Requiem made a pretty strong impression in her debut appearance in Infinity Wars Prime #1 last week. As Marvel has been showcasing on Twitter all week, this new villain quickly and easily killed Thanos, cutting short the Mad Titan’s latest quest to gather the six Infinity Stones. In this issue, Doctor Strange gathers together the current stewards of the Infinity Stones, hoping to create a new Infinity Watch to protect the planet from Thanos.
