* IKnewIt: [[spoiler: Some connected the dots between Dane Lisslow and Deathstroke early, considering Dane and Bruce had so much in common, and Deathstroke had both of his eyes.]]
* 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 will be moving to Creator/{{Toonami}} on May 10th, where it will air ''all'' 26 of its episodes.
* ScrewedByTheNetwork: The InvisibleAdvertising and erratic scheduling after the first few weeks were bad enough. Then it was pulled from the schedule altogether and is currently in limbo and supposedly set to return sometime in the first half of 2014. It's not as if the episodes aren't there, either. The DVD release rounded off the first half of the season, and New Zealand is going ahead with the second half. For whatever reason, Cartoon Network is just refusing to air it. At least Toonami [[NetworkToTheRescue came to the rescue]].
* ShortRunInPeru: During the late 2013-early 2014 hiatus, new episodes continued to air in New Zealand, of all places.
* TooSoon: The series was re-edited to have less realistic fire-arms following the tragedy in Aurora, Colorado.
* WhatCouldHaveBeen: ComicBook/TheCreeper was at one point considered to be in the show.
** 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).
