Logical Weakness / Anime & Manga

Logical Weaknesses in anime and manga.

The following anime and manga have their own pages:

• JoJo's Bizarre Adventure
• My Hero Academia
• One Piece

---

• In Aldnoah.Zero, Trillram pilots a mecha with an energy shield that disintegrates anything that touches it. However, this comes with the disadvantage of blocking out all light, forcing the pilot to rely on remote sensors for guidance. Also, by necessity, there are gaps in the field to allow the mech to walk without falling through the ground, and to be able to receive the feed from his sensor drones. The protagonists exploit these vulnerabilities to great effect.
  • This is how the Earth forces, armed with fairly standard mechs with conventional weaponry manage to keep up with the Martians' more esoteric attacks. For instance, a Rocket Punch is deflected with a pinpoint-accurate shot to deflect its momentum, and a mech armed with plasma swords is dumped in the ocean - the heat causes a tremendous steam explosion that vaporizes the mech instantly.
  • Another excellent use of logic on the part of the Terrans came when a Martian with what amounted to a laser sniper rifle on his mech took the high ground and could bring down anything within hundreds of miles of him. Then, with the help of a spotter on the ground closer to him, a Terran battleship hits him with conventional rounds. He knows exactly where the shot came from and fires back ...and the laser goes over the ship. Lasers are just light when you get right down to it and light travels in a straight line,^note Technically; light can be affected by gravity, which is why you have phenomena such as gravitational lensing; it's just that gravity's effect on light is minuscule compared to its effect on ordinary objects. so the Earthlings just had to fire at him with shells on a ballistic trajectory (arcing, e.g., not in a straight line) from beyond the curvature of the Earth relative to him and he can't hit them back.
• In Angelic Layer, Hikaru is created to be super fast and agile. The problem is that because she is so light, she doesn't have very much strength. She's also unable to fight well on places like an ice field.
• Assassination skills in Assassination Classroom are for getting the drop on a target, not prolonged conflict, making most assassins far less effective at combat than their general competence level would suggest. Infiltration-style assassins like Irina lose most of their effectiveness once their cover is blown.
• The Dragonslayer in Berserk is one of the few non-magic weapons that can kill Apostles (the other few being cannonballs and explosives) with relative ease in short time. It works on the physics of swinging an eight foot tall slab of five hundred pounds of iron into someone until it dies, meaning only someone as absurdly strong as Guts can wield it, and if you don't have the considerable room necessary to swing the damned thing, it becomes a liability rather than an asset. Serpico exploits this twice - once by luring Guts onto a narrow cliff where trying to swing it means he'd fall off from the momentum, and once by attacking him in a room filled with thick stone pillars. (It didn't work the second time - between the weight of the sword and Guts's sheer strength, he simply smashed through the pillars.)
• Black Clover:
  • Asta has several:
    • Asta's biggest weakness is the fact that his abilities rely and take a heavy toll on his body which, aside from being well trained, is still only a human body. When not going into his Black form, he is physically only on the level of a well trained human and is basically just a regular swordsman battling monsters and things that are physically beyond human. Even with his swords Anti-Magic properties and being able to deflect or block magic, it's all still backed up by a human body that can't take lots of punishment before it starts to shut down. This weakness still comes into play with his Black form engaged because his power only enshrouds and reinforces his body but doesn't imbue it with any special properties like a Healing Factor or Nigh-Invulnerability. Basically, think Tony Stark in the Iron Man armor. Sure it makes him way stronger and protects him while giving him extra abilities but it's still just a human being inside.
    • He is entirely reliant on the surface area of his sword for blocking attacks. He can't block the attack if it's too fast for him to bring his sword into the firing path, a fact that Mars uses to beat Asta.
    • The sword Nero shows him when he's on the ropes is smaller and lighter, meaning he can swing it fast enough to parry Mars's attacks. However, since it's smaller he can't hit Mars hard enough to overcome Mars's Recovery Magic.
    • He's useless if his arms are restrained, but he came up with a solution to this by summoning his sword from the book directly to break any magical restraints before beginning to dual-wield.
    • The swords are also limited to how long they are, making it difficult to hit a swift, flying target, especially when Asta's already bleeding and running on empty.
  • Kaiser Granvorka's Vortex Magic relies on mana detection to dissipate enemies' attacks. Fuegoleon is able to slip through it by erasing his magic and using Salamander as a decoy to defeat the elf possessing him.
  • Kyle, a minor member of the Silver Eagles, uses Feather Magic, which naturally doesn't fare too well against Flame Magic.
  • Licht's magic is super-heated and super-intense light, meaning that even though he's extremely powerful, Gauche defeats him in their first encounter by just summoning a giant mirror and reflecting his own light laser back at him.
  • Vetto's monstrous strength comes from a number of enhancement spells casted on himself. Find a way to remove all that from him at once and he's completely helpless, which is what happens when Asta manages to land a solid hit on him with the Demon-Dweller Sword.
  • Lira fights entirely with magical constructs. When Charmy manifests her dwarf heritage, she gains Food Magic, allowing her to consume magic. As a result, she literally eats everything he throws at her.
  • Due to the nature of the Glamour World, while Reve's able to use her magic for her own benefit, it can be used against her as well. This is how Dorothy is summoned to the Glamour World. Because it's just as much Dorothy's dream as it is Reve's, she can't just nullify Dorothy like she could her other dream creations.
  • It's much harder for blood to coagulate underwater. As a result, Vanica's Blood Magic is half as effective in water, making her fight against Lolopechka and Noelle all the more challenging, not that she minds.
  • Svenkin Gatard's Skin Magic adjusts itself to cancel out magic attributes. However, True Magics create the real element itself as opposed to being made of mana. Luck using True Lightning Magic to become a piercing lightning bolt breaks through his defense and defeats him.
• Bleach:
  • Aizen's Zanpakuto can completely control the perceptions of anyone who sees him release it even once. It thus stands to reason that Tousen, a blind captain, who cannot see it, must be recruited to his side, and Ichigo is at an advantage over him, never having seen him release his Zanpakuto. Also, Yamamoto's flame Shikai and Bankai can not be tricked by illusions, so that's why Aizen won't confront him head on. In fact, Yamamoto's plan to counter Aizen was quite literally Kill It with Fire by basically nuking the entire area - it doesn't matter if he can't see Aizen, he knows Aizen is somewhere close, and hence within the blast zone. Without Wonderweiss it might very well have worked.
  • Shinji's Zanpakuto Sakanade is somewhat like Aizen's in that it messes with perception (in his case, he can reverse directions, so up is down, left is right, vice is versa, and so on), and Bambietta takes advantage of the same weakness that Yamamoto did with Aizen- even if she can't find Shinji, she knows he's somewhere in the area, and her Having a Blast power is omnidirectional, so she can just make everything explode and be sure she's hit Shinji somewhere.
  • Izuru Kira's Zanpakuto Wabisuke makes anything struck by it become twice as heavy, with the effect being cumulative- if he hits something three times, it will weigh 8 times as much. However, the extra weight can be used against him, as Matsumoto demonstrates in a filler arc by tricking a reigai duplicate of Kira into hitting a steel rod multiple times and then dropping it on Wabisuke; Reigai!Kira is just as unable to move the rod as Matsumoto would be. It's also completely useless against something that is actually weightless (like Matsumoto's own Zanpakuto Haineko; its shikai form floats in the air) — zero doubled is still zero.
  • Zommari's Amor power allows his eyes to control anything they see. However, 'thing' is singular — he can only take control of one thing per eye (so if he gets someone's left hand, the eye he's using for that can't control any other part of their body, although he can seize control of an entire body if he gets the head of his victim). If there are more threats than he has eyes (like Byakuya's Bankai- he only has 50 eyes, so he can only take control of at most 50 petals out of the millions said Bankai creates), his opponent is free to toast him with the remaining attacks. His ability is also similar to Kido, so it can be blocked using a Kido barrier.
  • Baraggan Luisenbarn is a Walking Wasteland, projecting an aura that rapidly ages everything around him. Since it's always turned on, Baraggan has to constantly protect himself from his own aura. This proves fatal for Baraggan when a rapidly-decomposing object is placed where he cannot protect himself — namely, inside of his body.
  • Byakuya's Shikai and Bankai manifest as a massive number of tiny razor blades that shred his opponent. However, said blades can also cut him so they always stay a certain distance away from him, thus anyone who can close the gap will make Byakuya have to choose between being unable to hit his opponent or risking hitting himself.
  • Kyoraku's Shikai involves playing children's games with his opponent, making them have to follow the rules in order to deal damage. But because they're games, he (and presumably any nearby allies) has to play too, and any opponent who can quickly get the hang of playing life-or-death tag/rock-paper-scissors/Calvinball can use the games against him to hurt him more than they could in regular combat.
  • Moe Shishigawara's Fullbring is probability-based, and usually guarantees that he hits the jackpot with very powerful attacks right away. However, as a result of that, he's increasingly less likely to get a lucky hit as a fight goes on. His first punch against Ikkaku is strong enough to break Hozukimaru, but they get weaker and weaker from there.
  • Rose's Shikai and Bankai are both sound-based, and therefore do not work on deaf people. Mask de Masculine exploits this by breaking his eardrums so he cannot hear the music Rose's bankai makes.
  • Guenael Lee's 'Vanishing Point' power allows him to erase himself from others' memory at will, meaning that potential opponents won't remember why they were fighting. Then he tries it on Yachiru, who's such a Blood Knight that her first instinct to someone she doesn't know appearing out of nowhere is to immediately attack, rendering his defense useless - no matter how often he erases her memory, she'll continue to hit him every time she sees him.
  • Gremmy has the power to make anything he imagines real. Overpowered as all get out? Hell yes, but it has one big problem: it also makes his doubts real. When he fights Kenpachi, he might have been able to defeat him, but Kenpachi's sheer strength in battle made Gremmy fear that he was an unbeatable monster, so Kenpachi promptly became one. He also suffers a Superpower Meltdown when he tries to imagine something happening that he's already imagined to be impossible. In this case, he tried to imagine that he was stronger than Kenpachi. However, since he was already convinced that Kenpachi was invincible, he was essentially trying to imagine himself stronger than infinity, which resulted in him exploding in a rather gory Puff of Logic.
  • Pernida has, among other powers, the ability to absorb powers by consuming their owners. However, in doing so they also absorb any weaknesses or Blessed with Suck tendencies. They are defeated when they try to absorb Nemu, but fail to get her brain. Nemu has a Healing Factor so powerful that without her brain, which serves as a Power Limiter, the regeneration would take over her whole body and turn it into a mass of cancer. Which is exactly what happens to Pernida when they absorb her.
  • Yhwach's power, "The Almighty", allows him to see all possible outcomes of any event he focuses on, and to counter anything he can see. However, the "see" in this is quite literal, as the power functions entirely through his eyes. Thus, he's just as vulnerable as anyone else to Aizen's perfect illusions, which leave him seeing fake possible futures. He can also only see the future, leaving him vulnerable to Tsukishima's ability to change the past.
• Many of the Clow Cards from Cardcaptor Sakura have logical weaknesses. One example: Sakura manages to capture the Watery card by trapping it in an industrial-sized freezer.
• Code Geass R2
  • Suzaku is able to exploit his instinctive fighting style and his Geassed command to "live" to be able to manoeuvre the Lancelot Albion so fast that Bismarck's Geass, that lets him see a few seconds into the future, still cannot provide enough of a head start to counter it.
  • Lelouch can make anyone follow an order of his as long as can look his opponent eye-to-eye (he can use mirrors, but he has to be able to see the actual eye). Mao is able to circumvent this by wearing shades.
  • Mao himself can read the minds of anyone within five hundred meters of him, but without his headphones, he'll buckle under the weight of so many minds.
  • Rolo's Geass allows him to temporarily stop the senses of anyone in an immediate area. But it only applies to senses. Physical phenomena (like bullets already in flight) keep going.
• Darker than Black loves this. The guy with electricity powers needs something that conducts electricity if he wants to attack at a distance, the guy who can freeze stuff needs water (or your arm) within reach to be able to do anything, and in the first episode of the second season, someone with Super-Speed who tries to run in a rainstorm winds up riddled with holes due to elementary physics.
• In Darwin's Game, Kaname has the Fire God's Gavel sigil that lets him create things out of thin air. It sounds amazing, but has its limitations. He cannot create things that are too large — like a car, nor can he create anything too complex that fulfills multiple purposes — like a smartphone. He also can only create objects that he has handled before. If he doesn't know it, he can't create it.
• In Deadman Wonderland, the titular Deadmen each have a unique method of controlling their own blood and turning it into a weapon. But they still also need their blood to carry oxygen through their body, just like a normal human would. Most of them create some sort of melee weapon with their blood and thus can just draw it back into their body when they're done with it. But main protagonist Ganta's power is to fire his blood as bullets. This is one of the most powerful of the "Branches of Sin", but since it doesn't allow him to reuse his blood he'll pass out from the blood loss if he fires too many shots. This is exacerbated by the fact that Ganta is still a child and is fairly scrawny, meaning that he has a lower volume of blood to work with in the first place than the various adult Deadmen.
• Demon Slayer: Kimetsu no Yaiba: Lower One Kizuki, Ennu, can put anyone to sleep the moment he locks eyes with his target. At full power, he can conjure eyes wherever he wants, from any direction he wants. Tanjiro gets hit by this move repeatedly, but Inosuke, who wears a boar head hood that covers his eyes (but can see out of it just fine), is unaffected because Ennu cannot figure out where Inosuke is looking. In an overlap with This Looks Like a Job for Aquaman, Zenitsu happens to be a far more competent fighter when asleep than awake, so Ennu putting Zenitsu to sleep inadvertently made him a fiercer adversary.
• Denjin N: Tadahiro can be only in one place at a time and can only move through the electromagnetic fields. The Sudou hold a meeting in the mountain area and asks everyone to leave their phones, making Tadahiro come up with another way to reach them. Sudou later invite him into a truck with special surface cover, use a faked webcam feed in the laptop, and then lock the laptop in a jar filled with liquid nitrogen rendering him powerless. If Tadahiro didn't come up with a backup plan, the case would have been closed.
• Digimon Data Squad: Unlike the other members of DATS, Marcus Damon needs to physically punch the Monster of the Week to generate a DNA charge so his partner, Agumon, can digivolve. Pit him against an enemy Digimon that's too fast to hit, intangible, or both, and he's screwed.
• Dragon Ball:
  • Guldo can stop time for as long as he holds his breath. Naturally, overusing his power strains his respiratory system until he can only keep time frozen for a couple seconds at best.
  • Android 16 both exploits it and falls victim to it. His fully mechanical nature gives him an edge against Cell that no other member of the cast has, since Cell cannot just absorb him for an easy win. Unfortunately, once Cell evolves into a higher form, 16 can no longer match him in combat, and since he's a robot, he can't train himself to grow stronger like the rest of the cast.
  • Monster Carrot can turn anyone he touches into carrots, but has to actually touch them to do so. Goku gets around it by beating him senseless with the Power Pole.
  • Babidi manages to keep Majin Buu under control by repeatedly threatening to seal him away again. When Buu inevitably turns on him, the very first thing he does is strangle him; after all, Babidi can't recite the incantation to seal Buu away again if he can't speak.
  • Due to their large ears, Namekians have super-hearing. As revealed in Lord Slug, this makes them sensitive to high-pitched noises like whistling. The heroes exploit this when Slug assumes his giant form, making his eardrums the size of trash can lids; the sound incapacitates Slug with pain. Piccolo gets around it by ripping off his own ears so he can't hear it.
  • The Solar Flare technique blinds the opponent with a bright flash of light. It can be countered by simply wearing sunglasses. As shown during the Universe Survival Saga of Dragon Ball Super, it also doesn't work if the opponent is blind.
  • Assimilating others helps Super Buu grow stronger by gaining their powers, abilities, and memories. However, this also forces Buu to absorb their weaknesses, too — both physical and mental. When he absorbed the Grand Supreme Kai in the distant past, Buu's magical power was increased but he also became less evil since the Grand Supreme Kai's gentle nature clashed with the original Buu's unrestrained savagery.^note It's also possible that gaining the Grand Supreme Kai's obesity made him physically weaker, though this is relative since the GSK was only "physically weak" by the standards of Physical Gods. His absorption of Gotenks gave him a major power boost, but that only lasted as long as their fusion limit, at which point he was left with the far weaker Goten and Trunks.
  • As powerful as Majin Buu's Healing Factor is, it's not flawless. If constantly pressured with powerful attacks, his regeneration weakens since it takes more power and focus to heal from them, especially if the attacks are constantly occurring. This is seen in Super Buu's fight with Vegito, and Goku's fight with Kid Buu; Vegito beats Super Buu so brutally that his regeneration actually starts failing and leads him to forget to regrow some parts of his body, while Kid Buu endured so many powerful attacks from Goku that he ended up regenerating his head between his legs. Essentially, to defeat Buu, one has to pressure him to the point he can't regenerate fast enough.
  • Dragon Ball Super gives us Ultra Instinct, a state that can be considered the ultimate expression of Don't Think, Feel, which allows a fighter to dodge pretty much any attack reflexively. The drawback is that it's almost entirely defense-oriented; as Whis explains, a fighter still needs to think when they attack, giving consideration to things like how much force to use and where to strike. Goku finds a sort of work-around while fighting Kefla, letting his body dodge her attacks while he concentrates on charging a Kamehameha, firing it off when he gets right up in her face. On a lighter note, Ultra Instinct is based around avoiding actual danger. If there's an environmental hazard that would just be annoying and/or embarrassing without being harmful, it will be ignored, as Whis inadvertently demonstrates by stepping in poop when showing off Ultra Instinct to Goku and Vegeta.
• In Dragon Quest: The Adventure of Dai, Vearn's "Tenchimatou" is a special stance that allows him to counter an enemy attack, and then using the resulting flow to use three different moves at the same time. The obvious drawback is that Vearn cannot attack while he's in the preparatory stance unless he gets attacked first.
• In Et Cetera, the Eto Gun and the Zodiac use various essences to fire bullets, which are based off of the Chinese Zodiac and the constellations, respectively. For example, you would need something from a cow to fire an Ox bullet, a fish to fire a Pisces bullet, etc. If there's no essence available, the guns are little better than the toys they resemble, being unable to fire.
  • Speaking of the Pisces bullet, it's created with essence from a fish, so it only works in the water. Unless the essence came from a flying fish.
• Eyeshield 21:
  • Kongo Agon has a reaction time that is close from inhuman, making him nearly impossible to shake off since he will always be the first to move. However to react he needs to see which allowed The Hero to smack him down from a blind spot.
  • Sena, the protagonist, can outrun most of his opponents in a straight dash, but he slows down and sometimes stops when changing directions, so opposing players need only to force him to turn in order to catch him. One of his techniques allowed him to avoid being tackled by making it look like he froze in time because of a sudden backstep and suddenly running at full speed after avoiding the opponent, but his opponent deduced that by speeding up the moment Sena backsteps, he'll be able to catch him. While Sena found ways to overcome these weaknesses, the sole weakness he could not overcome is the simple fact that there is somebody that he cannot outrun.
• Fabricant 100: As Roxy's Fabricant's power work if a human listens to her singing for a long time, No 100 makes a deafening scream and interrupts the effect.
• Fairy Tail:
  • Wendy Marvel, the Sky Dragon Slayer, can eat air (this is not the same as breathing) to increase her strength and heal herself. While she is potentially invincible, since unlike other Dragon Slayers, her element is everywhere, she'll get sick if she tries this when the air is polluted.
  • One of the antagonists, Cobra, both subverts and plays it straight with one of his strongest abilities: Telepathy. Since he can hear another's thoughts, you'd be forgiven if you thought it could be stopped by thinking different from what you're really gonna do or flooding your mind with multiple thoughts to confuse him. Nope, turns out he's aware of both those problems. However, it is rendered useless if his opponent isn't aware of those thoughts themselves. In other words, if his opponent attacks without thinking entirely, or rather, fights instinctively, he can't predict their actions. It also doesn't work on those who have no memory. Since he hears thoughts, he's also vulnerable to someone thinking in a misleading way; he's able to hear Natsu think about the "Fire Dragon's Roar" and an attack Cobra couldn't escape, making him think that Natsu was going to use his Breath Weapon (which he calls Fire Dragon's Roar), but Natsu was actually planning to exploit the fact that Cobra's power is based on extraordinarily fine hearing by literally roaring loud enough to knock Cobra out from the overload.
  • From the same arc, Midnight's Reflector magic is a clear example of winning the Super Power Lottery, being able to reflect attacks, turn the scenery and the enemy's weaponry against them, and create illusions by bending light. When Erza fights him, her armors and sword are useless, but she quickly figures out three major weaknesses — he can only manipulate one area at a time (so if he's trying to throttle her in her own armor he has to dodge her attacks the old-fashioned way), he can't reflect human bodies (so he can't reflect his way out of Good Old Fisticuffs), and his reflection power is useless on something that's naturally elastic (like Erza's Robe of Yuen), since it will just stretch and then return to its regular shape.
  • When Gray fights Sugarboy, who has the ability to make things softer, his Ice Make power is for the most part useless because Sugarboy can soften the ice up to the point where it's basically water. However, he can't change any other properties, so he can't make an ice-coated floor not be slippery. He also has to be careful with using his powers around an item he doesn't want to destroy (like the key he and Gray were fighting over), because he could accidentally soften it up too. Gray, meanwhile, doesn't have to bother protecting the key, because he can just copy it with Ice Make.
  • When Elfman fights Bacchus in the Grand Magic Games, he finds himself overwhelmed by his foe's strength and speed despite using various monster transformations. Finally, when Bacchus decides to go for the finisher, Elfman switches forms one last time to his Lizardman form, exploiting the fact that Bacchus' bare hands are incredibly vulnerable to being damaged on the tough, spiky scales of his body with the speed and force he's fighting with. The fight then becomes the question of whether or not Bacchus' hands can tear down Elfman's defenses before he reduces them to bloody damaged limbs and can't keep fighting, a clash that Elfman just barely wins.
  • Even the wizard king August falls prey to one. His ability to instantly copy any magic he encounters is one of the most broken powers in the series, which combined with his unmatched levels of raw magical power means he can almost always outdo people at their own techniques. However he can't copy magic that relies on tools he doesn't possess, like Cana's cards or Lucy's keys.
• Fist of the North Star plays with this trope:
  • Kenshiro's Hokuto Shinken relies on hitting an enemy's Pressure Points, so Shin sicked on him Mr. Heart, who is so fat Kenshiro can't hit his pressure points. This gets subverted because, much to Shin's shock, Hokuto Shinken has a move to push away an enemy's fat (and another to hit an opponent's pressure points with an energy attack, but that one showed up in a different fight).
  • This weakness resurfaces, to much more effect, when Kenshiro faces Souther, who, having Bizarre Human Biology in the form of situs inversus totalis, has all the pressure points switched around. This invulnerability also vanishes if the Hokuto practitioner can figure its source — and while Kenshiro only manages during their rematch, Toki, a trained medic, knew it from the start.
  • Hokuto Shinken and Nanto Seiken practitioners are trained as assassins and formidable Combat Pragmatists who can sneak up on anyone except another practitioner. So they have no idea on how to deal with the rare opponent who can get the drop on them, like the Colonel (an experienced soldier and Nanto practitioner, who fought Kenshiro on a terrain that gave him a huge advantage and managed to last much longer than he had any right to) or Yuda (who is just that dirty, and a Nanto practitioner to boot. Rei beat him only because Yuda stopped to gloat before the finishing attack and froze up at the beauty of his desperate counterattack).
  • Rei's Nanto Shuicho Ken technique relies on fast and graceful movements, and thus on his legs. Yuda gains the upper hand in their fight by flooding the whole area, thus making him sluggish (and, to play it safe, kept the distance while spamming an attack that worked at distance, something Rei has no equivalent of).
  • Subverted with Shuu: he's blind, so some of Souther's soldiers guessed they would disorient him by surrounding him and make lots of noise... except that he's a top-tier martial arts master who's far too experienced to ignore such an obvious weakness, and he's had years to come up with a counter to that and pretty much every other way that an opponent might exploit his lack of eyesight.
  • During his temporary blindness, Kenshiro found himself in a similar situation. He swiftly dealt with his attackers thanks to his new ability to summon the skills of his late allies, including Shuu.
• Food Wars!: Soma is a very experienced and skilled chef, and has worked on-and-off at his dad's "special-of-the-day"-restaurant since he was three. However, he is clearly out of his depth when faced with any situation when his experiences aren't applicable. He flounders with kitchen French, fails to consider his dish's staying power on a heat plate when devising a recipe for a buffet (a situation which would never occur at his dad's restaurant), can't keep up with cooking multiple multi-course meals (as opposed to single dishes, one at a time), and struggles with making the type of high-impact foods that win cooking contests, as opposed to the "enjoy-the-meal" style he's used to.
  • Mimasaka Subaru's "Perfect Trace", a skillset which allows him to perfectly replicate other chefs' styles and dishes so that he can subtly improve them, is shown to be quite formidable. However, there are gaps that can be exploited. First of all, an opponent who knows what is happening can (albeit with some difficulty) take steps to ensure that their recipe cannot be replicated. Second, a sufficiently skilled opponent can create a recipe Subaru is incapable of improving on (a tall order, since he is legitimately extremely skilled, but possible). Finally, he can only replicate the style of one chef at a time, meaning that he can be beaten by a well-coordinated team. He can replicate all the individual styles one by one, but being forced to learn them all and switching between them is extremely taxing.
• Fullmetal Alchemist:
  • Alchemy in general can, in practice, transform or reshape practically anything into anything else as long as you're dealing with unliving things — but you do have to have enough material and use it in a logical way, which leads to Ed being unable to build a bridge over a chasm because the rock breaks under its own weight and he hasn't got an unlimited amount of it to use. Scar also kills a particular state alchemist by tackling him into a river. With nothing in reach except water, the alchemist couldn't transmute anything useful.
  • Ed and Al's alchemy, thanks to receiving knowledge from the Gate, is much easier to use than most since they don't need to make an alchemic circle and just need to clap their hands together. Of course, while this is incredibly useful and versatile, it requires the use of both functioning hands. Many times Ed and Al have been stopped from using alchemy by something as simple as their hands being bound...or just losing an arm. Thank goodness for the fact it's the replaceable limbs that get wrecked, and the fact they can still draw alchemic circles.
  • The fact that Roy Mustang is useless when it's raining is something of a Running Gag. This is because, well, he uses fire, and rain is going to put a bit of a damper on his ability to get a flame going. However, this is only when he himself (specifically his hands) are wet, because if something else is covered in water he can just decompose it into hydrogen and oxygen then ignite that. This is because his gloves are made from a special material called ignition cloth that cause a spark when he snaps, when combined with transmutation circles on the back let him do his alchemy. Give him another source of flame (like a lighter) and he can overcome them being wet. In fact, he arguably becomes more dangerous, because he now has all the hydrogen and oxygen he could ever need readily available (water's molecular structure is very simple, making it easier to manipulate), but the problem now is that unless he traps the enemy into an enclosed space with the water, the resulting massive and more importantly imprecise explosion is just as likely to hit any nearby allies or himself.
  • Pride's Living Shadow powers don't work in total darkness since he needs a light source to cast a shadow. It's also weak to the flashbang that Alphonse used since the light is too bright to cast a shadow (not to mention he uses the shadow to see).
  • Wrath has the Ultimate Eye that allows him to instantly predict what will happen in battle, allowing him to perfectly dodge, block, and strike no matter what the opponent does. The one weakness is that it's an eye, and its power is therefore sight-based: it cannot predict an attack if it cannot see the attacker.
    • Downplayed with Wrath's second weakness. Wrath's Philosopher's Stone only has one soul and life, making him the only homunculus without a regenerative healing factor, so he can be killed like any normal human being. However, he can still take far more punishment than a human being normally can, so even after being severely wounded and losing a lot of blood, he can still put up a good fight against his adversaries. He came close to killing Scar several times despite being on the verge of death.
  • Greed's Ultimate Shield allows him to cover his entire body with a nearly impenetrable barrier, making him more or less invincible. However, his shield is the result of Greed rearranging the structure of the carbon in his body in order to give it diamond-like qualities; an alchemist who knows how his power works can easily transmute his carbon shield into the carbon-based, and extremely brittle, graphite, making the shield completely worthless.
  • Homunculi in general possess a Philosopher's Stone acting as their core, which contains the energy they use for their powers and regeneration. Problem is, Philosopher's Stones are created through alchemical transmutation... and there's a reverse transmutation that instantly depletes a Stone of its energy. This is used to one-shot the homunculus Envy, reducing him into a nearly-harmless larva.
    • There's also the fact that the Philosopher's Stone is a finite energy source, so a homunculus can be beaten by sheer attrition, being constantly pressured with excessive force, and repeatedly killed to tax their regenerative power, as demonstrated when Roy Mustang incinerated Lust and Envy until they couldn't regenerate anymore, or when Sloth expended all his energy regenerating in his fight against the Armstrong siblings and their newly arrived allies. Not even Father can hold out for more than a few minutes against the combined assault of Ed, Izumi, Mustang, Armstrong, Greed/Ling, Lan Fan, Darius, Zampano, and the Briggs troops, and certainly not helping was that he was already taxing himself trying to keep Truth contained with a reduced collection of souls after losing the population of Amestris and wasting more defending himself.
  • Scar's right arm has incredible destructive power, but it still operates under the same premise as normal alchemy — he requires a knowledge of what he's transmuting before he can do it. He's failed to destroy Ed's automail arm twice due to this; the first time was because he didn't realize right away that it was automail, the second because he didn't know that it was no longer composed of steel.
  • Ed has to fight two human chimeras whose enhanced animal senses allow them to sniff him out no matter where he hides. Ed uses this knowledge to his advantage by transmuting a huge quantity of powerful-smelling ammonia from the ammonium nitrate in a cache of old dynamite he finds to knock them clean out via Sensory Overload.
• In Future Diary, police detective Keigo Kurusu's future diary feeds him data from whatever investigation he's currently conducting. The solution? Expose his Dirty Cop ways and get him kicked off the force, meaning he's not on any investigation, totally bricking his diary.
  • The diaries, in general, have specific strengths and weaknesses. As such, the survival game depends on how a diary user works around his diary's weakness. Yukiteru's diary, for instance, can predict events that happen around him, but not events that happen to him, so anything unexpected happening to him like suddenly getting stabbed or stepping on a mine he didn't notice will most likely kill him. Also placing him in a confined space limits the things his diary can predict. Yuno's diary perfectly augments Yukiteru's diary by being able to predict anything he does and everything that happens to him. The downside is that aside from the "Dead End" message, Yuno's diary does not predict events that happen to or around Yuno herself.
• Gleipnir: Sayaka Koyanagi can make Explosive Leashes out of her that she attaches to members of her group. If you disclose any of their secrets or betray them, then wave bye-bye to your head. But her power only activates if the target feels like they betrayed the group. It won’t activate if the target successfully convinces themselves they didn’t betray the group, like Ikeuchi did after he ran away and left the group to deal with Madoka and his men. Also, her power is completely useless against anyone who doesn't voluntarily let her use it on them.
• Guyver: All Guyver suits possess a "control medal" that give the user full control over the suit, in order to prevent the latter from going out of control. As a side effect, this also prevents a Guyver user to be infected by The Assimilator, because the medal automatically rejects anyone except its user.
• In Holyland, Tsuchiya's wrestling has three:
  • His best moves need him to go very low, even scraping the ground with legs, knees and hands. He found out the hard way that going that low on concrete is a quick way to harm himself, leading him to not use them unless he's on a soft terrain (he states the best would be sand, but a lawn is soft enough).
    • On the plus side, on his ideal ground kickers such as Masaki, Shogo and Yuu (the ones who defeated him, with the first being the one who exposed the concrete problem) would find that sand is too soft for them to stand on a foot while moving the other that fast, and Masaki and Yuu, who use boxing-style footwork, would find themselves heavily slowed down.
  • To avoid scraping on the ground, Tsuchiya goes with normal American Football-style tackles that expose the back of his neck and put his head in easy reach of kicks, making him extremely vulnerable against skilled opponents such as Shogo (who hit him with a downward punch) and Yuu (who kicked him in the head).
  • As a grappler, he was never trained to block or parry strikes. He usually wins by tackling his opponents faster than they could strike and then throwing him away, but when he faced Yuu, knowing his speed, uses a boxing semi-crouch stance, not knowing it relies on the gloves (that soften the blows enough for the arms to take them and enlarge the hands enough to prevent the fist from getting between the arms) to be effective.
• Hoshin Engi: When Chokomei goes One-Winged Angel and assumes his true form, that of a giant plant that spreads uncontrollably, Yozen deduces that since he is now a plant, all he has to do is kill the roots to get rid of it. But he realizes that it would be useless since Chokomei would just spread his seeds and grow faster than he could burn it. Taikobo then decides to use another logical weakness, and freezes the whole thing with one giant icy tornado.
• Characters in Hunter × Hunter are fully aware that their powers have shortcomings. Knowing their enemies will brutally exploit them in ways they don't expect, most characters keep them a secret even from the people closest to them until absolutely necessary. Those who reveal them prematurely or to someone who survives the encounter tend to wind up for the worse:
  • Princess Camellia has a Death-Activated Superpower in which anyone who kills her has their life force removed, then used to restore Camellia back to life and heal all her wounds. However, it only works if someone murders her. Her older brother, Prince Benjamin, catches on to this fact and just breaks her limbs without killing her, incapacitating her without allowing her power to activate.
  • Genthru is ultimately defeated by a group of people far weaker than he is because they figured out how his Mad Bomber powers work without dying in the process — namely, that for him to not be harmed by his own close-range explosions, Genthru has to put up armor out of Battle Aura concentrated on where the explosions are, leaving him completely defenseless everywhere else. Splashing flammable liquids onto him will also neutralize Genthru, as any attempts at said close-range explosions will set him on fire too.
    • On the other hand, Genthru's other power, the Countdown bomb, attaches itself onto people only after he explains its rules and how to defuse it to his victims. He considers this a major weakness, and he has to be stronger and faster than his victims by a significant margin to not be defeated before the bombs go off.
  • Gon defeats Gido, who spins like a top and is untouchable when spinning, without ever needing to use his own powers by simply lifting up the floor tile he's on, tipping Gido off balance.
  • Killua, while wandering through a forest, suddenly has dart-shaped fish materialize on him, puncturing his body wherever they materialize. Seeing a dartboard pattern projected onto the front of his body, Killua soon figures out the fish are materializing based on the sequence for a perfect game of darts and figures out where all of the remaining fish will materialize. The people responsible, a pair of siblings playing darts in a hidden location, don't have knowledge of Killua's condition. Knowing they played a perfect game and knowing that it insta-kills anyone punctured by all of the fish in the order corresponding to a perfect game, come over to confirm the kill — only for Killua to just impale them with their own dart-shaped fish.
  • Overlaps with Loophole Abuse when Cheetu transports Morel to an open savannah space and challenges Morel to catch him within six hours. Cheetu has Super-Speed, so Morel has no hope of catching him in a normal chase. However, Morel knows he doesn't have to run around futilely, and he catches Cheetu in a snare trap, rendering him hanging upside-down from a tree and allowing Morel to easily win this game. Also a case of Didn't Think This Through because Cheetu admits, upon his defeat, that everything would've gone back to normal had time run out. The power literally has no effect other than to waste time.
• Expanded Domains in Jujutsu Kaisen often apply an unavoidable effect to everyone in the area except the Domain's creator. Which means that it will also hit people the user doesn't want to hit - like when Gojo is surrounded by innocent people who would be rendered insane by his Unlimited Void. Or when Mahito is facing Yuji: Mahito's Domain makes it so that the soul of anyone inside is automatically touched by him, and Yuji's soul contains Sukuna, who can and will retaliate against Mahito if he touches him.
• Subverted in Kill la Kill: Gamagoori's Three-Star Uniform is powered up by being attacked in its defensive mode, so Ryuko thinks she can avoid triggering its second form (Combat Tentacles) by just not attacking. At that point, Gamagoori reveals his uniform can just trigger the second form manually by simply flogging itself.
• Kindergarten Wars: Haruo fights by using fireworks. Unlike Hana's grenades, they don't work if they are wet, so Doug blows up a fire hydrant to wet them.
• The manga of Kingdom Hearts: Chain of Memories has Larxene defeated in such a way. Sora and Donald combined their Fire and Ice spells to soak Larxene with water, causing her lightning spells to electrocute herself instead. This doesn't work in the game.
• Life with an Ordinary Guy who Reincarnated into a Total Fantasy Knockout: Tachibana is turned into a Living Aphrodisiac girl, who can make any one fall in love with him. That said, obviously this body is still that of a woman, and it only attracts people that are already attracted to women. Telolilo, who is a straight woman, and Shen, who is a gay man with a preference for muscles, are both completely immune to the charms of that body.
• Medaka Box loves this trope.
  • The best example is probably the array of weaknesses that Yukuhashi Mizou's abnormality, mind-scanning, has, thanks to it working really, really well. Catching even the smallest thoughts, he can't decipher input from a person who does not think clearly and jumps from one thought to another fast enough for it to be of use; he cannot function in crowds by himself, due to being overwhelmed by the stream of thoughts; he feels pain that the people within his reception range feel; and, finally, he cannot fight a good person who honestly had legitimate reasons to oppose him, without seeing how they think and starting to empathize with them.
  • Medaka's own ability, The End, which allows her to copy and perfect anything used against her, is incredibly good, but it has two major weaknesses. First, she's forced to sit out several major fights because the opponents had powers she wouldn't want to copy (like a hitman whose power is bloodlust — The End would perfect it to the point where Medaka became a rampaging psychopath). Second, while she can copy powers, she can't copy things that require self-expression, meaning she has No Social Skills and fails at any form of artistic expression like music; even if her performance is perfect in a technical sense, it lacks any kind of passion and thus comes off as utterly boring and mildly disturbing. Because of this, she can't copy Styles.
• Shows up at several times in Monster Musume. The literally cold-blooded Miia is susceptible to cold temperatures, Centorea Shianus' giant breasts actively interfere with her coordination and balance during combat, Papi can't fly when she's wet, Suu can get diluted when exposed to too much water, Meroune gets poisoned by swimming in chlorinated water the same way a human would by breathing bleach fumes, and Rachnera can't handle extreme heat or cold and cannot breathe if her nonhuman abdomen's underside is submerged (that's where spiders have their respiratory orifices).
• MOON – Subaru Solitude Standing has Nico, a blind ballet dancer. While his other senses improved to an extent, his blindness remains with its logical weaknesses. He needs to feel the ground and objects when he's in unfamiliar rooms, and he can't dance duets. He can feel energy from other dancers, but most of them are so faint that it would be difficult to impossible to dance well with them. The fact that Subaru manages to send out enough energy to allow Nico to dance with her is considered an amazing feat.
• In one episode of Myriad Colors Phantom World, the protagonists battle a Phantom that resembles a humanoid sunflower. It effortlessly blocks their initial attacks until Koito realises that, because it's a sunflower, it always turns to face the sun. They're then able to defeat it by simply walking around it and attacking from behind.
• Several techniques in Naruto are held back from being Story Breaker Powers by limits that are by-products of their usage or make up.
  • Naruto's Rasen-Shuriken attack is essentially a flechette bomb that attacks organisms' individual cells. It has a tendency to do this to the person who is holding it as well as the target, hence why Tsunade labels it forbidden jutsu. He overcomes this with Sage Mode as it allows him to throw it.
  • Kinkaku and Ginkaku subvert this with one of their ninja tools, which causes people to be sucked in if they say the word they say most in life. You'd think it would be easily avoided by just not saying anything, but remaining silent long enough also gets you sucked in.
  • Shikamaru's shadow powers, which often require his shadow to touch the enemy's, are often influenced by the amount of light available. For example, one Filler Villain manages to escape his jutsu with a smoke bomb.
  • Water jutsus often require existing sources of water to be effective. As such, one Filler Villain (who uses his Twin Tonfas as dowel sticks) is defeated by being lured to an area with virtually no groundwater.
  • Tobi's abilities make himself intangible. Of course, he can't attack while phased, since it would just go through his foe. The best time to attack, then, is when he attacks. He does try to get around this when fighting Minato by using chains that trail behind him, in order to catch foes who he phases through.
  • Also, due to shared Mangekyo Sharingans, Tobi's phasing is absolutely useless against Kakashi; he can match phases with Tobi and attack him either way.
  • Sharingan users do not gain any Required Secondary Powers to any techniques they copy; they are still subject to the particular shinobi's personal limitations. Sasuke's attempts to copy Lee's taijutsu being the most cited example (Lee is a taijutsu specialist due to a lack of aptitude in the other arts, so his body is at a level of conditioning the more-balanced Sasuke can't match).
  • The Sharingan is an eye power, meaning it grants enhanced perception but no physical enhancement. A Sharingan user can see an attack coming and still not be able to actually defend against it if they aren't strong or fast enough. For example, in their fight, Sasuke blocks Lee's kick but Lee is so much stronger and faster for it to not matter. Similarly, the human eye can only track so many objects at once. While fighting Killer Bee, a number of hits Sasuke takes are due to futilely trying to track both the man himself as well as his seven swords which he often threw in the air.
  • Rock Lee has a really obvious weakness that stops him from being among the strongest ninja: He can't use ninjutsu or genjutsu, two-thirds of the fundamental ninja arts. So while he can move and hit hard he can't defeat illusions or enemies that can counter physical attack (his rival Neji for example can reflect any attack with his Eight Trigrams Palms Revolving Heaven jutsu and his Gentle Fist attacks organs and chakra points which no amount of physical conditioning can stop).
  • On the other end of the spectrum, the specific taijutsu style utilized by the Hyūga clan, demonstrated as early as the Chūnin Exams arc, exploits an inherent logical weakness in all human beings: using their Byakugan, the Hyūga are able to see the chakra networks of others and use their own chakra-based abilities to attack both the chakra network and internal organs of their opponents because, (as mentioned above with Rock Lee) no matter how hard you train your body, you can't strengthen your heart or liver and whatnot.
  • When fighting Sasuke, Danzo summons a Baku, a creature with a powerful Vacuum Mouth. Sasuke opts to launch a fire jutsu into its mouth when it tries to suck him in a second time, causing it to retreat.
• In Negima! Magister Negi Magi Negi gets superspeed by turning into lightning. This is countered by Rakan pointing out that lightning gives off positive streamers at the destination meaning he knows where it's going to strike. Because his perception isn't sped up as well he can't properly control himself. The upgraded version fixes this by giving him those sped-up perceptions and having him fight at very short range as opposed to his previous hit-and-run style, giving an opponent almost no time to react.
• Neon Genesis Evangelion has a few:
  • A giant machine/cyborg like an Evangelion Unit would need an enormous amount of power to function. The best NERV can do is provide a giant cable for the Units in question, and sure enough the cable always gets destroyed at the worst possible time.
    • Once the power ("umbilical") cable is cut, the Evas switch over to internal batteries that provide 1-5 minutes of power (depending on the current plot). Naturally, there's a few occasions where these run out as well.
  • During the fight against Zeruel (the strongest of the Angels), Shinji is able to achieve an astonishing 400% sync ratio with his Eva. The Angel is then obliterated in a Curb-Stomp Battle, but this has very serious consequences for Shinji: his body dissolves into LCL and his soul floats around in the entry plug, and Nerv has to work to restore his body and soul before Eva-01 absorbs him for good.
• In Ninja Scroll, the antagonists are the "8 Devils of Kimon", a group of ninjas with extremely powerful supernatural abilities. However, main protagonist Jubei is able to think up counters to the abilities based on this, which is often key to overcoming them.
  • The massive brute Tessai can turn his skin to stone, making him immune to blades, which bounce off him harmlessly. This does nothing to protect him from being poisoned, and during his first encounter with Jubei, Jubei says that not all of Tessai's body can be hard as stone, and proves it by tossing a throwing dagger into Tessai's eye.
  • Mushizo has transformed his own body into a hive for wasps, which he controls telepathically. Jubei knocks him into a lake, which not only break Mushizo's control of the wasps, but because their hive is now flooded, they desperately try to escape by trying to sting and dig their way out of Mushizo's body.
  • Utsutsu Mujuro is a Blind Weaponmaster. Jubei first attempts to lure him into a bamboo wood, only to find that Mujuro's senses are so sharp he is still able to navigate the woods freely. Later, Jubei uses an obstacle that Mujuro cannot track by sound to block Mujuro's attack, then counterattacks in the brief window of opportunity.
  • Zakuro uses the large quantities of gunpowder that she always carries with her to create explosions and set bombs. Dakuan soaks her in oil and Jubei sets her fire, which doesn't just kill her, but also sets off her gunpowder stores, destroying the ship she was on and which was integral to the plan of her boss.
• Qualia the Purple: Hatou's left arm functions as a cellphone and even allows her to communicate with parallel universe version of herself. But she is also its battery, so she has to be careful to not overuse it and tales to eating sugary snacks to keep her energy up. She even mentions that she lost 2kgs over the span of a weekend from using her cellphone-arm without replenishing her energy.
• Rave Master: During one battle, Haru is facing a mind-reading opponent, so he comes up with an unusual use for Rune-Save, a magic sword whose power is based on sealing. He invokes its power to seal his own mind long enough to land a combo that defeats his opponent.
• In Reborn to Master the Blade, Inglis finds her city's knight order being humiliated in friendly sparring matches by a merchant's son using magic to cheat, Rahl. She realizes that the spell slows the reaction time of anyone that is looking directly at Rahl. It does not work when the opponent is attacking Rahl without looking at him or simply keeping your eyes closed so the magic has no chance to take effect.
• Rosario + Vampire:
  • As a yuki-onna, Mizore is extremely vulnerable to fire and heat, as well as those who have fire/heat powers.
  • Kahlua Shuzen is a berserker who has been charmed to Feel No Pain, and while this makes her a dangerous combatant, it doesn't actually prevent her from taking damage, and prevents her from realizing how much damage her body's taking until it simply quits on her.
• When the title character of Rurouni Kenshin fights an opponent with a BFS, he's able to out maneuver them by the sheer fact that with a blade that big and heavy, their range of motion in regards to attacks is limited to sideways slashes and overhead chops.
• Serial Killer Reincarnated In Another World: The titular Serial Killer Shirukyi has to assassinate twelve all-powerful reincarnators that are blessed with overpowered cheats in order to save the world from their tyranny. Luckily, said reincarnators tend to overlook the obvious weak spots that come from depending on their cheats too much which is instrumental for Shirukyi in carrying out their downfalls.
  • Ouga has Status Inspection as his cheat which lets him kill off those weaker than him and counter their attacks by seeing their levels and powers. However, this makes him very cautious about taking any risks, meaning Ouga never challenges himself in battle unless he's absolutely certain he will win, and overconfident in his undeveloped strength and skills against under-leveled people. Thus, he severely underestimates Shirukyi for their novice levels and stats, gets himself lured into the deepest part of the dungeon and is forced to fight an S-class monster he usually stays away from. By the time he defeats the monster, Ouga has already exhausted his power, magic and body to their limits, and is easy prey for Shirukyi.
    • Ouga is also shown summoning his signature broadsword by reaching his right hand into his personal Pocket Dimension and pulling it out. When he tries fighting back against Shirukyi, they easily disarm him by stabbing their dagger through his hand and pinning it to the ground, preventing any access to his blade.
  • Yamazaki's Malicious Perception detects anyone with Killing Intent towards him, making him nigh-impossible to sneak attacks while also having the drop on his would-be assailants. This initially gave Shirukyi a hard time until they realise the radar cannot detect people who don't have any malicious intentions or know what they're doing like say a naive orphan instructed to shoot a crossbow blindfolded on their signal as just a simple "prayer". Thus, the little girl unknowingly bypasses the cheat through her innocent nature and nails the Yakuza in the back with a poison-tipped bolt, weakening him enough so Shurikyi can deal the final blow.
  • Silsil and Milmil have the joint cheat of Great Resonance that lets them rapidly release and amplify their vast magic into one another in a never-ending cycle, resulting in limitless magical power that puts any Wave-Motion Gun to shame. Shirukyi, however, simply exploits the fact that the cheat requires both twins and for them to be in close proximity to activate and separates the two by exploding the ground underneath Silsil, trapping her on a lower floor of their tower with them, while Milmil is left to deal with a newly-released Lunatic at the top. Once Lunatic brutally killed Milmil, the cheat is gone forever as her even if Silsil is still alive (Technically).
    • Additionally, their co-dependency on each other and heavy reliance on magic made the sisters Squishy Wizards by nature. While this is somewhat compensated by being immune to all types of Anti-Magic weaker than their magic (Something Sacred had tried taking advantage of but failed), this doesn't apply to their own magic (Silsil gets caught in the tower's magic destruction barriers she set up) or magical beings way more powerful than them (Milmil finds herself completely outmatched by Lunatic as payback for locking her up). Otherwise, Shirukyi likens their solo "battles" as "easy as murdering a weak, defenseless woman".
  • Expanding upon the above incident, Sacred confidently went up against the twins wearing the rare Jewel Of Magical Destruction which not only cannot be destroyed by any means necessary but absorbs 99.9% of all magic attacks which are Milmil and Silsil's main and only form of combat. What he didn't expect was the twins to suddenly bust out Great Resonance and made him realised that (a) the Jewel of Magical Destruction doesn't grant the same invulnerability to its user and (b) 0.1% of infinite magic is still infinite. Predictably, Scared never stood a chance from the start and paid the price by being vaporized into oblivion with the still-intact amulet left for the two's nefarious uses.
• The Seven Deadly Sins:
  • Ban has Complete Immortality and can heal from pretty much any injury. He's still vulnerable to things like being petrified and getting his soul stolen.
  • The Ten Commandments all have incredibly powerful abilities, but although each Commandment has an immunity to the other nine Commandments, they are not immune to their own power, forcing them to limit their own actions. For example, Galan turns to stone anyone who lies or breaks an oath in his presence. He Cannot Tell a Lie lest he fall victim to his own ability (which eventually happens when he panics and runs away from Escanor after they had both sworn an oath that they would keep fighting until one of them was dead).
  • Estarossa of the Ten Commandments has the Commandment of Love, which drains the strength of anyone who harbors hatred towards him, making them unable to fight. This has no effect on Escanor: as the Lion Sin of Pride, he is so confident in his abilities that the only thing he can feel for his enemies is pity, not hatred.
• Episode 7 of Space Patrol Luluco revealed that Life Fibers (being made of thread) are incredibly flammable.
• Spy X Family:
  • Anya might be able to read minds, but there are a few reasons this isn't a Story-Breaker Power:
    • She can be thrown off if her target thinks too fast for her to keep up, which is often the case with Loid.
    • Yor's thoughts involve such ultra violence that while Anya is used to it, it still scares the crap out of her.
    • Trying to cheat on tests with said power doesn't work if everyone else is panicking over the test.
    • Anya can read the minds of animals, but their thought processes are different enough to make understanding them difficult.
  • Bond can see into the future, but there are several factors preventing this from being as useful as it could be (aside from the fact that he's a Big Friendly Dog):
    • He has no control over when his visions of the future appear and can't call them up deliberately, meaning if he wants to know something about the future, he has to just hope his powers kick in at the right time.
    • He also has no control over the content of his visions, meaning that more often than not he only gets unimportant information of the "what we're having for dinner tomorrow" variety rather than anything that could be helpful.
    • Even if he does get a vision with useful information, said information is devoid of context and can involve things he has no current knowledge of, such as showing him visions of people he hasn't actually met yet. As a result, even if he has the info, he often can't act on it in a meaningful way until the events of the vision come to pass.
• In Tiger Mask W the immense Bigfoot was immediately identified as being poor in ground fighting due his own bulk hampering him and having low stamina due all his fights ending in five minutes. In his fight with Tiger Mask it ends up subverted because he or his trainer could guess the weaknesses, so he trained himself to overcome them (he actually almost kills Tiger Mask in ground fighting, and Miss X states his stamina is unrivaled).
  • Haruna is immensely talented, and as Spring Tiger is a force to be reckoned with... But she's also unexperienced and completely self-trained, and more experienced divas can counter her with relative ease.
• Mikey in Tokyo Revengers fights using his roundhouse kicks. Kazutora takes advantage of this by luring Mikey to having to fight Chonbo and Chome on a heap of cars where there's bad footing, preventing him from landing solid hits with his kicks.
• Toriko has the horrendously broken "Minority World" ability, which allows the user to invert chances and properties of pretty much anything. For example: making falling objects go up instead of down, the ground soft and malleable instead of hard, attacks miss instead of hit, and lungs taking in carbon dioxide instead of oxygen (which will eventually kill people). However, you can counter this by purposefully doing the opposite of what you intend to do — for example, aiming your attacks away from your opponent so that Minority World will make them hit instead.
• Tel Tel Boy/Dialbolic in Ultimate Muscle is a humanoid cell phone. This gives him two major weaknesses - he has no neck, and thus cannot turn his head, giving him a massive blind spot, and being mechanical renders him vulnerable to water. Mantarou exploits this by dialing time-and-temperature on him before tricking him into breaking open a hole in the ceiling - Mantarou knew it was going to rain at a given time.
• Keima, the main character of The World God Only Knows, is a legendarily skilled player of Dating Sims in which one pursues girls. However, the opposite of this (girls pursuing him) frequently leaves him at a loss.
• Zeno in Yona of the Dawn has perhaps the most broken power of the Four Dragons. If injured, his body will mend itself with dragon scales, which grants him superhuman strength. Coupled with his Complete Immortality, he's formidable to behold. The problem is that this power only activates when he's injured, so it's possibly to bypass this power by grappling him or tying him up. Worse, since he was a skinny teenager when he became immortal, and doesn't age or grow, he can't improve his baseline strength.
• YuYu Hakusho:
  • Kaito's ability to steal the soul of anyone who says the forbidden word is useless if no one speaks at all. Kurama, who has figured this out, proposes an alternative in which the condition gets stricter over time, and convinces Kaito to accept by adding the condition that if neither of them has violated the condition when the time has expired, Kurama will lose his soul, putting Kaito at an advantage. Ultimately, Kurama defeats Kaito by getting him to laugh, a process where his voice inevitably makes several forbidden sounds.
  • Much earlier, a demon tries to cast an incantation to shrink Yusuke. However, the spell backfires and shrinks him instead. Genkai explains that these kinds of incantations rely on a receptive ear, and as it turns out Yusuke's ears were inadvertently plugged at the time, leaving only one target for the spell.
  • Yusuke also manages to handily take down a mind reader; the mind reader knows exactly what he's about to do, just not when. Yusuke's attack comes so quickly once he actually started moving that the mind reader couldn't react quickly enough to avoid it.
