The multiverse is the hypothetical set of all universes as based on the setting of the same name from the Marvel Comics and the DC Comics, it is a collection of infinitely many alternate realities and dimensions.
Together, these universes are presumed to comprise everything that exists: the entirety of space, time, matter, energy, information, and the physical laws and constants that describe them. The different universes within the multiverse are called "parallel universes", "flat universes", "other universes", "alternate universes", "multiple universes", "plane universes", "parent and child universes", "many universes", or "many worlds". One common assumption is that the multiverse is a "patchwork quilt of separate universes all bound by the same laws of physics."
The worlds within the multiverse share a space and fate in common, and its structure has changed several times in the history of Earth Responsibly storylines.
Rapunzel's Universe (Main Timeline or "Justice Universe") - (TVA Code: World-001)
Since this plot served as the baseline universe, World-001 is the name for the main, mainstream Earth Responsibly universe, which is home to the majority of stories (mostly in real life) and characters, including original characters or fauna (from fictional, mythological, and real-life figures) and beloved characters or fauna (from Disney and Pixar, Assassin's Creed, Marvel Studios, 20th Century Studios, American Broadcasting Company, Sony Pictures, Capcom, National Geographic, and Lucasfilm). Sagas fall into two categories: Past and Present Incidents (or PaPRIn, set in the pre-2100s) and The Recollections of Queen Arianna (also known as TROQA, set in the post-2100s).
The main characters are varied; mostly it was Queen Arianna of the Corona Kingdom as both narrator and observer.
In 2026, Harry Osborn, the son of Norman Osborn/Green Goblin, dubbed this universe the "Justice Universe" since it is controlled by the Time Stone, which Doctor Strange now uses, and justice is defined as treating people fairly. A number of disciplines and philosophical subfields, such as ethics, rationality, law, religion, and fairness, are used to interpret what "deserve" means. By running courts and upholding their decisions in society and the environment. The state can seek justice under the Assassin Order, the Templar Knight, and the Hidden Savior/Monster Hunter, who turned against the main culprit, Abstergo Industries.
Wirt and Beatrice's Universe (or Post-Paleolithic "Corruption Universe") - (TVA Code: World-002)
In World-002, which Harry Osborn from World-001 dubbed the "Corruption Universe," corruption persists under the leadership of the Order of the Ancients, who were eliminated along with the Assassin Order and Templar Order. The planet has advanced technologically and magically, and prehistoric animals are still alive and used as weapons (unlike in most universes, they are now extinct). Despite not being dystopian, communist and self-centered authoritarian governments around the world turned paradise into a nightmare by establishing the New World Order. Characters from Cartoon Network, as well as some non-CN characters (such as Luz Noceda), call it home, and it is governed by the Power Stone, which Wirt now uses.
The main characters of this universe are Wirt, Greg, and Beatrice from the USA, as well as Elmer Michel Rasolomampionona from Madagascar.
Because humans and other hominids, such as elves and dwarfs, either never hunt them, domesticate or semi-domesticate some species, or are technologically limited by their presence, extinct animals in this universe are unique and have survived into the Holocene. Although there are still global riots, corruption, and climate disruption, animals migrate or adapt rather than collapsing, and this universe drastically alters human society. Beatrice from their parallel universe claims that these creatures are strategic assets rather than pets. According to folklore, the lack of reflection is associated with soullessness or intruders, which explains why some animals in Rapunzel's or our universe were unable to see to the parallel universe character or fauna's lack of reflection in mirrors or vision.
The following is a list of several creatures in Rapunzel's universe that are unable to see parallel universe individuals in person or that reflect off of mirrors:
White-lipped Tree Frog (only it feels presence and croaks to call others)
Nile Tilapia
All Suncus shrew species
All Damselfly species
All Dragonfly species
All Brine Shrimp species
Beagle (only it feels presence and barks to call their owner)
Horned Demon
Vampire
Ghoul
Macaroni Penguin
Stymphalian Bird
Hamerkop
Shoebill
Mediterranean House Gecko
Dogs, wolves, foxes, and panthers are employed as trackers; ground sloths, cattle, bisons, and sheep as living battering rams; elephant birds as tanky rams; mammoths and elephants with armored platforms as battlefield shock units; Deinotherium as a means of breaching infantry lines; and dire wolves and cave lions as terror weapons. The majority have guns, and occasionally they have AirPods or headsets to prevent eardrum damage close to the firearm. As a result, cities are constructed with moats and reinforced walls, fortifications and urban design advance more quickly, and open plains or infrequent wood warfare becomes exceedingly risky. In order to combat new threats and riots, modern mechanized warfare has been growing for ages.
By the 20th century, most militaries had replaced animals with tanks, blimps, and airplanes; nonetheless, certain countries continued to use megafauna for warfare in the jungle, mountains, or Arctic regions, and guerrilla organizations used ancient fauna as weapons when vehicles or robots failed. As Queen Arianna collaborates with William Miles, Shaun Hastings, Harry Osborn, Peter Parker, Thor Odinson, Loki Laufeyson, Ryu Hoshi, Akuma, Ken Masters, and others to defeat the World-002 weaponized fauna using World-001 creatures because most animals are born with magical abilities due to modifications made by the First Civilization during the Bereshit Era in the Paleolithic, Beatrice thinks, "Elephants but bigger, smarter, and far more dangerous."

Our Universe/Real Universe - (TVA Code: World-616)
Sacred Universe/MC Universe - (TVA Code: World-200)
Capcom-Marvel Universe - (TVA Code: World-045)
The MCU's multiverse centers on a universe sometimes referred to as the "Sacred Timeline" or World-777, which also describes a bundle of closely aligned, infinite timelines that do not lead to the emergence of a Kang variant.
The multiverse is believed to be explained by the eternal inflation system; however, the exact nature of its existence is largely unknown to its inhabitants.
