Ilonka, played by Elena Verdugo, is a character in the film House of Frankenstein.
Ilonka is rescued by Dr. Gustav Niemann and Daniel after Lawrence Talbot turned into the Wolf Man and wreaks havoc.
Daniel falls in love with her; it is unrequited, however, as Ilonka falls in love with Talbot. Daniel tells Ilonka that Talbot is a werewolf, but she is undeterred, and promises Talbot that she will help him. Events reach a crisis point when Niemann revives the monster and Talbot again turns into a werewolf. The werewolf attacks and fatally wounds Illonka, but she manages to shoot and kill Talbot with a silver bullet before she dies.
