* FountainOfMemes: Pick a cover. Any cover. They'll all become iconic (though probably the #1 is Superman holding a dead Supergirl.) Which admittedly the Superman/Supergirl cover wasn't the first instance of PietaPlagiarism in comic covers.
* HarsherInHindsight: Psycho Pirate's MadnessMantra ends with "These days... y-you just never know who's going to die... and who's going to live." Hello, UsefulNotes/TheDarkAgeOfComicBooks!
** DC's attempt to clean up their messy continuity with a rebooted universe using strict rules on time travel, a winnowing down of characters who duplicated each other, and no alternate Earths. Except they didn't do a clean sweep of the slate (Power Girl and Donna Troy in particular), leaving too many loose threads that required further reboots to try and fix the previous errors.
*** Eventually DC decided to reboot everything ''again'' and introduced a new multiverse, though it was still very limited (only 52 Earths this time). One cannot help but imagine DC's editors throwing their hands up into the air in frustration after being asked for years about the loose ends and contradictions resulting from ''Crisis''.
** Earth D's Robin, who is Batman's son in this earth, which has become a prediction for Damian Wayne.
** A superheroine named Harbinger is mind-controlled by an exceptionally powerful EldritchAbomination to do his bidding. You could almost say he was [[VideoGame/MassEffect2 assuming direct control]] of her.
* JerkassWoobie: The Psycho Pirate is a sicko and a coward yet it is easy to pity him when he goes mad from fear.
** "It's not fair. She shouldn't have died for me. Where is he? The Anti-Monitor. I... '''I want to kill him for this!'''" It's the horrible punctuation that really sells it.
** Wolfman always has embraced the natural cheese that comes with the comic book medium, but here, simply the amount of characters present, and his need to have each one's name spoken aloud by another character, along with multiple characters thinking repeatedly about what their powers enable them to do, ramps up the narm factor exponentially.
** That one panel where the Anti-Monitor appears to be air-guitaring.
** Uncle Sam's speech to the gathered heroes is really hard to take seriously. Of course, that might have been the point, as right afterwards the line "What a cornball!" is said about him.
** When the Challengers of the Unknown realize the darkness in the sky is composed of millions of shadow demons, they're naturally shocked. Unfortunately, June expresses that shock by saying each of her teammate's names all in a row. Seems very unnatural.
** Did poor Wally really have to say twelve little no's followed by one big one when he sees [[spoiler:Barry Allen's empty costume?]]
** When Peacemaker is hit by an explosion in the final battle, he screams "The pain... ''The pain!!''" It's a line more fitting in a bad drama play.
** On the same page, Prince Ra-Man is hit, and his comrade Shade reacts thus: "They've got Prince Ra-Man. This will be ''harder'' than I thought, but we ''will'' prevail." Doesn't seem like a normal reaction to a comrade dying, except if you don't like him.
* NightmareFuel: [[spoiler:The gruesome death of the Silver Age Flash/Barry Allen, crumbling away like dust as he makes his HeroicSacrifice. Punctuated with the other heroes arrive and witness Psycho-Pirate frantically tugging on his empty costume deliriously calling for his help.]]
** People being eradicated by the encroaching white wall of anti-matter
** The concept of an annual Crisis-level crossover event was pretty daring in the early 1980s. Today, the major universe continuities - Marvel and DC - have done so many they've become expected.
** The killing off of A-list heroes - Flash and Supergirl in particular - along with C-list and D-list cannon fodder characters was rare before DC made it a major selling draw.
* TearJerker: Even if you thought pre-Crisis DC was a mess, it's still pretty upsetting to see several different alternate continuities come to an end in a single story.
* TheWoobie: Pariah.
