On the planet Htrae, Bizarro Junior was tinkering with his father's Duplicator Ray and fired it out into outer space. The ray struck Mister Mxyzptlk and created a Bizarro duplicate of him named Kltpzyxm (Mxyzptlk spelled backwards). Kltpzyxm came to Htrae and used his powers to create order by fixing things up - a serious crime on Htrae. Bizarro No. 1 tried to bring Kltpzyxm to justice by forcing him to say his name forwards, but Kltpzyxm refused to fall for the trick, but instead turned himself in willingly.
