- "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. For Oliver!"
- —Sara Lance to Mobius[src]
A battle occurred on Earth-Prime after the Paragons restarted the multiverse. It was the final battle of the Anti-Monitor Crisis in which the champions of the new multiverse were victorious against Mobius.
When the Paragons were attacked by Shadow demons and Ryan was subsequently rescued by Sara, he is taken to the Arrowcave and they all deduce that the Anti-Monitor is still alive, and Oliver’s sacrifice didn’t kill him.
Ryan and Ray realize that while they can’t kill nor destroy the Anti-Monitor because he’s made of antimatter, they can destabilize his form, and have him shrinking for eternity. A horde of shadow demons began to make their way to Star City. Dinah stays behind on Comms, while the other heroes gather to fight the army of Shadow Demons. 
When one shadow demon shows up, Frost asks Heatwave if he wants to take the shadow demon, Rory says "ladies first" to which Frost replies by saying "age before beauty". Ultimately, the shadow demon is then taken care of by Black Lightning who shows up to help. 
The Anti-Monitor tells the heroes that they are nothing but insects fated to be crushed by his heel. 
He goes to tell them that fighting is useless and asks them to surrender. White Canary says not today, and not ever. She then tells the Anti-Monitor that Oliver died so they could keep fighting. She continues by saying that Oliver sacrificed everything for this new world, and they will not fail him. 
The Anti-Monitor then makes himself grow to an unprecedented height, and he yells out that the Age of Heroes ends now. Martian Manhunter, Supergirl, and Superman all launch attacks from the sky at the giant version of the Anti-Monitor trying to buy Ryan, Ray, and Nash some time with building the bomb that will take care of the Anti-Monitor. 
Using his super-speed, Flash goes back to Central City and assembles the bomb. Nash tells him that now all they need to do is get it in direct contact with the Anti-Monitor once they've activated it. The Flash then speeds back to Star City and takes Ray with him to help out in the final fight with the Anti-Monitor. 
The Atom arrives just in time and saves Superman from being crushed, and gives the bomb to Supergirl; telling her to throw it like a girl.
Supergirl throws it and it makes contact with the Anti-Monitor which made him keep shrinking.
