* The show's creators mention that they created a replica of this show's version of the utility belt out of cardboard, to test and see how it would work in motion.
* DistancedFromCurrentEvents: The guns were re-edited [[FamilyFriendlyFirearms in more of a sci-fi style]] following the 2012 mass shooting tragedy in Aurora, Colorado.
* InvisibleAdvertising: This show and ''Teen Titans Go!'' replaced the previous DC Nation, but you wouldn't have known that from the total lack of advertising for this show, which had been mostly been shown to the public through press releases alone until a few weeks prior to the premiere. ''Teen Titans Go!'', on the other hand, has been given [[AdoredByTheNetwork lots of advertising]] weeks before it premiered and technically airs in a primetime slot with reruns on DC Nation.
* NetworkToTheRescue: The show moved to Creator/{{Toonami}} on May 10th, where it aired ''all'' 26 of its episodes before CN executives wrote off the series as a financial failure and forbade reruns.
* NoExportForYou: Despite having its Latin American dub for all 26 episodes, has not aired in Latin America. At least the DVD releases in US (Region 1), Mexico (Regions 1 and 4) and Argentina (Region 4) include this dub.
* PlayingAgainstType:
** As with [[Film/StarTrekVITheUndiscoveredCountry The Federation President]], [[Series/{{Resurrection}} Henry Langston]] and [[WesternAnimation/GreenLanternTheAnimatedSeries Shyir Rev]], we have Creator/KurtwoodSmith playing a much nicer character than he usually plays. Like the latter two, we also have Smith playing a better father than [[Series/That70sShow Red Forman]] and [[Film/DeadPoetsSociety Mr. Perry]]. He's also playing one of the most famous cops in fiction, whereas one of Smith's more famous roles was [[Film/RoboCop1987 Clarence]] [[CopKiller Boddicker]].
** It's incredibly unsettling listening to Anarky knowing [[Creator/WallaceLangham he was once]] [[WesternAnimation/MissionHill Andy French]].
* RoleReprise:
** Creator/TaraStrong voices Barbara Gordon, reprising her voicing of the character in the Franchise/DCAnimatedUniverse.
** In the French dub, several voice actors from previous adaptations reprised their roles here:
*** From the Franchise/DCAnimatedUniverse: Jean-Claude Sachot as Lieutenant/Commissioner Gordon and Creator/PhilippePeythieu as Man-Bat/Kirk Langstrom.
*** From ''WesternAnimation/TheBatman'': In addition to Gordon, Creator/AdrienAntoine as Batman/Bruce Wayne, Chantal Baroin as Oracle/Barbara Gordon, and Thierry Murzeau as Killer Croc.
*** From ''WesternAnimation/BatmanTheBraveAndTheBold'': In addition to Batman, Oracle, and Killer Croc, Jean-Claude Donda as Ra’s Al Ghul.
*** From ''VideoGame/BatmanArkhamCity'': In addition to Batman and Gordon, Jérôme Pauwels as Harvey Dent.
* ScrewedByTheMerchandise: Mitch Watson [[https://www.youtube.com/watch?v=ttAZSt6CX8o revealed]] that, in addition to CN's lack of support, what cost this series another season was the lack of a toyline. Mattel initially contacted Watson and Glen Murakami about working on toys before changing their mind, mentioning that they already had a current toy line they were focusing on. With no financial support, the show was doomed to only last one season.
* ScrewedByTheNetwork: The InvisibleAdvertising and erratic scheduling after the first few weeks were bad enough. Then it was pulled from the schedule altogether and left in limbo ''for months'' with no official word from Cartoon Network about the show's fate. Cast members assured that it would return in early 2014, and even that changed as their promised dates came and went. Keep in mind the episodes had already all been produced; they were airing in New Zealand this whole time and some of the episodes were released on DVD before they had ever aired in the states; Cartoon Network just ''outright refused'' to air the show or even comment on its ongoing status one way or the other. Eventually Toonami [[NetworkToTheRescue came to the rescue]]...
** But even Toonami rescuing the show was in vain. Cartoon Network wrote off the show financially, preventing it from airing on Toonami ever again. At least Toonami kept to their word and gave the show a 7-episode marathon so that it could at least reach its conclusion.
** Given the climate of entertainment today, where comic book adaptations are some of the hottest properties around, the fact that Cartoon Network either could not or would not make a killing off a Batman show is mind-boggling. Batman is the single best-selling comic book there is, and has already [[Series/Batman1966 had]] [[WesternAnimation/BatmanTheAnimatedSeries five]] [[WesternAnimation/BatmanBeyond successful]] [[WesternAnimation/TheBatman television]] [[WesternAnimation/BatmanTheBraveAndTheBold adaptations]] going back to the 1960s-- to say nothing of his films and video games. Batman prints money, he's the very definition of a cash cow, to the point where [=DC=]'s basic marketing strategy sometimes feels like "Make everything as similar to Batman as possible." There are no words, basically, for how hard you have to try to ''not'' have a successful Batman adaptation. Even the Toonami promos for the above-mentioned 7-episode finale marathon seemed to highlight the ridiculousness of the situation, ending with a very telling quote from the show:
--->It wasn't supposed to end like this.
** At the end of the day, the only possible explanation as to why Cartoon Network screwed ''Beware'' is because it was very expensive to produce, as well as its historic preference for comedies over action shows due to pressure from MoralGuardians, and even though it was getting over a million viewers per episode during the ''DC Nation'' run (the ninth episode, "Control", garnered 1.52 million viewers), they pulled the plug and went all-in on ''WesternAnimation/TeenTitansGo'', and the rest is [[AdoredByTheNetwork/TeenTitansGo history]].
* ShortRunInPeru: During the late 2013-early 2014 hiatus, new episodes continued to air in New Zealand, of all places.
* WhatCouldHaveBeen:
** ComicBook/TheCreeper was at one point considered to be in the show. Villains such as [[http://www.therobotsvoice.com/2013/07/tr_interview_beware_the_batman_producers_mitch_wat.php Mad Hatter]], [[http://www.toonzone.net/sdcc2013-beware-the-batman-screening-and/ Nocturna, and Hush]] were also considered, with the last one being replaced by a similar villain (likely Deathstroke, due to [[CompositeCharacter borrowing characteristics]] from Hush).
** There were considerations to do a show [[http://voicesfromkrypton.net/exclusive-supermanbatman-series-that-could-have-been/ centered around Superman and Batman]] that went through at least two different forms (one was dark and apparently kind of like ''Film/EscapeFromNewYork'', while the other focused on Batman and Superman living together, as well as [[LighterAndSofter being much lighter]] than what the show would become). The latter was also [[https://player.fm/series/the-nightfly-with-dave-juskow/live-from-los-angeles-with-mitch-watson going to feature Wonder Woman]] and a relationship between the three. (around the 23:40 mark).
*** Adding onto this, [[https://mobile.twitter.com/DCAUResource/status/1256797255182368768 James Tucker]] would've been in charge of development with Mitch Watson.
** In an interview, the show's creators commented that it would be focused more on Bruce Wayne, and would show "the three faces of Bruce": the millionaire playboy; the paranoid shut-in; and Batman, the moderator between the two sides.
** Designer Shane Glines [[https://64.media.tumblr.com/1705687d2eb7e3ff3fa6143f6c866a33/6097556c7e8dad3a-d2/s2048x3072/b4371268e45aa85e711a5f6174a42e3be0b2a305.jpg actually had concept art]] ready for Two-Face.
** There was actually [[https://www.comicbookmovie.com/batman/beware-the-batman-is-this-concept-art-for-the-joker-a102005 concept art for the Joker in the series]] despite the many claims that he wouldn't have been used. It was most likely a change made later on to differentiate from other adaptations.
** The episode [[https://mobile.twitter.com/jim_krieg/status/1288526951213228033 Tests]] turned out differently according to Jim Krieg. He said how he and the producers originally envisioned Anarky with a different origin story. He would've been a giddy, young masked vigilante that would've seemingly been on Batman's side, similar to Robin, before his true colors were revealed.
** Glen Murakami revealed [[https://www.instagram.com/p/CS_FhZurasx/ a rough sketch]] of what the Outsiders line-up would've looked like in season two: In addition to Batman, Metamorpho, and Man-Bat, Cyborg and a Robin-like Red Arrow would've joined the team. Also, Murakami revealed that Tatsu would've become the show's version of Nightwing, while Barbara would've become Robin, resembling Carrie Kelley.
*** Head writer Mark Banker [[https://twitter.com/themarkbanker/status/1459205169837588487 mentioned]] that other plans included new villains, the return of Killer Croc and a "big reveal".
** Mitch Watson mentioned [[https://www.youtube.com/watch?v=f6fnxa5615c in an interview]] (28:35) that he wanted to portray Oracle in a wheelchair, as in the comics, but Cartoon Network did not want to have characters in wheelchairs because "it was too depressing".
