->''"A man or animal driven through terror to desperation, is endowed with wonderful strength, and is notoriously dangerous in the highest degree."''
-->-- '''UsefulNotes/CharlesDarwin'''

In RealLife, [[CombatBreakdown most physical fights get less dramatic as time goes on]]. What started out as two guys in their physical prime going at each other, if it goes on for ten minutes, becomes two guys bearing the accumulated injuries of ten minutes of fighting. Big hits become fewer and farther between, there's a lot more slow grappling, and it just [[WimpFight starts to look sloppy]]. Similarly if one opponent at any point becomes significantly more injured than the other, [[UnstableEquilibrium that disadvantage tends to persist throughout the remainder of the fight.]]

Unfortunately, this does not make for good storytelling, so when the heroes in most media start losing, that's generally because [[HeroicSecondWind they're about to come back from behind]] and win the fight in the end. After all, it wouldn't be very interesting if [[CurbStompBattle they just stomped the baddies without even trying]], and [[DownerEnding it wouldn't be very satisfying if they lost]].

The problem with video games, though, is that the progress of the hero is directly tied to the skill of the player. And a player who's bad enough to start losing is probably bad enough to continue losing. [[CriticalExistenceFailure While video games rarely simulate the negative effect that injuries have on fighting prowess]], this still makes video game fights more similar to reality than the heroic mano-a-mano battles seen in movies.

The solution is to make characters more powerful when they're near death, to make the [[ComebackMechanic dramatic comeback]] a possibility. Hence the Desperation Attack, abilities or equipment that power up as the player character starts losing. Which, for most games, usually means when their health gets really low.

Occasionally, this leads to a situation where the best strategy is to run around on the edge of death for the massive bonuses it gives you.

Not to be confused with so-called "desperation moves" in {{Beat Em Up}}s, which are just special moves CastFromHitPoints, though these are sometimes replaced with Desperation Attacks when health runs low.

Related to the LimitBreak, which is frequently accessed by taking damage but does not strictly require the user to have critical HP before use. Can also be a SubTrope of a CriticalStatusBuff (or its enemy counterpart, TurnsRed; which in turn has a move-related subtrope, called LastDitchMove) as well as SituationalDamageAttack (if the attack gets more powerful the closer you are to death). Can also overlap with LastStand. Compare RubberBandAI.



[[folder: Action Adventure Games ]]

* ''VideoGame/AliceMadnessReturns'' has 'Hysteria Mode', which is activated when Alice's health is down to one rose. Time slows down and she is able to deal more damage to enemies. However, it only lasts for a short while.
* ''[[VideoGame/CastlevaniaChroniclesOfSorrow Castlevania: Aria of Sorrow]]'' has the Lubricant soul, which raises your stats as your health drops. It also has the helpful item spoilt milk, which drops your health to one.
* In ''TheIncredibleHulkUltimateDestruction'', when Hulk's main life bar is depleted, he enters Adrenaline Rush mode, which reveals the last of his life, increases his strength and gives him unlimited [[LimitBreak Critical Attacks]]. It's not easy to get or maintain an Adrenaline Rush as Hulk will [[HealingFactor regenerate]] to 75% of his main life bar when he's not getting hit and gets health from any enemy he defeats, meaning any situation that puts him into it will likely kill him before he can use a Critical Attack.
* In ''VideoGame/TheLegendOfZeldaTheMinishCap'' Link learns, in addition to his normal full-health SwordBeam, a beam attack that only works when his health is at or below 1 heart.
** One of the rings in ''VideoGame/TheLegendOfZeldaOracleGames'' also gives you this ability.
* ''VideoGame/{{Prototype}}'''s Adrenaline Surge ability grants Alex temporary invincibility and one [[LimitBreak Devastator]] use when he's nearly dead. Unsurprisingly, it's made by the same team as the Incredible Hulk.


[[folder: Action Games ]]

* One of the few things most ''VideoGame/DevilMayCry'' fans admit to liking about the otherwise [[FanonDisContinuity non-existent]] ''Devil May Cry 2'' was the Desperation Devil Trigger. When Dante's health was in the critical, activating his Devil Trigger SuperMode would cause Dante to shift into a towering alternate devil form with NighInvulnerability and dramatically improved power.
* In ''VideoGame/NinjaGaiden'', the Unlabored Flawlessness becomes the most powerful weapon in the game if your health is at critical levels.
** In ''Ninja Gaiden III'' and ''Sigma+'' on the UsefulNotes/PlaystationVita you get the option for "Hero Mode" which activates at 30% or less health and makes guarding and evading automatic, rendering death almost impossible, and last for a fairly long time.


[[folder: Fighting Games ]]

* ''VideoGame/ArtOfFighting'' introduced the Desperation Move, which can only be used when the player's health is under about 1/3rd. This was retained in future SNK {{Fighting Game}}s.
* ''Videogame/DeadOrAlive5'' has the Power Blow, a move that, if it connects, unleashes a cinematic combo and ends with you aiming where you want to launch your opponent, like into a stage hazard or [[FreeFloorFighting off an edge]]. What makes it a Desperation Attack is that it can only be used when you're below half health.
* In the ''VideoGame/DragonBallZBudokai'' games, there are several ability capsules you can equip that activate when your health drops below a certain point. Character-specific examples are Babidi's Mind Control for Vegeta (Turns into Majin Vegeta when health is at one bar or less) and Freeza's Space Ship for Freeza or Cooler's Space Ship for Cooler (Turns into Mecha Freeza or Metal Cooler respectively when health drops to zero). Other examples include Senzu Bean (Restores health to full when health drops to zero) and Senzu Bean 1/3 (Gives you an extra bar of health when health drops to zero).
** ''Dragon Ball Z: Hyper Dimension'' for the Super Famicom had actual desperation attacks for the characters, which could be used when the characters health dropped to a certain amount.
* In the doujin FightingGame ''VideoGame/EternalFighterZero'', each character has a unique "Final Memory" move, which is a level 3 super that is only accessible when the character is down to their last 1/3 health. These range from extremely damaging attacks to special effects like freezing time or granting hyper armor. In many cases, the attack models the {{canon}} scene [[{{Utsuge}} in which the character dies]], hence the name.
* ''VideoGame/FatalFury'' was also one of the first and most well-known uses of the trope.
* ''VideoGame/TheKingOfFighters'' had both the Desperation Move and the [[LimitBreak Super Move]]. If you had low life and a full super meter, you could perform [[BreadEggsBreadedEggs Super Desperation Move]].
** Later, this mechanic disappeared, so supers were Desperation Moves only in name. However, these returned in The King of Fighters 2002 and its Unlimited Match remake. In these games, a character's [=MAX2=]/Hidden Super Desperation Move can only be executed with 3 super bars and 35% health or less.
* Some minor SNK games (and certain Grooves in ''[[VideoGame/CapcomVsWhatever Capcom vs. SNK]]'') would allow the player to perform unlimited Supers if their health was critical.
* ''VideoGame/MagicalBattleArena'' combines this with the Super Mode mechanism. A few of these moves, however, inflict damage on the user, which is a bad thing since you have to be on your sixth and final bar of health in order to use the attack in the first place.
* In ''VideoGame/MarvelVsCapcom2'', if Jin was the last member alive on a team with less than 30% health left, he activates GoldenSuperMode upon standing on the ground. It takes two hits to stun him, his attacks are strengthened and specials augmented. However, if an opponent can keep him off the ground, he can't activate it.
** In ''VideoGame/MarvelVsCapcom3'', knocking out Phoenix with the super meter at [[MemeticMutation le-le-le-le-MAXIMUM]] fully heals her, turns her into Dark Phoenix, and provides her an enhanced moveset. This health is meant to be balanced, as: Phoenix and Dark Phoenix each have 420,000 hp (the lowest for any other character, including resident GlassCannon Akuma, is 800,000); the pair have pitiful defense; and Dark Phoenix's health drains constantly (though it alone can't knock her out). The two of them do have a Healing Field super, but it's very short-ranged and so either powerful or punishable.
** 3 introduces the [[TurnsRed X-Factor ability]], which is available to everyone on the cast, although the actual effect is unique to each character. It can be triggered at any time but is best used as a Desperation Attack because the fewer characters you have, the stronger and longer the effect.
* ''VideoGame/StreetFighterIV'' introduced the concept of "Ultras". The unique twist with these is that instead of directly being based on the amount of HP a player had, the game has a separate "Revenge" meter that filled up as the player took damage.
* NarutoShippudenUltimateNinjaStorm2: All characters have "Awakening Mode", whereupon they transform into their respective Kickass modes. To wit: Naruto-->[[SuperPoweredEvilSide 4 Tails form]], [[LethalJokeCharacter Tobi]]-->[[spoiler:"[[BigBad Mad]][[TheChessmaster ara]]"]]
* In ''VideoGame/Persona4Arena'', all characters enter "Awakening" mode upon breaking out of a combo with 35% of their health left or lower, granting increased defense, 50 SP, and a new SP attack, which is in arguably every case, their strongest attack. (outside of the [[AwesomeButImpractical Instant Kill]] moves.)
* ''VideoGame/SamuraiShodown 5'' had a mechanic called Mu no Kyouchi ("Circumstance of Nothing"), which caused the opponent to slow down and opened up a powerful attack, but which could only be accessed after one already lost a round and had lost a certain level of health. Also inverted with the game's [[FinishingMove finishing attacks]], which only worked if the opponent had already lost a round and a certain amount of health.
* In ''VideoGame/SuperSmashBros Brawl'', [[Franchise/{{Pokemon}} Lucario's]] attacks get more powerful as his damage percentage increases, peaking out at 168%. This is invoked in an event match where you have to play as Lucario starting out with high percent (182%).
** Related: If a character is down several points or stock, they automatically gain [[LimitBreak Final Smash]] powers the next time they drop down onto the stage.
* ''VideoGame/{{Tekken}} 6'' has "Rage Mode", which activates when a player is near death, making them much stronger.
** Also a case of TheComputerIsACheatingBastard, as in arcade mode, and most modes, in fact, when you fight Jin, at the start of every round he will ''begin'' in Rage Mode. Even worse, the true final boss gets an upgraded Rage Mode, where both attack ''and'' defense increase dramatically. And it's ''also'' activated at the beginning of the round.
** Rage Mode is more akin to a ComebackMechanic. It amps up your fighter's strength but does not give them any new attacks. However Rage in ''7'' HAS been elevated to a full-on DesperationAttack as it enables the use of "Rage Arts", powerful last-ditch moves the characters can only use when their lifebar is nearly depleted. However [[DeathOrGloryAttack you only have one shot]] at it: using the attack, hit or miss, will burn any opportunity to use it for the remainder of the current round.
* ''DoubleDragonNeon'': Once Giga Skullmageddon TurnsRed, he starts using his Cinematic FlashStep Combo of Doom, which is guaranteed to take off a life if you get caught in its [[CrosshairAware crosshairs]].
* Dropping to red health in ''Videogame/JojosBizarreAdventureAllStarBattle'' will put you into Rumbling Mode, where your attack increases, the Heat meter fills faster and a cool cut in of the character flashes. Certain characters instead get Preparedness Mode which grants Super Armor when not moving.
** Johnathan and Valentine have a Desperation Move ("My Final Harmon" and "Back From the Other Side!"), giving them more health, but [[PowerUpLetDown rids them of their heat gauge (and removes all currently held body parts for Valentine)]]. Kosaku's is a combination of this and ResetButton, granting him health, rewinding the clock back by 10 seconds, [[TheLastOfTheseIsNotLikeTheOthers makes Kars, Johnny, Pucchi, and Gionro's super modes null]], and [[ThisIsGoingToSuck granting Johnathan and Valentine back their heat gauge.]]
* ''VideoGame/PunchOut'' on the {{Wii}} gives [[FinalBoss Mr. Sandman]] a [[https://www.youtube.com/watch?v=imDTsu5TA90&feature=youtu.be&t=5m50s brutal desperation attack]] when he's on the cusp of losing the match. He roars with anger, huffs with exhaustion and wipes sweat between attacks, and surviving long enough to land a counter-attack is the ''only'' time the game gives you a free star... and landing that star punch will knock Mr. Sandman out.


[[folder: First Person Shooter ]]

* In ''Videogame/{{Borderlands 2}}'', Krieg has a skill called "Light the Fuse" that makes it so that when his health reaches zero, rather than being forced to his knees and hip-firing, he instead breaks out a bundle of dynamite and becomes a Suicide Psycho. In this state, he can freely run around and chase down enemies while tossing dynamite at them. When the timer runs out or if you trigger it, he'll then blow himself up. If he manages to score a kill, he'll earn a Second Wind and be back to normal (though killing enemies by suicide bombing them earns him a temporary speed boost).
** Most of the skills in his "Mania" skill tree is about dealing as much damage as he takes. His most powerful skill, "Release The Beast" lets him transform into a Badass Psycho when he's at 33% health.
* In ''VideoGame/TeamFortress2'', the Soldier's Equalizer is meant for this. Initially, it would not only increase in power the lower his health, but also allow him to run faster. Since the weapon has been split into two different weapons, one dedicated to each of the original's bonuses, the new Equalizer is now solely dedicated to this. On top of this, the weapon blocks healing from Medics (until the Gun Mettle update changed to 90% less healing), making it even more of a desperation attack. ''Finally'', as a last resort, the Equalizer reaches its ultimate in its desperation. As a last ditch effort, the Soldier can toss it away, then use one of his grenades to blow himself up, [[TakingYouWithMe along with any enemies and buildings within six feet of him.]]
* ''VideoGame/PAYDAY2'' has the Swan Song skill, which lets the user stay on their feet for a few seconds after losing all their health so they can either run away to safety so another player can revive them easier or take down as many cops as possible until they go down. Acing the skill not only extends the timer, but it also grants the player infinite ammo (as long as there's one bullet left in the current magazine) so that they can tear cops a new one (specific guns won't get infinite ammo this way for balance reasons).


[[folder: Hack And Slash ]]

* Both the ''VideoGame/DynastyWarriors'' and ''VideoGame/SamuraiWarriors'' games have Musou attacks, {{Limit Break}}s that build by attacking and getting hit. However, if your character is at red health, the Musou meter will fill up on its own over time and the attack will come in the form of a stronger version called a "True Musou".


[[folder: MMORP Gs ]]

* ''VideoGame/CityOfHeroes'' gave the Blaster archetype the inherent ability of Defiance, which raises their attack power as their health drops (as of the eleventh update, this is no longer true--Defiance in that form was widely considered to be useless at best, and actively detrimental at worst by encouraging stupid play--so it was retconned into a more widely useable form). Defenders also get a desperation power called Vigilance, which reduces the endurance cost of their powers as their teammates' health drops (and this is also generally considered quite useless, as it 'rewards' you for doing your job badly, so a good player is unlikely to ever see this benefit).
** Amusingly, Defiance was originally called "Desperation" during beta testing of the update it was added in, but the name was changed due to player complaints. Considering how useless the original version of it was, it remained known as Desperation amongst players until it was finally upgraded.
** Vigilance was better than Defiance, in that it's more practical to keep a mixed (or all-Defender) team at a specific percentage of health than a single GlassCannon, and most Defenders had more productive things to be doing with their powers in many situations than keeping teammates at full health. Unfortunately, a team competent and organized enough to take advantage of Vigilance didn't actually need it, so the concept remained mostly undeveloped.
* DungeonFighterOnline's Asura's have the Deadly Enticer skill. While the requirement doesn't specify that they must be at low health, they have to have taken a certain amount of hits, and the most practical application is to use it when caught in an opponents SpamAttack which is usually going to be lethal
* In ''VideoGame/GuildWars'', an elite Necromancer skill stole enough health from a target enemy to bring your own to 50%. Though double-edged (it could lower your health, and heal the enemy if used when you were above 50%), and originally intended as an "oh $(@#" skill, it was rarely used that way. The skill was used to destroy some otherwise very difficult bosses by pumping the Necromancer's max health as high as possible, having the Necro hurt themselves down to very low health, then hitting this skill to tear away a big chunk of a boss's health.
** ''VideoGame/GuildWars2'' has downed skills. If a player is brought to zero HP, they will fall on the ground, unable to move, and a second, smaller health bar will start ticking down while all the player can use is four relatively weak abilities. If the player manages to kill a mob with these, or fill the downed health bar to full, they will rise back on their feet with a portion of their regular HP refilled. However, if you get downed too fast four times in a row, then it's over for good and you have to respawn at a waypoint, or wait for another player to resurrect you.
* In ''VideoGame/TheLordOfTheRingsOnline'', the Warden class has a single skill that restores power, which is needed to execute skills. However, this skill can only be used when the Warden has less than half of its health remaining. This is an interesting case, since the Warden also has a few skills that heal itself. This means that as long as the Warden doesn't heal itself too much, it can find a balance between regaining health and regaining power, allowing them to stay in a fight where other classes would eventually run out of health or power. This technique, known on the forums as "[[CallAHitPointASmeerp morale-surfing]]", essentially comes down to relying on your Desperation Attack to keep you from dying, while slowly burning down your opponent.
* In ''VideoGame/RuneScape'', the full Dharok's armor set has the effect of increasing the maximum hit when all four parts (helm, platebody, platelets, greataxe) are worn and remaining life points are low. As this armor degrades if dropped on death, players will often enter safe minigames (where nothing is dropped on death), and intentionally reduce their health to near-zero in order to inflict massive damage and gain massive XP. A favorite trick of players who train combat with this armor is to get one's health extremely low, then activate a protection prayer to stop damage, keeping him or her locked in desperation mode.
* ''VideoGame/StarTrekOnline'' Has the ability "Go down Fighting" which allows the player to do more damage the lower their ship's hull condition is.
* ''VideoGame/WorldOfWarcraft'': The troll racial ability Berserk used to be stronger at low health.
** The Warlock class has a talent that increase the effect of their Drain Life spell when their health is below 30%.
** Many boss encounters are more dangerous at low health due to this.
*** Honorable mention goes for this quote: "So much unstable energy... but worth the risk to destroy you!"
** In a tactical sense, if a party is wiping with the boss at low health some players may use self-resurrection abilities just to get in a few extra seconds of damage.


[[folder: Platform Games ]]

* The Skeleton Pirate boss in ''VideoGame/BinaryBoy'' can only attack by shooting scripted cannonball sequences from the background. He begins with eight cannonballs that are easily dodged, but their number doubles with each successful hit on the shipwreck you need to destroy to win the battle. By the end of the battle, he'll fire about 60 of them.
* ''VideoGame/{{Iji}}'' has the Retribution technique. You can only activate it when Iji's health is 5 or below and you have all 8 basic weapons, plus it only works once per area/boss. Still, it comes in handy for when you ''really'' want to dish out the hurt. As a bonus, it's also an InvulnerableAttack.
* All the first 8 bosses of the ''VideoGame/MegaManX'' series starting from ''X2'' gain one on low health. These generally do a lot of damage to the player (Crush Crawfish's Bum Rush, Bamboo Pandamonium's Youdantotsu), or put him in an undesirable situation (Wheel Gator drills spikes into a wall, Blizzard Buffalo fires a FreezeRay).
** In ''X8'', all of the first 8 bosses' {{Desperation Attack}}s are also used by the first form of [[spoiler:Lumine]].
* Six of the first eight bosses in ''VideoGame/MegaMari'' have these. A notable one is Reimu's, which continually spawns high damaging yin yang orbs until defeat. The orbs (and most attacks for that matter) can [[KaizoTrap kill you even after the boss dies]] as well.


[[folder: Racing Games ]]

* The ''VideoGame/MarioKart'' games give the more powerful items to players lagging behind, like [[ClassicVideoGameScrewYous spiny shells]], [[InvincibilityPowerUp starmen]] and [[RocketRide bullet bills]], while those in the lead get weaker items like [[NitroBoost mushrooms]], green shells and [[BananaPeel banana peels]].


[[folder: Roguelikes ]]

* ''VideoGame/TheBindingOfIsaac'' has Whore of Babylon item which Eve starts with. When health drops to half a normal heart, the player turns into a demonic form with greatly increased damage which lasts as long as the player exits the room with half a normal heart. One strategy is to get an item which slowly refills soul hearts and use a Blood Bank to get down to half a normal heart to keep this ability going. This item is not a desperation attack for one of the unlockable characters, though: when he picks it up, the effect is permanent.


[[folder: Real Time Strategy ]]

* In ''VideoGame/LeagueOfLegends'', there are several champions who get their stats boosted as they take damage. Olaf gains attack speed, Tryndamere gains bonus damage, and Aatrox heals himself more. Poppy's innate ability will typically cause her to take less damage the lower her health is. There is also an item called Maw of Malmortius that gives more attack damage the lower your health is. In fact, Maw is only cost-efficient when you you are low on health, stat-wise.
* ''Star Wars: Empire at War'' and its expansion have, for some units, the ability to self-destruct. The TIE Mauler was the only one to have this in the first game, and considering how pathetically weak its armour is, the self-destruct became useless unless the player managed to park ten of them at full health in the middle of an enemy formation first, just to ensure that at least ONE did some damage. The expansion gives this ability to the following Zann Consortium units: MZ-8 Pulse Cannon tank, Vengeance-Class Frigate, Aggressor-Class Destroyer. Much more effective for them since a. It's automatic and b. those units could actually survive long enough after taking a shitload of damage for the ability to be effective.
* In the ''VideoGame/{{Warcraft}} 3'' map ''DefenseOfTheAncients'' (later remade as ''VideoGame/{{Dota 2}}''), Terrorblade the Soul Keeper has the Sunder move that swaps his health percentage with a target's, naturally becoming stronger as he gets weaker.
** Huskar the Sacred Warrior has Berserker's Blood, which increases his magic resistance and attack speed as he takes damage, but only increases in power down to 10% health.
*** Huskar is basically DesperationAttack: The Hero, as his Inner Vitality skill grants regeneration to any ally that increses if they're below a certain health threshold, and his other abilities are CastFromHitPoints.
** Abaddon the Lord of Avernus has a variant in his Borrowed Time move, which turns any damage taken into healing while active, and can auto-activate if he drops below 400 hp and it's available.


[[folder: Role Playing Games ]]

* ''BreathOfFire'' has your characters attack faster when their health points are dwindling.
* The Crisis Arm, one of Robo's final weapons from ''VideoGame/ChronoTrigger'', claims to work this way, but actually depends on the last digit of your HP. There are actual desperation attacks in the form of Frog's "Frog Squash" tech and Ayla's "Dino Tail" tech.
** Then, there's the CombinationAttack Grand Dream, which is a massive, impressive ''three-character'' Desperation Attack. It's surprisingly effective against the final boss, simply because he has a habit of near-flattening you. Grand Dream contains Frog Squash as one of its components.
** The similarly insane Frog Flare (a Combination Attack of Frog Squash and Lucca's * Flare) is universally acknowledged to be ''the'' best way to take out the final form of Spekkio, who uses [[HPToOne Hallation]] a lot - particularly if you're playing the DS version and got the GameBreaker armor for Lucca, which renders Hallation Spekkio's only attack capable of damaging her - and you're never going to die from HPToOne attacks.
* ''VideoGame/DarkSouls'':
** The Tearstone Rings from ''VideoGame/DarkSouls'' increases your damage (Red) or defense (Blue) when you are near death. It is common for GlassCannon builds to pump their health to 1 via Power Within pyromancy (which also increases your damage) and land a OneHitKill onto their opponent.
** By the time of ''VideoGame/DarkSoulsIII'', the Morian Blade, which has the same effect as Red Tearstone Ring, actually can stack with Red Tearstone Stone's damage boost, combining with the fact the Morian Blade can be used as offhand weapon and it still boosts other weapons and spells, it results in what essentially can be described as wearing ''[[UpToEleven two]]'' Red Tearstone Rings at once, effectively delivering more OneHitKill than before.
* [[TroubledButCute Fenris]] from ''VideoGame/DragonAgeII'' has the Veneer of Calm ability, allowing him to do increased damage as his health drops.
** This ability is also on the Ravager talent tree somewhere.
* The Hexer's Revenge ability in ''VideoGame/EtrianOdyssey'' is straight defense-ignoring damage based on how little HP the Hexer has remaining. It was toned ''up'' and made even more powerful in the sequel.
** In ''VideoGame/EtrianOdissey3'', the Yggdroid has the "HP Cannon" attack, which deals the difference between its maximum and current HP. And it helpfully has a passive ability which damages it each turn in exchange for a boost in attack power, which never kills it and instead leaves it with at least 1 HP.
* The ''VideoGame/{{Fallout}}'' series of games have a few perks that reflect this ability, such as Adrenaline Rush (raising your strength if you drop below 50% hp), Die Hard (raising resistances to damage when you drop below 25% hp), and Nerd Rage! (increasing your strength to maximum if you dropped below 25% hit points--and requiring a certain amount of Science skill).
** Unfortunately, by that stage of any of the games, your character was likely to be wearing items boosting strength to 10 (absolute maximum, no temporary bumps over it allowed), or 8-9 if the starting build was really puny. Add to that the fact that the most successful melee and unarmed builds only required and effectively used medium strength scores, and it really seems pointless (melee and unarmed being the only usable attacks utilizing strength score bonuses, only other uses of strength were max carry weight and min score to wield weapon, as well as the really rare and optional quest and the absolutely buggy and random throw skill). Also, unlike Dungeons&Dragons, strength bonuses were small and rather linear, with the average weapon in the second half of a game dealing 10 or 20 times more base damage than the strength bonus. Furthermore, since enemies were plentiful and came in groups, which were defeated by a combination of strategy and predictable/expected critical hits, these strength bonuses really meant nothing whatsoever. A temporary increase in carry weight, only in the heat of battle and at the brink of death, also obviously provided little benefit in a world without encumbrance-increasing magic.
* One of these shows up in many of the ''Franchise/FinalFantasy'' games.
** ''VideoGame/FinalFantasyV'', has a [[PowerCopying Blue Magic]] spell called [[MyNameIsQuestionMarks ???]] (which actually has ''no'' [[CallingYourAttacks call box]]). It does damage equal to the difference between the user's max HP and current HP. Therefore, using it when you're at critical HP will do damage almost equal to your max HP. It shows up in many other Final Fantasy games after V, as a Blue Magic spell, either named "???" or "Revenge/Revenger/Revenge Blast". However, it's a bit of a UselessUsefulSpell, as enemies who have the move tend to have [[HealthDamageAsymmetry max HP many times higher than what you ever get]], making it a potential OneHitKill in their hands.
** ''VideoGame/FinalFantasyVI'' introduced actual Desperation Attacks to the series, incredibly powerful attacks that can randomly occur when a character with critically low HP is given the "Fight" command. However, they have only a one in sixteen chance of occurring, meaning most players don't ever see one. There is also the Valiant Knife, whose power increases as the wielder's HP decreases, making it the opposite of the Ultima Weapon, which gets stronger the ''more'' health one has.
** ''VideoGame/FinalFantasyVII'' has the ''[[ExactlyWhatItSaysOnTheTin Final Attack]]'' materia, with which almost every spell materia can be paired. Equipping it on someone lets that character [[TakingYouWithMe cast one last spell upon their demise]], but the right combination can bestow functional immortality. [[spoiler: Phoenix]] is recommended.
** ''VideoGame/FinalFantasyVIII'''s Limit Breaks. The availability of the Limit Breaks is predicated on how much HP there is left ''proportional to your total HP'', so if your health stats were high, which is easy to accomplish even early in the game with proper junctioning, you'd still be able to access your Limit Breaks with a reasonable number of HP. The game lets you know exactly when you can use them by turning the stat display yellow, and you can reset the ''Attack'' option an unlimited number of times per turn with the circle button until it gives you the option to use your Limit. This feature makes them your ''primary'' mode of attack, not a desperation attack, and all but renders them {{Gamebreaker}}s.
** ''VideoGame/FinalFantasyIX'' has Steiner's Revenge ability, as well as his Charge!, which causes every other party member at low HP to use their normal attack without using up their turn.
*** And the Blue Magic Limit Glove, an otherwise unremarkable spell which is guaranteed to do 9999 damage if (and only if) Quina has exactly 1 HP left when using it. Mostly useless because of this limitation, but with proper element cancellation...
*** The standard strategy is to give him/her Auto-Revive, and then let something kill him/her - which brings him/her back on 1 HP. Failing that, Phoenix Downs are close to useless for all other purposes, because they only provide single-digit HP; however, that means there's a one in nine chance...
*** A lot riskier and more luck-based, but if [[spoiler: one of Necron, the final boss's, attacks reduces one character to 1 HP. However, that both requires Quina to be the target, as well as Necron not launching a follow-up attack that does any measure of damage to Quina]].
*** Savvy players will knock Quina out in a battle, then go to a save point and revive him/her repeatedly (resetting each time) until s/he has 1 HP. Perfect for taking out that tricky boss in one shot! It's also available extremely early (from the [[DiscOneNuke moment you get Quina]], in fact), letting you lay the smackdown on the rest of disc 1 and most of disc 2 (by disc 3 more reliable means of violence become available). By extension, it's also a valuable skill to have when doing the [[SpeedRun Excalibur II challenge]].
** ''VideoGame/FinalFantasyX'' has Auron's InfinityPlusOneSword, which does more damage as his health gets lower.
** Several items in ''VideoGame/FinalFantasyXI'', such as the Sorcerer's Ring or the Rasetsu armor set, have effects that only activate when the wearer's HP drops below a certain percentage.
** ''VideoGame/FinalFantasyTactics'' has the Meatbone Slash Reaction Ability, which deals your max HP in damage when your HP is critically low. It also has several other Reaction Abilities that function on the "Critical HP" principle, usually bestowing healing or auto-life effects. Finally, there are several attacks that utilize differences in your HP or MP to do damage.
** ''VideoGame/FinalFantasyTacticsAdvance'' has several "Last" abilities that cast a specific spell on the character at low health, such as Berserk.
** In addition, several of the games have skills that do a set amount of damage equal to a character's maximum HP minus their current HP.
** In a diversion from the usual LimitBreak method of dealing with this for the series, ''VideoGame/FinalFantasyXII'' allows you to combo attack much more frequently the lower your health. One of the best methods for dealing with most of the BonusBoss's uses this to its advantage by berserking 2 of your characters in critical health while using the third as a decoy. There are also unlockable options on the Licence grid that increase your Strength, Defence and Magic stats when HP Critical.
** ''VideoGame/FinalFantasyTacticsA2'' has the Blue Magic spell Cornered/Limit Glove, mostly used by Rockbeasts, which does [[{{Cap}} 999]] damage if the user has single-digit HP. Auto-revive is needed to learn it, since one must survive the hit. Amusingly, the AI will try to use the attack once they reach critical HP, even if their health is still too high for the attack to have any effect.
** ''VideoGame/DissidiaFinalFantasy'' has a variant of this with the Cosmos Judgment rules. When a player is in danger of dying in one more hit, their EX Gauge will instantly max out, giving them a chance to turn things around.
*** There's also the equippable support ability 'Back to the Wall' (which increases the player character's critical hit rate when their HP is in the red). 'Cat Nip' (which increases the player character's critical hit rate when they're at risk of losing in one HP attack) can often count as this as well, but the nature of the battle system means that the attacker can potentially [[OneHitKill win with one HP attack regardless]], assuming their BRV gets high enough to allow this.
* ''Franchise/KingdomHearts'':
** [[VideoGame/KingdomHeartsI The original game]] and [[VideoGame/KingdomHeartsChainOfMemories mid]][[UpdatedRerelease quel]] have the ability Berserk, which does indeed increase attack at critical health levels (the latter game and its remake requiring the use of the Hades enemy card).
** ''[[VideoGame/KingdomHearts358DaysOver2 358/2 Days]]'' has the [[LimitBreak Limit Breaks]], which can only be activated once your HP falls to 25% (50% with the right panel equipped). However, the threshold keeps getting smaller with each use, making each Limit Break riskier than the last.
*** All the same, as they can create a nearly minute-long attack that can deal upwards of hundreds of times your normal damage output, they will often be your method of choice for dispatching tough enemies. That said, the effects--and therefore the effectiveness--differ from character-to-character. Some have to charge, some just go berserk, some hit in a radius around them whereas others only strike forward, some are granted temporary invincibility, some are frozen in place, etc.
* Atton Rand from ''KnightsOfTheOldRepublic II'' has "Fighting Spirit," which causes his saving throws to increase as he takes more damage.
* ''[[VideoGame/ManaKhemiaAlchemistsOfAlRevis Mana Khemia]]'''s version of [[CuteGhostGirl Pamela]] has a skill called "No Bullying" which gets stronger as her health decreases. Unusually, her [[IntangibleMan immunity to physical attacks]] makes it easy and fairly safe for the player to power this up by using one of her high level CastFromHitPoints skills first.
* In ''VideoGame/MarioAndLuigiBowsersInsideStory'', Bowser may become afflicted with "Fury" (which causes him to dish out and receive more damage) if he is weakened enough.
* In ''VideoGame/MarioAndLuigiPaperJam'', if you take out one of the Koopalings in their [[DualBoss duo battles]] (Roy and Wendy or Larry and Ludwig), the surviving one will start attacking with a ''very'' powerful magic blast attack (which is pretty easy to counter and deals a hefty amount of damage to said Koopaling). Somewhat justified, as defeating their companions removes the battle gimmick (Wendy attacking Roy if you counter his giant rock attack onto her, or Ludwig and Larry using battle cards).
* The Muramasa Blade in ''VideoGame/MegaManBattleNetwork'' deals damage equal to how much HP you don't have. It caps off at 999, or 500 in later games.
** The Dark Cannon dark chip in ''Battle Network 4'' did damage equal to the amount of HP you lost as well, capping at 999.
** If you haven't already used quite a few dark chips, you're only able to use them when you're taking a hammering, albeit [[PowerAtAPrice at the cost of losing 1 maximum HP permanently for every battle you used them]].
* ''VideoGame/PaperMario'' has a couple badges that only kick in when Mario is down to 5 HP or less, such as Power Rush, which boosts Mario's attack power by 2. Then there's Mega Rush, which boosts Mario's attack power by 4 (increased to 5 in the sequel) but only when Mario has exactly 1 HP left. ''VideoGame/PaperMarioTheThousandYearDoor'' also allows you to obtain and equip multiple Power Rush badges to stack their effects, although damage is capped at 99 per hit.
* The ''Franchise/{{Pokemon}}'' games have several of these:
** Flail and Reversal are moves that get stronger the weaker the user is. When the user's HP are at less than 4% of maximum, these moves do the most damage.
** Pain Split divides your current HP and your enemy's current HP evenly between you; the more HP than you your opponent has, the better.
** Endeavor lowers the enemy's current HP to match your own.
** The moves Eruption and Water Spout are inversions: they get stronger the more HP the user has.
** The Guts ability dramatically increases strength if the user has a status ailment, whereas the Marvel Scale ability improves defense under the same circumstances. A bit more specifically, the Tangled Feet ability doubles evasiveness if the user is confused.
*** Quick Feet is Guts/Marvel Scale for speed.
*** Facade is Guts turned into a move.
** Overheat, Psycho Boost, Draco Meteor, and Leaf Storm sharply reduce the user's Special Attack level, making them less and less powerful the more times they are used. Superpower and Close Combat are variations of this; they are slightly less powerful, but lower the user's Physical Defense as well as another stat (Physical Attack for Superpower, Special Defense for Close Combat).
*** The Ability Contrary then inverts this trope: rather than these moves becoming less powerful the more they are used, they will actually buff you instead, becoming stronger with use.
** Struggle is an EmergencyWeapon (and CastFromHitPoints at that), as it only executes when the Pokémon has run out of normal combat moves. It also comes into play if the opponent's Pokémon has used Encore, which blocks the player's Pokémon from using any moves other than the one it last used, and that move is out of PP. It is completely exempt from the usual ElementalRockPaperScissors.
* ''VideoGame/TalesOfPhantasia'' gives Cless one when he equips a certain title.
* ''VideoGame/TalesOfSymphonia'' has the Over Limit form, which cuts damage in half and makes the character ImmuneToFlinching. It activates when a character's invisible Tension gauge is filled, which can be done in many ways, but the most common way is taking a lot of damage. Unfortunately for the player, boss enemies can go into Over Limit, too!
** Also, some characters have {{Limit Break}}s that can only be used in Over Limit mode, and a few of them also require the character to be at low heath. Lloyd's Falcon Crest, for instance, can only be used when his health is at 16% or less. Presea's Crimson Devastation, from the UpdatedRerelease, is even worse. Not only does it require Presea's health to be low, every other party member must also be [=KO'd=]. And even then, whether or not the move activates is random. To balance it out, Crimson Devastation is by far the strongest attack in the game, capable of cutting the health of even the toughest BonusBoss ''in half''.
* ''VideoGame/WildArms3'' has Valiant, a spell that adds the difference between the recipient's current and max HP to their attack power.
* A number of clothes in ''VideoGame/TheWorldEndsWithYou'' have abilities called "SOS", which only trigger when the player is in "mortal peril" (their health bar is completely off one screen and less than half is left on the other).
** Later in the story you can use the Lapin Angelique Suicide Special (LASS) strategy, which puts you in mortal peril at the start of battle. As the name suggests, all the gear you need is from the Lapin Angelique line, which tends to be oriented towards this trope anyways.
* ''VideoGame/{{Xenogears}}'' has an equippable item which increases your attack power ridiculously when near death. If you give it to Fei, he can do 19998 damage every turn when not inside his Gear... and being outside his gear means most of the time gear-sized enemies miss him. He becomes a gear-destroying machine.
** There's a similar accessory in the SpiritualSuccessor VideoGame/{{Xenosaga}} Episode 1 called the Bravesoul. It increases the equipped character's attack power as their health falls, leading to noticeable bonuses at half health, and a situation reminiscent of a ''VideoGame/FinalFantasyVIII'' LimitBreak-fest at critical health.
* The Jew class in ''VideoGame/SouthParkTheStickOfTruth'' deals more damage as health drops. Naturally, Kyle is of that class.
* In ''VideoGame/{{Undertale}}'', Papyrus will skip right to his final attack of his HP is low enough.
** During the last fight against Mettaton, the Pose action boosts ratings by a greater amount when the protagonist's HP is low.


[[folder: Shoot Em Ups ]]

* ''VideoGame/NoMoreHeroes'' has at least one desperation attack for most bosses. Some bosses, mainly in the first game, gained a OneHitKO when they were down to about half health.
* In [[VideoGame/{{Touhou}} Subterranean Animism]], the game throws a full powerup at you to boost your shot power to maximum as soon as you're on your last life.


[[folder: Tabletop Games ]]

* ''MagicTheGathering'' has the ''Fateful Hour'' mechanic introduced in the [[DarkestHour Dark Ascension]] block, in which some cards become better when your Life is 5 or less. Mind you, it's a game where the adage is [[CriticalExistenceFailure "it's OK if you have 1 Life, as long as your opponent has zero"]].
** The card [[http://gatherer.wizards.com/Pages/Card/Details.aspx?multiverseid=193467 Near-Death Experience]] causes you to instantly win the game if you have exactly 1 life on your upkeep.
** [[http://gatherer.wizards.com/Pages/Card/Details.aspx?multiverseid=80246 Soulbast]], from Kamigawa, takes the same general idea behind [[http://gatherer.wizards.com/Pages/Card/Details.aspx?multiverseid=262871 Fling]] and applies it to every creature you control, which has the unfortunate side effect of leaving you defenseless against other creatures.


[[folder: Turn Based Strategy ]]

* ''VideoGame/{{Disgaea 2|CursedMemories}}'' is rife with this, some characters getting random 1-Hit-Kills, Double Attacks, or stat boosts at 25% health. To help with this, you can equip an accessory that limits your HP to 25%.
* ''FireEmblem 9'' and 10 have several abilities that improve stats when health is below a certain amount or percentage, usually only available to player characters and bosses.
** In a similar vein, ''Fire Emblem'' 4 has the skills "Wrath" and "Ambush", which activate when a character drops below 50% health, giving automatic critical hits and first strike, respectively. And "Prayer," which activates in the low single digits and greatly increased evasion.
** ''VideoGame/FireEmblemAwakening'' brings back Wrath (nerfed to +20% critical chance at half health) and Ambush (now Vantage).
* In the ''VideoGame/SuperRobotWars'' games, this happens if a pilot has the "Prevail" skill. Once a certain percentage of their HP has been depleted, they gain major stat boosts.
* In any ''VideoGame/TotalWar'' game, if a unit breaks and is unable to flee, it goes into "Fight to the Death" mood, boosting the unit's attack.


[[folder: Wrestling Games ]]

* When your momentum gauge flatlines in ''Wrestling/{{WWE}} Day of Reckoning 2'', you gain access to a powerful Momentum Shift attack, which swaps your and your target's momentum gauges.
* In ''[[VideoGame/{{WWE}} WWE '12]]'' a character can have the "Comeback" ability. This allows a severely damaged character to get up and/or launch a flurry of attacks in a [[PressXToNotDie quick-time event]] which leaves the character's momentum gauge full and their opponent dazed, ready for a FinishingMove.


!!Non-video game examples:

[[folder: Fan Fic ]]

* In the climax of the Leviathan arc of [[FanFic/WeaverNine Weaver Nine]], Leviathan pulls out several new tricks as the fighting worsens for him, and his final attack- a massive open portal to the source of his water -creates a wave that ''reaches above the clouds''.
* The [[ZergRush "Last Resort Robo-Launcher"]] from ''Fanfic/CalvinAndHobbesTheSeries''.


[[folder: Film ]]

* Death Blossom, an aptly named, cinematically ''gorgeous'' and single-use MacrossMissileMassacre close-range attack performed by ''Film/TheLastStarfighter'' against an armada of space fighters.


[[folder: Literature ]]

* In Literature/TheArtOfWar, Sun Tzu warns against a combination of this and LastStand. "Throw the troops into a position from which there is no escape, and even when faced with death they will not flee." In actuality, Sun Tzu was warning against this because desperation attacks can still be pretty effective even if the enemy dies while doing it; that is, if someone dies but takes out a decent chunk of your infantry while doing so, they've still won since you need time and man power to replenish and must potentially stop your forward progress. His answer was to always leave an escape route for the enemy, thus allowing them to rout, making them easy targets... and allowing them to run into the ambush you set up on the escape route so you could take them out there.
** In modern amphibious assaults, this was one reason for their success. The attacking soldiers have nowhere else to go and so they have no choice but attack directly.


[[folder: Tabletop Games ]]

* ''TabletopGame/{{Exalted}}'': a number of Malfeas Charms actually become nastier as your wound penalty increases, such as the Parry DV penalty reducer, which starts providing more bonuses as you take more injuries (that don't cause penalties because FeelNoPain is a major part of the Malfeas charmset). The most impressive, however, has to be Driven Beyond Death, which allows you to respond to being ''killed'' by going full-on OneWingedAngel.
* The second version of Prince Vladmir Tzepesci in {{TabletopGame/Iron Kingdoms}}' has Might of Kings, gaining a stat bonus the lower his health gets.


[[folder: Real Life ]]

* An adrenaline rush is the body's way of invoking this. When the brain releases enough adrenaline, a person's muscles work harder, and any pain will temporarily numb. However, this also comes with an increased heart rate and faster breathing, and going for too long at high intensity can result in a HeroicRROD when the adrenaline wears off.
* The very name of the "last ditch effort" refers to a desperation attack. In the Vaubanesque era, most fortifications consisted of subsequent sets of ramparts and ditches. The last ditch was the innermost ditch before the citadel. A last ditch effort would be an all-out sally directly from the citadel with all available forces, which would decide the battle in either way.
* When the battle became desperate for [[ImperialJapan Japanese]] fighters in WWII, [[HonorBeforeReason rather than surrender]], [[SuicideAttack they would fly their own planes]] into opposing [[TheAlliance Allied]] ships.
* The Banzai charges were the same, but on foot.
* RammingAlwaysWorks is basically this trope in RealLife.
* In sports where points are gained by scoring goals, a team that only needs one goal late (generally [[UsefulNotes/AssociationFootball Football]] variations) in the game will send their goalkeeper to attack especially from corners. It's very risky as it leaves an open goal but when it works, it works well. The FIFA games in particular have implemented this behaviour for since '08. DownToTheLastPlay has more examples of when this comes off.
** A less extreme but still risky version of this is if a team has a tall defender, they will often be sent to play up front of the attack as a target man. The team will attempt to punt, cross or lob the ball in a way that the defender can score a headed goal or knock the ball down to a team-mate. An example of the tactic is that Manchester United would often send their central defender Nemanja Vidic up front if they are down towards the end of the game.
*** An inversion of this tactic is when a team's attack has tall forwards who play the entire game as 'target men'. This is generally called the "long ball" tactic and considered to be a lower skilled and non-technical style that is often utilised by teams of inferior skill to others. It is often utilised in lower divisions where fast and technically skilled players are rare but physically strong and tall players are common.
* IceHockey has the tactic of 'pulling' the Goalie, where the goalie leaves the rink and is replaced by a non-goalkeeper. The few occasions that a Goalkeeper has scored in the NHL, it was as a result of the other team pulling their goalkeeper and leaving an empty net. It has also led to a handful of embarrassing own goals by misplaced passes or a player being unaware the goalkeeper wasn't going to be there to receive the pass. It's statistically a goal-losing proposition (in the NHL, empty-net situations with a one-goal difference at the end of a game on average sees the team in the lead score a goal about 1/3 of the time and the team behind score just 1/9 of the time), but regardless of the margin of victory a loss is a loss.
* There is a inversion in Australian Rules Football. At the end of a match where a team is down by a few points, if they receive a mark or free kick both teams will 'flood' their entire team towards the goal area. The inversion is that it's not the attacking team which causes this, but the defending team who seek to cause as much disruption as possible to any attempt to catch the ball which can result in a free kick at goal. If the defending team does not flood back, it is better for the attacking team who would prefer the open space for their attackers to use to run onto a ball or jump to catch it. When they do, the attacking team has nothing to do but send all their players forward to try to counter the numbers of defenders. It is a desperation ''defense'' which the other team will then turn into a Desperation Attack.
* In a sort of meta-example, there is [[http://www.youtube.com/watch?v=pS5peqApgUA this famous comeback video]] of a ''Street Fighter III'' match between two high-ranked players. The comeback was not the result of a desperation attack, but by the skillful application of another game mechanic built into the game in the context of a situation which would have called for a desperation attack had one been implemented into the game.
** To elaborate on the feat: Daigo Umehara (playing Ken) was reduced to 1% health. Any damage at all, even chip damage, would have caused him a KO. Justin Wong (playing Chun Li) decides to show off by using the "Houyoku Sen" Super Art, thinking it would close the distance and trap Daigo completely. Daigo then proceeds to Parry each and every single hit before dealing out a devastating combo of his own. [[NiceJobBreakingItHero Also a rather unforgettable case of handing the match to one's opponent because of trying to be fancy in front of a crowd rather than play it safe]].
* In gridiron football, the quarter does not end until the clock expires AND the ball is dead. Therefore, it is always possible to score a touchdown on a single play. With seconds remaining in the 4th quarter, a team down by a 4-8 points (or by 1-3 but out of field goal range) will execute one of two plays to try to score in one play: the Hail Mary Pass, which calls for five wide receivers breaking for the endzone while the quarterback throws up a jump ball, or the Hook and Lateral, wherein the quarterback throws a short to medium range pass, and then the offense attempts to cobble together broken field runs and lateral passes to keep the play alive until they score. Also, since the half cannot end on a defensive foul, if the defense commits a penalty on such a play, the yardage is applied and the offense gets a free play. A defensive pass interference on a Hail Mary Pass gives the offense one play from the 1-yard line.
** Another desperation play in the onside kick, in which the team kicking off attempts to recover the ball after it has traveled ten yards down field or been touched by an opposing player. Usually, it's used when the kicking team is trailing without sufficient time to get the ball back by playing defense, but it's also occasionally used as a trick play at the start of a half. It has about a 10% success rate, in part because the receiving team is usually expecting it and in part because [[{{We Win Because You Did Not}} the receiving team doesn't actually have to recover it- they just need to prevent the kicking team from recovering it]] -- if the ball goes out of bounds or is touched first by the kicking team within ten yards of the kick, the ball goes over to the receiving team. (Unexpected onside kicks do have higher success rates, though the rate goes up to about 33% and a team doing it too often makes it no longer unexpected.)
* The famous Scott Smith/Pete Sell fight in the UFC featured Smith taking a direct hit to the liver which, for those who don't know, basically puts you on a very short timer before temporary paralysis sets in. While Sell moved in for an entirely-unnecessary follow-up, Smith threw one last punch. Sell, naturally, thought he'd already won, so he'd dropped his defence. [[http://www.fightreport.net/wp-content/uploads/2006/11/scott-smith_pete-sell.gif Then this happened.]] Smith's not faking there; immediately after that moment he collapsed too.
* In basketball, a missed final free throw on shooting and floor fouls is live, so a team down by 2-3 with one free throw remaining and only a few seconds left on the clock will attempt to miss the free throw and recover the rebound for a chance at a field goal to tie the game. This has a success rate similar to onside kicks in gridiron football.
* Baseball imposes no restriction on defensive formations beyond needing to have a pitcher on the mound and a catcher behind home plate. Thus, on rare occasions where the winning run is on third with fewer than two outs, the center fielder may come all the way in to second base to serve as an extra infielder, since a fly ball to the outfield will mean the batting team wins whether or not it's caught (either as a base hit or as a sacrifice fly).
