History LogicalWeakness / LiveActionTV

* ''Series/{{Haven}}'': All of the [[DifferentlyPoweredIndividual Troubles]] are rife with BlessedWithSuck (special shout-out goes to Dwight, whose power is that he ''attracts bullets''). But this trope applies most to Audrey, who is actually [[AntiMagic immune]] to the Troubles. This is almost always a positive, because it means Audrey has RippleProofEffectMemory and isn't affected by Troubles that induce fear or psychosis. But it's a drawback when the Troubled person is a RealityWarper. She can't perceive the Trouble and therefore can't help as easily. In "Sins of the Father," a gravedigger's Trouble makes the ghosts of dead citizens seek out loved ones to exact revenge on their behalf; at one point, she and Nathan are surrounded by them and they're about to attack, but Audrey, being immune, can't see them.

* In ''Series/{{Alphas}}'' it's pretty well-established that with every alpha ability comes a weakness of some sort. In early episodes, the most notable was Rachel, who has hyper, [[Series/TheSentinel Sentinel]]-esque senses. She was initially shown to be able to enhance one sense at a time, but while she did so, she couldn't use her other senses (while her vision or smell was enhanced, she could not hear the other characters when they spoke to her). This is a great weakness, which makes all kinds of sense. However, the writers seemed to have forgotten about this weakness, as in later episodes, she used her abilities without shutting the rest down; her weakness these days seems to be the fact that ''everything'' is ''always'' cranked up to eleven for her, which is actually less fun for your dating life than you would think. She even had them ''permanently enhanced'' later, though she seemed to be handling it better than at first.

** In "I Fall to Pieces", the MonsterOfTheWeek, Ronald Meltzer, had the ability of DetachmentCombat. He couldn't stay separated for too long or his parts would suffer necrosis from the lack of nutrients.
** "Blind Date" has Vanessa Brewer, a HandicappedBadass whose DisabilitySuperpower works by detecting energy sources, heartbeats, and breathing around her. As a vampire, Angel is faster than she is, only gives off heat while moving, and also doesn't have a heartbeat or need to breathe, so he moves in lightning-fast spurts to attack and then holds still so she can't sense him.
* In the Series/{{Arrowverse}} crossover ''Series/CrisisOnEarthX'', Thawne has to weaken Overgirl with red sunlight to negate her invulnerability before he is able to proceed with a life-saving heart transplant, since he wouldn't be able to cut her skin during surgery while she has her powers.
* In ''Series/BabylonFive'', when using telepathy to determinate what someone knows, it only reveals, well, what that person knows. If said person is misinformed, the telepath will not be able to determine the truth. When Lord Refa uses a telepath to mind probe Vir to find out about Londo's scheme, he didn't take into account the possibility of Londo lying to Vir. In the end, [[spoiler: he walks into a trap and gets torn apart by angry Narns, who are understandably pissed considering he was the one who ordered the use of [[ColonyDrop mass drivers]] on their home world, a war crime so severe it even gets condemnation from the normally distant Vorlons]].

* ''Series/TheBoys2019''

** "Teacher's Pet" has Buffy and the Scoobies facing off against a She-Mantis. While it may be a demon, it's still a bug. The Scoobies are able to ward it off using cans of bug spray, and Buffy plays recorded bat sonar to paralyze it, since bats prey on mantises and hearing their sonar makes their nervous system "go to hell."
** In "Fool for Love" Spike points out a crucial disadvantage Slayers have versus vampires. For all their SuperStrength and SuperReflexes, a Slayer still needs a weapon to kill a vampire, whereas vampires always have their teeth. He gains the upper hand over the Chinese Slayer Xinrong (and Buffy, while relating the event) by taking advantage of their instinctive grab for the weapon at hand.

* ''Series/DarkMatter2015'': Two's dependence on her healing nanites to maintain her bodily organs prevents her from using Transfer Transit tech, since only organic components are copied, so her ExpendableClone wouldn't have nanites and would collapse.
** Since Two's nanites keep her in perfect health, they also prevent her from becoming intoxicated (if you consider not being able to get drunk a weakness).

** Grodd is smart, has superhuman strength (due to his abnormal size) and telepathy, but he's still a gorilla and gorillas don't have the physiology to speak so he's unable to. However, with his telepathy this is not a huge issue for him. Grodd is also an incredibly dangerous threat to much smaller humans who don't have his mental powers, let alone size and strength. However, when faced by someone like Solovar, a gorilla who is just as large, just as strong, cannot be mentally controlled, and has the benefit of being trained in hand-to-hand combat against his peers, Grodd is woefully outclassed [[spoiler: and [[CurbStompBattle suffers a curb-stomping]] at Solovar's hands]].

* From ''Series/{{Heroes}}'':

*** As an aside, [[BadassNormal Noah Bennet]] [[CrazyPrepared presumably has an entire manual full of these.]]

* Introduced in ''Series/TheInvisibleMan'' pilot, where Darien is unable to properly control the quicksilver gland, as it's triggered by adrenaline. He tries to spy on a soldier and a nurse getting it on, only for the arousal to cause him to be visible again, earning him a black eye from the soldier. This is solved by his brother teaching him some yoga tricks to exert a more precise control over the gland (to the point where he can selectively turn parts of his body invisible and even secrete quicksilver on small objects from his hands). It still pops up whenever the writers feel like it, such as when his leg turns invisible when he's in the presence of a naked woman, or when his dead brother Kevin is temporarily brought back in Darien's body. Kevin also has to learn the same tricks to properly control the gland. Additionally, the gland only affects the visible spectrum, meaning Darien still shows up on thermals. He's also cold while invisible, as most of the heat passes around him instead of hitting him. Finally, when his eyes are quicksilvered, he can still see since the process shifts his vision to operate on a different spectrum but since his brain cannot interpret the different frequencies, he can no longer see color.
* In ''Series/JessicaJones2015'' the villain Kilgrave has a CompellingVoice which he can use to order someone to do ''anything'', up to ''[[PsychicAssistedSuicide killing themselves]]''. However, there are some ways to combat this; his power doesn't work if the intended victim can't ''hear'' him -- [[spoiler:which Jessica and Trish use to protect the latter by way of noise-cancelling headphones]] -- and, obviously, he can't use his power if he can't actually talk; at one point Jessica shoves a napkin into his mouth to gag him. His compulsions are also able to be circumvented by LoopholeAbuse, such as when the instruction of "put a bullet in your head" (with the intent that the victim shoot themself) was ended when the victim had a bullet placed inside their mouth.

** The Lovelica [[MonsterOfTheWeek Bugster]] from ''Series/KamenRiderExAid'' is based entirely around ThePowerOfLove (appropriate, given that he's based off of DatingSim games), meaning that the normal method of defeating bugsters won't work with him. He's practically able to NoSell the heroes...that is until [[FallenHero Taiga]] expresses his true feelings, and Nico outright rejects Lovelica. Emu eventually overcomes this by reprogramming Lovelica to be vulnerable to regular attacks, [[spoiler: only for Lovelica to be used as a SacrificialLion for the debut of [[BigBad Kamen Rider Chronos]]]].
** The BigBad of ''Series/KamenRiderBuild'', [[spoiler: Evolt]], gets a powerful item called the Evol Trigger late in the series, which makes him immensely powerful [[spoiler: as in PlanetDestroyer levels of power]], but it also becomes his biggest weakness. If one disrupts the Trigger's connection to the [[TransformationTrinket Transformation Belt]] (by, say, striking it with sufficient force) it jams, which causes the overwhelming power it usually affords to its user to overload and paralyze them.

* On ''Series/TheListener'', Toby's telepathy requires the subject to be actively thinking about what he wants to find out, often requiring him (or his partner) to deliberately prompt the target with a leading question or statement. He's also limited in that he can only determine what the subject ''thinks'' is true, he can't read people with some kinds of organic brain problem such as those suffering from epilepsy, and he's encountered one genius-level criminal who can simply think too fast for Toby to understand what he's thinking.

* In ''Series/TheLostRoom'' many of the Objects have amazing abilities but also have serious weaknesses.

* ''Series/PokerFace'': Charlie’s LivingLieDetector abilities only detect outright ''conscious'' lies. So she’s still duped by people [[ExactWords saying things that are objectively true while concealing certain information]], as well as cases of BelievingTheirOwnLies.

* ''Series/ShadowAndBone''

* In ''Series/StarTrekTheNextGeneration,'' Data, the android, has the standard weakness to electricity and electromagnetic radiation. He's also too dense to float or swim, although he can survive underwater. He's said to be able to serve as a flotation device, thanks to an inflatable airbag that he probably installed to deal with his lack of buoyancy.

* ''Series/TerminatorTheSarahConnorChronicles'' reveals that Terminators can't swim - their metal endoskeletons make them far too heavy, although they are still waterproof and don't require air. They can also be temporarily disabled by powerful electrical shocks shutting down their systems, although they reboot in two minutes. And they set off metal detectors.

* ''Series/TheWheelOfTime'': Eamon Valda cuts off every captured Aes Sedai's hands and gags them to stop them making {{magical gesture}}s and [[MagicalIncantation speaking words]] for channeling the One Power. However, he knows that's a crutch and not all channelers require that. [[spoiler:He experiences this firsthand as Egwene channels silently with no gestures at all, and Valda did not expect her channeling to prove that effective.]]

** In one episode, a LiteralGenie grants someone the power to become invisible. He has to strip naked to make any use of it, which he considers a small trade off, although it makes going outside uncomfortable. Even more uncomfortable: he promptly gets hit by a car because the driver didn't see him. A previous "beneficiary" of the genie's wishes ended up with an inhumanly large, ahem, [[GagPenis manhood]]. He then keeled over from lack of blood to the brain when he got excited. And the paramedics had trouble getting him through the door while he was lying on his back.
** In "Trevor", the titular con gains the ability to become intangible after [[LightningCanDoAnything being struck by lightning]]. While he has the ability to pass through conductive objects, destroying them in the process, he's powerless against non-conductive materials. He's eventually killed when struck by a car - he can phase through the hood, but not the windshield.

* In ''Series/JessicaJones2015'' the villain Kilgrave has a CompellingVoice which he can use to order someone to do ''anything'', up to ''[[PsychicAssistedSuicide killing themselves]]''. However, there are some ways to combat this; his power doesn't work if the intended victim can't ''hear'' him -- [[spoiler:which Jessica and Trish use to protect the latter by way of noise-cancelling headphones]] -- and, obviously, he can't use his power if he can't actually talk; at one point Jessica shoves a napkin into his mouth to gag him.

The Scoobies are able to ward it off using cans of bug spray, and Buffy plays recorded bat sonar to paralyze it, since bats pray on mantises and hearing their sonar makes their nervous system "go to hell."

In the end, [[spoiler: he walks into a trap and gets torn apart by angry Narn, who are understandably pissed considering he was the one who ordered the use of [[ColonyDrop mass drivers]] on their home world, a war crime so severe it even gets condemnation from the normally distant Vorlons]].

** The title character has all five senses boosted to superhuman levels. He can see someone clearly in the dark from a couple blocks away, recognize different kinds of dirt by touch, etc. Unfortunately, this power came to him in adulthood, and he doesn't know how to control them. The writers got a lot of mileage out of this, especially in earlier episodes. He is also prone to "zone outs", where he focuses on one sense so much he ignores all other sensory data, usually to his detriment (he almost gets hit by a truck in the pilot episode because he is focused on a Frisbee fluting through the air).

** General Kirigan can [[CastingAShadow manipulate shadows]] to the point where they can cut through solid objects, but they're still shadows, i.e. vulnerable to intense light. Kaz escapes his shadow cut attack with a phosphorus bomb that blinds Kirigan and dissipates the shadows.

* An episode of ''Series/PowerRangersSPD'' has an already incarcerated villain with the power to teleport through reflections. When the blue ranger comes to question him, the reflective surfaces on his uniform covered, and he's made to wear sunglasses with non-reflective lenses. [[spoiler:He still manages to escape by [[BreakThemByTalking emotionally manipulating him]] until he cries a single, reflective tear.]]

** The Key can let you enter and leave the Room through any door anywhere in the world (and thus lets you travel almost everywhere) but it cannot be a sliding door and in order to open the door it needs a tumbler lock. If you're not careful, you can trap yourself.

* On ''Series/TheListener'', Toby's telepathy requires the subject to be actively thinking about what he wants to find out, often requiring him (or his partner) to deliberately prompt the target with a leading question or statement. He's also limited in that he can only read what the subject ''thinks'' is true, he can't read people with some kinds of organic brain problem such as those suffering from epilepsy, and he's encountered one genius-level criminal who can simply think too fast for Toby to understand what he's thinking.
