BEWARE OF SPOILERS!
Played By: Harold Perrineau
First Appearance: "Non Est Asylum" (Constantine 1x1)
An angel sent to watch over John to warn him of the dark forces that are starting to rise on Earth.
- All-Powerful Bystander: Manny probably could destroy most Monster of the Week threats John faces with a swipe of his hand, but he doesn't because angels cannot interfere directly with the mortal realm.
- Beware the Nice Ones: He is able to annihilate a Fallen Angel within seconds.
- Big Bad: Of Constantine, though John never finds out about it (on-screen). The Brujería work for him, which means he is behind the Rising Darkness.
- Celebrity Paradox:
- Cryptic Conversation: Mocked by John, but he explains this is actually how he has to talk due the Angel's code of non-interference.
- Deadpan Snarker: Stands toe-to-toe with John in Snark-to-Snark Combat.
- Demonic Possession: Well, Angelic Possession actually, but basically the same thing. Manny has a habit of talking to John by possessing people nearby to him.
- Don't Fear the Reaper: He often shows up when people are about to die.
- Evil All Along: The Brujería work for him.
- Holier Than Thou: Manny frequently calls Constantine out or questions the hard choices Manny has to make and states to the angel Imogen he thinks angels could do better than humans and is frustrated at how humans constantly fail and angels have to act as their "crutch." He doesn't seem to notice that Constantine often does not have a better alternative (largely thanks to Manny not being able to interfere), the many angels that "fell" and continue to pursue evil, and the general human condition.
- Humans Are Flawed: Expresses this point of view. Constantine agrees with him in this regard. Also a view shared with the angel Imogen. Who murdered one of her human charges to see if she could, this leading to her fall.
- Morality Chain: He tries to act as this for Constantine. One particularly intense example was "A Feast For Friends", where Manny showed up for no other reason other than to advise against a rather morally questionable decision by Constantine.
- Only Known By His Nickname: Manny is not his true name, since knowing it would give John a measure of power over him.
- Screw the Rules, I'm Doing What's Right!: Despite his orders of non-interference Manny intervenes to save Zed from a murderous fallen Angel.
- Spirit Advisor: Of sorts to John, though Constantine complains he's actually very unhelpful.
- Stealth Hi/Bye: It's a Running Gag for him to vanish mid-conversation, much to John's annoyance.
- Supernatural Gold Eyes: Par the course for angels in this show, he has golden eyes.
- The Man Behind the Man: The Angel pulling the strings of the Brujería.
- Time Stands Still: Can pause everything but himself and someone else when he wants to have a private conversation.
- What Happened to the Mouse?: Well it's obvious that Constantine put a stop to his Evil Plan sometime between the end of Constantine and John's joining Legends of Tomorrow, but the specifics are never elaborated upon.
Played By: Megan West
First Appearance: "Blessed Are the Damned" (Constantine 1x7)
A fallen angel.
The Ruling Triumvirate of Hell
- Big Bad Duumvirate: Or Triumvirate. The three co-rule Hell as three of the most powerful demons.
- Demon Lords and Archdevils: They are the most powerful of all demons, and the rulers of Hell.
- Evil Old Folks: They take the form of middle-aged business men.
- Greater-Scope Villain: For Season Four of Legends of Tomorrow. Overthrowing them is Neron's goal, but the Triumvirate only take part in the story when Constantine literally walks right up to them and makes them get involved.
- Sadistic Choice: They force Constantine to choose between saving either Astra's or Ray Palmer's soul.
- Stupid Evil: They know that Neron is seeking to overthrow them, but they can't resist the chance of torturing Constantine even though he's their best bet at stopping him.
- Villain Teleportation: They are demons, and they have the power to disappear and reappear at will.
Satan / The First of the Fallen
Voiced By: NA
Played By: Beau Daniels
First Appearance: "The Devil's Vinyl" (Constantine 1x3, voice), "Terms of Service" (Legends of Tomorrow 4x15, self)
Appearances: Constantine | Legends of Tomorrow
The first angel to fall from God's Grace.
- Alternate Self: Since Lucifer is canon in the multiverse, he is technically the Earth-1 counterpart of Lucifer Morningstar, both being Satan.note
- Arch-Enemy: To Constantine. Papa Midnite might be John's rival in magic, but the First of the Fallen is John's most vicious adversary by virtue of being the first demon.
- Deal with the Devil: It's established in Constantine that he offers service to humans in exchange for their souls.
- Greater-Scope Villain: Of Constantine, especially the episodes "The Devil's Vinyl", where a vinyl with his voice recorded on it drives people to kill themselves, and "Waiting for the Man", where one of his followers sacrifices little girls to him.
- Good Wings, Evil Wings: Unsurprisingly, his pair of wings has a utterly demonic appearance.
- Red Baron: His epithet is the First of the Fallen.
- Fallen Angel: The first one to fall in fact.
- Satan: Old Scratch himself, the first fallen angel and one of the co-rulers of Hell.
- Unseen No More: He was mentioned a few times on Constantine (for instance, as the source of a Brown Note recording that drives the plot of one episode) before he properly appeared on Legends of Tomorrow.
- Winged Humanoid: He has wings, although he doesn't show them all the time. Considering he's a Fallen Angel, that was to be expected.

First Appearance: "Terms of Service" (Legends of Tomorrow 4x15)
Appearances: Legends of Tomorrow
The second member of the Triumvirate.
Played By: Bill Croft
First Appearance: "Terms of Service" (Legends of Tomorrow 4x15)
Appearances: Legends of Tomorrow
The third member of the Triumvirate.
- Beelzebub: Yup, that's who he is.
- Ensemble Dark Horse: In-Universe. Despite being apparently the least popular of the Triumvirate, he's Constantine's personal favorite.
- Flat Character: Doesn't stand out in any way from his two colleagues.
- Minor Major Character: One of the three overlords of Hell, but gets next to no focus.
Voiced By: Joey Phillips
First Appearance: "Non Est Asylum" (Constantine 1x1)
Appearances: Constantine | Legends of Tomorrow note
The demon who took Astra Logue to Hell as a result of John Constantine's arrogant actions.
- Aborted Arc: Thanks to a Retool after the pilot was refilmed, Nergal is only the villain for Constantine's pilot and isn't much in the series proper. He is given a passing mention in Legends of Tomorrow to explain what happened between the end of the show and Season 4 of Legends and appears in flashbacks in "Terms of Service" and "A Head of Her Time".
- Arch-Enemy: To Constantine. Even after he took Astra, Nergal has sent his minions for others John cares just to twist the knife against him further.
- For the Evulz: He's a demon; it's what he does.
- Greater-Scope Villain:
- In the Constantine pilot; Furcifer is hunting Liv down on Nergal's orders.
- He is this for Legends Season 5. Astra Logue is the main antagonist, but she would have not turned evil had Nergal not take her to Hell.
- Mesopotamian Monstrosity: Nergal’s name is that of a god from Mesopotamian Mythology. In the original comics, the connection was made more explicit.
- Small Role, Big Impact:
- By taking Astra to Hell, he set off Constantine's entire character arc.
- In the gap between Constantine and Legends he gave up his ownership of John's soul to Neron, setting off the story arc for Legends Season 4.
- As revealed in "Terms of Service", Nergal taking Astra to Hell ultimately set her up to be corrupted into a demon hell-bent on making Constantine suffer.
First Appearance: "Non Est Asylum" (Constantine 1x1)
A demon sent by Nergal to kill Liv Aberdine, Furcifer is the first demon of the series that John faces.
- The Dragon: To Nergal, in the pilot.
- A God Am I: "Down here, I'M GOD!" He says it as he notices he's absolutely surrounded by electricity.
- Fluffy the Terrible: The name "Furcifer" sounds like a good name for a demon, until you learn that it's actually a type of Chameleon.
- Lessened somewhat when you realize that it’s actually Latin for “Slaver, Yoke-Bearer, or Scoundrel”.
- A Form You Are Comfortable With: When he is summoned by John, he takes on John's form, complete with Black Eyes of Evil. In the original pilot, however; Furcifer didn't take John's appearance but a random security guard. His true form is something else entirely.
- Power of the Storm: Able to summon powerful lightning and tempests.
- Shock and Awe: Has control over electricity which manifests in control over power lines, a city's electrical grid and even dead bodies.
- Starter Villain: His function is pretty much to foreshadow larger threats.
Played by: Christian Keyes (when possessing Desmond), Brandon Routh (when possessing Ray)
First Appearance: "Dancing Queen" (Legends of Tomorrow 4x3)
Appearances: Legends of Tomorrow
A demon who is after Constantine's soul and the Legends' main adversary in Season Four.
- Adaptational Ugliness: Comics Neron had a humanoid appearance and quite an attractive one at that. This Neron has a Nightmare Face whenever he possesses a host and a Living Shadow when in his true form.
- Adaptational Wimp: Comics Neron is stated to be the most powerful magical being in the DC universe, being a Nigh-Invulnerable Reality Warper. This Neron by contrast has restricted mobility and is forced to possess human hosts, and while quite troublesome to fight, it is relatively easy to bring him down and most definitely killable. As opposed to a godlike Lord of Hell, he's comparable to a more standard tier demon that Constantine regularly deals with, albeit a very persistent one.
- Arch-Enemy: He quickly becomes a very personal enemy to several of the heroes:
- To John Constantine, for forcing him to banish his lover Desmond to hell and then taking over the latter's body just to torment John.
- To Nate Heywood, for manipulating and then later killing his father Hank.
- To Nora Darhk, who is framed for Hank's death and whom he tries to manipulate into letting him possess her, playing mind games with her, involving her own deceased father.
- Big Bad: Of Legends Season 4.
- Big Bad Duumvirate: With his lover Tabitha, after she is freed nearing the end of Legends Season 4.
- Demonic Possession: Possesses Ray after Nora and John pull him out of Desmond.
- The Dreaded: The Fairy Godmother willingly chose to be imprisoned in Hell again rather than oppose him. Subverted later when it was more out of love for him than fear, but he still is this to John.
- Even Evil Has Loved Ones: As evil as they both may be, Neron genuinely loves Tabitha.
- Evil Is Petty: Wanted Constantine's help to overthrow Hell, even gaining ownership of soul to do so - John told him to piss off. Things got messy from there, John's lover Desmond made a deal with Neron to save John, but unfortunately this tethered him to Neron so when John banished Neron to Hell, Desmond was damned too. Nero gets a kick of using Desmond's face and voice just to mess with John.
- Faux Affably Evil: Neron is witty and charming, acting very friendly towards his enemies. At the same time, he can't seem to go more than a few minutes without saying or doing something to remind the viewers that he's a particularly nasty demon.
- Hate Plague: He's a a walking, talking, and really quite gleeful one. He causes multiple fights at his motel just by arriving, and his influence causes John and Nora to briefly be at each other's throats, and Nate to punch Ray, although the Legends being aware of his power allows them to get a grip on themselves before things go too far.
- I Gave My Word: Despite being an evil demon, he is bound to keep his word whenever he makes a deal with somebody. This proves to be his undoing: As he promised to spare Nate in exchange for Ray's body, Constantine and Nate trick him into killing the latter, which causes him to lose Ray's body.
- Killed Off for Real: After getting expelled from Ray's body, Constantine finishes him off.
- Leitmotif: "Pop Goes The Weasel." He frequently whistles it, which makes bystanders in his proximity become extremely violent and destructive.
- The Man Behind the Man: He's Hank's superior in the half-baked scheme to use magical creatures as living weapons.
- The Mind Is A Play Thing Of The Body: In-series. He takes on a few personality traits of whoever he is possessing. While inside Desmond's body, he is an Affably Evil calm, stoic and always in-control demon. While inhabiting Ray's body, he picks up some of his dorky traits and silly mannerisms. None of these "borrowed" traits make him any less vile and loathsome however.
- Nightmare Face: Lets just say his face is not something people with Trypophobia should look at.
- Pungeon Master: While inside Ray's body, he litters his demon-tracking app presentation with genuinely cringeworthy puns. No doubt a minor side-effect of possessing Ray's body.
- Rogues' Gallery Transplant: Neron is typically a Justice League villain.
- Sadist: According to John, he doesn't just want to win, he wants to win the cruelest way possible.
- The Starscream: He wants to overthrow the ruling triumvirate of Hell.
- Supernatural Fear Inducer: In addition to his Hate Plague he also naturally plays up on people's fears. He wants to unleash the magical fugitives the Time Bureau captured on humanity so they'll give up their souls to him in exchange for safety.
- Vile Villain, Saccharine Show: The excessively silly Season Four gets balanced out by the fittingly despicable and nightmarish Neron.
- You Have Outlived Your Usefulness: Murders Hank Heywood after the latter tries to stand up to him.
Aliases: "Gary Jr.", Canine of Chaos
Voiced By: Andrew Morgado
First Appearance: "Ship Broken" (Legends of Tomorrow 5x10)
Appearances: Legends of Tomorrow
A hellhound which impersonated a Jack Russell Terrier that Gary found in Hell and which was adopted by him as his Emotional Support Animal, before revealing his true colours.
- Been There, Shaped History: He was behind the "Son Of Sam" murders.
- The Dog Was the Mastermind: Who would've thought that an adorable, little Parson Jack Russel terrier would try and mind control the Legends to kill each other?
- Dragged Off to Hell: With Astra's help, who provides him with his true name, John banishes Marchosias back to hell.
- For the Evulz: He isn't working for the Fates; he just seized an opportunity to wreak havoc.
- Hell Hound: His true form is that of a burning, hellish hound.
- Mind Control: He is able to influence people into doing whatever he wants, with no memory of it afterwards.
- No-Sell: Being a Hell Hound, Marchosias is naturally unaffected by Mick's flamethrower.
- One-Winged Angel: Marchosias goes from his Parson Jack Russel form to a fiery hellhound.
- Power Echoes: Has a demonic sounding voice that reverberates.
Species: Interdimensional Imp
Portrayed By: Peter Gadiot (season 2), Thomas Lennon (season 5)
First Appearance: "Luthors" (Supergirl 2x12)
A mysterious trickster from the Fifth Dimension.
- Achilles' Heel: If he can be tricked into saying, writing or even typing his own name backwards, he'll be banished back to the 5th Dimension.note
- Adaptational Attractiveness: He's not a 3' imp in a bowler hat - he's played by British heartthrob Peter Gadiot. Downplayed in season 5 where he's played by the more homely Thomas Lennon, though still fairly tall and attractive compared to most adaptations. He explains that this is his real appearance and he took on a dashing form earlier when trying to woo Kara.
- Adaptational Badass: Most versions of the character are 90-pound weaklings and are helpless without their powers. Not this one.
- Adaptational Curves: Instead of being 3 inches short and scrawny, he's tall and fit in his first body.
- Adaptational Dye-Job: He has white hair in the comics due to his age, while both of his forms are brunettes here.
- Adaptational Personality Change: In the comics, Mxy is a trickster imp whose primary motivation is trolling Superman. Here he's a Stalker with a Crush fixated on Supergirl, though he later comes around.
- Age Lift: Usually depicted as a balding old man. Here, he's around the late 20s to early 30snote . His later appearance splits the difference and shifts him more into a middle aged man.
- Alliterative Name: Mr. Mxyzptlk.
- Arson, Murder, and Jaywalking: He claims the only things he can't do with his powers are: make someone fall in love with him, stop someone from killing themselves, and make someone drink orange juice.
- The Atoner: In Season 5, he has been ordered to atone for his mischief by helping all of the people he antagonized in the past.
- Badass Fingersnap: He sometimes uses fingersnaps to initiate his reality distortion.
- Beware the Silly Ones: This version of Mr. Mxyzptlk is far more casually murderous than the mischievous imp of the comics. J'onn and Mon-El even note that all 5th dimensional beings love to party, but are dangerous.
- Brought Down to Badass: When his reality warping powers are temporarily negated, he boasts that he still knows his way around a fist fight and proves it by taking on Mon-El.
- Brought to You by the Letter "S": Parodied: he dons a Superman outfit emblazoned with the letter "M" in a pentagonal shield. Kara's not amused.
- Cloud Cuckoolander: To be fair, it's probably hard to be of sound mind when you can bend the laws of the Universe into a pretzel.
- Composite Character: Mxy takes on a composite role and is the original owner of a composite object. In the comics, Hat, of Manchester Black's Elite, is a human man who gained a mystical hat from a demon; on Earth-38, he is an alien with supernatural powers granted by the hat of a reality-warping fifth-dimensional Imp. Mxy takes the place of the demon who gave Hat his powers and Mxy's trademark hat is rolled together with Hat's demonic hat.
- A God Am I: He boasts to Mon-El, "I'm a god, and you're a loser."
- Good Feels Good: After helping Kara, he contemplates that being a better person genuinely feels good to him.
- Heel–Face Turn: In his second appearance, he has stopped antagonizing people and instead tries to help Kara fixing her relationship with Lena.
- I Just Want to Be Loved: He laments this as he's being banished back to the 5th Dimension. Kara says you can't force love, you have to let it find you.
- I Lied: When Mon-El challenges him to a duel for Kara's hand, Mxyzptlk provides pistols that he claims can kill even him. Mon-El immediately shoots him, but it does nothing, then he calls him a fool for thinking he would give him a chance at victory.
- Moment Killer: Interrupts a romantic moment between Kara and Mon-El at the end of "Luthors".
- No Ontological Inertia: All of the damage he causes, such as the destroyed statue of Jor-El, resets when he's banished back to the 5th dimension.
- Not Wearing Tights: Mxy is usually wearing colorful tights in the comics. Like all Live-Action Adaptation of the character, he's wearing black clothes. The closest thing he wears to a spandex is the fake Superman suit.
- The Nth Doctor: It's revealed in "It's a Super Life" that he can glamour his appearance, which accounts for being played by different actors.
- Physical God: He thinks of himself as a god. Given he can warp reality on a whim, he has a right to this claim.
- Reality Warper: Mxyzptlk is from the 5th Dimension, where the laws of physics aren't quite so mandatory, and its inhabitants can alter reality as easily as snap their fingers.
- Rogues' Gallery Transplant: Mr. Mxy usually spends his days annoying Kara's cousin Clark.
- Smug Super: Thanks to his vast powers, he mocks Mon-El at every turn as an inferior suitor for Kara.
- Stalker with a Crush: He pops up at the end of "Luthors" to declare he's in love with Kara. He later says he's been observing Kara from the 5th Dimension.
- Unexpected Character: Despite his comic counterpart being a regular thorn in the Super family's side, he has no relevance to his debut episode's plot and shows up completely unannounced. Of course, ol Mxy's kind of infamous for such behavior.
- Yandere: He makes it clear he is willing to go as far as destroy the Earth until Kara agrees to be his wife.
Species: Interdimensional Imp
Portrayed By: Peta Sergeant
First Appearance: "Phantom Menaces" (Supergirl 6x3)
A former Princess from the Fifth Dimension, who got imprisoned in the Phantom Zone.
- Adaptational Attractiveness: In the source material she was ugly, and while not a hag, was certainly not the brunette, feminine Eurasian-looking woman she is in this adaptation.
- Adaptation Dyejob: Gsptlsnz in the comics is a red-head or sometimes blonde but here she is brunette as her actress is.
- Adaptation Species Change: She's an imp like in the source material, but these imps are human in esthetic with no fifth-dimensional mind-bending form.
- Ambiguous Situation: She claims that her father King Brpxzout, out of fear of being replaced, killed his son and then banished Nyxlygsptlnz to the Phantom Zone. It's not clear how much of this was true.
- Big Bad: With Lex Luthor Out of Focus she becomes this for the sixth and final season. However, it then turns into a Big Bad Duumvirate when Lex assists her due to being in love with her.....and then briefly into a Big Bad Ensemble when the two break up and fight.
- Dragged Off to Hell: Her ultimate fate, alongside Lex, due to the latter summoning a legion of Phantoms, who then drag them off to the Phantom Zone, feeling their fear.
- Evil All Along: She turns out to have been manipulating Kara in order to get home herself.
- Faux Affably Evil: Once she drops the mask.
- Final Boss: She is Supergirl's very last opponent along with Lex for the entire series.
- Laughably Evil: Compared to other antagonists such as Project Cadmus, Mercy Graves, Reign/Samantha Arias, Agent Liberty, The Elite, Leviathan and Gamemnae who have few comedic elements, she falls under this trope due to her over-the-top behaviour and Camp personality.
- A Lighter Shade of Black: Between her and Lex, she often times gets portrayed as more sympathetic, as she initially wants nothing to do with him due to locking Kara into the Phantom Zone and also is strictly against harming Esme.
- Not Quite Dead: While she seemingly commits suicide, she is later revealed to be alive and hitches a ride towards Earth when Kara and her friends escape from the Phantom Zone.
- Power Limiter: When Kara meets her in the Phantom Zone, she wears a bracelet that seals her magic, aside from being able to see others through a crystal ball. After some encouragement from Kara, she manages to destroy the bracelet with the crystal ball breaking both her physical and mental shackles.
- Race Lift: She goes from white to Eurasian in this adaptation, and this is due to the series' Setting Update of The New '10s.
- Stupid Evil: If she had just kept up the facade until they were through the portal, she could have terrorized Earth all she wanted and gotten back to the Fifth Dimension and Kara wouldn't have been able to stop her. But instead she just outs herself as a villain for absolutely no reason.
- Unholy Matrimony: Lex and Nyxly had this relationship in the future and Lex wants to get it started again in the present. In the end, it fails, as Lillian drives a wedge between them.
Mar Novu / The Monitor
Played By: LaMonica Garrett
First Appearance: "Bunker Hill" (Supergirl 4x8)
Appearances: Elseworldsnote | Arrow | Supergirl | Legends of Tomorrow | The Flash | Batwoman | Crisis on Infinite Earthsnote
An extraterrestrial being of infinite power.
- Adaptational Species Change: He is a Maltusian since he is a Composite Character with Krona.
- Adaptational Villainy: He is much more aggressive than his comics counterpart in his plan to save The Multiverse by destroying universes that fail his test, and he shows dismissive cruelty toward anyone who calls him out on it.
- Aesop Enforcer: He ensures that Oliver learns that there are some times he can't change things and J'onn learns to let go of his past.
- Alternate Self: Played with. The Mar Novu we knew all along is actually saved from becoming the Monitor through our heroes' time travel intervention and ends up living the long and happy life with his family the Monitor wished he had. Unfortunately, it doesn't matter; in an infinite multiverse this just means a different version of Novu from another timeline created the Anti-Monitor and the Crisis happens anyway.
- Ambiguously Evil: His manipulative and secretive nature cast doubts on whether he wants to cause the Crisis or if he is trying to avert it. He's eventually confirmed to be on the level, but he's a solid Well-Intentioned Extremist.
- Ambition Is Evil: The original Mar Novu was a decent, caring person who loved his family, and in his backstory episode even jokes to his wife that his one flaw is his "overpowering ambition" as a scientist. He's more right than he knows — that one decision to pursue the time travel experiment damns the entire Multiverse.
- Back from the Dead: He get's killed by Harbinger, who is mind-controlled by the Anti-Monitor in Hour 3 of the Crisis. However, he gets resurrected, as evidence of him reuniting Oliver and Felicity a good 20 years into the future.
- Badass Cape: A Physical God capable of wiping out existence who wears a black-and-yellow cape.
- Batman Gambit:
- His gambit to bring Malefic from the Phantom Zone was a plan to make the otherwise powerful J'onn try to reform him and make up with his past in the process.
- He rescues Lex Luthor due to his wide scientific intelligence. He uses him to find the Superman that serves as the Paragon of Truth.
- Been There, Shaped History:
- It appears he's had a far bigger presence in Arrowverse history than first meets the eye. Mar Novu gave vast knowledge to Al-Fatih, the founder and first ever Ra's Al-Ghul, who then used this knowledge to found the League of Assassins. It's also implied that Al-Fatih made the League to maintain balance was something that the Monitor intimated him into doing.
- It's revealed he Was Once a Man, a scientist who tried to peer into the dawn of time and inevitably opened up The Multiverse to the Antimatter Universe and allowed Mobius the Antimonitor to discover its existence and attempt to destroy it.
- Big Bad: He is the one responsible for the events of Elseworlds, though Dr. John Deegan is the one actually using the Book of Destiny to warp reality.
- Big Good: He's become this for the whole The Multiverse with the Crisis approaching, being the one chance everyone has to continue existing. However he's still a Well-Intentioned Extremist. After he dies in Hour 3 of the Crisis, Oliver as the Spectre takes over his role for the last 2 parts.
- The Chessmaster: The Monitor spends Season 8 of Arrow, Season 6 of The Flash, and Season 5 of Supergirl manipulating events and collecting various allies, all to oppose the Anti-Monitor.
- Black-and-Gray Morality: Mar Novu is facing an unambiguously evil entity attempting to destroy all of existence. However, Mar Novu is not above doing morally grey actions like destroying entire Earths, putting people through outright torturous psychological trials or jeopardizing alternate versions of a hero to find the Paragon of Truth.
- Composite Character:
- With the Monitors as a whole, who are less benevolent than the particular Monitor he is based off in the comics.
- Since the Green Lantern Corps were Adapted Out of this adaptation, his homeworld is Maltus, and Mar Novu takes the role of Krona as the one who attempted to peer into the dawn of time to watch creation unfold.
- Cosmic Entity: He's about a textbook example as you can get and literally referred to one In-Universe.
- Create Your Own Villain: In a very literal and cosmic example of this trope, the same time travel accident that suffused the scientist Mar Novu and his protective suit with cosmic energy and turned him into the Monitor also somehow allowed the Antimatter Universe to take physical form and create an avatar based on himself, with a will and personality based on his own.
- Deal with the Devil:
- While it may be going too far to describe Novu as evil, he's still an antagonist, and during Elseworlds, Oliver strikes a bargain with him in order to save Barry and Kara's lives. At the end of Arrow Season Seven, Novu comes to collect, telling Oliver of his inescapable death in the coming crisis and recruiting him to help Novu avert the crisis.
- After the aforementioned bargain comes to pass, Felicity makes her own deal with Novu to be reunited with Oliver. While he does warn her that there is no turning back from this decision, he grants her request with no strings attached.
- Evil Is Not a Toy: He revives Lex Luthor to help in the Crisis. Unsurprisingly, things go poorly.
- Ex-Big Bad: While he was never evil, he did serve as the main threat of Elseworlds, before he went on to become the Big Good for the Arrowverse leading up to Crisis on Infinite Earths.
- For Science!: The initial motivation of his mortal self. Similar to Krona in the comics, there seems to be no practical benefit to his time travel experiment but the prospect of being the first mortal to witness the dawn of the universe itself is just too good to pass up.
- For the Lulz: When he shows up in the "Legends" Season 4 finale, it isn't to stir up trouble or collect one of the heroes to aid him combating the Crisis. He just wants to see what hijinks the Legends are causing for what seems to be his own amusement.
- A God Am I: Downplayed. He calls himself a god when Oliver confronts him in his realm. Oliver doesn't think he is, but the Monitor counters that there's no better description for what he is, so "god" will have to do.
- Good All Along: Season 8 of Arrow raises the possibility that Novu will cause the Crisis, rather than avert it, leading Oliver to seek out a means of destroying the Monitor. It's eventually established that Novu is on the side of the angels, and is even a bit kinder than he seems, although he remains a Well-Intentioned Extremist and an example of Good is Not Nice.
- Good is Not Nice: The Monitor is ultimately out to avert the destruction of the multiverse, but his methods are harsh and coldly pragmatic, while the Monitor himself is a callous jerkass, though he's not incapable of kindness.
- Greater-Scope Villain:
- For Season Seven of Arrow; Elseworlds is the only time that Novu presents a direct threat, but because of the bargain he struck with Oliver, his shadow looms over the latter half of the season and, totally independent of the season's main threat, Novu removes Oliver from the story, setting him on a path guaranteed to end with his death.
- At the end of Season Four of Supergirl, Novu brings Malefic J'onzz to Earth, laying the groundwork for whatever damage J'onn's evil brother will cause in Season Five. Subverted, as his intent wasn't for Malefic to wreak havoc, but to allow J'onn to make peace with his brother and his personal demons to ensure that J'onn is ready to fight in the Crisis.
- Season 8 of Arrow reveals Novu was responsible for creating the League of Assassins, having bestowed divine knowledge upon Al-Fatih, the man who would become the first Ra's Al-Ghul and found the League. Given the League has had a presence in almost every season of Arrow, this makes Mar Novu the Greater-Scope Villain of the entire show.
- Happily Married: It's revealed he was married to a scientist partner and lived happily with her.
- The Heavy: Spends Season Eight preparing Oliver for the Anti-Monitor, but since Mobius only appears during the Crisis most of the conflict comes from Oliver's tension with the Ambiguously Evil god.
- Hero Killer: He's very powerful and his introduction alone shows the corpses of several superheroes who failed to stop him. And since he destroyed Earth-90, he also killed the entire cast of The Flash (1990) except for the titular protagonist.
- Hidden Depths: Hour Three of Crisis On Infinite Earths reveals that Novu once had a family, and that he regrets placing his work above them.
- Ironic Name: In his origin story it turns out "the Monitor" was originally the affectionate nickname he gave his wife, who acted as his Mission Control in his ill-fated time trip and whose judgment he trusted implicitly. He has since been unwillingly placed in this role for everyone else in the Multiverse.
- Jerkass Gods: Oliver rejects the notion that Monitor is a god, and Novu himself only uses the term for lack of a better word, but he is unquestionably a being of vast power, and, despite noble goals, is quite a harsh and callous individual.
- Magical Negro: A god-like entity with an appearance of an African human male.
- My Greatest Failure: He considers allowing the Anti-Monitor to come into existence to be this.
- Named by the Adaptation: His comics counterpart is just called the Monitor, with the name Novu actually came from the Overmonitor from the comics. Though eventually the name Mar Novu would also make it into the comics based on the Arrowverse version.
- Never My Fault: As Oliver notes, he brushes off any responsibility for the harm he causes, trying to claim that he is above moral concerns. Although he does blame himself for letting his "overpowering ambition" free the Anti-Monitor.
- Nice Job Breaking It, Hero: It is revealed that his actions were the cause of the Crisis.
- He sent Earth-90 Barry to the Netherverse to silence him in Elseworlds. That way, he exposed Barry to be kidnapped by the Anti-Monitor and made to run a treadmill that empowers an antimatter cannon that destroys Earths.
- His morally ambiguous tactics made Nash Wells think he was a charlatan and led him to open the Anti-Monitor's prison and thus endanger the Multiverse as a whole.
- Him travelling to the dawn of time was what unleashed the Anti-Monitor in the first place.
- Not Helping Your Case: While his fears are rightful, his morally ambiguous approach makes him very distrusted by everyone.
- Not So Above It All: Even the grim and perpetually serious Monitor isn't safe from the crazy world of the Legends. When they put on their show at Heyworld in the season finale, Mar Novu shows up and proceeds to...just enjoy the hijinks with some popcorn and not much else.
- Not So Stoic:
- Meeting with Oliver at the end of Arrow Season Seven, the Monitor sounds genuinely regretful about Oliver's imminent, inevitable death.
- Oliver's death in the Crisis clearly shocks and even saddens the Monitor, who failed to foresee Oliver dying the way he did, and sorrowfully reflecting on his sacrifice.
- Working alongside Lex Luthor clearly tries the Monitor's patience; while justifying his presence to Kara, Novu sounds distinctly annoyed that keeping Lex around is necessary.
- Talking to Lois about his family, Novu actually laughs while reminiscing, and he laments failing to prioritize them over his work as the Monitor.
- Omniscient Morality License: Certainly believes he has one, since he's trying to save The Multiverse.
- Pet the Dog:
- Grants Felicity's request to be reunited with Oliver with no strings attached.
- When speaking to Barry about the latter's upcoming death, Novu seems as regretful as he ever gets, showing definite Villain Respect for Barry.
- In Season 8 of Arrow, despite the questions raised about Novu's morality, he does this a few times:
- He is revealed to have brought the future Team Arrow to the present day to allow Oliver to get to know his grown children before he dies and let them have a closure with their father.
- After Laurel passes a Secret Test of Character to confirm that she can be trusted, the Monitor puts her in a time loop along with Oliver (whom the Monitor is trying to teach a lesson) so that she can make peace with Quentin's death.
- He actually brought Malefic J'onnz to give J'onn an oportunity to let go of his past.
- Physical God: He's capable of wiping out universes and is tremendously powerful.
- Promoted to Opening Titles: LaMonica Garrett gets upgraded to series regular for The Flash and Arrow, simultaneously.
- Reality Warper: He is capable of erasing universes.
- Reality-Writing Book: The Book of Destiny lets whoever holds it rewrite the world to their whims. The Monitor gives it to individuals on various Earths to cause chaos, seeing if the heroes would be able to stop them.
- Ret-Canon: While the Monitor has always existed, the name Mar Novu is a creation of the show, which too eventually made its way into the comics.
- Sarcasm Failure: Even the seemingly all-powerful and ever-collected Monitor is left speechless when he hears Lex Luthor unironically call himself a hero.
- Secret Test of Character:
- He offered to restore the destroyed Earth-2 if Laurel would betray Oliver. When she refused, the Monitor rewarded her (albeit in a characteristically odd way) by allowing her to come to terms with her surrogate father's death.
- Freeing Malefic from the Phantom Zone was a test for J'onn, to see if he could overcome his personal demons and prove himself a worthy champion to fight in the Crisis.
- Scary Black Man: A Physical God capable of wiping existence who has an appearance of an African human.
- Sink or Swim Mentor: The primary motive for his actions is to visit various Earths and subject their heroes to the Book of Destiny's reality-warping powers to see if they can overcome it, often resulting in massive casualties.
- Small Role, Big Impact: While he doesn't directly appear in the fifth season of Supergirl prior to the Crisis itself, his very act of rescuing Malefic from the Phantom Zone and bringing him to National City has a profound impact on the events of the season, as mentioned in Greater-Scope Villain above.
- The Stoic: Unemotional, patient, and composed at all times, Novu is the picture of godly detachment.
- Super-Reflexes: When Earth-90 Barry charges him, Novu casually flicks a finger and conjures a portal before Barry can do anything.
- Superhero Paradox: He unwitingly caused the Crisis by all his actions. His interest on going to the Dawn of Time leads to the creation of Mobius, while his morally ambiguous actions end up cauusing the Crisis.
- Thinking Up Portals: With a twitch of his finger, he can conjure portals from anywhere to anywhere, so quickly that he can portal away a speedster effortlessly.
- Unscrupulous Hero: He is willing to do morally dubious things to save the multiverse, like destroying universes or endangering alternate versions of Superman.
- Was Once a Man: 10,000 years ago, he was once a mortal time traveler who journeyed to the dawn of time.
- Well-Intentioned Extremist: He is creating chaos across the multiverse in the hope that heroes would arise and overcome it, because a threat even more powerful than him is coming; as such, if they can't stop him, the multiverse has no chance. Once the Anti-Monitor makes himself known, all of Novu's actions come off as justified compared to the threat that his nemesis poses to everything.
- Wowing Cthulhu:
- While he isn’t exactly easy to read, he seems to harbor a deep respect for Oliver in particular, as Oliver isn’t wowed by his godlike feats and treats him no differently than he would any other being, coupled with his bullheaded stubbornness to always be a hero, despite his claims that he isn’t. He tells Oliver with sincerity that he is sorry to inform him of his death in the Crisis, and the first time he actually seems to show emotion is when he is explaining Oliver’s apparent Heroic Sacrifice to the other heroes at the end of the first hour of the crossover.
- After Lois manages to prompt him into discussing his family (and show actual emotion as he does so), the Monitor takes a moment to be impressed at how capable a reporter she is.
- You Have Failed Me: When Earth-90 Barry Allen asks him why he's causing destruction, he simply responds with this trope.
Mobius / The Anti-Monitor
Species: Unknown (Antimatter clone of Mar Novu)
Played By: LaMonica Garrett
First Appearance: "A Mad Tea-Party" (Batwoman 1x8, voice), "Crisis on Infinite Earths, Part Two" (Batwoman 1x9, self)
Appearances: Batwoman | Supergirl | The Flash | Arrow | Crisis on Infinite Earthsnote
An Alternate Universe version of The Monitor from the Antimatter Universe.
- Adaptational Attractiveness: He's a grotesque version of his counterpart with a corpselike pallor, but at least he still looks basically human, whereas the comics Anti-Monitor was a grotesquely distorted suit of armor containing a roiling, shapeless energy cloud. This is because his appearance is more inspired in the New 52 version rather than the original one of Crisis on Infinite Earths, who does have a more human-like form.
- Advancing Wall of Doom: He destroys universes with a wave of antimatter that consumes everything it touches.
- Alternate Self: To the Monitor, being his antimatter counterpart.
- And I Must Scream: His final fate is being shrinked down and trapped in the Microverse.
- Arch-Enemy: To the Monitor. Everything Mar Novu does is in preparation for the Crisis and to oppose the Anti-Monitor, and he considers allowing Mobius to come into being at all to be his greatest failure.
- Anthropomorphic Personification: The closest thing we get to an explanation of who the Anti-Monitor is and why he does the things he does. Somehow, he is the Antimatter Universe — a humanoid personification of the negative universe's hunger to destroy all life and form and restore primordial chaos. When Mar Novu exposed himself to the Antimatter Universe at the dawn of time and thanks to his protective gear was not instantly destroyed, the Antimatter Universe stole his body and mind and was able to make a sapient avatar to enforce its will.
- Atrocious Alias: Cisco thinks the term "Anti-Monitor" is ridiculous. (Note that in the comics, both he and his counterpart just called themselves "The Monitor", and "Anti-Monitor" is only what he's called by the denizens of our universe.)
- Attack of the 50-Foot Whatever: Concept art has shown he's gigantic and towers over the heroes. His first encounter with Harbinger shows, however, that he can assume a normal humanoid height to interact with others. He grows gigantic in the final confrontation with the heroes.
- Badass Boast:
- His first on-screen speaking lines are him delivering one to Harbinger.Anti-Monitor: Universe after universe has fallen before my power. World after world, consumed. With every death, I steal my mirror's strength, while mine grows ever stronger. Who am I? I am the Anti-Monitor.
- Confronting the heroes for the first time prompts another one:Anti-Monitor: It is time to end the age of heroes and all you hold close.
- In the final battle, he keeps boastingAnti-Monitor: I am destiny incarnate, inexorable and inescapable. You are nothing. Insects fated to be crushed beneath my heel without a moment's thought. Fighting is useless. Surrender.
- His first on-screen speaking lines are him delivering one to Harbinger.
- The Bad Guy Wins: He actually did succeed in his Evil Plan to wipe out the Multiverse, with his victory lasting for a grand 6 months. The Spectre and the Paragons then have to undo his victory and bring the Multiverse back.
- Bald of Evil: Unlike the beard and strips of hair on the Monitor, the Anti-Monitor is totally bare-headed.
- Barrier Warrior: When he gets simultaneously attacked by all the Earth-Prime heroes, he activates a force field that completely negates all their attacks.
- Big Bad: Of Crisis on Infinite Earths and Arrow Season 8. The Crisis is also a looming presence with serious repercussions throughout The Flash Season 6, Supergirl Season 5, Legends of Tomorrow Season 5, and Batwoman Season 1, effectively making him a part of a Big Bad Ensemble for every season in Year Eight of the Arrowverse.
- Brought Down to Badass: Survives his initial destruction at the hands of Oliver, albeit in a weakened state. He is still powerful enough to casually fend off the collective assault of Earth's heroes and grow gigantic. He has to be shrunken down to a subatomic level to finally be dealt with.
- Composite Character: Has the role of the Anti-Monitor from the comic version of the events but has the true name of his New 52 counterpart. His status as the embodiment and avatar of the Netherverse who seeks to destroy the positive matter universe and all life is similar to Nekron, from the Blackest Night, who was the primal abyss given form and who sought to destroy all living things with his Black Lanterns.
- Contrasting Sequel Antagonist: In Elseworlds, Mar Novu in that the latter did what he did to test if the heroes could survive a someone more dangerous than him, while the Anti-Monitor actually wants to destroy all the multiverse.
- Cosmic Entity: He has the same powers as Mar Novu, and is stated by the latter to be far more powerful.
- Creepy Blue Eyes: He has very pale, watery blue eyes that bring to mind supernatural creatures in folklore.
- Dark Is Evil: The Anti-Monitor is a hideous and omnicidal antithesis of the Monitor that covers himself in dark armor and uses the nightmarish shadow demons as his army.
- Demonic Possession: In Hour Three of Crisis On Infinite Earths, he possesses Harbinger to attack the heroes and the Monitor directly. After he successfully restarts the antimatter wave, he seemingly discards the vessel afterwards, since the Harbinger is shown disintegrated along with the remaining survivors in the Waverider.
- The Dreaded: Everyone who fears the Crisis fears him, they just don't know it yet. Hell, even the Monitor is scared of him!
- Early-Bird Cameo: His voice could be heard throughout the final Arrowverse shows before the Crisis. The only one show he wasn't heard is Legends due to their Season premiere airing after the event.
- Evil Doppelgänger: The evil antimatter counterpart to our Monitor.
- Evil Gloating: After he is close to destroying the Multiverse, he smugly boasts about all of his plans and how the heroes are completely powerless to stop him.
- Evil Is Hammy: He could rival Thanos in this regard, with how much he loves to make dramatic Badass Boasts.
- Evil Sounds Deep: He speaks in the Monitor's already deep and powerful baritone, with the Anti-Monitor's voice lacking the hints of kindness that are present in his counterpart.
- Expy: Appearance-wise, he resembles Apocalypse.
- Facial Horror: His face is hideously deformed, making him look like a twisted, undead copy of the Monitor.
- Final Boss: Of Arrow. He is the last opponent Oliver Queen faces and ultimately has to sacrifice himself to stop.
- A God Am I: His goal is to obliterate the multiverse so that he can reign over the Antimatter Universe. Unlike many characters with this mentality, the Anti-Monitor has the power to back it up.
- Gravity Master: While possessing Harbinger, the Anti-Monitor demonstrates the ability to increase gravity to the point that even Kryptonians can't move.
- Greater-Scope Villain: Of the entire Arrowverse overall. The Anti-Monitor is a threat on a scale that dwarfs every other in the multiverse; everything the Monitor does is to oppose the Anti-Monitor and prevent his wholesale destruction of many universes.
- Hero Killer: The Anti-Monitor's multiversal rampage has destroyed countless worlds and slain countless heroes, but he truly earns this status by destroying Earth-38, with his legions of shadow demons mortally wounding Oliver in the process. He takes it a step further in Hour Three of the crossover, overpowering all of the heroes and the Monitor with ease, and successfully destroying Earth-1 and the Waverider, killing everyone except for six of the seven Paragons and Lex Luthor.
- Hidden Villain:
- While Team Flash and Team Arrow have been aware for a long time of the looming crisis, they may not even realize that there's an actual sapient entity that's causing it (were it not for a minor line by The Monitor during the second part of Elseworlds). Other than this line, he is never directly referenced prior to the crisis itself. However, this is only an In-Universe example, as promotional material has revealed him long before the pre-Crisis storylines, and anyone familiar with the source material would likely have guessed it even prior to that.
- Applies as well regarding his physical appearance. Even though he had destroyed dozens of universes beforehand, disregarding promotional pics, Mobius did not actually debut until Hour Two of the Crisis (Batwoman Season 1, Episode 9) and only as a cameo in the end.
- In Their Own Image: In destroying the multiverse, the Anti-Monitor intends to replace it with the Antimatter Universe so that he can rule over it.
- Jerkass Gods: While the Monitor is no paragon of virtue himself, the Anti-Monitor is infinitely worse, being a cruel, sadistic, and megalomaniacal Omnicidal Maniac who destroys universes so that he can rule over the Antimatter Universe as its sole deity.
- The Juggernaut:
- The antimatter wave he uses cannot be stopped, only delayed. The best efforts of the heroes only buys time for Earth-38's population to partially evacuate before the world is consumed and billions are killed. Even when the antimatter cannon that produces the wave is destroyed, the Anti-Monitor soon becomes powerful enough to recreate the wave himself, and it destroys Earth-1 unchallenged.
- The Anti-Monitor himself commands immense power that only grows as he destroys more worlds and saps power from the Monitor. Even when using Harbinger as a vessel rather than fighting himself, he proves capable of overpowering Superman of Earth-96 with ease, defeating the assembled heroes without breaking a sweat, and overwhelming the Monitor himself after a brief contest.
- Kick the Dog:
- After using Nash to free himself and instigate the Crisis, the Anti-Monitor turns him into Pariah, forcing Nash to watch the annihilation of the multiverse, powerless to stop the carnage.
- He uses Earth-90's Barry Allen as a power source for the antimatter cannon.
- Knight of Cerebus: The Crisis he instigates instantly darkens the tone of every story it impacts, with Crisis On Infinite Earths itself quickly becoming one of the darkest and most dire stories in the entire Arrowvere. Overall, he is by far the worst villain in the franchise.
- Light Is Not Good: The antimatter wave consumes Earths in a bright light and leaves a white void behind. Harbinger's eyes also glow white while the Anti-Monitor possesses her.
- Manipulative Bastard: He exploited Nash Wells' hatred for the Monitor in order to free himself.
- Meaningful Name: A Möbius strip is a two-dimensional surface that only has one side. The Multiverse once had "two sides", the positive matter universe of life and form and its chaotic, formless antimatter counterpart. Mobius the Anti-Monitor is the Antimatter Universe's desire given human shape to annihilate the positive matter side and be all that exists.
- Multiversal Conqueror: He has invaded and destroyed countless universes.
- Nigh-Invulnerable: The closest the franchise has ever come to the literal definition. He is in all respects unkillable and hence he does not end up dying. Instead he is defeated by trapping him in an eternally shrinking state where he won't be able to cause trouble for the Multiverse any longer.
- Offscreen Villainy: We don't see him destroy Earth-2 but we know he’s the cause.
- Omnicidal Maniac: His goal appears to be the destruction of the entire Multiverse, one universe at a time.
- The Omniscient: Another aspect that makes him particularly unsettling is he seems to know everything, no matter what time in history or version of the Multiverse it is. At the Dawn of Time he knew about the Paragons, how he was created from Mar Novu, and even how Oliver Queen was trained by Jim Corrigan. The version of him recreated on Earth-Prime in the new multiverse is also aware of his past defeat, greeting the Paragons again.
- Palette Swap:
- Has the same suit as Mar Novu but with darker colors and more muted.
- Mobius' bluish skin and light blue eye color are both inversion of Mar Novu's brownish skin and dark brown eye color, respectively.
- Physical God: He's even more powerful than the Monitor, being able to unleash a wave of antimatter capable of destroying the entire multiverse. At the height of his power, he can trigger the antimatter wave without any technology or outside help and obliterate the last of the multiverse.
- Power Parasite: As he destroys more and more worlds, the Anti-Monitor saps power from the Monitor. Confronting him while possessing Harbinger allows the Anti-Monitor to steal all of the Monitor's power, giving him the ability to restart the antimatter wave and effectively making him a god.
- Red Shirt Army: He commands an army of Shadow Demons. While each individual one are pretty much fodder that can be dispelled with a single attack, they are capable of overwhelming by sheer numbers.
- Ret-Gone: Averted. After many villains being dispatched in this way, he is thus far the only one shown to be immune to this. The Paragons try to prevent his creation by stopping Mar Novu from entering the Netherverse, but Mobius reveals that with an Infinite number of Mar Novus there will always be one to go through with it and bring life to him.
- Sadist: To "thank" Nash for freeing him, the Anti-Monitor turned him into Pariah and cursed him to bear witness to the Anti-Monitor ravaging the multiverse.
- Sealed Evil in a Can: He was originally sealed in a monolith, until Nash Wells destroyed it and freed him.
- Sliding Scale of Villain Threat: Hands down the most powerful threat of the entire Arrowverse, overtaking the likes of Zoom, Savitar, Mallus, Neron, and even Manny. The Anti-Monitor is a multiversal level threat and destroys entire universes and killing countless trillions on a whim.
- Spared by the Adaptation: From a certain point of view at least. The original event had him flat out killed in a Rasputinian Death sequence that culminated into him being punched into the sun by the Superman of Earth-2. He wouldn't be revived until decades after his death. In the Arrowverse, the Anti-Monitor is trapped in an And I Must Scream situation.
- Superhero Movie Villains Die: Averted. He might be the only character to be have Complete Immortality, in that there is no known way to kill him. So they do the next best thing, which is to trap him in an eternally shrinking state where he will no longer be able to influence the Multiverse.
- You Can't Fight Fate: As he proudly boasts, he is "destiny incarnate" and the one villain who is completely immune to being Ret-Gone. Even when the Paragons prevent one Mar Novu from creating his existence, another Mar Novu succumbs to ambition and inadvertently creates him instead.
- Voice of the Legion: He has a heavily distorted reverberating voice, to an even greater extent than Mar Novu.
- Worf Had the Flu: In the final hour of Crisis, he is defeated by a makeshift gizmo that shrinks him down into the Microverse, a far cry from the fact he had been able to No-Sell everything the heroes had thrown against him. It is justified, because, thanks to being defeated by Oliver, the Anti-Monitor hadn't reached his full potential, nor had he destroyed any universes in the multiverse. Though he probably would have tried again if he's not shrinking for eternity.
- Adaptational Distillation: The Spectre's status as the "Wrath of God" and a spirit binding to mortal host are left unexplained in this version. Here the Spectre is just a really powerful entity who is intune with The Multiverse with Reality Warper powers.
- Adaptational Modesty: Oliver's Spectre costume covers substantially more than the comics version, which amounted to a pair of speedos and a cloak. Here Oliver averts the Walking Shirtless Scene.
- Adaptational Wimp: Oliver as The Spectre while still impressive is nowhere near the scope of power Comics Spectre had, with Oliver mostly presented as a more standard reality warper as opposed to the near-omnipotent power of most versions of the Spectre. In addition, Comics Spectre managed to stalemate the Anti-Monitor, while here it costs Oliver his lifenote and the Anti-Monitor was ultimately not defeated (though he was severely weakened).
- All-Powerful Bystander: Oliver explains that the reason Spectres are rarely seen is because they are confined by rules and can only intervene when the entire Multiverse is being threatened.
- Color Motif: Green seems to be the color they are always associated with. It's the color of the Ghostly Glow they display and the color of Oliver's Spectre outfit.
- Decomposite Character: Played with. While there have been multiple Spectres in the comics, this is the first time the main Spectre isn't Jim Corrigan but instead Oliver Queen. Jim Corrigan is instead shown passing the mantle onto Oliver and serving as his mentor.
- Guardian of the Multiverse: Along with the Monitor, this seems to be their main role. To server as The Watcher and only step in when all else fails.
- In the Hood: It's unclear if this applies to Spectres in general or just Oliver, but a green hood is seen as part of his Spectre outfit.
- Necromancer: Oliver demonstrates the ability to return the recently deceased back to their bodies.
- Our Ghosts Are Different: They are said to be spirits, but they are not quite the same as usual ghosts either. They exist in a special form of resurrected life that is different from truly being alive but isn't dead either, but it is also possible to properly die while in this form. Oliver also creates a corporeal form for himself after his real mortal body no longer existed.
- Outside-Context Problem: To the Speed Force of all characters. Turns out the Spectre's powers do not mix well with the Speed Force which culminated in it ceasing to exist.
- Physical God: They are the closest thing we get, save for actual gods, being Reality Warpers who can match up to a multiverse destroying Cosmic Entity.
- Power Echoes: As the Spectre, Oliver's voice gains a reverb effect.
- Reality Warping: A somewhat limited one as examples of this goes, as while there's a lot they can do, they don't seem to be without restrictions on their powers. So far the feats they've displayed are: Teleportation across universes and time, manifesting a physical body on Earth, unlocking a speedster's powers to give them full access to the Speed Force, fighting on even ground against another Cosmic Entity, resurrecting the recently deceased, and the most impressive one being recreating a destroyed Multiverse (albeit with some assistance) after it got obliterated with antimatter.
- Summon Bigger Fish: Even the Monitor could not defeat the Anti-Monitor, so Oliver as the Spectre is brought in to finish the job.
Species: Human (Spirit)
Played By: Stephen Lobo
First Appearance: "Crisis on Infinite Earths, Part Three" (The Flash 6x9)
Appearances: Crisis On Infinite Earthsnote
Once a police officer, Jim Corrigan became a spectre. But now it is time for him to pass the mantle on to someone else.
- 11th-Hour Ranger: He shows up in Hour Three of Crisis On Infinite Earths just before the Darkest Hour to give Oliver the means of saving reality.
- Alternate Self: A different Jim Corrigan already appeared on Constantine, however Constantine notes that this is not the Jim Corrigan he knows.
- Ambiguous Situation: Given that Earth-1 Jim Corrigan is played by a different actor, along with the fact Oliver was in Purgatory that the heroes accessed from Earth-666. There is no indication what Earth this Jim Corrigan belongs to.
- Chooser Of The Chosen One: Chooses Oliver to be his successor as the Spectre.
- Ghostly Glow: His eyes glow green at times.
- The Mentor: Becomes Oliver's final mentor who teaches him the powers of the Spectre.
- Passing the Torch: He passes on the mantle of the Spectre to the recently deceased Oliver Queen.
- Teleportation: Seems to possess this power, able to teleport the mortals who entered into Purgatory back to the Waverrider (on another Earth).
Gods and Deities
- Adaptational Villainy: The Fates in both mythology and DC comics are typically neutral beings, here they are straight up villains, with the exception of Clotho.
- Ascended Extra: The Fates are very minor characters in the comics. Here, they are the focus of Season 5 of Legends of Tomorrow (and retroactively, Clotho has been a main character since Season 4).
- Big Bad: Atropos and Lachesis form a Big Bad Duumvirate for Legends of Tomorrow season 5. Clotho, the third Fate, is the White Sheep, and actually the Legend known as Charlie.
- Big Sister Bully: Charlie describes Lachesis and Atropos as having been this to her psychologically if not physically, always telling her what to do and trying to make her feel as if she'd be worthless without them, and Lachesis carries it over into being a manipulative Parental Substitute to Astra, whom she chose to be Clotho's replacement.
- Brought Down to Normal: After Clotho dismantles the Loom of Fate, they are left relatively powerless. This changes following Crisis On Infinite Earths where the Earths merging also causes the Loom pieces to coalesce on a single Earth, restoring the Fates' powers.
- Brown Note Being: True to Greek Mythology they have true forms that kill all mortals in their presence.
- Contrasting Sequel Antagonist: The first Arrowverse Big Bads to be actual deities from real-life mythology (specifically, Classical Mythology)note
- The Evils of Free Will: Their prime justification for seeking the Loom and using it to take back control over the fate of humanity, believing their free will has led to chaos.
- God in Human Form: They have taken on many faces throughout history, though their current forms seem to be stuck with them on a more longterm basis due to their being depowered by the loom's separation.
- Jerkass Gods: They wish to suppress free-will in mortals and don't care how many will die to achieve this.
- Motive Rant: Lachesis and Atropos give a few of these on The Evils of Free Will and how the mortals have chosen to abuse and tarnish the freedom of choice they have been given.
- Physical God: They are the three Moirai of Greek mythology, being the Fates who decides the lives of all mortals.
- Psychic Link: All three sisters have a psychic connection with each other, which they can use to telepathically communicate both willingly and unwillingly, while also feeling immense pain if one of them dies.
- Ring of Power: The Loom pieces take the forms of rings in order to be suitable for mortals gaze upon.
- Time Abyss: They are probably as old as the multiverse itself.
- Voluntary Shapeshifting: All of them are capable of shapeshifting, although for most of Season 4, Clotho is locked to Amaya's likeness.
- The Weird Sisters: The Moirai themselves, the three sisters who decided the fates of mankind.
- Well-Intentioned Extremist: They seem to genuinely believe humanity is better off without free will.
Played By: Sarah Strange
First Appearance: "A Head of Her Time" (Legends of Tomorrow 5x4)
Appearances: Legends of TomorrowThe oldest of the Fates, she was in charge of measuring the thread of life. Currently, she is living in Hell as the Coin Maker, guiding Astra Logue in her crusade against John Constantine.
- Big Bad Duumvirate: For season 5, along with her sister Atropos, though she is clearly the one in charge.
- Brains and Brawn: The brains to Atropos's brawn. While Atropos gets her hands dirty, Lachesis's specialty is scheming and manipulation.
- Brought Down to Normal: After the Loom is destroyed, Lachesis is permanently depowered and becomes mortal.
- The Corrupter: She's the one who has been pulling the strings on Astra, stoking the girl's hatred of John Constantine.
- Evil Mentor: She only helps Astra in her revenge against John so she can track down the Loom of Fate. In "The Great British Fake-Off", she outright manipulates Astra by posing as her to take some of the Encores to find the final piece of the Loom.
- Fallen-on-Hard-Times Job: For a former Goddess of Fate, making soul coins in Hell is clearly this.
- Faux Affably Evil: She's quite polite to those she talks to, as befitting a master manipulator.
- Fate Worse than Death: In-universe. Lachesis is proud of her power and status as a Fate, so getting turned into an ordinary human at the end of Season 5 must have felt like a fate (no pun intended) worse than death for her.
- God Was My Copilot: The Coin Maker's real identity is revealed four episodes after she debuts. However, Astra doesn't know her true identity until "The Great British Fake-Off".
- Greater-Scope Villain: Retroactively becomes one for Constantine's life, given Lachesis has Astra under her palm with Constantine's entire story being defined by his guilt on trapping her in Hell and trying to get her back.
- Humanity Ensues: After the Loom is destroyed, she and Charlie both turn into mortals.
- Karma Houdini: Despite all the suffering her actions brought, Charlie (instead of killing her) forgives her and urges her to try and give living a human life a shot.
- The Leader: As the oldest, Charlie refers to Lachesis as the leader of the Fates.
- The Man Behind the Man: She's the one manipulating Astra, the initial apparent Big Bad for Season 5.
- Manipulative Bitch: Groomed Astra into becoming villainous during her time in Hell, while appearing as a loving parent. If Astra ever starts expressing doubts, Lachesis is quite easily able to sway Astra back to her side.
- Parental Substitute: To Astra, whom she took under her wing in Hell and was planning to use to replace Clotho as the third Fate.
- Physical God: As one of the three Moirai.
- Satanic Archetype: If her residing in Hell wasn't enough of a clue, she invokes being a Fallen Angel by being a former deity who desires to retake the world that she believes is rightfully hers, and grooms Astra to be a successor through lies and temptations.
Played By: Joanna Vanderham
First Appearance: "Mortal Khanbat" (Legends of Tomorrow 5x5, voice), "Zari, Not Zari" (Legends of Tomorrow 5x8, self)
Appearances: Legends of TomorrowThe middle of the Fates, she was in charge of terminating the thread of life. Unlike Lachesis, she is more proactive in searching for the Loom, terrorizing the Legends who shelter Clotho and the Loom from them.
- An Arm and a Leg: Charlie cuts her hand with Genghis Khan's sword before sending her down to the time stream. It's regrown the next time she appears.
- Bad with the Bone: Her weapons of choice are daggers made of bone she pulls from her forearm.
- Beyond Redemption: A few Legends like Behrad and Gary try to reason with her after hearing she is Charlie’s sister, but Atropos remains undeterred in her murderous streak.
- Big Bad Duumvirate: For season 5, along with her sister Lachesis, though she acts more like The Dragon.
- Big Sister Bully: Charlie remembers her as being one, indicating a less than loving sisterly relationship.
- Brains and Brawn: The brawn to Lachesis's brains. She is very good at getting her hands dirty and killing people, while Lachesis tends to handle the manipulation.
- Creepy Monotone: Unlike Lachesis, Atropos speaks in a creepy emotionless tone, highlighting her nature as a cold-blooded killer.
- Devious Daggers: Prefers using her bone-shaped signature daggers to carry out kills, either through stabbing or throwing them at people.
- Dual Wielding: She brandishes two daggers in combat.
- Fantastic Racism: She is very derogatory towards mortals, referring to them as "vulgar" and is disgusted that Clotho has become one of them.
- Face of an Angel, Mind of a Demon: Has the appearance of a beautiful woman, but is a sadistic mass-murderer who is evil to the core.
- The Grim Reaper: The Greek Mythological equivalent. Being the Fate in charge of cutting the thread to end a person's life.
- Hero Killer: In her first appearance she kills Charlie's band-mates and by the end of the episode she kills Behrad, while the heroes don't stand a chance against her. Oh, but it gets worse. In her next major appearance, she summons a Zombie Apocalypse upon London that ultimately kills Sara, Ava, Nate, Zari, Mick, and Constantine while she herself kills both Astra and Gary with her bone knives.
- The Juggernaut: Given that she's a Physical God, little to nothing can harm her, while she in turns brings mass death and destruction in her wake.
- Improbable Aiming Skills: She has exceptional precision with her knives, pulling off successful kills with each throw.
- Karmic Death: She dies by being dragged into the Loom, the very artifact she and her sister committed several atrocities for to find, seconds before it's destroyed in an explosion.
- Knight of Cerebus: When she first makes her debut midway through season 5 she makes the tone drastically darker. She starts by killing Charlie's former bandmates, and appears to be an unstoppable force of nature that will get the Loom of Fate by any means. In the episode's climax she even kills Behrad.
- Murder Is the Best Solution: If there is any perceived problem, her first reaction is to brutally kill it. She suggests killing Astra once she had outlived her usefulness, but Lachesis talks her out of it.
- No-Sell: She shrugs off being stabbed by Genghis's sword, which normally disintegrates people to oblivion. That said, the sword is still capable of injuring her, as Charlie cuts her hand with it, although the hand disappears and possibly reattaches itself with her afterwards.
- No Social Skills: In stark contrast to her sister, she is unable to put any kind of friendly facade whatsoever. She always has a blank stare and speaks extremely bluntly.
- Not So Stoic: While usually cold and robotic, she screams in pain as she is killed.
- Not-So-Well-Intentioned Extremist: While Atropos spouts the same Motive Rants as Lachesis on The Evils of Free Will, Charlie reveals that Atropos always enjoyed killing even during her time as a proper god, and her Fantastic Racism attitude shows she cares nothing about the well-being of mortals. For Atropos, it's less about wanting to remove free will for the good of humanity, and more that Atropos just hates seeing rebellion and individualism from these lesser creatures. This is cemented in "Loomworld" where she forces her "Historical Sanitation Department" to scrub history's records clean of any signs of rebellion.
- Perpetual Frowner: She never smiles, always bearing a cold frown on her face.
- Physical God: As one of the three Moirai.
- Psycho Knife Nut: An expert killer who has a penchant for her special bone knives that she uses to massacre.
- Sadist: While it's hard to tell due to her lack of facial expression, Charlie/Clotho affirms that Atropos took great pleasure in every life she ended.
- The Sociopath: Cold, emotionless, unable to form attachments, and takes great enjoyment in killing.
- Soft-Spoken Sadist: She never raise her voice or changes her tone as she goes about her killings, but Charlie makes it clear she is a sadist who thoroughly enjoys killing.
- Strong and Skilled: Both an immortal Physical God and a skilled hand-to-hand fighter. Atropos is near-impossible to beat in a one-on-one battle unless one resorts to cheating.
- Superpower Lottery: Super-Strength, Nigh-Invulnerability, Time Travel, the ability to easily go to and from Hell, necromancy, shapeshifting, and the ability to kill people in two unique ways (in addition to her standard strength and weaponry, both of which are more than enough on their own): by revealing her true form, and by undoing the cheating of death (e.g. by time travel) by severing their chain of fate. Yeah, she's a deity all right.
- There Is No Kill Like Overkill: Atropos is instructed by Lachesis to stall the Legends. What does Atropos do? Trigger a Zombie Apocalypse that ravages all of Great Britain and killing millions, just to take out seven measly Legends.
- Too Powerful to Live: Being a sociopathic god who is beyond reasoning, the Legends are left with no choice but to kill her off to end her threat, despite her being Charlie's sister.
- Villainous Breakdown: The usually stoic, unshakeable Atropos, screams in agony when she gets killed by the Loom being destroyed.
- Vile Villain, Saccharine Show: Atropos is one of the darkest villains to date on an otherwise usually quite lighthearted show.
- Violent Glaswegian: She speaks in Joanna Vanderham's natural Scottish accent, and is a cold-blooded killer who leaves a trail of bodies wherever she goes.
- You Cannot Grasp the True Form: In "Zari, Not Zari", she demonstrates her real form twice, the first time killing the last surviving Smell bandmate. The second time, however, she is unable to kill Sara for unknown reasons.
- You Can't Fight Fate: Her name is literally Ancient Greek for "the inevitable". Upon realizing that Behrad basically cheated death by switching places with Zari during the events of "Hey, World!", she pulls his chain of fate and cuts it, killing him.

- In-Series Nickname: His mortal name is “Dion”.
- Really 700 Years Old: While not quite as old as the Fates, being a child of Zeus and born a fair bit later than him. He is still at least thousands of years old.

- Bad Guys Do the Dirty Work: They are the ones who drag Nyxlygsptlnz and Lex into the Phantom Zone in the Series Finale.

- Healing Factor: Physical injuries are of minor concern to them, as they heal almost instantly.
- No Ontological Inertia: Destroying the Phantom chrysalis returns all the lost souls to their owners and undoes their Phantom transformations.
- The Soulless: Since they turn people into Phantoms by stealing their souls, obviously they don't have them.

Unknown / Other
Played By: Darren Criss
First Appearance: "Star-Crossed" (Supergirl 2x16)
A mysterious being playing as a villain who was on Earth-38 before he manages to escape to Earth-1. Manages to put both Supergirl and the Flash under his hypnotic spell.
- Adaptational Abomination: The Batman: The Brave and the Bold version was a human who happened to have his trademark The Music Meister power. This version of the Music Meister is an Eldritch Abomination with seemingly limitless Reality Warper powers.
- Adaptational Badass: The Batman: The Brave and the Bold Music Meister could only hypnotize victims into doing his dirty work, but didn't have much in the way of direct combat. While this Music Meister is a borderline Reality Warper with a wide array of impressive powers, including draining the powers of his victims.
- Adaptational Dye-Job: In Batman: The Brave and the Bold he was a carrot top, while Darren Criss has black hair.
- Adaptational Heroism: He put Kara and Barry under his spell as a Secret Test of Character rather than out of malice, as opposed to the original Music Meister, a Card-Carrying Villain who, despite having a sympathetic origin, had no empathy and was really only out to get rich.
- Adaptational Superpower Change: The original Music Meister put his victims into a hypnotic trance where they would sing and be under mind control. This Music Meister induces a coma in his victims, where they enter a shared dream world where their powers are removed and they must fulfill certain conditions (sing in a musical in Barry and Kara's case) in order to escape. He also acquires the powers of those under his spell.
- Affably Evil: During the entire crossover he's very friendly and cheerful to everyone. It makes sense once it turns out he isn't that evil.
- Alliterative Name: Music Meister.
- Ambiguously Evil: Ultimately, his reason for trapping Kara and Barry in the dream world was to get them to repair their relationships with Mon-El and Iris. However, he seemed unconcerned about the possibility of them getting killed within it.
- Ambiguously Human: His exact nature is unclear. While he might look human, his abilities and his statements of the heroes not being able to comprehend what he is, suggest he's something else altogether.
- Ambiguous Situation: It's unclear just how he managed to end up on Earth-38, since he apparently can't actually travel between Universes.
- Arc Villain: Of the 2017 crossover between Supergirl and The Flash
- Blue-and-Orange Morality: The Music Meister traps Barry and Kara in a dream world where they could potentially be killed and steals their powers so he can rob a bank. The reason he put everyone through this was to teach Barry and Kara the importance of love, and as a side benefit help Wally get his confidence back. Once they learn the lesson and wake up, he's satisfied that his work is done and leaves to teach someone else a lesson.
- Canon Immigrant: Technically. He debuted on Batman: The Brave and the Bold before making his way onto CW's Arrowverse, but he has yet to make an appearance in the source material.
- Captured on Purpose: He allows himself to be captured by the D.E.O. so that he can snatch the inter-dimensional transporter and escape to Earth-1. He later effortlessly breaks out the Pipeline at S.T.A.R. Labs.
- Casting Gag: Played by Grant Gustin & Melissa Benoist's former coworker.
- Civvie Spandex: This Music Meister dresses in mostly normal looking clothes, unlike his Batman: The Brave and the Bold counterpart who has a notorious habit of frequently changing outfits.
- Composite Character: His god-like powers and prankster nature make him more like Mr. Mxyzptlk.
- Early-Bird Cameo: He's mentioned in the possible future visited by Barry before appearing in person in the crossover.
- Evil Is Hammy: He's very theatrical and cheeky, much like his animated counterpart.
- Evil Wears Black: Music Meister dresses in various shades of black, save a red handkerchief.
- Good All Along: Ultimately, the reason he did everything was to help the heroes deal with their personal problems.
- Great Gazoo: Shows up out of nowhere to teach Kara and Barry a lesson, and then vanishes without explaining who or what he is.
- Humanoid Abomination: He has a long list of reality defying powers and says that the heroes wouldn't even understand where he's from or what he is.
- Hypnotic Eyes: He can send people into a coma. When he does his eyes flash.
- Inexplicably Awesome: He refuses to explain what he is.
- In Name Only: He shares virtually no common traits with the original Music Meister; in fact, he seems to take more after Mr. Mxyzptlk than his namesake.
- Lotus-Eater Machine: He sends Kara and Barry into a musical film fantasy.
- Magic Eye: His eyes possess the ability to send people into a coma.
- Medium Awareness: He claims to be aware of everything, and does have knowledge of cultures throughout The Multiverse.
- Movie Superheroes Wear Black: His animated counterpart had multiple costumes colored green and purple. Here, he wears a black suit.
- Musical World Hypotheses: His comatose victims are placed into a shared dream, where they must fulfill certain conditions in order to escape. In "Duet" he places Kara and Barry into a musical film scenario coincidentally informed by their fond memories of the genre.
- The Music Meister: In a different way to the Trope Namer who he's based off. This Music Meister sends his victims into a coma where they end up in a shared dream, and the only way to escape is to fulfill certain conditions (in Barry and Kara's case, singing).
- Mysterious Past: Nothing is known about what he is, or where he's from, and he refuses to shed any light on these questions.
- Nice Guy: While he's a Sink or Swim Mentor with enigmatic motives, he's a Shipper on Deck for Barry and Iris, and Kara and Mon-El, as well as telling Wally that he's a big fan.
- He also seems to genuinely enjoy the chance to sing and dance with the other characters in Barry and Kara's dream-state, and speaks kindly to them and to Wally.
- The Omniscient: He's aware of what's happening to characters on both Earths-1 and 38, implying he's also aware of the entire Multiverse.
- Power Nullifier: While in the Music Meister's coma, superheroes will have lost their powers.
- Power Parasite: Somehow, he was able to drain Kara and Barry's powers through their dream-state. Whether or not it's permanent for him is never stated.
- Reality Warper: He displays the ability to teleport, and is implied to be a 5th-Dimension Imp like Mr. Mxyzptlk (or something else entirely).
- Rogues' Gallery Transplant: In his initial appearance on Batman: The Brave and the Bold, he was a Batman villain.
- Shipper on Deck: He plays Cupid for Barry & Iris and Kara & Mon-El. Why? Who knows?
- The Spook: While he is indeed very powerful, as he managed to steal Barry and Kara's powers and even escaped from the Pipeline, almost nothing else is known about him.
- Super Power Lottery: This Music Meister displays an impressive array of powers. In addition to his traditional music inducing hypnotism, he's also a Power Parasite, a Power Nullifier, displays Medium Awareness, and uses teleportation.
- Tall, Dark, and Snarky: As played by Darren Criss, he's pretty cheeky when he escapes to Earth-1.
Species: Ancient cosmic entity
Played By: Robbie Amell
First Appearance: "The Fire Next Time" (The Flash 8x8)
Appearances: The Flash (2014)
An ancient cosmic malevolent force made up of cold fusion that gained a form upon Ronnie Raymond's death in the singularity and spent the next seven years travelling across the cosmos trying to find Caitlin, the love of his host body's life.
- Ancient Evil: It's extremely evil and it claims to be older than the stars itself.
- Arc Villain: Appears as the main antagonist for a number of episodes in the middle of season 8.
- Bishōnen Line: He initially appears as a swirling mass of black fire with a skull face in the centre. After he tricks Caitlin and Frost into giving him the quantum splicer, he adopts a more humanoid appearance.
- Blue Is Heroic: Inverted. It's blue and black and very, very evil.
- Canon Character All Along: It's eventually revealed to be Deathstorm, similar to his appearance in Blackest Night.
- Composite Character: It takes Nekron's spot as the mastermind behind the return of deceased heroes and allies, though Deathstorm does so via illusions rather than actual reanimations of the dead.
- Dead Person Impersonation: It can take the form of deceased loved ones that are close to those whom it haunts and tries to kill, to get them to give into their grief beforehand. Additionally, in its true form it is possessing the body of Ronnie Raymond following his death in the singularity, and initially pretends to be him to trick Caitlin into giving him the quantum splicer.
- Eldritch Abomination: It's an ancient, cosmic force of evil that lacks a true original form and feeds on death and grief. It then took over Ronnie's body after he perished in the Singularity, and then using the mental remnants from his body travelled the cosmos for seven years trying to find Caitlin to try and make her his Deathstorm bride. Nothing else in the Arrowverse comes even close to matching a description like that.
- Emotion Eater: Grief makes it stronger, and its victims tend to be those who are grieving.
- Evil Counterpart: Built up as one to Frost, with both of them having a blue coloration. Only now he's the evil Firestorm to contrast her now good Killer Frost. It is ultimately Frost who defeats him and is treated as Frost's personal enemy.
- Evil Living Flames: He initially appears as a mass of black fire that Team Flash initially thinks is being activated by a metahuman, before they realize that the fire itself is alive.
- Evil Twin: Invoked. Deathstorm specifically stole the form of Ronnie Raymond upon his death, with the entity finally able to take physical form.
- Flying Firepower: After gaining a humanoid form he gains a powerset similar to Firestorm.
- In Name Only: It's initially described as a "Black Flame", but there actually is a DC character with the name Black Flame: Zora Vi-Lar. This thing has nothing to do with that.
- Kick the Dog: As "Eddie", he offers to make Iris some soup from his uncle Robern's place for seemingly no reason except to twist the knife about Thawne tricking Iris into an engagement party there.
- Kill It with Fire: Its victims are burned to a crisp with its blue fire, leaving behind only a charred skeleton.
- Knight of Cerebus: His appearance marks a shift in tone from superhero fiction into outright horror, something Eric Wallace specifically noted.
- No-Sell: Nothing that Team Flash uses against him has any effect whatsoever. He's ultimately defeated after Frost is empowered in the M.A.C. device so that she effectively becomes an anti-Deathstorm living weapon.
- Obviously Evil: Let's see, it has a flaming Skull for a Head, has a dark color aesthetic, is fueled by grief, and has "Death" in its name. Yeah, we've got our villain.
- Outside-Genre Foe: Team Flash usually comes into conflict with other metahumans, whereas the kind of ancient cosmic entity that Deathstorm represents is usually the kind of beast that would be fought by them only in an annual crossover or something. In fact, it was initially assumed that his initial murders were committed by an actual known fire metahuman, and when his name was cleared, they assumed it was another metahuman, before realizing they're dealing with something else entirely.
- Serkis Folk: Both his ethereal form and his humanoid form are created with CGI (the latter possibly using motion capture on Robbie Amell or a stunt actor). That said, he occasionally chooses the form of Ronnie exactly.
- Stalker with a Crush: Its goal is to use as much grief energy as possible from its victims to tranform Caitlin into a being resembling himself to be his eternal bride, a goal it manifested after coming into contact with Ronnie's body.
- Technicolor Fire: Its fire is black and blue rather than red, and is said to be a product of cold fusion.
- Truer to the Text: This Deathstorm has a lot in common with his appearance in Blackest Night (which is itself referenced twice in the arc), compared to Firestorm's Earth-2 counterpart who called himself "Deathstorm" seen back in season 2. Though it should be noted that the previous Deathstorm was based on the New 52 version who was an evil alternate counterpart of Firestorm from Earth-3.
The Ionosphere Entity / JJ Stewart / "Jennifer Pierce"
Species: Energy Being
Played By: Laura Kariuki
First Appearance: "The Book of Ruin: Chapter One: Picking Up the Pieces" (Black Lightning 4x5)
Appearances: Black Lightning (2018)
A being from the Ionosphere, the place Jennifer Pierce frequently visits to boost her powers, which eventually entraps Jennifer and tries to take her place in a new body.
- Becoming the Mask: While what she does is unforgivable, she seems to genuinely enjoy being a hero and a part of the Pierce family.
- Big Little Sister: Everybody notices how "Jennifer" is a whole lot bigger than before.
- Bitch in Sheep's Clothing: Tries to replace Jennifer and take over her life, acting vulnerable and nice towards the Pierce family.
- Heroic Rematch: While she initially loses to Red, after boosting her powers and being pissed about Uriah's death, she makes short work of him.
- No Body Left Behind: Jennifer absorbs her entire essence into herself.
- Pretending to Be One's Own Relative: Introduces herself at Garfield's as Jennifer's cousin, JJ.
- Ship Tease: She and her schoolmate Uriah take a liking to each other. Unfortunately, the latter gets murdered by Red.
- Sympathy for the Devil: Jennifer feels sorry for her, as she always wanted to experience how it was to live among humans and to have a family, but points out that that doesn't give her the right to steal her life.
