Batwoman - real name Kathy Kane - will appear in 52, a year-long DC Comics publication that began this month. In her latest incarnation, she is a rich socialite who has a romantic history with another 52 character, ex-police detective Renee Montoya. 52 will be published in the UK as a graphic novel by Titan Books in 2007. The series is set in a world in which established superheroes like Batman, Superman and Wonder Woman no longer play a part.

The new-look Batwoman is just one of a wave of ethnically and sexually diverse characters entering the DC Comics universe. Others include Mexican teenager Blue Beetle - who replaces the character's previous white incarnation - and the Great Ten, a government-sponsored team of Chinese superheroes. Regular characters Firestorm and The Atom, meanwhile, have been reinvented as black and Asian heroes respectively. The characters are part of a wider effort to broaden the make-up of comic-book creations in line with society as a whole. Batwoman, who first appeared in July 1956, has not been seen since September 1979 when she was killed by the League of Assassins and the Bronze Tiger.
