A former child star named Mary Dahl has become bitter and insane after falling into obscurity and realizing she has a disorder that prevents her body from growing to adulthood, thus biologically cursed with literal eternal youth. She kidnaps her TV family, who all led more successful lives and careers than her, and holds them prisoner on an abandoned sound stage. While Robin works fast to free the actors from Baby-Doll’s explosive death-trap, Batman pursues the tiny fiend through a deadly carnival fun house.
Baby Doll, while appearing in two different Batman: The Animated Series episodes (“Baby Doll” and “Love is a Croc”) makes the cut because, amazingly, she’s never shown up anywhere else since. None of the movies, other cartoons or even the comics. For christ’s sake, the CONDIMENT KING made it into the comics! He even has his own Wikipedia entry! As a character, she’s workable, but as a murderous female Gary Coleman/Punky Brewster analogue she’s stuck is in that odd area of not being a cool enough or weird enough idea to crossover into other media. Fun fact: Paul Dini wrote “Baby Doll” and Steve Gerber (Yes, that Steve Gerber) wrote “Love is a Croc”. Additional fun fact: Both of these men have written other, better things!
AN OBSCURE BATMAN CHARACTER. EVERY SATURDAY. THAT’S THE HIVE OF SCUM PROMISE.
