History
The heroes of Earth-Prime arrived at the pier, confronting thousands of Shadow Demons and began vaporizing as many as they could. Meanwhile, at S.T.A.R. Labs, the "geek team" began constructing of a bomb, with Wells deciding on the material of depleted promethium. Dinah Drake alerted the group at S.T.A.R. Labs that Shadow Demons were advancing on their position. As Frost and Rory prepared themselves for a battle, Black Lightning appeared, blasting a demon to oblivion, teaming up with the duo and defending S.T.A.R. Labs.

Background
"Fighting is useless. Surrender. Not today. Not ever. Oliver died so that we could continue to fight. He sacrificed everything for this new world, and we will not fail him. We will not fail this world."

- Anti-Monitor and White Canary

As the battle advanced, the Anti-Monitor. The heroes then began attacking the Anti-Monitor, though were overpowered by his advanced energy field and strength. The Anti-Monitor soon enlarged his body, with the heroes split into two groups and continuing their attacks.

The Flash was summoned back to S.T.A.R. Labs, with the team requiring his assistance in quickly assembling the pieces. Flash completed the construction in seconds, then brought Atom into the field to deliver the bomb. As Flash vanquished the Shadow Demons from the ground team, Atom flew at top speed to deliver the bomb to Supergirl. While the ground team was surrounded by Shadow Demons, Atom shrank Superman from the Anti-Monitor's grasp and advised Supergirl to throw the bomb directly at the Anti-Monitor. Supergirl threw the bomb, causing the Anti-Monitor to infinitely shrink into nothingness, achieving the heroes' final victory against the Anti-Monitor, and restoring peace to the multiverse once and for all.

Aftermath
President Shaw gave a live speech on Channel 52 about the Anti-Monitor's attack and Oliver Queen's sacrifice.
