Actress Kathleen Robertson, who plays the adult Azkadellia, deliberately portrayed the character as a quiet menace, self-restrained rather than gregarious: "It's a very daunting prospect when you're asked to play one of the most iconic film villainesses in history. As opposed to playing Azkadellia archetypal and loud, I played her internal and psychological. She's narcissistic, she has every personality disorder that you can figure." Producer Michael O'Connor commented that "Our Wicked Witch is a little bit different than that in the book, but we think she's a touch more evil and diabolical." He also remarked that Kathleen Robertson brought "the deliciousness of evil to the role." Robertson, production designer Michael Joy, and actor Neal McDonough (who plays Wyatt Cain) have all remarked that Azkadellia's personality informed the scenic design of the O.Z. and the look and feel of her minions, from the costuming of Azkadellia and her Longcoats to the appearance of the mobats. According to Joy, "Azkadellia is in love with power—drugged by power. Everything is in the image of that power." He describes the costumes of the Longcoats as "stormtrooper-meets-leather bar" and the interior decor of Azkadellia's palace as "futuristic for 1930s' fascist realist".
