Jack Bauer shouldn't be able to walk by the halfway point of a typical season, and that's before you take sleep deprivation into account. By the time a season is over it's not uncommon to have seen him bleed from the mouth, forehead or arm at least once. Here's some of the worst ones. If this doesn't prove how much of a badass Bauer is, then nothing will:
Day 1: Grazing bullet wound to the gut. Overall it's one of the more minor ones on this list. Also had to contend with Nina after this.
Day 2: Survives a plane crash in the first half of the season. Is later captured and tortured nearly to death.
Day 6: More torture (at the start of the season no less). Later on Jack gets cracked ribs.
Day 7: Infected by a biological weapon. Quite possibly the worst one.
Day 8: Superficial knife wound early in the season. Serious stab wound in the final hours. Didn't seem too bad at first but as Jack walks away from the wall he's leaning on there is a very serious bloodstain on the wall. Shot in the final episode and even survives a serious car wreck before the end.
The Adventures of Brisco County, Jr.: The pilot episode features a comic relief Mook named Pete, who ends up getting shot. The producers liked the actor's performance so much that they brought him back, explaining that he had recovered after getting hit in the gut. Then they decided to just go with it and had him survive the likes of Chinese throwing star and pitchfork attacks.
A very common trope. Justified for Buffy, Faith, and the assorted vampires and demons and other beasties, who are supernaturally tough and can take insane amounts of punishment without blinking. However, Xander, Willow, and especially Giles should be quadriplegics several times over by now.
Roden survives getting stabbed in the back with a pair of garden scissors.
In the two parter "Lo-Fi"/"Mayhem", Aaron Hotchner gets blown up and is still together enough to attempt first aid on a severely wounded colleague and help get her to hospital even though no first responders will help him for fear of being the target of a second wave of attacks; he collapses briefly at the hospital, but is soon heard from fretfully demanding his clothes, after which he goes with the rest of his team to hunt down the bombers, even though he's still half-deaf from the first blast. The Reaper should have done a little research: if a bomb couldn't slow Hotch down for long, severe exhaustion plus a dozen or so stab wounds were never going to do more than keep him in bed for a few days...
This is made even more impressive by the fact that the series' tough guy, Derek Morgan, gets knocked unconscious twice, by The Reaper in "Omnivore" and by Billy Flynn in "Our Darkest Hour". If Hotch can do better than Morgan...
Morgan recovers later in the series. In "Supply and Demand", he gets tackled by a much bigger security guard and despite taking several big blows (and getting some in himself), after getting rescued by teammate David Rossi, Morgan shakes off the attack like nothing happened.
Deadliest Catch: A Real Life example with Freddy Maughtai, deckhand aboard the Wizard. It's opilio crab season—February on the Bering Sea, when the water is literally freezing cold. The crew were having trouble tying line onto a dead walrus. Freddy jumps into the water after stripping to his skivvies. Most people would go hypothermic within moments of doing that. He was in the water for over a full minute, and he wasn't even shivering when he was pulled out. That is a level of toughness you don't see even among most crabbers, and a remarkable tolerance for cold that you certainly wouldn't expect from someone who hails from the South Pacific.
The companions, almost all of whom are human, are put through the physical and emotional wringer nearly every single time they step out of the TARDIS, yet are perfectly fine the moment they step back in. The Doctor himself partially justifies this by being a Sufficiently Advanced Alien, but considering the things he's been through, it's amazing he can still walk.
The End of Time. Never mind the fatal radiation poisoning, the fall from the Vinvocci ship should have had him ready for his next regeneration.
Jack Harkness, who keeps dying and getting better. Whatever keeps him tethered to life is Made of Iron.
Dollhouse: Played somewhat inconsistently. Sometimes, people go down really fast. Other times, well, watch the fight between Boyd and Ballard (particularly the part where one bashes the other's head with a rock).
The series has an entire race of Made of Iron's, the Scarrans. To drop just one takes a whole lot of firepower: God help you if you run into more than one of them.
Ditto Scorpius: not only is he half-Scarran, but he also wears body armour for anything his body can't deal with. Add to that his own impressive willpower, and he's damn near unstoppable. And even if it looks like you've somehow managed to kill him, well, chances are he planned ahead enough to be back again in a fortnight. Although there is his coolant system, which has been attacked by both Crichton (who sabotaged it) and Emperor Staleek (who tore the whole mechanism out of Scorpy's skull with his bare hands). To their mutual annoyance, Scorpius survived both.
Fringe: If there's anything that will take Olivia Dunham down for more than about half an episode, some very determined people haven't found it yet. Although when she was in a car accident caused by William Bell pulling her into the Alternate Universe, she did take a few episodes to recover fully, even needing to walk with a cane for awhile.
Kouga Saejima/GARO The Golden Knight takes this to HSQ levels, he's been thrown off buildings, shot at point blank range, SLASHED IN THE CHEST WITH A SWORD and IMPALED TWICE IN THE SAME SHOULDER, it's safe to say that this man is the personification of this trope.
This trope is probably part of a Makai Knight's training.
Grimm: The protagonist Nick Burkhart regularly takes blows from incredible opponents, and wrestle's with creatures that posses superhuman strength, notable demonstrations of his durability include being pulled out through his cars window and thrown onto the pavement, having a toaster smashed round his head by a super strong part jackal creature and receiving a beating from a giant ogre and only getting a few bruised rips. Justified Trope in the fact he is a Grimm, a superhuman warrior.
Home Improvement: A humorous example would be Tim Taylor, who despite his tendency for stupidity and Lampshade Hanging about being notorious at the local hospital, never receives scars or injuries of any severity.
House: To provide just one example, after the events of "House's Head"/"Wilson's Heart", House should either be dead or suffering serious brain damage by now.
iCarly: Freddie endures what sounds like a brutal beating from Sam in the episode "iMeet Fred", being hit hard enough with a tennis racket to cause it to break. A blow of such severity to the head (say from Sam wanting to knock some sense into him) would likely result in loss of consciousness, a concussion, and severe bleeding from cranial lacerations. Striking any part of the body that severely would be intensely painful and would result in definite physical trauma, and likely broken bones. However, at the end of this, Freddy walks out looking somewhat mussed and scared, a little bruised but no worse for wear. Moments later Sam pushes him out of a tree house, and yet he is still able to actively take part in making Fred videos afterward.
Kamen Rider: These shows are just as bad. Just ask Kamen Rider Ichigo, Nigo and Riderman, who survived nuclear explosions to the face and come back just in time to aid other Riders! Then there's Kamen Rider Fourze, who, in his cameo in a Kamen Rider OOO movie, made his arrival by crash landing from low orbitHEAD-FIRST, and just hopped up from the ground, dusted himself off and went to aid OOO. All he got out of that was a mild headache.
Merlin: There's a debate in the fandom whether or not Merlin is immortal like his mythological counterpart. Thus far in the show, he has taken a fireball to the chest and got up unscathed, gotten hit by a freezing cold spirit that had killed all previous victims and disabled his magic (although he was dying that time and had to be saved by brook spirits)note And even that's debateable, as the brook spirits themselves said that he had great power, which could mean that he would have eventually survived, and had a mace slice across his chest that most likely left a huge, open hole, and he still had enough energy to carry on a conversation with few winces.
NCIS: Los Angeles: Averted Trope in the episode "Personal", Marty Deeks is shot at the beginning of the ep and while he does manage to struggle out of his hospital bed near the end, he's bleeding through his bandages, and collapses once the danger is past.
Once Upon a Time: Red Riding Hood, of all people, comes off as this in her Day in the Limelight episode: her grandmother shoots her with a crossbow while Red is in wolf form, and it takes her down long enough for Granny and Snow to put the red cloak that keeps her human over her. Once she's back in human form, she isn't injured at all, even though she was clearly shot.
Commander Doggie "Boss" Kruger in Tokusou Sentai Dekaranger was a bit inconsistent with this trope: During his first on-screen brush with death, he was shot in the chest and survived with nary a scratch (though he was wearing a Bullet Proof Vest); much later, he attempts to stop an old friend of his gone mad and was hurt enough (even through his Dekamaster armor) to need a few days in bandaged hospital care. During the season finale, however, he's not only beaten and slashed with swords repeatedly (without his Dekamaster armor on), but slammed through at least three walls, one of which he was stuck in for a half-second, but this only rendered him unconscious for a little while with little more than battle fatigue and a few somewhat minor scrapes.
His counterpart in Power Rangers SPD was even tougher: the finale had him and his wife drop several stories from an exploding alien Humongous Mecha, and still have enough fight left in him for one final match with the series' Disc One Final Boss. And his first onscreen brush with death was in an episode that was nearly a Shot for Shot Remake of the original... minus the part where there was a vest. The old dog is just that tough.
Doggie: *waking up just as they're discussing how bad his wounds are* "Who are you calling an old dog?"
While all series are guilty of this to some extent, Time Force is particularly egregious with this. The red ranger repeatedly fell from heights that should have shattered him. One episode in particular stands out: the red ranger was recruited to be a stuntman for a scene where not only he's cut with real swords, but he falls at least five stories onto concrete after the cushion is taken out from under him. He's "lucky to be in one piece" indeed.
The Quantum Ranger also showed this in one scene where he's shot in the arm as he falls several stories off a bridge into a river. Plus there is a climactic scene where he and the red ranger swing out through a window, fall several stories out of clocktower, and manage to morph and land on their air speeders with nary a scratch. In real life, these two guys should have been dead several times over, but all is forgiven because of the Rule of Cool (and that last stunt in particular was pretty damn cool).
Ninja Storm'sGrand Finale may be the worst offender: The Big Bad has absorbed all of the Rangers' powers, so they, as civilians, must fight a much, much, much stronger version of their foe. Somehow, being blasted full-on is shrugged off, less thanOnly a Flesh Wound.
Heck, there are plenty of times when unmorphed Rangers take abuse they shouldn't be able to withstand. For example, in episode 13 of Wild Force, Taylor gets distracted by Zen-Aku's hold on Princess Shayla, leaving her back unmorphed and unprotected from the motorcycle org. Said org fires two shots at her, which explode very close around her, knocking her to the ground. She's sitting on the ground "injured" for less than five minutes (or until the other Rangers show up), and is then walking around is if she's completely unharmed, only holding her arm in a way one does when they accidentally walk into a door. You're awesome, Taylor, but there's no way you should've healed that quickly.
Revolution: Charlie, in episode 7 where she literally shrugs off being beaten into unconsciousness twice and getting branded, to boot and comes back swinging. Episode 9 tops this by having Charlie Matheson shot in the side of her head and hitting her head on concrete. Even though she has a near death experience, all she has to do is wake up from it, get back on her feet and she is as fit as a fiddle.
Chloe Sullivan once took a Super Strength punch from Clark directly to the face and is completely unscathed.
Lana was once beaten up by Zod and is up and about in no time.
Lois once had her and her car thrown high into the sky then crash down courtesy of a very jealous Maxima. She barely had a scratch on her.
Yes, he spent a few weeks in the hospital, but Jimmy Olsen still looks pretty good for someone who has been mauled in the chest by freaking Doomsday.
Chloe was once knocked down and showered by shattered glass, which doesn't leave a single scratch on her. The odd thing is, Oliver is covered in small cuts in the same scene.
A special mention also goes to Tess, who was voluntarily killed by a defibrillator and then brought back to life with atropine. She wakes up, sits up, looks weak for about five seconds, and then walks out of the room as if she wasn't dead ten seconds earlier.
Slade is probably the very worse case. He took a couple of hits from Hawkman's mace and somehow survives not one, but two huge explosions. The first one took one eye. The second one doesn't seem to even scratch him. Lampshaded on the second occasion - a possible explanation might be that he is under the influence of Darkseid.
Star Trek: The Original Series: In several occasions with Spock, whose Vulcan physiology was used as a kind of armour. For example, in the Season 2 episode "The Apple" he is shot full of poisoned thorns and later struck full on by a bolt of lightning, both of which killed Redshirts instantly. Not justified, as on many other occasions he is shown to be fairly vulnerable.
Supernatural: In "Born Under a Bad Sign", Dean got pistol-whipped, shot in the shoulder (and later had a thumb digging into his bullet wound. Ouch), nearly got beaten to death and was left to drown in icy water. And after all that, he still manages to drive? The boy is super-human!
This show is of course just as bad, if not worse. Unmorphed Rangers and bystanders are often seen simply sent flying by explosions and landing without a scratch, severe cuts heal far faster than they ought without special healing tech, etc.
Special mention goes to Captain Marvelous of Kaizoku Sentai Gokaiger and Rookie Red Ranger Kiryuu Daigo of Zyuden Sentai Kyoryuger. These two Red Rangers show early on just how much they live this trope. To put it in perspective, Marvelous used his own body to intercept an attack that would have hit Joe. This act of Taking the Bullet knocked Marvelous out of his henshin, but he still was able to get in a shot from his Gokai Gun on Warz Gil before he had to be taken off of the battlefield, and in the next episode he was ready for more action even though it was pointed out by the others that he hadn't finished recovering yet. And Daigo takes the level of durability that Marvelous demonstrated in the above example Up to Eleven by Taking the Bullet for Torin without even morphing first, but at best the attack he took only gave him some Clothing Damage. If that's not Made of Iron, this troper doesn't know what is.
Trailer Park Boys: Ricky has been repeatedly shot, often by accident, although always in a non-vital area. The worst damage he usually suffers is to his pride.
Vikings: Bjorn Ragnarsson receives the nicname "Ironsides" because he survived a long battle without a single injury despite always being in the thick of fighting. The nature of the fighting meant that even the most experienced veteran warriors ended up with some injuries but Bjorn did not have a single scratch on him.
The Walking Dead: Rick has feet Made of Iron. He hobbles out of a hospital loading dock down metal mesh work stairs, wanders around a city, and rides a bike (pedals have some pretty big protrusions and ridges for traction) all completely barefoot. Granted, he probably has other things on his mind, but still...ow.
Walker, Texas Ranger: The prototype soldier, a muscle man and enforcer of a supremacist bent on ruling the world by the end of the episode "Warriors." The soldier — whom the supremacist intends to clone thousands of copies of — is genetically enhanced, thanks to a researcher being forced to do so at gunpoint (she had created a quick-heal formula to help the ill and injured). The soldier's invulnerability is clear when Walker and Trivette are unable to so much as even make him flinch during their early encounters ... not even a machine gun full of bullets or Walker's roundhouse kick can beat the soldier. (Eventually, Walker does beat the man-mountain soldier, thanks to some help from the researcher, a flaming torch and a little gasoline.)
