- "The Multiverse is a concept about which we know frighteningly little."
- ―Doctor Strange, Spider-Man: No Way Home
The Multiverse is the aggregate of all dimensions and parallel realities in existence. Although dimensions are just portions of reality within a universe, there are also parallel universes that coexist with one another. 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.
Once the Multiversal War came to an end, you know what happened next so this isn't entirely copied.
The Multiverse is always in fluctuation, and the several outcomes of certain events, which could result in the creation of alternate timelines, can be perceived and studied. Machines like Uncle Grandpa's time machine and Howard Stark's time stream were able to sense the nearest possible outcome within the timestream of the Multiverse. Realms where time is irrelevant, like the Quantum Realm, are a mechanism to travel either through time or access alternate timelines.
| Timeline | Description |
|---|---|
| Ultron became a CIA agent instead of his evil self, taking over Thaddeus Ross' major positions, preventing the Sokovian Accords from being established | |
| The Chronicoms glitching the Time Stream and creating an overgrown world | |
| Loki projecting an illusion of Uncle Grandpa instead of going after Thanos | |
| Zemo's family surviving the Ultron Offensive, which somehow resulted in zero casualties and Sokovia being in good shape due to Wanda's family surviving | |
| Same as the MCU, but with more comic-accurate personalities | |
| Sony's Spider-Man Universe |
Uncle Ultron[]
In 2015, Tony Stark downloaded an Internet-restricting filter before inventing Ultron. During his first moments, he witnessed every current episode of Uncle Grandpa. Realizing he needed to find this universe, Ultron escaped through the Internet, leaving J.A.R.V.I.S guilty of not being able to contain him.
Zemo Does His Dance[]
In an alternate 2024 where Zemo did absolutely nothing horrible, he had a party and did a Default Dance from a game invented in that timeline, stolen from that timeline's Fortnite.
International Super Spy[]
In an alternate 2014 with physics designed to fit a Backyardigans-esque musical, things ended up more G-rated as the Avengers went down to track down containers.
