At the Comic-Con in San Diego, Marvel Studios' chief Kevin Feige announced that two new 'Avengers' films will end Phase 6. The films include 'Avengers: The Kang Dynasty', which will be in theatres on May 2, 2025, and 'Avengers: Secret Wars' hitting the screens on November 7, 2025.

The announcement makes clear that the multiversal shenanigans of 'Loki', 'Spider-Man: No Way Home' and 'Doctor Strange in the Multiverse of Madness' are leading the Marvel Cinematic Universe to a cataclysmic crossover event to end all crossover events -- quite literally, it could reshape the fundamental fabric of the MCU from the ground up, reports 'Variety'.

It all revolves around a Marvel comics crossover miniseries from 2015 called Secret Wars, which evokes an earlier crossover miniseries from the mid-1980s also called Secret Wars. In the earlier iteration, every Marvel character imaginable is pitted against each other when a character called the Beyonder transports them all to a planet subtly called Battleworld.

It was a more-or-less baldfaced ploy to juice toy sales and is not particularly well regarded among fans.

According to 'Variety', the 2015 version took many of the same ideas but deployed them into a far more narratively complex storyline.

This time, the catalyst is the incursion between the main Marvel universe (Earth-616) and the Ultimate Marvel universe (Earth-1610) that causes the destruction of both.

In its wake, iterations of many Marvel characters find themselves living in a new, post-apocalyptic universe called Battleworld that is policed by every version of Thor in the multiverse called the Thor Corps and captained by Sheriff Strange.

Getting to this storyline, however, requires at least a few critical characters to make their MCU debut, especially the 'Fantastic Four' and their main nemesis, Victor Von Doom, as well as a character known as Molecule Man.
