!!''ComicBook/KingdomCome''
* "Who Watches the Comicbook/{{Watchmen}}?" is written on the wall of a building.
* ''Under the Hood'' can be seen in a bookstore window.
* A gun-wielding ''WesternAnimation/FatAlbertAndTheCosbyKids'' are shown running away from a Bat-Bot, then getting surrounded by them.
* Green Lantern's Emerald City incorporates the ELO spaceship as part of its design.
* Music/TheBeatles can be seen playing in the club in #2--sort of. From the knees down. There was also an attempt for Sgt. Pepper HumongousMecha in the final battle scene, but that reference is nearly too subtle, even with annotation.
** In the same panel as the Beatles, Music/{{Tommy}} and the Acid Queen can be seen at the far left of the panel.
** Also the [[Music/TheMonkees Monkeemen]] and the [[Music/VillagePeople Village Warriors]].
** In the "WHOOM" panel above this one, [[Series/StarTrekTheOriginalSeries Mr. Spock]] appears to be standing in the background.
** [[Series/TheAvengers1960s Steed and Mrs. Peel]] can be seen at the bar.
** Literature/SherlockHolmes is standing behind ComicBook/SwampThing.
* At one point, the Kanji for "Heaven and Earth are Useless" are seen as graffiti. These are commonly read as "Anime/TenchiMuyo".
* The "LOBO WUZ HERE" graffiti on the ruined Art/StatueOfLiberty.
* When a huge number of super-powered people are charging in the gulag rebellion, several tiny Marvel characters can be made out, including ComicBook/CaptainAmerica, ComicBook/SpiderMan and [[ComicBook/TheMightyThor Thor]].
* Storm can be seen in the bar scenes.
** As can Rorschach.
*** The Wonder Twins are also bartenders.
* The Bjork poster.
* Two background characters, April Fool and Goblyn Lord, are based on Columbia and Riff Raff from ''Film/RockyHorrorPictureShow''.
* The Bat-Bots are modeled on the mecha from ''Franchise/{{Patlabor}}''. Batman's armor itself resembled Franchise/RoboCop.
* When Superman meets Scott Free and Big Barda, the jailers from ''Film/MontyPythonsLifeOfBrian'' are in the crowd.
* One of many cameos, a Background character in the gulag battle was visually based on XO-Manowar of Creator/ValiantComics. At around the same time as ComicBook/KingdomCome was being published, Mark Waid was also signed on the write the Acclaim Era Reboot of the character, ''XO-Manowar: Rebirth''.
* While Magog is mostly based on Cable, he has elements of other Rob Liefeld characters as well. Most notably, his helmet is based on that of Shatterstar's with the addition of horns.
* The center section of the Gulag is designed to look like the Hall of Doom from ''Challenge of the WesternAnimation/{{Superfriends}}'', and the UN building looks like the Hall of Justice.
* Captain Marvel Jr looks just like Music/ElvisPresley. A RecursiveAdaptation in that Elvis originally modeled his style after Captain Marvel Jr.
* In his brief appearance, ComicBook/TheJoker looks like an aged Creator/JackNicholson from Tim Burton's 1989 ''Film/{{Batman|1989}}'' movie (by coincidence, he also comically looks a bit like Silvio Berlusconi).
* The minor character Tokyo Rose resmebles a Japanese-themed [[Franchise/StreetFighter Chun Li]].
* Phil Sheldon from ''ComicBook/{{Marvels}}'' sits next to Norman and The Spectre in the epilogue.
** He's also among the crowd of newspeople during the Justice League's press conference.
