* AuthorsSavingThrow - ''Fantastic Four 2099'' was supposed to star the actual Fantastic Four, briefly brought to the year 2099 by accident and trying to find their way home/save the world. It ended with [[spoiler: The Thing getting killed in a shuttle accident, and the rest of the team promptly forgetting he ever existed and going home without him.]] ''Manifest Destiny'' gave a different explanation: [[spoiler: the team was actually {{Artificial Human}}s created by the Watcher, because he thought his old allies would be able to help save the dying Earth. All four are brought back into existence in the end.]]
* DorkAge: Cavalieri's firing and the ensuing WriterRevolt unsurprisingly led to this.
* HilariousInHindsight - With a hint of [[{{Irony}} irony]]. During his early Spider-Man works, ''Spider-Man 2099'' writer PeterDavid "revealed" that Ned Leeds was the original Hobgoblin--which several fans thought was questionable given how Leeds died and the original Hobgoblin mystery writer, Roger Stern, came back and revealed that it wasn't the case. [[http://groups.google.com/group/alt.fan.peter-david/msg/4e9186e3c4855006?hl=en& David had intended Father Jennifer to be the (Green) Goblin 2099]], but it was revealed that [[spoiler: Gabriel O'Hara was Goblin 2099 (though this was later retconned to be an imposter)]]. Someone had to appreciate the irony, even if (as the link shows) David himself doesn't.
** This verse's Comicbook/GhostRider is named [[Manga/FistOfTheNorthStar Kenshiro]]...who is technically [[YouAreAlreadyDead already dead.]]
* MagnificentBastard – No matter the century, Doom is the all-powerful master of this trope.
