Master of Heroes is a crossover fanfiction by ThatOnePsycho (author of The Bloodstained Hero), between My Hero Academia and Fate/Grand Order. Also found on AO3 and FF.Net.

After saving the world twice over and defeating four Evils of Mankind, Izuku Midoriya finally returns home. What lies ahead for the Master of Heroes?

Due to the nature of the thread on Spacebattles, with the author answering questions and releasing additional content, this page may contain spoilers or unknown information for readers who have only checked it out on other sites.

Master of Heroes contains the following tropes:

  • Adaptational Badass: Heavily downplayed, however Izuku has gained several magical powers from his time with Chaldea. He's still nowhere near the rest of his class-to-be, however he isn't totally helpless either.
  • Adapted Out: It was confirmed that the recent addition of the Cast from Lifespan nature of One For All for wielders who already had Quirks is not in effect here.
  • All There in the Script: The actual meat of the story itself is told through the main chapters and flashback interludes, but the readers who don't go through the rest of the Spacebattles thread are missing out on several bits of world-building, extrapolation on Izuku's thoughts, explanations about his magecraft and skills, clarification about divergences from the Grand Order storyline, and answers from the author about the story and the characters.

  • An Arm and a Leg: Downplayed, however during the Shinjuku Singularity, Izuku's knee was completely shattered in an impact with Hessian Lobo, and was never healed correctly. Even with a cane, he can barely walk anymore.
  • Blow You Away: Izuku has an elemental affinity for air, which is explicitly stated to be better than his skill with fire (which amounts to little more than generating sparks).
  • Break the Cutie: Let's just say dealing with the Incineration of Humanity and the Invasion of the Alien God has left Izuku in a very bitter condition.
  • Broke Your Arm Punching Out Cthulhu: Izuku absolutely demolished himself over the course of completing Grand Order's plot, to the point of completely shattering one of his knees in an impact with Hessian Lobo, which never healed correctly. It's made clear he can barely walk even with a cane.

  • Cane Fu: Izuku has used a cane since Shinjuku, which he also used to club Beryl to death for all his actions before and during the Lostbelts, which ended up destroying the cane. It's confirmed that Holmes taught him how to do so, and taught him Baritsu as well.
  • Chick Magnet: Like Ritsuka Fujimura, Izuku has become the love interest of many Servants. Included among these are Mash, Hassan of Serenity, Okita (both versions), Anastasia, Jeanne Alter, Gray, and more. Caenis has called him a "harem king" due to this, although Da Vinci has told her not to say it in front of Izuku, lest he melt down completely. (It's mentioned that it was Blackbeard who first stuck him with this label.)
  • Even the Loving Hero Has Hated Ones: Izuku is still an All-Loving Hero, but he well and truly hates several servants (Kiara is the most noted one, but Columbus is also up there) and makes a point of incinerating them whenever they are summoned. Kiara is the one exception, since she can use Indepedent Manifestation to return to being Beast III-R and thus he has to keep her summoned to prevent this. Beryl is also in the hated category, and Izuku made his death extra painful because of this.
  • Everyone Has Standards:
    • Izuku may be an All-Loving Hero, but he outright despises Kiara and only maintains her summoning because it prevents her from using her Independent Manifestation skill to return to being Beast III-R. It's confirmed that he also straight-up incinerates several Servants (including Columbus) as soon as they're summoned for various reasons as well.
    • Izuku also personally killed Beryl to avenge Wodime and, more generally, to punish him for all the hell he caused. Afterwards, Izuku's only regret is in how brutal he had been in killing Beryl, not the actual killing itself.
  • Godzilla Threshold: It's implied that Izuku had made an agreement with Gilgamesh, never to use a Command Spell on the latter for any reason at all. How do we know this? Izuku commands the King of Heroes to unleash Ea via a Command Spell for the first and last time during the final battle with Beast VII, because the walking apocalypse is a big enough threat to justify said Noble Phantasm's use.
  • The Hero: Exaggerated with Izuku – his Origin literally is "Hero", and he so heavily defines himself as a hero that he has a nervous breakdown over things that would suggest he can't be a hero.
  • Heroic Self-Deprecation: The author has confirmed that this Izuku suffers from Impostor Syndrome to a truly horrific degree, utterly incapable of seeing himself as anything other than a fraud who's been riding the coattails of far greater people than himself. It's for this same reason that he also can't fathom the concept that any of the female Servants (or Mash) could possibly find him desirable.
  • Is This a Joke?: Inko gets notably angry when Dantes and Artoria Alter tell her they're Izuku's friends, since they're only showing up now for reasons she can't comprehend. She calms slightly after Artoria bluntly tells Ms. Midoriya that Izuku is alive and they are taking her to see him.
  • Locked Out of the Loop: Izuku has never told all but a select few of his Servants that he was bullied by Bakugou back in his homeworld. Justified because some of them are Heroic Spirits of Vengeance and consider him to be their Morality Chain, so there's a good chance Bakugou wouldn't survive their wrath.
  • Marry Them All: Apparently Anastasia has plans to this effect for Izuku, according to a side comment by Tomoe Gozen. Considering the tags on FFN, there's a fair chance she will succeed.
  • My God, What Have I Done?: How Izuku feels about himself after he killed Beryl. It's less that he did the deed, and more on how brutal and full of malice he was when he killed him.
    • Kintoki mentions during a conversation with Izuku that if Raikou were to be summoned into any Class other than Berserker, she would be appropriately horrified by some of the things her Berserker-self has done (such as trying to attack Inko, simply for being Izuku's mother).
  • No Kill Like Overkill: Izuku ended up beating Beryl's head in until it was essentially pulped during their final confrontation. Understandable, given that killing Beryl in the first place involved subjecting him to a Rasputinian Death to overwhelm his regeneration.
  • Offscreen Moment of Awesome: By the time of the main story, Izuku has already destroyed all of the Lostbelts, killed Beryl, and vanquished the Alien God. We only see snippets of those battles, but it's very clear that said battles were amazing.
  • Oh, Crap!: Inko gets understandably uncomfortable on two occasions: when she learns that Jack the Ripper sees Izuku as her mother, and when she learns that Kiyohime has feelings for her son.
  • OOC Is Serious Business:
    • Word of God has confirmed fan speculation that if Class 1-A and U.A.'s staff ever found out about the events of Grand Order, they would immediately reassure Izuku that he is a hero – even Bakugo and Aizawa would get in on it.
    • Izuku also has/had an extreme hatred of Beryl for all the crap the latter pulled across the events of Cosmos in the Lostbelt, as well as whatever Beryl did to Mash. It was such that he personally beat Beryl to death with his cane, and while Izuku does regret how brutal he was in offing Beryl, he does not regret killing said Crypter.
  • Parental Substitute: It's made clear Doctor Roman was this for Izuku during his time in Chaldea, acting as a mix of replacement father and older brother figure for him. He did not take Roman's death well, to the point that he has personal hatred towards Goetia for surviving and invalidating Roman's sacrifice.
  • Playing with Fire: Izuku has limited skill with fire-related magecraft - and we do mean limited, as he all he can manage so far is to create sparks (with some implication that this is all he will ever be able to do in that field). He can create flames, but this is a result of him being creative with his fire and air magic - he transmutates the air into flammable gas ala Roy Mustang, then uses the sparks to ignite the gas. It's been noted that he normally uses a lighter to get the spark, though.
  • Promotion to Parent: Several of the younger Servants, most notably Jack the Ripper and Jeanne Alter Santa Lily, consider Izuku to be their parent-figure. He's done his best to roll with it. Inko is shown to be rather exasperated by all of this.
  • Rasputinian Death: Beryl Gut did not go down easy: Izuku mentions that he shot him, then stabbed him when he kept coming, his cane was broken clubbing him with it, and he eventually went hand to hand and beat Beryl to death and continued well after his head was caved in. Izuku is understandably upset by how far he went. Ironically, this is tame compared to what Beryl suffers in canon in the Sixth Lostbelt.
  • Spared by the Adaptation: After some consideration, the author had Pepe end up alive but in a coma in the aftermath of the events of Cosmos in the Lostbelt. Pepe canonically dies in Lostbelt 6 in a Heroic Sacrifice to kill Beryl.
  • Timey-Wimey Ball: The events of Fate/Grand Order take place over about 3-4 years, however only six months have passed in Izuku's home universe since he left. Dantes notes that this will be a problem.
  • Too Spicy for Yog-Sothoth: A massively downplayed example, however Word of God has confirmed fan speculation that even Midnight would squirm in discomfort if/when she were to ever meet Kiara, simply due how absurdly lustful the latter is.
  • Tragic Keepsake: Izuku has a Zippo lighter that he uses to generate sparks for his fire magecraft. It was a gift from Doctor Roman, so he treasures it, to the point of going back to his room when Chaldea was invaded at the start of the Lostbelt Saga just to retrieve it.
  • Transmutation: Izuku has an affinity for this, such that his flame generation is actually closer to Roy Mustang's style of Alchemy: he transmutes the air into flammable materials and then ignites them using either a lighter or sparks.
  • A True Hero: Word of God confirms that Izuku's view of a true hero has shifted from All Might over to Mash, due to the latter taking the Ars Amadel Saolomonis for Izuku so that her Master could have the chance to defeat Goetia, and overall showing feats of heroism that eclipse All Might by several orders of magnitude. This also extends to Dr. Roman, for roughly the same reasons, though pushed Up to Eleven since the latter Ret-Goned himself to put Goetia in the ground.
  • Values Dissonance: This hasn't been brought up in the story, but according to the Author, due to the nature of Quirk-based society, Lostbelt 3, the Sublime Immortal Nation, would actually be more horrifying for the people of MHA-Earth In-Universe.For context 
  • What Does She See in Him?: Izuku has this toward himself, as due to his extreme Imposter Syndrome, he can't fathom why a girl would ever be interested in him.
  • What You Are in the Dark: An extremely exaggerated example, but readers have noted that Izuku's completion of the entire plot of Fate/Grand Order is this, as he has literally saved the world twice and fought four different Evils capable of annihilating all of mankind, yet no-one will ever be aware of this.
  • Word of God: The author adds to the story and answers questions about the characters and the background of the story in-between posting chapters, which some readers might have missed if they didn't read it through Spacebattles. Or read this page.
  • Worthy Opponent: Wodime's earnest and heartfelt goal of helping Humanity has earned Izuku's respect, and is partly why he hated Beryl so much when he betrayed him in cold blood.
  • Yandere: Due to the nature of her EX-Rank Mad Enhancement, Raikou takes her status as Izuku's "mother" very seriously, to where outright tries to attack Inko once the latter appears onboard the Storm Border. Thankfully, Inko never realizes that she was the target of said aggression, as a timely intervention by Gawain makes it look like she was targeting him instead.note
