Jason Aaron's Avengers Era Concludes With EVERYONE Assembling

The synopsis information provided by Marvel reads, "UNITING THE AVENGERS, AVENGERS FOREVER AND AVENGERS OF 1,000,000 BC IN AN EPIC SAGA THAT FORMS THE CAPSTONE TO JASON AARON’S ERA ON AVENGERS! From throughout time and the far corners of the Multiverse, the Mightiest Heroes of All the Earths are assembling as never before for a battle beyond all imaging. A war that will take us from the prehistoric beginnings of an Earth under assault by the greatest villains who’ve ever lived to the watchtower that stands at the dark heart of the all and the always, where an army of unprecedented evil now rises. The biggest Avengers saga in Marvel history begins now."

Aaron's Avengers series began in 2018. While the heroes have had to face a number of different foes and challenges throughout the run, the current storyline sees Earth's Mightiest Heroes going up against Mephisto. Recent issues have placed the Avengers going back in time, where they've encountered a handful of different variants -- including a World War II version of Doctor Strange, a Ronin version of Ghost Rider and more.
