History Main / DentedIron

* ''RequiemForAHeavyweight''
* ''RockyV''
** Really a theme present in '''all''' ''Rocky'' films.
** ''RockyBalboa'' has Duke run down a laundry list of Rocky's injuries, and why he has to train for pure power.
* ''TheWrestler''

* Evoked in one ''{{Redwall}}'' book with Lord Asheye, a Badger Lord who fought a great deal when he was younger and is now always aching because of his many, many scars.
* Very much a running theme in ''Literature/TheActsOfCaine'' series with Hari/Caine

* Batman whenever they show him in old age (TheDarkKnightReturns, ''WesternAnimation/BatmanBeyond'', KingdomCome, etc)
** This shows up in ''Film/TheDarkKnightRises'', though not as much from aging as from injury and inactivity.
* Lampshaded and averted in ''TheDresdenFiles'', where Harry notes that the amount of punishment he's taken over the years would give him the health problems of a football player. But, as a [[WizardsLiveLonger wizard]] he heals perfectly over time, without scar tissue or the aftereffects of broken bones.
* This is the primary reason the original heroes of ''{{Kinnikuman}}'', especially Kinnikuman himself, had to step aside for the younger generation in ''KinnikumanNisei.''
* This trope is brought up in the third and final arc of ''RurouniKenshin''. In the epilogue that takes place five years later, it's gotten so bad that Kenshin has to give up swordsmanship, despite only being in his [=30s=], because his frame was lighter than what his style was designed for.
* Invoked during the course of the ''{{Blame}}'' manga with the main protagonist, Killy, who endures many physical hardships during his journey. By the final chapters, his otherwise indestructible body is literally falling apart.
* Whenever a PoliceProcedural does an episode involving contact sports, there's a good chance that this trope will arise, probably because someone is covering up the fact that a celebrity player is dented iron and shouldn't be competing at all.

* One heartbreaking real-life versions of this was the case of pro-wrestler Chris Benoit. After his death, studies showed that his brain had significant degradation, and certain proteins that are most commonly found in elderly Alzheimer's patients.
* TheUndertaker is the same way. Scarily so in fact, because he has been wrestling for [[BadassGrandpa nearly 30 years]] and he can still go toe-to-toe with the younger guys. In a great bit of keyfabe exposition, John Cena once described TheUndertaker as the only wrestler who intimidates him.
* You'll notice that when BretHart is in the ring now, he doesn't do any actual wrestling moves. He can't. He's taken so many concussions of such severity that he is medically banned from wrestling, lifting weights, or ''flying in planes''.

* Batman whenever they show him in old age (TheDarkKnightReturns, BatmanBeyond, KingdomCome, etc)

* One heartbreaking real-life versions of this was the case of pro-wrestler Chris Benoit. After his death, studies showed that his brain was comparable to that of an 85-year-old Alzheimer's patient (he was 40 at the time.)

* TheUndertaker is the same way. Scarily so in fact, because he has been wrestling for nearly 30 years and he can still go toe-to-toe with the younger guys. In a great bit of keyfabe exposition, John Cena once described TheUndertaker as the only wrestler who intimidates him.

* TheUndertaker is the same way.

Will result in CrackOhMyBack as the person ages.

* Several of the rules in [UsefulNotes/MixedMartialArts] seem to have the intended effect of mitigating this -- for example, the lack of a standing count in MMA as well as referee stoppages (a referee is to stop a fight where a fighter is incapable of or is not "intelligently defending" himself or herself), as well as mandatory medical suspensions (in North American states where the sport is sanctioned). However, as the sport is so young there's only a few fighters who are anywhere near old enough to show this effect... although some of those from the "Dark Ages" of MMA, such as Gary Goodridge, have shown this trope to a disturbing effect.

* ''{{Rocky}} V''

* Whenever a PoliceProcedural does an episode involving contact sports, there's a good chance that this trope will arise, probably because someone is covering up the fact that a celebrity player is DentedIron and shouldn't be competing at all.

* [[OnePiece Whitebeard]].

* Very much a running theme in the ''ActsOfCaine'' series with Hari/Caine

* This trope is brought up in the third and final arc of ''RurouniKenshin''. In the epilogue that takes place five years later, it's gotten so bad that Kenshin has to give up swordsmanship.

* Whenever a PoliceProcedural does an episode involving contact sports, it's practically guaranteed that this trope will arise, probably because someone is covering up the fact that a celebrity player is DentedIron and shouldn't be competing at all.

* Whenever a PoliceProcedural does an episode involving contact sports, it's practically guaranteed that this trope will arise, probably because someone is covering up the fact that a famous or up-and-coming player is DentedIron and shouldn't be competing at all.

* Whenever a PoliceProcedural does an episode involving contact sports, it's practically guaranteed that this trope will arise, probably because someone is covering up the fact that a pro player is DentedIron and shouldn't be participating at all.

From the description from MadeOfIron

"Punch-drunk boxers are the classic real-life example of what happens to someone who takes repeated pummeling damage in many fights year after year. However, the American National Football League is a better sampling. To survive more than a couple of seasons in the league is a guarantee of a lifetime of painful, lingering damage to battered joints, bones, and connective tissues. That life is also going to be about ten years shorter than that of the average adult American. The heart and body organs build up scar tissue likely to fail when the athlete is in his fifties and sixties. "

This Trope is all about that, when someone MadeOfIron starts showing some wear and tear. Will result in CrackOhMyBack as the person ages.

* In the first ''[[BaldursGate Baldur's Gate]]'', Dynaheir implies that her bodyguard Minsc's [[CloudCuckooLander 'unique' view on life]] is the result of taking too many blows to the head over his career as a beserker.
