In "Hereafter", after Superman is apparently killed, Flash stops Diana from killing Toyman, stating that they (especially Superman) "don't do that to [their] enemies". Flash forward to JLU and "Divided We Fall", when Luthor has apparently killed Flash: who springs forward to stop Superman from killing Luthor? Diana. And then she's stopped by Batman, who trusts Clark and knows he won't commit murder, because even in these circumstances, "[they] don't do that to [their] enemies".
The focus on Batman and Wonder Woman's reaction is also a contrast to their Justice Lord counterparts. They were the first to witness the aftermath of Superman's murder of Luthor. And they accepted it. Here, they of course do not, which once again proves how Superman and the Justice League will never become like the Justice Lords.
Brought up in the Radar page: "Epilogue", which was meant to be the end of the DCAU, consists of Amanda Waller confessing to Terry the secrets about his origin. In other words, the Fat Lady is singing.
In "Epilogue", there is another reason why The Phantasm was unable to kill Terry's parents. While it is true that taking a life wouldn't honor the memory and spirit of Batman, there is also the point that Andrea Beaumont couldn't bring herself to harm Bruce Wayne's son, not even psychologically. She loved him that much.
When Aquaman saves Grundy in "The Terror Beyond," he gets Grundy to come with him by promising him gold. Grundy doesn't seem to have any want to buy anything and just enjoys having it (rubbing it lovingly against his face), though once he becomes aware of how he has no soul, he calls the gold worthless and demands that. Grundy's love of gold is either a holdover from his past life as a greedy, materialistic gangster, or an unconscious pining for the human side of himself; Cyrus Gold.
In the climax of "Legends," it's clearly established that the Justice Guild is merely a figment of the mutant boy's imagination. So why did they turn on him, if they were part of his own fantasy? Simple. Even in the boy's own version of reality, he simply could not imagine them doing anything other than the right thing. Even if it meant taking him down, and ending their own existence.
Justice Lord Superman's tendency to use heat vision to lobotomize people makes sense for 2 reasons:
1. He can still claim he didn't technically kill his opponent since most of them survive it and become docile as a result.
2. He killed President Luthor with heat vision. As much as he claims he's better off without him Lord Superman is trying to fill the void Luthor left by reliving killing him over and over again.
"Injustice For All" of corse the traitor in the Injustice Gang wasn't Cheetah. First, Wonder Woman didn't correct Superman when he asked who "he" was. Second, if anyone would recognize Cheetah's voice...
The Z-8 drone that appears in the Unlimited episode "Fearful Symmetry" makes a recursive moment for the Batman Beyond episode "Zeta". By building Zeta out of an old training drone chassis, it makes it really hard to track who actually made it, on the off chance it was compromised or destroyed.
Batman trapping David and Enid in a time loop may seem uncharacteristically chilling, putting it in the Nightmare Fuel page. But think about it, Batman knows how dangerous even messing with time is, and he's not a monster. He no doubt set up that time loop counting on the future JL to detect it, find and free David Clinton, and arrest him. So basically, Batman didn't trap Clinton in a Fate Worse Than Death, he just set off a huge neon light saying "come and get me" over Clinton's house.
During Flash's battle with Brainthor in "Divided We Fall", we see the former literally circling the Earth in a matter of seconds for a running start. This requires traveling at a fraction of the speed of light. At that speed, the kinetic energy would flatten any object in his path. Raindrops. Insects. Birds. Buildings. People. It's the horizontal version of Not the Fall That Kills You. And Flash has milliseconds to react and veer off should he spot something—or someone—in his way.
This goes back to Fridge Brilliance in terms of why the first strike at Brainthor took ten seconds, whereas the Flash could later strike him four times in a couple of seconds: he needed time to determine the safest path around the world.
Lex Luthor defeated Darkseid by showing him the Anti-Life Equation. This means that if Darkseid ever comes back or his servants bring him back from the dead, the Timmverse is screwed.
Word of God says that both Luthor and Darkseif are alive... but merged with the Source Wall, so I doubt they will be able to come back...
When Lex Luthor hijacks the Watchtower's Binary Fusion Cannon, and targets CADMUS. The first reaction shots are of a simple, bright white light. To anyone nearby, it would have looked liked the predicted effect of a nuclear attack. Judging from the sheer devastation from the clean up, casualties are certain, and their last thoughts were about the horror of nuclear weapons. America's Greatest Fear come true.
More like a Fridge Tear Jerker, but reflect on this: It's probably not long after the finale that Tim Drake is kidnapped by the Joker and Harley Quin. That incident is what leads to Bruce slowly cutting himself off from all contact until we see him old and alone in "Rebirth". Look back at how many allies Bruce had to have gained through the League, especially how close he was to Clark and Diana; realize that he'll eventually be shutting THEM out as well.Sorta sours that ending, doesn't it?
In "Maid of Honour", since we never find out the fate of the King of Kaznia and the rail-gun destroys the castle where he was last shown, we're left with the realisation that Batman of all people may have just accidentally killed Princess Audrey's father with a big honking space-gun!
Wasn't he supposed to be at the hospital?
Actually, there's a blink-and-you'll-miss-it shot of a Kaznian soldier carrying someone in purple, similar to what the king was wearing in bed, away from the palace over his shoulder.
In "Hereafter" the first thing Superman does when he returns to the past is save Batman from a sniper shot. Batman died in the original timeline. Savage only said that the League tried to stop him, but the only specific member he named was Green Lantern (who was apparently the hardest to kill); if Bats doesn't merit a mention from Savage, he likely was successfully sniped in the original timeline. Tough as he is, he's still only human and the only non-empowered member of the League.
