Debbie Stevens, played by Brooke Theiss, is a character in the film A Nightmare on Elm Street 4: The Dream Master.
Debbie, the last of Alice Johnson's friends after the others are killed by Freddy Krueger, has a deep-rooted fear of insects. Knowing that Debbie will be Freddy's next target, Alice tries to save her; however, Freddy traps Alice in a time loop without her knowledge.
By the time Alice can escape, she is too late to reach Debbie before Freddy attacks her; he kills Debbie by painfully transforming her into a cockroach, trapping her in a Roach Motel and crushing her.
