Heck Hound is an evil demon dog who comes from the pits of heck and the arch nemesis of White Tiger. He is also being a villain to The Justice Friends sometimes. One of the episodes he appeared in was the episode "Can't Nap" Where he came into their house and Krunk was allergic to him.
- A very similar character also named "Heck Hound" appeared as a villain in the fellow Cartoon Network show 2 Stupid Dogs in a Secret Squirrel segment which Paul Rudish (writer of the Justice Friends) also worked on.
