** It knew about the translation error that tells you to only attack when it's in that form.

This is a specific form of HoistByHisOwnPetard - the boss only has to avoid one particular action to be literally invincible. Since it involves the boss intentionally leaving themselves open, it also heavily involves carrying the VillainBall. Finally, FridgeLogic heavily comes into play - it's usually in retrospect that you realise WhatAnIdiot the boss in question is for continuing to perform the attack even after it's been exploited several times.

* Almost all of the bosses in BillyHatcherAndTheGiantEgg do this, with most of the bosses all you have to do is dodge everything until they mess up and become vulnerable, sometimes the bosses do the dumbest things to allow them to be harmed and still repeat their actions ''over and over again'', which makes them seem stupid even though [[ThatOneBoss they may be owning you.]]

* In the TeenageMutantNinjaTurtles game ''TurtlesInTime'', the stage four boss is Shredder himself manning a gun turret. The turtles can't hurt the turret directly; they have to throw Foot solders at it. If Shredder stopped sending soldiers in, he would have all the time in the world to pick the turtles off with his guns.

** ''EVERYBODY'' in ''{{Punch-Out}}'' would have a better chance against Little Mac if they didn't have tells, stop to taunt, etc.

** A LOT of bosses that do this: King Dodongo (keep rolling, don't spit fire), Ganondorf (almost every single fight, he shoots an energy ball that you two end up smacking back and forth; spam your un-reflectable powers), Molgera (dude.... seriously? Sticking your tongue out and just sitting there?), and others that I'm blanking on right now.

* Two of the BonusBosses in the flash RPG ''Sonny'' do this. Omen has a move that makes both his next attack and yours much more deadly; if you already have a shield in place, you can hit him ForMassiveDamage while absorbing his attack. Dr. Herregods is even more egregious; he has [[OverNineThousand one million hit points]], and once you've knocked off a thousand or so he will heal himself for ''two million'' hit points. [[spoiler: Too bad you have a move that converts damage to healing and vice versa.]]

* If only the [[StarWars The Death Star]] plumbers had put a U-bend in the exhaust port...

** ''SuperMarioBros2'': Wart opens his mouth so you can feed him veggies that kill him.
*** Somewhat justified, because he needs to open his mouth so that he can use his ''own'' attack on Mario.
**** However that is the definition of the trope, a move which the boss does to attack that makes him vulnerable.
**** Not really. It's his only attack, so he doesn't really have any other options, unless he wants to just sit and wait for Mario to get bored and leave.
**** Is there a good reason he couldn't have done that?
** ''SuperMarioBros3'': Bowser will ground pound his way into the bottomless pit in his throne room.

*** As I understood it, Metroid Prime wasn't necessarily attacking you with Phazon per se, so much as secreting it as a byproduct of its energy output. Basically you were taking advantage of its PottyFailure.
*** Phantoon may not be able to stay phased permanently - it may be like how whales have to surface every so often to breathe; they'd never get harpooned if they just stayed deep underwater, but it isn't possible.

*** Except the question is begged as to why he has a [[BossArenaIdiocy vegetable-making machine in his room in the first place.]]

**** Because it's the Dream Machine, the device that created the dream world, which Wart captured and put to use to create the nightmare creatures and bosses he uses to conquer and rule. Unfortunately, the machine is also sentient, and aids Mario and Company in the battle with Wart.
