Dreadbear is one of the new additions.
He appears in the opening hub, at the top of the "Curse of Dreadbear" line.
Dreadbear also appears in the game over screen, laughing at the player.
In Night 03, Dreadbear is a threat. He makes his way from the stage to the office. The player has to flash the light on the cameras to slow him down. If he gets to the office, he instantly destroys the door and kills the player.
Dreadbear in the "Dreadbear" level, is revealed to have a brain inside him, and the player has to put it inside Dreadbear.
Dreadbear sometimes appears in the main hub, as an easter egg.
Dreadbear's appearance is similar to that of the classic horror movie icon Frankenstein's monster, sharing properties such as screws stuck to his jaw and stitches all around the body. He's also similar to Nightmare Freddy in terms of his head shape, but with flatter teeth, thicker brows, and white eyes.
Like the nightmare animatronics, he supports five clawed fingers, but has three-toed feet that are similar in fashion to the toy animatronics.
- Dreadbear's original name was Franken Freddy.
- There is a theory that Dreadbear is the Bite Victim from Five Nights at Freddy's 4, or an manifeston of him.
