The War of the Realms event hails from Jason Aaron, Russell Dauterman and Matthew Wilson and promises a battle unlike any the Marvel heroes have ever faced. When forces led by the infamous Malekith the Accursed set their sights on Midgard, the last remaining Realm not under their control, Thor and his allies face insurmountable odds as they fight to defend their world, culminating the story writer Jason Aaron has been building since he began his Thor run in 2013.

The event kicks off in April, with six issues spanning a total of three months. Marvel has teased that its scope will rival that of the universe-altering Secret Wars.
