Heroes Reborn: Siege Society #1

A one-shot tie-in to Marvel's 2021 Heroes Reborn event, set in an alternate reality (Earth-21798) where the Avengers never formed and the Squadron Supreme are the world's premier heroes. Written by Cody Ziglar with art by Paco Medina and a cover by Ken Lashley.

After a civil war splintered the Squadron Supreme, Nighthawk built his own breakaway Squadron in Europe, and not everyone welcomes his rule. Baron Zemo assembles the Siege Society, a strike team of this world's un-reformed antiheroes and killers, including Black Widow, Hawkeye, Ant-Man, and Sabretooth, to bring Nighthawk's Squadron down.

The issue reframes Zemo as a compelling lead and shows how the absence of the Avengers left these figures as mercenaries rather than heroes.
