Alastor VS Denji (Devilish Pets)

 

First we see Denji being into Makima's Office being at the Public Safety Devil Hunter job while Makima says.

Makima: Hello, Denji!

Denji: H-Hello, Mrs. Makima!

Denji replies nervously while Makima then answers.

Makima: You'll see Denji, I've heard news about something, something that has got me intrigued for days. Radio is one of the most known artifacts to get information, and I heard there was a charming Man who was the Star of his own Radio Show, he had the charm, the smile, the aspiration. From what I heard his name was Alastor!

Denji: Uh but why is this guy evil exactly? I don't see anything wrong with that...

Makima: Let me keep going on and finish, turns out rumors said he did hide something dark under that charming smile... In the nights he had a double life, he was a bad person during his life, being a Serial Killer and responsible of several Deaths and it's theorized he also was a cannibal. But unfortunately for him, he died in 1930 being shot in the head, confused by a deer. 

Denji: Damn, he sounds really Fucked Up! But Man Are you real? He died confused by a deer, that sounds so ridiculous!

Makima: Yeah but don't let that confuse you, he may have died on a frankly unusual way, but he was very clever on his ways to kill people as these things im telling you seem to be mere rumors... However, what we know is he is dead, and if he is truly evil I am assuming he could be some powerful Radio Devil, it could be really useful if you found out if he is really real and brought him down, because if he is real he could be a potential threat to our job, Denji and we don't want anything like that, and if you hunt down this Radio Devil... I promise I will do anything you want!

Denji now has a surprised stare on his eyes Denji in his mind says "Wow, is this real?! Anything I Want?! I must be dreaming!".

Denji: Wait... Anything I Want?!

Makima: Yes, you heard me... I won't say it twice.

Denji then smiles getting courage anf says.

Denji: Alright, i'll get into killing this Radio Devil for you Mrs. Makima don't be worried!

Denji said running away out of the office in his way to find out the Radio Demon, Denji then said.

Denji: Damn this is the best day ever, If I kill that Radio Devil I can finally touch Mrs. Makima's Gorgeous Boobs! I couldn't ask for anything else! This is a Dream that will end becoming true!

Denji said however a random portal appears and traps Denji teleporting him into the Hell of Hazbin Hotel.

Denji: Wow, what the hell?! Where even Am I?!

Denji said as all he could see is a red moon with a pentagram in the sky and Heaven and a red sky and many buildings and demons around swearing and fighting each other violently with knives and stuff.

Denji: Wow, dude this must be Hell! This is just as scary as I thought it would be!

Denji said looking surprised of Hell but he walks around and finds out the Hazbin Hotel.

Denji: Uh what? Is this like a Hotel in the middle of... Hell? But why?! And where is this Radio Devil I am searching?!

We see Alastor was walking back to the Hotel while he was humming a Jazzy Song, Alastor finds out Denji and heard the words Radio Devil calling up his interest, so Alastor teleports as a shadow in front of Him.

Alastor: Hello!

Denji: Uh, who are you?! Would this be the Radio Devil Makima told me about?! But he doesn't look like a serious menace, why is Makima so afraid of this guy?

Alastor: Oh you got it close boy, but I am not a Radio Devil! Let me introduce myself! My name is Alastor, and I am the Radio Demon! And this Makima your talking about is afraid of me? Well, you sure got my mood even better today thank you for that!

Denji: The hell do you mean mood?! Your like always with that suspicious smile!

Alastor: Ahahahaa! You should smile too more often, your never fully dressed without one! But also you really think I ain't a serious menace? Well, If I wanted to hurt you... I would have done so already!

Alastor said with a demonic tone changing his eyes to look like radio dials with a wide grin twisting his neck with the environment glitching with the sound of radio frequencies while Denji looks at Alastor with a bit of surprise but Alastor then goes back to normal stopping trying to be scary as he said.

Alastor: But well boy, anyways you got me quite intrigued! What was your sin to end being here, and are you searching nonsensical redemption on the Hazbin Hotel, or are you one of Vox's newest goons? I reeaallyyy want to know what your up to, Boy!

Denji: Well you don't scare me, And You shouldn't be glad that Mrs. Makima fears you, My Heart is only for her! And If I kill you there, I can get anything I want from her! So your not gonna live for long, Stupid Radio Demon!

Alastor: HAHAHAHAHHAHA! Oh, What a Little Fantasy! Do you think you can beat me?! I am the Strongest Sinner in Hell! I am sorry creep but your not gonna get anything from this Makima any time, Plus only a Demon can be the one pulling the strings and what are you gonna do?! Your just a Boy and I am a literal Demon! You stand no chance here!

Denji: Oh I am not any Boy, I am actually a Chainsaw Man!... AND I AM GONNA SLICE YOU TO PIECES!!!

Denji said pulling on his chest chord now with Chainsaws Sproutting on his arms and head splattering blood in the ground as he turns into his Chainsaw Man form.

Alastor: Oh so your a Demon Hybrid! Well, how interesting... Oh, This Will Be Fun!!!

Alastor said while summoning his staff and sproutting tendrils from his back as they are both ready to fight. 

                                                                 FIGHT!!!

Alastor targets several Tendrils Towards Denji but Denji swings his chainsaws towards the Tendrils slicing them down to bits sproutting black blood out of them, Denji then tries to slash Alastor but he swiftly manages to dodge a lot of Denji's swings until he summons a green portal on the ground making Denji fall until a Tendril manages to wrap around his legs trapping Denji and before Denji would try to slice it down he would be sent to fly by Alastor against a building, destroying it, Denji recovers from the debris as Denji then says.

Denji: Your weird tentacles aren't gonna be enough to get pass me Sawing your Toothy Grin to bits!

Alastor: And you think I should fear you?! HA! Your just a boy trying to act like a Demon! Your never gonna get that Lady's focus I must say!

Denji: SHUT UP!!!

Denji rushes angrily towards Alastor but Alastor would dodge the slash but Denji would recklessly end sawing the door of the Hotel in half accidentally sawing down many sinners in there making them yell in pain splattering them to blood scaring many other Hell residents and making them run away.

Alastor: Oh I haven't had this kind of fun for years! 

Charlie however realizes of the Chainsaw Man and yells scared.

Charlie: AHHH!!! OH MY GOD, WHAT HAPPENED HERE?!

Denji: I AM TRYING TO KILL THE RADIO DEMON, HE IS JUST A SADISTIC ASSHOLE AND THIS WAS ALL A N ACCIDENT, I AM REALLY SORRY FOR THIS!!!

Charlie: You must be the most cruel Overlord in All of Hell, and Alastor? Why do you wanna kill him?!

Denji: I WAS SENT HERE BY MRS. MAKIMA TO KILL HIM!!! AND I WON'T GIVE UP TILL HE IS DEAD! HE ISN'T ANY GOOD AND IS AN EVIL THAT MUST BE KILLED!!!

Charlie: But Alastor... He is my friend and he has defended this Hotel, he may be redeemed! I don't think he deserves to be killed before he can have a second chance in life!

Denji stayed thoughtful for a second, he remembered the time he was poor and had life harsh but then met Makima and had a second chance in life, Denji didn't know what to answer about this but he knew Charlie was right. If he deserved a second chance in life, maybe Alastor would too.

Denji: Oh My God, what Am I thinking?! I am such an Idiot, your right I got a second chance in life, maybe he like everyone deserves one too!

Charlie: I-I am actually glad you can understand, thank you for being so comprehensible!

Charlie said happy but everyone else finds out what happened.

Angel Dust: Oh My God! Charlie, stay away of him!

Husker: Charlie don't get close to this guy don't you see the corpses around him he is evil!

Vaggi: CHARLIE! YOU MONSTER STAY AWAY OF HER!!!

Denji: But I am not a Monster! I just commited a mistake and this was an accident I can explain!

Husker: You can't really explain this! Just look at that your definitely responsible of this!

Vaggi: And get away of this Hotel before I end with your lfie, NOW!

Alastor: HAHAHAHA! OH THIS IS VERY ENTERTAINING!!!

Alastor said taking advantage of the drama and uses his tendrils again to make Denji get wrapped on them again surprising him and Alastor sends Denji to fly away knocking him against a car as the rest was surprised.

Charlie: Alastor, Wait!

Vagggi: Leave him, Charlie it's too dangerous!

Husk: Alastor...? What the fuck is happening?

Angel Dust: Eh I don't know must be Strawberry Pimp got into something!

The Hotel people said thinking about the problem. Alastor then said.

Alastor: Well your quite more entertaining than I expected, boy I must admit but let me get this clear... Your Not One to Talk with Charlie Morningstar!

Denji: AAAHHH!!! YOU MONSTER!!! YOU DON'T CARE ABOUT INNOCENT LIVES DYING?! IT WOULDN'T HAVE HAPPENED IF YOU STOOD STILL AND TOOK THE ATTACK INSTEAD, I BET YOU DON'T EVEN CARE ABOUT THAT GIRL CHARLIE, DO YOU?! YOU DIDN'T CARE AND ALL YOU ARE I JUST SMILING WATVHING PEOPLE DIE, THEN WHY DO YOU EVEN CARE ABOUT CHARLIE?! THAT'S JUST NONSENSE!!! I AM GONNA SAW YOU INTO BITS AND STOP YOUR STUPID SHOW OF SUFFERING YOU MONSTER!!!

Alastor: Hmm... Well, anything I have to think about Charlie isn't for you to know I think she is very entertaining and a very inspiring person but your certainly not one to speak to her! And I can't tolerate people like you showing disrespect to fair people... I find it distasteful... LIKE BAD MEAT!!! YOUR SCREAMS OF AGONY WILL BE SATISFYING FOR MY BROADCAST!!!

Alastor said summoning an Explosion bigger than city blocks which sends Denji to fly away, incinerating his shirt, Denji however  shoots chains that catch Alastor off guard as Denji then attaches him to him and uses one of his Chainsaws to slice Alastor's chest ripping off the green stitches on his chest as Alastor with his strength closes his fist and rips off the chain and holds his chest in pain while Denji drinks his blood.

Denji: Thanks for the free heal dumbass!

Denji said drinking Alastor's blood but Alastor summons his Shadowy Voodoo IMP Denji tries to slice them down but they are sneaky moving around Denji and attacking him with his claws but Denji angrily slashes them down but Alastor quickly hits Denji with his claws, sending Denji to fly against a wall shattering it. Alastor then wraps his Tendrils on Denji's body with green electricity making him yell in pain.

Alastor: Is this shocking enough for you?!

His Staff emits a public's laugh but Denji spins his chainsaws fast speeds again to slash off the Tendril as Denji said.

Denji: NOT ENOUGH!!! AND I WILL SLASH YOU TO SHREDS, HAHAHAHA!!!

Denji uses his Chainsaws again swinging them to Alastor trying to slash him again but Alastor disappears from Denji's sight with his teleportation amongst the shadows and wraps his tendrils around trucks but Denji reacts in time and slashes them in half.

Denji: TELL ME DO YOU KNOW WHAT IT'S LIKE TO FONDLE ON SOME TITTIES, RADIO DEMON?!

Denji said as Alastor said.

Alastor: Another disrespecful and unclassy comment of those and I am Broadcasting your screams for a century!

Alastor said while wrapping his tendrils around two light bulbs propelling himself towards Denji as the two charges towards each other, Alastor slashing into Denji's chest and Denji slashing further into Alastor's chest sending each other to fly bleeding towards buildings. Both get up bleedy holding their chests in pain. Alastor summons a forcefield bigger than the Hazbin Hotel as Denji uses his Chainsaws trying to slash it down slowly shattering it until Denji uses his head's chainsaw yelling slowly shattering it down but Alastor then transforms into his Wendigo form his back expanding, his neck grotesquely becoming larger, stitches seen on his mouth with an evil grin and an X forming on his forehead with antlers growing with an unsettling sound as Alastor laughs evilly.

Alastor: HAHAHAHAHAHHAHAHAHAHAHAHA!!! NOW YOUR GONNA WISH THAT I'D STAYED GONE!!!

Alastor grows giant, swatting Denji away like a fly against a building, rushing there laughing dragging Denji down against buildings, and then saying.

Alastor: I AM GONNA DEVOUR YOU WHOLE!!!!

Alastor then eats Denji while laughing evilly thinking he has one but near instantly chainsaws sound as Alastor cuts through Alastor's stomach making blood rain down on the ground as Denji is now all covered by blood drinking some of it laughing maniacally as Alastor reverts down to normal holding his stomach in pain.

Denji: RAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAGHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH!!!!

Denji said now turning into the Hero of Hell roaring in Rage as Denji says.

Denji: AFTER I AM DONE WITH YOU, YOU WILL BE FOOD FOR THE CHAINSAW MAN, I WILL EAT YOU AND YOU'LL END CEASING TO EXIST, AND NOBODY WILL EVER REMEMBER YOU!!!

Alastor quickly summons more Shadowy Voodoos but Denji slices them down like Butter quickly, then he summons Niffty and Husker while Niffty says.

Niffty: Alastor is in trouble! I am taking down this Bad Boy!

Husk: What the fuck did you get on this time, Alastor?!

Niffty rushes to Denji who angrily tries to slash her down but she dodges with sneaky moves and stabs Denji around making him yell in pain while Husk starts to shoot explosive kinetically charged cards to Denji while flying blasting him a lot both hurting and keeping Denji busy until Denji gets mad and slashes Niffty a lot into a blood mist and then slashes Husker in his skull and part of his chest slicing off his wings making Husker yell in pain as Denji slashes both a lot drinking their blood to heal, Alastor now gets greatly annoyed and summons a lot of Tendrils with electric green sparks but Denji crazily starts to slice them down 

Denji said nearly as if he was insane, Alastor sees how his henchmen are now heavily wounded covered in blood and growls angrily even with his usual smile and shoots the tendrils towards Denji who in rage starts to slash them down to bits and rushes towads Alastor and angrily starts to slash his upper body a lot and part of his arms dropping a lot of blood drinking it to recover the more he recovers the fastest he slashes Alastor until Alastor falls down next to a wall, holding his upper body in pain due to the excessive blood lost and Alastor even coughs up some blood, Alastor tries to use his staff but Denji slashes it, breaking it on half, and Denji then says.

Denji: IT'S NUTS OR NOTHING NOW, DIPSHIT!!!!

Alastor: W-Wait...!

Denji was gonna slash down Alastor to nothing but he stops, he was curius on what Alastor was trying to do.

Alastor: I... I have a Proposition for You!

Alastor said with green stitches covering most of his upper body and his arms regenerating and using the stitches to protect his wounds he couldn't heal quickly as he was doing this painfully as Denji stayed confused.

Denji: A proposition...?

Alastor: I am willing to do... A little deal with you... You'll see, So I see this Makima lady is quite very enticing for you... I can give you quite anything you desire from her, comfort, affection, fun, acknowledgment... Quite anything enticing for your liking, all you gotta do is just accept!

Alastor said with his usual smile, Denji was very thoughtful, as he knew Alastor was very evil but this was quite an offer he wouldn't reject.

Denji: Does it include anything? Like a good life, and finally being able to fondle Mrs. Makima's boobs?

Alastor stayed silent for a second, he knew what Denji said was quite disgusting and something a young boy of his age would say but then Alastor decides to answer.

Alastor: Oh yes, anything that you wish for, so what do you say, Chainsaw Devil? Is it a deal then?

Alastor said showing his hand while Denji without a second thought said.

Denji: Deal!

Both shakes hands but Alastor would laugh evilly for Denji's confusion.

Denji: What?!

Alastor: HAHA... HAHAHAHHAA.... HAHAHAHAHAHAHAHAHHAHAHAHAHAHAHAHA!!!!!

Denji said confused realizing now his soul belongs to Alastor.

Denji: What?! WHAT DID YOU DO TO ME?! THE DEAL WAS HAVING ANYTHING ENTICING FOR MY LIFE AND FONDLING MRS. MAKIMA'S BOOBS, NOT THIS!!!

Alastor: HAAHAHAHAHAHAHAHA!!! OH WHAT A FUCKING CREEP, YOU REALLY THOUGHT I WOULD GIVE YOU AAAALL OF THAT?! PATHETIC, THERE ARE NO FRIENDS IN HELL, BOY AND YOU JUST FELL INTO WHAT US DEMONS IN HELL DO BETTER QUITE AN AMATHEUR!!! NOW YOUR SOUL BELONGS TO ME!!!

Alastor said as he sees how Pochita now with free control tries to slash Alastor but Alastor teleports amongst the shadows behind Pochita and swingsh his finger saying confidently.

Alastor: Ah, ah, ah!!!

Alastor does a blast which obliterates Pochita's body as Hero of Hell to pieces sending Pochita in his dog form to fly into Alastor's hand as Alastor said.

Alastor: Oh I hate Dogs, so I rather find eating you something distasteful even for me but if its to make this Boy suffer, it makes it definitely More FUN!

Alastor said eating Pochita in front of Denji as Denji now cries.

Denji: P-POCHITA!!! NO!!! WHAT DID YOU DO?!?! HE WAS MY ONLY FRIEND AND NOW HE DOESN'T EXIST ANYMORE!!! THIS IS ALL MY FAULT, I REALLY ONLY THINK USING MY DICK!!! I FAILED IN MY LIFE, I FAILED FOR MRS. MAKIMA... I EVEN FAILED POCHITA!!! I AM A LOSER, I DON'T DESERVE TO LIVE!!!

Alastor: Well, I am gonna tell you a few words! This Makima your talking about never really loved you! She most likely ooonly wanted to control you as a whole using you like a piece of a chess game and wanted to only possess that power from your demon pet! Quite cruel, but also quite useful I most admit! That Makima Lady is quite clever at it, but now you are no use for her in this state anymore!

Denji: N-NO, YOU AREN'T BEING SERIOUS!!! PLEASE TELL ME IT'S NOT TRUE!!!! PLEASEEE!!! YOU HAVE ANY IDEA OF HOW MUCH I'VE WAITED LOVE, APPROVAL AND AN ACTUAL GOOD LIFE?! SO MANY GIRLS TRY TO KILL ME, FIND CHAINSAW MAN'S HEART... BUT WHAT ABOUT DENJJ'S HEART?!

Alastor: Hmmm, Well, that was quite philosophical I must admit. But don't worry cuz I will put an end to your suffering!

Denji was just shocked, his face fueled with tears and feeling worried, however he decided to accept fate, he knew he couldn't do anything and the only useful thing rn would be acceptation, Alastoe BFRs his soul to his radio dimension turning it into radio waves as Denji yells in agony as Alastor destroys his soul killing him as he broadcasts Denji's yells across hell in his radio tower now.

Alastor: HELLO, AGAIN AUDIENCE TIME TO INTRODUCE MYSELF AS THE EQUAL OPPORTUNITY KILLER... ALASTOR!!! AND THIS IS A REMINDER TO ALL OF HELL.... NEVER MESS WITH THE RADIO DEMON, HAHAHAHAHAHHAHAHA... HAHAHAHAHAHA... HAHAHAHAHAHAHAHAHAHHAAAHAHAH!!!! Now, Stayed tuned, folks!

                                                           K.O!

THE WINNER IS... ALASTOR!!!
