** Additionally, an alien invasion is also how the Justice League was first formed in the comics and has been used in subsequent adaptations, like in the ''WesternAnimation/JusticeLeague'' cartoon, ''WesternAnimation/YoungJustice2010'' cartoon, ''WesternAnimation/JusticeLeagueWar'', and the [[Film/JusticeLeague live]][[Film/ZackSnydersJusticeLeague -action]] ''Justice League'' films.

''RWBY/Justice League'' is a 2021 Creator/DCComics limited series, featuring a crossover between ''WebAnimation/{{RWBY}}'' and the ''Franchise/{{Justice League|OfAmerica}}''.

Set in the world of Remnant, Team RWBY encounters mysterious warriors in their fight against the Grimm. Ruby and Yang team up with [[Franchise/{{Superman}} a local farmboy]] to take down a new type of Grimm set loose on their home island of Patch, while on Menagerie, Blake meets [[Franchise/WonderWoman an enigmatic woman who seems out of touch with the current times]], and in Atlas, Weiss meets [[Franchise/{{Batman}} a brooding, troubled heir]].

** Franchise/{{Batman}}, Franchise/TheFlash, Jessie Quick and Franchise/{{Aquaman}}'s ''RWBY'' counterparts are [[BeastMan Faunus]], with Bruce being a bat faunus, Barry being a turtle faunus, Jessie as a fox faunus, and Arthur being a shark faunus.

During RTX 2022, an animated adaptation, titled ''WesternAnimation/JusticeLeagueXRWBYSuperHeroesAndHuntsmen'', was [[https://twitter.com/officialrwby/status/1542936943562035203?s=21&t=Ap-LBWGzY1IGVWwNsrFz1g announced]] to be in development by Creator/RoosterTeeth and Creator/WarnerBrosAnimation for a DTV release in 2023. It is also [[https://twitter.com/laurayates/status/1558114563106770944?cxt=HHwWgMC81ZO8xJ8rAAAA announced]] that the feature film will be split into two parts and serve as the second DTV movie to use CGI following ''WesternAnimation/BatmanAndSupermanBattleOfTheSuperSons''. The storyline, while adapting several elements from the comic, instead has the two done in a more traditional crossover with the Justice League being pulled from their universe and de-aged. The first part will be available to purchase digitally and on Blu-ray on April 25, 2023.

** Official art for Jessica shows that her power ring still uses HardLight here, as Velvet's Anesidora had previously demonstrated use of weaponized hard light at the end of Volume 3. [[spoiler:Issue 9 reveals that while the power ring is Hard Light, it's ''still'' a GreenLanternRing and not a ''RWBY''-themed creation.]]

* AdaptationalDeviation: Bruce, a charismatic playboy in most depictions, is seen as a black mark among other upper-class Atlesians for being a Faunus.

* HeatVision: Clark has this in classic fashion, using it to start a campfire.

* AllTheOtherReindeer: Clark makes vague mention of having previously frightened people with his powers, while Bruce is barely tolerated by Atlas high society because of his Faunus heritage.

* AnAxeToGrind: Bruce's weapon is a large battle-axe with bat-shaped blades that his guardian, most likely Alfred, purchased for him.

* TurtlePower: Barry Allen turns out to be a ''Tortoise'' Faunus, of all things. He even wears a backpack that looks like a turtle shell, and has scales visible on his elbows.

* OutOfFocus: Despite taking place between Volume 2 and 3, almost nothing from the show's story is brought up, and barely any characters outside of Team RWBY appear, much less have a major role, all in favor of the comic focusing on Team RWBY meeting and working together with the Justice League. This is handwaved away in-universe as the mysterious threat causing the disappearances of Huntsmen throughout Remnant.

* ForWantOfANail: [[spoiler:Bruce seems to believe that Starro's arrival lead to their births, suggesting that if Jessica caught him earlier, they wouldn't be here.]]

* AgeLift: The Justice Leaguers are shown as teenagers, with Clark and Bruce being around Team RWBY's ages and Blake saying that Diana doesn't look to be any older than her.

* SparedByTheAdaptation: The mainstream Nora Allen was murdered by Professor Zoom, her Remnant counterpart is alive and well. That said, this is TruerToTheText as far as her status pre-''The Flash: Rebirth'' is concerned, where she and Henry lived to see Barry grow up and become the Flash and said murder was, in fact, said a CosmicRetcon (the Cobalt Blue arc establishing Barry's parents originally died shortly after his ComicBookDeath in ''ComicBook/CrisisOnInfiniteEarths'').
