History Recap / JusticeLeagueUnlimitedS1E10DarkHeart

* AIIsACrapshoot: Subverted. The Dark Heart does exactly what it was programmed to do: replicate itself, consuming matter until it devours entire planets in the process. And because [[AbusivePrecursors the civilization]] that built it [[HoistByTheirOwnPetard were destroyed by their own creation]] long ago, it doesn't realize it's primary directive has long become obsolete.

* {{BFG}}: This is the first time that the League break out the '''[[LampshadeHanging B]]'''[[FunWithAcronyms inary]] '''[[KillSat F]]'''[[FunWithAcronyms usion]] '''[[SwordOfDamocles G]]'''[[FunWithAcronyms enerator]], described as packing enough force as a nuclear warhead, to slow down the advance of the nanomachine robots. The bad news: It uses the entire power of the Watchtower, which reboots its system in an hour after usage. Even worse news: [[TheWorfBarrage It does very little to slow them down]].

* ZergRush: The individual units the Dark Heart spawns are destroyed quite easily, with even the [[BadassNormal unpowered]] members of the Justice League shown wiping them out en masse, but that doesn't matter when the machine will quite literally keep respawning them endlessly until the entire planet has been consumed. As the invasion continues, it's even shown to have begun making giant sized versions of it's troops that are powerful enough ''individually'' that heavy hitters like Superman and Wonder Woman start struggling to fight them.

* HopeSpot: Martian Manhunter uses the Watchtower's satellite cannon to dig a deep trench around the nanomachine blob in an attempt to at least slow it down. Unfortunately, it somehow manages to RESTORE the trench to solid ground again, like it was never there.

* AIIsACrapshoot: Subverted. The Dark Heart does exactly what it was programmed to do: replicate itself, and consume matter until it devours entire planets. It's only because [[AbusivePrecursors the civilization]] [[HoistByTheirOwnPetard were destroyed by their own creation]], that it doesn't realise that the war that they were designed for is long over.

* AbusivePrecursors: The Dark Heart was part of a series of war machines created for a conflict, initially assumed to be interplanetary, but was more likely interstellar (at the very least), that would eventually eradicate planets of the opposing side, and move on to the next. The conflict occurred around 50,000 years ago and by then, it had likely destroyed the civilization that created them - one of the probes arrivals on Earth, was more coincidental than deliberate.

-->'''Superman:''' We should be arriving soon. How's the trench holding up?
-->'''Batman:''' What trench?
--> (''Complete with WhamShot of nanomachine robots advancing having already reached ground level'')

* TwoVoicesOneCharacter: Superman's last line "we are" is provided by Kevin Conroy for some reason.

* ApocalypseHow: ApocalypseHow/ClassX, at the very least. Perhaps even [[ApocalypseHow/ClassX2 Class X-2]] going by what the Atom sas about it.

* TheWorfEffect: To drive home the threat of the Dark Heart, the might of ''the entire Justice League'' isn't enough to stop it.

* GodzillaThreshold: The Dark Heart pushes Martian Manhunter to declare a threat level of "Omega": Meaning ''sending every single superhero in the Justice League'' onsite to deal with it. They barely contain it, and given the amount of {{Badass Normal}}s on the team, [[EverybodyLives they are very lucky not to have received fatalities]]. To put it in perspective: only the threats of Amazo and Darkseid would prompt a similar response.

--> (''Complete with WhamShot of nanomachine robots advancing having already reached ground level'')

* GettingCrapPastTheRadar: When Wonder Woman puts Atom between her cleavage, she says "I need both hands professor Palmer". She obviously meant it as "Keep your hands to yourself and don't make a big deal out of this".

--> '''Atom''': Show him something that destroyed its creators and everything around it, and he wants to play with it...

* AIIsACrapshoot: Subverted. The Dark Heart did what it was programmed to do: replicate itself, and consume matter until it devours entire planets. It's only because [[AbusivePrecursors the civilization]], were as with the case with such destructive technology, [[HoistByTheirOwnPetard were destroyed by their own creation]], that it doesn't realise that the war that they were designed for is long over.

* ApocalypseHow: ApocalypseHow/ClassX, at the very least. Perhaps even [[ApocalypseHow/ClassX2 Class X-2]] going by what the Atom said about it.

* HopelessWar: No matter how many robots the League and the Army destroy, more would instantly take their place.

* TheJuggernaut: The Dark Heart was practically unstoppable. Even the full might of [[HeroesUnlimited the entire Justice League]] could barely slow it down. Only the Atom shutting down the central core, by giving it the equivalent of a heart attack, shut it down.
* MookMaker: The namomachine blob releases hundreds of separate machine creatures/drones to consume everything in sight, even the surface. The more the drones are destroyed, the more they the creatures/drones, this time larger and stronger are released from the hub.

* {{Nanomachines}}

* ThisLooksLikeAJobForAquaman: The Atom, who in an earlier episode was described as the League's weakest member by Luthor, is the right man for the task of stopping the Dark Heart; having an expertise on nanotechnology and his ability to shrink into microscopic size, he found the Dark Heart's weakness, damaged its 'central power core', and shut it down - saving the world.
* TooDumbToLive: General Eiling takes most of the killer robots back for study once the battle was won, saying that it "may prove useful as it almost defeated the Justice League". Atom summed it up well.

* VictoriasSecretCompartment: Wonder Woman placed a miniaturized Atom down her cleavage so she could use both her hands to fight the robots.

--> Atom: "Show him something that destroyed its creators and everything around it, and he wants to play with it..."

* MsFanservice/MostCommonSuperPower: Wonder Woman, who has some very buxom breasts. This is {{lampshaded}} when the Atom gets a ride to the fight in Wonder Woman's cleavage.

* ApocalypseHow: [[ApocalypseHow/Class X Class X]], at the very least. Perhaps even [[ApocalypseHow/ClassX2 Class X-2]] going by what the Atom said about it.
