Being a lesbian and in a sense clownish this female Joker falls madly in love with the alternate version of Harley Quinn whose name is Hailey. Miss Steeplechase has been Hailey's idol since she was young and never felt this way for another human being, male or female.
She kills the alternate Dick Grayson which cause much grief in Batgirl's life. Batgirl is so saddened by this that she masquerades in the Robin costume. She even cuts her glamorous red hair to resemble his.
