Jason Aaron's Avengers Forever is the cosmic-scale companion to his main Avengers run — a multiverse-spanning series bringing together Avengers variants from across the Marvel omniverse to battle the Multiversal Masters of Evil, a team of the most dangerous villains from different realities assembled by a version of Doom who conquered his entire universe. Aaron used the multiverse premise to comment on the Avengers concept itself, asking what the team means when its existence replicates across every possible reality.
