The Watcher is a demonic forest spirit and an antagonist in the Are You Afraid of the Dark? episode "The Tale of Watcher's Woods".
He was portrayed by Tom Rack, who also portrayed The Security Guard/The Sheriff, in the episode "The Tale of the Pinball Wizard", in which he also was co-writer of the episode.
As the forests were desecrated over the years, the Watcher decided to protect his forest by casting a spell on it and having it randomly appear. His most recent victims were three girls who blundered into his forest and couldn't find a way out. Their whistles were the only trace of them that ever was found. It was only when each of their whistles was returned that they could finally rest.
