Darkest Hero is a crossover between My Hero Academia, Hellaverse, and Hellraiser by Bfghunter2. It can be accessed on AO3 here
, Fanfiction Dot Net here and on Wattpad there.
What happens when Izuku took Bakugo's advice and took a swan dive off the roof? As they say, suicide is a sin, so how does hell cope with a pure soul, and how will the heroes cope with an innocent demon?
This fanfic provides examples of:
- Abusive Parents: Hisashi treated his wife and son like crap after Izuku was diagnosed as Quirkless, resulting in Inko killing him.
- Adaptational Badass:
- Izuku becomes a Cenobite after death with the ability to manipulate green fire.
- Momo becomes a Cenobite after she accidentally opened the Lament Configuration in her possession and survived the Cenobite attack that killed her parents.
- Kyoka can utilize magic as part of her demigod heritage.
- Inko, as it turns out, is actually Leviathan, the patron deity and ruler of the Cenobites.
- Adaptational Early Appearance:
- Tokoyami shows up at the Hazbin Hotel far before his introduction as a member of Class 1-A.
- Eri shows up way before the Shie Hasshiki arc even begins.
- Adaptational Jerkass:
- Hisashi here is a lousy dad who is implied to have abused Inko before she killed him.
- Bakugo is a lot more loutish and unpleasant around other people, to the point that no one can stand to be around him.
- Downplayed with Uraraka, who, aside from having a grudge against Bakugo for scarring her eye, is still the Nice Girl she was in canon.
- Adaptation Relationship Overhaul:
- Kirishima and Mina are close friends who regard themselves as siblings in all but blood rather than a couple.
- Eraserhead and Ms. Joke are an actual couple rather than co-workers.
- Adaptational Sexuality:
- Todoroki all but confirms that he's gay in chapter 39, much to Tsuyu's disappointment.
- Alastor in canonically aroace, while here he dated a woman in the past and is pursuing a relationship with Inko.
- Nemuri in cannon mainly acted like a dominatrix just as part of her Midnight persona and was actually a motherly individual who loved caring for children. Here? Overhearing a conversation about where Izuku, Charlie, and Vaggie are gonna sleep while topside inspires her to make a deal with Lucifer and Lilith, of all demons, for a demonic threesome. Don't worry, they don't ask for her soul, just some shampoo from her company.
- Uraraka and Jirou are a couple in this fic while in canon, they were just classmates and friends.
- Adaptation Species Change:
- Izuku and Momo become Cenobites, the former due to his heritage as Leviathan's son and the latter from opening her Lament Configuration.
- Inko is changed from a human into the patron deity of the Cenobites, with her mortal identity simply being the latest in a long line of incarnations of Leviathan.
- Kirishima becomes a golem demon after Mineta murders him.
- Mina is a succubus since her mom is a succubus queen.
- According to Alastor, he transformed Ibara into a demon after she tried preaching to a figure heavily implied to be Moonfish.
- Eri and Toga become Cenobites thanks to Inko's magic.
- Kyoka Jiro is revealed to be a minor goddess in chapter 30.
- Overhaul gets turned into a vulture demon after Inko kills him.
- Age Lift: Most of the UA crew are at the 18-20 mark for age, with UA made into a university.
- All Animals Are Dogs: More like undead monster in this case, but the USJ Nomu (aka Mr. Squishy) behaves like an oversized dog after Eri makes it her pet.
- Asshole Victim:
- Mineta is put through no short amount of torture after he ends up in Hell, but considering how he murdered innocent people and was an unrepentant pervert, no one really cares.
- Radoshi Dando is one after his true(?) identity as Snot Rocket is revealed by Rikiya.
- Berserk Button: For Vaggie, mentioning her Dark and Troubled Past as a sex worker is a surefire way to earn a punch to the face, as one cop finds out.
- Beware the Nice Ones: Seriously, Inko more than qualifies for this given her status as the incarnation of Leviathan and the fact that before that, it was implied that she killed Hisashi after she couldn't stand his abuse.
- Bring Me My Brown Pants: Blitzo admitted to crapping himself after coming face-to-face with The Slayer.
- Bullying a Dragon:
- Overhaul immediately threatens to kill Inko and Eri after he's brought into the Hazbin Hotel. Inko proceeds to show the recently-transformed yakuza why it's a bad idea to threaten the Goddess of Flesh, Hunger, and Desire along with her loved ones by dragging him into the basement of the hotel to torture him.
- Katie Killjoy makes the same mistake by attempting to accost Inko right after she tried to do the same with Charlie, Vaggie, and Izuku, which results in Inko calling in one of her Cenobites to keep her "contained" for a little bit. Knowing what Cenobites get up to, Katie is not in for a good time.
- Clingy Jealous Girl: Charlie and Vaggie are initially unhappy about Ibara claiming Izuku as hers before they gradually warm up to Ibara thanks to Ibara's kindness and willingness to share Izuku with Charlie and Vaggie.
- Cold Ham: Tokoyami is just as grandiose and edgy as his canon counterpart.
- Composite Character:
- Nedzu is the reincarnation of Bill Cypher.
- Inko and Leviathan are one and the same.
- Creepy Child: Eri's a little too enthusiastic when it comes to torture, though that comes with the territory of being raised by the patron deity of the Cenobites.

- Azazel from Helltaker makes an appearance as the angel who accidentally sent Izuku to hell after he died.
- Goose from Captain Marvel (2019) shows up as Bakugo's pet cat.
- Purple Guy and the Fazbear animatronics show up as residents of Hell.
- Apparently, the events of Supernatural take place in the same universe as this fic.
- Dark and Troubled Past: Alastor was once in a relationship with a African-American woman named Francine back when he was a human until the Ku Klux Klan killed her after Jeeper showed up. He then became a wendigo after he had to eat the dead bodies left behind after Jeeper's appearance.
- Dark Is Not Evil: Although Izuku, Momo, and the Hazbin Hotel crew are demons (Cenobites in Izuku and Momo's case), none of them have any inclination towards villainy.
- Death by Adaptation:
- Very much Implied in the case of Hisashi Midoriya, with Inko telling Izuku that Hisashi's off "working overseas".

- Did You Just Romance Cthulhu?: How one can see Hisashi marrying Inko as after it is revealed that she's Leviathan
- The Dreaded:
- Naturally enough, the Doom Slayer for demons. When encountering I.M.P., they were shaking like leaves at the sight of him.
- According to Millie, even Lucifer, the top dog in Hell, is hesitant to deal with Cenobites.
- Driven to Suicide: Izuku falling for Bakugo's suicide-baiting taunt and diving off a building is what kicks off the story.
- Everyone Has Standards:
- Mitsuki is absolutely pissed at Bakugo suicide-baiting Izuku once she's informed of what happened to him and chews out him out for such a horrible act.
- Alastor, despite being a Serial Killer in life, draws the line at hurting kids, which is why he hates child killers like Freddy Krueger, Chucky, and Jack Frost.
- The Cenobites unnerve everyone thanks to their incredibly creepy looks and propensity for extreme torture.
- While IMP and Angel Dust are hardened demon criminals, child abuse is a no-go in their books, and they make sure to bring in Overhaul so he can suffer after they find out he abused Eri.
- As it turns out, not even Hell likes Nazi swastikas, which is shown when Izuku and co. see a set of swastikas on a wall that were defaced with graffiti.
- Eri's enthusiasm for torturing Overhaul creeps out Uraraka and the others when they end up in Hell since she's still a child despite her conversion into a Cenobite.
- Nifty is sick and tired of the radio constantly playing "Inside of Every Demon is a Rainbow" in the Hazbin Hotel and goes to town on the radio when Alastor triggers it with his entrance.
- Bakugo may be a total asshole, but not even he wants to destroy Eri's innocence explaining what "fuck" and "bitch" mean after the recently-turned-into-a-demon Overhaul calls Inko a "fucking bitch" to her face.
- According to Yui, Monoma claims that he only swaps out his undies once a week, grossing out Kirishima with the sheer unhygienic implications of such a statement.
- Everyone's Baby Sister: Eri is this for Izuku and company given her young age and relative innocence compared to everyone else.
- Expy: Izuku's demonic form is stated by the author to resemble Ghost Rider, except with green flames and horns.
- The Friend Nobody Likes:
- For a given definition of "friend", Bakugo most certainly qualifies with his boorishness and arrogance.
- All of Class 1-B barely tolerate Monoma thanks to his overinflated ego, unpleasant behavior, and the fact that he's deliberately teaching Pony swear words, meaning that they're more than happy to put him through "second-year training" in the form of subjecting him to pranks every week.
- Fluffy the Terrible: Eri names the USJ Nomu the pet name of "Mr. Squishy", nevermind that the Nomu is an undead monstrosity made up of dead people.
- "Freaky Friday" Flip: Chapter 47. After her experimental telepathy device malfunctions, Mei accidentally transplants everyone into different bodies before she manages to repair it and get everything back to normal.
- From Bad to Worse: Shigaraki opening the Lament Configuration he had in his possession during the USJ causes things to go to hell in a handbasket very quickly by summoning the Cenobites, forcing everyone to band together to hold off the Cenobites until Inko arrives to tell the Cenobites off.
- Happily Adopted: Himiko and Eri certainly are happier as Inko's adopted daughters than when they were in their previous families, that's for sure.
- Hermaphrodite: Toru turns out to be one in chapter 28, much to the consternation of Class 1-A.
- I Need a Freaking Drink: Izuku, his girlfriends, Toga, and Mina chug the vodka Aizawa gifted them as respite from all the paperwork the Hazbin Hotel staff have been dealing with since the Icon of Sin's rampage and the general chaos from that incident.
- It Amused Me: Alastor and Nedzu have this as their modus operandi; if there's anything that can make their life more interesting, they'll do it.
- It's All About Me: Bakugo's inflated ego is somehow worse than it is compared to canon, most notably yelling at Eraserhead's mom that "he is the hype" when he meets her in Hell.
- Karmic Butt-Monkey:
- Bakugou goes through a constant barrage of humiliating situations both in and out of Hell and Earth, but the fact that he's a massive dick and was the one who suicide-baited Izuku only makes his constant humiliation hilarious.
- Mineta is put through a lot of terrifying and humiliating situations in Hell, but considering how he murdered his parents and friends for trying to stop his perverted antics, he has all of it coming for him.
- Lethal Chef:
- Ibara's cooking is really, really bad, to the point that she accidentally summoned Legion one time before she and the others beat him back.
- Todoroki is no better than Ibara is, if Bakugo's reaction is of any indication.
- Like Brother and Sister: Tokoyami and Dark Shadow are practically siblings by how close their relationship is.
- Locked Out of the Loop: God may be the boss of Heaven, but it doesn't mean he can receive updates on what's going on there 24/7. Azazel has to inform him of what CHERUB is up to when he approves of Charlie's redemption efforts.
- The Lost Lenore: Francine is this for Alastor given how the KKK murdered her.
- Mugging the Monster: A human thug attempts to rob I.M.P. with just a baseball bat. Blitzo just shoots him and remarks how stupid it is to try to rob someone that is armed.
- Noodle Incident:
- Azazel's a Persona Non Grata in Shoel Nagarx't for asking way too many questions for its residents to stand.
- Apparently, Dark Shadow took control of Tokoyami one time and annoyed the Great Old Ones with her antics at some point. They also got lost in Pentagram City and ended up in the city's porn museum after they took a wrong turn while looking for ice cream.
- Official Couple:
- Tokoyami and Reiko have plenty of Ship Tease moments with each other and the author has confirmed them as a canonical pairing for the story.
- Miss Joke and Eraserhead are also confirmed to be an official pairing in the story.
- Obstructive Bureaucrat: The HPSC practically embodies this trope just like they do in canon, what with their endless regs and constant nagging.
- Pay Evil unto Evil: Eri is given free reign to torture Overhaul after Angel Dust brings him over to the hotel. Considering all the torture he put Eri through, it's nothing short of Laser-Guided Karma for the former yakuza boss.
