** [[ComicBook/{{Catwoman}} Selena Kyle]] is a straighter example of this trope. Like the show's second take on the Joker, she's friends with Bruce when they're young, but unlike him, she was a relatively nonviolent thief when she first became friends with him, and doesn't get any more violent when she gets older. [[DatingCatwoman They even date]] for awhile [[ToyShip when they are teenagers.]] When Bruce comes back from training and officially becomes Batman, he catches her stealing a diamond, but instead of trying to arrest her, he finds her later and tells her to put it back. She just laughs, and he doesn't try to force the issue when she doesn't listen to him. His attitude toward her crimes makes sense, though, because [[DependingOnTheWriter unlike some past versions of Bruce,]] the Bruce in this series doesn't have a problem with being friends with people who he knows are non-violent criminals, and doesn't even have a problem with stealing, himself, if it is from criminals that are hurting people.

*** Gul Dukat considered Sisko a friend for most of the series but it was not reciprocated. Dukat sometimes acted as if Sisko was just pretending to hate him to keep up appearances, although it was clear that he was genuine (what with Dukat being a mass-murderer).

** ''Series/BetterCallSaul'' depicts the lawyers of Albuquerque's top law firms as a close-knit fraternity, even those who are representing opposing plaintiffs in court.

** On the few occasions we see Hacker interacting with members of the opposition party, it's made pretty clear that for all the noise and bluster in the House and differing political views, there's no real malice there. Hacker at one point notes that the other party is just the Opposition; the real enemy for both is the civil service.

* A strange example in ''Series/OnceUponATime''. [[spoiler:Nick[=/=]Jack[=/=]Hansel]] is actually Henry's best friend, but Henry doesn't remember because of the curse and only knows him as an insane SerialKiller. [[spoiler:Hansel]] talks to Henry in a friendly tone when he is holding him prisoner and reminisces about their adventures together, but Henry just thinks he's delusional. He even apologises before knocking Henry unconscious, saying "Sorry man, I've been tied to enough trees with you to know those repose aren't going to hold."

-->'''Hacker:''' We've grown quite fond of each other, haven't we? [[StockholmSyndrome Like a terrorist and a hostage.]]\\

* ''Series/AvataroSentaiDonbrothers'': The Noto generals are defined by a burgeoning curiosity for specific tendencies of the human experience, [[VillainTakesAnInterest an itch that various members of the Donbrothers appear to scratch]]: Sonoi's interest in purity has developed into a friendly rivalry with the simultaneously caustic-yet-pure Taro, Sonoza has become interested in Haruka's growth as a manga author in his pursuit of emotion, Sononi is captivated by Tsubasa's love for his lost girlfriend and Don Murasame finds [[spoiler: the two Jiros]] so intriguing he's willing to defy his Mother's orders just to converse with them. These colliding interests and hobbies cause the Noto to [[GoKartingWithBowser fraternize with their enemies as often as raise their weapons to them]], an arrangement both factions frequently lampshade; though [[SuspiciouslySpecificDenial it's solely to learn about the enemy and nothing else]]. It's such a positive relationship that the Noto Council took notice of the mingling and introduced PoliticalOfficer Sonoshi to try ([[spoiler:[[EnemyMine and fail]]]]) to break it apart.

* In ''Series/JukenSentaiGekiranger'', Rio and Mele [[EnemyMine pull the Rangers' asses out of the fire]] so many times that [[spoiler:it doesn't surprise anyone when they [[HeelFaceTurn turn good in the end]]]].

** The Doctor and the Master, though how friendly they are has varied during the ({{long|Runners}}) run of the series. He once introduced the Master as "my best enemy" in a clear parallel to the concept of best friends. They did break up once — in [[Recap/DoctorWhoS14E3TheDeadlyAssassin "The Deadly Assassin"]], the Master has gone [[CameBackWrong so much off the rails]] that the Doctor declares he's over him and he now genuinely wishes him dead — but he warmed up to him again after the Master got himself a new body and then gave ''him'' a new body. Even Thirteen, who views the Master as her BerserkButton has time for playful banter with her best enemy.

** On ''Series/ForThePeople'' the main characters, three rookie prosecutors and three new public defenders, gradually become more friendly just through regular proximity. As one of the points out, they actually become too close as they are more wiling to go easy on each other or take aggressive courtroom tactics personally, which affects their performance and compromises their duties to their clients[=/=]the state.

* In ''Series/Hawkeye2021'', Yelena Belova came to New York wanting to murder the title character for supposedly killing her 'sister' Natasha, the Film/{{Black Widow|2021}} (which he didn't, even if [[Film/AvengersEndgame he was there when she died]]). Hawkeye's fan-turned-protege Kate Bishop is all for standing in Yelena's way. And both times they share a moment, it's clear that even in opposite sides, again everything is there for a new Hawkeye/Black Widow friendship - first, Yelena breaks into Kate's apartment and they talk a lot before it comes to 'here to kill Clint Barton'; and then, as Kate tries slowing Yelena down before she gets to Clint, they compliment each other's attacks, with Kate even saying "Stop making me like you!".

** Giles and his EvilFormerFriend, Ethan Rayne. Despite the fact that Giles immediate reaction to seeing Ethan is to beat him up with his bare hands, Ethan still tends to act like Giles is something of a friend, never once tries to fight him and is genuinely happy when he convinces Giles to get drunk with him.

** In Season 7, a new vampire says delightedly, "I was afraid to talk to you in high school, and now we're, like, mortal enemies. Hey, wouldn't it be cool if we became nemeses?" And a bit later: "I'm sorry if I overstepped my bounds. I'm just new to this whole mortal enemy stuff."
