Mad Mansion was seen in "Mad Mod", where the Titans woke up after being captured by Mad Mod. Throughout the episode the Titans had attempted to escape the mansion, but only succeeded after Robin saw through the hoax and destroyed Mad Mod's machine, disabling all of the illusions.
With Mad Mod as its owner, Mad Mansion is a giant mansion with hypnotizing walls to hypnotize Mad Mod's "guests." The mansion is a giant maze, changing over and over, with Mad Mod being the only one who knows how to get around. Mad Mansion is proved to be full of illusions and its actual location is an oil rig off the coast of Jump City. Mad Mansion is a playable arena in the Teen Titans video game.
