The Stag is a character first seen in "No One Can Hear You," as the main antagonist of the episode. He abducts all the candy people and attempts to take their "sugar," but is kicked down a whirlpool in a sewer by Finn and Jake. He makes a cameo appearance in "Sons of Mars," where he is turned into a telescope by Magic Man. It is unknown if he got turned back.
- He oddly wears gloves that looks like hooves on his front legs which are actually arms and hands. This shows that he's not a deer, but a magical creature.
- He is identical to the stag man from Regular Show who is like a arch who tries to shoot Mordecai, Rigby, Margaret and Eileen.
