The Disgruntled Postman is an insane mailman and a foe of the Justice Friends.

The Disgruntled Postman was then sent to jail. He was voiced by Tom Kenny.


The Disgruntled Postman is very similar in appearance to the Joker wearing a postman's uniform. His skin is white; his hair green; and his lips are red. He wears a postman's uniform consisting of a light blue long-sleeved collared shirt, a black tie, blue shorts, black knee length socks, black shoes, and a blue postman's hat.

  • The Disgruntled Postman is resembled to The Joker from Batman: The Animated Series and all of the DC Animated Universe during the early 90s to the mid-2000s.
  • He is also based on the infamous string of mass murders that occurred during the 80s and 90s which were committed by "disgruntled postal workers".
