After months of build-up, the latest Marvel Comics crossover event, Empyre, is finally here as the united Kree-Skrull Alliance targeting the Earth, with only the Fantastic Four and Avengers standing in their war.

Marvel has released a teaser video with writers Dan Slott and Al Ewing hinting at the five biggest revelations to come out of the debut issue, now on sale everywhere.

Slott and Ewing observe that Hulkling's position as Emperor of the Kree-Skrull Alliance will be threatened by someone from his own royal court while the heroes will be betrayed by two of their own as they brace for the epic conflict. Meanwhile, as the longtime Avenger frenemy Swordsman makes his return, the Kree select a new Accuser in the form of Carol Danvers as the coming invasion looms.

Originally slated to launch this past April, the ongoing COVID-19 pandemic' impact on the comic book industry delayed the crossover by three months while several planned tie-in special issues and miniseries were canceled. Now streamlined and shipping at an accelerated schedule, Empyre is poised to dominate Marvel's restored publishing schedule as the two biggest empires in the Marvel Universe unite against a common foe in Earth's Mightiest Heroes.
