* Xavier and {{Magneto}} of ''ComicBook/XMen''...
** An interesting variant occurs during the "Acts of Vengeance" crossover, where Magneto decides to ignore the stated purpose and kill the RedSkull. Red Skull launches into a NotSoDifferent [[http://i.imgur.com/cc2oPqo.jpg speech]], essentially taunting Magneto about the fact that his quest for mutant supremacy is quite similar to the [[{{Nazi}} Red Skull's own ideology]]. In the end Magneto spares his life but seals him inside an underground room filled with food and water.
** Magneto to humans. Humans want the mutant species either isolated, tagged like cattle, or just outright eradicated. Magneto simply swaps "human" and "mutant" in his rhetoric.
** Or Comicbook/{{Cyclops}} and Prof. X. After taking charge of the X-Men, Scott has begun to keep secrets and make unilateral decisions, the same things that made him kick out Xavier. This came to a head in ''ComicBook/AvengersVsXMen'', where a Phoenix-possessed Cyclops killed Xavier after trying to conquer the world and make it into a mutant Utopia. Now he's on the run and leading his own team of mutant outlaws.
*** Ironically, in more recent years Cyclops have been compared to Magneto more so than anyone else. Despite being Professor X's top student, his philosophies and actions actually fell more aligned with Magneto's. Magneto himself even directly says so before the climax of the aforementioned event.
** Then there's Emma Frost to ComicBook/{{X 23}}, who explains to the latter the reason she wants her to leave Xavier's Institute is because Emma sees in her the same capability to hurt (and kill) those close to her that she has as a young girl. However, Emma also points out one big difference, whereas she would do this willingly, X would likely have no choice in the matter due to her conditioning to a "[[BerserkButton trigger scent]]."
*** Ironically, Emma later gives one to Cyclops at the beginning of Laura's solo series, pointing out that involving her with ComicBook/XForce was no different than what the Facility was using her for.
*** ''CaptainAmerica'' of all people gets called out on this, too: In ''Target: X'' he intends to turn Laura over to ComicBook/{{SHIELD}} to be tried for her crimes, despite Comicbook/{{Daredevil}}'s attempts (as her lawyer) to warn him that S.H.I.E.L.D. won't care about justice, and will only see her as a weapon to use themselves. Fortunately, Steve realizes Matt is right before he can actually go through with it.
*** Also {{X-23}} and Vampire Jubilee realize they have much in common, with X-23 having to struggle with finding herself and the trigger scent and Jubilee struggling to control her newfound blood lust. They get along [[HoYay/XMen really well though]].
*** X-23 also had hero-to-hero example when she joined AvengersAcademy -- she was afraid her DarkAndTroubledPast and few mental issues it gave her will make her into an outcasts, only to learn many of the students also had problems developed by their past traumas.
*** And X-23 again, with her psychotic ex-handler, Kimura: Both were severely physically and emotionally abused and bullied in their formative years. But that's about where it ends, as Laura makes an ongoing effort to heal, while Kimura makes it her FreudianExcuse to inflict pain on others.
*** [[RunningGag X-23 and Daken]] are a ''lot'' alike: Offspring of ComicBook/{{Wolverine}}, both raised by some very bad people, both highly-trained and dangerous killers. Despite their relationship being antagonistic, after Daken's usual bouts of double-crossings are out of the way when they first meet [[FriendlyEnemies they actually get along]] and [[EnemyMine work together fairly well]]. When they part ways Laura is one of the ''very'' few people Daken genuinely respects, in large part because they are so alike.
* ComicBook/{{Runaways}} also have it with The Pride, their parents.
** Later there was conflict between them, and the students and faculty of Avengers Academy, full of this trope from very begining, which culminated in two groups trying to use magic to better understand each other and ending up experiencing how much they really have in common.
* That he is NotSoDifferent from his greatest enemies, especially SelfDemonstrating/TheJoker, is repeatedly shown to be one of Franchise/{{Batman}}'s greatest fears. It's not an unfounded idea either; he may not be cruel or a murderer, but he's still not the sanest guy.
** ''ComicBook/TheKillingJoke'' has the Joker try to prove this to Batman in his own psychotically twisted way. In the end, after Batman proves that the Joker's biggest point, that '''everyone''' was just like him, false, he and Joker share a big metaphorical NotSoDifferent moment, and end the book laughing maniacally together. One of the Joker's primary goals is to prove that everyone else is NotSoDifferent from him. He tried it in ''The Killing Joke'', and he tried it again near the end of ''ComicBook/BatmanNoMansLand'' [[spoiler: when he shot Gordon's wife Sarah]].
** Mr. Zsasz gave Batman one of these speeches during the ''ComicBook/{{Knightfall}}'' crossover. His main point was that they both hunted people.
** The whole point of ''Comicbook/{{Arkham Asylum|ASeriousHouseOnSeriousEarth}}'' is about questioning Batman's sanity and showing him being NotSoDifferent than his villains.
** Batman himself is also regularly used as the unsavoury person from whom the hero is not so different, when other heroes accuse their Bat-raised team members.
*** [[ComicBook/BirdsOfPrey Oracle]] (Barbara Gordon): while Barbara is more emotionally stable than Bruce and is actually willing to let people get close to her without being compelled to push them away, she can be every bit the {{manipulative|Bastard}} ControlFreak that he is. In an early ''ComicBook/BirdsOfPrey'' storyline, ComicBook/{{Huntress}} called out Barbara on her secret attempts to "fix" Huntress (Huntress took issue with being considered "broken") and left the team. As she left, she accused Barbara of turning out to be a manipulative jackass just like Batman.
*** ComicBook/{{Nightwing}} (Dick Grayson): as the leader of several groups of heroes, he's occasionally being judged as becoming way too much of a drill sergeant by less, ah, obsessive heroes. Happened a couple of times in The Titans and Outsiders.
*** Tim Drake: more prevalent in earlier years, when Tim's CrazyPrepared ProperlyParanoid tactics hadn't come to be as accepted by his friends, and they tended to blame the fact that he could be distant, manipulative, and distrusting on Batman. Nowadays they know better.
*** ''Doesn't'' happen with as much regularity to the members of the Batfamily who would most rejoice in the comparison, Cassandra and Damian, both of whom ''want'' to become Batman.
*** With the ComicBook/{{New 52}} reboot in effect, this trope can apply to Batman and [[TheFlash Barry Allen]]. Both heroes have been orphaned at a young age, victims of circumstances beyond their control. Their respective tragedies are part of what drives them to be heroic.
* ComicBook/IronMan has been compared to DoctorDoom quite a bit. Especially since [[WhatTheHellHero his behavior in]] ''Comicbook/CivilWar''. It really doesn't help when Doom discovers that the technology behind their PoweredArmor is nearly identical.
* Doom and Reed Richards of the Comicbook/FantasticFour. They are two of the most brilliant supergeniuses in the Marvel universe, and are in many ways similar in personality. The fact that they were even more similar in grad school has also been explored at length, [[ComicBook/WhatIf including at least one alternate universe with Doom as a hero and the Fantastic Four as supervillains]] blaming Doom for sabotaging their ill-fated trip into space...because ''Reed'' was too proud to heed ''Doom's'' warning that his spaceship didn't have proper shielding.
* ComicBook/ThePunisher gets a lot of these, [[KilledMidSentence although he usually just shoots the guy before they get beyond "we're no--".]]
** A quadriplegic mob boss goes on a rant about how the Punisher is a evil monster who is no better than her. Frank's response:
-->''[[ShutUpHannibal Tell me something]] [[GenreSavvy I don't know]].'' [[Awesome/ThePunisher (throws grenade)]]
* Here's a weird one: In the first issue of the new ''Comicbook/{{Azrael}}'', Az is on the hunt for a serial killer. During the course of his investigation, he realizes the killer is targeting people who allowed a horrible crime to happen. When they finally confront each other, the Avenging Angel gives ''himself'' the NotSoDifferent speech, and allows the killer to depart.
* In the Franchise/{{Archie|Comics}} ''Comicbook/SonicTheHedgehog'' comics, [[EvilTwin Scourge]] often brings this up to convince Sonic to be 'evil' like him. As he puts it, "[[SelfDemonstrating/TheJoker All it takes is one bad day]], and you'd be just like me." Throughout the series they compare themselves to one another (in one issue, Sonic says something along the lines of "My evil 'twin' [[spoiler: conquered a planet on his own.]] What do you think will happen if I let loose?")
** Promptly after the aforementioned Scourge quote, Sonic catches him off-guard with a counterattack, and while he's on his back, proceeds to throw the same thing right back at him, saying the real reason he hates Scourge is that if he only had a little kindness and decency, he'd be just like Sonic.
* The Mist (Nash) from the 1990s ''Comicbook/{{Starman}}'' series gave this speech to Jack Knight, citing the fact that they were both carrying out the roles because of their fathers. Jack goes out of his way to prove her wrong by being nice to her father, the original Mist.
* ''TheIncredibles'' comic has this when Mirage and Elastigirl have to work together on a mission, Mirage bringing up the point that Helen ended up having to lie to her family about a new adventure as well as having been the [[DatingCatwoman ex-girlfriend of the supervillain]] they're going after.
* In ''ComicBook/BlackestNight'', Saint Walker tries to connect with Atrocitus by pointing out that he has lost his family as well, so he can understand his pain. However, Atrocitus retorts that Saint Walker lost his family in an accident, while Atrocitus' family was murdered.
* [[spoiler:dWARf!/Fleshmaster]] calls this between himself and Comicbook/{{Empowered}}, but she proves him wrong. Also, Sistah Spooky claims this to be true about her then-partner Mindf??k and Mindf??k's brother. (She just wanted to hurt Mindf??k.) What's really sad is that Sistah is ''right''. Mindf??k had to ''psychically lobotomize herself'' in order to remove her less savory personality traits.
** Another example occurs in volume seven, wherein [[spoiler:Oyuki]] tells [[spoiler:Ninjette]] just how much like her father she is:
-->'''[[spoiler:Ninjette]]''': If you think that I am voluntarily walking into a scenario likely to result in my '''death''' and/or '''dismemberment''' without first getting good and solidly '''buzzed'''...you are '''sadly f**king mistaken'''.
-->'''[[spoiler:Oyuki]]''': By '''sheerest f**king coincidence''', this humble genin has '''often''' heard a remarkably f**king '''similar''' sentiment voiced before battle...by [[spoiler:Kaburagi-san]]'s own f**king '''father''', interestingly enough.
* Deconstructed in [[http://i704.photobucket.com/albums/ww48/comicsando/Quino%20Art/quino2-2.jpg this strip]] from ''{{Quino}}''. For those who don't understand Spanish, it's about how a rich and a third world country woman comment on their food restrictions: While they both claim that they only eat cereals, the rich woman does so to keep her weight, while the poor woman does it because it's the only thing left to eat, and they both complain that their children eat a lot of "trash", like junk food in the rich woman's case and worms, infected water and rotten food in the third world woman's case.
** Played straight in [[http://farm4.static.flickr.com/3595/3330410039_a7fd564eb4.jpg this one]].
* In one classic Comicbook/DoctorStrange story, our hero finds out that the only way to defeat [[EldritchAbomination Shuma-Gorath]] is to play his own game. He puts his morals aside, descends into dark sorcery, destroys Shuma-Gorath and then [[HeroicSacrifice kills himself]] before he can become another Shuma. Fortunately, his ally is able to bring him back.
* Read [[http://www.spideykicksbutt.com/GreenwithEvil/goblinmysteries.html this article]] about NormanOsborn and you'll see that he and [[{{Spider-Man}} Peter Parker]] are not so different.
** Amazingly enough, Spider-man is [[GenreSavvy perfectly aware]] that he and Comicbook/{{Loki}}, [[ManipulativeBastard of]] [[GodOfEvil all]] [[SorcerousOverlord people]], can relate to each other to a degree. After all, they both ''are'' tricksters of a sort, and they both carry [[WithGreatPowerComesGreatResponsibility the burden of great responsibility from their powers]], even if their reasons, methods and ultimate goals are vastly different.
* ''ScottPilgrim'' makes the realization that he's as much of an asshole as his greatest enemy, Gideon Graves. The only difference is that Scott wants to change and be a better person. [[spoiler: This realization causes him to level up and gain a sword called The Power of Understanding which he uses to defeat Gideon.]]
* Done across two different ''dimensions'' by JonathanHickman with Reed Richards, scientist, explorer and leader of ComicBook/FantasticFour from the MarvelUniverse and his evil UltimateMarvel counterpart. Compare the two speeches, both written by Hickman:
-->'''MarvelUniverse Reed Richards:''' So we'll begin here. With you and me. With a new focus for your ongoing and never-ending education. Our curriculum will start at survival and end at the edge of an eternal tomorrow. The rules are simple. I teach one class and it's pass or fail. Welcome to the Future Foundation.
-->'''UltimateMarvel Reed Richards:''' And we'll begin here... with you and me. We're going to have a new focus for my ongoing and never-ending education. The experiment will start with survival and end on milennial tomorrow. My rules are simple. In the dome it's evolve or become extinct. Welcome children. Welcome to tomorrow. I'm sorry. Most of you are not going to make it.
* [[ComicBook/IronMan Tony Stark]] once allowed an anti-war activist/documentarist named [[NoCelebritiesWereHarmed John Pillinger]] to interview him ''knowing'' the man was heavily biased against him. When Pillinger later asked him why Tony agreed to the interview, Tony responded with an ArmorPiercingQuestion that essentially asked if Pillinger's work has actually changed anything at all. When Pillinger admitted that he didn't know, Tony said that he didn't know if anything he has done has changed anything either. The two shake hands before parting, realizing that for all their differences they are both just trying to make the world a better place.
* Invoked in ''[[TheUltimates Ultimate Avengers]]'', where Comicbook/GhostRider convinces Comicbook/ThePunisher to spare his life after pointing out that they both were driven to become [[AntiHero Anti-Heroes]] in order to avenge murdered loved ones.
* The majority of [[Comicbook/TheIncredibleHulk Hulk: Gray]] consisted of Bruce coming to realise that he had a surprising amount in common with his long-time enemy General Ross. Naturally, this being a Hulk comic, he didn't take it well.
* ''ComicBook/RedHoodAndTheOutlaws'': How Red Hood handles his Talon during the Night of the Owls. [[spoiler:He relates to being killed and reanimated as a killer, and not being in control of his own life. The Talon asks Red Hood for help, as he [[ICannotSelfTerminate cannot self terminate]].]]
* In ''ComicBook/MyLittlePonyMicroSeries'' Issue #1 Twilight says that she can sympathies with Jade Singer having to live with extremely high expectations, since being the princess' personal students puts similarly high expectations on her.
* In ''{{Transmetropolitan}}'' Spider Jerusalem has this with many people - as the story progresses all traits he shares with Yelena become more apparent, despite how different they seem at first, he quickly finds he shares the same good intentions with her father, even through socially they behave like polar opposites, and many of his rants are dangerously close to [[PresidentEvil Smiler's]] infamous speech about hating people.
* From ''IncredibleHercules'', [[WarGod Ares]] cannot figure out why people love Hercules considering the latter causes nearly as much death and destruction as Ares. Hercules claims people can see themselves in him since Hercules sees himself and acts more like a normal, flawed man instead of a god or person aspiring for greatness. That and while both love to fight Hercules generally knows when to reign it in while Ares does not care who he fights or how far he goes.
** Ares tries to pull the same with ComicBook/WarMachine claiming that both of them are BloodKnights who use war as a medium to satisfy their bloodlust since it is the only means they can fight and been seen as heroes instead of monsters. Rhodey disagrees arguing he does what he does to try and prevent wars compared to Ares who willingly starts them for fun.
* ''ComicBook/TransformersRobotsInDisguise'': Prowl was fused with the Constructicons, and they all got a look at each others minds. He calls them some of the most vile Decepticons ever, they in turn really like him because of all of his devious ideas. Prowl isn't happy that they keep following him around and [[YourApprovalFillsMeWithShame complimenting him]].
* ''ComicBook/TransformersDarkCybertron'': The Autobots and Decepticons have an EnemyMine situation to stop Shockwave and all of his machinations. When there's a lull in the fighting, the bots and cons proceed to go to a bar get drunk and sing old Cybertronian songs.
* The sides of the war in ''ComicBook/{{Arrowsmith}}''. Underlined with a DescriptionCut.
--> '''Captain Foxe:''' That's the difference between us and them -- even if our wizards had the sort of minds that could even think of such things, we would never, never use them. \\
''Cut to magister Boisrond testing the new weapons of mass destruction.''
