The Stag-Man, otherwise known as Deer-Man, was a Deer/Man humanoid that appeared in the episode "Camping Can Be Cool", appearing as a person with a deer head and leg. Based on the in-episode dialogue, it is hinted that he is the guardian of the National Forest. It is unknown if he is a mutant or he became a deer-man to survive since he said, " Just like mother said she loved me and not to follow her back to the city".
He hates Mordecai, Rigby, Eileen, and Margaret because they violated the law to not trespass into the forest. Margaret was the first one to see him when she was out to collect wood. He chased the four who tried to flee in Margaret's car, but was proven to be even faster than the car. He aimed an arrow at the wheel of the car and the four came out of the car and saw a park ranger coming and begged for help. Before, he could kill them with arrows, he is killed after he is run over by the Park Ranger, causing a "deer in the headlights" scenario (even though he is part-deer and part-man).
After he was dead, the park ranger called the taxidermist and said that they should "put some clothes on the humany parts". He also represents a Native American, which is comparable in real life since real Natives live in preserves and parks as well and they both believe that all parts of the hunted should be used so that nothing is wasted.
Stag-Man was resurrected by Garrett Bobby Ferguson Jr. in "Exit 9B" but was sent back to Hell after Thomas signed the document that made the park a historical landmark.
- It is shown that he knows Mordecai and Rigby before Margaret and Eileen tagged along shown in the past time in the episode "Bad Kiss"
- He could have been born after a woman mated with a stag, which is likely.
- He is voiced by Robert Englund, best known for playing as Freddy Krueger in the Nightmare on Elm Street films. The deer man could be the mythical creature The Wendigo,a monstrous creature that transformed from a human. He is similar and/or possibly a parody of the villain "Kraven the Hunter" from the Spiderman comics.
