Doomstone is a place which first appears in "The Bad Guy". At first, it seemed as if the entire planet was made of criminals when Wander and Sylvia arrived. However, after the chase around the city, it turned out the entire population were fakes and phonies who just came there because they thought it would make them seem tougher. They then all become friends and give up their evil ways. Two main residents are Badlands Dan and Papa Doom. They also rename the city to "Congenial Rock".
