History ArchEnemy / Arrowverse

* Kara Danvers has many enemies, but by virtue of being an AllLovingHero, she doesn't have the kind of personal hatred for her worst ones that Oliver and Barry have for theirs. However, she openly calls Leslie Willis, a.k.a Livewire, her nemesis.

* CADMUS as a whole serves as this to the Department of Extra-Normal Operations.

** Malcolm Merlyn, Oliver's first personal enemy, and the one who was most similar to him as an EvilCounterpart as a man who lost himself to the darkness; its a small wonder why Merlyn calls himself the "Dark Archer". Being responsible for sinking the ''Queen's Gambit'', and leaving Oliver stranded on Lian Yu for years, Malcolm plays a huge role in ruining Oliver's life and setting him on the path of becoming the vigilante he is today. In their rivalry, Merlyn has been responsible for the deaths of three important people in Oliver's life, and manipulating Thea against Oliver multiple times. Even after he and Oliver came to an EnemyMine against Ra's al Ghul, Merlyn ended up [[HeelFaceDoorSlam betraying Oliver to H.I.V.E.]] after he gets humiliated from being beaten in a League challenge, resulting in Oliver cutting off Merlyn's hand and stripping him of the title of Ra's al Ghul. Things are so personal that, during said duel, Malcolm makes it clear that the only way their feud will end is when one of them is dead.

* Felicity's dubs the Bug-Eyed Bandit, Brie Larvan, as her personal nemesis after she gives her a run for her money in hacking. She also has a rocky relationship with her father, Noah Kuttler a.k.a the Calculator.

!! ''The Flash''

** He also had a SitcomArchNemesis in Ralph Dibny. Prior to the start of the series, when Barry was a rookie CSI, he and Ralph were working on the same case: a woman was stabbed to death and her husband was the prime suspect. Despite that, there was no proof he committed the crime -- until Ralph planted a knife with his fingerprints and the victim's blood to convict him, thoroughly convinced that he was guilty. Barry, off-put by the similarity the case had to his mother's death, analyzed the knife, found the evidence was tampered with, and promptly got Ralph kicked off the force. Years later, he's a down-on-his-luck PI who has let himself go and when he and Barry meet again, they prove time does ''not'' heal all wounds, as the two unabashedly still hate each other. All this being said, Ralph and Barry become friends as season six progresses and the mutual loathing Barry and Ralph had for each other was nowhere near as personal and vicious as most of the examples on this page.

* Lena Luthor has Morgan Edge. After Lena outbid Edge for Katco he swore to crush his business rival. After multiple attempts to frame and murder her, the feeling is more than mutual.

** Dinah quickly gains another nemesis in the form of Laurel Lance's Earth-2 counterpart Black Siren.

Years later, he's a down-on-his-luck PI who has let himself go and when he and Barry meet again, they prove time does ''not'' heal all wounds. The two unabashedly still hate each other and it takes every bit of self control for them not to beat each other faces in, even after they come to an understanding at the end of Ralph's debut episode. All this being said, the mutual loathing Barry and Ralph have for each other is nowhere near as personal and vicious as most of the examples on this page.

* Aside from the hatred for Eobard Thawne he shares with Barry, Cisco Ramon originally had Hartley Rathaway, a.k.a the Pied Piper, but after Barry alters the events of ''The Sound and the Fury'', Hartley undergoes a HeelFaceTurn and becomes an ally. After donning the "Vibe" moniker, Cisco's arch foe becomes "Killer Frost", the dark persona of his best friend, Caitlin Snow, until Iris West convinces Killer Frost to work with Caitlin and Team Flash instead of against them.

** Also, even tough they have only faced each other once so far, Rick Malverne is Supergirl's only enemy to truly get under her skin by kidnapping Alex and threating her life to make Supergirl his pawn, with her unable to find a way to counter his various contingencies.

** Darhk's colleagues in the Legion of Doom also serve as this to the Legends, with Vixen having her sights set on the Reverse-Flash for killing [[FirstLove Hourman]], while Thawne thinks himself a {{Foil}} to the Atom, and Captain Cold trying to persuade Heat Wave back into a life of crime.

* The Legends and the Legion of Doom. For more specific enemies, Sara hates Damien Darhk [[spoiler:for killing Laurel]], and Amaya has her sights set on Eobard Thawne for killing her FirstLove Rex Tyler, while Thawne thinks himself a {{Foil}} to Ray.

* Aside from the hatred for Eobard Thawne he shares with Barry, Cisco Ramon originally had Hartley Rathaway, a.k.a the Pied Piper, but after Barry alters the events of ''The Sound and the Fury'', Hartley undergoes a HeelFaceTurn and becomes an ally. After donning the "Vibe" moniker, Cisco's arch foe becomes "Killer Frost", the dark persona of his best friend, Caitlin Snow.

** Rhea, Queen of Daxam, [[spoiler:and Mon-El's mother. She despises Kara, blaming her for Mon-El's decision to stay on earth and rejection of his culture's values. It's all but stated that the Daxamite invasion was in part to spite her enemy, and eventually led to Kara and Mon-El's [[StarCrossedLovers forced separation]]]].

* Barry has almost as many as Oliver.

** Leonard Snart, a.k.a Captain Cold, is identified as the Flash's "nemesis" by Thawne. He was certainly a persistent and dangerous foe, being the first to utterly defeat Barry, then torturing Cisco to learn the Flash's identity, to finally tricking Barry into an alliance just so he could betray him. However, their animosity declined after Barry saved Snart's sister from their abusive father, and [[spoiler:Snart ended up pulling a HeroicSacrifice for the Legends]] with he and Barry only truly becomes FriendlyEnemies when Barry time travels to before [[spoiler:his death]] to ally with him.
** Earth-2's Hunter Zolomon, a.k.a Zoom, who pulled the same trick as Thawne did by impersonating "Jay Garrick" and presenting himself as an ally all so he could steal Barry's speed to cure himself of Velocity poisoning. As Zoom, he beat the crap out of Barry several times, once breaking his back and humiliating him in front of all of Central City. Then there's what he did to the rest of Team Flash: he kidnapped Jesse Wells to blackmail Harry into helping him, kidnapped Wally to force Barry to give up his speed, and then kidnapped Caitlin to invoke StockholmSyndrome on her. And, for the final finishing touch, he murdered Henry Allen ''in the very same spot where Eobard Thawne murdered Nora Allen'', right in front of Barry's eyes. After that, Barry wants him deader than dead and looked very ready to do the deed, inspiring a deep hatred in him that not even Thawne was capable of.

* Savitar is this to Team Flash as a whole, having found a way to irk off every one of them. Case in point, [[spoiler:in a possible future, after he murders Iris, he cripples Wally, corrupts Caitlin beyond recovery, and more-or-less breaks Team Flash until Present!Barry gets them back together.]]

** Slade Wilson, a.k.a Deathstroke, who served as a much more personal enemy. At first friends, Slade was set on a [[ImplacableMan never-ending vendetta]] to ruin Oliver's life, since he blames Oliver for causing Shado's death, the most crushing blow being [[spoiler:when he killed Oliver's mother in front of his eyes]]. However, Oliver has more-or-less accepted the fact that what happened with Slade was partially his fault for not telling him the truth about Shado's death when he had the chance, and is happy to leave Slade imprisoned instead of killing him due to that and their formerly close relationship.

*** Darhk was also Ra's al Ghul's nemesis, having been his friend before they became rivals for the title of "The Demon's Head". While they havn't interacted in the proper sense, Ra's entire plan to destroy Star City was not only to ensure Oliver's ascension as his heir, but to kill Darhk as well.

* Damien Darhk is this to all of Team Arrow for, amongst over crimes, threating Laurel to get Quinton to join H.I.V.E., ruining Oliver's mayoral campaign, crippling Felicity and leaving her paraplegic, kidnapping Oliver's illegitimate son William, and turning Diggle's brother against him. After he [[spoiler:kills Laurel purely out of spite]], it doesn't take long for all of Team Arrow to bitterly hate him and want him dead above all else.

** Savitar is this to Team Flash as a whole, having found a way to irk off every one of them. Case in point, [[spoiler:in a possible future, after he murders Iris, he cripples Wally, corrupts Caitlin beyond recovery, and more-or-less breaks Team Flash until Present!Barry gets them back together.]]

** Earth-2's Hunter Zolomon, a.k.a Zoom, who pulled the same trick as Thawne did by impersonating "Jay Garrick" and presenting himself as an ally all so he could steal Barry's speed to cure himself of Velocity poisoning. As Zoom, he beat the crap out of Barry several times, once breaking his back and humiliating him in front of all of Central City. Then there's what he did to the rest of Team Flash, Barry's loved ones: he kidnapped Jesse Wells to blackmail her father Harry into helping him, kidnapped Wally West to force Barry to give up his speed, and then kidnapped Caitlin Snow to invoke StockholmSyndrome on her, traumatizing her and leaving her with PTSD. And, for the final finishing touch, he murdered Henry Allen ''in the very same spot where Eobard Thawne murdered Nora Allen'', right in front of Barry's eyes. After that, Barry wants him deader than dead and looked very ready to do the deed, inspiring a deep hatred in him that not even Thawne was capable of. While Thawne might be his most personal enemy, Zolomon is his most hated, and rightfully so.

** Savitar. [[spoiler:In a possible future, he murders Iris, cripples Wally, helps further corrupt Caitlin, and more-or-less ''breaks'' Team Flash. But what makes everything worse is his true identity: he's a time remnant of '''Future Barry Allen''', DrivenToVillainy after being rejected by his loved ones, including his progenitor, for not being the "true" Barry. Already grieving over Iris' death, this Barry went insane, and, in an attempt to remove his ability to feel emotional pain, went back in time and became the Savitar of legend, intent on maintaining the StableTimeLoop that ensures his existence by killing his OneTrueLove. Whereas Thawne is his most personal enemy and Zolomon his most hated, Savitar is undoubtedly his worst enemy, because [[HisOwnWorstEnemy one can't get a worse enemy than themselves]]]].

* Kara Danvers has many enemies, but by virtue of the tone of her show and her own personality, she doesn't have the kind of personal hatred for her worst ones that Oliver and Barry have for theirs.
** Kara openly calls Leslie Willis, a.k.a Livewire, her nemesis.

** Non, her EvilUncle, and his Coluan lover Indigo, a.k.a. Braniac 8.
** Queen Rhea of Daxam, Mon-El's mother, who blames Kara for "poisoning" her son's mind.

* Though their quarrel is entirely off-screen, ComicBook/LexLuthor and ComicBook/{{Superman}} are still recognized as arch foes by the public of Earth-38.

* Oliver Queen, through his many disguises, has earned the mutual ire of many dangerous foes, but the biggest in his RoguesGallery are;

*** It's also worth noting that Oliver and Slade are also part of a line of "Deathstrokes" and archers that share an animosity. Before them, it was Yao Fei and Billy Wintergreen, and after them it will be Connor Hawke and Grant Wilson.
** To avenge his father's death at Oliver's hand, Adrian Chase, as Prometheus, terrorizes Star City and kills several innocent people, recruits people into turning against Oliver, manipulates Oliver into killing Felicity's boyfriend, psychologically tortures him to the breaking point, and eventually forces Oliver to turn the city against his superhero identity, branding Green Arrow a criminal, all while under the guise of FalseFriend buttering him up to gain his trust, aiding him as one of his closest confidants within his administration and even helping Diggle get out of military prison. Once the charade is broken, the two don't even try to hide how much they hate each other, making it very clear that their war will only end when one of them is dead. In fact, Oliver is even willing to [[EnemyMine ask for help]] from Malcolm and Slade, he's that desperate to beat Chase.
* Floyd Lawton, a.k.a Deadshot, was this to John Diggle for killing his brother, Andy. However, His NobleDemon tendencies later endeared him to Diggle and they eventually came to an understanding that [[spoiler:leads Lawton to sacrifice his life to get Diggle home to his family]]. [[spoiler:Ironiclly, Andy would become Diggle's foe after it was revealed he faked his death to join H.I.V.E.]]
* Malcolm Merlyn is also high on many people's hit list, but is chiefly a menace too...
** Moira Queen, who he had an affair with and then betrayed him when she realised the full scope of his madness.
** Nyssa, who dedicated her life to bringing Malcolm down ever since he killed Sara. When Malcolm becomes Ra's al Ghul, Nyssa did everything in her power to overthrow him, even destroying the Lazarus Pit to spite him. Eventually, Malcolm came to hate Nyssa too, willing to betray a truce between them when she had offered a cure for his daughter's life. In the "Doomworld" altered reality, the only thing Malcolm used the Spear of Destiny to do besides benefit his needs was banish Nyssa to a closeted life.

*** Darhk is also Ra's al Ghul's nemesis, having been his friend before they became rivals for the title of "The Demon's Head". While they havn't interacted in the proper sense, Ra's entire plan to destroy Star City was not only to ensure Oliver's ascension as his heir, but to kill Darhk as well.

After that, Barry wants him deader than dead and looked very ready to do the deed, inspiring a deep hatred in Barry that not even Thawne was capable of.

* Joe West had the Mardon brothers. Clyde killed his partner, and he eventually killed Clyde in defence of Barry. Unfortunately, Mark Mardon did not take the death of his little brother well, and goes gunning for Joe until Barry alters the timeline and Mark's vendetta goes unresolved.
* Aside from the hatred for Eobard Thawne he shares with Barry, Cisco Ramon originally had Hartley Rathaway, a.k.a the Pied Piper, but after Barry alters the events of ''The Sound and the Fury'', Hartley undergoes a FaceHeelTurn and becomes an ally. After donning the "Vibe" moniker, Cisco's arch foe becomes "Killer Frost", the dark persona of his best friend, Caitlin Snow.
** Though PlayedForLaughs, Cisco also treated Russell Glosson, a.k.a the Turtle, as his biggest enemy, having partaken in a "secret war" against him for months, but Glosson [[UnknownRival doesn't even though Cisco exists]].
* General Wade Eiling was the archenemy of Firestorm, but only the Martin Stein/Ronnie Raymond fusion. After the Reverse-Flash hands Eiling over to Grodd, Eiling turns his resources towards stopping Grodd instead of further hunting Firestorm.
* In the "Flashpoint" timeline, Wally West had Edward Clariss, a.k.a the Rival, for an arch foe. However, in the main timeline, he has yet to develop a personnel animosity with an adversary.

* Mari McCabe had her sister, Kuasa, and then Benatu Eshu.

* Kara openly calls Leslie Willis, a.k.a Livewire, her nemesis.

** Also, even tough they have only faced each other once so far, Rick Malverne is Supergirl's only enemy to truly get under her skin by kidnapping Alex and threating her life to make Supergirl his pawn, with her unable to find a way to counter his varies contingencies.

* Vandal Savage is this to Hawkman, Hawkgirl and Rip Hunter.

* John Constantine had Papa Midnite.

* Next to her father, Thea's biggest enemy is Lonnie Machin, a.k.a Anarky.
* Vandal Savage is this to Hawkman, Hawkgirl and Rip Hunter.

* In the "Flashpoint" timeline, Wally West had Edward Clariss, a.k.a the Rival, for an arch foe. However, in the main timeline, he has yet to develop a personnel animosity with an adversary.

* Dinah Drake had Sean Sonus, for killing her cop partner and lover. She spent three years hunting him on a RoaringRampageOfRevenge, [[spoiler:until she killed him]].
* Abra Kadabra is this to Gypsy for killing her former lover among many other people. He also implies that he will one day become one for the Flash.

** Oliver Queen, through his many disguises, has earned the mutual ire of many dangerous foes, but the biggest in his RoguesGallery are;

*** Even his own daughter, Thea, who he brainwashed into [[spoiler:killing Sara Lance]] in his gambit to end his debt to Ra's al Ghul, which also deepened Nyssa's hated for Merlyn, has it out for him. Thanks to his refusal to give up leadership of the League for her and handing Oliver's son William over to Damien Darhk, she appears to have rejected him and he appears to have gone full-blown villain. They do face off in combat, but he won't kill her.
** Detective Quentin Lance had Barton Mathis, the Dollmaker.
** Barry has almost as many as Oliver.
*** Eobard Thawne, a.k.a the Man in the Yellow Suit a.k.a the Reverse-Flash. Thawne murdered Barry's mom, framed his dad for it, and then manipulated Barry's life under the guise of "[[TeamDad Dr. Harrison Wells]]". He is Barry's most personal enemy, and their destinies are so intertwined that one cannot exist without the other, thus they will never be fully rid of one another -- a fact that only makes them hate each other more.

*** After Snart [[Series/LegendsOfTomorrow leaves with the ''Waverider'' crew]], Grodd takes his place as Barry's top non-speedster enemy. By the time "Attack on Gorilla City" happens, Grodd has forgone all former attachments and his sole concern is getting revenge on Barry for exiling him to Earth-2 by any means necessary. Barry even contemplates killing Grodd to end his evolving threat, which Grodd even encourages him to do, seeing it as the only way to "end it".
** Joe West had the Mardon brothers. Clyde killed his partner, and he eventually killed Clyde in defence of Barry. Unfortunately, Mark Mardon did not take the death of his little brother well, and goes gunning for Joe until Barry alters the timeline and Mark's vendetta goes unresolved.

** Kara openly calls Leslie Willis, a.k.a Livewire, her nemesis.
*** Maxwell Lord was also a recurring menace to Supergirl in her early career, but hostilities between them decreased as time went by.
*** Also, even tough they have only faced each other once so far, Rick Malverne is Supergirl's only enemy to truly get under her skin by kidnapping Alex and threating her life to make Supergirl his pawn, with her unable to find a way to counter his varies contingencies.
** Next to her father, Thea's biggest enemy is Lonnie Machin, a.k.a Anarky.
** Vandal Savage is this to Hawkman, Hawkgirl and Rip Hunter.
** J'onn J'onzz views the entire White Martian race as this for their part in his kinds extinction, but he begins to lighten up to them after meeting M'gann M'orzz.
