This article is about Death's son. If you're looking for the park worker, see Thomas.

Thomas is a minor character in Regular Show. He made his debut in the Season 3 episode "Dead at Eight".


In the episode "Dead at Eight", Mordecai and Rigby are forced to babysit him, in exchange for Death saving Muscle Man's life. He is shown to be obnoxious and rude, disobeying Mordecai and Rigby, constantly refusing to go to bed. After shamelessly tricking Mordecai and Rigby into releasing a Soul-Sucking Death Worm, he begins to laugh as it nearly kills the duo. At the end of the episode, a chandelier falls on his head, knocking him out, causing his parents to think he was asleep.


Thomas is a short, demon-like figure who is over 300 years old, pretending to be 8 months. He wears periwinkle footie pajamas and has sharp fangs. He also has creamish-yellow eyes.
