List of Minor Universes

Main Article: Universes

This article documents all Warner Bros. Discovery-owned franchises with smaller forms of representation in MultiVersus.

Animaniacs
Animaniacs is a variety show, with short skits featuring a large cast of characters. While the show had no set format, the majority of episodes were composed of three short mini-episodes, each starring a different set of characters, and bridging segments. Hallmarks of the series included its music, satirical social commentary, pop culture references, character catchphrases, and innuendo directed at an adult audience. A revival of the series was announced in January 2018 and ran for a total of 3 seasons from February 20th, 2020, all the way until February 17th, 2023.

The iconic Warner Bros. Water Tower's depiction from this show appears on The Court Map as a background element, although its design has been altered in-game due to unknown reasons.

Captain Planet
Captain Planet is an American animated environmentalist superhero television series franchise created by Barbara Pyle and Ted Turner. The franchise consists of two different cartoon series: Captain Planet and the Planeteers and The New Adventure of Captain Planet. Both programs are a form of edutainment that advocate environmentalism and are known for having a number of famous actors providing voices for the villains. The shows spawned a franchise consisting of eco-friendly toys, comic books, video games, and a public charity to further promote the work of the show.

The elemental rings of fire and earth, that appear in Morty's Up Aerial Attack (Power of Fire!) and Grounded Side Special (Power of Earth!) respectively, are based off of the elemental rings from this franchise and originate from Rick and Morty 's "A Rickconvenient Mort" episode, which heavily parodied the original Captain Planet show.

The Matrix
The Matrix is an American media franchise consisting of four feature films, beginning with The Matrix (1999) and continuing with three sequels, The Matrix Reloaded, The Matrix Revolutions (both 2003), and The Matrix Resurrections (2021). The series features a cyberpunk story of the technological fall of humanity, in which the creation of artificial intelligence led the way to a race of powerful and self-aware machines that imprisoned humans in a virtual reality system (the titular Matrix) to be farmed as a power source. Occasionally, some of the prisoners manage to break free from the system and, considered a threat, become pursued by the artificial intelligence both inside and outside of it.

One of Morty's quotes when interacting with him in the lobby mentions the red pill and blue pill from the first Matrix movie. Said quote is actually recycled from the sixth episode of the third season of Rick and Morty, "Rest and Ricklaxation".

Mortal Kombat
Mortal Kombat is a media franchise centered on a series of fighting video games originally developed by Midway Games in 1992. The series has a reputation for high levels of graphic violence, including, most notably, its fatalities, which are finishing moves that kill defeated opponents instead of knocking them out. Controversies surrounding Mortal Kombat, in part, led to the creation of the Entertainment Software Rating Board (ESRB) video game rating system. Early games in the series were noted for their realistic digitized sprites and an extensive use of palette swapping to create new characters. Following Midway's bankruptcy, the Mortal Kombat development team was acquired by Warner Bros. Entertainment and reestablished as NetherRealm Studios.

MultiVersus features various references to this franchise. Scorpion's iconic catchphrase when using his spear attack, "Get over here!", is referenced by various Fighters, such as Batman, Wonder Woman, and Jake the Dog. When winning a match, Jake may say "Flawless victory. *cough* Yeah, I won.", referencing what the announcer of this series says after a match is won in every Mortal Kombat game. If the player Toasts someone while having the Default Announcer Pack equipped, the Default Announcer has a chance of saying "Toasty!", referencing the Toasty! easter egg from Mortal Kombat II.

Peter Potamus
Peter Potamus is a purple animated hippopotamus that first appeared in the 1964–1966 animated television series The Peter Potamus Show, produced by Hanna-Barbera and first broadcast on September 16, 1964. The Peter Potamus Show was divided into three segments: Peter Potamus and So-So, Breezly and Sneezly and Yippee, Yappee and Yahooey. The main segment featured Peter Potamus and his diminutive sidekick So-So the monkey. Episodes generally consisted of Peter and So-So exploring the world in his hot air balloon, which was capable of time travel at the spin of a dial. When faced with a precarious situation, Peter uses his Hippo Hurricane Holler to blow away his opponents.
