Fans of Vivienne Medrano’s Hellaverse have waited a long time for Helluva Boss and Hazbin Hotel to properly share the screen. In an exclusive interview with Polygon published on September 13, 2026, the creator known as Vivziepop explained how that meeting will unfold. The short version: a few visual winks in the first half of Helluva Boss season 3, something bigger in the second half, and a full-scale crossover that is still only a hope.
How the shows ended up under one roof
The groundwork was laid in April 2025, when news broke that Helluva Boss would join Hazbin Hotel on Prime Video. Amazon’s announcement video made several promises:
- Medrano’s animation studio Spindlehorse keeps full creative control.
- New Helluva Boss episodes will eventually be released free on YouTube, where the show’s first two seasons already live.
- For the first time, the two series will cross over in some way, beyond simply being set in the same universe.
Part 1 of the two-part third season premieres on Prime Video on October 14, 2026. According to Popverse, it contains seven episodes, with the remaining eight arriving in 2027, and each new episode reaches YouTube about a month after its Prime Video debut.
Why the crossover starts small
Timing is the reason. Medrano told Polygon that part 1 was written before the Amazon deal was finalized, so the story was never built around the sister show. “It does start this season, [but] more of the exciting crossover potential is in the second half,” she said. Where the animators could lean in was the visuals: “We were able to go, ‘Oh, we can actually maybe see Hazbin characters.’ So you might see some things.” In practice, that means Easter eggs rather than plot twists.
The second half, written after the Amazon pickup, goes a step further, though Medrano still calls it comparatively small. She promised “a little bit more than a cameo” in what she calls season 3.2, and declined to say who might turn up. Her own preference is clear: “I’m a big fan of the bigger, full-on, focused crossover. So fingers crossed we’ll get to do that at some point.”
Fifteen episodes, split down the middle
The two-part release came down to scale. “The season is 15 episodes, which to anyone who’s used to how animation is produced nowadays, is a lot,” Medrano said, calling it “basically two seasons worth of episodes.” Rather than make viewers wait until 2027 for the whole run, she chose to get the first half out as soon as possible.
That choice had a side effect. The last episode of part 1 was never written as a finale, but the team gave it “a little bit of finesse” to give it more of a finale feel. Medrano described it as a thematically big episode and a clear midpoint for the season. It is not a cliffhanger, but it is “definitely not the end of the story.”
