Atrocity would occasionally attack Parker or O'Hara with its teleportation tentacles throughout their journey in the Alchemax building, until it eventually revealed itself and attacked Peter Parker. Atrocity was defeated, but would later appear again, attempting to kill Peter Parker at the same time the CEO was fighting Miguel O'Hara. Parker manipulated Atrocity into attacking electrified pillars, stunning it. Peter took this opportunity to remove Atrocity's tentacles, and send them through the time gateway. These tentacles were then used to drain the CEO of his powers. After both Atrocity and the CEO were vulnerable, they were knocked into the gateway together simultaneously, resetting the timeline.
