Didn't Need Those Anyway

Almost invariably, Action Adventure games and similar works will have the Player Character face off against at least one enemy that wasn't quite built to specifications. Whether they are made of organic matter, metal, stone or some kind of Applied Phlebotinum, these kinds of enemies will often begin to "lose" pieces of their weaponry, armor or even actual body parts as they take damage, by having them either just drop off or self-detonate. This is rarely detrimental, however, as most are either unfazed by the loss, or have an even more powerful alternative waiting.

This trope is commonly featured by a Heavily Armored Mook, requiring the Player Character to remove the armor before the "coup de grace" may be administered. Of course, in keeping with the trope, the enemy typically becomes faster and/or stronger as they lose this extra baggage.

The key to this trope is that losing their primary equipment never seems to hinder the enemy, and can, in fact, act as a Berserk Button, especially if the enemy in question is the Big Bad. The main difference between this and Cognizant Limbs is that the lost equipment does not act on its own, and is not usable by the enemy after it is gone, as it typically disappears. In effect, this trope is the opposite of Critical Existence Failure, since the damage done to the enemy does show noticable effects even before permanently killing them.

Compare Heavily Armored Mook, as mentioned, Cognizant Limbs, where destroyed body parts live on as weapons for the enemy, and Only a Flesh Wound, where damage to non-vital body parts doesn't seem to faze an enemy. Contrast Critical Existence Failure, as mentioned.

Film

 * The Black Knight from Monty Python and The Holy Grail, who keeps fighting after losing both arms and legs.

Literature

 * Hercules: The classic story of Hercules and the Hydra can be considered a non-mechanical version of this trope, as Hercules has to remove the Hydra's extra heads and the process only makes things worse....

Video Games
"GLaDOS: That thing you burned up isn't important to me; it's the fluid catalytic cracking unit. It makes shoes for orphans... Nice Job Breaking It, Hero."
 * House of the Dead: Chariot, the first boss, has only a tiny point in his breastplate where it takes damage. Pump enough rounds into the nick and he flexes his muscles, literally exploding out of his armor. Then you effortlessly blast the flesh off his bones.
 * Banjo-Tooie:
 * Targitzan. He's a giant totem composed by a head and four rotating pieces. As you shoot at the (literal) targets, the boss's height decreases.
 * Old King Coal, a monster made of coal loses body parts as you hurt him, first one arm, which he dismisses casually, then his other arm, which he's perturbed by, but otherwise unfazed, then the entire upper half of his body, whereupon he suddenly starts wondering if you'd like to sit down and talk about this.
 * The last boss of Disgaea 2 has a number of shields/masks on him that disappear once he takes a sufficient amount of damage and with them, his resistance to elemental attacks.
 * Donkey Kong 64: Similar to the Banjo Tooie example, also made by Rare, this game has King Kut-Out (a cardboard cut-out of the Big Bad, King K. Rool) loses fist one arm, then the other, then his head, whereupon he dies. Given that the Kongs were firing themselves out of cannons at him, this is, perhaps, understandable.
 * Mangoruby in Donkey Kong Country Returns. The electrified caterpillar's body will explode into parts as it's hit by Donkey and Diddy, but this makes it faster and more vicious as a result.
 * Kirby: In Kirby Super Star, many of the mechanical bosses Kirby must oppose have extra guns that can be blown away.
 * 'The Legend of Zelda'A Link to The Past'': One of the bosses in the Dark World requires you to remove globular masses from his body in order to damage him.
 * Ocarina of Time: The boss inside Lord Jabu-Jabu requires the player to kill the jellyfish serving as his armor. Also, Stalchildren would lose their heads if you slashed them with your sword in a certain way. Being skeletons, this did nothing to stop them from attacking you.
 * Iron Knuckles from both Ocarina of Time and Majoras Mask drop off pieces of armor when you inflict a certain amount of damage to them. Better be on your toes when that happens, because it makes them much, much faster (to a lesser extent in Ocarina of Time, though).
 * Dark Nuts in Wind Waker become faster as they lose pieces of their armor and if Link manages to knock the sword out of their hand, they suddenly switch to a hand-to-hand combat style where they are actually more dangerous than when they had the sword.
 * The Legend of Zelda Twilight Princess: Toward the end of the game, Link must wear down his heavily armored foes called Darknuts, by removing their armor piece by piece. Once it's removed, they toss their massive weapon and draw a longsword, and become capable of doing combos.
 * Koloktos in The Legend of Zelda Skyward Sword will lose its arms every time you pull them away with your whip.
 * Star Fox: In the original and N64 versions, the first boss is an aircraft-carrier of sorts that will lose pieces of its ship as you damage it.
 * World of Warcraft: Many of the Earth Elemental enemies will begin to lose actual body mass as you damage them. Often it does weaken them, though sometimes it simply leads to smaller copies of the elemental attacking you as well.
 * The final boss of the Tournament of Champions five man dungeon, the Black Knight, goes through three incarnations as you battle him. First he is an armored Death Knight, then after you beat him down, he comes back as a skeleton. Finally he's a malevolent ghost. "My rotting flesh was just getting in the way."
 * It should be noted that, as both his name and the name of one of the player achievements associated with the fight would suggest, this boss is an obvious Pop Culture Reference to the infamous Monty Python Black Knight mentioned under the film tab above.
 * Yoshis Island: One of the bosses, Salvo the Slime, is made of some sort of gel-like substance. Yoshi must shrink him by damaging him and causing his gel-like mass to evaporate.
 * Legend of Spyro: Dawn of the Dragon has the Golems, one of which deliberately breaks off a body part to free itself from entrapment and later replaces it by assimilating nearby wreckage. Then its big brother gets about a third of its total body mass broken off in the course of the level where you fight it, and keeps on going after the level ends, playing the trope very literally.
 * Clean Asia: The boss in China stage comes with four tentacles that spray bullets. Destroying them all makes the boss unleash an even bigger spray of bullets.
 * Dynamite Headdy has The Wooden Dresser, a giant wooden figure model that can't be damaged until you knock all of the clothes off of it first. A few seconds later, it will summon another costume. Then there's a semi-example in Baby Face, a giant mechanical Baby's Face that sheds faces for progressively older (and thinner, and tougher) ones as the battle goes on. If any of this sounds weird it's because it is.
 * The DS remake of Final Fantasy IV has the Octomammoth treat its first six tentacles this way.
 * Final Fantasy VII has Mighty Guards in the Shinra HQ. Mooks met early in the game, these are highly armoured and red. Once you beat them enough, the armour falls off, revealing a slender, greyish, and faster, but weaker, mook.
 * Castlevania II: Belmont's Revenge features the Iron Doll. At first, it's a demon in a huge suit of amour that lumbers around slowly and swings its sword at you. After half his life is gone, he sheds his armour and gains a LOT of speed, leaping all over the place and shooting laser blasts from his sword.
 * Castlevania Bloodlines has the Golem as the boss of Stage 2. You have to whip away at his segments, then whip his head which proceeds to blow up, revealing his core.
 * N.Gin in Crash 2 is a good example. He starts with two lasers in his mech's arms. You destroy those, and he reveals that his shoulders contain rockets. Destroying those make him use a cannon he had built into the mech's chest. Destroying that then blows his device up.
 * Several Sonic bosses qualify for this:
 * Destroying all seven of the miniature Robotnik Balloons in the Metropolis Zone leaves Robotnik to reveal his craft also has a laser to attack you with.
 * Every hit to the final boss of Sonic CD will cause him to lose one of his four spinning arms, also changing his attack pattern entirely.
 * The main boss of the Ice Cap Zone, starts with a platform that he raises up to goad you into attacking while he tries to freeze you. It gets broken off after six hits, leaving him to just float around spewing the freezing gas.
 * The second boss of act two of the Launch Base Zone will lose both his laser cannons leaving you to just try to hit him as he flies up and down.
 * The sub-boss of Lava Reef has two bullet firing tentacles that can be destroyed. It doesn't make any difference to the fight if you do or don't (save for making one less obstacle to avoid), as the boss ends once you've hit the giant hand six times either way.
 * The Final Boss of the Death Egg Zone in S3&K will start attacking you with just his giant fingers. Once you smash those off one by one, he reveals he's turned the Master Emerald into a powerful laser cannon.
 * The boss of Panic Puppet Zone will simply lower down to another floor if you destroy the two weapons on that floor, until you've destroyed six separate weapons.
 * Every nonhuman enemy (except the final boss, who possesses instant regeneration) in Valkyrie Profile 2 is subject to this: all major body parts have their own hidden HP count and are severed when it is depleted, allowing the party to end up fighting huge dragons with only a single limb left if they so desire. This also ties in with Randomly Drops, in that severed enemy parts have a set percentage of becoming items, but thankfully never dropping below a 15% chance (due to the difficulty of actually chopping off the right enemy part without killing the enemy outright, as you can't specifically target the body parts themselves, and exactly what you end up hitting is determined by what attacks you use and the enemy's position.)
 * Done rather brutally in God of War 3, where during the battle with Hades, Kratos must rip whole chunks of flesh off his body. Then you have to "kill" the chunks before they slide across the floor and reattach themselves to Hades' body.
 * Also done with Herakles, who speeds up as he gets his armor knocked off.
 * Herc also kinda paraphrases the trope name once his last piece of armor is gone: "ARMOR IS FOR WEAKLINGS!"
 * The original game has the giant armored Minotaur fought in the temple. You knock off pieces of its armor until the beast itself finally becomes vulnerable to damage.
 * Gets done to a ridiculous extent in the Monster Hunter series. Almost every boss has "breakable" parts, which either scar or are removed outright from the body after enough damage is on a centralized area. It gets ridiculous when you break a monster's beak, back, claws, and sever its tail, yet it still continues to attack without showing an ounce of pain. There is also a monster, the Barroth, which can have part of its skull severed and it still fights at full force.
 * in Metal Gear Solid 4.
 * The Harrier from MGS2 as well, although it's not necessary to shoot parts of it off the main boss.
 * Baten Kaitos gives us the Magnus Giganticus boss battle. Magnus Giganticus is a Gigantic Magnus produced when  As you fight Magnus, its four corners are torn off one by one until you're fighting a jagged edged rhombus with magical powers.
 * Bayonetta has the Cardinal Virtues, a quartet of huge bosses that you face throughout the game. As the fight progresses, you rip off parts of their body using Prehensile Hair, which at best makes them turn red. However, at the end of each fight, despite having at least 50% of their body gone, they give their last words as though they weren't in some sort of excruciating agony.
 * Applies to normal enemies as well, which undergo a pretty severe Glamor Failure when they're near death, as their muscle tendons become exposed and gooey liquids drip from what's left of their skin.
 * Angel-like enemies that seem much less majestic once you've hacked at them a little is yet another thing Bayonetta carried over from Devil May Cry - in the third game, Dante faced off against four-winged angels who would use two wings to fly and two to cover their bodies with an invulnerable shield, and only be hittable when they dashed. After a couple hits, though, wings fall off, revealing snarling demonic faces on their torsos.
 * Bouldergeist from Super Mario Galaxy.
 * Portal combines this with hilarious Boss Banter:


 * Portal 2 inverts this. You defeat the final boss by
 * Plants vs. Zombies has zombies with armor you must destroy (or remove some other way, like with a magnet shroom) before being able to defeat them. And their arms fall off when they're really near death, finishing off with the fact that the heads fall off when they finally die.
 * The final boss of Assassin's Creed: Brotherhood loses parts of his armor to each of Ezio's Quick Time Event hidden blade attacks.
 * Ace Combat Joint Assault has . At first, it has a rear-facing point defence machine gun that destroys any missiles coming from the six. If you manage to damage it enough, though, it loses the PD gun and gains the ability to do ridiculous missile-dodging manoeuvres you could never replicate.
 * The first boss of Conkers Bad Fur Day, Haybot, loses parts of its body as Conker and Franky continue pressing the red button behind its body. When Haybot is complete, it attacks by squashing the characters with both hands. When one of those hands is gone, it attacks by seizing them and then throwing them away. With both hands gone, it squashed again the characters, but with its own metallic base. With the rest of the body gone, the boss is simply defeated.
 * Quadraxis from Metroid Prime 2. This is the reason why it's a Marathon Boss, as dismembering it part-by-part takes a very long time. It's only truly defeated when its head module is completely destroyed.
 * Lar, the final boss of Chariot - Adventure through the sky (a Shoot'Em Up included in Capcom's arcade collection Three Wonders) loses its entire body when you hit him enough, leaving only his floating head/mask.
 * Happens with most bosses of certain shoot'em ups, for example Aero Fighters, Blazing Star, and Strikers 1945. When receiving damage, they'll start to lose parts and/or (mostly and) change in another form almost always nastier -in the case of the latter Transforming Mechas-
 * Halfway through the fight with Mendez in Resident Evil 4, he ditches his human legs and swings around the shack monkey-style.
