7	{{Immortality}} isn't exactly a superpower you can easily prove to the skeptic. Sure, you can ''say'' that you're ReallySevenHundredYearsOld, but who's to say that they'll believe you? And, while you may have that HealingFactor, you [[GoodThingYouCanHeal need to be injured for that to work]]. It's not like you can have your arm sliced open on demand just to prove that you--
8
9	Wait a sec, ''you can''.
10
11	Self-Mutilation Demonstration is the favorite method of Immortals for proving to others their powers. The method is simple: grab a sharp object, slash open your arm (or any other body part), and let your HealingFactor kick in and amaze your guest. In other words, you take GoodThingYouCanHeal to its logical extreme, deliberately injuring yourself for the sole purpose of proving you have a HealingFactor. Let's hope you also have the superpower [[FeelNoPain not to feel pain.]]
12
13	Sometimes, the empowered individual will ask someone to just HitMeDammit This is either a stylistic variant of the same thing, or a character is using the method to mock {{Mook}}s by revealing that [[ShootingSuperman this is one thing they have in common with Superman]], particularly to justify hitting them back to much greater effect.
14
15	Not to be confused with SelfHarm.
16
17	Compare MachoMasochism, which is more about harming yourself just to demonstrate how tough you are, without the regeneration powers to back it up. An immortal being might pull off FingerExtinguisher. Contrast ImpostorExposingTest, which may use a similar action to prove that the character ''isn't'' anything special. See also ImmortalLifeIsCheap, which can occasionally be used by other characters to nonchalantly display another's immortality by hurting them severely.

20	!!Examples:
21	[[foldercontrol]]
22
23	[[folder:Anime & Manga]]
24	* This was a OnceAnEpisode trick for Yuta in ''Manga/MermaidSaga''. It even got so common that his girlfriend eventually started predicting when the "I'm [[ReallySevenHundredYearsOld really five hundred years old]]..." speech was about to occur and started inconspicuously searching for the nearest pointy object to use.
25	* Happens occasionally in the ''Literature/{{Baccano}}'' series.
26	** Firo uses his [[PullingThemselvesTogether ability to "bleed in reverse"]] as a ''party trick''. Hey, it's better than card tricks.
27	** Huey does it frequently too, though he tends to use more violent methods like setting himself on fire or ripping open his jugular. It's a good way of testing the witnessing "specimen"'s mental fortitude.
28	** Melvi performs this discreetly to Firo by biting through his lip as he introduces himself.
29	* ''Manga/FullmetalAlchemist'':
30	** Greed proves he has the HealingFactor by asking a flunky to smash his head in with a giant, pointy mallet. It ''almost'' happens again later, but he waves down the flunky (already readying his hammer) because they don't have that kind of time.
31	** Lust also rips open her own chest to show [[ColonelBadass Mustang]] and [[BadassNormal Havoc]] her [[McGuffin Philosopher's Stone]].
32	* ''Manga/{{Phoenix}}'': Masato does this after Phoenix the grants him immortality, first slicing his skin open with a knife, then shooting himself.
33	* In ''Manga/DGrayMan'', there's a scene where Road Kamelot tears her own face off using Allen's anti-Akuma weapon so she can show off her HealingFactor.
34	* In the [[CoolBoat Queen]] [[NastyParty Camillia]] arc of ''Manga/DescendantsOfDarkness,'' Hisoka stabs himself in the hand to prove to Tsubaki that he is indeed a {{Shinigami}}, and to try to get her to believe him when he says that [[DeadlyDoctor Muraki]] is ''not'' [[LightIsNotGood the angelic hero]] [[RapeAsBackstory she thinks he is.]]
35	* Ciel does this in differing ways between the manga and the visual novel of ''VisualNovel/{{Tsukihime}}''. In the manga she stabs herself through her eye to the squicking of Akiha, and in the VN she slits her own throat to the amazement of Shiki.
36	* Kira Sakuya from ''Manga/AngelSanctuary'' repeatedly injures his arm to prove to his [[spoiler: host body's]] father that he is actually [[spoiler: a soul that has taken over his real son's dying body]].
37	* ''Anime/AngelBeats'' right off the bat in a variety. Otonashi asks Angel (Kanade) to prove him he's dead. She stabs him in the heart. He survives! ....Or not. Now he knows he's dead for sure.
38	* In the final fight between Dio and Jotaro in ''Manga/JojosBizarreAdventureStardustCrusaders''. Dio Brando, after [[spoiler:draining Joseph Joestar's blood, finally allowing him to properly connect with Jonathan's body]], decides it'd be fun to demonstrate to Jotaro just how invincible (and insane) he now is by laughing maniacally as he begins to severly scratch the sides of his head to the point that his nails dig in then rip off flesh and ramming his finger through his own skull then drilling it in while he taunts him. With his newfound power, the damage [[HealingFactor heals instantaneously]].
39	* ''Manga/MobileSuitCrossboneGundam'' has Tobia doing this to Sharidon after she attempts to get him to join her Newtype supremacist movement. Tobia responds by [[WouldHitAGirl slugging her to the ground]], then cutting his own arm with a knife and splashing the blood on the ground in front of her before running off. Sharidon gets the message: "The blood is the same; there's no real difference between Newtypes and ordinary humans." It doesn't turn her away from her beliefs, but it does convince her that Tobia is never going to join her.
40	* A version that shows both HealingFactor ''and'' KryptoniteFactor in ''Manga/AssassinationClassroom'': Koro-sensei shoots one of his tentacles with [[AppliedPhlebotinum the anti-sensei BB bullets]] in front of the entire class to show that the bullets really do work and he indeed dodged all the bullets. The tentacle grows back a few seconds later.
41	** In later chapters, he shoots a few of his tentacles to show that his SuperSpeed is reduced with every tentacle lost.
42	[[/folder]]
43
44	[[folder:Comic Books]]
45	* A member of ''ComicBook/YoungbloodImageComics'' once cut off his own arm when asked what powers he had.
46	* In an issue of ''ComicBook/TheSandman1989'', an Indian fakir, seeking an audience with a powerful sultan, impresses the palace guards by severing his own hand at the wrist (a wound which, naturally, doesn't bleed) and then reattaching the hand with no loss of function afterwards. {{Downplayed\|Trope}} in that [[spoiler:although he's immensely powerful, the fakir isn't immortal: he ''does'' possess a fruit which grants immortality to whoever eats it, but he refuses to use the fruit for himself]].
47	* There's a vampire comic by the Finnish artist Petri Hiltunen which starts with the vampire holding a pistol while facing his human guest. The human thinks he's going to get shot, but the vampire actually just wanted to prove to his skeptical visitor that he's a vampire -- he shoots himself in the head, and the wound disappears in a couple of seconds. To clarify, the man assumes that the vampire is just a crazy person, and is trying to intimidate him with a gun into agreeing that he is what he says he is.
48	* ''ComicBook/{{Batman}}'': "Contagion" features a man who ''thinks'' he can do this after walking through a plague zone and being unharmed. Turns out being immune to a disease does not translate into being immune from other harm.
49	* In ''ComicBook/SevenSoldiers: Klarion'', Submissionary Judah smashes his fists against a book with iron pages in order to demonstrate his willingness to spill his own blood for his people.
50	* In ''ComicBook/TheMask'' (the original Dark Horse version), Walter is a MadeOfIron hulking bruiser with a masochistic streak, who regularly hurts himself just for fun or to gross out other people. On one occasion, he takes a switchblade and starts cutting the side of his face casually as his employer tries to tell him what he wants Walter to do, and looks quite startled when his employer snaps and tells him to knock it off. On another occasion, he pounds nails into his hand to form a smiley face, then clenches his palm so the blood runs out around the nails and walks away, smiling to himself. And the poor shopkeeper's assistant who witnesses this faints on the spot.
51	* ''ComicBook/{{Spawn}}'': In one scene, Spawn stabs himself in the chest to show Cogliostro how he can't die, even if he wants to.
52	[[/folder]]
53
54	[[folder:FanWorks]]
55	* ''Fanfic/AllAlone'': Sophia's family is sceptical about her account of what's happened to her, so she opens a pair of scissors and rams the blade through her own hand, demonstrating her lack of both pain response and blood.
56	* ''Fanfic/EbottsWake'': When Frisk tries to tell Toriel that they have magic, they are [[CannotSpitItOut literally unable to say it]]. They resort to demonstrating by biting down on their hand so hard they bleed, then healing the damage with [[HealingHands green magic]].
57	* ''Fanfic/NoPlumbersAllowed'': Danny gives himself a small cut with his pocketknife to demonstrate the healing effect of a mushroom.
58	* Midori in ''Ninja Tail'' demonstrates her HealingFactor abilities by having Deidara blow off her hand with one of his bombs and simply regenerating from it when asked why she was partnered with him.
59	* Similarly in ''Fanfic/SonOfTheSannin'', [[spoiler:Rin Nohara]] was brought BackFromTheDead, gaining Hashirama's Wood Release and many other capacities including regenerative healing. To prove it, she cuts off a finger, which immediately regrows with no trace of injury. [[spoiler:[[ChekhovsGun Sai gets a hold of the finger and brings it back to Danzo]], who uses it to stabilize Hashirama's cells that he had integrated into his own body and let him use Wood Release properly.]]
60	* ''Fanfic/WithThisRing'': Since orange rings can rapidly restore someone to their idealized form, Paul uses this several times.
61	** He cuts off some of his own fingers and regrows them when trying to entice Soranik Natu (who wants to be a doctor) into becoming a Lantern.
62	** He later cuts off an arm and a leg and essentially force-feeds them to a [[ImAHumanitarian Spider Guilder]] Yellow Lantern, just to prove that he's not afraid of the worst she can do.
63	[[/folder]]
64
65	[[folder:Films -- Live-Action]]
66	* ''Film/JennifersBody''. Jennifer burns her own tongue with a cigarette lighter, and slashes herself in front of Needy when she decides to share her 'secret' with her.
67	* ''Film/Terminator2JudgmentDay'' has John Connor order the T-800 to show Dyson he really is a robot. The T-800 peels off the skin and muscle of his arm, only to look at the exposed endoskeleton dispassionately. Dyson is understandably horrified by this, so it takes a few seconds for it to sink in...and then he's horrified for a different reason. His wife, who wouldn't have recognized the significance of the arm, meanwhile was probably wondering what the hell was going on.
68	* Although it's not exactly ''self''-harm, in ''Film/MenInBlack'', K shoots Jeebs in the face mostly to unveil TheMasquerade to J.
69	-->'''Jeebs:''' You insensitive prick! Do you have any idea how much that ''stings''?
70	* In ''Film/TheMedallion'', Creator/JackieChan's character is made immortal by the eponymous artifact, and tries to prove this to his partner by asking said partner to first shoot (the partner refuses, saying there'd be a ton of paperwork if he discharged his weapon) and then stab him. After he refuses to do ''that'', Jackie stabs himself. On seeing he's unharmed, the partner then takes the knife and ''keeps stabbing him'' in awe of the regeneration.
71	* In ''Film/{{Highlander}}'', when Connor [=MacLeod=] decides to reveal his secret to the love interest, he clears up any lingering doubts about his immortality by stabbing himself in the chest with a dagger.
72	* [[Characters/ANightmareOnElmStreetFreddyKrueger Freddy Krueger]] does this a few times in the ''Franchise/ANightmareOnElmStreet'' series, mostly just to horrify his victims. In [[Film/ANightmareOnElmStreet1984 the first film]], he says "Hey, Tina! Watch this!" then lops off two fingers, leering at her as green liquid squirts from the stumps. Later, he answer's Nancy's "What are you?" by slashing his chest, revealing more green ichor and what looks like maggots under his skin. In [[Film/ANightmareOnElmStreetPart2FreddysRevenge the second movie]], he emphasizes his "You've got the body, I've got the brain" line by peeling back the skin on his own skull. In [[Film/FreddysDeadTheFinalNightmare the sixth]], he cuts off his fingers (again) while counting the ways people have tried and failed to put him down for good.
73	* In the first ''Film/{{Wishmaster}}'' movie the Djinn blows his brains out at the heroine's command, from which he automatically recovers, thereby demonstrating two things: he must do whatever she says, and he is not to be gotten rid of that easily. He does concede that it hurt like hell.
74	* In ''Film/{{Species}}'', Sil casually cuts off her finger with cutters and lets it grow back, utterly terrifying a woman she had kidnapped.
75	[[/folder]]
76
77	[[folder:Literature]]
78	* In one ''Literature/{{Animorphs}}'', a recently freed Hork-Bajir is suspected of being controlled by a Yeerk (alien brain parasite). His response is to ram his arm blades into his skull and pull his head apart to show his own Yeerk-free brain. Those observing, Tobias, Ax, Marco, and Jake, are all appropriately horrified and disgusted. Tobias, the narrator of that particular book, points out "it's not like it didn't hurt him, either. I could see the pain on his face." He has a HealingFactor, but it doesn't make it any less awesome.
79	* In the ''Literature/WomenOfTheOtherworld'' novel ''Stolen'', Cassandra is [[ArbitrarySkepticism trying to convince Elena (a werewolf) that vampires are real]], despite standing in broad daylight and wearing perfect makeup -- which she would have needed a reflection to apply. So she takes a ballpoint pen and stabs her own hand. The wound doesn't bleed and heals almost instantly.
80	* In ''Literature/InterviewWithTheVampire'' Louis remembers when learning about his new attributes, he jammed a dagger in his arm, and before he could pull it out, the body had healed itself around the dagger.
81	* In the Popol Vuh (Maya mythology) the hero twins use this power to defeat the evil Lords of Xibalba. Xbalanque cut Hunahpu apart and offered him as a sacrifice, and Hunapu rose from the dead. The Lords demanded that the Hero Twins try it on them. The twins did half of the trick...
82	* In ''Literature/TuckEverlasting'' Tuck, after realizing he's immortal, to test it out he ''shoots himself through the heart''. It passes right through him like water.
83	* In ''Literature/ThiefOfTime'', a yeti invites Lobsang and Lu-Tze to chop off his head in order to demonstrate the yetis' SaveScumming abilities.
84	* Miles Hundredlives from ''Literature/TheAlloyOfLaw'' apparently once shot himself in the head with a shotgun to show off his insane HealingFactor.
85	* The title character of the ''Literature/MediochreQSethSeries'', while technically not ''immortal'' and also susceptible to pain, demonstrates his HealingFactor to some villains in the first book to prove that they will probably not win in a fight and should just back down. He opts to ''blow off his own finger'' and watch it regrow.
86	* In ''Literature/DanilovQuintet'' by Jasper Kent, this trope is inverted, when the protagonist sees a vampire's fingers get cut off and they ''don't'' grow back. (It turns out vampires can, with willpower, stave off regeneration. At at the time, several years before the events of the book, it wasn't known that he was a vampire.) Played straight when in the second book said vampire cuts of the same two fingers and lets them grow back, in order to jog the protagonist's memory. The protagonist's son, who at the time is unaware of the existence of vampires, is understandably freaked out.
87	* Mr. Croup and Mr. Vandemar do this in ''Literature/{{Neverwhere}}'' via a knife to Vandemar's hand.
88	-->''"Oh, Mister Vandemar," [Mr. Croup] said, enjoying the sound of the words, as he enjoyed the sound of all words, "if you cut us, do we not bleed?"\
89	Mr. Vandemar pondered this for a moment, in the dark. Then he said, with perfect accuracy, "No."''
90	* The ghost kids in the ''Literature/{{Goosebumps}}'' book ''Ghost Camp'' do this repeatedly.
91	* Not done to show immortality, but in ''Literature/TheColorOfDistance'' Juna cuts her arm open with a scalpel to show the doctors her healing powers.
92	* In ''Literature/DeadWest'', this is used by Gervas, demonstrating that Niall is out of control. He cuts himself with a piece of a broken teacup, and it almost instantly heals. Inverted with that Gervas himself doesn't have a HealingFactor, but the Porcelain Doctor's PowerIncontinence worsened. Our narrator points out that it still hurt like hell, but he managed to convince Niall to try and rein in his new powers by training on him.
93	* Various Undying do this in the ''Literature/{{Horseclans}}'' books. On one occasion, Mara does it ''to Milo'', after seeing him survive what appeared to be a fatal wound, just to make sure he really is. When that fatal wound heals, she cuts her own wrist to show him that she's Undying too.
94	* ''Literature/EdenGreen'' opens with the title character's best friend punching her hands bloody on rusty sheet metal to demonstrate her new [[HealingFactor healing factor]].
95	* Inverted in ''Literature/{{Citadel}}''. Jason Grim's power is to [[LifeDrain drain the life]] from living things; each life makes him stronger, and can be [[HealingFactor expended to instantly heal his wounds]]. He goes into one class combat tournament hopped up on nearly a million fruit-fly lives, making him basically unstoppable. The tournament ends with him pitted against his friend Jenny Awesome, whose power doesn't work on him. Before the fight starts, he pulls out a lighter and holds his finger in the flame until his regeneration consumes all the fly lives, then shows her his blistered finger to prove that he's fighting her fairly with neither of them powered up.
96	* Eli in ''Literature/{{Vicious}}'' tests out his newfound [[HealingFactor healing abilities]] by repeatedly slitting his wrists, though he does this to satisfy his own curiosity rather than to prove a point to anyone else.
97	* ''Literature/TheCavesOfSteel''. Elijah Baley accuses his [[AndroidsAndDetectives android partner]] R. Daneel Olivaw of being a human who is only pretending to be a robot. After patiently listening to Elijah [[TheSummation spell out the evidence of why he's human]], Daneel deactivates the magnetic seal on his arm, causing the artificial flesh to fall off and reveal the machinery underneath. Elijah promptly goes into shock.
98	** In the sequel ''Literature/TheNakedSun'', Elijah orders Daneel to show the metal under his skin to prove to some other robots that Daneel is not human, so that the other robots will obey him and not Daneel. This enables him to escape Daneel's attempt to [[ThreeLawsCompliant stop him from risking his safety]].
99	* ''Literature/TheDaevabadTrilogy'': HalfBreedDiscrimination against ''shafit'' teaches that a Nahid who [[HealingHands magically heals one]] would [[DePower lose their powers]]. After an anti-''shafit'' pogrom, Nahri heals dozens on a busy street, then furiously slashes her arm open and heals the wound in full view of the public -- and the king who had abetted the violence.
100	* In ''Literature/ShadowOfTheConqueror,'' Daylen [[{{Fingore}} smashes one of his own fingers]] to [[HealingFactor demonstrate]] to the authorities that he has genuine Lifebinding powers.
101	* In the ''[[Literature/TheTwilightSaga Twilight]]'' sequel ''Literature/NewMoon'', Jacob offers to show Bella his new power to heal that he got as part of being a werwolf. Bella, being AfraidOfBlood vehemently asks him not to.
102	* In ''Literature/HarrowTheNinth'', Ianthe impales her hand to demonstrate she possesses the effortless HealingFactor of a lyctor. Then she stabs Harrow's to contrast that with her faulty lyctorhood she doesn't, being reliant on the much more limited method of manually patching herself up with necromancy.
103	* Subverted in ''Literature/APracticalGuideToEvil''. When the Squire asks why veterans who fought the [[NightOfTheLivingMooks Dead King]] would have trouble fighting [[TheEmpire Praesi]], Catherine casually asks Staff Tribune Aisha (a Praesi highborn) to stick her hand in a candle flame. She does so... as a demonstration of her bloodline talent that makes her ImmuneToFire.

106	[[folder:Live-Action TV]]
107	* In ''Series/TheFortyFourHundred'', Kevin Burkhoff stabs himself in the hand (which heals) to prove that he has created a [[SuperSerum serum that can give people abilities]].
108	-->'''Diana:''' (''astonished'') You've successfully manifested a 4400 ability.\
109	'''Burkhoff:''' It's getting there. It doesn't always work.\
110	'''Diana:''' ...you just stabbed yourself in the hand.\
111	'''Burkhoff:''' Yeah. I was a little worried about that.
112	* On the pilot episode of ''Series/AmericanHorrorStoryCoven'', Queenie shows off her human VoodooDoll abilities (she can injure herself and cause it to appear on other people without harming her) by stabbing herself with a fork in order to injure Madison.
113	* In ''Series/BabylonFive'', Narn who swear a blood oath against someone customarily send the target of their wrath a video of them making the oath and then slicing themselves on the head.
114	* In ''Series/BloodTies2007'', Henry demonstrates his vampiric nature to Vicki by shoving a knife through his hand.
115	* In ''Series/BuffyTheVampireSlayer'', when [[spoiler:the mayor]] becomes invulnerable in human form, he has a demon-slaying knight slice his head from the top to his neck. The two side reattach almost immediately. He later catches a letter-opener hurled at him by Angel with his palm, leading to this exchange:
116	-->'''Angel:''' Can't be killed, but you don't like ''germs?''\
117	'''Wilkins:''' [[IronicFear Uck, eew, awful things]], unsanitary.
118	* ''Series/BurnNotice'' frequently reminded viewers that while ''physical'' torture [[TortureIsIneffective simply doesn't work]], mind games (while risky), can work wonders. One of their interrogations involved Sam convincing the guy he was talking to that Sam was a crazy sadist by having Sam pretend to get all worked up about how he was going to use the giant knife in his hand on the guy being interrogated, and then "crazy" Sam sliced open his own finger and starting dripping the blood all over the guy's face while continuing to babble on. As you can probably imagine, this ''completely'' freaked the guy out.
119	-->'''Michael:''' [narrating] There's a saying in interrogation: "Violence perceived is violence achieved." You don't want someone screaming. You want him asking questions, asking "What is he doing with that knife?" Asking, "If he'll do that to himself, what will he do to ''me?''" Mostly you want him asking, "How do I make this stop?"
120	* An interesting variation is shown in the ''Series/Charmed1998'' episode "[[Recap/CharmedS5E8AWitchInTime A Witch in Time]]". Piper goes a little back in time and is trying to recruit her past self to help her. To prove that she's who she's saying, and not some doppelganger demon, she pinches Past Piper really hard and then shows the bruise that appears on herself.
121	* ''Series/TheCollector'': One of the Devil's [[DealWithTheDevil clients]] doesn't remember or believe that she made a deal when the deadline approaches, so Morgan convinced her by cutting himself, showing his [[IncendiaryExponent hellfire-powered]] healing.
122	* ''Series/DeadLikeMe'': Daisy the {{Psychopomp}} stabs herself through the hand in front of a priest who's suffering a CrisisOfFaith, then shows him the wound [[HealingFactor instantly healing]] as proof of the supernatural. [[spoiler:Her attempt to restore his faith [[GoneHorriblyRight Goes Horribly Right]].]]
123	* In Season 6 of ''Series/{{Dexter}}'', [[spoiler:this was how Travis proved to Professor Gellar that the two of them were chosen by God to bring about the apocalypse by recreating scenes from the Book of Revelations. Travis stabbed Gellar with a holy sword, and Gellar's skepticism vanished as he watched his own wound heal miraculously... or at least that's how Travis saw it. Gellar actually died from the stab, as you'd expect, and the "Gellar" that has been calling the shots throughout much of the season is actually Travis's hallucination.]]
124	* In ''Series/{{Eureka}}'', recently-fired scientist Carl Carlson sticks a knife through his hand to prove to his old boss that he has, in fact, finally created a process for [[HealingFactor spontaneous cellular regeneration]].
125	* Inverted in ''Series/FirstWave'', when Foster is captured by people claiming to be government agents who know the truth about the Gua. To prove he is really human, the agent in charge lets Foster stab him in the hand, as aliens have a HealingFactor. The hand doesn't heal, convincing Foster. Later, it is revealed that all this was an elaborate alien ploy. In fact, it was difficult for them to create an arm that ''wouldn't'' heal.
126	* In ''Series/TheGates'', a werewolf slices his arm to reassure his succubus girlfriend that she doesn't need to worry about accidentally hurting him.
127	* ''Series/{{Heroes}}'':
128	** Claire has been known to do this quite a few times. To prove to herself that she really can heal, Claire cuts off her own toe and watches her foot grow a new one to replace it. It was more to test how well she can heal, not that that makes it any less crazy.
129	** Adam, upon finding out about his HealingFactor, starts to mutilate himself just to watch his body heal within seconds.
130	* ''Series/{{Highlander}}: The Series'':
131	** An episode has Duncan doing this to an Immortal that has lost his memory.
132	** In another episode it's shown in flashback how he convinced Tessa of his immortality. [[spoiler:He shot himself.]]
133	** Methos does it in another episode, cutting open his palm to demonstrate his immortality to a Watcher he knew.
134	* This is [[Creator/JimCarrey Fire Marshall Bill Burns]]' whole shtick whenever he appears on ''Series/InLivingColor'', complementing the people present on whatever they're doing, only to move right into InsaneTrollLogic speculation on a potential safety hazard, before subjecting himself to such hazard.
135	* ''Series/InterviewWithTheVampire2022'': In [[Recap/InterviewWithTheVampire2022S1E1InThroesOfIncreasingWonder the second scene of the series]], Louis de Pointe du Lac exposes his arm to the bright Dubai sunshine, [[WeakenedByTheLight which immediately scorches his skin]], to remind Daniel Molloy (whom he hasn't seen in 49 years) that he's a bona fide vampire.
136	* ''Series/IZombie'': When protagonist Liv finally confronts [[spoiler:her cop partner Clive]] and reveals to him zombies exists, he is understandably skeptical about it. Being unable to convince him without proof, she demonstrates her zombie nature by stabbing herself with a kitchen knife, which triggers her GameFace and allows her to [[HealingFactor heal the injury]].
137	* A variation in ''Series/{{Jekyll}}''. During his EstablishingCharacterMoment, an unfortunate teenager is [[MuggingTheMonster threatening Mr Hyde with a knife]], and saying he'll hurt him if he comes any closer. Hyde says "Ya think!?" and slowly stubs out his cigarette on his own palm. This is not to demonstrate healing abilities ([[spoiler: Hyde doesn't yet realize the full extent of his powers]]), and is simply to show how un-intimidated he is, but it is still a demonstration involving self-mutilation.
138	* Inverted in an episode of ''Series/LoisAndClark''. After Superman tries to stop a world-ending asteroid by slamming into it, he succeeds, but the blast sends him crashing down, resulting in LaserGuidedAmnesia. As he's slowly recovering, his parents are shocked to find out that he doesn't know that ''he'' is Superman. Naturally, Clark is a bit scared when his father picks up a baseball bat and prepares to hit him, while claiming that it's going to hurt him more than Clark. Naturally, the bat breaks into splinters, convincing the amnesiac Clark.
139	* On an AlternateUniverse episode of ''Series/{{Misfits}}'', [[spoiler: Nathan]] proves to the world that he is immortal by shooting himself in the head and resurrecting on live TV.
140	* ''Series/MyHero2000'' has George shoving a wooden spoon through his ears at one point to show Janet's parents that he's (to quote him) "completely impervious to pain and injury". A second later, [[SurprisinglyRealisticOutcome he realizes they've fainted]].
141	* A variation in an episode of ''Series/PainkillerJane''. The team is hunting a [[DifferentlyPoweredIndividual Neuro]], who is capable of generating illusions in other people's minds, which he uses to kill them. As part of a ploy to stop him, the team pretends to hit him with something that they claim reverses his powers on himself. To demonstrate that he's in a nightmare, Jane shoots her own hand and then shows it to him, as the gaping wound [[HealingFactor rapidly closes]]. The Neuro is convinced, although Jane has to really keep from wincing from the pain.
142	* Played with in an episode of ''Series/{{Smallville}}'' where Clark demonstrates his NighInvulnerability by taking a pistol and firing it several times into his hand. He then drops the expended rounds and shows the other guy his sooty but otherwise completely unharmed hand.
143	* ''Series/Titans2018''. In "Asylum", Dr. Adamson cuts his own throat to reveal Rachel's healing powers to her. This backfires later when her SuperpoweredEvilSide takes the healing back, causing him to bleed out.
144	[[/folder]]
145
146	[[folder:Podcasts]]
147	* In ''Podcast/TheMagnusArchives'' episode "Cheating Death", the statement giver says he can prove that the folktale he told about ChessWithDeath and [[WhoWantsToLiveForever immortality]] is relevant to himself. John mentions the transcript has a huge bloodstain on it after this, and Institute rumors mention someone self-harming while giving a statement.
148	[[/folder]]
149

151	* The Nameless One in ''VideoGame/PlanescapeTorment'' does this rather often. You can even do it to convince someone not to commit suicide. Or you can have him break his neck just to scare people. You can also make good money by letting a jaded SenseFreak experience a sensation of consequence-free murder. [[spoiler:And then, later on, you discover that every time you did that during the game and died, you essentially killed an innocent consequence-free. YouBastard.]]
152	* Albedo from ''VideoGame/{{Xenosaga}}'' on at least two occasions shows off his immortality through self-decapitation. The first time, he's not aware that his brothers can't do it, so their shocked reactions convince Albedo that he's a monster.
153	* A variation of this is stated to have happened to [[BigBad Lord Recluse]] in ''VideoGame/CityOfHeroes''. Though not to prove it to others, but rather to himself. No one ever exactly gave him a manual on what becoming a demi-god fully entailed, so he proceeds to burn, cut, bash and crush himself in various ways, with medical care standing by just in case, to see just how immortal he actually is. Says he had been meaning to test if he could survive a bullet to the head but never was willing to go through with it. He did however find out several times over that ImmortalityHurts!
154	* In ''VideoGame/ResidentEvil7Biohazard'', Jack Baker demonstrates how much of a threat he is by grabbing Ethan's newly acquired Glock and then shooting himself in the head, blowing off half of his skull, just so he can later show off his head knitting itself together later on. In the ''Daughters'' DLC, he also stabs himself in the chest to reveal this HealingFactor.
155	* Happens in ''VideoGame/GhostTrick'' when [[spoiler:the Manipulator]] slams their hand on a burning stove while arguing with Inspector Cabanela, and holds it there for several seconds. [[spoiler:Sissel and Cabanela both note how he didn't even react to the pain.]]

159	* A variation of this trope is used in ''VisualNovel/{{Ever17}}''. [[spoiler:In the Jellyfish Gondola, Tsugumi shows that she has a disease that makes her immortal by killing her pet hamster Chami, which is also infected by the disease. After seeing Chami's shocking sudden death, Takeshi sees an even more shocking sight as the hamster just regenerates so quickly that it looks like he never died after only a minute.]]
160	* Ciel in ''{{VisualNovel/Tsukihime}}'' does this to prove her Immortality to Shiki, slitting her own throat in front of him.

163	[[folder:Web Animation]]
164	* ''{{WebAnimation/RWBY}}'' has [[spoiler:[[BigBad Salem]] - BarredFromTheAfterlife through CompleteImmortality -]] set out to demonstrate her power by traveling the land, challenging the strongest warriors to cut her down and walking away unscathed. [[spoiler:She uses the demonstrations, together with the false claim that she ''stole'' immortality from the gods, to entice the kingdoms of humanity into joining her [[RageAgainstTheHeavens rebellion against the gods.]]]]

167	[[folder:Web Comics]]
168	* Jurinjo of ''Webcomic/EmergencyExit'' makes a large cut in his arm to prove his healing powers to Jason so that he can [[spoiler:fix Karl's face.]] He still feels the pain though.
169	* Jin of ''Webcomic/WapsiSquare'' uses a variation to show that she is indestructible [[http://wapsisquare.com/comic/screeeee/ here.]]
170	* Steve Weatherby in ''Webcomic/CaptainStupendous'' does this by [[http://www.captainexcelsior.com/?id=51 stabbing himself in the throat.]]
171	* Retroactively occurs in ''Webcomic/{{Homestuck}}''. [[spoiler: [[MonsterClown Gamzee]], at one point, parries [[CatGirl Nepeta]]'s claw attack and decides to scrape it against his face. Later, we learnt that Gamzee is functionally immortal, not because he reached [[PhysicalGod God Tier]] as was initially believed, but because of [[ItMakesSenseInContext literal]] JokerImmunity.]]
172	* ''Webcomic/DragonBallMultiverse'': Done by Cell and Gast Carcolh in one of the minicomics.
173	* In Lee's first appearance in ''Webcomic/{{SSDD}}'' he stabs himself with a fork to demonstrate what their new implants are capable of to Julian and Tessa.

177	* Kenny ''tries'' this in ''WesternAnimation/SouthPark'' by shooting himself in the head in front of a group of his friends, but because of his immortality's built-in WeirdnessCensor, everyone's forgotten about it by the next day.
178	-->'''Kenny:''' This time, try and fucking remember! (''blows his own brains out'')\
179	'''Stan:''' Kenny, no!
180	* In ''WesternAnimation/StarVsTheForcesOfEvil'', a young Queen Moon confronts BigBad Toffee and his army of lizards. To show her that they are indestructible, one lizard bites off another's arm, which then regenerates. The second lizard then uses his new arm to high-five his old arm. The whole was comically unnecessary, as Moon already knew about their healing powers and tried to tell them as much, but to no avail.
181	* In ''WesternAnimation/MightyMax'', the psychotic, NighInvulnerable barbarian Spike has a face impaled with multiple branches due to being kicked off of his feet and landing face first in a pile of firewood. He promptly emerged from the pile [[CombatSadomasochist mocking the idea that this could hurt him]], then grabbed one branch and rammed it up his left nostril until it wedged there to prove his point.
