->''"Come. Join me. Be part of my power."''
-->-- '''Makuta''' (absorbing [[BrainsAndBrawn Nidhiki and Krekka]]), ''Toys/{{Bionicle}} 2: Legends of Metru Nui''

The heroes are fighting a near-immortal BigBad and his [[TheDragon second-in-command]]. Both of them appear to run on some sort of "life force" or have several lives... the only thing for the heroes to do is keep fighting to wear them down, hoping to get them down to nothing. Slowly, the villains realize the tables have turned, and they're losing...

So the BigBad gives his life force a little boost by draining his companion to death.

Usually, the two villains [[VillainousFriendship get on very well and trust each other before this moment]], just for that little extra KickTheDog punch. Sometimes a particularly dedicated minion will even offer his life up voluntarily, but typically without any reluctance to accept it on the BigBad's part.

This is a sister trope to VillainOverride. See also JustDesserts. Contrast BequeathedPower, which is a HeroicSacrifice performed by "feeding" yourself to an ally.

'''As this is a betrayal trope and frequently ends in death, beware of spoilers.'''



[[folder:Anime & Manga]]
* In ''Manga/FullmetalAlchemist'', [[spoiler:Gluttony]] is devoured for this purpose. [[spoiler:Kimbley]] later succumbs to the same fate. However, the second victim ends up [[AssimilationBackfire biting the devourer in the ass]] later on. [[spoiler:Pride]] assumed that nobody could retain their sanity after being absorbed into him, but overlooked the fact that [[spoiler:Kimbley]] was [[InsanityImmunity already insane]] and [[CrazyAwesome loving it]].
-->[[spoiler:'''Kimbley''']]: These cries of agony are like lullabies to my ears!
* ''Franchise/{{Digimon}}''
** In ''Anime/DigimonAdventure'', [=VenomVamdemon=] eats his subordinate [=PicoDevimon=] for a marginal powerup during his ChewingTheScenery sequence. And he doesn't stop there, either, ultimately absorbing ''all'' of his surviving minions.
** Devimon also absorbed TheDragon Ogremon by turning him into Black Gears and absorbing him. In an unusual instance, Ogremon actually survived because he was blasted out of Devimon after trying to attack Angemon.
** In ''Manga/DigimonVTamer01'', Neo Saiba has [[EldritchAbomination Arkadimon]] delete and absorb the data of the partner Digimon of his allies in Alias III, [[spoiler:although by then, they've already [[HeelFaceTurn turned against him and joined up with Taichi]]]].
** Also, in ''Anime/DigimonFrontier'', [[spoiler:Lucemon does this to Crusadermon and Dynasmon shortly after their defeat by the Digidestined.]]
** Happens ''all the time'' in ''Anime/DigimonXrosWars'' due to the villains having the ability to Digi Xros with their underlings, whether the poor Digimon want to or not.
*** An interesting subversion is when [[spoiler: [=DarkKnightmon=] tries to forcibly fuse his superieor, [[BigBad Bagramon]] into himself, in order to gain full power. He actually succeeds...for about one second before Bagramon reverses the Digi Xros from within, becoming the devour]].
* In ''{{Anime/Shinzo}}'', the {{Mons}} that have replaced humanity turn into cards after being defeated, and they can power up by assimilating another Enterran's card. One villainess, a general in the BigBad's army, killed five of her peers well before fighting the heroes and used them to achieve a OneWingedAngel form.
* Fall absorbs Deuce's magical power (killing her) in her final fight in ''Manga/{{Nora}}: The Last Chronicle of Devildom''. This holds something of an inverted HeroicSacrifice because Deuce throws herself in front of Nora's spell to protect Fall, then apologizes for her weakness as Fall absorbs her afterwards.
* ''Manga/InuYasha'':
** Hiten eats his younger brother Manten (more specifically he eats the shards of the Shikon jewel implanted in his brother's head) after he's killed. Also a subversion, as he genuinely cares for his brother, and is using the strength to avenge him.
** In an anime filler arc, the leader of a tribe of panther demons does this to some of his subordinates when he realizes he is losing. Made worse since his tribe spent most of the arc gathering the shards to ''revive'' him after Inuyasha's father killed him in the past. The panthers give up the fight after their leader is defeated realizing he wasn't worth avenging.
* Szayel Aporro Granz from ''{{Manga/Bleach}}'' has specifically designed minions which he can eat to heal himself. In the manga, he actually ''eats'' the minion, but in the anime he turns it into a purple orb and then eats it.
** Giselle of the Sternritter injected her blood into Bambi, converting her into a powerful zombie. After Giselle's near death she drank the blood out of a pleading Bambi to restore her own health.
** When Yhwach infiltrates the Palace and his elite guard is killed he absorbs the energy of every Sternritter [[YouHaveOutlivedYourUsefulness not directly assisting him]] and uses it to revive his guards. After gaining full mastery of his powers and draining Ichigo, Yhwach repeats this on all the remaining Quincy save Uryu.
* In ''Manga/{{X 1999}}'' the TV series, after Fuuma has had his arm and half his face blown off, he orders Nataku to liquify and became a human skin graft, restoring himself for the final battle at the cost of his last henchman's life.
* ''Anime/TengenToppaGurrenLagann'' does this in a very strange, but very awesome way in the final episode. [[spoiler: Lordgenome, the [[HeelFaceTurn reformed]] BigBad of the previous arc, absorbs the Anti-Spiral's ultimate attack, converts it into energy, and allows the heroes to devour him for a power-up.]]
* In TheStinger of ''Anime/KillLaKill'''s episode 23, BigBad Ragyo absorbs her secretary Rei Hououmaru (who until then had done almost nothing) into her body, to power her ultimate outfit. Hououmaru stoically resigns herself to her fate. Rei had after all always wanted the entire human race, including herself, to be consumed by the life fibers. When she is forcefully ejected from Ragyo in the next episode, [[TheDragon Nui Harime]] feeds herself to the [[PlanetaryParasite Primordial Life Fiber]], which then fuses with Ragyo.
* ''{{Manga/Naruto}}''
** Orochimaru intended to do this with Sasuke. [[spoiler:It ended up going the other way around.]]
** Also, [[spoiler: Kabuto later integrates Orochimaru's]] remains into his body to make himself stronger. It was ambiguous for a while who had devoured who, but [[spoiler:Kabuto]] seemed to be more-or-less in control. [[spoiler:Orochimaru ''still'' came back, just via a different route. He then reabsorbed the bits of himself in Kabuto]].
** Possession of the Rinnegan falls under this. After Pain's death, Tobi killed Konan and stole the Rinnegan from Nagato's corpse in order to gain a massive power boost for the upcoming war. Much later [[spoiler:Madara used Black Zetsu in order to take the Rinnegan from Obito for himself, though with TheReveal Nagato's Rinnegan was actually his to begin with in life, it was more a matter of taking back what was always his]].
** At the climax of Anime/BorutoNarutoTheMovie, [[spoiler:there's a rare case where TheDragon actually asks the BigBad to do this. In order for his master to defeat the heroes, Kinshiki implores Momoshiki to absorb him to gain his power, and asks him not to hold back. Momoshiki's only offended that Kinshiki ever thought he'd actually hesitate, then turns him into a chakra fruit and devours with him a SlasherSmile afterwards. Even though the subordinate was willing in this scenario, it still marks Momoshiki as a particularly loathsome villain since Kinshiki loved him, raised him and thought of him as a son, and Momoshiki proved he never cared about him at all.]]
* Inverted in the ''Anime/MegaManNTWarrior'' manga. When the good guys finally get the current villains on the ropes, BigBad [=LaserMan=] decides it's best to make a strategic retreat and regroup. [=MegaMan DarkSoul=] decides he'd rather "regroup" his superior's power with his own, deals a finishing blow, and proceeds to take the "devour" portion of this trope quite literally.
-->'''[=MegaMan DarkSoul=]:''' A bit bland... but ''filling!''
* [[BigBad Mag Mel]] from ''{{Anime/Bakugan}}'' [[spoiler:kills and absorbs Mistress Sellon after she had [[YouHaveOutlivedYourUsefulness outlived her usefulness]], using her energy to power himself as he prepares to carry out his ultimate plan. The very next episode, he does the exact same thing to Anubias.]]
* In ''Anime/SuitePrettyCure'' [[spoiler:Noise absorbs Falsetto to power up and cross the BishonenLine.]]
* The Heroic version of this trope occurs twice in ''Manga/JoJosBizarreAdventure''. The first is with Jonathan Joestar and his mentor Zepelli, who gives Jonathan all of his Hamon power shortly before his death. A similar scene occurs with their grandsons Joseph and Cesar in Part 2.
* [[BigBad Alexander]] does this to his {{mooks}} during the FinalBattle of ''Anime/YuGiOhCapsuleMonsters'', sacrificing their monsters to summon Reshef the Dark Being and making sure that when his Reshef is attacked, they take damage instead of him.
* Amon did this in ''Anime/YuGiOhGX'', sacrificing his partner Echo to the spirit of Exodia to gain the power required to use Exodius the Ultimate Forbidden Lord. And Echo was [[UndyingLoyalty only too willing to comply]] to help him; given how selfish Amon was ([[RagsToRiches saved from death as a child by a rich man's generosity]], given all he ever wanted, never wanting for anything but then never being satisfied and wanting more), you have to wonder just what he ever did to earn such loyalty.
* A heroic example in ''Anime/{{FLCL}}'', where Canti powers up by devouring Naota, using him both as sort of a replacement for his missing parts and as [[FastballSpecial living ammunition for his]] BFG form. He survives each time, though, and is eventually...er...[[ToiletHumor passed out.]]
* This is the theme of the [[BlackKnight Shadow Paladin]] and [[DinosaursAreDragons Tachikaze]] Clans in ''Anime/CardfightVanguard'', with the Tachikaze taking it much more literally by actually devouring their allies (their clan's keyword is even called 'Engorge') and being 'dragons'.
* In ''Manga/{{Berserk}}'', [[TheEmperor Emperor Ganishka]] attempts to ascend to godhood through a ritual that involves him [[YouWillBeAssimilated assimilating]] the lives of most of his remaining minions using his magical fog. He gains a much, ''much'' stronger form in the process, but unfortunately for him he's still noticeably weaker than a [[DemonLordsAndArchdevils Godhand]] like Femto.

[[folder:Card Games]]
* One of the block mechanics is ''TabletopGame/MagicTheGathering'' was called "Devour" and worked via your creatures coming into play and "eating" other creatures you had in play for various benefits.
* ''TabletopGame/YuGiOh'': This is actually part of the overall mechanic. Monsters over Level 4 require you to [[NeverSayDie Tribute]] one or more of your other monsters to summon them. And unless your entire deck is dedicated to the WeakButSkilled, [[YouBastard you]] ''[[YouBastard will]]'' [[YouBastard do this]].
** Not just Tribute Summoning. Fusion, Ritual, Synchro, and Xyz Monsters usually require at least one - and usually more - monsters to summon properly, and that's very often the case with most other monsters that are special summoned via their own effects. Long story short, this is such an important part of summoning monsters in the game that it's ''very'' hard to make a working strategy without doing it. (However, the anime almost never depicts this as a bad thing unless you ''hurt'' them on purpose while doing so, like Pandora did.)
** Although, a few cards that require Tributes can be a ''little'' disturbing. For example, the Beast-Warrior Man-Thro-Tro can damage your opponent if you Tribute other monsters (Normal Monsters only, and Tokens don't count) and the card art suggest it does this by ''[[GrievousHarmWithABody throwing]]'' [[GrievousHarmWithABody the Tributed monsters at the opponent.]] Even squickier is [[http://yugioh.wikia.com/wiki/Insect_Queen Insect Queen]]; in order for her to even attack, you have to Tribute another monster, and in the anime, this is interpreted as [[HunterOfHisOwnKind the monster eating the Tributed monster.]] Even worse, when her attacks successfully destroys monsters, you get to summon Insect Tokens, which the anime depicted as her eggs; the idea is to use the Tokens as Tributes for her to attack, which means [[FridgeHorror the Insect Queen is willing to eat her own young.]] (Not that this isn't ''uncommon'' for some insects, but Insect Queen is horrific enough without knowing that.
** [[PhysicalGod Obelisk the Tormentor]] has this as his effect. After the usual Tribute Summon, sacrificing two more monsters lets him destroy all of the opponent's monsters.

[[folder:Comic Books]]
* In ''The ComicBook/ImmortalIronFist'', Orson Randall does the HeroicSacrifice variant by giving up his chi to power up Danny Rand.
* In ''ComicBook/JLAAvengers'', The Vision fires his solar beam (emptying his solar cells) at Superman to re-energize him when he is being attacked by several villains using Red-solar energy, and ''Kryptonite''.
* Another HeroicSacrifice version: ComicBook/TheKingpin once had a henchman called the Answer, who was pretty much an IneffectualSympatheticVillain, but one good thing he did was give up his life energy to save the life of the heroine [[ComicBook/CloakAndDagger Dagger]]. (He [[OnlyMostlyDead got better later]].)
* Bloodscream, a sort of vampiric monster, partners with Cylla Markham to track down and kill Wolverine. When they find him, Bloodscream drains the blood from Cylla to replenish his strength, revealing that the only reason he'd brought her along was to feed on her.
* During ''ComicBook/AvengersVsXMen'', 5 of the ComicBook/XMen each receive a portion of the Pheonix Force. When one is knocked out, the others get their portion of the power. In the end, there are only two left, Emma Frost and Scott Summers. Scott is on the ropes, so he knocks Emma out, allowing him to become the complete Pheonix.

[[folder:Fan Works]]
* In ''[[FanFic/DayOfTheBarneyTrilogy Day of the Barney]]'', [[spoiler:Barney kills Baby Bop in this manner]].
* The [[BadFuture Dark World]] arc of the ''FanFic/PonyPOVSeries'' plays with this trope. [[spoiler: When Discord is betrayed by [[SixthRangerTraitor Rancor]] and mortally wounded, [[DaddysLittleVillain Fluttercruel]] tries to ''invoke'' this trope, begging him to absorb her to heal himself. Discord refuses, since she's the one being he actually cares for, then inverts the trope by giving her his remaining power, allowing her to [[OneWingedAngel become a true Draconequus]] and the (apparent) FinalBoss.]]
* ''FanFic/FriendshipIsAura'': [[spoiler: [[DiscOneFinalBoss Chrysalis]]]] absorbs most of her minions in the hope of one last power-up against Lucario. It still isn't enough.
* In ''Fanfic/ADifferentLesson'', Heian Chao attempts to do this with Wu Xiu. Interestingly, both are actually gaining from this, Xiu being healed from Chao's powers and Chao feeding off Xiu's chi. Fortunately, a [[ThrowingYourShieldAlwaysWorks thrown shield]] from Po (the Shield of Fire Monkey Pass, no less) severs the connection that is making this possible. [[spoiler:as a result, Xiu is rendered comatose while Chao is hurled to the ceiling.]]
* ''Fanfic/TheBridge'':
** The Shadow of Red absorbs the strength of his minions when they are slain.
** After seeing his subordinate Monster X's true power as [[SuperPoweredEvilSide Kaizer Ghidorah]], Bagan decides he wants it for himself, so he orders Enjin to kill him, absorb his power, and return with it. It ends in failure when X fights back and ultimately kills Enjin. Unperturbed, Bagan decides to keep X as a loyal minion (since X has no idea Enjin was working for Bagan), and then drain X's power personally when he feels X has outlived his usefulness.

[[folder:Films -- Live-Action]]
* ''Film/HighlanderIIITheSorcerer'': Kane kills one of his CoDragons after they have been [[SealedEvilInACan released from their underground prison]] in order to gain his power and [[ThereCanBeOnlyOne weed out his remaining opposition]].
* ''Film/HighlanderEndgame'':
** Connor [=MacLeod=] forces his younger kinsman Duncan [=MacLeod=] to take his head and absorb his power, and thus have enough power to defeat the BigBad. Sort of a PassingTheTorch moment as well, as it's the hero from the original movie sacrificing himself for the good of the hero from the spinoff TV series.
** Jacob Kell also kills his mooks to gain their energy. Had the film been edited together with any sort of care, this scene would have come after Duncan gaining Connor's power. Instead, it comes somewhat randomly near the end.
* ''Film/HellraiserIIIHellOnEarth''. After Pinhead's shortlived right hand Monroe fails to offer Terri to him, Pinhead convinces her to instead take Monroe's place by his side and feed Monroe to him, [[FaceHeelTurn which she obliges]]. The power is enough to give Pinhead humanoid form again.

* In the climax of ''Literature/PhoenixAndAshes'' by Creator/MercedesLackey, [[spoiler:the wicked stepmother drains her lawyer/sidekick/future son-in-law completely of life, and drains her two daughters until they are [[LiquidAssets aged, withered, senile husks of their former selves.]]]]
* ''Literature/HarryPotter'': The final book largely revolves around the [[ArtifactOfDoom Elder Wand]], which transfers its loyalty (and thus, full power) to whomever manages to defeat its previous "master." At the beginning of the series, its master is [[spoiler:[[BigGood Albus Dumbledore]]]], who is killed by one of the CoDragons, [[spoiler:[[DoubleReverseQuadrupleAgent Severus Snape]]]]. When [[BigBad Voldemort]] gets his hand on the Wand, he kills said servant so that he can become its new master. [[spoiler:Except Dumbledore actually wasn't its master by the time Snape killed him...]]
* ''{{Literature/Discworld}}''
** ''Discworld/WitchesAbroad'' has Lilith draining all ambient magic from the ballroom in order to throw an attack at the Baron. The Duc (who's actually a frog given human form, as Lilith [[TheoryOfNarrativeCausality has a thing for making things work based on stories]]) reverts to his true form instantly.
** Although non-magical, [[spoiler:Mr. Pin's killing of Mr. Tulip]] in ''Discworld/TheTruth'' is a similar case of a villain sacrificing his most trusted ally in order to shield himself.
* Variation in the last book of ''Literature/TheWheelOfTime'', where [[MouthOfSauron Shaidar Haran]] [[spoiler: is sacrificed to further weaken the Dark One's prison and allow it to manifest more fully in the physical world]]. What makes it unusual is that Shaidar Haran [[spoiler: was actually a sort of weaker copy of the Dark One to begin with]] so the Dark One didn't so much steal his power as [[spoiler: take back what had been given]]. As [[TheAntichrist Moridin]] said, Shaidar was [[spoiler: "A vessel of my Master, one that is no longer needed."]]

[[folder:Live-Action TV]]
* In the penultimate episode of ''Series/JukenSentaiGekiranger'', Long devours his loyal servant Sanyo after transforming into his [[ScaledUp true form]], which ironically is a dragon itself. ([[SoulJar Sanyo was actually a part of Long]], which enabled him to survive his body's prior destruction at the hands of the Gekirangers.)
* ''Series/PowerRangersLightspeedRescue'' has Queen Bansheera get the last bit of power she needs to complete her transformation from a scarred and damaged near-cocoon like state to a fully mobile and powerful humanoid one by draining Vypra, citing her many failures as reason for this punishment.

[[folder:Tabletop Games]]
* ''TabletopGame/DungeonsAndDragons''
** In the adventure [=OA5=] "Mad Monkey vs. the Dragon Claw", this is a special ability of Dragon Claw martial artists: the most senior one present can drain HitPoints from his fellow Dragon Claws, allowing him to fight longer. If the heroes fail, the Dragon Claw statue will do this to all Dragon Claw fighters in Kara Tur.
** The ''Death Knell'' spell from Third Edition allows an evil cleric to do this to a dying comrade.
** A number of powers of the Dark Pact, a warlock pact from Fourth Edition, have the warlock draining Hit Points from his allies to power his magic. Being as the Dark Pact was originally created by the Drow, who are natural backstabbers who hold absolutely no faith in friendship or fellowship... yeah.
** During the Time of Troubles in the TabletopGame/ForgottenRealms, Bhaal absorbed the souls of every assassin in the world in order to upgrade his avatar. To gain the strength to battle Bhaal's avatar, Torm likewise absorbed the souls of his own followers, but on a voluntary basis. This was done to justify the lack of an assassin class in 2nd Edition ''Dungeons & Dragons'' in-universe.
* In the climax of the "Enemy Within" ''{{TabletopGame/Warhammer}}'' campaign, the Big Bad drains lifeforce from the official he has been mind-controlling, allowing him to take his true form.

[[folder:Video Games ]]
* Seen in ''VideoGame/ResidentEvil4'' as [[spoiler:Salazar and his remaining Verdugo fuse with a Queen Plaga before his fight with Leon.]]
** In ''VideoGame/ResidentEvil5'', Wesker injects Excella with the Uroboros parasite, which devours her from within.
* ''VideoGame/WarCraft''
** In ''VideoGame/WarCraftIII'', the Death Knight hero can use the ability 'Death Pact' to sacrifice any non-Hero undead to restore health. The Lich can do the same thing for mana.
** The ability also appears in ''VideoGame/WorldOfWarcraft''.
** And in ''VideoGame/StarCraft'': The Defiler can "Devour" another Zerg to recharge their ManaMeter.
** In ''VideoGame/StarCraftII'', the hero character Tosh can remove health from a nearby biological unit to recover energy, which is used to cast spells.
* ''Franchise/{{Castlevania}}''
** In ''VideoGame/CastlevaniaPortraitOfRuin'', Dracula [[spoiler:reaches his OneWingedAngel form by consensually taking Death's soul. "My power! Use my power!"]]
** In ''VideoGame/CastlevaniaCircleOfTheMoon'', beating one Zombie Dragon boss will cause the other to chew at (and gain HP from) the one you just killed, making this a literal case of devouring dragon.
* In ''VideoGame/MortalKombat9'', Shao Kahn absorbs Shang Tsung and gives some of his power to Sindel.
* A [[VillainProtagonist "heroic"]] version is the central gimmick of ''VideoGame/ValkyrieProfileCovenantOfThePlume''. Your buddy is supercharged, [[DeadlyUpgrade dies at the end of the battle]], and you get a power-up.
* In ''VideoGame/JadeEmpire'', Smiling Hawk takes a bit of a beating from the player before his most devoted disciple arrives. Smiling Hawk decides that the disciple's life would be more useful than his help.
* A variation in ''VideoGame/KnightsOfTheOldRepublicII''; Visas Marr, having originally been TheDragon to [[TheHeartless Darth Nihilus]] and possessing a Force Bond to him, could be made during the fight against him (having [[HeelFaceTurn joined the Exile]]) to commit suicide in order to weaken Nihilus. Visas just has to be either wearing her default outfit, or in her underwear, and can only be armed with a basic lightsaber. Her RelationshipValues must also be at maximum.
* Inverted in ''VideoGame/FinalFantasyX'', when one of [[spoiler:Seymour's]] incarnations features "morticorpus", a living shield that regenerates by draining his life.
** He does play this straight right before that BossBattle, though, by absorbing the body of the recently deceased Maester Kinoc (who was killed by Seymour offscreen shortly before) along with four of his own mooks in order to jumpstart his transformation into the OneWingedAngel form that includes the morticorpus.
* In ''VideoGame/LegendOfMana'', after the Hero beats Lord of Jewels 999, its dragon Sandra offers it her core gemstone so it could be reborn as Lord of Jewels 1000.
* ''Franchise/DragonAge''
** In ''VideoGame/DragonAgeOrigins'', a Blood Mage can drain health from other party members with "Blood Sacrifice", which is a good way to keep the Blood Mage alive since keeping "Blood Magic" active renders other forms of healing all but useless. If you're careless it's entirely possible to bring your ally to the brink of death.
*** In Origins, this is even a mechanic in a boss fight. A powerful [[ImAHumanitarian Tevinter mage]] in a later mission starts draining his minions of blood to fuel powerful AOE attacks that can really mess up your party if you're not keeping track of his health. However, if you have all four party members close in to attack the minions before he can drain them, you can kill them first, and beat him before he can really use the technique. If you kill every minion before you beat him, you even get more experience points!
** That's what the ranger's summoned pet is for. [[VideoGameCrueltyPotential Well, that and disarming traps...]]
* Inverted at the end of ''VideoGame/SilentHill3'': Claudia devours the embryonic God to enable its birth, which of course destroys her.
* In ''VideoGame/TheLegendOfZeldaSpiritTracks'', BigBad Malladus was forced outside of Princess Zelda's body. With no convenient way to repossess her, Malladus opts to simply possess his not-as-compatible Dragon, Chancellor Cole, creating an unstable beast that serves as the FinalBoss.
* In ''VideoGame/SoulNomadAndTheWorldEaters'', Thuris drains Kanan, the leader of his cult for a power boost before his boss battle after the rest of his cult wasn't enough.
* In ''VideoGame/SoulCalibur 4'', Tira ''wants'' Nightmare/Soul Edge to do this to her because she has a bad case of MadLove for it. In her ending, [[spoiler:the opposite happens. Nightmare's body can no longer withstand its own power and dies while Tira begs him to stay with her. Tira gets her wish when Soul Edge's power merges with her.]]
* Mother does this to Zeikfried in ''VideoGame/WildArms1''.
* In the DualBoss battle against Ornstein and Smough in ''VideoGame/DarkSouls'', defeating one of them will cause the other to regenerate his health and absorb his fallen comrade's power. Smough gets Ornstein's lightning, while Ornstein becomes gigantic.
* ''VideoGame/StarWarsTheOldRepublic'': The Sith Inquisitor has the "Sacrifice" ability, which [[ExactlyWhatItSaysOnTheTin sacrifices]] your companion in order to restore health to yourself. Depending on how you play your character, your companion might indeed be TheDragon to your BigBad. The Inquisitor also consumes [[spoiler:force ghosts]] during the story to gain the power to confront his/her nemesis.
** All classes get this ability, if they get to level cap and full dark-side.
* In ''VideoGame/{{Prototype 2}}'', [[spoiler: Alex Mercer]] prepares for the final battle by consuming [[spoiler: his Evolved lieutenants]].
* In the final battle against Miraak in ''VideoGame/TheElderScrollsVSkyrim'' [=DLC=] ''Dragonborn'', Miraak fights you while three dragons fly nearby. Each time he is brought near death he will absorb one of his dragons' souls to restore his health.
* In ''VideoGame/HauntingGround'', a New Game Plus cutscene shows [[spoiler: Lorenzo, a creepy old paraplegic and the real BigBad of the game, crawling over to the defeated body of Ricardo. He sucks out Ricardo's Azoth through his mouth. Though its effects are not immediate, this is why Lorenzo starts off as a crazy old man and ends the game as a nearly indestructible young sorcerer. Azoth is the source of life in alchemy.]]
* Near the end of ''VideoGame/PerfectDarkZero'', Zhang Li absorbs [[TheMole Chandra]]'s life force [[YouHaveOutlivedYourUsefulness after she brings him the Graal]].
* In ''VideoGame/{{Tekken}} 3'', Ogre absorbs Heihachi(or Jin if playing as Heihachi) after the first round, resulting in him going OneWingedAngel.
* ''VideoGame/FinalFantasyXIV''
** Inverted in the Extreme Mode version of the [[WolfpackBoss King Moggle Mog]] fight. Whenever one of the Mogglesguard is killed, Moggle Mog will revive and heal them [[CastFromHitPoints at the cost of his own health]]. This is actually the only way to damage him, as he is invulnerable as long as the Mogglesguard are alive.
** A more classic version plays out in the battle again [[spoiler: King Thordan]], who was made a primal through Lahabrea's machinations. Knowing that the Ascians are manipulative and would most likely use him for their own ends, the first thing [[spoiler: Thordan]] does with his new godhood is kill Lahabrea and devour his aether, destroying his immortal existence.
** The boss of Hard Mode Haukke Manor summons various adds throughout the fight. Shortly thereafter she sucks their blood to fuel a devastating Blood Rain [=AoE=] attack. The lower their health when they're eaten the lower the resulting damage will be.
* ''VideoGame/DarkSouls'' has Ornstein and Smough; whichever dies first will be absorbed by the one still alive for a significant power boost.
** ''VideoGame/DarkSouls3'' has the [[PhysicalGod Nameless King]], who has two phases; one where he rides a dragon companion, and a second one where he fights man to man. Once the dragon phase ends, the King absorbs it and then fights you himself.
* In ''VideoGame/ShinMegamiTenseiStrangeJourney Redux'', the TrueFinalBoss, Shekinah, will summon her lackey Demeter when she's on the ropes, commanding her to use her lifeforce to restore her to peak performance. Reluctantly, Demeter complies.

[[folder:Visual Novels]]
* Rare ''heroic'' variant: In GirlsLove VisualNovel ''VisualNovel/AkaiIto'', Tsudura [[spoiler:eat Obana's corpse]] because she doesn't want to [[FriendlessBackground lose her only friend]] (in a battle versus [[BigBad Nushi]]'s [[TheDragon dragons]], at that). {{Squick}} doesn't even begin to describe the scene. The result is that Tsudura turns into an uberpowered [[NinjaPirateZombieRobot werefox-mage-exorcist]], or something.

* In {{Webcomic/Homestuck}}, [[TheChessmaster Dr]] [[TheOmniscient Scratch]] had to [[ThanatosGambit die]] because [[spoiler: he was the host body for [[BigBad Lord English]]]].
* During the FinalBoss fight in ''Webcomic/KidRadd'', Radd is brought down to 1 health and is about to be finished off with an unavoidable attack when [[spoiler: Bogey forces Radd to kill him so that he can get a health power-up.]]
* ''WebComic/SluggyFreelance'': In "Holiday Wars", [[TheVirus Alien]] [[SantaClaus Santa]] absorbs ''all'' his underlings to prepare against the onslaught of Bun-bun's army, becoming a giant killing machine. His real power lies in [[LethalHarmlessPowers creative use of his holiday powers]], though...

[[folder:Web Original]]
* Implied to have happened in ''WebVideo/ThereWillBeBrawl'', when [[spoiler: [[BigBad Kirby]] is revealed to still be alive, there are no signs of either of his Dragons, and he's wearing the cap of one of them. Now, remember that Franchise/{{Kirby}}'s powers involve copying the powers of other characters by literally eating said characters, and he usually dons a hat reflecting said powers...]]

[[folder:Western Animation]]
* {{Inverted}} in ''WesternAnimation/{{WITCH}}'': [[spoiler:Cedric eats Phobos to gain his powers]].
* As noted in the page quote, Makuta absorbs [[BrainsAndBrawn Nidhiki and Krekka]] in ''Toys/{{Bionicle}}: Legends of Metru Nui'', as well as his pet FeatheredFiend Nivawk after he [[YouHaveOutlivedYourUsefulness found the need for their services irrelevant]]. This was a mixed blessing however; he later claimed that he had trouble suppressing their minds within his own, distracting him enough for the heroes to win.
* In ''WesternAnimation/{{Wakfu}}'', Goultard dominates the fight against Rushu. Realizing he's in a bad position, Rushu calls upon his Shushu hordes to help him, and they merge into a huge mass of darkness. Rushu ''eats'' it to get a power boost that allows him to gain the upper hand against Goultard.
* A literal example in ''Dinofroz''. Before the final battle, dragon king Neceron zaps his three generals to gain their powers, leaving them dying. Oddly enough, despite him explicitely saying that they will die without their powers, the three dragons appear later alive and well, although two of them die for different reasons.
* In the ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' episode ''[[Recap/MyLittlePonyFriendshipIsMagicS4E26TwilightsKingdomPart2 Twilight's Kingdom Part 2]]'', Lord Tirek convinces Discord to pull a FaceHeelTurn, then turns on him and steals his magic when he's done with him.
* A variation occurs in ''WesternAnimation/TransformersGeneration1''; Megatron's plan was to lure the Autobots to their doom using a device that created a clone of Optimus Prime, but the plan was jeopardized when the real Optimus showed up. Then Megatron had a good idea; in order for the clone to win the trust of the heroes, he'd have it fight - and ''kill'' one of the high-ranking Decepticons. Meaning Starscream. Then he figured, [[CantKillYouStillNeedYou he didn't have to sacrifice Starscream]], he'd use the same device to clone ''him''. (Well, maybe he ''could'' have stood to get rid of Starscream, but that was another issue.) And to make it even more convincing, he had Starscream control it remotely. (So it would be just as arrogant [[EvilIsHammy and loudmouthed]] as the real one.) In fact, this almost worked, the thing that gave the clone away being it disregarding Spike as "unimportant", [[OOCIsSeriousBusiness a serious faux pas that ruined the whole thing.]]
