Line #68 Main/BossVulnerability


1	{{Boss Battle}}s in video games can require a wide variety of strategies and tactics to defeat. However, how vulnerable they are to the player characters' attacks tends to vary from game to game. There are generally four types of boss vulnerability:
2
3	* '''Always Vulnerable:''' The boss is susceptible to damage at all times, and usually attacks relentlessly. This type can be difficult due to the fact that the player must concentrate on both avoiding the boss' attacks and hurting the boss at the same time.
4	** May be a DamageSpongeBoss or perhaps a RushBoss. May or may not receive MercyInvincibility when you hit it, depending on the genre.
5	** A ShieldedCoreBoss typically falls under this trope; if it drops its shield of its own volition it may also class itself under "Wait Them Out" with elements of a TacticalSuicideBoss.
6	* '''Wait Them Out:''' The boss cannot be harmed by any means until a certain amount of time has passed or a certain action is performed, at which point they will become vulnerable for a short period of time. This type can be easier due to the fact that you only have to concentrate on survival, and not have to balance offense and defense. However, it can be annoying if you miss the window of opportunity, since you will have to go through the attack pattern again before getting a chance at another shot.
7	** AttackItsWeakPoint and TacticalSuicideBoss are common tropes for this type.
8	** HoldTheLine may be involved if exposing the vulnerability is time-based.
9	* '''Mixed:''' A mix of the above. The boss is technically vulnerable at all times, but can become stunned or otherwise more susceptible to the player character's attacks. This may happen after a certain time has elapsed, or a special action or actions may be required.
10	** A BarrierChangeBoss may classify under this or the "Wait Them Out" variety, but that depends on the player's ability to attack its weakness or the conditions that trigger the barrier change.
11	* '''Miscellaneous:''' Any boss that doesn't fit into any of the above categories. These are likely to be SheatheYourSword battles, {{Puzzle Boss}}es, or some other type of atypical battle.

13	A SubTrope of BossBattle. Bosses that are ''never'' vulnerable are a HopelessBossFight.

15	!!Examples:
16
17	[[AC:Always Vulnerable]]
18	%%* ''Franchise/{{Castlevania}}'': Most bosses.
19	%%* ''VideoGame/DistortedTravesty''.
20	* ''VideoGame/{{Iji}}'': Every boss is always vulnerable, except for [[spoiler:Iosa]]'s second form (wait it out) and the {{final boss}} (mixed). However, if you don't have any big guns, Proxima and the final boss become full Wait Them Out examples.
21	* Most bosses in the ''Franchise/KingdomHearts'' series are either this or mixed.
22	%%* ''VideoGame/HeroCore'': Most bosses.
23	%%* ''VideoGame/{{Metroid}}'': Ridley and Mother Brain.
24	%%* ''VideoGame/DevilMayCry'':
25	* ''VideoGame/EternalDaughter'': Every boss except for the final one, which must be waited out. The FinalBoss requires you to go through a short but difficult series of actions in order to make him vulnerable, at which point you can hit him once before having to make him vulnerable again. [[MarathonBoss It's a long fight]].
26	%%* ''VideoGame/LaMulana'': Most bosses.
27	%%* ''VideoGame/CaveStory'': Most bosses.
28	* ''VideoGame/MegaManClassic'': The most common boss type. Almost every boss falls into this, and the ones that don't usually need to be waited out.
29	%%* ''VideoGame/TheLegendOfZeldaSpiritTracks'': The second phase of the fight with Skeldritch.
30	%%* ''VideoGame/TheLegendOfZeldaBreathOfTheWild'': The Blights and most overworld bosses.%%Are examples how?%%[[SandWorm Molduga]] is an exception to this though.%%How?
31	* ''VideoGame/TransformersWarForCybertron'': Both Omega Supreme's and Trypticon's first phase. The former constantly attacks while you're trying to destroy all of his turrets, and the latter unleashes a near non-stop swath of destruction while the player has to time shooting power cells next to his weapon systems to overheat them.
32	* ''Franchise/SonicTheHedgehog'': Most bosses in 2D games are always vulnerable (with a few exceptions) but either can't be reached immediately, or are protected by their attacks. Usually it's not safe to try attacking, and is better to wait them out.
33	* ''VideoGame/ChimeraBeast'': In contrast to [[AttackItsWeakPoint the other bosses]], the lion-boar mammal is fully vulnerable.
34	* ''VideoGame/GriefSyndrome'': Most [[EldritchAbomination Witches]] blur the line, but fall on this side by being ''almost'' always attackable. [[GardenOfEvil Gertrud]] and [[SandWorm Charlotte]] have jumping attacks which take them off the screen, but otherwise can always be hit. [[DoppelgangerSpin Kirsten]] switches places with her decoys fairly regularly, but can always be hit when she isn't in that animation. [[CastingAShadow Elsa Maria]] goes underground to move, but comes right back up.
35	* ''VideoGame/DemonsSouls'', ''VideoGame/DarkSouls'' (and its sequels), and ''VideoGame/{{Bloodborne}}'': Most bosses work like this, though quite a few have [[AttackItsWeakpoint spots where attacks will do more damage]].
36	* ''VideoGame/{{Cuphead}}'': Most of the bosses are constantly vulnerable; the difficulty lies in continuing to attack their hitbox while dodging their attacks.
37
38	[[AC:Wait Them Out]]
39	* ''VideoGame/{{Hexen}}'': The Heresiarch casts a barrier spell that makes him invulnerable and reflects most attacks. While two classes have an attack that can pierce the barrier, Baratus (the fighter) does not.
40	%%* ''Franchise/SuperMarioBros'': Most bosses.
41	* ''VideoGame/AnUntitledStory''.
42	%%* ''VideoGame/HeroCore'': The Liquid Metal Processor and the final form of the [[FinalBoss Cruiser Tetron]].
43	* ''VideoGame/FinalFantasy'':
44	** ''VideoGame/FinalFantasyIV'': The first boss, the Mist Dragon, can only be attacked when it is not in its mist form (the game tells you this, after you get hit with a nasty ice attack, if you try). This is copied by Wingraptor in ''VideoGame/FinalFantasyV'', [=Ymir/Whelk=] in ''VideoGame/FinalFantasyVI'', and Guard Scorpion in ''VideoGame/FinalFantasyVII''. Like Mist Dragon, each of them serves as both first boss, and tutorial for the realtime battle system.
45	** ''VideoGame/FinalFantasyXIII'' has a few bosses (and regular enemies) that are practically invulnerable until they are [[BreakMeter staggered]]. However, after you max out the crystarium, many of the [[OptionalBoss mission marks]] go down faster if you just go all out instead of trying to work out a stagger.
46	%%* ''VideoGame/{{Metroid}}'': Most bosses.
47	* ''VideoGame/TheSpiritEngine2'':
48	** The Cloud Child has a separate life bar that acts as a shield. Once you reduce it to zero, the cloud child will be stunned until the shield regenerates to full, during which you can attack its main life bar.
49	** The first form of the FinalBoss is invincible until a certain amount of time has passed. Its second and third forms are also difficult to damage until you destroy at least one of its [[FlunkyBoss flunkies]], since they'll block your hits otherwise.
50	%%* ''VideoGame/LyleInCubeSector'': Every boss, except for the semifinal one, which is always vulnerable.
51	%%* ''VideoGame/EternalDaughter'': The FinalBoss.
52	* ''VideoGame/Persona4'': Shadow Rise cannot be damaged, but halfway through the fight, she leaves and you end up fighting Shadow Teddie instead.
53	* ''VideoGame/PokemonLegendsArceus'': By default, the Noble Pokémon's frenzies cannot be diminished -- throwing balms at them deals scratch damage at best, and Avalugg in particular spends most of its battle too far away from the player character to be hit. Instead, the player needs to wait for them to exhaust themselves after performing their biggest attack, throw a Pokémon at them to battle, defeat them, and then exploit a brief ensuing window of vulnerability to throw balms and chip away at as much of their frenzy meter as possible before the cycle resets.
54	%%* ''Franchise/SonicTheHedgehog'': Most bosses in the 3D games, as well as those in the ''VideoGame/SonicRush'' series, though there are a few bosses that subvert it.%%ZCE. How are these examples?
55	* ''VideoGame/IWannaBeTheGuy'': Most, although some sections and bosses are Type 1. Thankfully, their vulnerable sections tend to be frequent.
56	* ''Franchise/MegaMan'': A few bosses fall into this category, notably ones that can fly out of your reach such as Gyro Man in ''VideoGame/MegaMan5'' (unless you have Gravity Hold).
57	* ''VideoGame/ValkyriaChronicles'': The Batomys is only vulnerable the round immediately after it's fired its main cannon and exposes its radiators to cool down.
58	* ''Franchise/TheLegendOfZelda'': Most bosses are this, with most of the exceptions being in the [[VideoGame/TheLegendOfZeldaI first]] [[VideoGame/ZeldaIITheAdventureOfLink two]] games (and the aforementioned Skeldritch round 2), which are always vulnerable. Typically, you have to use the item you just got in the current dungeon to make the boss vulnerable to your sword.
59	* ''VideoGame/TransformersWarForCybertron'': Both Omega Supreme and Trypticon's second phases. For Omega Supreme, you need to stay alive until a power cell comes up from the ground, then corrupt it (and, thus, him) with Dark Energon before he can be hurt. With Trypticon, you need to wait out his bombardment and the Dark Energon parasites until Trypticon exposes the heat vents in his chest.
60	* ''VideoGame/ChimeraBeast'' has three. The first boss (two lamprey things) are only vulnerable when they expose their heads to attack, the third (a GiantFlyer) can only be damaged when it opens its mouth to attack, and the fourth (an alien croc) can only be harmed when his head is out of the water ''and'' his mouth is open.
61	* ''VideoGame/GriefSyndrome'': The two hardest bosses get a bit of FakeDifficulty from this. [[FinalBoss Walpurgis Night]] has three phases most of the time (with a fourth KaizoTrap phase before the final vulnerable phase), and she is only vulnerable during one of these phases. [[OptionalBoss Oktavia von Sekendorf]] likes to pull a DoppelgangerSpin which makes her nigh-impossible to hit when she's ''not'' attacking, and fades into the background for one of her attacks.
62	* ''VideoGame/DonkeyKongCountry'': King K. Rool is often this, as are a few other bosses where you have to wait for barrels to be dropped first before you can attack. Boss Dumb Drum is this taken to its extreme; you don't actually attack him at all, you should wait out his attacks until he eventually explodes (except in the GBA version, where he just acts like other examples of this boss type).
63	* ''VideoGame/SuperMarioWorld'': This is a fairly common setup for bosses in [[GameMod ROM hacks]].
64	** ''VideoGame/BrutalMario'': Almost every boss works this way, to the point some hackers call such boss 'carol bosses', after the name of ''Brutal Mario''[='=]s creator.
65	** ''VideoGame/ScarletDevilMario'': Most bosses are like this, with the player having to wait until they generate a Goomba or Koopa to be able to hurt them.
66	** ''VideoGame/ASPEMario'': The final boss, some of the ''VIP'' series bosses, and most fights in ''Super Mario LD'' are also like this, with the player only being able to damage the boss when it drops a random throw block after every three or four attacks.
67	* ''VideoGame/LegoMarvelSuperHeroes2'': Bosses often have invulnerability periods, represented by a lock over their LifeMeter. Either the player(s) must wait for a moment to attack, or it's a FlunkyBoss whose mooks must be taken out first.
68
69	[[AC:Mixed]]
70	* ''Franchise/KingdomHearts'': Most bosses in the series are either this or always vulnerable.
71	* ''VideoGame/{{Iji}}'': The FinalBoss is ''technically'' vulnerable to most of your weapons, though even the [[InfinityMinusOneSword MPFB Devastator]] is not going to get you very far. The most effective way to injure him is to wait out his attacks until he uses a powerful ChargedAttack, then [[TennisBoss reflect it back at him]].
72	* ''Videogame/CrashBandicoot1996'': Pinstripe Potoro is a mix. He's vulnerable at any point when not firing his gun (and technically vulnerable before then but you'd get torn to pieces trying), but only for the first three of six hits. For the last three, he becomes invincible, and you have to wait for his gun to jam.
73	* ''Franchise/DotHack'': [[spoiler:Corbenik]]. [[spoiler:Despite having glitched/"infinite" HP, your attacks still deal normal damage. In reality, all three of its forms have 7000 HP. The second one will put up Ultimate Defense partway through the battle, which makes him invincible until the plot kicks in.]]
74	* ''VideoGame/TheLegendOfZeldaSkywardSword'': Ghirahim. While he's not exactly immune to any of your attacks, he's a master swordsman and can easily block slow or sloppy attacks. You'll have to be smart about how you swing your Wiimote in order to get past his defenses. This gets subverted somewhat for your final battle with Ghirahim; the first phase is a RingOutBoss, while the second phase is type 2.
75	* ''VideoGame/ViewtifulJoe'': Some bosses are vulnerable at all times (usually early bosses), some are only vulnerable after certain conditions (such as Fire Leo), and some are perpetually vulnerable but can be stunned for a longer combination of attacks.
76	* ''VideoGame/Persona3 FES: The Answer'': The FinalBoss normally has a decent amount of defense, but after stopping its "Dark Embrace" attack, it will be unable to move for a turn. During this turn, it will take ''much'' more damage from anything.
77	* ''VideoGame/ShadowWarrior2013'': The bosses tend toward this. The glowing parts of their armor need to be hammered with gunfire until the Ki Line is exposed in order to destroy that part of the armor. Destroying all of the armor destroys the boss.
78	* ''VideoGame/CognitiveDissonance'': [[FinalBoss Giygas]] is technically Always Vulnerable, but has such astronomically high defense that even with the game allowing your attacks to actually reduce his HP (unlike in ''VideoGame/EarthBoundBeginnings'' or ''VideoGame/EarthBound1994''), [[PuzzleBoss it's functionally impossible to beat him with brute force alone]]. There are five ways to end the fight with some semblance of victory, all of which require the fight to progress to the point where Gieuge, the boss's previous form, goes OneWingedAngel, and which method is used determines [[MultipleEndings the ending]] the player receives. Without spoiling any details of the endings, the ways to win are:
79	** Normal Ending: Lose to Giygas; [[HoldTheLine progressing the battle this far]] is considered a sufficient victory by the plot, [[spoiler:even though all of the protagonists die]].
80	** Good Ending: Use PK Harmony to calm Giygas down and [[spoiler:restore Gieuge]], cutting the fight short without either side perishing.
81	** Secret Ending: Use Nightmare Empower to debuff Giygas's defense to manageable levels and whittle down his HP the old-fashioned way. This leads to an extra chapter instead of immediately ending the game.
82	** Paradox Ending: Use Song on Giygas, cutting the fight short and initiating [[TrueFinalBoss an alternative boss fight]] which is Always Vulnerable.
83	** Joke Ending: Use the ballpeen hammer to [[ArmorPiercingAttack ignore Giygas's defense stat entirely]] and whittle down his HP the old-fashioned way.
84	* ''VideoGame/MetroidDread'': The final boss has three phases that uses a mixture of always vulnerable and waiting it out. The first phase has an energy shield that renders him completely immune to damage until he's parried, but you have to wait for an attack to parry. The shield initially takes damage until it turns from blue to red, but if the first phase lasts long enough he activates an orange shield that blocks everything, forcing you to dodge and wait. The second and third phases have the boss always open to attack, but he's also constantly attacking Samus, requiring you to dodge attacks while attacking back when given the chance.
85
86	[[AC:Miscellaneous]]
87	* ''VideoGame/{{Portal}}'': [[spoiler:[=GLaDOS=]]], who is also a PuzzleBoss. [[spoiler: The rocket turret to hit [=GLaDOS=] with is only active while there's a core to detach.]]
88	%%* ''VideoGame/FinalFantasyIV'': [[spoiler:Dark Cecil]]. Kind of a given, since it's the TropeNamer for SheatheYourSword.
89	* ''VideoGame/HalfLife1'':
90	** The tentacles. They are a PuzzleBoss immune to weapons that takes some running and turning on fuel and electricity to defeat.
91	** Same for the Gargantua, though it is vulnerable to explosives and energy weapons. The first time it is encountered though, the players arsenal is most likely insufficient to defeat it.
92	* Every Phase [[spoiler:except Corbenik, which is mixed instead]] in Project Franchise/DotHack. The bosses take damage just fine — their HP count is just glitched up, making them undefeatable. Data Draining them fixes this and also causes them to lose a lot of their special attacks, including their own Data Drain.
93	* ''VideoGame/DarkChronicle'': A rather odd variation. The TrueFinalBoss, [[spoiler:Dark Element]], changes its color between red and blue every so often during your fight. When it's red, only Max can hurt it. When it's blue, only Monica can hurt it. Unfortunately, it's never vulnerable to the Ridepod or its [[GameBreaker Nova Cannon]].
94	* ''VideoGame/HeroCore'': The Grand Mother is a bit of an odd example. It's completely invincible until you destroy its flunkies a few times, at which point it [[TurnsRed goes berserk]] and loses its invincibility entirely.
