A-G
- Abled in the Adaptation: In the comics, Arthur suffered from trigeminal neuralgia, which left half his face paralyzed. Here, he does not appear to be disabled.
- Actor Allusion: He quotes the Last Words of the eponymous character of Hamlet while confronting Marc in the tomb. Ethan Hawke played the prince himself in the film adaptation released in 2000.
- Adaptational Attractiveness: In the comics, Harrow had a Red Right Hand in the form of partial facial paralysis which kept the left side of his face locked in a perpetual scowl. Here, he seems completely abled.
- Adaptational Badass: The comics Harrow was a Dirty Coward who left his thralls to do the fighting while he fled from Moon Knight. In the series, Harrow shows Nerves of Steel when faced with danger, wields powerful magic, and is surprisingly competent in melee combat. Not to mention this version of the character was once a superhero himself.
- Adaptational Dumbass: While he is still by no means unintelligent, his comic counterpart's Nobel award-winning intelligence has been removed from this adaptation of the character. Tellingly, instead of Mad Science, he relies on the outside power of the goddess he worships and a wealth of loyal cultists to achieve his goals.
- Adaptational Dye-Job: He was an Evil Redhead in the comics, but has light brown hair in the show.
- Adaptational Hairstyle Change: In the comics, Harrow has a short, neat haircut that is connected to his beard, but has Barbarian Longhair and a clean-shaven face in the show.
- Adaptational Heroism: While he's still a villain here, he's a far cry from the Mad Scientist who targeted minority groups for scientific experimentation. Here, he's a Well-Intentioned Extremist who genuinely believes he's cleansing the world of evil, his cult actively encourages diversity among its members, and if his powers deem someone innocent, he truly is happy for the person and celebrates their goodness. Notably, while comic Harrow was inspired by the Nazis, this Harrow decries Hitler as a monster who could've been stopped had Ammit been loose.
- Adaptational Nice Guy: Arthur Harrow in the comics was a Mad Scientist inspired by the Nazis who tried to target certain minorities and lethally experiment on them. While he's still a villain here, Harrow is more of an Affably Evil Well-Intentioned Extremist who is the head of a Mystery Cult that wants to impose the will of Ammit on the world and is genuinely kind to his followers. Said cult also apparently recruits from all races, and is actively trying to promote diversity within the group as well (by, for starters, encouraging them to learn to speak at least three languages). That said, when the Scales of Justice tip the wrong way...
- Adaptation Personality Change: The Harrow of the comics was a sadistic Neo-Nazi who specifically targeted minorities out of racism. Here, he's an Affably Evil Well-Intentioned Extremist who actively encourages diversity amongst his cult and specifically cites Hitler as a monster that Ammit could have stopped.
- Affably Evil: Ruthless as he is, Harrow is quite cordial and polite, trying to reason with Steven several times before resorting to open violence. When his powers judge one of his followers "good" (well, good by his and Ammit's definition, anyway), he seems to genuinely praise the man and even hugs him. Episode 2 shows this perfectly, as he shows Steven the nice crime-free neighborhood his cult has made, seems to have a legitimate friendship with his followers, and treats Steven to lentil soup because he knows he's vegan. And then he talks about how his utopia will be built off of killing people for something they won't be guilty of until the future, including children.
- Dr. Harrow is also kind, gentle, legitimately wants to help Marc and the rest of the system, and cares for his staff just as Harrow does to his followers — though whether Dr. Harrow is a part of the afterlife or a manifestation of the system's mental illness remains unclear.
- Agony of the Feet: Subverted. Arthur puts broken glass in his sandals as part of a daily ritual, but is either so disciplined or so inured to pain that he shows no apparent discomfort from it. Then, in "Gods and Monsters", the 'Dr. Harrow' that Marc and Steven are conversing with in the asylum starts bleeding from his feet as both alters reject his diagnosis that the asylum is reality and the MCU is a delusional episode he's having. Dr. Harrow is noticeably unsettled that he's bleeding despite never having been harmed by the duo, which they mock him for, noting that he doesn't know as much as he'd like to believe before 'waking up' in the MCU reality.
- Animal Motifs: Crocodiles (which represent his goddess Ammit) surround him, with his scale tattoo, his staff being tipped by crocodile heads, and his leather shoes calling to mind crocodile hide.
- Animated Tattoo: On his right arm, he is shown to bear a strange tattoo of the Scales of Justice that shifts underneath his skin when he measures the purity of other people's souls, turning green when they are deemed "balanced", and red when they are not. When he tries to judge Steven, however, the scales shift back and forth wildly without deeming him good or evil.
- Anti-Villain: He genuinely wants to make the world a better place. Resorting to using a crocodile goddess' powers to kill bad guys preemptively, however, does make him very much in the wrong.
- Apologetic Attacker:
- He is apologetic towards both his elderly follower and the vagrant who stumbles across the scarab when he uses Ammit's power on them and judges them to be guilty.
- After fatally shooting Marc and Steven, he apologizes, albeit in a rather backhanded way.Harrow: I'm sorry it had to be this way, Marc Spector... Steven Grant... whoever else might be in there. Sometimes we need the cold light of death before we can see reality.
- Ascended Extra: Arthur only appeared in one issue of the Moon Knight comics, but becomes the main antagonist of the miniseries.
- The Atoner: Inverted, as it put him on a villainous path, but Arthur admits to an imprisoned Khonshu in episode 3 that he's genuinely ashamed at having enjoyed inflicting pain under the god of the moon's command, which is why he eventually left his service and began his strange broken glass ritual as a form of atonement for it. He admits to Ammit that his quest to free her was his attempt at penance to balance his scales. When Ammit says his scales still remain unbalanced, he's ready to die, but lucky for him she's just as Affably Evil and pragmatic as he is, because she believes an avatar who's unafraid to get their hands dirty is more useful than one that's morally balanced.
- Barbarian Longhair: Arthur Harrow has shoulder-length hair, which he wears loose. It looks much like David Koresh's, albeit not as curly. The barbarian part comes into full focus in "Gods and Monsters", when he proves to be ferocious in combat as he brawls with Marc, Steven, and Layla.
- Batman Gambit: He reveals the broad circumstances of Layla's father's death, implying that Marc was responsible, gambling that she'll confront Marc about it immediately and thus buy time for his forces to catch up with them. Sure enough, that's exactly what happens.
- Beware the Quiet Ones: Arthur is soft-spoken and speaks very concisely, but he's also a powerful magic wielder with the ability to kill someone in the blink of an eye if they're judged "evil". Episode 6 showcases that his staff isn't just a Classy Cane or a tool for worshipping Ammit, it's a powerful weapon that he's very good at using, and when he stops holding back and becomes Ammit's Avatar, he almost single-handedly thrashes Marc, Steven, and Layla (and keep in mind they are officially Khonshu and Taweret's avatars, respectively). It takes Jake, the most violent of the three alters, forcibly fronting to put a dent on him at all.
- Big Bad Duumvirate: He shares the role of the main villain with Ammit in Moon Knight, seeking to free the goddess completely of his own accord. While he presents himself as merely her Dragon, Harrow, as the apparent founder and leader of her disciples, is the key to her success; is Marc, Steven, and Layla's more personal enemy; and takes on the integral role of Ammit's avatar to see her judgement through. Without him, she would have been trapped forever in her ushabti, and just as much emphasis is placed on stopping him as it is stopping the goddess.
- Black Speech: Averted. He is able to invoke the power of Ammit with ominous sounding chants and invocations. It's actually Coptic, an ancient Egyptian tongue used almost exclusively in the modern era for sacred purposes as a liturgical language for the Coptic Orthodox and Catholic Churches.
- Blue-and-Orange Morality: What makes his brand of well-intentioned extremism unpredictable. His idea of what constitutes a "good" person is based on Ammit's skewed and nebulous definition.
- Celebrity Paradox: Batman has been referenced a number of times in the MCU. Ethan Hawke voiced Batman himself in Batwheels.
- Composite Character: While his name is taken from obscure Moon Knight villain Arthur Harrow, his characterization (and appearance) as a charismatic cult leader answering to a ruthless deity trying to bring twisted reckoning upon mankind's sins owes much more to the more mainstream Moon Knight villain called the Sun King. Aside from the name, the key difference between them is that Sun King is linked to Ra, while this version of Harrow works for Ammit. He's also a composite with Dr. Emmet, Moon Knight's psychiatrist who briefly served as an avatar of Ammit and was tied to Sun King's origin, something displayed prominently in the fourth and fifth episodes, which adapt the arc that introduced Dr. Emmet but with Harrow in her place.
- Copycat Mockery: When he sees Steven nervously looking over to listen to Khonshu, he asks Steven what Khonshu is saying. He then asks in a mockingly grandiose tone if he's talking about being "real justice", which briefly leaves Steven at a loss for words, as that was verbatim what Khonshu had just said.
- Create Your Own Villain: Harrow was once Khonshu's Avatar and a former Moon Knight, but grew weary of only punishing the guilty after harm was done and was ashamed of enjoying inflicting pain in Khonshu's service. While taunting the captive Khonshu, Harrow explicitly attributes his turn to Ammit's service to Khonshu.
- Curb-Stomp Battle: Although we don't get to see it onscreen, he thoroughly slaughters the Ennead council's avatars in battle when they attempt to stop him from resurrecting Ammit.
- Dark and Troubled Past: The references he makes to the time he served as Moon Knight paints it as a very bad period of his life, with mentions of Khonshu "breaking" him and his development of an enjoyment of delivering punishment, which he grew to resent himself for.
- Death Seeker: When it is revealed his own scales are imbalanced, he practically begs Ammit to punish his soul, even attempting to offer up potential Disciples of Ammit with balanced scales to take his place when she insists that he must be her avatar.
- Did You Just Flip Off Cthulhu?: He's completely irreverent towards Khonshu, dismissing his use of Dramatic Wind as childish Tantrum Throwing and telling Steven no other god respects him, all the while aware he's listening in on their conversation.
- Don't Make Me Destroy You:
- In "Summon the Suit", he threatens to unleash the power of Ammit held within his staff as he gives Steven a final chance to hand over the scarab. When Steven instead flees, he summons a jackal monster that proves to be a big enough threat to force him to give control of the body over to Marc to be able to defeat it.
- He makes a similar ultimatum to the Ennead council when they oppose him, making the offer to let them walk away if he is simply allowed to summon Ammit unchallenged. They refuse to obey, and he makes short work of them.Harrow: You're judges, not warriors. This doesn't have to happen.
- Dragon-in-Chief: It is only thanks to Harrow leading her disciples and agreeing to act as her avatar that Ammit is free to enact her judgement upon the world.
- Due to the Dead: Downplayed; Harrow doesn't bury or properly dispose of Marc and the system's body, but he has his followers at least drag the corpse out of the water, and Harrow leaves the scarab they had fought over with the body as a sign of respect.
- Establishing Character Moment: In his first scene, we see Harrow perform a type of meditation known as glass-walking, where he fills his shoes with broken glass and walks in them. He does this in private, without a single exclamation of pain, and wears shoes that completely obscure this to anyone else. This shows that despite his intensity and fanaticism in his beliefs, he is also completely genuine and does not desire to flaunt the things he does for his faith.
- Even Evil Has Standards: He makes it obvious in his speech to Steven in the museum that he considers the act of prejudice-fuelled genocide to be deplorable. He condemns figures such as Adolf Hitler and Pol Pot as being some of many that would have faced Ammit's wrath should she have been free.
- Evil Counterpart: To Marc. Both are or were at some point manipulated into serving Khonshu, and are consumed with self-loathing for their past mistakes to the point of viewing themselves as expendable. However, where Marc gradually starts to move past his self-hatred and his suicidal ideation, Harrow becomes so obsessed with atoning that he becomes a Knight Templar thanks to buying into Khonshu's ideology and taking it to extremes.
- Evil Gloating: He doesn't see it as evil, but he takes a moment to thank Khonshu for driving him into Ammit's service after the moon god is trapped in a statue.
- Evil Vegetarian: Like Steven Grant, Arthur doesn't like to eat meat, preferring to have lentil soup instead. Unlike Steven Grant, Arthur is the head of a cult and has no problems with killing those under Ammit's will.
- Exact Words: To avoid the wrath of the Ennead, he claims to simply be seeing the desert when questioned by them, which, while technically true, omits the actual reason he's in the desert. Since the gods don't know where Ammit's tomb is and Marc doesn't either, they can't disprove his claim.
- Face Death with Dignity: Subverted on two accounts. When Ammit tells Arthur that his scales are unbalanced, Harrow is fully prepared to die in order to serve his goddess, regardless of how much effort he and his followers put into bringing her back to life. However, Ammit still needs him to bring about her desire to eat all the unworthy souls of the world, and so does not kill Arthur. Later, when Khonshu orders Jake Lockley to kill him, Harrow realizes that he, unlike the other two alters, has no problem obeying the god, and Harrow can only get out a panicked "Wait!" before he's shot dead.
- Fallen Hero: He was once Khonshu's "fist of justice" towards the criminals of Earth, but eventually grew to find his available methods of punishment too lax, and dedicated himself to a Knight Templar role to see justice delivered in his own way, regardless of the cost.
- Footprints of Muck: In his final meeting with Dr. Harrow in his asylum, Marc notices him leaving faint bloody footprints through his shoes, which Harrow is quite shocked to see.
- Ghost Memory: Partially how his judgement powers work. When the ritual begins and Ammit's magic is used on someone's skin, memories they possess are transferred over to Harrow for him to witness. From these glimpses of the person, he decides with the guidance of his goddess what fate they are worthy of.
- Glowing Eyes of Doom: His eyes briefly glow purple when he becomes an avatar, and he subsequently Takes a Level in Badass before the final battle begins.
- Gory Discretion Shot: We don't see him as Jake Lockley delivers the Boom, Headshot! that kills him, with the camera cutting away to the outside of the car they're both seated inside.
H-N
- The Heavy: While Ammit is overall the main threat of Moon Knight (2022), Harrow ultimately does most of the heavy lifting on the show, even serving as the main obstacle for Marc and Steven in the Duat-psych ward. Justified, as Ammit was imprisoned up until the finale, with Harrow's main goal being to release her from her imprisonment.
- Hell Is That Noise: As mentioned, Harrow regularly performs glass-walking as a form of penance and religious mortification. While he makes no particular drama of it, the sound of crushed glass is prominent when he walks.
- Hero's Evil Predecessor: Episode 2 reveals he was Khonshu's avatar before Marc, but grew frustrated at only being able to punish evil after the fact. This led to his defection to the much more like-minded Ammit to be able to prevent evil before it could ever occur.
- Hoist by His Own Petard:
- Once he reaches Ammit's resting place and has no further use for the scarab, he leaves it behind... which allows Layla to subsequently pursue him with the discarded artifact.
- Accepting the status of avatar from Ammit ends up being the doom of his plans, as they allow Marc, Steven, and Layla to use his unwilling body as one of the needed avatars for Ammit's banishing ritual.
- Hypocrite: For all his claims that the "judgement" he doles out to others is justified and for the purpose of building a better world, episode 2 reveals how shallow his justifications are when he pulls a Life Drain on someone without actually doing the ceremony first, simply because they had gotten their hands on the scarab he needed. He does try to bargain with the man first, but jumps straight to killing him as soon as he gets close enough to do it.
- In Name Only: He practically has nothing in common with the comics version of the character. Justified, as Arthur Harrow only appeared in a single issue, so the writers didn't have much material to work with.
- Institutional Apparel: His outfit is changed into basic white scrubs when he becomes a committed patient of the Sienkiewicz Psychiatric Hospital.
- Internalized Categorism: Implied to be what's happening with Harrow, which also colors his own Knight Templar tendencies. Despite trying to espouse a Black-and-White Morality (then judging the rest of the world with Ammit's power), he confesses to the stone statuette of the imprisoned Khonshu that he in fact once enjoyed the kind of brutal violence and justice Khonshu asked of him. However, he seeks to move away from it, which likely also explains his turn to Ammit.
- Judge, Jury, and Executioner: He measures the worth of people's souls and doles out punishment, something condoned and encouraged by Ammit according to him. It's noteworthy that Egyptian mythology split this job between Anubis (who did the actual measuring) and Ammit (who ate them if he were guilty), but Harrow points out Ammit got tired of waiting and tried to punish sinners before they were judged.
- Karmic Death: He dies after Jake Lockley shoots him several times in the ending of "Gods and Monsters", no doubt payback for Harrow killing him and the system in the same manner in "The Tomb".
- Keeping the Enemy Close: In "Gods and Monsters", Harrow hears Layla kill one of his mooks in Alexander the Great's tomb, and when the convoy reaches the police roadblock, he is clearly keeping watch on her out of the corner of his eye.
- Kick the Dog:
- He purposefully attacks a van full of fleeing Cairo citizens just to give himself a bit of breathing room, knowing one of his opponents would cease their attack on him to save the bystanders.
- When he gains the upper hand against Marc in their final battle, he yells out that without him acting as a "weed" to them, his family would have been happy and his brother would still be alive.
- Knight Templar: He's a devout worshiper of the Egyptian goddess Ammit, who according to myth, had grown weary of waiting for people to die before judging them, instead of setting out to judge humans for any evil acts that they have not yet committed. He uses Hitler, Pol Pot, and Nero as examples of people Ammit could have punished before they could massacre innocent people in his speech to Steven. Arthur unflinchingly kills an elderly woman who claims to have been good her entire life after his Power Tattoo indicates that her heart is "evil", because doing so is Ammit's will.
- Laser-Guided Karma:
- In "The Friendly Type", Harrow uses Marc's DID against him during his trial before the Ennead. After his defeat in "Gods and Monsters", Harrow himself is locked in a psychiatric institution.
- After judging countless people for crimes they hadn't yet committed, Harrow and Ammit are executed by Jake Lockley on Khonshu's orders to avert the possibility that they may cause harm in the future.
- Legacy Character: He's at least the second avatar of Ammit, as he makes reference to a previous avatar (later revealed to be Alexander the Great) who was gifted her staff and betrayed her at some point.
- Let's Get Dangerous!: After spending most of the miniseries proselytizing and manipulating, Harrow proves in "Gods and Monsters" that he's very capable in a fight now that he's directly empowered by Ammit, holding his own admirably against Marc, Steven, and Layla at the same time.
- Lightning Bruiser: Following his empowerment by Ammit as her new avatar, Harrow's strength, speed, and resilience are equal to that of Moon Knight.
- Magic Staff: Arthur carries an ominous-looking staff (tipped with two crocodile heads), said to be a gift from Ammit to her first avatar, that he partially uses as a Classy Cane, but he primarily uses it to summon strange jackal creatures from beneath the Earth. When the staff is in use, it occasionally glows an ominous purple color. The staff can also transform into an ornamental axe when used in combat.
- Manipulative Bastard: When summoned before the Ennead, Arthur Harrow claims - more or less truthfully - that Khonshu is a vindictive, abusive god who has been using Marc Spector for his own petty agenda. He also uses his own past as a victim of Khonshu to deflect suspicion, leaving Marc effectively the one on trial. The fact that Marc himself cannot deny any of his words — because Harrow manages to trigger his mental health issues and provoke him into attacking — and Khonshu's lack of diplomacy does little to dissuade the Ennead.
- Mirror Character: To Thanos. Both of them are Affably Evil Well-Intentioned Extremists who genuinely believe that the culling of a large number of people is for the greater good of society, and they both have loyal supporters of their respective causes. They differ in that while Thanos is willing to let anyone survive his Badass Fingersnap as long as the total number of survivors is half of their population, Harrow specifically targets those deemed unworthy, and is more than willing to cull every last one of them so the selected worthy few can thrive.
- My God, You Are Serious!: In "The Goldfish Problem", when he first meets Steven Grant, he thinks the man who stole his scarab is messing with him as he desperately sputters about his job at a museum and claims an Evil Hand is stopping him from handing the artifact back. It's only when he visits the museum himself and sees Steven working there that he realizes there is more to the mercenary than is first apparent.
- Mystery Cult: He's the leader of a cult that worships the Egyptian goddess Ammit, with numerous people bowing down to him.
- Names to Run Away from Really Fast: A guy with the last name Harrow doesn't exactly sound like someone you wanna make friends with. Sure enough, he's a cult leader with aspirations to end an unimaginable amount of lives in the name of peace.
- Near-Villain Victory: In the series finale of Moon Knight, Harrow successfully unleashes Ammit, begins the process of judging the entire world (starting with Cairo), and overwhelms Marc, Steven, and Layla in a fight with the help of his disciples. His victory seems assured until Jake Lockley comes out and manages to defeat them all offscreen.
- Never My Fault: After shooting Marc, Harrow somberly remarks that he can't save people who aren't willing to save themselves, implicitly blaming Marc for Harrow having shot him.
- Nice Job Fixing It, Villain:
- Harrow leaves the scarab with the system's body. Layla picks it up, using it to follow Harrow out of the tomb by tracking Ammit now that his followers have her statuette. This allows her to free Khonshu later, as well as become Taweret's Avatar.
- Killing the Ennead's avatars works against Harrow, as it convinces Osiris to allow Marc and Steven to return to the world of the living to thwart Harrow's plans.
- Nice to the Waiter: He's kind to his various followers in the Disciples of Ammit, knows most of them by name, and compliments their good work. He's also not above a brief soccer match and some light-hearted banter with their younger ranks.
- No Historical Figures Were Harmed: Ethan Hawke cited several real-life people that he drew inspiration fromnote, but he particularly noted that Branch Davidian cult leader David Koresh
was a major influence on his portrayal of Harrow. - No, Mr. Bond, I Expect You to Dine: When he has his people kidnap Steven, he first treats him to a nice bowl of lentil soup before he begins to deal out threats and ultimatums.
- No-Nonsense Nemesis: With Marc cornered but refusing to surrender, Harrow decides to simply produce a revolver and shoot him twice in the chest the moment he gets an opening.
- No Place for Me There: He wants to create a utopia where Ammit wipes out all "evil" in the world. Once Ammit is released and she tells him his scales are unbalanced, Harrow fearfully admits he hoped to release her, as his penance would balance his scales. When that's not the case, he urges her to kill him and instead use one of his followers as her avatar, as he claims they're more worthy than him. Ammit, however, believes Harrow is best suited to help her achieve her goals and still picks him as her avatar.
- Non-Action Big Bad: Harrow is not a particularly physically intimidating or martially-skilled man (though his status as Khonshu's ex-avatar implies that this wasn't always the case), preferring to rely on his guile and charisma and let summoned jackals or his human followers do the heavy lifting. Subverted in Episode 4, when he shoots Marc twice in the chest with a revolver, and averted entirely in the series finale when empowered as the avatar of Ammit, as he proves capable of throwing down directly with Moon Knight and Mr. Knight.
- No Sense of Personal Space: Has a tendency to get too close to Steven for his comfort, including grabbing his hands and cleaning his clothes as if he were a close friend.
- Not So Above It All: The normally composed and eloquent Harrow treats Khonshu with a far more casual demeanor during their final meeting, even making a "blah blah blah" hand motion as the moon god pontificates.
- "Not So Different" Remark: As Marc desperately struggles to escape Dr. Harrow's office, he tries to calm him down by mentioning his own long history of mental illness and letting him know he understands what Marc's going through.
- Not So Stoic: Harrow is normally very calm and composed, but there are moments where this demeanor falters:
- When he attempts to judge Steven in the first episode, Harrow is visibly unsettled when the scale tattoo on his arm fails to judge Steven as either good or evil, noting the "chaos" in Steven's soul with a disquieted tone.
- While in the caves leading to Ammit's tomb, Harrow is visibly sweating, either from the Egyptian heat or out of fear from being underground with the tomb's undead guards, who had butchered a number of his men.
- While fighting Marc in the series finale, Harrow raises his voice for the first time in the series, angrily describing Marc as a "weed" that Ammit would have killed when he was a child if she'd been free, even throwing out a needlessly cruel remark about Marc's dead brother.
- When Jake Lockley is about to shoot him, Harrow visibly panics and tries to make a plea for mercy before Jake executes him.
O-Y
- Oh, Crap!: Harrow has this expression when Khonshu reveals he has another avatar at his disposal — Jake Lockley, the third, secret alter. Harrow can only get out a panicked "Wait!" before Lockley shoots him dead.
- Ominous Walk: As Marc lays prone and defeated on the ground in the final battle's Darkest Hour, Harrow slowly strides up before planting his staff on Marc's chest, assaulting him with a torrent of purple energy.
- Omniglot: He is fluent in English, Ancient Egyptian, Mandarin, Spanish, Coptic, and Arabic. He also encourages his followers to learn at least three different languages to better themselves.
- O.O.C. Is Serious Business: Harrow is very set and firm in his adoption of Ammit's purported Black-and-White Morality (judging the people in his cult without any hesitation). And yet, when he tries to measure Steven's heart by his tattoo scales, their wild swinging makes him realize he is confronted by someone who cannot (as yet) be neatly categorized as either.
- The Pawns Go First: As Marc and Layla ready themselves to fight him 2-on-1, a group of his followers arrive and stands in their path. He stands back and waits for them to be defeated before re-entering the fray.
- Phony Degree: The degree Dr. Harrow has proudly hung on the wall in his office leaves a lot to be determined. It bears no signature and makes no mention of which university he actually graduated from, only referencing a generic "School of Psychological Sciences".
- Polite Villains, Rude Heroes: Harrow is soft-spoken, polite, and charismatic, while Khonshu is a blunt and rude bully and Marc is abrasive and moody at the best of times. Despite this contrast, it's very clear to both Steven and the audience who the villain is in this equation. Also Zigzagged, as Steven is also a polite and kind man in sharp contrast with Marc.
- Politically Incorrect Villain: Downplayed; Harrow treats Steven with a degree of pity regarding his DID, but refers to him as "broken", showing a lack of concern for his mental health. Later, in "The Friendly Type", Harrow uses Marc's mental illness as an argument that he is unreliable and easily manipulated, calling him "insane" and giving the impression that Harrow pities the mentally ill, but doesn't really have much respect for them. How much of this is genuine and how much is for the benefit of the judges is deliberately unclear.
- Power Tattoo: Harrow has one of the Scales of Justice on his forearm, which actually shifts around when he's judging an individual to see if they are good or evil.
- Precrime Arrest: Harrow claims that Ammit is capable of this, punishing people who are destined to do evil, with his judgement ritual enacting Ammit's will by killing those who are supposedly guilty of future crimes. Steven is quick to point out that, much as Harrow dances around the issue, this amounts to murdering innocent people.
- A Pupil of Mine Until He Turned to Evil: As it turns out, Harrow was the previous avatar of Khonshu, but gradually became disillusioned with his service to the god due to only being able to punish people after they had committed crimes. This is what led to his Face–Heel Turn.
- Purple Is Powerful: He wields the Staff of Ammit, which glows an ethereal purple whenever he channels the power of Ammit through it. When Ammit grants him the full power of an avatar, his eyes briefly glow purple.
- Rank Scales with Asskicking: He's the leader of the Disciples of Ammit, and is the only one of them who puts up a tough fight against Marc, Steven, and Layla.
- Real After All: After Steven wakes up from his "dream" of the village in the Alps, he convinces himself that none of it was real and Harrow was a figment of his imagination. That same morning, he spots Harrow giving him a Death Glare on the morning bus, making it abundantly clear he was not the product of a dreaming mind.
- Religion of Evil: Played with. Harrow's cult focuses on the worship of gods from Egyptian mythology, including Ammit and Anubis. One of the rituals Harrow performs involves judging people based on a mysterious moving tattoo on his arm. It appears that, within the cult, the only people who are judged are volunteers. Everything we see of them indicates that it's a genuinely pleasant, happy, multicultural community, but those who fail the test are, in fact, summarily executed by Ammit and their souls consigned directly to the Duat.
- Revolvers Are Just Better: He wields a revolver which proves to be much more effective in putting Marc out of commission in "The Tomb" than any of the automatic weapons his disciples have menaced him with since the first episode of the series.
- Rule of Symbolism: He spends most of his time wearing red robes. In Egyptian mythology, the color red was associated with violence, disorder, and suffering, making this a pretty appropriate choice for the miniseries' Big Bad who also turns out to be just as disordered as those he's killed.
- Sadist: He privately admits to the imprisoned Khonshu that the part of his service to him he enjoyed the most was delivering the moon god's brutal form of vengeance to criminals. He eventually to grew to feel immensely guilty about this and dedicated himself to Ammit as his own form of penance, but it certainly paints his actions in the present day to be something of a Dog-Kicking Excuse.
- Sanity Slippage: Having his mind merged with Ammit's does a number on his psyche. He is seen hallucinating sand in a glass of water, and he acts uncharacteristically confused and dazed. To make it crystal clear just how badly it has affected him, he's been committed to a psychiatric hospital.
- Sealed Inside a Person-Shaped Can: In the finale, Ammit is sealed within Harrow because she can only be destroyed while inhabiting a mortal vessel instead of a statue like before. After Marc and Steven refuse to kill Harrow, Khonshu uses Jake Lockley, the mysterious third alter and Khonshu's true avatar, to do the deed instead.
- Self-Punishment Over Failure: The opening scene of Moon Knight has Arthur smashing a drinking glass that he had sipped water from earlier, and then putting the fragments of glass in his sandals as he walks around. Ethan Hawke described it as Arthur attempting to atone for his sins in a way that emphasizes his own self-loathing.
- In episode 6, he offers his own life to Ammit, assuming all the things he had done on the path to awakening Ammit would doom him to an eternity in the Duat via her judgement. He has to be talked into remaining on Earth as her avatar.
- Shockwave Stomp: Soon after Layla joins Marc and Steven in battling Harrow in Cairo, he slams his staff down to cause a blast of purple energy to billow out from the contact point and knock his opponents off of their feet.
- Shut Up, Kirk!: Steven's Kirk Summation regarding his willingness to execute children leaves his faith in Ammit completely unshaken, and he simply moves on to more aggressive tactics to ensure Grant's cooperation.
- Smug Snake: Harrow spends the entirety of the series in a state of overconfidence and the belief that he's completely untouchable until the last scene when he realizes Khonshu has another avatar in the form of Jake Lockley, who's more than willing to shoot him dead.
- Super-Empowering: He gains the ability to do this after Ammit is freed, granting the Disciples of Ammit the ability to perform the ritual of judgement themselves upon anyone they lay their hands on.
- Superhero Movie Villains Die: He's shot to death by Jake Lockley in the The Stinger of Episode 6. It also ends up being a case of Adaptational Karma, given that comic book Harrow was a Karma Houdini in his sole appearance.
- Super-Reflexes: His reaction speed is enhanced when he becomes Ammit's avatar, as shown when he effortlessly knocks away a truncheon thrown at him full force by Mr. Knight.
- Super-Toughness: When he becomes the avatar of Ammit, he manages to shrug off both Marc, Steven, and Layla's attacks, without the god-powered armor they all possess.
- Tempting Fate: When he is confronted by Khonshu in The Stinger, he claims that the moon god has no way to hurt him without an avatar present to do the deed. Cue a cheery Jake Lockley rolling down the window with a silenced pistol in hand.
- Thwarted Coup de Grâce: He is readying a blast of magic to finish off a downed Marc when Layla makes her Dynamic Entry into the fight and knocks him away.
- Undying Loyalty: To Ammit. He's by far her most devout worshipper, and he does his best to sway others towards her philosophy by constantly singing his praises of her. Even when Moon Knight and Khonshu start to cause him serious trouble, he simply gets more determined to release her and resorts to more assertive measures. This turns out to fall in his favour, as Ammit recognizes his loyalty and sees him as the perfect candidate for her next avatar. She even gloats to Khonshu that, unlike Marc and Steven, her avatar is genuinely loyal and revering of her.Ammit: You're jealous of his loyalty!
- Utopia Justifies the Means: Harrow and the cult's goal is "Heaven on Earth", but their means to do it is resurrecting Ammit and allowing her to pass judgement on everyone, young and old alike, and killing those she judges evil. This is the point where they lose Steven.
- Villain Has a Point: The comments he makes to the Ennead about Khonshu's abusive nature towards his avatar and Marc's unwell mental state both ring true, with Marc himself even admitting that he needs help when the Ennead asks him about it.
- Villains Never Lie: Both played with and played straight in "The Friendly Type":
- Harrow is certainly dishonest with the Ennead, even if he doesn't actually lie — he claims to simply be seeing the desert without admitting to searching for Ammit's tomb. He first gives technically correct statements which make it sound like he is being persecuted by Khonshu. He then follows by triggering and provoking Marc, making him unable to rally and refute his claims. In short order, Marc and Khonshu find themselves the ones actually on trial.
- At hearing Harrow comment on her father's murder as the reason she left Egypt, Layla is unsettled, as she hadn't told anyone her reasons for leaving and wonders if what Harrow said about Marc is also true. But Harrow is again being technically accurate while giving the wrong impression — namely, that Marc killed her father. Marc was present when he died, but he wasn't the one to kill him. His mercenary partner was, and Marc actually tried to stop him, but got a bullet in the gut for his trouble.
- Villain Reveals the Secret: Harrow gets under Layla's skin by revealing to her that Marc is not all that he seems to be.
- Villainous Valour: Despite his ruthless methods and twisted philosophy, Harrow is far from a coward, often being right next to his followers while they carry out his will. When Ammit is finally freed, Harrow is perfectly willing to accept death when the goddess informs him that his own scales don't balance. Later, after being empowered by Ammit, Harrow proves more than willing to take on both Moon Knight/Mr. Knight and a newly-empowered Layla at once, holding his own and even managing to overpower Marc during the resulting battle.
- Villains Want Mercy: Harrow's reaction right before Jake Lockley shoots him.
- Visionary Villain: His actions are in service of bringing about a "heaven on earth", populated with none but the kindest and noblest of human souls. Unfortunately, he seeks to achieve this by damning all of those not considered worthy to eternal torment with no chance to ever redeem or change themselves.
- Voice of the Legion: Harrow speaks like this in "Gods and Monsters" shortly after Marc and Layla use his body as a vessel to permanently contain Ammit.
- Waistcoat of Style: He wears a sharp grey waistcoat as Dr. Harrow. It's especially noticeable since his attire previously consisted of little more than simple burgundy tunics.
- Weaksauce Weakness: The judgement ceremony he can perform fails to work properly on Steven because having multiple people in one body confuses the ritual.
- Well-Intentioned Extremist: He appears to genuinely believe Ammit will make the world a better place if his rituals work, despite the quite ruthless methods he and his goddess use to bring about their better world. This is shown even more when he takes Steven to one of his "sanctuaries" in London; it took a lot of horrible acts to build it, but the community is very diverse, thriving, and happy. Harrow even indicates that he sincerely wants the world to be just like it and will follow his goddess Ammit anywhere she commands to make it happen.
- We Are Everywhere: Steven Grant encounters several of Arthur's followers in both the U.K. and an unknown location in Europe (the Alps are referenced in the episode and the people and culture seem Germanic, so it's most likely Germany, Switzerland, or Austria). They include people who range from tourists and small-town villagers, to even security guards and police officers.
- Wicked Cultured: Harrow is well-versed in Egyptian history, has learned to speak at least six languages, and can quote Hamlet. He also encourages his followers to be this, motivating them to learn at least three languages each to better themselves.
- Would Be Rude to Say "Genocide": When Steven calls Harrow out on the fact that, logically, his and Ammit's plans would involve murdering children who would potentially grow up to do wrong, Harrow doesn't deny it, but compares it to amputating a diseased limb. Steven has none of it, pointing out the holes in Harrow's logic.
- Would Harm a Senior: When an elderly woman is deemed to be guilty by the Scales, he doesn't hesitate to use his powers to administer Ammit's justice.
- Would Hit a Girl: Arthur expresses no hesitation to potentially kill women if Ammit's Scales of Justice judge them to be evil. He also has no qualms about attempting to kill Layla in "Gods and Monsters".
- Would Hurt a Child: Arthur expresses no hesitation to potentially kill children if Ammit's Scales of Justice judge them to be evil, comparing it to amputating a diseased limb. Steven is openly disgusted by this.
- You Are What You Hate: He has made it his life mission to exterminate those with unbalanced souls who inhabit the earth. Ammit swiftly reveals to him after she is released that he himself has yet to balance out his own scales, despite his efforts.
"You can't hurt us."
