The Bizarro World (also known as htraE, which is "Earth" spelled backwards) is a fictional planet appearing in American comic books published by DC comics. Introduced in the early 1960s, htraE is a cube-shaped planet, home to Bizarro and companions, all of whom were initially Bizarro versions of Superman, Lois Lane and their children and, later, other Bizarros including Batzarro, the World's Worst Detective. In popular culture "Bizarro World" has come to mean a situation or setting which is weirdly inverted or opposite to expectations.
In the Bizarro world of "htraE" ("Earth" spelled backwards), society is ruled by the Bizarro Code which states "Us do opposite of all Earthly things! Us hate beauty! Us love ugliness! Is big crime to make anything perfect on Bizarro World!" In one episode, for example, a salesman is doing a brisk trade selling Bizarro bonds: "Guaranteed to lose money for you". Later, the mayor appoints Bizarro No. 1 to investigate a crime, "Because you are stupider than the entire Bizarro police force put together". This is intended and taken as a great compliment.
Originally a normal planet, htraE is now cube-shaped. This is due to the intervention of Superman, who - after being convicted of doing something perfect on htraE, which would normally be a capital offense - pointed out that the planet was shaped like a normal spheroid and agreed to cube it if his sentence were commuted.
