Infinity Countdown Prime #1

A 2018 Marvel one-shot written by Gerry Duggan with art by Mike Deodato Jr., serving as the prologue to the Infinity Countdown event. Following the return of the Infinity Stones to the Marvel Universe, the issue re-establishes what the Stones are and sets the pieces in motion for the coming struggle to control them, touching on players such as Adam Warlock, Loki, and Ultron. Framed as a scene-setting prime issue, it bridges into the main Infinity Countdown miniseries.
