Swamp Hermit

Swamp Hermit is a character in The Werewolf of Fever Swamp. He was believed to be the werewolf after Grady hears stories about him from his friends Will and Cassie, though his father tells him he's harmless. He didn't make a positive impression when he played a prank on the children, laughing and shouting "I'm the werewolf!" while chasing them. He stops when Grady trips on a root and explains he was joking. He makes a remark at Grady to watch his dog, Wolf. After it's revealed that Will was the werewolf and was chased off and killed off by him, the swamp hermit found Grady, wounded by an attack by Will and took him back to his house.

TV episode

In the TV show, the swamp hermit captures Grady in a net, believing him to be the werewolf. He finds out he was wrong when he realized that Grady didn't change under the full moon. Later that night, he finds out who the real werewolf is and tries to capture it in the net again. He shouted at it, "You took my wife and children, everything I ever loved! I swore one day I would take your heart the way you took mine!" But he realized, to his horror that it wasn't the werewolf, it was a deer. Will killed him after he told Grady to run for it.
