History WesternAnimation / YoungJustice

** "Revelation" featured [[GreenLantern Guy Gardner]], [[{{Icon}} Icon and Rocket]], PlasticMan and BlueDevil showing up to help the Justice League.

** EarlyBirdCameo: He appeared in the comics before the series was released.
** Also, "Revelation" marks the first animated appearance of MilestoneComics characters Rocket and Icon.

* BookcasePassage: Played very straight in ''Home Front''. Lampshaded no less:

** "Revelations" featured [[GreenLantern Guy Gardner]], [[{{Icon}} Icon and Rocket]], PlasticMan and BlueDevil showing up to help the Justice League.

** Artemis is placed in danger of drowning in the episodes "Home Front," "Alpha Male" and "Revelations," which aired one week after another. In each near-drowning she complains at how frequently it occurs, finally revealing that she now carries {{artificial gill}}s because of what has happened.
** In "Relevations" [[spoiler: The Helm of Nabu is used as a last resort in the battle against the Injustice League to allow Aqualad to become Dr. Fate. Kid Flash worried that Nabu would not let Aqualad free, as he had earlier threatened to do to Kid Flash]].

* GoryDiscretionShot: At the beginning of ''Alpha Males''.

* ItGotWorse: "Home Front" is basically one increasingly bad thing after another, culminating in [[spoiler: Red Tornado knocking out the team before going AWOL.]]

* MistakenIdentity: In ''Home Front'', Artemis hears Red Tornado call out her and Robin's code names and assumes he has come to save them from the bad guys. It turns out to be Red Torpedo, who has the exact same voice as Red Tornado.

** In "Home Front" Robin asks Kid Flash to give instructions for constructing an [=EMP=] device. The components Kid Flash mentions are actual electrical devices and can be used in the construction of such a device. The Vircator is a vacuum tube that can generate pulses of either X-rays or [=EMPs=], hence it being located in an x-ray machine, and Kid Flash's reference about it being a "stone" with a ten to the twelfth wattage is actually an accurate power level.

* TakingYouWithMe: In the climax of "Revelations," [[spoiler: TheJoker attempts to release his Joker venom and kill the Injustice League and the Justice League ''en masse'' after the Justice League arrives to apprehend him and the rest of the villains]].

-->'''Superboy:'''[[ImTakingHimHomeWithMe "Can I keep it?"]]

* TroubledFetalPosition: Artemis, towards the end of "Home Front," when facing the prospects of every friend she has dying and her being unable to do anything about it.
* TrueCompanions: Artemis says this to [[spoiler:her sister]]'s mask in "Home Front," calling the team her ''real'' family.

* TakingYouWithMe: In the climax of "Revelations," [[spoiler: TheJoker attempts to release his Joker venom and kill the Injustice League and the Justice Leagu ''en masse'' after the Justice League arrives to apprehend him and the rest of the villains]].

* ContinuityNod: "Denial" shows that Kid Flash actually has a room full of shelves where he keeps the 'souvenirs' he picks up every episode. There's a lot of empty space, so he clearly plans to continue his collecting.
** In "Relevations" [[spoiler: The helmet of fate is used as a last resort in the battle against the Injustice League and KF worried that Nabu wouldn't let Aqualad free. AL says Kent Nelson helped free him]].

* CrazyPrepared: After nearly drowning two missions in a row, Artemis begins carrying re-breathers on her person at all times.

* DiscOneFinalBoss: The Injustice League functions as one in-universe. The heroes believe they're the cause of all the events of the season up to "Revelations" but the audience knows it's the Light from early on.

* GodzillaThreshold: [[spoiler:No hope of winning left? Break out the Helmet of Fate.]]

* TheOtherDarrin: [[spoiler: In "Drop Zone", The Brain/L-6 was vocied by NolanNorth; in "Alpha Male", he was voiced by CoreyBurton.]]

* RunningGag: Usually each episode has one or two running gags throughout.

** Invoked in "Revelations," when Aqualad orders Robin and Miss Martian (who can camouflage herself) to "disappear." The camera pan shows that Robin has already obeyed.

** The sixteen-member Justice League has {{Hawkman}} and Hawkwoman, and two Green Lanterns (Hal Jordan and John Stewart), and a third Green Lantern, Guy Gardener, is later seen in "Revelation".

* TeamPet: The robo-sphere the team found in Bialya.

** Later, the giant wolf in India.

* WouldHitAGirl: All over the place. Male villains against female heroes and male heroes against female villains.
** Notably, Aqualad knocking out Killer Frost by clubbing her with a water weapon [[HoistByHisOwnPetard that she froze]], Superboy taking out killer Frost and a super-strong girl Frost was working with in the span of a few seconds, and anyone on the team attacking Poison Ivy (not always successfully) when they got a shot in ''Revelations''.

* ArtificialGill: One of the many things Robin (and likely Batman by extension) has in his UtilityBelt.

* "Revelations" featured [[GreenLantern Guy Gardner]], [[{{Icon}} Icon and Rocket]], PlasticMan and BlueDevil showing up to help the Justice League.

** Superboys' hatred of monkeys.

--> In "Relevations" [[spoiler: The helmet of fate is used as a last resort in the battle against the Injustice League and KF worried that Nabu wouldn't let Aqualad free. AL says Kent Nelson helped free him]].

* In "Relevations" [[spoiler: The helmet of fate is used as a last resort in the battle against the Injustice League and KF worried that Nabu wouldn't let Aqualad free. AL says Kent Nelson helped free him]].

** The sixteen-member Justice League has {{Hawkman}} and Hawkwoman, and two Green Lanterns (Hal Jordan and John Stewart).

** This line from "Revelation" actually made more than one Troper search for the "Radar' section of Young Justice right in the middle of the episode:

---> '''Aqualad''': (responding with) Then we will make our our own fun.

---> '''Aqualad''': (responding with) Then we shall make it fun.

* TheAlcatraz: Belle Reve, a supervillain penitentiary run by Amanda Waller, [[BadassBoast strong enough to contain Superman himself]]. They checked. [[spoiler: At the end of "Terrors" it falls under the control of the Light, who ferment an escape plot in order to remove Waller as warden and replace her with Dr. Hugo Strange, one of their agents.]]

** This line from "Revelation" actually made this Troper search for the "Radar' section of Young Justice right in the middle of the episode:
---> '''Artemis''': Ugh... I feel naked... and not in the good way.

---> '''Arrowette''': Ugh... I feel naked... and not in the good way.
