''The top-level bosses in a game will be immune to the player's most effective or strongest attacks.''
 
Any magician, fighter, or hero with powers, abilities, or weapons that enable him or her to cut through [[Mooks]] [[Foe-Tossing Charge|like butter]] will ''rarely'' be able to use these skills on [[The Dragon]] or the [[Big Bad]]. In [[Video Games]] these enemies will be [[NoWon't SellWork On Me|flat out immune to these attacks,]] or in the case of a [[FPS|first person shooter]] be able to take ''head-shots'' and keep on ticking, while (annoyingly) players have no such protection from ''their'' [[One-Hit Kill|instant-death attacks]]. [[The Computer Is a Cheating Bastard|Where's the justice?]]
 
The reason programmers and authors do this is for game balance and narrative issues. Where's the big climactic and ''fun'' battle if the hero just lops off the enemy's head? A hero who can send the [[Big Bad]] into the [[Phantom Zone]], [[Taken for Granite|turn them to stone]], [[Made of Plasticine|cleave them limb from limb]], or otherwise kill/disable them in less than a heartbeat skirts [[Game Breaker|dangerously close]] to [[Boring Invincible Hero]].
 
Basically, they do it because [[Reality Is Unrealistic]]. However, this '''Contractual Boss Immunity''' ends up resulting in [[Gameplay and Story Segregation]] that will really bug players, or worse, ''harm them'' if they put a lot of their [[Experience Points|XP]] into powering up these abilities. Essentially, this is what puts the "Useless" in most [[Useless Useful Spell|Useless Useful Spells]]s, especially in [[RPG|RPGs]]s.
 
However, [[Averted Trope|averting]] this trope ''can'' make for a different and entertaining atmosphere. Allowing players to [[One-Hit Kill]] any enemy, [[Cherry Tapping|Cherry Tap]] even the [[Final Boss]], or characters to use the [[Touch of Death|Five Point Palm Exploding Heart Technique]] on [[Kill Bill|Bill]] can be downright ''[[Showy Invincible Hero|awesome!]]''
Line 15:
 
{{examples}}
== [[Anime]] and [[Manga]] ==
* ''[[Is It Wrong to Try to Pick Up Girls in a Dungeon?]]'' is an [[RPG Mechanics Verse]], and this trope appears in the final two episodes of the first season. Considering what it took to actually summon that particular Floor Boss, it's no surprise that everyone's usual finishing moves wouldn't work against him.
 
== Tabletop RPG [[Literature]] ==
* In the ''[[Percy Jackson]]'' novels, death is not permanent for the monsters of Greek Mythology (like Medusa, the Hydra, the Minotaur, and so forth); if killed, they are imprisoned in Tartaurus for a few centuries, and then reborn. This, of course, is the in-universe explanation for how they can be featured in the series as villains in the first place, as most were slain by the great heroes of that era.
 
== Video[[Tabletop Games: FPS ]] ==
* In ''[[Dungeons and Dragons]]'' golems are flat-out immune to spells that allow spell resistance unless otherwise stated, and even then, it usually either slows it or heals/hastes it. Oh, and we can't forget epic-level golems! The Mithral Golem is only DE-HASTED by an actual slow spell, and the Adamantine Golem is straight-up immune to everything (most epic monsters have a ton of immunities on their own). Even this though doesn't stop creative wizards who can bypass the immunities by not targeting the golem itself. Image creating illusions like silent image (mindless creatures don't have the reasoning capacity to disregard out of hand the river dancing gnolls that just appeared), buffing the meatshield and simply "greater invisibility"ing past them are all accepted methods to defeat golems.

** In ''[[Dungeons and Dragons]]'' golemsGolems are flat-out immune to spells that allow spell resistance unless otherwise stated, and even then, it usually either slows it or heals/hastes it.

*** In 3rd Edition onward, this is simplfied by assigning types to monsters and stating that certain types are immune to certain things. For example, Contructs (of which golems are a part of) are immune to all mind-affecting effects (charms, compulsions, phantasms, patterns, morale effects) even if they do have an intelligence score, poison, sleep-causing effects, paralysis, stunning, disease, death effects, necromancy effects, critical hits, nonlethal damage, ability damage, ability drain, fatigue, exhaustion, or energy drain, any effect that requires a Fortitude save, unless said effect works on nonliving objects. On the other hand, they cannot be healed (naturally or by magic, but they can be repaired), cannot be raised from the dead (because they were never alive to begin with) and while they cannot be killed by massive damage, they are immediately destroyed when reduced to 0 hp or less.
** But then any wizard can bypass SR if they're properly prepared, and there's a ton of spells that ignore SR anyways.
** There's also the psion-killer (psions basically being wizards using MP instead of [[Vancian Magic]]), a golem specifically designed, as one might infer, to kill psions (and by extension wizards/sorcerers).
** "[[The Order of the Stick (Webcomic)|Thrice-cursed]] [http://www.giantitp.com/comics/oots0437.html Spell Resistance]! It's almost like the universe is trying to deliberately force some form of [[Competitive Balance|arbitrary equality]] between those of us who can reshape matter with our thoughts and those who cannot."
** Fourth Edition largely averts this by not having a lot of potential instant-kill tricks in the first place. Elite and solo monsters ''will'' be tougher than standard ones (to say nothing of minions) and may take less damage from some attacks, but outright immunities to things player characters are likely to use often are relatively uncommon and conditions can be inflicted on these creatures as normal.
* ''[[Paranoia (game)|Paranoia]]'' gives certain NPCs "GM fiat armor" as shorthand for "beating this guy would really mess up the plot, [[Railroading|so whatever the PCs try]], [[Hand Wave|contrive]] some excuse for it to fail".
* ''[[Feng Shui (Tabletop Game)|Feng Shui]]'' has this built into the system. Enemies are divided into two tiers: [[Mook|Mooks]]s and 'Named Characters'. Named characters (which include the Player Characters, [[The Dragon]], The [[Big Bad]], and other bosses) have [[Hit Points]] and are resistant or flat-out immune to many effects that instantly fell Mooks.
 
== [[Video Games: RPG ]] ==
== Video Games:= Action ===
* In several ''[[Metroid]]'' games, there exists a "Speed Booster" item that acts as an instant kill to practicaly anything it touches. However, in ''[[Metroid Fusion]]'' {{spoiler|the SA-X}}, which was probably intended to be undefeatable, cannot be damaged by it (or by the derived ability called the Shinespark, which has the same effect on enemies as the Speed Booster).
** Same thing with Screw Attack. It instakills normal enemies but doesn't work on any boss. It is not completely useless, but generally only causes very little damage to the boss and you take some damage yourself or it has to be very precisely aimed (in this cases, though, it does deal MASSIVE DAMAGE).
* Bosses in ''[[No More Heroes]]'' are completely immune to regular attacks, unless they are struck during specific times during their attacks.
* In ''[[Cave Story (Video Game)|Cave Story]]'', [[Robot Girl|Curly Brace]]'s Air Tank generates a bubble shield that protects her from A) drowning and B) your Missile Launcher.
* The bosses of the [[Downloadable Content|DLC]] "special stages" in ''[[Mega Man 10 (Video Game)|Mega Man 10]]'' are completely immune to all of the secondary boss weapons (which you automatically receive when you begin the stage). Giving them no special weakness would have been one thing, but it's irritating that you can't even access those weapons' interesting attack patterns doing normal damage.
* The final boss in ''[[In FamousInfamous (Videovideo game Gameseries)|In Famous]]'' has this in spades. On easy mode all your attacks work, and he can be beaten quickly, and on normal mode your strongest doesn't work, but he can still be killed easily. On the [[Nintendo Hard]] mode? At least one of your skills will be below maximum level (assuming you chose an option to get a ton of XP), and all but your NORMAL ZAP and one (relatively weak) evil move work on him. Considering the sheer number of ways he can one hit you if you're at less than full health? Painful fight to say the least. Can take over an hour, not counting the inevitable dozens of retries.
* The end boss in ''[[Prototype 2 (Video Game)|Prototype 2]]'' has a bad case of this - he cycles between being immune to each of your five attack types without warning, and doesn't let the player fly around or consume lesser enemies in a game based on using mobility and, healing breaks and stealth.
* In the first ''[[StorySyphon Filter]]'', the [[Big Bad]] is mysteriously immune to all attacks except gas grenades; this may be a case of [[Story-Driven Invulnerability]]. Justified with the second boss, Girdeux, who wears full body armor, except for his [[Exploding Barrels|flamethrower tank]].
** The sequel's fully-armored final boss is immune to all weapons,. defeatingDefeating him requires using an auto-shotgun to knock him into a helicoptershelicopter's blades.
* The [[Ludicrous Gibs|Harmonic]] [[One Hit KO|Combos]] of ''[[Jade Empire]]'' don't work on boss characters.
* In the ''[[Kirby]]'' games, bosses and minibosses generally cannot be inhaled, because they're bigger than Kirby. MetaThe Knight,sole however,exception is aMeta little guy with cape and armorKnight, who is also immune, tobut is Kirby's abilitysize with a cape and armor. In the anime, Kirby tries to inhale him, but Meta Knight [[NoWon't Work On SellMe|just stands still]], saying that he has "special defenses".
* In the Post-Honkai Odyssey mode of ''[[Honkai Impact 3rd]]'', quest targets cannot be insta-killed by [[Back Stab]]s, but still take more damage than from any standard hit, though, so it's still a good idea to open with one.
 
== Video Games:= Fighter ===
* Happens in ''[[Soul Calibur]] III]]'' in some Quick Arena battles: sometimes the conditions for winning a match are such that normally powerful attacks become useless or not worth it. This happens even if the attack is known to do 90-100% damage most of the time (matches where an opponent must be bounced off a wall, hit with a soul charged attack, while taunting, etc etc.). In addition, [[Bonus Boss]] Night Terror is capable of flight and can't be defeated by a ring out.
** Likewise, in ''[[Soul Calibur]] IV]]'' it's not uncommon for bosses and tougher enemies to be equipped with the Auto -Grapple Break and Auto -Nullify Ringout skills.
* In ''Guilty Gear XX AC'', Youyou can't activate an instant kill move against the final boss, (believemuch me,as you'll want to.)
 
=== Video Games:First-Person Shooters ===
* ''Firestarter'' gave special abilities (aka Artifacts) that gave a significant boost. You couldn't use them during boss fights, but special abilities already in use (incuding one that slows all enemies) weren't stopped.
* In ''[[Heretic]]'' and ''[[Hexen]]'', if an attack would guarantee a one-hit kill or render the enemy as good as dead (such as by transforming them into something weak), boss monsters are either completely immune to it (in the case of special effects) or take a negligible amount of damage (in the case of literal one hit kills).
** On the subject of the engine, the {{spoiler|Icon of Sin}} of [[Doom]] 2 is outright invincible to every weapon except the rocket launcher. INCLUDING the [[BFG]]-9000. It is only that specific boss, though - you can kill the {{spoiler|Spider Mastermind}} in the original game at point blank with the BFG with one shot.
* In the first two ''[[Turok (Video Gameseries)|Turok]]'' games, the Nuke Weapon is useless against bosses. It can, however, be used to destroy Primagen's flyers at the end of ''Turok 2''.
* ''[[Deus Ex: Human Revolution (Video Game)|Deus Ex Human Revolution]]'': The bosses you have to kill usually can counter Takedowns. Jaron Namir is an exception, but only if you catch him immediately after he does a wall-mantle.
* Sanchez, the first boss-type enemy in ''[[Soldier of Fortune]] II'', is immune to bullets and can only be killed by electrocution.
 
=== Role-Playing Games ===
* ''[[Eternal Darkness]]'' really only has two true boss battles. The first is immune to bullets and impossible to reach with melee attacks and has to be killed by magic cast at just the right times. The second is mostly immune to everything, except assaults on his relic of power and attacks from spirits of those who came before. Until the very end, of course.
* Boss-type creatures in ''[[Albion]]'' are immune to most paralyzation and disintegration spells. There is one spell of each type that circumvents this immunity, potentially making the game [[Unwinnable]], as one of the bosses carries a [[Plot Coupon]] that gets disintegrated along as well. The last boss is immune to everything (except Steal Life and lightning based spells), but you don't have to actually beat it.
Line 34 ⟶ 67:
* In MMORPG ''[[City of Heroes]]'', Arch-Villains and Heroes (essentially big big bosses) have a system of resistances to controlling effects such as slows, stuns and immobilizes so high that they are all but immune. This presents a significant problem for characters who specialise in these effects, ranging from forcing them to game the system or use their secondary abilities, to making them outright powerless.
** This is referred to as the "Purple Triangles of Doom" because of the aura of purple triangles floating around the Archvillain's head. When they point up he has magnitude 50 protection against most status effects ''on top of'' the magnitude 6 protection that he would have as a normal Elite Boss. When the triangles point down, then he only has the magnitude 6 protection. This up and down cycle is not very obvious with all the other visual effects going on during battles, so usually nobody notices that they are down unless the Archvillain is suddenly locked in a Hold. For reference, your average status effect tossed around by the player will at most have a magnitude of 3.
* The vast majority of ''[[Final Fantasy]]'' bosses are immune to any form of instant death attacks, status effects, and [[Percent Damage Attack|Percent Damage Attacks]]s. There'll occasionally be one or two bosses in a game that the spells will work on, to reward players that [[Try Everything]], and there's frequently a slots combination that'll kill anything,<ref>many games feature an attack that functions as a slots minigame, with the effect depending on the combination. The "you win" combination is invariably obscenely difficult to get, and often screwing it up result in ''you'' losing.</ref>, though.
** Surprisingly, in the original ''[[Final Fantasy I (Video Game)|Final Fantasy I]]'', it is possible to defeat elemental fiend Tiamat simply by having a Black Wizard cast Break on her and [[Taken for Granite|turn her to stone]].
*** In addition, the final boss can be killed by casting Bane, a ''[[One-Hit Kill]]'' spell. It doesn't always work, although that's no problem since you can infinitely cast Bane using the Bane sword as an item.
** ''[[Final Fantasy IV (Video Game)|Final Fantasy IV]]'' has the Dark Elf, a challenging midgame boss, unless you cast Weak on him, which drops him to single digits. This weakness was removed in the remake.
** There's a glitch in early versions of ''[[Final Fantasy VI (Video Game)|Final Fantasy VI]]'' that can let you use instant death spells on bosses. There's still a boss vulnerable to X-Zone in recent versions, but he's supposed to be.
** Odin's Zantetsuken in ''[[Final Fantasy VIII (Video Game)|Final Fantasy VIII]]'' occurs randomly at a battle's start and will instantly kill the enemies unfortunate enough to get in its way, but when it occurs in a boss fight against Seifer, Odin himself gets killed.
*** In ''[[Final Fantasy V (Video Game)|Final Fantasy V]]'' and ''[[Final Fantasy VII (Video Game)|Final Fantasy VII]]'', Odin can be used to kill mooks instantly, but against bosses he will perform a powerful damaging move instead.
** On the other hand, ''[[Final Fantasy VIII (Video Game)|Final Fantasy VIII]]'' has Selphie's hard-to-perform [[Limit Break]] "The End" works on bosses, including the final boss Ultimecia. Also, the boss Abadon, being a zombie, can be killed simply by [[Revive Kills Zombie|tossing a Phoenix Down at it or casting Full-Life]].
** ''[[Final Fantasy X (Video Game)|Final Fantasy X]]'' gives us Yojimbo, who can perform [[One-Hit Kill|One Hit Kills]] on ''any'' enemy, be it random encounter, final boss (not that you need it), and all the bonus bosses with his Zanmato move. However, this requires either understanding a farcically complex mathematical formula, or giving him more than half your money.
* Geno Whirl of ''[[Super Mario RPG (Video Game)|Super Mario RPG]]'' does 9999 damage when done with a [[He Knows About Timed Hits|frame-precise timed hit]]. All enemies have less than that; the [[Final Boss]] has 8000 HP. Most bosses are immune to this attack, however, save for one.
* ''[[Adventure Quest (Video Game)|Adventure Quest]]'' made a [[Marathon Boss|marathon]] [[Bonus Boss]] immune to elemental-resistance-shuffling after someone figured out that they could use a class ability that dealt percentage-based fire damage, and the monster's 1275% energy weakness, to one hit kill an [[Eldritch Abomination]]. It dealt ''billions'' of damage.
** See also the ones that are immune to [[One-Hit Kill|Power Word Die]].
* In [[Mass Effect 3]]:
Line 54 ⟶ 87:
* The boss of ''[[Septerra Core]]'' was immune to insta-kill attacks and only flinched on high-power attacks. However, using the cloak spell prevented him from landing his one-hit party-kill attack against any party member.
* ''[[Shin Megami Tensei Nocturne]]'' contains 5 elements for inflicting stats aliments (mind, nerve, death, expel and curse). that can all inflict various standard stats effects all but 2 bosses (Forneus, who comes before the first instant death spell and Troll, who is weak enough to be a miniboss at most) are immune to death/expel and all but a handful of early bosses null or strongly resist the other 3. Most of the instant kill effects do work well on various [[Flunky Boss|flunkies]] however.
** ''[[Shin Megami Tensei (Franchise)|Shin Megami Tensei]]'' is unusual for a JRPG in that ''only'' bosses are outright immune to instant kills and incapacitating spells. All other enemies will be vulnerable to at least some of them, and in a good number of cases outright weak, translating to "one cast, one kill" against those types of enemies. As far as general gameplay is concerned, instakills are definitely NOT [[Useless Useful Spell|Useless Useful Spells]]s (Being [[Nintendo Hard|MegaTen]], simply "attack"ing a random counter is a good way to die). Also, stat debuffs definitely ''do'' work on bosses (and are seriously necessary in most cases).
** In ''[[Persona 3 (Video Game)|Persona 3]]'' and ''[[Persona 4 (Video Game)|Persona 4]]'', instant kill spells return as Light and Dark magic. Some enemies can block either or both elements, but every boss is immune. This hits no-one harder than poor Naoto in ''[[Persona 4 (Video Game)|Persona 4]]''. Naoto specialises in Light, Dark and Almighty magic, which is great for mowing down large numbers of [[Mook|Mooks]]s but utterly useless in boss fights.
** The day 7 boss in [[Devil Survivor 2]], Benetnasch, has a passive "Pacify Human".
* Bosses in ''[[World of Warcraft]]'' tend to be immune to incapacitating effects such as [[Baleful Polymorph|Polymorph]], [[Anti-Magic|Interrupt and silence effects]], and most notably stun effects. This is quite necessary, as if they weren't, every party would simply take as many rogues as possible to keep a boss stun-locked and incapable of doing anything. Similarly they're almost always immune to slow, to prevent them from being kited to death. There was a boss in ''The Burning Crusade'' whose movement speed was slow enough to allow kiting, and on heroic difficulty some people did indeed refrain from ever getting close to it.
** Bosses are almost always immune to silence, and some of their spells cannot be interrupted, though others can be, and indeed interrupting them can be necessary. Lady Deathwhisper's is a good example with her interruptable frostbolt of Kill the Tank. The game is helpful enough to provide a shield around the cast bar of uninterruptable spells so people don't waste an spell. A few spells also simply have a different effect on them (most notably the Deep Freeze spell of Frost Mages). And they are fully vulnerable to attacks or spells that can only be used on targets with low health or do more damage in that case. Those skills typically kill of a normal enemy right away, but against a boss they are still valuable, especially against the kind of boss that is [[Turns Red|the most difficult at low health]].
* Most bosses in the ''[[Dragon Quest (Video Game)|Dragon Quest]]'' series are immune to most or all status effects. Many of those that '''aren't''' immune to all of them can be made hugely easier by application of one they're not (For instance, a Troll King in ''[[Dragon Quest III (Video Game)|Dragon Quest III]]'' can be made trivial by silencing him so he can't cast his attack-buff spell), and virtually none are immune to effects that directly decrease their stats -- althoughstats—although a ''very'' rare few can nullify such effects after they're cast, for most bosses, these spells are outright essential -- andessential—and even for the ones that can nullify them, they have to waste a round doing so.
** For that matter, Random Encounter enemies are rarely, if ever, immune to status effects, and like in ''[[Shin Megami Tensei (Franchise)|Shin Megami Tensei]]'', some of these can be very difficult, such that simply going "attack, attack, attack" is little more than a way to get yourself killed.
* In ''[[Neverwinter Nights]],'' it shows the results of the in-game die rolls on the game journal. It gets rather annoying when you see "Player casts Hold Person. Boss attempts Will save. Fail!" while the boss continues to attack.
* In most ''[[Ys (Video Game)|Ys]]'' games, the [[Big Bad]] is immune to the [[Infinity+1 Sword]].
* In the ''[[Golden Sun (Video Game)|Golden Sun]]'' games, bosses seem to be immune because of how the Luck stat works: Luck increases a creature's chances to resist status effects. Since every boss in the game has a Luck stat of around 50 (or higher), their resistance to these effects is extremely high. Some of the Djinn attacks are able to bypass the resistance, though (mainly the ones that work like a Silence effect).
* Subverted in the rogue-like ''Ancient Domains of Mystery''. Many of the game's most difficult bosses can be rendered impotent if the player uses confusion, blindness, darkness, poison, or stun on them.
* The only way to truly get rid of a ''[[Nethack]]'' monster is to dispose of its corpse. The [[Horsemen of the Apocalypse|Riders]] {{spoiler|save for yourself when you start out spelunking}} have special coding that makes getting rid of their corpses nearly impossible and they are more than likely to revive under your disposal efforts. The Wizard of Yendor is similar as, after you have stolen a [[McGuffin]] from him, he will constantly revive no matter how many times he is killed and will make the remainder of your game miserable.
* Mostly averted in ''[[Xenoblade Chronicles]]'', where the only thing bosses are universally immune to is instant death.
* Subverted in ''[[Monster Girl Quest Paradox]]''. While bosses are more status-resistant than normal enemies, they never have blanket immunity to all status effects. Even [[Bonus Boss|Bonus Bosses]] are vulnerable to one or two, and many strategies for defeating them exploit this.
 
=== Shooters ===
== Video Games: Action ==
* Some games, usually on-rails shooters like ''[[Star Fox (Video Gameseries)|Star FoxFOX]]'', have area-effect attacks designed to destroy all on-screen enemies, but will only significantly damage bosses.
* It's very common for [[Bullet Hell]] shooters to have the [[Bonus Boss|Bonus Bosses]]es and/or [[True Final Boss|True Final Bosses]]es become invincible when the player bombs, taking no damage from the bomb or any of the players shots until the effect of the bomb ends. Generally, a barrier of some sort will be placed around the boss to show when this is occurring, although other things have been known to occur to indicate that the boss simply is not taking any damage (for example in ESP.Ra.De the boss literally leaves the screen). Sometimes the standard [[Final Boss]] gets this type of invincibility as well when they're on their [[Turns Red|final pattern]]. [[CAVE]] and [[Touhou Project]] games are prime examples of this.
* A few weapons in the [[PSPlayStation 2]] ''[[Ratchet and Clank]]'' games. The Zodiac and RYNOCIRATOR are one-hit weapons against normal opponents, but take off very little if any HP from bosses.
 
== Video Games:= Stealth ===
* In several ''[[Metroid]]'' games, there exists a "Speed Booster" item that acts as an instant kill to practicaly anything it touches. However, in ''[[Metroid Fusion]]'' {{spoiler|the SA-X}}, which was probably intended to be undefeatable, cannot be damaged by it (or by the derived ability called the Shinespark, which has the same effect on enemies as the Speed Booster).
* In ''[[Assassin's Creed II]]'' all generic enemies are vulnerable to your Hidden Blade (and in particular to being [[Counter Attack|counter]] [[One Hit KO|killed]]), but the penultimate and final boss are conveniently immune.
** Same thing with Screw Attack. It instakills normal enemies but doesn't work on any boss. It is not completely useless, but generally only causes very little damage to the boss and you take some damage yourself or it has to be very precisely aimed (in this cases, though, it does deal MASSIVE DAMAGE).
** Also played straight in ''[[Assassin's Creed: Brotherhood]]'': In addition to breaking free of grabs, the [[Kung Fu-Proof Mook|Kung Fu Proof Mooks]] and mini-bosses also can dodge or outright block counters; the final boss can as well. (There are two more story targets, but they're not so much bosses as "guys you have to kill without being detected, or mission failed.")
* Bosses in ''[[No More Heroes]]'' are completely immune to regular attacks, unless they are struck during specific times during their attacks.
* In ''[[Metal Gear Solid]]'', you can't break bosses' necks, nor can you slit their throats, and the KO is just minor incapacitation.
* In ''[[Cave Story (Video Game)|Cave Story]]'', [[Robot Girl|Curly Brace]]'s Air Tank generates a bubble shield that protects her from A) drowning and B) your Missile Launcher.
* The bosses of the [[Downloadable Content|DLC]] "special stages" in ''[[Mega Man 10 (Video Game)|Mega Man 10]]'' are completely immune to all of the secondary boss weapons (which you automatically receive when you begin the stage). Giving them no special weakness would have been one thing, but it's irritating that you can't even access those weapons' interesting attack patterns doing normal damage.
* The final boss in ''[[In Famous (Video Game)|In Famous]]'' has this in spades. On easy mode all your attacks work, and he can be beaten quickly, and on normal mode your strongest doesn't work, but he can still be killed easily. On the [[Nintendo Hard]] mode? At least one of your skills will be below maximum level (assuming you chose an option to get a ton of XP), and all but your NORMAL ZAP and one (relatively weak) evil move work on him. Considering the sheer number of ways he can one hit you if you're at less than full health? Painful fight to say the least. Can take over an hour, not counting the inevitable dozens of retries.
* The end boss in ''[[Prototype 2 (Video Game)|Prototype 2]]'' has a bad case of this - he cycles between being immune to each of your five attack types without warning, and doesn't let the player fly around or consume lesser enemies in a game based on using mobility and healing breaks and stealth
* In ''[[Syphon Filter]] 1'', the [[Big Bad]] is mysteriously immune to all attacks except gas grenades. Likely
[[Story Driven Invulnerability]]. Justified with the second boss, Girdeux, who wears full body armor, except for his [[Exploding Barrels|flamethrower tank]].
** The sequel's fully-armored final boss is immune to all weapons, defeating him requires using an auto-shotgun to knock him into a helicopters blades.
* The [[Ludicrous Gibs|Harmonic]] [[One Hit KO|Combos]] of ''[[Jade Empire]]'' don't work on boss characters.
* In the ''[[Kirby]]'' games, bosses and minibosses generally cannot be inhaled, because they're bigger than Kirby. Meta Knight, however, is a little guy with cape and armor who is also immune to Kirby's ability. In the anime, Kirby tries to inhale him, but Meta Knight [[No Sell|just stands still]], saying that he has "special defenses".
 
== Video Games: Fighter ==
 
* Happens in ''[[Soul Calibur]] III'' in some Quick Arena battles: sometimes the conditions for winning a match are such that normally powerful attacks become useless or not worth it. This happens even if the attack is known to do 90-100% damage most of the time (matches where an opponent must be bounced off a wall, hit with a soul charged attack, while taunting, etc etc).
** Also, [[Bonus Boss]] Night Terror can't be defeated by a ring out (He can fly).
** Likewise, in ''[[Soul Calibur]] IV'' it's not uncommon for bosses and tougher enemies to be equipped with the Auto Grapple Break and Auto Nullify Ringout skills.
* In ''Guilty Gear XX AC'', You can't activate an instant kill move against the final boss (believe me, you want to.)
 
== Video Games: FPS ==
 
* ''Firestarter'' gave special abilities (aka Artifacts) that gave a significant boost. You couldn't use them during boss fights, but special abilities already in use (incuding one that slows all enemies) weren't stopped.

It is only that specific boss, though - you can kill the {{spoiler|Spider Mastermind}} in the original game at point blank with the BFG with one shot.
* In the first two ''[[Turok (Video Game)|Turok]]'' games, the Nuke Weapon is useless against bosses. It can, however, be used to destroy Primagen's flyers at the end of ''Turok 2''.
* ''[[Deus Ex Human Revolution (Video Game)|Deus Ex Human Revolution]]'': The bosses you have to kill usually can counter Takedowns. Jaron Namir is an exception, but only if you catch him immediately after he does a wall-mantle.
* Sanchez, the first boss-type enemy in ''[[Soldier of Fortune]] II'', is immune to bullets and can only be killed by electrocution.
 
== Video Games: Strategy ==
 
== Video Games:= Strategy ===
* ''[[Command and& Conquer]]'' plays this straight; in the GDI campaign, you can't one shot the temple of Nod with the Ion Cannon. The rest of the series made sure you can't knock out the superweapon building or construction yard with only one superweapon attack, but the rest of the base used to power these weapons were fair game.
** ''Tiberian Sun's'' expansion ''Firestorm'' had a curious glitch in the last mission of the game. While a single [[Kill Sat|Ion Cannon]] blast won't destroy the mission objective, it can destroy the firestorm generator protecting it. Doing so bypasses the entire sidequest of having to capture the relay stations to shut the core off. In addition, while the Core Defender is resistant to all attacks, it was still programmed as a base land unit, so if you destroyed the bridge it was on while it was over water, it just dies due to the game not knowing what to do with a unit dropped into water.
* In the [[Turn -Based Strategy]] game ''[[Luminous Arc 2]]'', anyone that is equipped with the Auto-Medic Lapis is completely immune to status ailments. Most, if not all, bosses are equipped with Auto-Medic. The player can win Auto-Medic Lapis as well, allowing your characters to get in on the fun.
* [[Difficult but Awesome|Cyrus]] in the ''[[Dawn of War]] II'' campaign gains an ability to use [[Cold Sniper|his sniper rifle]] to instantly kill any infantry unit. While it makes sense that it doesn't work on vehicles or Monstrous creatures like [[Boss in Mook Clothing|Carnifexes]], it makes less sense that it doesn't work against bosses which are just more powerful infantry units (though it does do a lot more damage than his regular attack). Bosses are also immune to stun and knockback effects in the [[Dawn of War]] II campaign, making it impossible to disrupt them; this is removed in the expansion Chaos Rising, where most bosses, particularly infantry, can be stunned and knocked around at your leisure.
* The final four bosses in ''[[Fire Emblem Tellius (Video Game)|Fire Emblem: Radiant Dawn]]'' all come equipped with either the Nihil or Mantle skills, which prevents attacking units from using their own skills against the boss (and in Mantle's case, Critical Hits). This is mainly to prevent them from being quickly dispatched by the Mastery Skills, many of which can reach ridiculous amounts of damage when used by a high-level character with an SS weapon. The majority of other bosses are still vulnerable to them, however, and the player even gets a few Nihil scrolls of their own.
** Assassins, in the games that have the class, are able to randomly [[Single -Stroke Battle|kill their opponent instantly]], even if the attack would otherwise have dealt 0 damage. In the [[Fire Emblem Elibe|GBA]] [[Fire Emblem: theThe Sacred Stones|games]] everything but the final boss is fair game to be assassinated, but as of ''[[Fire Emblem Tellius|Path of Radiance]]'', all enemies classified as bosses have contracted the immunity.
* In ''[[Final Fantasy Tactics Advance (Video Game)|Final Fantasy Tactics Advance]]'', bosses and some leaders of enemy armies usually have ribbons marked by their names. Said ribbons make them immune to the ''laws'' that are constantly hounding your own characters (and any enemies without ribbons by their names). Characters who break the laws badly enough are carted off to jail - a "mission failed" scenario if it happens to main character Marche - and enemies without ribbons will never deliberately break the laws. But thanks to the ribbons, bosses can (and will) do anything they want without penalty.
 
== Video Games: Shooters ==
 
* Some games, usually on-rails shooters like ''[[Star Fox (Video Game)|Star Fox]]'', have area-effect attacks designed to destroy all on-screen enemies, but will only significantly damage bosses.
* It's very common for [[Bullet Hell]] shooters to have the [[Bonus Boss|Bonus Bosses]] and/or [[True Final Boss|True Final Bosses]] become invincible when the player bombs, taking no damage from the bomb or any of the players shots until the effect of the bomb ends. Generally, a barrier of some sort will be placed around the boss to show when this is occurring, although other things have been known to occur to indicate that the boss simply is not taking any damage (for example in ESP.Ra.De the boss literally leaves the screen). Sometimes the standard [[Final Boss]] gets this type of invincibility as well when they're on their [[Turns Red|final pattern]]. [[CAVE]] and [[Touhou Project]] games are prime examples of this.
* A few weapons in the [[PS 2]] ''[[Ratchet and Clank]]'' games. The Zodiac and RYNOCIRATOR are one-hit weapons against normal opponents, but take off very little if any HP from bosses.
 
== Video Games: Stealth ==
 
* In ''[[Assassin's Creed II]]'' all generic enemies are vulnerable to your Hidden Blade (and in particular to being [[Counter Attack|counter]] [[One Hit KO|killed]]), but the penultimate and final boss are conveniently immune.
** Also played straight in ''[[Assassin's Creed Brotherhood]]'': In addition to breaking free of grabs, the [[Kung Fu-Proof Mook|Kung Fu Proof Mooks]] and mini-bosses also can dodge or outright block counters; the final boss can as well. (There are two more story targets, but they're not so much bosses as "guys you have to kill without being detected, or mission failed.")
* In ''[[Metal Gear Solid]]'', you can't break bosses' necks, nor can you slit their throats, and the KO is just minor incapacitation.
