** ''ComicBook/GreenArrow'' had the title character killed and [[LegacyCharacter replaced by his son]]. ([[BackFromTheDead He got better]], but not for a decade).

* ComicBook/UsagiYojimbo had two within the span of four years. The 100th issue published by Dark Horse featured an out of continuity banquet in Usagi's honor and featured guest artists and characters from Dark Horse. In #141, the series celebrated its 200th overall issue with a story about Usagi and an AuthorAvatar of Creator/StanSakai stopping bandits from terrorizing a town.

*** Issue #200 features the wedding of Bouncing Boy and Damsel Duo, one of the most iconic couples of the ComicBook/LegioinOfSuperHeroes.

* In the Franchise/DCUniverse, several ComicBook/PostCrisis titles hit #100 at about the same time in UsefulNotes/TheNineties. All of them were given special prismatic covers. In addition:

* ''ComicBook/LegionOfSuperHeroes'' had a #300 in 1983 which was the 25th anniversary, which put to rest the [=AdultLegion=] story and brought back artists (and even logos) from various eras of the Legion. Natural for a comic published every month for 25 years -- except it wasn't. The Legion had moved between comics and ended up getting the numbering of the ''Superboy'' comic, which wasn't monthly throughout its run; the fact that issue #300 was the 25th anniversary was ''pure coincidence''. Also, the 10th anniversary (Superboy #147, 1968) finally revealed the origin of the Legion. The 30th anniversary (volume 3, #45, 1988) brought back the older artists again. The Legion has also done standard anniversary issues according to the cover numbering, meaning that V3 #50 was an anniversary issue with a letter column commenting on another anniversary issue.

*** In a non-centennial instance, issue #544 (celebrating the 45th anniversary of Action Comics, and still pre-Crisis) introduced Lex Luthor's [[PoweredArmor warsuit]] and Brainiac's new robotic body.

*** Video games: ''VideoGame/BatmanArkhamKnight'' was supposed to fill this role, but it got delayed to 2015. Also, a {{UsefulNotes/Steam}} sale on the rest of the ''VideoGame/BatmanArkhamSeries'' on the exact anniversary weekend of March 28-30.
