Well, well, well. It seems that Cruella De Vil isn't just a furious fashionista.

On Sunday's spring premiere of Once Upon a Time, viewers were introduced to the maven of monochrome's magical power: the gift of persuasion over animals. All it takes is one breath (of halitosis? pheromones?) from Cruella (Victoria Smurfit), and the critter is hers to command.

But how far do her powers extend? Could she hold sway over fairy-tale creatures like unicorns? "We are actually going to test that theory — whether or not she can control magical creatures — in the second half of the season," co-creator Edward Kitsis tells TVGuide.com. Controlling magical creatures is only one step away from controlling magical beings that are part animal. If Cruella has this ability, then she could potentially have influence over her fellow Queens of Darkness Ursula (Merrin Dungey), who is part octopus, and Maleficent (Kristin Bauer Van Straten), who has the ability to take dragon form.

Whether or not Cruella would turn on her allies remains to be seen. But at least one resident of Storybrooke should be worried. Archie (Raphael Sbarge) owns a Dalmatian named Pongo, whom the EPs promise will make an appearance this season. "He will absolutely run into Cruella," Kitsis says. Gulp!

What do you think of Cruella's power? Will she turn on the other Queens of Darkness?
