Nigh Invulnerability/Anime and Manga

He is if not Made of Diamond, then at least incredibly durable, being able to block a really freaking huge sword with the just the side of his arm, was somehow manages to, and
 * Ranma One Half
 * Ryoga Hibiki, especially after his Bakusai Tenketsu training. Since he's thrown himself into boulders hundreds of times and gotten hit by subsequent shrapnel just as often, his body is hardened such that most common attacks are utterly useless.
 * The warrior Lime, retainer to the Musk Dynasty's prince, is even sturdier.
 * The Phoenix King Saffron can regenerate instantly from any injury via his own flame. He has only one weakness: being frozen solid. And even then, that merely stops him, but it won't destroy him: after being frozen and shattered into a million pieces, he regenerated as an egg and hatched immediately afterwards, albeit as a toddler.
 * Sanosuke Sagara of Rurouni Kenshin. The trademark of his fighting style is to absorb damage from his opponents. He has taken a ball and chain to the face, and was once thrown through both of the dojo's walls, only to remark that the technique used on him was a rubbish technique. He also took a palm slap that embedded the user's hand into solid stone without even flinching.
 * Hao Asakura of Shaman King is of the resurrection type. By the time the story rolls around, he's already been killed twice. Trouble is, he's an immensely powerful shaman who retains memories and powers gained in his previous lives and, in fact, dying actually amplifies his power further. The entire second half the series is spent trying to find a way around this. In the end, the heroes convince him to abandon his plans to kill all humans, instead of outright killing him again.
 * Zelgadis of The Slayers is a Made of Diamond version, in the context of his universe. Merged with a demon and a stone golem, his entire body is made from living rock. This makes him superstrong and a lot heavier than he looks, but also extremely difficult to hurt due to the fact that all of his "squishy bits", external and internal, are made from organic granite. It takes incredible concussive force to cause anything resembling internal injuries, and bladed weapons are useless (for obvious reasons). In the third season of the anime, he takes a cannonball to the face at point-blank range and is merely knocked out for a few seconds. Even magic isn't that useful against him- at one point, he claims that only something as powerful as the Sword of Light can hurt him, and that turns out to be a Demon Lord from another universe. The only creatures in the series that have been able to truly hurt him are the native Demon Lords and creatures of their power level.
 * Or whenever the writers feel like hurting him.
 * Gourry also seems to display this trait in a fashion similar to The Tick. He gets blasted a lot by Lina Inverse (usually for saying or doing something stupid) with spells that are normally fatal and often finds himself on the receiving end of a lot of punishment, and comes out with little more than some soot on the face. Of course, in this case it's Played for Laughs.
 * All of the homunculi in Fullmetal Alchemist can regenerate; however, certain homunculi have other defenses in addition to this. Greed's Ultimate Shield was Made of Indestructium by using the carbon in his body to cover himself with a layer of material as hard as, and tougher than, diamond. (Ed cleverly got around this by transmuting the carbon into a softer form.)  Ultimate Eye lets him see the outcome of any given situation before it happens, so he is very good at dodging just about anything. This is especially helpful in the manga, where he is the only homunculus who doesn't have regenerative powers. The 2003 anime's Sloth can change herself into liquid, and is an example of intangible.
 * , like the homunculi, has the ability to regenerate any damage, since.
 * For that matter, Al falls under "external repair." He's a soul bound to a suit of armor by an alchemical rune painted on the inside of his neck. Although he's hampered as you'd expect by damage to other body parts, as long as the rune's undamaged, he's still alive, and with a bit of work, can be repaired through alchemy -- although care must be taken not to damage the rune in the process of making the repairs.
 * Out of all of the Homunculi, the very toughest and hardest to kill is probably Sloth. They only manage to temporarily stop him by
 * The Big Bad
 * Many of the villains in Dragon Ball could regenerate. The Namekians' had this ability although it's fairly constrained compared to the following two, as they could only regenerate if their brain was still intact. Cell however, due to his unique genetic make-up recovered from having his entire upper body destroyed, and later literally rebuilty himself From a Single Cell after blowing himself up. Buu (who was also The Blob) is even more extreme. He was blown into a million pieces, and then had each piece vaporized; he regenerated from the vapor. He also came back from a planetary destruction (that he caused). Frieza could survive with most of his body destroyed, although his lack of a renegeration ability meant that he had to make do with cybernetic implants, falling under External Repair. On a side note, pretty much every major fighter was also Made Of Diamond, mostly because they could use their gigantic powers to shrug off damage.
 * This is a fairly common trend in Naruto for villains.
 * Kimimaro had a bloodline that essentially relied on the Made of Diamond route; he could make his bones harder than steel and was able to use them as armor anywhere on, or in, his body. The most damage he suffered from attacks (including his own) was the loss of some skin, which he also seems to be able to rapidly heal. He only ended up dying because of a incurable illness.
 * Kakuzu combined his earth-based Made of Diamond technique with four spare hearts.
 * He can somehow also reattach the limbs of people to give them full functionality, even Deidara who had not shown to have special healing powers himself.
 * His partner, Hidan, was genuinely immortal, and simply needed severed appendages sewn back on. Word of God though, is that malnutrition will eventually kill him.
 * Pain, the Akatsuki leader, has six bodies; unless all six are dead at once, he can just find new ones to replace the ones that die and come back at full strength later, and one of the bodies can restore the others instantly.
 * Itachi & some other Mangekyou Sharingan users can summon
 * Former member Orochimaru could simply 'shed' his damaged body like a snake, forming a new, intact body. Even if a body is suffering permanent damage he can just get a new one.
 * Besides that, he had an impressive ability to regenerate beyond shedding, as well as damage resistance. Sasuke threw several attacks at him that should have killed a regular person in the Forest of Death, but none of them did the job, presumably because Orochimaru isn't exactly human anymore.
 * Tobi can make anything simply phase through his body  However, he's vulnerable when attacking because he can't have different parts of his body be tangible and intangible at the same time.


 * Sasori, who had made himself into a puppet, combined Spare Body Parts with a backup body.
 * Konan can avoid physical damage by turning into paper or she can use a paper clone as a proxy. However, her paper can't unfold very well if it's covered in oil, though it's unknown if this makes her vulnerable to regular attacks or just unable to use her paper for anything. And if she just runs out of chakra, she can't do either.
 * Suigetsu is Made of Air, or rather water (literally), which apparently requires that he drinks a lot. Conversely, having a lot of water makes him more durable, to the point where being a lake let him survived an attack which vaporized several mountains (although it did knock him out).
 * Jugo is both incredibly durable (his skin can become harder than steel, and a hit strong enough to take out a half bowling ball-sized piece of his chest left him out of breath) and can apparently take replacement organs from other people.
 * Naruto himself is no slouch on the not dying front. His Super-Powered Evil Side comes with a Made of Diamond energy shield and enhances his Healing Factor considerably, at level one. By level four his regeneration is such that despite being constantly flayed/burned by his power he takes no lasting harm whatsoever. That is, except for a shortened lifespan.
 * He also counts as Proxy, due to his nearly instinctive habit of using shadow clones.
 * On the other hand, there are some injuries his Healing Factor apparently cannot take care of, at least not while not using the fox's chakra, such as having some of his heart valves sliced apart.
 * Gaara, another Jinchuuriki, has a similar level of invulnerability from sand blocking attacks, such that he can't even hurt himself. It's actually implied that his fight with Rock Lee was the first time he had felt physical pain. We even find out that his father, the Kazekage, had actually been trying to kill him for years without any success, even when he was a kid.
 * He does still have an automatic defense
 * has the power to
 * As highly skilled medical ninja, Kabuto and Tsunade both have extremely potent regeneration abilities.
 * Many characters in Nasuverse have Nigh Invulnerability, though one of the themes of Tsukihime is "death is inescapable". Good thing Shiki's power bypasses most of these entirely...
 * Most True Ancestors can locally reverse time to regenerate their bodies, even if they're completely blown apart. Arcueid was even able to revive after being killed Deader Than Dead by Shiki at the beginning of the story, albeit by rebuilding her body from scratch at the cost of most of her available power.
 * Ciel is unkillable for the duration of Tsukihime. As explained, because Ciel is, and Roa is still alive , the world itself will not let her die to prevent a paradox from occuring. Ciel herself possesses extreme regeneration abilities.
 * One of the antagonists, Nero, has a body composed of pure "chaos", and contained within are 666 beasts. If they are killed outside of his body, the chaos will return to his body and regenerate; he only dies when all 666 lives inside are destroyed at once, making him practically indestructible. Even if you hit him with a force that can destroy continents, he'll still probably have 100 lives or so left.
 * In the sister universe Kara no Kyoukai, Aozaki Toko has a replacement body, which is completely identical to her original in every way. It's even flesh and blood, apparently, and only activates when the original body is killed. Don't bother trying to figure out which is the real one. It's a bit confusing.
 * Even the Mystic Eyes of Death Perception wielded by Tohno Shiki has limitations. ORT, which is already canonically the single strongest being in the Nasuverse, cannot be affected by it due to it having a completely different 'concept' of death than humans and Gaia. (Theoretically Shiki could eventually figure out the concept of a Mercurian death, but it's far more likely that his brain would be reduced to mush first.) Arcueid herself has no lines or points of death under a full moon, and in her Archetype Earth form, even Ryougi Shiki, whose own M Eo DP are even more horribly broken than Tohno Shiki's, cannot find any lines or points.
 * While all the Servants of Fate Stay Night can probably fall under this category to some degree, special mention must be made for Berserker, aka who, thanks to his Noble Phantasm,  not only can't be affected by any non-fatal attack (an attack of at least A-rank, in terms of power, if memory serves), but regenerates until you kill him 12 times. Yes, you read that correctly, he has to be killed 12 times in order for him to truly "die" as a Servant.
 * And it makes him resistant to any attack that manages to kill him, so he has to be killed in twelve different ways in order to finish him off, although he only develops the resistance once he has finished regenerating, so it is possible to finish him off if he is struck multiple times within that window of opportunity.
 * One of Saber's Noble Phantasms is which grants her passive regeneration and prevents aging, and when activated it shifts her into another plane of existence, making her completely immune to all forms of attack. Unfortunately, it was stolen from her while she was alive, so she doesn't get to use it.
 * In One Piece, most Logia-type Devil Fruit users get the "made of air" version, with an appropriate Achilles Heel. For example, Eneru's Rumble-Rumble fruit made him living electricity, which could be countered by the protagonist's non-conductive rubber body.
 * All of them have two weakness they all share though. One is that eating said fruit causes them to lose the ability to swim, forever (a pretty big deal considering the fact that they're all pirates or Marines). The other is that they're still vulnerable to users of Armament Haki, a discipline of Haki that allows users to attack the "substantial body" being protected by the Devil Fruit's abilities.
 * It's explained that the inability to swim is due to a particular mineral in the ocean that has adverse effects on Devil Fruit users. While it does not actually negate their powers (Luffy's neck could still stretch underwater), it makes them utterly weak, so they lack the ability to do anything that requires conscious effort, such as transforming into their element. This didn't stop Eneru from surviving a potentially deadly attack coupled with direct exposure to this mineral, however; after he hit the ground, dead, his electricity-based powers restarted his heartbeat. In fact, Eneru's invulnerability was never overcome completely. He was just finally beaten senseless in the normal fashion and sent to the moon.
 * Luffy himself recently exhibited a Made of Diamond aspect when if he can survive it that long...
 * Not to mention he's actually Made of Rubber too.
 * Two of Whitebeard's officers also qualify. Marco "the phoenix" can turn into flame and reform at will while "Diamond" Hose is literally Made of Diamond.
 * Titular Mai-chan from guro manga Mai-chan's Everyday Life is a maid with the ability to regenerate from any and all damage taken. Her job is to be rented by her owners to "clients", who then use her to carry out their sadistic desires. Of course, this being guro, you get to see all the details, and it doesn't hurt her any less, she just regenerates in time for the next round of painful mutilation.
 * This even goes so far as to mental damage: when and finally released, her mind adjusted by
 * The fact that she's virtually immortal (an omake reveals she could die, but only if every cell in her body was burned to ash) is a mystery, nobody can figure out why. It's also shown that she's the only one in the world like that ; that is until we're introduced to a boy with the same properties. Only difference is he likes the horrible tortures.
 * Alucard from Hellsing has extraordinary regenerative powers, being able to build himself back up from a pool of blood.
 * Alucard's rival/opposite number Father Anderson is only marginally less resilient, having readily shrugged off large-calibur bullets into the brain.
 * Alucard's invulnerability is directly tied to his familiars (undead creatures created from the life stolen from the people whose blood he has drank) of which there are thousands (due to his advanced age and particular bloodlust); while his familiars are contained within himself he possesses their collective life, making him very difficult to permanently injure. When he summons his familiars, he personally becomes more vulnerable, although he can recover from injury by deferring damage to the familiars, at the cost of gradually destroying them.
 * At the end,
 * Phoenix Ikki from Saint Seiya apparently has regenerative AND resurrective powers. Oh, and he apparenlty gets a levelup every time he comes back to boot.
 * Naraku of Inuyasha goes through almost every form of this. He initially is just a Hive Mind of demon parts that could stay alive (if crippled) with only his head left. After getting his first new body, he could selectively destroy and replace the parts to get stronger, and was a Regenerator that survived being ripped into many pieces only healing slower each time, as well as having a barrier that could keep most people out. Then he made a sentient Soul Jar that moved him from Regenerator to being practically Made of Air without ever being effected by the wounds in addition to an even stronger shield that hardly anything could get through. Then he reabsorbs his Soul Jar (who was trying to kill him) to lose the Made of Air quality (going back down to regenerator) in exchange for taking it's henchman's traits of being Made of Diamond (actual diamond and the even harder scales of a giant tortoise yokai).
 * Towards the end of the manga, Sesshoumaru gains his power upgrade and becomes this. When his arm is ripped to shreds, he heals the injuries by sheer fighting willpower alone. Then he's stabbed through the heart. Not only does that not kill him, but the force of the power being released from him not only gives him his power upgrade but even completely regenerates the missing arm he'd had for most of the manga. From that point on, he's all but unkillable and proves it when Naraku tries to have him killed via an army of thousands: Sesshoumaru destroys them with a single swing of his new sword.
 * The three members of the Quirky Miniboss Squad in Madan Senki Ryukendo are fought and apparently die several times over the course of the series, yet always return. Rock Crimson is the most noticeable. Near the end, it's revealed that
 * The spare parts thing is a standard ability for cyborgs from Gunnm/Battle Angel. If the heart/lung systems are still connected to the brain and neither are too'' banged up they can survive almost anything and wait indefinitely for repairs (the lead spending literally centuries in a scrapheap ).
 * If a cyborg has a brainchip, ALL bets are off!.
 * 3X3 Eyes: The near-extinct three-eyed mystical creatures known as Sanjiyan Unkara have the ability to bind the souls of mortals to their own, leaving said mortal with the character "Wu" mystically emprinted on his or her forehead and the ability to regenerate quite literally any degree of damage so long as their master lives.
 * Sadly, this results in a serious case of Immortality Hurts.
 * Rin Asougi from Mnemosyne takes the cake with this, as its literally impossible to kill her permanently, not even by , unless she is devoured by a very specific type of creature, which she has been shown able to handle on her own.
 * Well the are one thing, but then we have the
 * That character is revealed to be so it was easy to do.
 * C.C. from Code Geass, being immortal, literally cannot die. She has survived burnings, tortures, bombings, bullets to the head, not to mention drowning at the bottom of the ocean and being crushed by the massive pressure. The only way to kill her is to.
 * Also, . The latter of whom proves that the above spoilers are not entirely true, by killing the former and becoming immortal. And then finds out that the above spoilers are not true again, and
 * In a way not connected to the above two,  In the end, as above,
 * Virtually all of the Angels in Neon Genesis Evangelion are Nigh Invulnerable in some way. Most are simply Made Of Diamond, but there are variations, such as Made Of Air (Leliel), Hive Mind (Iruel), Regeneration (Sachiel) etc.
 * More specifically, the AT Fields generated by both the Angels and the Evas are more or less invincible, and can only be breached by mind-boggling amounts of power (or another AT Field). But without that protection, both Angels and Evas can (and do) get badly hurt quickly. However, Zeruel was Made of Diamond even underneath its AT Field, if taking the equivalent of a tactical nuke at point blank range unharmed is any indication.
 * Finally, the Evas themselves are tough as nails to fight, and have a whole underground secret base dedicated to their external regeneration should they take too much of a beating. Unit 00, for example, takes that same nuke at the same range, and only loses its arms- though it is unable to act, the fact that it is still standing says a lot about the Evas' toughness. No matter how much damage they take, it seems that they can be brought back to full working order, given time.
 * Viral of Tengen Toppa Gurren Lagann became Nigh Invulnerable after Lord Genome gave him immortality complete with a Healing Factor, although it only sees use once. The is a Made Of Air Energy Being variant, but.
 * Immortals and Lost Souls from Mermaid Saga fit the Regeneration/Resurrection variety, with the only things able to kill them being decapitation or complete destruction of the brain. They also are capable of limb reattachment, which the series often uses for disturbing results (all together now, guys: face replacement!)
 * The Book of Darkness' corrupted self-defense program in Magical Girl Lyrical Nanoha A's had ridiculous levels of regeneration, coming back from petrification and getting blown to bits by three Wave Motion Guns. It took an even bigger Wave Motion Gun that vaporizes a target by distorting time and space to finally destroy its physical body, and even then, it would have still returned had Reinforce not taken drastic measures to get rid of her Rejuvenation Program.
 * took the Made of Diamond route with her Saint's Armor. With it, she can shrug off Nanoha's attacks like they were nothing, despite Nanoha using Blaster Mode. It took five Starlight Breakers fired at the same time, each amped up to even more ridiculous levels by a maxed Blaster Mode, to penetrate her Saint's Armor and destroy the Relic inside her.
 * And she was still conscious afterwards.
 * Reinforce herself  shrugged off seemingly everything thrown at her (they didn't bust out the Arc-en-Ciel then) and was ultimately defeated not by brute force but by
 * Colonel Sanders from Mahou Sensei Negima made himself invulnerable by using an illusion during the tournament. In other words, Made Of Air.
 * Kaede mentions that she knows a few things that could dispell the illusion, though. She just didn't use them because she had no proof that Sanders was a bad guy (for the record, he wasn't).
 * There's also Negi's father Nagi, the most powerful mage alive, who's nigh invulnerable because he's just that awesome.
 * Jack Rakan was named: "The Man Who Cannot Die", "The Immortal Fool", "That Damn Guy Who You Can Stab With Swords All You Like And It Won't Do A Thing, Dammit" for a good reason. A little mention of "This guy is so broken it's not even funny!".
 * Evangeline is also pretty much invincible due to the fact that her vampire powers allow her to regenerate any damage. On at least one occasion, she's been impaled by a chunk of rock about an inch narrower than her torso, and she was more mildly annoyed than anything else. Healing does take some effort, though, so it is presumably limited.
 * Negi in Raiten Taisou transformation has Made of Air variant.
 * This trope is rampant in JoJo's Bizarre Adventure, mostly in the form of regeneration. Dio Brando, his vampire servants, and the Pillar Men who spawned them can regenerate from any amount of damage, and can really only defeated by the sun's power. At the end of Part Two, Cars . Part Five also brings us a notable example in the form of the stand, Notorious B.I.G., which was actually activated by the user's death, and as such could not be killed. It was brainless, but relentless and unstoppable, absorbing any blows and regenerating from any damage. It simply attacked whatever was moving fastest around it, and

Then there is  becomes so broken it could even handwave Gurren Lagann's attempts on it. "No matter what ability, it will not happen". This thing has no weakness and you'd soon want to commit sepukku than let it kill you. Truly a terrifying power if it was only given laser beams.
 * One of the Seven Stars in Shikabane Hime is made of gas, meaning he can't be hurt by swords or bullets. He can also change what gas he's made of, so he can be sedative or explosive if he likes.
 * The Humongous Mecha Mazinkaiser is literally indestructible - it withstands several fights, falling into a volcano and atmospheric reentry (including a crash landing) without a single scratch, at the very least. Eventually the enemy catches on, and devotes their efforts to trying to kill Kouji when he's outside of his machine.
 * Its predecessors -Mazinger Z and Great Mazinger- and Grendizer were also nigh indestructible, but not to the levels of Mazinkaiser. Still, Mazinger-Z whitstood a nuclear blast at point-blank range, and Great Mazinger was even sturdier. However, they ultimately subverted the trope
 * Sabrac, from the second season of Shakugan no Shana, appears to possess incredible regeneration skills, as he takes blow after blow from Wilhelmina (including being crushed by two apartment buildings before being nuked), yet regenerates each time he hits the ground.
 * In Guyver, the main character, with the aid of his suit, has been shown to survive having a chunk of his brain blown off, to completely obliterated save a few traces of brain matter on his suit's control medal.
 * The zoanoid Aptom has equally impressive regeneration powers, and can also transform into a perfect copy of anyone he's absorbed, complete with powers. One memorable fight scene had him transforming into a swarm of living rockets to distract an opponent, then rebuilding his body out of the ones that didn't hit.
 * Bleach, most Shinigami are Made of Iron. Captains take this one step further, however. Their opponents have to be uniquely powerful to even harm a captain, let alone defeat them and none have so far been killed.
 * The evil counterparts of the captains, the Espada are this by hollow standards, especially the top four Espada who require even captain-class shinigami to group together against them or (as in the case of Ichigo versus Ulquiorra) to find a new power upgrade during the fight to win.
 * Aizen fused with the Hogyoku which ensured he could keep regenerating even wounds that should have killed him.
 * In Hell Teacher Nube, Nube, Tamamo, and the schoolgirl Ayumi can all project their astral bodies at will, as well as shape it as they see fit. Nube and Tamamo often use it to pose as elementary schoolkids, while Ayumi simply does it to attend school with her friends... as well as to role-play as a Magical Girl. Since these are purely spiritual projections, they can be twisted, smashed, blown to bits, sliced to ribbons, crushed, and incinerated (They often are, but always for comedic effect.) They just pop right back, no worse for wear.
 * An even more extreme case is with a Buddhist nun who wants revenge upon the mermaid, Hayame. Since she ate mermaid flesh, she is invulnerable to nearly all damage, including blowing half her own head off with grenades, getting burned to a crisp, or getting her torso crushed into a bloody mess. The amount of punishment she goes through (all of which is her own damn fault, since her psychotic methods tend to backfire) would be terrifying and gruesome if it weren't absurd to the point of hilarity.
 * Dark Schneider of Bastard!!!! takes this to ludicrous levels. His primary means of defense seems to be a shield spell called "Dispel Bound", which produces a number of shields to block any attack aimed at him. Each shield can take up to the force of a nuclear blast before breaking. And they can only be targeted one at a time. And they auto-regenerate. And he can repair them manually at positively absurd speeds. And in the unlikely event that you manage to get through that, you have to deal with his durability which allows him to take attacks that can destroy galaxies. And should you somehow manage to pierce these defenses, he possesses obscenely powerful healing abilities (of the sort that makes Wolverine look like a girl scout) and finally, he still can't be killed unless you destroy his body, spirit and soul in three different dimensions at the same time.
 * Akuma Shogun of Kinnikuman uses everything but extreme luck in a single fight. His armor is made from combining the bodies of the Six Devil Knights, and if injured he simply ejects and re-absorbs them to Regenerate. He can change his "Choujin Hardness" to make his body harder or softer as needed. The result is that if caught in a hold, he can become Made of Rubber/The Blob to squirm out of it, or to power up can become literally Hard as Diamond to strengthen himself. It's shown that within his armor is nothing, meaning his body is actually Made of Air so most techniques can't even harm him because there's no body to harm. To top it all off, he's also a god. His ultimate weakness is his head, which controls all of the above. But even then, getting in a blow strong enough to significantly damage it is no small feat.
 * The demons in Chrono Crusade are the Regeneration type, at least the high-power ones. Their ability to heal themselves is so strong that one demon manages to quickly regenerate (with some help from a magical jewel) after being so severely wounded his stomach was sliced open and his intestines were spilling out. They do have some weaknesses (including holy water, grave head injuries, and having their heart removed from their body), but it takes quite a bit to truly kill them.
 * Claymore manages to mix Made of Diamond with Made of Plasticine. Awakened Beings can ignore attacks from people who are capable of slicing solid stone pillars in half, but anything they can't outright ignore goes straight through them.
 * The title Claymores are given a kind of mixed-bag.
 * Offensive styles can 'pull themselves back together', while Defensive styles are supposedly able to regenerate limbs. The characters themselves also seem to be undaunted except when the story says they should be.
 * The tribe of Heroes in Heroic Age fall under the Made of Diamond category of this trope.
 * Up to Eleven. These are creatures that have no problems surviving blows powerful enough to shatter moons.
 * Accelerator in To Aru Majutsu no Index has the power to change the vectors or force or energy of anything he comes in contact to in any direction he pleases, just so long as he can do the computations in his head to figure out what needs to be done. tl;dr: This guy can not only survive a nuke, but the nukes power will be reflected right back at you plus a little bit from the force his body would have on the nuke. How efficient. Naturally, both of these are far from invulnerable to The Hero.
 * Said hero himself possesses a hybrid of several nigh invulnerabilities: Extreme Luck, or lack thereof, he's so unlucky that the world won't let him die, he's shown to be able to regrow limbs that are being absorbed, and he may or may not contain/be God or something equivalent/greater due to being La Persona Superiore a Dio.
 * Correction: Fiamma reached the level of La Persona Superiore a Dio. Touma was stated to have obtained a power that made it pale in comparison (Basically Touma>La Persona Superiore A Dio>God)
 * Apparently the hero's go-to power for most of the series, Imagine Breaker, is in reality . Considering that according to the scientists in Academy City the La Persona Superiore A Dio is greater than God and the "Invisible Thing" is greater than La Persona Superiore A Dio, either there is a divine power greater than God that placed the seal on the "Invisible Thing" in the first place or the scientists have seriously underestimated of the gap between human understanding and the power of God.
 * Free is the regenerative type. He's been stabbed, shot, and encased himself in ice (accidentally), and cut in two And he's still around.
 * Keitaro in Love Hina is a humorous example, as he's effectively invincible despite suffering constant attacks from all the girls, plus Amusing Injuries such as getting punched off of a third floor balcony or getting hit by a car. It's lampshaded on several occasions when other characters encourage him to jump from a car onto a plane about to take off, telling him not to worry because he's invincible. On another occasion, he jumps off of a cliff to save Naru, and tells her afterward that he would probably survive, but she wouldn't have.
 * Yu-Gi-Oh! 5D's pulls out the Earthbound Immortals, dark forms based off of the Nazca lines. All seven of them (Aslla piscu, Chacu Challhua, Ccarayhua, Ccapac Apu, Cusillu, Uru, and Wiraqocha Rasca) have a special effect that renders them immune to attacks, Spells, and Trap Cards, and they can attack the opponent directly. The only way to reliably get rid of one is to destroy the Field Spell Card present on the field. Each one also has a fun special effect, ranging from controlling opposing monsters to nuking the field to cutting the opponent to one Life Point. These were not actually tuned down for the real card game, and they are bastards to try and deal with.
 * Yu Yu Hakusho: Both of the Toguro Brothers are this taken to pretty crazy extremes. Younger Toguro is of the Made of Diamond variety, as even when Yusuke finally gains equal power to him, nothing short of a full power Spirit Gun was able to damage him, and even then he only died from the strain put on his body. Elder Toguro is of the regeneration variety, being able to instantly repair almost any wound to his body, shift his body's physical form to dodge attacks, and shift his organs throughout his body. Even  doesn't kill him, as he is able to slowly regenerate from even that. Younger Toguro also has a bit of the regeneration schtick, as his transformations allow him to regenerate large wounds in his body, as shown against Genkai.
 * Yuki Nagato from Haruhi Suzumiya
 * Shizuo Heiwajima from Durarara is a minor case of the Made of Diamond variety from high-school onward. Shinra hates the prospect of operating on him because he's more likely to break the scalpels than actually cut him open.
 * In the Read or Die series, every single character with the powers of paper is essentially impossible to kill as long as a sliver-sized piece of paper is in their possession. They can make paper that can stop bullets dead, cut steel, completely block any blow, and make clothes out of it which basically means that their clothing is also impossible to penetrate. Bombs and fire also don't do anything, and several different characters can create flying machines (such as a giant paper airplane) to allow for safe travel downwards to the ground from impossible heights. Fire also shows itself to be essentially useless, as it will chip away at the paper (which is more to be said than anything else in the series), but the paper is basically flame-resistant while being used by a Paper Master. The only weakness? Water, but even then all it takes is one piece of dry paper or a dry edge and they're fine for the time being. The characters themselves however when unarmed are typically well trained in some form of martial arts or acrobatics training (especially Anita King from R.O.D. The TV who can backflip, somersault, and single jump to the top of large bookcases around a library like she's been doing it all her life dodging bullets), making them still deadly even when unarmed. The only time the characters are shown as easy human people are during the comedic episodes, any other time they are protrayed as unstoppable single person armies unable to truly be stopped even when in a bad position and often times can beat down an entire building's worth of opponents equipped with everything from guns to lasers without breaking much of a sweat.
 * In Black Lagoon, Roberta fulfils this trope during her first appearance, when she is basically an Expy to The Terminator and the only thing that can stand up to her is Revy and Balalaika's Badass Army after running through enough obstacles to kill the rest of the cast many times over. In the Roberta's Blood Trail OVA she single-handedly tears her way through practically everything in the hunt for the American Grey Fox Unit,
 * Word of God says that anytime the body of Kyubei dies; it can easily regenerate another one instantly from surrounding Mana.
 * Walpurgis Night also counts. Homura hammers it with a ridiculous amount of firepower using conventional weapons, but no visible damage is shown.
 * Chiropteran Queens and their Chevaliers from Blood Plus are capable of quickly healing almost any wound. This includes being impaled through the stomach with a tree trunk, stabbed with many large sharp implements and having arms cut off. If bad turns to worse and they are poisoned by Saya's blood, Chevaliers have the option to amputate themselves and obtain replacement limbs.
 * After Hiroshi in Alive the Final Evolution took the Heart of Akuro he became almost literally Made of Air; actually he was made-of-nothingness, his power was 'void' and that was what he was, despite wreathing smoke-stuff into an image of his old body on a regular basis. His former best friend Taisuke punched through the not-really-there body a couple time before he accepted this, and had to do some serious leveling on his heat/life/existence power in order to stop Hiroshi from destroying the world.
 * And then it was all lost to Easy Amnesia and the Time Skip anyway.
 * Raizel from Noblesse seems just can't be damaged by any external force, period.
 * Captain Bravo from Busou Renkin via his Kagugane ability of Silver Skin that is, at least as seen in the series, completely impenetrable and even immune to the Big Bad's Life Drain.
 * A villainess in Speed Grapher is literally made of diamond, a power apparently supported by her frequently eating diamonds (in one case, by biting off some unfortunate girl's ring finger.) In addition to the damage resistance this implies, it's difficult to focus a camera on her (the protagonist's main way of killing things.)
 * Fairy Tail has one Made of Diamond example in the form of Gajeel (who is ironically Made of Iron in a literal sense) and one Made of Air (or water) variant, Juvia.
 * And then there's Hades, who makes Gajeel look wimpy in comparison.
 * Medaka Box's Kumagawa, who's Minus "All Fiction" makes the laws of causality his bitch. Anything that could potentially hurt him has no lasting effect, including death itself. It doesn't matter if you dropped a building on him, he'd just walk it off. Even after  he still managed to survive being stabbed, shot in the head with an antimateriel rifle, tazed, doused in sulfuric acid, and cut up with rusty gardening tools. And that didn't even keep him down for a day.
 * Sunred from Tentai Senshi Sunred displays Nigh Invulnerability on the few occasions a monster manages to get a hit in at all. He's taken drill attacks that shatter mountains In the Back (it tore his shirt, pushed him into a river, and made him angry), was blasted with a Bardiel-class laser beam point blank by a Do-Anything Robot (singed his clothing and made him angry) and an Oni once smacked him in the head with a cast-iron club (the club got bent, and Sunred lost concentration on a game of pachinko. Which made him really angry).
 * The parasites in, well, Parasyte can harden, heal or move very quickly the part of the body they have infected (generally the head), which means that the only way to kill them is to attack a part they haven't infected (by stabing them in the heart, for example). But then is introduced Gotoh, a being made of several parasites covering the entire body, meaning that in addition to faster-than-the-eye-can-see-Shapeshifter Weapons, he can either block, dodge or take anything you throw at him, including high-powered shotgun ammunition, assault rifles bullets, grenades, a car and having his head cut off.
 * The Tekkamen, including the titular hero, of Tekkaman Blade all qualify for this, as part of the transformation renders them Made of Indestructium. Blade takes a military-grade nuclear warhead to the face, and isn't so much as scratched.
