- Alternate Character Interpretation: Batman breaking his one rule to stop Darkseid from using a Kryptonian as an enforcer was a bluff. Right? There is a lot that could speak for or against the bluff.
- Evil Is Sexy: The female Furies, but Kara especially during her brief stint as their leader.
- Inferred Holocaust: Wonder Woman and Harbinger ambush Kara and Superman in a park to demonstrate the risks of leaving her in the city without proper training, highlighting her inability to control her powers and the massive collateral damage that results. She points out that if this attack had happened in daylight, with people in the park, there could have been countless innocent casualties when Kara lost control of her heat vision. Nobody seems to notice that her beams do not stop after twenty feet: the eye beams that missed the local statues and furniture will keep going until they hit something (or dissipate after a couple miles). Given that this is a major metropolitan area, the odds are very good that Kara just directly vaporized a person, or demolished a building. More immediate to the discussion is that, since Kara and Superman were walking in the park as simple tourists, it is obviously not empty just because it is night. (And you know Clark wouldn't have had her out very late.) Though fewer in number than during the day, there would still plenty of people in the immediate area to be killed during this "demonstration."
- Just Here for Godzilla: Plenty of characters just watch the movie for Supergirl. This version of her is second only to her DCAU portrayal in popularity, at least as far as animated versions of the character go. Said fans are generally satisfied in that area even if they don't like Batman's behavior, Darkseid's new voice actor or other elements of the film.
- Magnificent Bastard: Batman himself, while more ruthless than usual, remains just as cunning as ever. After managing to subdue Supergirl herself with Kryptonite, Batman goes behind Clark's back to bring Wonder Woman into the fold, encouraging Kara to train on Paradise Island instead. When Darkseid attacks, Batman realizes only a moment too late that the attack was a diversion, realizing that Darkseid wants Kara for his own army. When the trio make their way to Apokolips to bring her back, Batman confronts Darkseid himself head-on, revealing that he has armed the hellspores in his armory and that he will detonate all of them, destroying Apokolips in the process, if he doesn't promise to never attack Supergirl again. Shocked at his pragmatism, Darkseid agrees, and the trio return to Earth successful.
- Memetic Mutation:
- Narm:Kara: I sensed your [Batman's] presence earlier because I thought I heard your heartbeat. I was wrong. You have no heart.
- Retroactive Recognition: Darkseids new voice sounds a lot like Capt. Raymond Holt.......
- They Changed It, Now It Sucks!/What the Hell, Casting Agency?: There was a large uproar when Michael Ironside was replaced by Andre Braugher as Darkseid, a role Michael had played in both Superman: The Animated Series and Justice League, especially in light of the fact that Tim Daly, Kevin Conroy, Susan Eisenberg, and Edward Asner were reprising the roles of Superman, Batman, Wonder Woman, and Granny Goodness. Likewise, though Summer Glau was almost universally well received when she was announced as Supergirl, there were still several requests from fans for Nicholle Tom to return to the role that she had also played during the DCAU.
- Viewer Gender Confusion: Granny Goodness is a woman, but people unfamiliar with the Justice League franchise will have a hard time guessing unless it's pointed out to them.
- The Woobie: Kara. First she watches her parents die, then she's trapped in an unfamiliar environment, forcibly gets kidnapped, is treated like a child, kidnapped again, brainwashed into being an evil assassin and leader of an army of super hot warrior assassins, is forced to attack her cousin while being brainwashed... seriously, the girl goes through so much.
