RWBY: Amity Arena/Trivia

Characters Trivia

 * Out of all the humanoid characters with audio commentary, only Neo (who is mute) and Fox (who hasn't had a spoken line yet) do not speak their lines. Instead, the clips used are of Roman tasking her to use her Semblance onto the opponent, taken from the episode "Painting the Town...", and Coco complimenting Fox's battle skills, from "Breach". Both episodes also have the soundbites used for the Xiong Family ("Painting the Town...") and Dr. Oobleck ("Breach").
 * The January 2019 update added two new audio clips for Coco and Sun, with the former's taken from the episode, "Lessons Learned", and the latter's from the RWBY Chibi episode, "Big Vacation".
 * Both of Yang's quotes are taken from RWBY: Grimm Eclipse, and Nora's is from the episode, "Players and Pieces".
 * Cinder's quote derives from the episode "Dance Dance Infiltration".
 * Neon Katt and Flynt Coal's quotes derive from the episode "Never Miss a Beat".
 * The audio clips of Ruby shouting out the team attacks is derived from "Painting the Town...".
 * Roman's audio clip comes from "No Brakes".
 * Yatsuhashi's audio clip is derived from "Lessons Learned".
 * Neptune's audio clip is derived from "New Challengers...".
 * Adam's audio clip is derived from "Heroes and Monsters".
 * The Emblems in the character intros are mostly their personal ones or of the organization they are a part of. This also applies to characters who have Emblems that have not been revealed in series as of yet.
 * Examples of cards that have the Emblem of their organization are:
 * The Creatures of Grimm, Neo and Cinder having Salem's Emblem
 * The White Fang Thugs, Ilia and the Albain brothers having the White Fang Emblem
 * Examples of cards that have Emblems of their respective Kingdom:
 * Nolan and May having Vacuo's Emblem
 * The Xiong Family, Yatsuhashi, Fox, Oobleck as well as the Shopkeep having Vale's Emblem
 * Neon Katt and Atlesian Technology having Atlas' Emblem
 * Coincidentally, Neo, as well as Cinder, are some of the only characters in the game who have their own Emblems, but once their cards are obtained, the Emblem that can be seen in their backgrounds belongs to Salem.
 * This also applies to Raven as the symbol that appears during her character intro belongs to that of her twin brother, Qrow.
 * Starting with Ilia's release, new characters are revealed with the Amity Arena logo underneath them instead of their usual emblem.
 * Although Flynt's Semblance in the show allows him to make three more color-coded copies of himself, said copies in the game are not color-coded.
 * During the time where Neo and a handful of other new cards were added to the first major update of the game, the last part of her description talks about how she may or may not be capable of speaking, but after a recent update, this bit has been since then removed for unknown reasons.
 * Velvet's promotional package was named "The Velveteen Bundle" after the book that inspired her name, The Velveteen Rabbit.
 * Tyrian was revealed to be one of the cards that was made even before the BETA testing of the game but was not a part of it due to major spoilers.

Game System Trivia

 * During the second February 2019 update, they added the Beta testing for the game's Plaza Feature, which opens up for players every three hours for an entire hour where players can interact with each other outside of battle as their favorite characters.
 * On February 15th, 2019, they made it so that the Plaza would be available for everyone for the rest of the weekend while the developers sort out the rest of the coding and de-bugging.
 * Tapping the background art of each card twenty times allows the player to rewatch the intro sequence of the respective cards.
 * During the March 2019 update, the game introduces the concept of Legendary Cards as well as the team attack cards and the meta for the Battle of Beacon PvE.
 * This update was referred to as The Fall of Beacon update wherein players can purchase two bundles with two different limited edition titles per bundle at the shop. Wherein the first bundle gives you the title that is memory of Pyrrha as well as her last battle atop Beacon Academy's Tower wherein the second bundle gives you a title that is decorated with the debris of the damaged structures during The Fall.

Costume Trivia

 * With the four main girls and Jaune having multiple units, some of them use the post-Volume 4 redesign, namely Scythe Ruby, Ribbon Blake, Ice Flower, Bumblebee (which even has Yang with a mechanical arm) and Boundless Jaune.
 * Some of the units have alternate outfits, mostly the eight protagonists:
 * Scythe Ruby, Ice Weiss and Ribbon Blake have their pajamas (the first for early access players, the latter two, once the Cookie Shop was created during the game's first update), whereas Nora got an RTX shirt for those who attended the 2018 convention, while Sniper Ruby, Shadow Blake, Vomit Boy Jaune, and Pyrrha have their Beacon Academy uniforms which are accessible via Outfit Draw. Uniforms were made available for Scythe, Ice, Ribbon and Rocket in 2019.
 * As of the Christmas 2018 update, the pajamas of Team JNPR and the rest of Team RWBY are now available in the Cookie Shop. In Yang's case, it is Biker Yang, with a slightly altered color scheme (black top and orange shorts, an inversion of the show's pajamas) as well as a purple ribbon (which Yang normally ties around her leg) resting on her head.
 * Included in the Christmas Non-Descript Winter Holiday update is a Cookie Crate that can be brought with Chocolate Cookies that allows the player access the Christmas outfits of Nolan, May, Nevermore Chick and Ursa Major via Outfit Draw.
 * Another Christmas promotion had a holiday outfit for Penny that can be purchased alongside a handful of Dust Crystals.
 * On New Year's Eve, the game had a Prom Update which included Team RWBY's Beacon Dance outfits for Scythe, Ice, Ribbon and Biker.
 * In the first January 2019 update, they added the dance outfits of Penny, Neptune, Jaune and Sun.
 * In the first February 2019 update, they added Valentine's Day-themed outfits for Glynda and Qrow.
 * In the second February 2019 update, they added Roman and Zwei's Valentine's Day-themed outfits with can be purchased in the shop alongside a handful of Dust Crystals as well as Lovey-Dovey Crates.
 * The April 2019 event "Cinder's Ball" allowed the players to unlock Cinder's Beacon Ball outfit by winning 30 Fame matches.
 * On February 4th, 2019, RWBY Chibi concept artist, Hajime Nakamura, leaked Ice Weiss' new outfit which was included in the February 7th, 2019 event of the game.
 * The event is revealed to be called the "Ice Queen Weiss Mission", wherein players should engage in 50 Fame battles in the given week in order to get Weiss' new exclusive skin, which also has an alternate movement animation. When equipped with her new skin, the new animation has her skating through the field rather than the normal running animation.
 * On February 12, 2019, the developers have stated that the ice-skating animation for Ice Queen Weiss' skin wasn't originally made for her, teasing the later addition of Neon Katt.

Seasonal Event Trivia

 * During Halloween, all structures had floating Jack O' Lanterns above them. During the Christmas Non-Descript Winter Holiday, the turrets became snowmen and the tower became a Christmas Tree, snowflakes dangled from the game logo in the title screens, and it snowed in both the lobby as well as the arenas.
 * During New Year's, every post-game crate reveal was preceded by fireworks and a "Happy New Year" message along with the Amity Arena logo.
 * During Valentine's Day, the store was filled with candy hearts, ribbons and gift boxes, and a "Dum-Dum" banner (alluding to Neo's assessment of Roman in "Mysterious Red Button") was made available.
 * For April Fools Day, some of the models of the units in the game were switched around. These include:
 * Ursa Major becoming a Death Stalker
 * Baby Death Stalker Swarm becoming fifteen small Ursa
 * Lancers as well as the ones being spawn by the Queen Lancer turning into Zwei in his Valentine's outfit.
 * For Easter, along with the introduction of Velvet, the Beowolf Pack was given rabbit ears.

Character's backstories connected/related to RWBY

 * The game was the first to reveal some of Fox's backstory while confirming that he is indeed blind.
 * The game was also the first to reveal some of Adam's backstory.
 * The game was also the first to confirm that Raven was indeed previously married to Tai before she had left both him and Yang after giving birth to her.
 * The game is also the first to reveal that the team attack "Pomegrenade" was thought up by Jaune during the last second in order for them to fend against the Death Stalker he and Pyrrha came across in "Players and Pieces", wherein the team attack involves Pyrrha launching Nora into the air, thus making her land on a desired location with Maginhild. It is also revealed that after Pyrrha's passing, Jaune had to take her place instead.
 * Pyrrha's death animation in her Pomegrenade card is similar to that of her in-show death in the episode "End of the Beginning".

Crossover Characters from Other Media Trivia

 * Carmine Esclados was added days before her introduction in RWBY: After the Fall.

Miscellaneous

 * The Battle of Beacon introduction is given by Pyrrha, who references the Pumpkin Pete's shoot from "The One with a Laugh Track" ("that was almost as hard as eating Pumpkin Pete's again, and again, again..."), and has among its lines a flub by Jen Brown (“By clearing stages you can earn Lien, crates, and cards. Oh I said that backwards.”).
 * On May 17th, 2019, well-known RWBY content creator, @eunnieverse, was commissioned by the devs to make a comic teasing the upcoming release of the rest of the Faunus that were to be expected from the May 2019 update of the game, that being The Albain Brothers as well as Tyian Callows.
 * An easter egg involving Neptune when chosen in the Plaza can be activated once the player tries to make him swim. Instead of diving into the water he just keeps repeating "Yeah! I can guard this...sector."
 * As of the latest update, Winter Schnee is the most requested character that has yet to make an appearance in the game.
