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.[1] 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.
