Alastor/History

Past
Born into a mixed-race Creole family approximately around the turn of the 20th century, Alastor lived in, , as a radio host and serial killer, and witnessed the.

He was close friends with Mimzy, being a regular at the jazz club she worked at, where he would get very drunk and still be able to dance with her. Because of the time period which had a lack of knowledge of different types of sexualities and romantic preferences, he spent his whole life believing he was straight instead of aromantic asexual, and thought that the reason why he never fell in love was because he hadn’t found "the right one".

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, being ignored by many. However, he soon demonstrated that he possessed unimaginable raw power, which had never been seen in a human soul before. He quickly toppled Overlords who had been dominant for centuries and then broadcasted this carnage on the radio for everyone in Hell to hear. Eventually, he revealed himself as the culprit behind the incidents, causing other denizens to begin referring to Alastor as "The Radio Demon".

At some point he reunited with Mimzy, who he helped whenever she got into trouble.

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 made a deal and came under the ownership of another demon, being on their "leash", which he keeps secret from everyone else, except 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 been 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 shoots down Angel's idea of making porn of 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 television, the medium he hates. She agrees to this and he summoned a film crew. While filming, he looked away from the camera out of spite. 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 tries to pick a fight with him again. Alastor not knowing who he was 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 and went to his radio station so he could put Vox in his place. He hijacked Vox's broadcast, 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 video feed.

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 Dust and Sir 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 corpse for breakfast when Vaggie ordered him to dispose of the Egg Boiz. While on his way to an Overlord 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 left 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, and 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 welcomed him 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.

Back at the Hotel, Vaggie comments that Alastor failed to get rid of the Egg Boiz and he responds that they were very useful before giving them back to Sir Pentious.

"Masquerade"
Alastor appears in a flashback as Husk revealed his past as an Overlord.

"Dad Beat Dad"
After Lucifer's arrival at the Hotel, the pair did not get along. Alastor and Lucifer got in an exchange of insults only to be interrupted by Mimzy.

Husk approached him in order to warn that Mimzy's arrival will bring problems. Alastor brushed it off until Husk reminded him of his own deal, angering Alastor to the point of threatening to torture Husk and broadcast his screams across Hell.

When the loan sharks pursuing Mimzy attacked, he proceeded to slaughter them and asked Mimzy to leave as she posed a danger to the Hotel.

"Hello Rosie!"
Following Charlie's disastrous visit to heaven, he paid Charlie a visit in her room. He proposed her a deal: grant him a favor in exchange of a critical information on exorcists, which she agrees to. He reveals that exorcist can be killed and takes her to see Rosie, a fellow overlord, to enlist help from the cannibals. He was confused when Rosie called him an "ace in the hole" since he doesn't know about asexuality. While at the pavilion, the two Overlords revealed that one cannibal, who even Rosie and Alastor think is a handful, will make things near impossible to succeed: Susan. Alastor uncharacteristically gave Charlie his microphone staff. During a song, Alastor tells Rosie that he is aware of Charlie's true power and thinks of guiding her to be on the winning side.

"The Show Must Go On"
A day before the extermination starts, Alastor observe the Hotel's resident banter while having a conversation with Niffty about how they grew attached to everyone. She places a crown made from dead bugs on his head and called him the King of Roaches.

When the angels attacked the next day, Alastor put up a shield around the Hotel. He confronted Adam when the latter destroyed his shield, and in the ensuing fight against Adam, Alastor is defeated; with his cane broken and being critically injured, the Overlord is forced to flee.

After the battle, he returned to his now destroyed broadcast station, having a nervous breakdown. He laments on how he narrowly escaped death, while wondering if there is a loophole to escape his deal. Alastor later returned to the freshly rebuilt Hotel fully recovered and is hugged by the gang.
