History Main / PowerStrainBlackout

* After practising her telekinetic powers by suspending a cigar in mid-air, ''Literature/Matilda'' is so exhausted she goes straight to sleep.

* Tom Jones allegedly fainted upon singing the long and loud final note in the theme song to ''Film/{{Thunderball}}''

* "Blackout Syndrome" appears in the climatic end of ''Anime/FutureGPXCyberFormula''. The tremendous g-force generated from driving a formula car over 580km/h around the roller-coaster downhill corner causes a driver to go blind for a few seconds. In Hayato's case, [[{{Determinator}} who pushes beyond 600km/h]], almost collapses in the final lap.

* "Blackout Syndrome" appears in the climatic end of ''FutureGPXCyberFormula''. The tremendous g-force generated from driving a formula car over 650km/h around the rollor-coaster downhill corner causes a driver to go blind for a few seconds. In Hayato's case, [[{{Determinator}} who pushes beyond 700km/h]], almost collapses in the final lap.

* U Go Girl from the short-lived Mike Allred ''ComicBook/{{X-Factor}}''. Her power would literally drain her energy and she'd more than occasionally pass out after using her whirly teleportation.

* Manga/SailorMoon usually faints or at least collapses and loses her Super form after using her Rainbow Moon Heartache attack in the S series, although that restriction on her Super form doesn't apply during [=SuperS=], probably because she's using a power source other than the Holy Grail in that series. She also has this problem in the first few episodes of Stars, when she first tries to become Eternal Sailor Moon, and like with [=SuperS=], the problem disappears once that becomes her default form when the Animamates start appearing.

* Luffy of ''OnePiece'' falls into this after some of his fights. Usually it's the result of blood loss or poison, though after Enies Lobby and Thriller Bark he passes out from the strain of his Gear 2 technique, which is basically increasing the speed of his blood flow- if it wasn't his rubbery body, the stress on his heart would kill him.

* In the ''DresdenFiles'' books, wizards feel fatigue when they use a lot of magic. Pushed too far, it certainly can cause a blackout.

* In the ''DresdenFiles'' RPG, as in the books, spellcasting causes physical strain on the caster in two ways: firstly, calling up ''any'' magic at all (well, any evocation, and any ritual magic over a certain threshold of power) damages the character's mental stress by a small amount. Worse, if they call up more power than they can use (either [[DesperationAttack in desperation]] or [[PowerIncontinence because they screwed up a roll]]), they have to take the excess as either ''backlash'', which is this, or ''fallout'', which is [[CollateralDamage worse]].

* Willow, of ''Series/BuffyTheVampireSlayer'', often collapsed after over-exerting herself during spellcasting.

* In ''Manga/CardcaptorsSakura'', Sakura sometimes collapses after transforming Clow Cards into Star Cards. She knows that doing so will build her power, so she rushes it.

* Rogue in ''ComicBook/{{X-Men}}'' faints after some time if she [[MegaManning absorbs the powers]] of a sufficiently strong superpowered person, such as Magneto.

Frequently used for powers that aren't very flashy in order to make them seem more dramatic, such as telepathy and other PsychicPowers. It's also frequently a characteristic of TheChick, a FauxActionGirl, a NonActionGuy and other non-combat oriented characters.

* In ''Tabletop/{{GURPS}}'', strenuous activities, some power uses, and spell-casting, all cost Fatigue Points (FP), and running really low on those can cause a character to suffer penalties to movement and other actions. If necessary, after running out completely, the character can go on to spend Hit Points (HP) in place of FP, and running out of those can eventually cause some kind of collapse.

* In ''Anime/DigimonAdventure'', little Kari emits a light so powerful that her Digimon allies digivolve on contact. However, she has trouble walking, and near the end of the episode, she keels over.

* In ''FantasticFourWorldsGreatestHeroes'', Reed experiences this after stretching far enough to close the Negative Zone portal. Unfortunately, he's high in the air when it happens.

* ''KamenRiderBlade:'' The title character passes out after all his early uses of [[SuperMode King form]]. So does anyone standing close enough to actually witness him using his final attack on a MonsterOfTheWeek. King Form is one of KR's 'so powerful it may be too much of a good thing' modes, such as were seen back in ''KamenRiderKuuga.''
** ''KamenRiderOOO'' sometimes passes out after using a full combo.
* ''TokusouSentaiDekaranger'' sometimes has Jasmine overtax her psychometry powers and become a FaintingSeer.
** In ''HikoninSentaiAkibaranger'' Nobuo collapses after he uses HeroicResolve [[spoiler:to transform in the real world for the first time]].

* In ''FantasticFourWorldsGreatestHeroes'', Reed experiences this after stretching far enough to close the Negative Alone portal. Unfortunately, he's high in the air when it happens.
