The sequel to Superman/Batman: Public Enemies and the first sequel in the DC Universe Animated Original Movies line.The film begins with a huge meteor crashing into Gotham Bay, alerting the attention of Batman to the scene. The meteor turns out to have contained a spaceship belonging to a girl possessing the strength and powers of Superman. In her confusion and fear, she causes enough damage to warrant Batman using kryptonite to subdue her. Awakening in the Batcave, she destroys Batman's scanning equipment, but her attempt to flee is halted by Superman. Able to understand her language and provide her reassurance, Kal-El learns she is his cousin, Kara Zor-El.Superman offers to take the young Kara under his wing, despite Batman's suspicions, and teach her how to live among the humans. However, Darkseid knows of her arrival and makes plans to use Kara for his own means.The direct-to-video adaptation is based on "The Supergirl from Krypton" story arc in Superman/Batman. Kevin Conroy and Tim Daly reprise their roles from the first feature and Susan Eisenberg returns as Wonder Woman, whilst Summer Glau voices Supergirl.
Adapted Out: Bernadeth, another members of the Female Furies who was in the comics isn't in the movie version. Then again, in the comics, she spent the entirety of the Furies' fight with Wonder Woman and Big Barda on the sidelines with Granny. The comic version of the scene at the end when Superman introduced Kara as Supergirl also had the Justice League of America, the Justice Society of America, the Teen Titans, and the Outsiders in attendance.
Artistic License - Physics - Early on, we see a blimp damaged, and it promptly falls towards the ground like a plane. They're called "lighter-than-air craft" for a reason, folks.
Art Shift: Public Enemies tried to emulate the art syle of Ed McGuinness, who drew the comic version of PE. This movie has an art style trying to emulate the late Michael Turner, who drew "The Supergirl from Krypton".
Badass Normal: Batman takes out Supergirl, meets an army of Doomsday clones with a "bring it on" attitude and defeats Darkseid by holding his entire planet hostage.
Conservation of Ninjutsu: The pre-battle overhead view shows that the army of Doomsday clones outnumber the Amazon's by at least two-to-one, but the Amazon's still hold them back and even Batman, normal human though he is, is able to best them in hand-to-hand combat. The fact that they are clones might cover this, except they apparently retain enough strength to knock Superman to the ground and cause him visible pain.
Continuity Nod: The opening scene featured a radio announcer giving a synopsis of the events of the first movie, including the kryptonite asteroid and President Luthor's impeachment. Much of the information has little bearing on the plot of this film, but it does set the stage for Supergirl's arrival, explaining where the Kryptonite meteor shower came from.
The Dragon: Kara was this to Darkseid during her stint as leader of the Furies. It was a short stint but she did a pretty good job.
Evil-Detecting Dog: Subverted. Krypto does not seem to like Kara at all, a fact that Batman points out given that he is a good judge of character. However, Superman believes his dog is just being a little overprotective and Kara herself is quite evil-free.
Big Barda is introduced wearing only a towel, and you can see her shadow while she gets dressed.
Fauxshadow: We're explicitly shown that the Furies are being sent to abduct Kara, and later we see a shadowy group of female warriors trying to abduct her, including one who uses what appears to be a whip (a la Lashina). But it turns out to be Amazons (including Wonder Woman with her lasso).
I Broke a Nail: Kara's final complaint after the Apokolips adventure is that she broke a nail.
Idiot Ball: It seems the Amazons and Wonder Woman of all people pick this up when they go to seek out Kara to train her to control her abilities. Apparently Wonder Woman assumed Superman to be such an unreasonable person that simply requesting her be trained was out of the question. Instead they opted to kidnap her, whilst her cousin was with her. Made worse that when things eventually calm down, Kal-El actually sees the reason in the move and agrees even after being attacked
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."
Limit Break: When Superman realizes that the Doomsdays are pushing back the Amazons, likely to overwhelm them, he stops holding back and destroys the lot of them with his heat vision.
Magic Skirt: Kara first appears naked, then gets her hands on a trenchcoat, after which her flight powers are awakened. This involves her flipping upside down a few times. You do the math.
Market-Based Title: It's generally believed by fans of the comics that WB's disappointment at Wonder Woman not meeting WB's expectations is the reason the movie is called Superman/Batman: Apocalypse and not Superman/Batman: The Supergirl from Krypton.
Misplaced-Names Poster: A variation. The opening credits show the logos of the superheroes/villains that appear in the movie, but the actors' names shown alongside them don't match, with the exception of Batman/Kevin Conroy. Andre Braugher (Darkseid) appears with the Superman logo; Tim Daly (Superman) appears with the Wonder Woman logo; Summer Glau (Supergirl) appears with a logo resembling Big Barda's helmet; and Edward Asner (Granny Goodness), Susan Eisenberg (Wonder Woman), and Julianne Grossman (Big Barda) appear with a helmet logo for Darkseid.
More Than Mind Control: After she is freed, Kara confesses she fears this about how Darkseid took control of her; Superman firmly dismisses that, noting that Darkseid has many resources and specialists to bend anyone's will to his control.
Only Six Faces: The main characters are all visually distinct from one another, but they blur together with supporting characters to an extent that almost seems deliberate. The writers seem to realize this, since when Lyla dies her name is actually spoken aloud so that it is clear whose body is being held. Apparently this is actually the case in the movie, as Harbinger is not able to recognize herself in a prohetic vision, mistaking her own body for Supergirl's.
Papa Wolf: Superman. Any indication of someone even attempting to harm Kara is pretty much Kal-El's Berserk Button.
Power Incontinence: When Supergirl first arrives on earth she has a lot of trouble controlling her powers. This results in several scenes where her laser vision activates that she cannot turn off, and even an occurance of her floating off the ground and being unable to get down again.
Red Shirt Army: The Amazon soldiers who engage the Doomsday clones. By the end of the battle, there's barely enough of them to form a single-file line, out of what appeared to be an entire battalion.
Show, Don't Tell: The movie features many time jumps (ranging from a few hours to a few months) and attempts to reveal what happened in this missed time with clumsy exposition. Kara shares only a single scene with Lyla, during which they both talk about how great it is that they are best friends and have been for several months, and Superman and Supergirl battle over Apokolips while Superman exposits that its clear Darkseid has complete control over her. However, never is there a scene showing Kara and Lyla forming a friendship, or a scene showing any kind of brainwashing, torture or mind control being used on Supergirl. Much of it simply has to be taken on faith that it happened at all, and it lessens a lot of the impact of the events on-screen.
Space Is Cold: Darkseid's body freezes solid in the void of space when he is sent there after Kara reconfigured his Mother Box.
Stunt Casting: Bruce Timm admits it's the reason behind most of the casting choices for the DC Animates series, including choosing Braugher over Ironside.
Swiss Cheese Security: Apokolips might have plenty of roving bands of bloodthirsty monsters, but actually having somebody stationed near the room filled with planet-busting bombs, or having a guard outside the door to Darkseid's chambers, seems to be expecting too much.
Take Our Word for It: None of the brainwashing of Supergirl is shown on screen, nor is it even described in detail. She appears, acts Brainwashed and Crazy and Superman describes her as being controlled by Darkseid, but we have only his word for this. There is no on-screen evidence at all to even imply that Supergirl is acting under any sort of coercion.
Thou Shall Not Kill: Though Superman would never intentionally kill anyone, he does warn Darkseid to never come back.
What Measure Is a Mook?: It is explicitly stated that Granny Goodness and Darseid exploit brainwashing and conditioning in their soldiers, forcing people to fight for them, so why does nobody seem at all concerned when they are killing off the Female Furies?
What Measure Is A Nonhuman: It is only after Diana points out that the Doomsdays do not bleed that Superman begins to stop holding back, and after he kills (destroys?) the group she comforts him with the fact that they were not really alive at all. Of course this brings up some questions since Superman had frozen and smashed two of the clones earlier without hesitation or sign of guilt.
Witch with a Capital B: Kara uses it on Granny Goodness. One wonders why, when Guillotina calls Barda a bitch later on.
Your Princess Is in Another Castle: The movie seemingly ends with Clark getting ready to introduce Kara to his adoptive parents. Cue Darkseid coming out of nowhere and punching Superman through the front door.
