For fans of Hazbin Hotel, the devil is in the details—literally. The Prime Video animated series, created by Vivienne Medrano, has built a Hell so richly layered that even the background art tells a story. Those scattered eyes, the lingering glances from the shadows, have long been a source of fan theories. Now, Medrano has finally shed some light on their meaning, and it all points to one character: Roo.
In an exclusive interview with Collider at FanX Salt Lake, Medrano revealed that Roo, a character fans have been eagerly awaiting, has been watching the entire series unfold from the very beginning. “The implication is that she kind of has seen everything this whole time,” Medrano explained. That revelation gives those eerie eyes a whole new significance—they’re not just set dressing; they’re Roo’s windows into the world of Charlie and her crew.
This puts Roo in a unique position when she finally steps into the spotlight. She already knows Charlie, Vaggie, Angel Dust, and the rest intimately, while they remain blissfully unaware of her existence. It’s a power dynamic that Medrano is clearly excited to explore. “She’s kind of been almost like the audience,” the creator said. “She’s kind of been observing the show.”
But don’t expect Roo to be a simple villain or a straightforward antagonist. Medrano was quick to caution that fans should prepare for a surprise. “When she eventually shows up, she’s probably not gonna be what people expect,” she teased. That’s because Roo isn’t a typical character at all. “She ultimately isn’t a real person; she’s like an entity,” Medrano explained, describing Roo as “an entity that doesn’t really have one identity.”
This shapeshifting, manipulative nature is something Medrano is having a blast with. She hinted that Roo’s ability to mask herself will play a big role in how she interacts with the world. It’s a concept that opens up endless possibilities for storytelling, and it’s clear Medrano has been thinking about this for a long time. “I conceptualized her a long time ago,” she said, and she’s eager for fans to finally meet her.
For those who’ve been rewatching Hazbin Hotel with a fine-tooth comb, this news is a goldmine. Those eyes in the background, the subtle hints in the animation—they’re all part of Roo’s presence. Medrano’s comments suggest that a rewatch might reveal more than just Easter eggs; it might offer a glimpse into Roo’s true nature.
While Medrano stopped short of revealing Roo’s identity or her exact role in the larger story, the implications are huge. An entity that has been watching everything, that knows how to manipulate and disguise itself, is a formidable force. It’s the kind of mystery that keeps fans theorizing, and Medrano is clearly enjoying the ride.
In the meantime, fans can catch up on Hazbin Hotel Seasons 1 and 2, now streaming on Prime Video. Season 3 has yet to receive a release date, but with revelations like this, the wait will be anything but quiet. For more from Medrano, check out the full interview with Collider below.
