* BittersweetEnding: Our heroes have saved reality!... or at least, a tiny fragment of it... Almost everything and everyone that ever existed is not just dead but erased from all memory. [[note]] [[AdvancingWallOfDoom (and they got to see their end coming inescapably toward them,]] so all those googol plexes worth of people died in sheer terror).[[/note]] And the coming months will show that even the survivors have been drastically altered by the experience, mostly becoming more [[DarkAge violent and depressed,]] and have no memory of ever having been otherwise, let alone of what caused it. So... yay?
* FountainOfMemes: Pick a cover. Any cover. They'll all become iconic (though probably the #1 is Superman holding a dead Supergirl.)
* HilariousInHindsight / 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, TheDarkAgeOfComicBooks!
* JerkassWoobie: The Psycho Pirate is a sicko and a coward yet it is easy to pity him when he goes mad from fear.
* {{Narm}}: "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.
** 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.
** 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?]]
* {{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.
