Marvel Extended Universe

The Marvel Extended Universe (MEU) is an American epic superhero franchise, created by Captain Worldbreaker and centered around a film series that began with the 2012 film Avengers: Earth's Mightiest. The saga quickly became a worldwide pop culture phenomenon.

The Marvel Extended Universe is akin to the format of the Star Wars franchise, and is sometimes described as a combination of both.

Format
Unlike the Marvel Cinematic Universe, or MCU, the Marvel Extended Universe centers around trilogies of films, the first three of which compose the Earth Prime saga. Each trilogy will feature a branch of the Xiomarian Alliance. The first trilogy features Masters of Earth (this universe's version of the Masters of Evil) as the main antagonist, while the subsequent films remains a mystery.

Also a significant difference between the MCU and the MEU is the format of solo outings of their heroes. While the MCU films are grouped into phases, with each hero having one film in each phase, the MEU films will also include solo outings in its Marvel Anthology line.
