Alastor/History

Past
Alastor is a former radio host and serial killer hailing from,.

Born approximately around the turn of the century, Alastor lived in the, having witnessed the. He was close friends with Mimzy, being a regular at the jazz club she worked at. He would get drunk and still be able to dance with her. Alastor apparently spent his whole life thinking that the reason why he never fell in love was because he hasn't found "the right one", not even considering that he was aro-ace, partly because the term didn't exist at the time.

After he killed his murder victims, he would bury their bodies on a deer hunting ground. Sometime in 1933, while burying the body of one of his victims, he was shot and killed after being mistaken for a deer by a hunter. This is why his demon form shares many characteristics with that of a deer.

When Alastor arrived in Hell, he was originally seen as another sinner which no one paid much attention to. However, he possessed unimaginable raw power, which was never before seen in a human soul. He quickly toppled Overlords who had been dominant for centuries and then broadcasted this carnage on the radio for everyone in Hell in anonymity to hear. Eventually, he revealed himself as the culprit behind the incidents, which other denizens would begin referring to Alastor as "The Radio Demon", despite the lazy sounding alias. He eventually reunited with Mimzy.

At an unknown point of time, Husk, an Overlord at the time, lost everything to gambling and made a deal for ownership of his soul with Alastor.

At an unknown point of time, Alastor came under the ownership of another demon, being on their "leash", which he keeps secret from everyone else except for Husk.

At an unknown point of time, Vox had offered Alastor to join his team, which he declined. At some point the two Overlords began to see each other as hated rivals.

Seven years prior to the series, Alastor fought and almost beat Vox. Soon after, Alastor left Pentagram City for seven years.

"A Day In The After Life" comic
Alastor is taking a stroll through Pentagram City, prompting several demons cower and hide in fear as he walks along. He sits and reads a newspaper while enjoying a cup of coffee at a café.

Sometime later, Alastor strolls through Cannibal Town, where a group of cannibal ladies devouring a demon swoon over him. He bids them good morning and asks them to say hello to Rosie for him.

He arrives at a window full of televisions advertising Vox's products. Realizing that Alastor is watching the advertisements, Vox hijacks the TV signal and projects his face on the TV monitor Alastor is watching. Alastor merely shrugs it off and calls him a show-off before leaving, however, when far away from him, Alastor begins to curse at Vox, which ends when he stops by a newly opened butchers shop.

After visiting the butcher shop to procure some venison, Alastor overhears the owner trying to attack another patron. He quickly returns and tears apart the butcher, leaving after taking some meat for himself with his prior order.

Hazbin Hotel pilot
After several decades of "lacking inspiration" and feeling rather aimless, Alastor happens to come to the window of Radio Hacks and watches Charlie's performance about the Happy Hotel.

Later, Alastor arrives at the Hotel and offers to help in her efforts, but rather so he could watch sinners try and fail to better themselves for amusement as he finds the idea of a rehabilitated demon absurd yet entertaining. Upon his offer of helping being accepted, he summons Niffty and Husk as employees for the hotel.

After the hotel door is destroyed and he hears a commotion outside, Alastor looks out to see Sir Pentious arrive who tries to intimidate them. Alastor uses his powers to summon tentacles through a portal that destroys Sir Pentious' ship. Afterwards, Alastor leads the way back to the hotel and remarks that this endeavor was going to be the "start of some real changes" then alters the Happy Hotel sign to instead say "Hazbin Hotel".

"Overture"
Alastor showed Charlie and Vaggie the commercial he made, which the two hated because it made the hotel look terrible. He tells them that he hasn't be active for a while and he could have advertised the Hazbin Hotel with his radio show, but Charlie insisted on using the television. He quickly shot down Angel's idea of making a porn with the two having sex with each other as the commercial.

Seeing Vaggie frustrated with how producing the new commercial is going bust, he offered to help with only one condition: this will be the last time he will be involved with T.V, the medium he hates. She agrees to this and he summoned a film crew. While filming, he looked away from the camera. Afterwards, he was able to get air time for the commercial by pulling some strings and some limbs.

"Radio Killed the Video Star"
While drinking coffee on the balcony, Sir Pentious tried to pick a fight with him again. Alastor asked him who he is, before swiftly defeating him again, sending Pentious away in a fiery green explosion when the latter ripped his coat, seemingly unaware a VoxTek drone was spying on him. He then departed for the tailor to get his coat fixed, leaving some of his shadow creatures to fix the wall that Pentious blew up.

After leaving the tailor, he witnessed Vox performing Stayed Gone and left to go to his radio station so he could put Vox in his place. He hijacked the song by pointing out Vox would be nothing without the other Vees. Vox got so upset that he glitched out and caused a blackout across Pentagram City. Alastor, going into his full demon form, remarks to Vox that he is “gonna make him wish that he’d stayed gone”, before cutting Vox’s broadcast.

Alastor was later reintroduced to Sir Pentious by Charlie, remarking that he definitely remembers Pentious now since he ripped his coat. Pentious, at the urging of Charlie, delivered an apology to Alastor and returned the piece of fabric that he ripped off his coat. Alastor remarked that “not many people have been able to take even this much off him”, and that it must have meant quite a lot to Pentious, before burning the fabric piece.

Later, after Charlie, Vaggie, Angel and Pentious went to bed, Alastor emerged from the shadows and picked up the V-Watch that Pentious left behind. Turning it on, he tells Vox that he was gonna have to try harder if he wanted to get him, before crushing the watch, leaving Vox screaming in anger.

"Scrambled Eggs"
Alastor was in his bedroom dining on a deer for breakfast when Vaggie ordered him to dispose of the Egg Boiz. While on his way to an Overload meeting, the Egg Boiz were annoying him with questions. He later ran into Zestial and the two engaged in light conversation while walking with each other to the meeting. He leaves the Egg Boiz in charge of guarding the front door, not knowing that one of them, Frank, had stowed away in the elevator.

During the meeting, when Carmilla Carmine noticed that he was there, Alastor simply remarked that he was sure that they’ve all been wondering where he had been for seven years, only to look offended when Carmilla said that no one was wondering, but welcome back anyway. When Velvette showed up and revealed the head of a dead Exorcist, he remarked that it looked tasty, going so far as to poke it with his finger and then taste it. Once the meeting ended, he noticed Carmilla, her daughters and Zestial go into a nearby room to talk. Spotting Frank, he orders him to follow them.

When Frank returned, Alastor was waiting for him. Upon hearing that it was Carmilla who killed the Exorcist, he warns the Egg Boi to never tell anyone else this information.

When the loan shark pursuing Mimsy attacked, he proceeded to slaughter them and asked mimzy to leave.

Hello Rosie!

He reveals that exorcist can be killed and takes to see Rosie, a fellow overlord to enlist help from the cannibals. During the song Alastor tells Rosie that he is aware of Charlie's true power and think of guiding her to be on the winning side.

He confronted Adam when the later destroyed his shield. He put up a good fight but Adam destroyed his staff and critically injures him, forcing the overlord to flee.

After the battle he returned to his now destroyed broadcast station. He lamented on how he narrowly escaped death, while wondering if there is a loophole to escape his deal. Alastor later returned to the freshly rebuild hotel fully recovered.
