Duela Dent

Duela Dent is a fictional character in the DC Universe. She is a former member of both the Teen Titans and Titans East. Introduced under the alias of Joker's Daughter, she has also used the aliases "Catgirl", "Scarecrone", "Riddler's Daughter", "Penguin's Daughter", "Card Queen", and "Harlequin".

Pre-Crisis
Duela Dent first appeared as Joker's Daughter in the Batman Family series of comic books. She gained the attention of Robin, as she later claimed to be the daughter of Catwoman, Scarecrow, Riddler, and Penguin. She deduced Robin's identity and he revealed that she was Duela Dent, Two-Face 's daughter.

Duela claimed she wanted to join the Teen Titans to atone for her father's crimes. Not everyone was in favor of this idea. In Teen Titans #48 she changed her identity to Harlequin. As Harlequin, Duela utilized gimmicks such as smoke-inducing powder puffs and bullet-firing lipstick.

After the Teen Titans comic books were canceled, she popped up in the Batman titles, calling herself Card Queen while infiltrating a criminal organization called MAZE.

Duela's last pre-Crisis appearance is in Tales Of The Teen Titans #50, as a guest at Donna Troy 's wedding where she appears to be a middle age matron. Dick Grayson notes that he'd finally realized she was too old to be Two-Face's daughter, which she agrees with, but disappears before he can take the matter further.

Post-Crisis
Delusional and schizophrenic, the mysterious Harlequin has been in and out of mental institutions for several years. An acrobat who possesses numerous "clown-motif" gadgets, she calls herself Duela Dent (while her true identity remains unknown).

Her first significant Post-Crisis appearance was in the Team Titans comic book, as a patient in a mental hospital. The writers of the title originally planned to reveal that Harlequin was a time-traveling member of the Team Titans driven insane by her warping experience.

However, due to the cancellation of the series, plans for her to return were aborted. The final issue of Team Titans solicited a non-existent story for Team Titans #25, and provided a commentary on the title's cancellation. In the solicitation, Duela steals a reality-altering device and shifts New York City into the late 1970s.
