Helluva Afterlife by Hollianna
Fandoms: Helluva Boss (Web Series), Hazbin Hotel (Cartoon), Disgaea (Video Games)
19 Oct 2025

Summary
Armageddon is fast approaching as the fragile truce between Heaven and Hell begins to break. At the same time, various characters from all walks of life (alive or undead) find themselves defying the destinies they once thought was set in stone, leading to unexpected alliances, rivalries, romances, and moments of introspection as two worlds in one — tough-as-nails I.M.P and quirky Hazbin Hotel — embark on an endless journey of defiance amidst the chaos of a rapidly-changing afterlife. Just because one is dead, doesn't mean their story is over. And just because you're a demon, doesn't make you automatically evil.
(In other words, the biggest What-If Helluva Boss/Hazbin Hotel crossover fanfic you'll find anywhere!)

Summary
"You passed your interview!"
"How quaint." Alastor clicked his tongue. "I believe there were other steps you missed."
The devil waved a hand. "What questions would I bother with? Availability? Past experience? Should I give you a written test for why you want this position?"
Alastor leveled him a flat stare.
or
Alastor made a reckless decision to summon a demon from his mother’s old book of suspicious rituals as a means to get vicious vengeance. He didn't know he would summon the King of Hell himself. After dying, falling to Hell, and catching Lucifer's eye, Alastor finds himself spending his afterlife essentially being a secretary to the King of Hell and occasionally nannying a naive Princess of Hell. Alastor is trying to fulfill his contract, but for some unholy reason, her father keeps trying to figure Alastor out

Summary
"People often say, 'Believe in fate.' But Alastor always calls it the stupidest thing to believe in."
Before the infamous Hazbin Hotel, in a Hell where destiny mattered more than choices, Vox chased ambition, and Alastor chased amusement. What slipped through their grasp was far greater than either intended; the silence became the loudest thing left between them.

Summary
Charlie Morningstar left her home to follow her dream to open a new establishment where sinners could be redeemed, the Happy Hotel.
And yet, not even she knew that sometimes chasing a rainbow is like throwing a rock in a pond: it causes ripples enough to cause a domino effect through all nine rings of Hell, disturbing the fragile peace that came with the realm of darkness. Even with her good intentions, she’s unknowingly dragging all known realms into the grim unknown, for she is quickly lured into an age-old war with each soul she tries to save.
As Hotel continues to exist, all eyes are looking at her now, even those who are beyond everything that exists... not all of them will follow her pipe dream. If anything, they are more than ready to destroy it as she finds herself learning about her true purpose. Will Charlie succeed, becoming as Lucifera II Morningstar: The Savior of the Damned... or end up becoming an instrument of destruction for an inevitable future?
Until then... both the Devil and the Root of All Evil shall await their White Rider's destiny...

Summary
In the human year 1945, Charlie Morningstar flees her parents’ fighting into the cold fog of a wintery Pentagram City. Freezing, hungry, and alone, Charlie happens upon Rosie. The sinner, known throughout Hell as The Radio Demon, takes pity on the wayward princess and offers her tea and a warm bed.
Charlie’s fate changes direction as Rosie and Alastor step in as parental figures as Lucifer and Lilith deal with personal problems and Heaven’’s attempts to interfere with Hell’s direction.
A rigid and fanatical Sera is on a crusade to quash hope throughout Hell, and has set her sights on Lilith, but her anger, fear and hatred harm more than just the Morningstars as Emily and Vaggie question her methods.
Alone, and at the mercy of Alastor and Rosie, Charlie starts down a darker path, but can an angel, a sinner and a demon bring her back from the cliff’s edge?
Or has her mind already been turned away from the ideas of hope and redemption?

Summary
As an angel, made for God, I was told I'd do all these wonderful things and I was chosen for greatness. But now, I don't think God can believe those words. I have done whatever I can, but maybe I just wasn't created with the abilities to do what I was supposed to. All that's left to do is ask myself, what does greatness entail at this point?

Summary
“Good evening, I’m Jett Jawline with Triple-Seven News and we’re here tonight with the hero of the hour, the Angel of Pentagram City, Exorcist Vaggie! Now Vaggie, before the break we touched on your role during the Extermination Day Disaster, do you think you could explain to the audience just how you saved so many angels from the clutches of of the Princess of Hell?”
After a group of overly ambitious exorcists pursue a trophy kill and accidentally inspire a bloody revolt against Heaven, peace between both realms teeters on a razor’s edge. To make matters worse, the only powers-that-be even remotely interested in ensuring said peace lasts are hopelessly naive and without any real influence in their respective kingdoms. Tasked with defending Heaven’s new diplomatic mission from the very angry and well-armed residents of Pentagram City, and doubting this assignment is really the reward Adam made it out to be, Vaggie has a front row seat to more political intrigue than she ever asked for or wanted. What’s a disillusioned Exorcist-turned-security-guard to do?
