The Speed Force is the sentient extra-dimensional source of Barry Allen and all speedsters' powers and the key to honing in on their ability to affect the fabric of reality. \\\

When Oliver Queen - the new Spectre - allowed Barry to access the Speed Force after the Multiverse was destroyed, it was poisoned by the cosmic energy and would later die. [[spoiler:Team Flash would work towards reviving it, but in the process, also create the Forces of Nature: the Strength Force, the Sage Force, and the Still Force. Recovering from their attack, the Speed Force comes to Barry and his friends for aid against them.]]\\\

-> see the Characters/ArrowverseTeamFlash page for [[spoiler:its human form]]

* AboveGoodAndEvil: The Speed Force isn't bothered whether a speedster is "good" or "evil". They'll only terrorize the speedster if the speedster pisses them off.
* AccuserOfTheBrethren: In Season Three, it's really pissed off at Barry for creating Flashpoint, not really caring about his guilt or his efforts to atone, and resolves to BeAsUnhelpfulAsPossible in retaliation. In the finale, it forces Barry into an early retirement by making him occupy Savitar's prison to stabilize the Speed Force's energy, though it claims it won't be the hellish experience for Barry that it was for Savitar, Wally, and Jay.
* AccompliceByInaction: It did not stop the Reverse-Flash or Zoom when they killed Barry's parents.
* AchillesHeel: It needs a speedster to occupy the prison Barry made for Savitar inside of it. Otherwise, it becomes unstable and will start damaging the physical world.
* AllPowerfulBystander:
** It could easily help Barry by cutting off the connection of the evil speedsters he faces and yet it refuses to do so -- it only did it once and that was ''after'' Eobard killed Nora.
** It admits to Barry it could've stopped Flashpoint from happening, but allowed it to happen just so Barry could learn the consequences of abusing his powers -- no matter the personal collateral damage to Team Flash.
** In Season Three, Savitar is imprisoned in it, but it doesn't do much to keep him in. In fact, it invests much more energy into keeping Wally and later Jay imprisoned in Savitar's place.
* BackForTheDead: The Speed Force as Nora appears again in "Death of the Speed Force" in a dying state. It was revealed [[NoGoodDeedGoesUnpunished Barry accidentally damaged it when he had Oliver make him reach his full potential to restore the multiverse]].
* BackFromTheDead: [[spoiler: The Speed Force is brought back to life in The Flash 7x03.]]
* BlueAndOrangeMorality:
** It doesn't distinguish between good and evil speedsters accessing its powers, although it will cut them off if they cross certain lines, but it will be exceptionally harsh to any good speedster who fails to live up to its very high standards.
** Eobard Thawne went back in time and ended up killed Nora and the real Harrison Wells, amongst others and meddled with events for his own ends. Yet when Barry goes back in time to save his mom, the Speed Force seems more outraged for Barry having a moment of weakness than the unrepentant actions of a cold-blooded murderer.
** It scolds Barry for giving his speed to Zoom, even though he did it to save Wally's life, something Barry lampshades.
** It doesn't seem to understand why the MiseryBuildsCharacter aesop it tried to teach Barry would fail to stick when Henry was killed only a few days after - especially when was in similar circumstances to Nora's murder.
* TheChooserOfTheOne: The Speed Force chose Barry to be the Flash. It also forces him into an early retirement in the Season Three finale because the Speed Force will collapse in on itself without an occupant in the prison Barry made for Savitar, and it decides that Barry should be the one to occupy it.
* ComboPlatterPowers: The Speed Force can bestow SuperSpeed and all the powers that come with it upon humans, see the full course of time and space, cast illusions, and even simulate the effects of Leonard Snart's Cold Gun.
* DeadPersonImpersonation: It has projected itself using four deceased people that Barry knew, namely: Nora Allen, Eddie Thawne, Ronnie Raymond, and Leonard Snart.
* EarlyBirdCameo: It is the bolt of lightning that struck Barry during the night he got his powers -- over two years before its existence is officially confirmed.
* AFormYouAreComfortableWith: The Speed Force manifests as people close to Barry and locations Barry knows. As of season 6, it appears to default to his late mother, Nora.
* GodInHumanForm: [[spoiler:It appears before Team Flash in the aforementioned human form in season 7, asking for their help when it becomes overpowered by the Forces of Nature created after its resurrection.]]
* GodIsDead: When the Spectre bestows a tremendous boost of power to Barry to enter the Speed Force after the Anti-Monitor destroyed all known existence, the cosmic energy is not only powerful enough to ''poison'' the Speed Force, but ''kills it'' in a matter of weeks. This leaves Barry and other speedsters with reserve speed power that'll be gone forever unless they find an alternative. [[spoiler: Season 7 has Team Flash managing to bring it back to life.]]
* GodIsFlawed: For all its omnipotent and mysterious plannings, the Speed Force never takes into account the emotional turmoil it puts on Berry and cares very little for the tragedy his life, all calming that it's necessary for TheNeedsOfTheMany. It reaches it's breaking point when Berry has finally had enough and calls the Speed Force out on everything it has ever done. It ends up rendering the Speed Force to ''tears''.
* IWillPunishYourFriendForYourFailure: It deliberately goes out its way to make Barry's loved ones be the ones who suffer most when he misuses his power.
* InMysteriousWays: It's been ''implied'' to do this, in any case. The motivation behind Eddie Thawne's HeroicSuicide was his adamant belief that ThereAreNoCoincidences, and despite whatever Eobard Thawne espoused to Barry, his actions during Season 1 were damaging to the timeline. It's all but stated that the Speed Force let Eobard run amok because it knew his actions would eventually lead to Eddie killing himself to stop him, erasing Eobard from existence.... which backfired ''spectacularly'' since by waiting so long to deal with Thawne, it created a villain who will simply ''not'' die.
* JerkassGods: The Speed Force can get really nasty when it's angered. It's also not above with playing with the fates of Barry's loved ones just to teach him a lesson -- it let Zoom get away with killing Henry just to see if Barry really did learn how to cope with tragedy.
* KickTheDog: For some reason, it ''really'' doesn't like Wally West, with it's treatment of him in "Into the Speed Force" being just plain cruel. It seems to be on better terms with Wally in "Death of the Speed Force" after gaining a spiritual connection to it.
* LoveIsAWeakness: It doesn't ''outright'' state it believes this, but considering it keeps turning a blind eye whenever evil speedsters kill Barry's loved ones and generally NoSympathy to Barry's grief you have to wonder...
* MiseryBuildsCharacter: It tries to get Barry to see that just because he's a hero, he's not immune to tragedy. Unfortunately, it chose to do this just a couple of days before Zoom killed Henry, which ''broke'' poor Barry.
* NeverMyFault: It condemns Barry for creating Flashpoint, even though it didn't stop Zoom from killing Henry and putting Barry in the state of mind to do so.
* NoSympathy: The Speed Force is way too detached from humanity as it doesn't seem to understand or care about the grief or suffering of others; it understands that personal loss is something to be mourned but it doesn't seem to understand just how devastating it can be. Probably justified in that, as an omniscient SentientCosmicForce, [[WeAreAsMayflies the lives, deaths, and emotions of individual humans are hard for it to comprehend.]] Eventually, [[WhatTheHellHero Barry gets fed up with it and calls it out on everything it's done]].
* NotQuiteDead: [[spoiler: It's revealed that due to her connection with Barry, Iris carried a spark of the Speed Force after it was gone. This was enough to allow Team Flash to bring it back.]]
* NotSoStoic: The Speed Force becomes emotional for the first time as Barry calls out on everything it has ever done to both him and his loved ones. It can't come with a retort, because it knows he's right.
* TheOmniscient: The Speed Force is aware of ''everything'' that is happening, from the different {{Alternate Timeline}}s to every part of TheMultiverse.
* OmniscientMoralityLicense: All the Speed Force cares about is keeping things "just", regardless of the expense it will take on other living souls.
* PlaceBeyondTime: The Speed Force seems to be this, as it was not only aware of the Flashpoint timeline, but also of Leonard Snart's HeroicSacrifice which took place at the Vanishing Point which is outside of time.
* ThePowersThatBe: It works in ''very'' mysterious ways. It saw fit to strip Eobard Thawne of his powers after he killed Nora, but it didn't do anything to stop Zoom despite all of the mindless carnage he caused, other than sending Time Wraiths after him.
* RoyalWe: It always refers to itself as "we" when talking to Barry, probably because it uses multiple avatars to do so.
* SecretTestOfCharacter:
** The whole point of the Speed Force trapping Barry in "The Run Away Dinosaur".
** It's implied that it let Zoom kill Henry to see if Barry truly learned how to cope with tragedy.
** Savitar killing Iris is implied to be yet ''another'' test.
* SentientCosmicForce: The Speed Force is demonstrated to be sentient when it speaks directly to Barry through avatars of people he loves. The Speed Force even gives him a What the Hell, Hero? speech for giving up his speed in exchange for a single life, when he could have used it to save many more lives. Also, the only way the Speed Force will give him his speed back is if he comes to term with his mother's death.
-->'''Barry:''' I'm ''talking'' to the Speed Force? Isn't that like saying I'm having a conversation with gravity, or light, or...
* SoProudOfYou: It admits to being proud of Barry.
* SternTeacher:
** Sent a Time Wraith after Barry the first time he misused his powers in "Flash Back". Unfortunately, Barry didn't take the hint.
** It's much harder on Barry in "Into The Speed Force" because it's mad that Barry created Flashpoint - it let it happen just so Barry could see the consequences of his actions.
* TimeAbyss: The Speed Force is at least as old as the universe itself, and will last at least that long as well.
-->'''Speed Force:''' When the first subatomic particle sprang forth from the Big Bang to form reality as you know it, we were there. When the last proton decays, stops vibrating, and plunges the universe into heat death, we'll be there too.
* {{Ubermensch}}: The Speed Force has a set of morality and standards exclusive to itself.
* TheWorfEffect: [[spoiler: Season 7 has it become severely beaten by similar forces that were created upon its revival.]]
* WarriorTherapist: The Speed Force is apparently one. On both visits, Barry spends the entirety of his time in it resolving his issues. However it tends to not be very effective due to it's BlueAndOrangeMorality and NoSympathy attitude.

!!! '''Appearances:''' ''Series/{{The Flash|2014}}''

The Speed Force's temporal agents, horrifying creatures that hunt speedsters that alter the timeline.

* AmbiguousSituation: How they act is a bit enigmatic. Eobard Thawne implies that they only appear under certain circumstances and that just trying to alter time isn't enough to cause their presence but on the other hand makes a few comments that it was just chance that Barry ran into one and gained its attention. Though it's implied the Speed Force itself sent it after Barry.
* ChekhovsGunman: Initially appearing as a VillainOfTheWeek, they return in the Season Two finale and prove instrumental in finally beating Zoom.
* ClockRoaches: Speedster messing with the timeline too much? These guys will take care of the anomaly.
* CoDragons: They are the Speed Force's most loyal enforcers.
* DarkIsNotEvil: At their core, they just want time to not be torn apart by paradoxes-the ones who show up to investigate the HeroicSacrifice of Barry's time remnant ignore Barry in favor of Zoom, presumably because they recognized he did that paradox to save the multiverse.
* DraggedOffToHell: It's revealed this is basically what they do to their victims when they do it to Zoom after his defeat.
* TheDreaded: Even Eobard Thawne is scared witless of these guys. Seeing what they did to Zoom when they found him, it easy to see why.
* {{Expy}}: Of [[Franchise/HarryPotter Dementors]], as [[LampshadeHanging lampshaded]] repeatedly by Cisco and Hartley.
* HumanoidAbomination: They look like Dementors and freely inhabit, and travel through, time itself.
* ImmuneToBullets: The police fired countless rounds into the wraith without harm. The Time Wraiths may even be NighInvulnerable, as Eobard mentions that no one, even in the future, has found a way to stop them.
* LongBusTrip: They have not returned ever since Wally was rescued from the Speed Force in Season 3, until "What's Past is Present".
* ManOfKryptonite: Any one of them can "eat" Barry's speed and immobilize him.
* NotSoInvincibleAfterAll: Most attacks are useless against them, but Hartley discovers that they can be destroyed by low frequency sound.
* OurGhostsAreDifferent: In their case, they're ClockRoaches "employed" by [[ThePowersThatBe The Speed Force]].
* OutsideGenreFoe: A race of ghost-like, supernatural entities that exist in the time stream would fit more with a show like ''Series/DoctorWho'' than ''The Flash''.
* SuperSpeed: One of them can easily keep up with the Flash and even Eobard Thawne doesn't think he could shake them.
* SuperStrength: Oh yes. Just one of them was able to start breaking into a containment cell in the particle accelerator in order to get to Caitlin, Cisco, and Hartley. Even ''Girder'' was unable to even dent such a cell, so the Time Wraiths clearly have a formidable level of strength.
* SuspiciouslySimilarSubstitute: Their decayed appearance evokes the comics' Black Flash, the Grim Reaper of all speedsters. After what they did to Hunter Zolomon, they seem to be the Black Flash's predecessors in this continuity.
* WeaksauceWeakness: Low-frequency sound is fatal to them, as the Time Wraith attacking Barry finds out.

->"''The Flash pulled me from the timeline. He held me captive for months and when I finally got loose, I found myself pursued by something. I..I thought it was a time wraith, the monsters that hunt speedsters who mess with time. But whatever is hunting me is far worse than a time wraith. It can sense the Speed Force. And it's trying to kill me!''"
->--'''Eobard Thawne'''


TheGrimReaper of speedsters. The Time Wraiths' personal wetworks agent, the creature sent in when a speedster's abuse of time is so extreme that the Wraiths themselves are concerned to get involved. It wears a black version of the Flash's suit, which covers its entire body like a cancerous growth, and has a NightmareFace which appears half disintegrated.

The Black Flash is the "devolved" form of Earth-2's Hunter Zolomon, the BigBad of ''The Flash'' Season Two.

-> See Characters/ArrowverseHunterZolomon page for tropes relating to his previous self.
-> see Characters/SmallvilleOtherMajorVillains page for the Earth-167 character who bears its name and background

* AchillesHeel: Being frozen solid is enough to at least temporarily destroy him. It's implied that this isn't a permanent solution, however (the Black Flash was seemingly destroyed before, but returned nonetheless).
* AdaptationalSpeciesChange: The Black Flash in the comics was allegedly some kind of supernatural entity, being the speedster equivalent of TheGrimReaper. Here, he was once the metahuman speedster known as Hunter Zolomon before being turned into the Black Flash by the Time Wraiths.
* AllThereInTheManual: InUniverse, the name "Black Flash" is never spoken or referred to by any of the characters. Eobard usually refers to him as "that thing", and Barry calls him by the name he had when he was a human: Hunter Zolomon. Finally averted in ''The Flash'' Season Three finale, when Savitar explicitly refers to him as "Black Flash".
* AndIMustScream: He's stuck in a decaying body and forced to serve as the enforcer for the Time Wraiths and there are hints that his mind is at least partially still functioning, making his fate this trope.
* ArrowCatch: He pulls this on Merlyn.
* BadassInDistress: In "Doomworld", Thawne manages to trap him in a cell with the Spear of Destiny. However, in "Aruba", Sara depowers the Spear and sets him free, (or rather prevents him from being imprisoned) allowing him to finish his mission of killing Thawne.
* BeCarefulWhatYouWishFor: When Zoom wanted to become more powerful and stave off death, becoming an undead mindless beast destined to spend untold amounts of time, possibly eternity, as an enforcer for the Time Wraiths probably wasn't what he had in mind.
* BodyHorror: As expected of what basically amounts to a rotting corpse stuck inside a Flash suit.
* TheBrute: He is the Speed Force's most powerful and terrifying enforcer.
* TheBusCameBack: He gets dragged off into the Speed Force by the Time Wraiths at the end of Season Two, but he later reappears as the Black Flash and starts hunting Eobard Thawne.
* ChestInsignia: It's much the same as Eobard Thawne's, though the black briefly turned white when he first became the Time Wraiths' servant.
* ClockRoaches: He serves the Speed Force, hunting time anomalies, with his primary target being Eobard Thawne.
* ComicBookMoviesDontUseCodenames: He is never directly referred to as the Black Flash. Eobard calls him "that thing", and Barry calls him by his old name, Hunter. Savitar breaks the trend in "Finish Line", presumably by virtue of his future knowledge.
* CompositeCharacter: In the comics, Zoom and the Black Flash are two distinctly different characters; here, Zoom ''becomes'' the Black Flash.
* CurbStompBattle: Eobard Thawne spends most of ''Legends'' Season Two running from this guy because he's afraid of being caught by him. Once the Black Flash manages to grab him, we see why, as he kills Thawne in about two seconds flat.
* DarkIsNotEvil: Despite his monstrous appearance and the [[Characters/ArrowverseHunterZolomon monstrous villain he once was]], the Black Flash is not evil, but merely an enforcer of the Speed Force's will without bias or cruelty.
* DeathOfPersonality: All traces of Hunter Zolomon's personality seem to have been lost following his transformation, leaving him as a mindless beast. Granted, he ''was'' a sociopathic, utterly vile monster who wanted to destroy TheMultiverse, and now he only tries to stop rogue speedsters, so this was probably for the best.
* {{Determinator}}: It doesn't matter where or when Thawne goes, the Black Flash ''will'' find him.
* DoNotTauntCthulhu: Thawne tries to turn him into a trophy by using the Spear of Destiny to lock him in a cell. Once freed, he wastes no time in hunting Thawne down and killing him with a single blow.
* TheDreaded: He's sent after the time aberrant Eobard Thawne, who is utterly scared shitless of him even after his partners figure out a way to hide from him. With how bad Eobard himself is, this is really saying something.
* DumbMuscle: He doesn't serve any function beyond finding and killing rogue speedsters. It's quite likely his once [[GeniusBruiser impressive mind]] has decayed along with his body.
* EarlyInstallmentWeirdness: When Hunter got transformed into the Black Flash, his insignia became red-and-white, as it is in the comics. However, this was jettisoned in favor of a red-and-black insignia, which is used from his second appearance onward.
* EvilMakesYouUgly: He was a {{Hunk}}y MrFanservice pre-KarmicTransformation.
* FacialHorror: Hunter's half-rotted face is given some lovely close-ups.
* FateWorseThanDeath: Creator/JohnWesleyShipp confirmed in an interview that Zoom is now trapped in the Speed Force, and will likely become a slave to it for eternity as the Black Flash. Ironically, his fate worse than death was to ''become'' [[TheGrimReaper Death]].
* FragileSpeedster: More so than the other speedsters. He's faster than the other speedsters, but much more susceptible to their weaknesses as seen with him getting easily killed by an ice blast from Killer Frost.
* GlassCannon: He's able to overpower and kill other speedsters with ease, but his durability leaves much to be desired. He's PunchedAcrossTheRoom by Thawne and easily frozen to pieces by Killer Frost, resulting in his death.
* GreaterScopeVillain: Of ''Legends'' Season Two, as the Black Flash's quest to erase Eobard Thawne from existence is what drives Thawne to create the Legion of Doom and hunt down the Spear of Destiny in order to rewrite reality and escape his foe's wrath.
* TheGrimReaper: In the Season Two finale, Zoom becomes the Arrowverse's version of the Black Flash.
* HandicappedBadass: He's blind, likely due to [[BodyHorror his eyes rotting away]]. It doesn't make him any less dangerous.
* HumanoidAbomination: The Black Flash is an undead speedster with decaying flesh.
* ImplacableMan:
** He is literally Death for speedsters; Eobard Thawne's attempts to outrun him are ultimately futile, and even hiding from him by not using the Speed Force is implied to be a temporary solution at best. Thawne believes that the only surefire way to permanently escape the Black Flash is to rewrite reality itself to undo his fate.
** When Barry returns to the Speed Force to save Wally, the Black Flash appears (presumably summoned by the Speed Force to ''force'' him to leave Wally) and is as nigh unstoppable as when he was Zoom.
* {{Irony}}: Zoom once boasted that he had "beat the rules" of the Speed Force. Now, he's the Speed Force's enforcer, targeting speedsters who broke its rules as he did.
* IWasQuiteALooker: He was a [[FaceOfAnAngelMindOfADemon very handsome man]] before the Time Wraiths got to him.
* KarmicTransformation: He's now as ugly and monstrous on the outside as he was on the inside as well.
* KickTheSonOfABitch: He spends his time as the Black Flash pursuing Eobard Thawne, a murderous supervillain.
* KnightOfCerebus: When this guy shows up, expect things to get a lot more serious.
* LaserGuidedKarma: Forced to atone for his crimes as Zoom, the Black Flash's main focus is to find Eobard Thawne, a man who should've died long ago for more reasons than one.
* LimitedWardrobe: He's still wearing the same outfit he was dragged off with in the Season 2 finale, broken mask and all.
* LivingMotionDetector: Due to being blind, he is unable to sense anything at all unless it's moving above a certain speed, at which point he can zero in on it.
* LogicalWeakness: He can sense any living thing by its movement. If a target remains still, he's caught flat-footed.
* LossOfIdentity: [[SameCharacterButDifferent All traces of Hunter Zolomon are long gone]], with the Black Flash being nothing but a servant of the Speed Force who operates purely on animal instinct.
* MeaningfulName: Before he became the Black Flash his name was HUNTER.
* MovieSuperheroesWearBlack: Justified, as he's literally the Arrowverse version of the [[MeaningfulName Black Flash]], the embodiment of Death for speedsters, meaning it would be strange if he ''didn't'' wear black. However, while he initially gained a red-and-white ChestInsignia as in the comics, it's become red-and-black when we see him fully in action, and his boots are black rather than red.
* OurZombiesAreDifferent: His transformation into the Black Flash reduced him to a zombie-like speedster with decaying flesh and operating on raw animal instinct. He has none of his humanity left, being only able to scream and growl. However, he's still a far cry from any traditional zombies, including Zombie Girder or the ones that the Legends faced in "Abominations". The Black Flash only hunts one individual in particular, and has no desire to devour him, only to end him.
* OutsideContextProblem:
** The Black Flash is something entirely new that Eobard Thawne has never encountered before.
** As mentioned above, he is summoned by the Speed Force to stop Barry from saving Wally.
* PayEvilUntoEvil: In the ''Legends'' Season Two finale, "Aruba", it erases Thawne from existence by performing Thawne's [[KarmicDeath favorite move of speed-stabbing]].
* PowerAtAPrice: As elaborated on in TookALevelInBadass below, transforming into the Black Flash turned the former Hunter Zolomon into an even more powerful and terrifying speedster, but at the cost of becoming little more than an animalistic beast for the Speed Force to send after its enemies.
* RedAndBlackAndEvilAllOver: Although he retains his black suit after becoming the Black Flash, it receives red highlights. He also leaves behind red lightning while he runs instead of blue from the Velocity drug. Ironically, he's ''less'' evil as the Black Flash than he ever was as Zoom; Zoom was a deranged sadist, the Black Flash is just the Speed Force's attack dog.
* SameCharacterButDifferent: He was once the evil Earth-2 speedster Hunter Zolomon/Zoom, but now, he's a zombie-like speedster who serves the Speed Force and hunts anomalies like Eobard Thawne, with all of his humanity ([[TheSociopath what little he had]]) gone so that he's reduced to raw animal instinct. When Barry encounters him in the Speed Force, he instantly recognized him, even [[SayMyName saying his old name in fear]].
* SerkisFolk: He's rendered entirely in CGI, probably to enhance the UncannyValley effect of his movements.
* TheSpeechless: As the Black Flash he doesn't speak, just screams and growls, suggesting that he's not even ''capable'' of speech anymore. Given his decayed physiology, it's entirely possible [[BodyHorror he doesn't even have vocal chords anymore]].
* SuperPersistentPredator: The Black Flash stalks Thawne no matter where on Earth or where in time he goes. He finally catches up to his quarry in the Season Two finale of ''Legends''.
* TookALevelInBadass: After becoming the Black Flash and taking on Time Wraith characteristics, he appears to have become even more powerful than before. Eobard is utterly terrified of him, and Barry just barely survives a confrontation with him, and only then because it's implied that the Speed Force may have allowed it.
* TouchOfDeath: Possibly in the ''Legends'' Season Two finale: After he fatally speed-stabs Eobard Thawne, instead of just dropping dead, Thawne, and the depowered Spear of Destiny that he was holding, start slowly disintegrating until they disappear entirely. This implies that whatever the Black Flash does when he has someone in his grasp, it's more than just killing them.
* TrueNeutral: The Black Flash doesn't take sides, he just goes after any Time Aberrations with no personal bias.
* UncertainDoom: Even though Black Flash was frozen and shattered by Killer Frost in Season Three, the chance that he could be reconstructed by the Speed Force was still there. With the Speed Force gone, however, Hunter Zolomon might finally be well and truly dead.
* WasOnceAMan: Zoom's humanity was already highly questionable, but as the Black Flash, he is without a doubt no longer human.
* WolverineClaws: Played with. He still has claws on his gloves, but he prefers to just force his whole hand through his victims.
* WorfHadTheFlu: Even with his incredible speed and power, he's as vulnerable to cold as any other speedster, and in fact seems to be ''more'' vulnerable to it than he was as Zoom.[[labelnote:Explanation]]As Zoom, he was resistant enough that Killer Frost of Earth-2 had to keep freezing him continuously in order to just slow him down, whereas a burst of cold from Killer Frost of Earth-1 not only slows him, but actually kills him.[[/labelnote]] Killer Frost proves this in the Season Three finale of ''The Flash'' seemingly killing him with a concentrated burst.

!!! '''Appearances:''' ''Series/{{The Flash|2014}}''

-->''"It's a little bit...negative."''
-->--'''Eobard Thawne'''

A creation of Eobard Thawne's, his own personal Speed Force. Providing all the same abilities as the old one, it requires negative emotions to use.

* AmbiguousDisorder: Users of the Negative Speed Force generally have black-and-white thinking, poor impulse control, a failure to understand other people, and a tendency to use violence as a first resort
* AmbiguousSituation:
** Black Flash has the same red lightning as a user of the Negative Speed Force, but there's no other indication he has a connection to it.
** Even though it's been established to leech power from the Speed Force, nothing is said of how the Speed Force's destruction will impact it and those using its power.
* DangerousForbiddenTechnique: Thawne, of all people, is reluctant to share its secrets with XS because of the sheer danger it presents to one's mind.
* TheDarkSide: It's a Speed Force fueled by ThePowerOfHate, and using it does not do wonders for a speedster's mental state.
* DemonicHeadShake: Speedsters connected to the Negative Speed Force can vibrate their face to disguise themselves, but this is done menacingly with their red glowing eyes.
* EvilKnockoff: A Speed Force created by Eobard Thawne but powered by negative emotions.
* OlderHeroVsYoungerVillain: A variation. The first Speed Force is an omnipresent part of history, having been around since before and after the existence of the universe. The Negative Speed Force, relatively speaking, is a newer creation of Thawne's.
* PlaceBeyondTime: Similar to the positive Speed Force, it exists beyond time, but it also shelters its users from changes to the timeline.
* PowerParasite: The Negative Speed Force leeches positive energy like tachyons from the regular Speed Force and converts it to negative energy for power.
* RedIsViolent: The timestreams of the Negative Speed Force are bright red, and any speedster connected to it gets red lightning and glowing red eyes.
* VoiceOfTheLegion: Negative Speedsters can disguise their voices with vibration but theirs is usually more distorted and demonic sounding.

!!! '''Species''': Angel
!!! '''Played By:''' Creator/HaroldPerrineau

An angel sent to watch over John to warn him of the dark forces that are starting to rise on Earth.

* AllPowerfulBystander: Manny probably could destroy most MonsterOfTheWeek threats John faces with a swipe of his hand, but he doesn't because angels cannot interfere directly with the mortal realm.
* BewareTheNiceOnes: He is able to annihilate a Fallen Angel within seconds.
* BigBad: Of ''Constantine'', though John never finds out about it (on-screen). The Brujería work for him, which means he is behind the Rising Darkness.
* CelebrityParadox:
** ''Series/{{LOST}}'' was mentioned on the very first episode of ''Series/{{Arrow}}''. His actor is a main cast member there for most of its run.
** ''Franchise/TheMatrix'' is acknowledged to exist in this universe. His actor was in the [[Film/TheMatrixReloaded last]] [[Film/TheMatrixRevolutions two]] films of the film trilogy.
* CrypticConversation: Mocked by John, but he explains this is actually how he ''has'' to talk due the Angel's code of non-interference.
* DeadpanSnarker: Stands toe-to-toe with John in SnarkToSnarkCombat.
* DemonicPossession: Well, Angelic Possession actually, but basically the same thing. Manny has a habit of talking to John by possessing people nearby to him.
* DontFearTheReaper: He often shows up when people are about to die.
* EvilAllAlong: The Brujería ''work for him''.
* HolierThanThou: 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.
* HumansAreFlawed: 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.
* MoralityChain: 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.
* OnlyKnownByHisNickname: Manny is not his true name, since knowing it would give John a measure of power over him.
* ScrewTheRulesImDoingWhatsRight: Despite his orders of non-interference Manny intervenes to save Zed from a murderous fallen Angel.
* SpiritAdvisor: Of sorts to John, though Constantine complains he's actually ''very'' unhelpful.
* StealthHiBye: It's a RunningGag for him to vanish mid-conversation, much to John's annoyance.
* SupernaturalGoldEyes: Par the course for angels in this show, he has golden eyes.
* TheManBehindTheMan: The Angel pulling the strings of the Brujería.
* TimeStandsStill: Can pause everything but himself and someone else when he wants to have a private conversation.
* WhatHappenedToTheMouse: Well it's obvious that Constantine put a stop to his EvilPlan sometime between the end of ''Constantine'' and John's joining ''Legends of Tomorrow'', but the specifics are never elaborated upon.

* SadisticChoice: They force Constantine to choose between saving either Astra's or Ray Palmer's soul.
* StupidEvil: They know that Neron is seeking to overthrow them, but [[spoiler: they can't resist the chance of torturing Constantine even though he's their best bet at stopping him.]]

Every time the First takes a soul, he's exacting revenge, paying back the Almighty for casting him out."''
->-- '''John Constantine'''

The first angel to fall from God's Grace.

* AlternateSelf: Since ''Series/{{Lucifer|2016}}'' is canon in the multiverse, he is technically the Earth-1 counterpart of [[ComicBook/{{Lucifer}} Lucifer Morningstar]], both being Satan.[[note]]It's complicated. ''Hellblazer'' and ''Lucifer'' comics share the same continuity, but since the two started out separate, their depictions of Satan are treated as different characters. In the comics, the First of the Fallen was the first ruler of Hell. He was deposed by Lucifer Morningstar, but later regained the title after the latter decided to leave Hell. The name Satan is more associated with the First than with Lucifer.[[/note]]
* ArchEnemy: 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.
* DealWithTheDevil: It's established in ''Constantine'' that he offers service to humans in exchange for their souls.
* GreaterScopeVillain: Of ''Series/{{Constantine}}'', especially the episodes "The Devil's Vinyl", where a vinyl with his voice recorded on it [[PsychicAssistedSuicide drives people to kill themselves]], and "Waiting for the Man", where one of his followers sacrifices little girls to him.

!!! '''Appearances:''' ''Series/{{Constantine}}'' | ''Series/LegendsOfTomorrow'' [[note]] Flashback of his scene in ''Constantine'' [[/note]]

->''"You can't save her."''

The demon who took Astra Logue to Hell as a result of John Constantine's arrogant actions.

* AbortedArc: 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".
* ArchEnemy: To Constantine. Even after he took Astra, Nergal has sent his minions for others John cares just to twist the knife against him further.
* ForTheEvulz: He's a demon; it's what he does.
* GreaterScopeVillain:
** 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.
* MesopotamianMonstrosity: Nergal’s name is that of a god from Myth/MesopotamianMythology. In the original comics, the connection was made more explicit.
* SmallRoleBigImpact:
** 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.

* TheDragon: To Nergal, in the pilot.
* AGodAmI: "[[BlasphemousBoast Down here, I'M GOD!]]" He says it as he notices he's absolutely surrounded by electricity.
* FluffyTheTerrible: The name "Furcifer" sounds like a good name for a demon, until you learn that it's actually a type of [[UglyCute Chameleon]].
* AFormYouAreComfortableWith: When he is summoned by John, he takes on [[EvilDoppelganger John's form]], complete with BlackEyesOfEvil. In the original pilot, however; Furcifer didn't take John's appearance but a random security guard. His true form is something else entirely.
* PowerOfTheStorm: Able to summon powerful lightning and tempests.
* ShockAndAwe: Has control over electricity which manifests in control over power lines, a city's electrical grid and even dead bodies.

!!! '''Appearances:''' ''Series/LegendsOfTomorrow''

A demon who is after Constantine's soul and the Legends' main adversary in Season Four.

* AdaptationalUgliness: Comics Neron had a humanoid appearance and quite an attractive one at that. This Neron has a NightmareFace whenever he possesses a host and a LivingShadow when in his true form.
* AdaptationalWimp: Comics Neron is stated to be the most powerful magical being in the DC universe, being a NighInvulnerable RealityWarper. 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.
* ArchEnemy: 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.
* BigBad: Of ''Legends'' Season 4.
* BigBadDuumvirate: With his lover Tabitha, after she is freed nearing the end of ''Legends'' Season 4.
* DemonicPossession: Possesses Ray after Nora and John pull him out of Desmond.
* TheDreaded: 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.
* EvenEvilHasLovedOnes: As evil as they both may be, Neron genuinely loves Tabitha.
* EvilIsPetty: 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.
* FauxAffablyEvil: 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.
* HatePlague: 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.
* IGaveMyWord: 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.
* KilledOffForReal: 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.
* TheManBehindTheMan: He's Hank's superior in the half-baked scheme to use magical creatures as living weapons.
* TheMindIsAPlayThingOfTheBody: In-series. He takes on a few personality traits of whoever he is possessing. While inside Desmond's body, he is an AffablyEvil 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.
* NightmareFace: Lets just say his face is not something people with Trypophobia should look at.
* PungeonMaster: 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.
* {{Sadist}}: According to John, he doesn't just want to win, he wants to win the cruelest way possible.
* TheStarscream: He wants to overthrow the ruling triumvirate of Hell.
* SupernaturalFearInducer: In addition to his HatePlague 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.
* VileVillainSaccharineShow: The excessively silly Season Four gets balanced out by the fittingly despicable and nightmarish Neron.
* YouHaveOutlivedYourUsefulness: Murders Hank Heywood after the latter tries to stand up to him.

A mysterious trickster from the Fifth Dimension.

* AchillesHeel: 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]]For 90 days, if this Mxy follows the comic book rules.[[/note]]
* AdaptationalAttractiveness: 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.
* AdaptationalBadass: Most versions of the character are 90-pound weaklings and are helpless without their powers. Not this one.
* AdaptationalCurves: Instead of being 3 inches short and scrawny, he's tall and fit in his first body.
* AdaptationalDyeJob: He has white hair in the comics due to his age, while both of his forms are brunettes here.
* AdaptationalPersonalityChange: In the comics, Mxy is a trickster imp whose primary motivation is trolling Superman. Here he's a StalkerWithACrush fixated on Supergirl, though he later comes around.
* AgeLift: Usually depicted as a balding old man. Here, he's around the late 20s to early 30s[[note]]His actor was 31 when he started playing him[[/note]]. His later appearance splits the difference and shifts him more into a middle aged man.
* AlliterativeName: '''M'''r. '''M'''xyzptlk.
* ArsonMurderAndJaywalking: 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.
* TheAtoner: In Season 5, he has been ordered to atone for his mischief by helping all of the people he antagonized in the past.
* BadassFingersnap: He sometimes uses fingersnaps to initiate his reality distortion.
* BewareTheSillyOnes: 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''.
* BroughtDownToBadass: 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.
* BroughtToYouByTheLetterS: Parodied: he dons a Superman outfit emblazoned with the letter "M" in a pentagonal shield. Kara's not amused.
* CloudCuckoolander: To be fair, it's probably hard to be of sound mind when you can bend the laws of the Universe into a pretzel.
* CompositeCharacter: 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.
* AGodAmI: He boasts to Mon-El, "I'm a god, and you're a loser."
* GoodFeelsGood: After helping Kara, he contemplates that being a better person genuinely feels good to him.
* HeelFaceTurn: In his second appearance, he has stopped antagonizing people and instead tries to help Kara fixing her relationship with Lena.
* IJustWantToBeLoved: 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.
* ILied: 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.
* MomentKiller: Interrupts a romantic moment between Kara and Mon-El at the end of "Luthors".
* NoOntologicalInertia: All of the damage he causes, such as the destroyed statue of Jor-El, resets when he's banished back to the 5th dimension.
* NoPronunciationGuide: His name has no vowels in it unless you count "y". Good luck pronouncing it.[[note]]His appearance on ''WesternAnimation/SupermanTheAnimatedSeries'' ''did'' thankfully provide a useful guide: "mix-yes-spit-lick." It's hardly the only pronunciation, though, as "Mix-iz-pit-ulk" was an earlier one.[[/note]] Kara pronounces it "Mix-yiz-pitulik".
* NotWearingTights: Mxy is usually wearing colorful tights in the comics. [[Series/LoisAndClark Like]] [[Series/{{Smallville}} all]] LiveActionAdaptation of the character, he's wearing black clothes. The closest thing he wears to a spandex is the fake Superman suit.
* TheNthDoctor: It's revealed in "It's a Super Life" that he can glamour his appearance, which accounts for being played by different actors.
* PhysicalGod: He thinks of himself as a god. Given he can [[RealityWarper warp reality]] on a whim, he has a right to this claim.
* RealityWarper: 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.
* RoguesGalleryTransplant: Mr. Mxy usually spends his days annoying Kara's cousin Clark.
* SmugSuper: Thanks to his vast powers, he mocks Mon-El at every turn as an inferior suitor for Kara.
* StalkerWithACrush: 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.
* UnexpectedCharacter: 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, [[GreatGazoo 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.

* DraggedOffToHell: [[spoiler: 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.]]
* EvilAllAlong: She turns out to have been manipulating Kara in order to get home herself.
* FauxAffablyEvil: Once she drops the mask.
* FinalBoss: She is Supergirl's very last opponent along with Lex for the entire series.
* LaughablyEvil: 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 [[LargeHam her over-the-top behaviour]] and {{Camp}} personality.
* ALighterShadeOfBlack: Between her and [[spoiler: 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]].
* NotQuiteDead: 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.
* PowerLimiter: 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.
* RaceLift: She goes from white to Eurasian in this adaptation, and this is due to the series' SettingUpdate of UsefulNotes/TheNewTens.
* StupidEvil: 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.
* UnholyMatrimony: [[spoiler: 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.]]

An extraterrestrial being of infinite power.

* AdaptationalSpeciesChange: He is a Maltusian since he is a CompositeCharacter with Krona.
* AdaptationalVillainy: He is much more aggressive than his comics counterpart in his plan to save TheMultiverse by destroying universes that fail his test, and he shows dismissive cruelty toward anyone who calls him out on it.
* AesopEnforcer: He ensures that [[spoiler:Oliver learns that there are some times he can't change things and J'onn learns to let go of his past.]]
* AlternateSelf: 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 [[AllForNothing 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.
* AmbiguouslyEvil: His manipulative and secretive nature cast doubts on whether he wants to cause the Crisis or if he is trying to avert it. [[spoiler:He's eventually confirmed to be on the level, but he's a solid WellIntentionedExtremist.]]
* AmbitionIsEvil: 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.
* BackFromTheDead: [[spoiler: 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.]]
* BadassBaritone: He has a very deep voice.
* BadassCape: A PhysicalGod capable of wiping out existence who wears a black-and-yellow cape.
* BatmanGambit:
** His gambit to bring Malefic from the Phantom Zone was a plan to [[spoiler: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.
* BeenThereShapedHistory:
** 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 WasOnceAMan, a scientist who tried to peer into the dawn of time and inevitably opened up TheMultiverse to the Antimatter Universe and allowed Mobius the Antimonitor to discover its existence and attempt to destroy it.
* BigBad: He is the one responsible for the events of ''Series/{{Elseworlds|2018}}'', though Dr. John Deegan is the one actually using the Book of Destiny to warp reality.
* BigGood: He's become this for the whole TheMultiverse with the Crisis approaching, being the one chance everyone has to continue existing. However he's still a WellIntentionedExtremist. [[spoiler: After he dies in Hour 3 of the Crisis, Oliver as the Spectre takes over his role for the last 2 parts.]]
* TheChessmaster: The Monitor spends Season 8 of ''Arrow'', Season 6 of ''The Flash'', and Season 5 of ''Supergirl'' manipulating events and collecting various allies, [[Series/CrisisOnInfiniteEarths2019 all to oppose the Anti-Monitor]].
* BlackAndGrayMorality: 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.
* CompositeCharacter:
** With the Monitors as a whole, who are less benevolent than the particular Monitor he is based off in the comics.
** Since the [[ComicBook/GreenLantern Green Lantern Corps]] were AdaptedOut of this adaptation, his homeworld is Maltus, and Mar Novu takes the role of [[spoiler: Krona as the one who attempted to peer into the dawn of time to watch creation unfold.]]
* CosmicEntity: He's about a textbook example as you can get and literally referred to one InUniverse.
* CreateYourOwnVillain: 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.
* DealWithTheDevil:
** 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. [[spoiler: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, [[spoiler: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.]]
* EvilIsNotAToy: He revives Lex Luthor to help in the Crisis. Unsurprisingly, things go poorly.
* ExBigBad: While [[GoodAllAlong he was never evil]], he did serve as the main threat of ''Series/{{Elseworlds|2018}}'', before he went on to become the BigGood for the Arrowverse leading up to ''Series/{{Crisis on Infinite Earths|2019}}''.
* ForScience: 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.
* ForTheLulz: [[spoiler: 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.]]
* AGodAmI: {{Downplayed|Trope}}. 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.
* GoodAllAlong: 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 [[PetTheDog kinder]] than he seems, although he remains a WellIntentionedExtremist and an example of GoodIsNotNice.
* GoodIsNotNice: 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.
* GreaterScopeVillain:
** 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 [[spoiler: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. [[spoiler: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 GreaterScopeVillain of the entire show.
* HappilyMarried: [[spoiler:It's revealed he was married to a scientist partner and lived happily with her.]]
* TheHeavy: 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 AmbiguouslyEvil god.
* HeroKiller: 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 ''Series/TheFlash1990'' except for the titular protagonist.
* HiddenDepths: Hour Three of ''Crisis On Infinite Earths'' reveals that Novu once had a family, and that he regrets placing his work above them.
* IronicName: In his origin story it turns out "the Monitor" was originally the affectionate nickname he gave his wife, who acted as his MissionControl 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.
* JerkassGods: 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 [[WellIntentionedExtremist noble goals]], is quite a harsh and callous individual.
* MagicalNegro: A god-like entity with an appearance of an African human male.
* MyGreatestFailure: He considers allowing the Anti-Monitor to come into existence to be this.
* NamedByTheAdaptation: 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 [[RetCanon based on the Arrowverse version]].
* NeverMyFault: 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.
* NiceJobBreakingItHero: 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 [[spoiler: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 [[spoiler:open the Anti-Monitor's prison and thus endanger the Multiverse as a whole]].
** [[spoiler:Him travelling to the dawn of time was what unleashed the Anti-Monitor in the first place.]]
* NotHelpingYourCase: While his fears are rightful, his morally ambiguous approach makes him very distrusted by everyone.
* NotSoAboveItAll: 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.
* NotSoStoic:
** Meeting with Oliver at the end of ''Arrow'' Season Seven, the Monitor sounds genuinely regretful about [[spoiler:Oliver's imminent, inevitable death]].
** [[spoiler: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.
* OmniscientMoralityLicense: Certainly believes he has one, since he's trying to save TheMultiverse.
* PetTheDog:
** [[spoiler:Grants Felicity's request to be reunited with Oliver with no strings attached.]]
** When speaking to Barry about the latter's [[spoiler: upcoming death]], Novu seems as regretful as he ever gets, showing definite VillainRespect for Barry.
** In Season 8 of ''Arrow'', despite the [[AmbiguouslyEvil questions raised]] about Novu's morality, he does this a few times:
*** He is revealed to have [[spoiler: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 [[spoiler:passes a SecretTestOfCharacter 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.
* PhysicalGod: He's capable of wiping out universes and is tremendously powerful.
* PromotedToOpeningTitles: [=LaMonica=] Garrett gets upgraded to series regular for ''The Flash'' and ''Arrow'', simultaneously.
* RealityWarper: He is capable of erasing universes.
* RealityWritingBook: 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.
* RetCanon: While the Monitor has always existed, the name Mar Novu is [[NamedByTheAdaptation a creation of the show]], which too eventually made its way into the comics.
* SarcasmFailure: Even the seemingly all-powerful and ever-collected Monitor is left speechless when he hears Lex Luthor unironically call himself a hero.
* SecretTestOfCharacter:
** [[spoiler: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.]]
** [[spoiler: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.]]
* ScaryBlackMan: A PhysicalGod capable of wiping existence who has an appearance of an African human.
* SinkOrSwimMentor: 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.
* SmallRoleBigImpact: 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 GreaterScopeVillain above.
* TheStoic: Unemotional, patient, and composed at all times, Novu is the picture of godly detachment.
* SuperReflexes: When Earth-90 Barry charges him, Novu casually flicks a finger and conjures a portal before Barry can do anything.
* SuperheroParadox: 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.
* ThinkingUpPortals: With a twitch of his finger, he can conjure portals from anywhere to anywhere, so quickly that he can portal away a speedster effortlessly.
* UnscrupulousHero: He is willing to do morally dubious things to save the multiverse, like destroying universes or endangering alternate versions of Superman.
* WasOnceAMan: 10,000 years ago, he was once a mortal time traveler who journeyed to the dawn of time.
* WellIntentionedExtremist: 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''.
* WowingCthulhu:
** While he [[TheStoic 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. [[spoiler:He tells Oliver with sincerity that he is sorry to inform him of his death in the Crisis, and the first time he [[NotSoStoic actually seems to show emotion]] is when he is explaining Oliver’s apparent HeroicSacrifice to the other heroes at the end of [[Recap/Supergirl2015S5E9CrisisOnInfiniteEarthsPartOne 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.
* YouHaveFailedMe: When Earth-90 Barry Allen asks him why he's causing destruction, he simply responds with this trope.

An AlternateUniverse version of The Monitor from the Antimatter Universe.

* AdaptationalAttractiveness: 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.
* AdvancingWallOfDoom: He destroys universes with a wave of antimatter that consumes everything it touches.
* AlternateSelf: To the Monitor, being his antimatter counterpart.
* AndIMustScream: [[spoiler: His final fate is being shrinked down and trapped in the Microverse.]]
* ArchEnemy: 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.
* AnthropomorphicPersonification: 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.
* AtrociousAlias: 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.)
* AttackOfThe50FootWhatever: 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. [[spoiler: He grows gigantic in the final confrontation with the heroes.]]
* BadassBoast:
** His first on-screen speaking lines are him delivering one to [[spoiler:Harbinger]].
--->'''Anti-Monitor''': [[MultiversalConqueror 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 boasting
--->'''Anti-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.
* TheBadGuyWins: He actually did succeed in his EvilPlan 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.
* BaldOfEvil: Unlike the beard and strips of hair on the Monitor, the Anti-Monitor is totally bare-headed.
* BarrierWarrior: When he gets simultaneously attacked by all the Earth-Prime heroes, he activates a force field that completely negates all their attacks.
* BigBad: 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 BigBadEnsemble for every season in Year Eight of the Arrowverse.
* BroughtDownToBadass: [[spoiler: 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.]]
* CompositeCharacter: 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 ComicBook/BlackestNight, who was the primal abyss given form and who sought to destroy all living things with his Black Lanterns.
* ContrastingSequelAntagonist: 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.
* CosmicEntity: He has the same powers as Mar Novu, and is stated by the latter to be far more powerful.
* CreepyBlueEyes: He has very pale, watery blue eyes that bring to mind supernatural creatures in folklore.
* DarkIsEvil: 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.
* DemonicPossession: [[spoiler: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.]]
* TheDreaded: Everyone who fears the [[VaguenessIsComing Crisis]] fears him, they just don't know it yet. Hell, even the Monitor is scared of him!
* EarlyBirdCameo: 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.
* EvilDoppelganger: The evil antimatter counterpart to our Monitor.
* EvilGloating: 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.
* EvilIsHammy: He could rival [[Franchise/MarvelCinematicUniverse Thanos]] in this regard, with how much he loves to make dramatic {{Badass Boast}}s.
* EvilSoundsDeep: 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 ComicBook/{{Apocalypse}}.
* FacialHorror: His face is hideously deformed, making him look like a twisted, undead copy of the Monitor.
* FinalBoss: [[spoiler:Of ''Arrow''. He is the last opponent Oliver Queen faces and ultimately has to sacrifice himself to stop.]]
* AGodAmI: 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 [[PhysicalGod has the power to back it up]].
* GravityMaster: While [[spoiler:possessing Harbinger]], the Anti-Monitor demonstrates the ability to increase gravity to the point that even Kryptonians can't move.
* GreaterScopeVillain: ''Of the entire Series/{{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.
* HeroKiller: The Anti-Monitor's multiversal rampage has destroyed countless worlds and slain countless heroes, but he truly earns this status by [[spoiler: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.]]
* HiddenVillain:
** 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 InUniverse example, as promotional material has revealed him long before the pre-Crisis storylines, and anyone familiar with the [[ComicBook/CrisisOnInfiniteEarths 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.
* InTheirOwnImage: In destroying the multiverse, the Anti-Monitor intends to replace it with the Antimatter Universe so that he can rule over it.
* JerkassGods: While the Monitor is no paragon of virtue himself, the Anti-Monitor is infinitely worse, being a cruel, sadistic, and megalomaniacal OmnicidalManiac who destroys universes so that he can rule over the Antimatter Universe as its sole deity.
* TheJuggernaut:
** The antimatter wave he uses cannot be stopped, only delayed. [[spoiler: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 [[spoiler:using Harbinger as a vessel rather than fighting himself]], he proves capable of [[spoiler:overpowering Superman of Earth-96 with ease, defeating the assembled heroes without breaking a sweat, and overwhelming the Monitor himself after a brief contest]].
* KickTheDog:
** [[spoiler: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.]]
** [[spoiler:He uses Earth-90's Barry Allen as a power source for the antimatter cannon.]]
* KnightOfCerebus: 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.
* LightIsNotGood: The antimatter wave consumes Earths in a bright light and leaves a white void behind. [[spoiler:Harbinger's eyes also glow white while the Anti-Monitor possesses her.]]
* ManipulativeBastard: He exploited Nash Wells' hatred for the Monitor in order to free himself.
* MeaningfulName: A [[https://en.wikipedia.org/wiki/M%C3%B6bius_strip 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.
* MultiversalConqueror: He has invaded and destroyed countless universes.
* NighInvulnerable: 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.
* OffscreenVillainy: We don't see him [[spoiler: destroy Earth-2]] but we know he’s the cause.
* OmnicidalManiac: His goal appears to be the destruction of the entire Multiverse, one universe at a time.
* TheOmniscient: 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.
* PaletteSwap:
** 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.
* PhysicalGod: He's even more powerful than the Monitor, being able to unleash a wave of antimatter capable of destroying the entire multiverse. [[spoiler: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.]]
* PowerParasite: As he destroys more and more worlds, the Anti-Monitor saps power from the Monitor. [[spoiler: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.]]
* RedShirtArmy: 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.
* RetGone: 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}}: [[spoiler: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.]]
* SealedEvilInACan: [[spoiler:He was originally sealed in a monolith, until [[NiceJobBreakingItHero Nash Wells destroyed it and freed him]].]]
* SlidingScaleOfVillainThreat: 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.
* SparedByTheAdaptation: From a certain point of view at least. [[spoiler: The original event had him flat out killed in a RasputinianDeath 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 AndIMustScream situation.]]
* SuperheroMovieVillainsDie: [[AvertedTrope Averted]]. He might be the only character to be have CompleteImmortality, 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.
* YouCantFightFate: As he proudly boasts, he is "destiny incarnate" and the one villain who is completely immune to being RetGone. Even when the Paragons prevent one Mar Novu from creating his existence, another Mar Novu succumbs to ambition and inadvertently creates him instead.
* VoiceOfTheLegion: He has a heavily distorted reverberating voice, to an even greater extent than Mar Novu.
* WorfHadTheFlu: [[spoiler: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 NoSell 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.]]

!!Spectres
[[folder:In General]]
[[ComicBook/TheSpectre Spectres]] are mysteriously spirit-like beings who are in-tune with TheMultiverse tasked with watching over it.
-----
* AdaptationalDistillation: 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 TheMultiverse with RealityWarper powers.
* AdaptationalModesty: 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 WalkingShirtlessScene.
* AdaptationalWimp: 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 life[[note]] although it should be noted that the Comics Spectre received a power boost from various magical heroes during his fight whereas Oliver is fighting completely on his own[[/note]] and the Anti-Monitor was ultimately not defeated (though he was severely weakened).
* ColorMotif: Green seems to be the color they are always associated with. It's the color of the GhostlyGlow they display and the color of Oliver's Spectre outfit.
* DecompositeCharacter: 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 [[TheMentor mentor]].
* GuardianOfTheMultiverse: Along with the Monitor, this seems to be their main role. To server as TheWatcher and only step in when all else fails.
* InTheHood: 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.
* OurGhostsAreDifferent: 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.
* OutsideContextProblem: 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.
* PhysicalGod: They are the closest thing we get, save for actual gods, being {{Reality Warper}}s who can match up to a multiverse destroying CosmicEntity.
* PowerEchoes: As the Spectre, Oliver's voice gains a reverb effect.
* RealityWarping: 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, unlocking a speedster's powers to give them full access to the Speed Force, fighting on even ground against another CosmicEntity, and the most impressive one being recreating a destroyed Multiverse (albeit with some assistance) after it got obliterated with antimatter.
* SummonBiggerFish: Even the Monitor could not defeat the Anti-Monitor, so Oliver as the Spectre is brought in to finish the job.

!!The Fates
[[folder:In General]]
A trio of sister goddesses who are eons old and used the Loom of Fate to decide the destiny of the multiverse. Until one of them, Clotho, scattered the Loom of Fate across the multiverse before being locked away in a magical prison. She is eventually freed by the Legends in Season 4 and assumes the name of "Charlie" and the appearance of a departed Legend, Amaya Jiwe, at first seeming to merely be a magical shapeshifter. In Season 5, thanks to the Crisis resulting in a MergedReality, Charlie informs the Legends that the pieces of the Loom are all now on Earth-Prime and her sisters are coming for her.

* AscendedExtra: 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).
* BigBad: Atropos and Lachesis form a BigBadDuumvirate for ''Legends of Tomorrow'' season 5. Clotho, the third Fate, is the WhiteSheep, and actually the Legend known as Charlie.
* BigSisterBully: 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 ParentalSubstitute to Astra, whom she chose to be Clotho's [[ReplacementGoldfish replacement]].
* BrownNoteBeing: True to Greek Mythology they have true forms that kill all mortals in their presence.
* ContrastingSequelAntagonist: The first ''Series/{{Arrowverse}}'' [[BigBad big bads]] to be actual deities from real-life mythology (specifically, Myth/ClassicalMythology). [[note]]Savitar tried to claim he was the actual Hindu deity that served as his namesake, but it [[GodGuise was all a ruse]].[[/note]]
* TheEvilsOfFreeWill: 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.
* TimeAbyss: They are probably as old as the multiverse itself.
* VoluntaryShapeshifting: All of them are capable of shapeshifting, although for most of Season 4, Clotho is [[ShapeshifterModeLock locked]] to Amaya's likeness.
* TheWeirdSisters: The Moirai themselves, the three sisters who decided the fates of mankind.
* WellIntentionedExtremist: They genuinely believe humanity is better off without free will.

!!! '''First Appearance:''' "[[Recap/LegendsOfTomorrowS5E4AHeadOfHerTime A Head of Her Time]]" (''Legends of Tomorrow'' 5x4)
!!! '''Appearances:''' ''Series/LegendsOfTomorrow''
The 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.

* BigBadDuumvirate: For season 5, along with her sister Atropos, though she is clearly the one in charge.
* BrainsAndBrawn: The brains to Atropos's brawn. While Atropos gets her hands dirty, Lachesis's specialty is scheming and manipulation.
* TheCorrupter: She's the one who has been pulling the strings on Astra, stoking the girl's hatred of John Constantine.
* EvilMentor: 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.
* FallenOnHardTimesJob: For a former Goddess of Fate, making soul coins in Hell is clearly this.
* FateWorseThanDeath: 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.
* GodWasMyCopilot: 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".
* HumanityEnsues: After the Loom is destroyed, she and Charlie both turn into mortals.
* KarmaHoudini: 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.
* TheLeader: As the oldest, Charlie refers to Lachesis as the leader of the Fates.
* TheManBehindTheMan: She's the one manipulating Astra, the initial apparent BigBad for Season 5.
* ParentalSubstitute: To Astra, whom she took under her wing in Hell and was planning to use to [[ReplacementGoldfish replace]] Clotho as the third Fate.
* PhysicalGod: As one of the three [[Myth/ClassicalMythology Moirai]].

!!! '''Appearances:''' ''Series/LegendsOfTomorrow''
The 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.
----
* AnArmAndALeg: 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.
* BadWithTheBone: Her weapons of choice are daggers made of bone she pulls from her forearm.
* BigBadDuumvirate: For season 5, along with her sister Lachesis, though she acts more like TheDragon.
* BrainsAndBrawn: The brawn to Lachesis's brains. She is ''very'' good at getting her hands dirty and killing people, while Lachesis tends to handle the [[ManipulativeBastard manipulation]].
* TheGrimReaper: The Greek Mythological equivalent. Being the Fate in charge of cutting the thread to end a person’s life.
* HeroKiller: In her first appearance she kills Charlie's band-mates and by the end of the episode [[spoiler: she kills Behrad]], while the heroes don't stand a chance against her. Oh, but it gets worse. In her next major appearance, she [[{{Necromancer}} summons]] a ZombieApocalypse upon London that [[spoiler: ultimately kills Sara, Ava, Nate, Zari, Mick, and Constantine]] while she herself [[spoiler: kills both Astra and Gary with her bone knives]].
* TheJuggernaut: Given that she's a PhysicalGod, little to nothing can harm her, while she in turns brings mass death and destruction in her wake.
* KarmicDeath: She dies by being dragged into the Loom, the very artifact her and her sister committed several atrocities for to find, seconds before it's destroyed in an explosion.
* KnightOfCerebus: 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 [[TheJuggernaut unstoppable]] force of nature that ''will'' get the Loom of Fate by any means. In the episode's climax [[spoiler: she even kills Behrad]].
* MurderIsTheBestSolution: If there is any perceived problem, her first reaction is to brutally kill it.
* {{Necromancer}}:
** She resurrects the dead crew of ''Series/{{Supernatural}}'' to attack the Legends.
** Taken UpToEleven when she unleashes a ZombieApocalypse on England to get rid of the Legends.
* NoSell: 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.
* NoSocialSkills: 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.
* PhysicalGod: As one of the three [[Myth/ClassicalMythology Moirai]].
* SuperpowerLottery: SuperStrength, NighInvulnerability, TimeTravel, [[ToHellAndBack the ability to easily go to and from Hell]], [[{{Necromancer}} necromancy]], [[VoluntaryShapeshifter 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 [[YouCannotGraspTheTrueForm 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.
* YouCannotGraspTheTrueForm: 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.
* YouCantFightFate: 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.

A wraith-like species originating from a dark planet at the edge of the Rao system, they are now native to the Phantom Zone, after being banished there.
----
* BadGuysDoTheDirtyWork: They are the ones who [[spoiler: [[DraggedOffToHell drag]] Nyxlygsptlnz and Lex into the Phantom Zone in the SeriesFinale]].
* {{Expy}}: Evil, soul-sucking creatures that cause [[GhostlyChill coldness]] and act as prison guards? The Phantoms obviously take more than a few cues from the [[Literature/HarryPotter Dementors]].
* {{Flight}}: [[ExactlyWhatItSaysOnTheTin They can fly.]]
* GhostlyChill: They cause nearby objects to freeze from their mere presence.
* HealingFactor: Physical injuries are of minor concern to them, as they heal almost instantly.
* NoOntologicalInertia: Destroying the Phantom chrysalis returns all the lost souls to their owners and undoes their Phantom transformations.
* TheSoulless: Since they turn people into Phantoms by stealing their souls, obviously they don't have them.
* SupernaturalFearInducer: The Phantoms can force others to experience their worst fears, and in the [[EldritchLocation Phantom Zone]], they have an eternity to drive the prisoners mad.
* ViralTransformation: Anyone scratched by the Phantoms eventually loses their life force, which migrates to the Phantoms' nest, and becomes a new Phantom. With each new Phantom, conversions happen progressively faster. They were sealed in the Phantom Zone because they were a plague upon the galaxy.
* YourSoulIsMine: They steal the souls of those they infect, which causes them to mutate into a new Phantom.

!!! '''Appearances:''' ''Series/{{Supergirl|2015}}'' | ''Series/{{The Flash|2014}}''

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.
----
* AdaptationalAbomination: The ''WesternAnimation/BatmanTheBraveAndTheBold'' version was a human who happened to have his trademark TheMusicMeister power. This version of the Music Meister is an EldritchAbomination with seemingly limitless RealityWarper powers.
* AdaptationalBadass: The ''WesternAnimation/BatmanTheBraveAndTheBold'' Music Meister could [[BrainwashedAndCrazy 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 RealityWarper with a [[SuperPowerLottery wide array of impressive powers]], including [[PowerParasite draining the powers of his victims]].
* AdaptationalDyeJob: In ''WesternAnimation/BatmanTheBraveAndTheBold'' he was a carrot top, while Creator/DarrenCriss has black hair.
* AdaptationalHeroism: He put Kara and Barry under his spell as a SecretTestOfCharacter rather than out of malice, as opposed to the original Music Meister, a CardCarryingVillain who, despite having [[AlasPoorVillain a sympathetic origin]], had [[LackOfEmpathy no empathy]] and was really only out to get rich.
* AdaptationalSuperpowerChange: The original Music Meister put his victims into a hypnotic trance where they would sing and be [[BrainwashedAndCrazy under mind control]]. This Music Meister induces a coma in his victims, where they enter a shared dream world where their [[PowerNullifier 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 [[PowerParasite acquires the powers]] of those under his spell.
* AffablyEvil: During the entire crossover he's very friendly and cheerful to everyone. It makes sense once it turns out he isn't that evil.
* AlliterativeName: '''M'''usic '''M'''eister.
* AmbiguouslyEvil: 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.
* AmbiguouslyHuman: 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.
* AmbiguousSituation: It's unclear just how he managed to end up on Earth-38, since he apparently can't actually travel between Universes.
* ArcVillain: Of the 2017 crossover between ''Series/{{Supergirl|2015}}'' and ''Series/{{The Flash|2014}}''
* BlueAndOrangeMorality: 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.
* CanonImmigrant: Technically. He debuted on ''WesternAnimation/BatmanTheBraveAndTheBold'' before making his way onto CW's Arrowverse, but he has yet to make an appearance in the source material.
* CapturedOnPurpose: 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.
* CastingGag: Played by Grant Gustin & Melissa Benoist's [[{{Series/Glee}} former coworker]].
* CivvieSpandex: This Music Meister dresses in mostly normal looking clothes, unlike his ''WesternAnimation/BatmanTheBraveAndTheBold'' counterpart who has a notorious habit of [[InstantCostumeChange frequently changing outfits]].
* CompositeCharacter: His [[SuperPowerLottery god-like powers]] and prankster nature make him more like Mr. Mxyzptlk.
* EarlyBirdCameo: He's mentioned in the possible future visited by Barry before appearing in person in the crossover.
* EvilIsHammy: He's very theatrical and cheeky, much like his animated counterpart.
* EvilWearsBlack: Music Meister dresses in various shades of black, save a red handkerchief.
* GoodAllAlong: Ultimately, the reason he did everything was to help the heroes deal with their personal problems.
* GreatGazoo: Shows up out of nowhere to teach Kara and Barry a lesson, and then vanishes without explaining who or what he is.
* HumanoidAbomination: 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.
* HypnoticEyes: He can send people into a coma. When he does his eyes flash.
* InexplicablyAwesome: He refuses to explain what he is.
* InNameOnly: He shares virtually no common traits with the original Music Meister; in fact, he seems to take more after Mr. Mxyzptlk than his namesake.
* LotusEaterMachine: He sends Kara and Barry into a musical film fantasy.
* MagicEye: His eyes possess the ability to send people into a coma.
* MediumAwareness: He claims to be aware of everything, and does have knowledge of cultures throughout TheMultiverse.
* MovieSuperheroesWearBlack: His animated counterpart had multiple costumes colored green and purple. Here, he wears a black suit.
* MusicalWorldHypotheses: 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.
* TheMusicMeister: In a different way to the TropeNamer 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).
* MysteriousPast: Nothing is known about what he is, or where he's from, and he refuses to shed any light on these questions.
* NiceGuy: While he's a SinkOrSwimMentor with enigmatic motives, he's a ShipperOnDeck 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.
* TheOmniscient: He's aware of what's happening to characters on both Earths-1 and 38, implying he's also aware of the entire Multiverse.
* PowerNullifier: While in the Music Meister's coma, superheroes will have [[BroughtDownToNormal lost their powers]].
* PowerParasite: 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.
* RealityWarper: He displays the ability to teleport, and is implied to be a 5th-Dimension Imp like Mr. Mxyzptlk (or something else entirely).
* RoguesGalleryTransplant: In his initial appearance on ''WesternAnimation/BatmanTheBraveAndTheBold'', he was a Batman villain.
* ShipperOnDeck: He plays Cupid for Barry & Iris and Kara & Mon-El. Why? Who knows?
* TheSpook: 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.
* SuperPowerLottery: This Music Meister displays an impressive array of powers. In addition to his traditional [[TheMusicMeister music inducing hypnotism]], he's also a PowerParasite, a PowerNullifier, displays MediumAwareness, and uses {{teleportation}}.
* TallDarkAndSnarky: As played by Darren Criss, he's pretty cheeky when he escapes to Earth-1.

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.
* EmotionEater: Grief makes it stronger, and its victims tend to be those who are grieving.
* EvilLivingFlames: He initially appears as a mass of black fire that Team Flash initially thinks is being activated by a metahuman, before they realize that [[ItCanThink the fire itself is alive]].
* FlyingFirepower: After gaining a humanoid form he gains a powerset similar to Firestorm.
* InNameOnly: 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.
* KillItWithFire: Its victims are burned to a crisp with its blue fire, leaving behind only a charred skeleton.
* KnightOfCerebus: His appearance marks a shift in tone from superhero fiction into outright horror, something [[WordOfGod Eric Wallace]] specifically noted.
* NoSell: Nothing that Team Flash uses against him has any effect whatsoever. He's ultimately defeated after Frost is [[SuperEmpowering empowered]] in the M.A.C. device so that she effectively becomes an anti-Deathstorm living weapon.
* ObviouslyEvil: Let's see, it has a [[FlamingSkulls flaming]] [[SkullForAHead skull for a head]], has a [[DarkIsEvil dark colour aesthetic]], is [[EmotionEater fueled by grief]], and has [[NamesToRunAwayFrom "''Death''"]] in its name. Yeah, we've got our villain.
* OutsideGenreFoe: 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.
* SerkisFolk: 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.
* StalkerWithACrush: 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.
* TechnicolorFire: Its fire is black and blue rather than red, and is said to be a product of cold fusion.
* TruerToTheText: This Deathstorm has a lot in common with his appearance in ComicBook/BlackestNight (which is itself referenced twice in the arc), compared to Firestorm's Earth-2 counterpart who called himself "Deathstorm" seen back in season 2.

** 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.
