* BrokenBase: ComicBook/CrisisOnInfiniteEarths- it was either the best thing to happen to the DCU or the worst.
** And more recently, the New52 Reboot for largely the same reasons.
* GenerationalSaga, just modified. The JSA characters, i.e. the first Green Lantern and Flash being the first generation, followed by the next generation of superheroes such as Batman, Wonder Woman, and Superman, followed by the generation of their sidekicks, such as the Robins, Wonder Girl, Superboy, et cetera.
