->'''Mike''': Whenever she uses her powers, she gets weak.
->'''Lucas''': Like, she flipped the van earlier. It was awesome.
->'''Mike''': But she's drained. Like a bad battery.

* In ''TabletopGame/{{Shadowrun}}'', spells cast at 'safe' levels (i.e. lower Force than the magician's Magic stat) [[CastFromStamina cause stamina damage as drain]]. Roll badly enough, or [[CriticalFailure Critically Glitch]] a Drain resistance roll, and this trope comes into play.

* ''WesternAnimation/AvatarTheLastAirbender'': The first time Aang enters the Avatar State in the pilot episode and several times in the first season before he gets used to it, he is visibly exhausted afterward. By Season Two, he's typically okay even if emotionally distressed.

* ''WesternAnimation/TheLegendOfKorra''; In the OriginsEpisode, Wan's first attempt at merging with Raava and using all four elements burns though his energy rather quickly and causes him to pass out. Once he fully fuses with her and becomes the First Avatar, he doesn't have this problem any more.
* In ''WesternAnimation/WolverineAndTheXMen2009'', Christy faints after using her [[DishingOutDirt earth powers]] to protect herself, her father, Wolverine, and Mystique from an explosion.
* In the 1990s ''WesternAnimation/XMen'' animated series, Jean does this after using her powers on Juggernaut to give him LaserGuidedAmnesia. She does so again in a later episode, after showing Candra the truth of the Assassin's betrayal.

* Happens to Orrick in ''Webcomic/UndeadFriend'' [[http://undeadfriend.com/comic/undead-friend-chapter-04-page-30/ upon turning back into a human after temporarily being a zombie for the first time.]]

* ''Series/TheMandalorian'': The first time The Child uses [[Franchise/StarWars the Force]] is to lift an enormous, rampaging mudhorn a few feet into the air. The effort is so draining he immediately passes out on letting the mudhorn go and remains unconscious for at least a day.

* ''WesternAnimation/ElenaOfAvalor'': Since the power of the Scepter of Life is CastFromHitPoints, Elena becomes weaker and more tired the more she uses it. When using it to defeat Orizaba, she uses so much power she ends up passing out for three days.

** ''Film/AvengersEndgame'': When Professor Hulk uses the Infinity Gauntlet to bring back everyone who was dusted in ''Infinity War'' he faints soon after with a charred arm. It speaks a lot about the power of the Stones that only Hulk and Thanos can just barely withstand the blowback of the combined energy [[spoiler: as poor Tony Stark (a mortal man) died when he used the Gauntlet]].

Compare to FaintingSeer, which may overlap for {{Seer}}s. May overlap with CastFromLifespan, and usually will overlap with CastFromStamina. Subtrope of {{Fainting}}.

* In ''WesternAnimation/WolverineAndTheXMen'', Christy faints after using her [[DishingOutDirt earth powers]] to protect herself, her father, Wolverine, and Mystique from an explosion.

* In the ''FanFic/FacingTheFutureSeries'', Danny does this whenever he comes out of his out of control SuperMode.

* In the ''Fanfic/EngieMainMultiverse'', [[UnevenHybrid Napaj-7]] [[ShockAndAwe Ash Ketchum]] suffers one of these after instinctively absorbing and releasing a bolt of lightning.
--> '''Ash''': I, uh, I think I may need medical attention... (collapses)

* In ''Film/TheHobbitTheBattleOfTheFiveArmies'': Galadriel faints after using the full extent of her magic to drive Sauron out of Dol Guldur.
* ''Film/ShinGodzilla'': When Godzilla uses its nuclear breath for the first time, [[spoiler: it's enough to absolute annihilate most of Tokyo but uses up so much energy it goes into a comatose state for two weeks, allowing the humans to plan a strategy to neutralize Godzilla when it wakes up]].

* ''Film/AvengersInfinityWar'': [[spoiler: Scarlet Witch collapses after using her full power to simultaneously destroys the Mind Stone (along with Vision) and hold back Thanos. Though to be fair Wanda does recover fast and attack Thanos when he cheats and uses the Time Stone to undo what she did]].
* ''Film/AvengersEndgame'': When Professor Hulk uses the Infinity Gauntlet to bring back everyone who was dusted in ''Infinity War'' he faints soon after with a charred arm. It speaks a lot about the power of the Stones that only Hulk and Thanos can just barely withstand the blowback of the combined energy [[spoiler: as poor Tony Stark (a mortal man) died when he used the Gauntlet]].

* ''Film/BirdsOfPrey2020'': Black Canary once she unleashes the full extent of her signature Metahuman ability the [[MakeMeWannaShout Canary Cry]] to send some {{Mooks}} flying, collapses in exhaustion.
* In ''Film/Freaks2018'', Chloe faints twice after a massive outburst of power.

* In ''Literature/ColdObsidian'', battle mages work in groups of seven where one mage concentrates on attacking spells, another - on protecting spells, and the rest of the group - donors - provide magical energy for them. It's not uncommon for a donor to blackout after a battle or even in the middle of it.

* ''Series/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 ''Series/KamenRiderKuuga.''

* In ''Webcomic/{{Spacetrawler}}'', Eebs (or humans like Yuri with Eeb brain implants) will black out if they strain their telekinesis by moving objects that are too massive. Too much of this strain can outright kill them. [[spoiler:It's later revealed that this limitation is a result of brain-clamping--we've yet to see an upper limit on how much matter an unclamped Eeb can move telekinetically.]]

* This happens to Danny ''all the time'' in ''WesternAnimation/DannyPhantom''.

* Wrestling/DwayneJohnson blacked out after filming the scene in ''Film/Hercules2014'' where Hercules roars, "I AM HERCULES!!" and [[BreakingTheBonds breaks free of his chains]], since they used real chains and he also strained his lungs to the limit with the scream.

* In ''TabletopGame/{{Shadowrun}}'', spells cast at 'safe' levels (i.e. lower Force than the magician's Magic stat) [[CastFromStamina cause stamina damage as drain]]. Roll badly enough, or [[CriticalMiss Critically Glitch]] a Drain resistance roll, and this trope comes into play.

** ComicBook/{{Rogue}} faints after some time if she [[PowerCopying absorbs the powers]] of a sufficiently strong superpowered person, such as Magneto. Though this DependingOnTheWriter as Rogue has absorbed power from the likes TheJuggernaut as well as [[ComboPlatterPowers multiple heroes]] with little to no ill effects.

* In ''Webnovel/ColdObsidian'', battle mages work in groups of seven where one mage concentrates on attacking spells, another - on protecting spells, and the rest of the group - donors - provide magical energy for them. It's not uncommon for a donor to blackout after a battle or even in the middle of it.

* Thistle of ''Webcomic/DaughterOfTheLilies'' passes out after [[http://www.daughterofthelilies.com/dotl/440 using lots of magic]].

If the fainting is a symptom of a more serious health problem, it's also a case of HeroicRROD. When it happens the first time a power is used, it's related to HowDoIShotWeb. Can be a form of BlessedWithSuck.

* In ''Fanfic/LovedAndLost'', Twilight Sparkle uses a shrinking spell Prince Jewelius showed her a few chapters earlier to turn Queen Chrysalis and her entire Changeling army tiny enough to fit a glass jar. She becomes exhausted and faints while Jewelius seizes the power from the princesses. She wakes up to find her friends, brother and the princesses driven away by Jewelius who has made himself Equestria's king. He even manages to [[CorruptTheCutie poison her mind]] and fill her with hatred towards her loved ones.

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