The Bizarro League, also known as the Bizarro Justice League, are the Bizarro version of the Justice League.

The Bizarro World was destroyed in Crisis on Infinite Earths along with the Bizarro League.

When the Joker got 99% of Mister Mxyzptlk's power as part of the Emperor Joker storyline, he recreated the Bizarro League and the Bizarro World. When the imp got his powers back, he kept the new "Bizarro World".

Bizarro gained "Bizarro Vision" (allowing him to make imperfect clones) under a blue sun. Bizarro planned to destroy the Bizarro World to be the reverse of Superman (because Superman would never destroy a planet). So the Bizarro-Lex Luthor led a revolt and unleashed the juggernaut Bizarro-Doomsday. The BL stopped the juggernaut by dropping a steel drum on him. However Bizarro ended up destroying the planet after all.

Bizarro Justice League has not been a contender in any CBUB matches.
