David Adaven (or just simply "Dave") is a night guard who works at Freddy Fazbear's Pizza in Five Nights at Freddy's Fun Fair.
You never really see Dave's body. All you can see of him is a brief moment when you press a button. You can see his hand and forearm. His wrist has a scar on it.
- His last name is "Nevada" backwards, hinting at the setting of the game.
