List of Marvel Universes

The Marvel Universe is a multiverse canon. According to the Marvel Comics Database the "Multiverse is the collection of alternate universes that share a universal hierarchy; it is a subsection of the larger Omniverse, the canon collection of all alternate universes. A large variety of these universes were originated from another due to a major decision on the part of a character. Some can seem to be taking place in the past or future due to differences in how time passes in each universe. Often, new universes are born due to time traveling, another name for these new universes is an alternate timeline."Marvel Comics Database: Multiverse. (Accessed 06 January 2013) 
In her info post about major Marvel Universes and how they relate to Steve/Tony, tsukinofaerii explains the multiverse like this: 
The characterization of the same character in different universes can be anything from quite similar to very different, backstory, personality and other details can stay the same or be completely changed from one universe to the next. This has consequences for the fandom: Some fans might ship a a pairing or follow their favorite characters by following different canon universes, others might ship different characters in different universes and others might only be interested in one universe or follow the universe rather than the character.
The universe label is usually added to the header of a fanwork. AO3 has separate universe tags for some of the bigger universes.
A list of all the named and unnamed universes can be found at the Marvel Comics Database.

==Comic-Based Universes==
===Earth-616 (Main Continuity)===
Earth-616 is the primary continuity, in which most Marvel Comics take place. The universe is based on our reality and frequently makes references to real life celebrities, politicians and events. Technology seems to be a little more advanced than in our reality and magic exists.
Some of the major superheroes (those who often have their own regular titles) include the Fantastic Four, Captain America, Spider-Man, Iron Man, Thor, Hulk, Daredevil, Wolverine and Doctor Strange. 
The major superhero teams are the Avengers and the X-Men. Many minor teams exists and the membership of both teams has changed very often over the years.
The first Avengers team consisted of Iron Man (Tony Stark), the Wasp (Janet Van Dyne), Giant Man/Ant Man (Hank Pym), Thor (Don Blake/Thor), the Hulk (Bruce Banner). Joined in Issue #4 by Captain America (Steve Rogers). Over time nearly all the major heroes of the 616 universe were part of the Avengers team roster.
The X-Men are a team of mutant superheroes, formed by Charles Xavier, who trained young mutants to control their power and use them for the good of humanity and fighting against the rising anti-mutant sentiments in society. The first mutants he recruited were Cyclops, Iceman, Angel, Beast and Marvel Girl.

===Earth-1610 (Ultimate Marvel)===
Earth-1610. The Ultimate Marvel universe is an imprint that was launched in 2000. It basically "reset" many of Marvel's key titles from the beginning, starting over with a clean slate and showing the characters in high school and college, gaining their powers and encountering each other and antagonists for the first time. It "is considered a more modern reboot, with simplified backgrounds for most of the characters. Unlike many of the other continuities, it stands out very much on its own. Each arc can essentially be read as a stand-alone. Ultimates is also the origin of the black Nick Fury as played by Samuel L. Jackson (Nick is white in 616). Another notable change of race is Jan, who becomes Asian in 1610."
Characters who were updated include: Spider-Man (Peter Parker, who was succeeded by Miles Morales), Wolverine (Logan Howlett), the Hulk (Bruce Banner), Thor, Daredevil (Matthew Murdock), the X-Men, the Avengers, and the Fantastic Four.
Fans sometimes refer to the Marvel Ultimates universe by the shortened name ults. As with the Marvel 616 universe, Steve/Tony fanworks are incredibly prevalent. However, there are different tropes for Steve/Tony fanfiction in the Ultimates universe. Rivals to lovers, sickfic, and internalized homophobia are more common due to the source material.

The individual histories are essentially the same as in the main continuity, with less complexity and fewer dark themes." Unlike many Marvel lines, every Marvel Adventures comic is designed to tell a stand-alone story.
The lines published under the Marvel Adventures imprint were Avengers, Fantastic Four, Hulk, Iron Man, and Spider-Man.
