Complete story — includes the ending
In a flashback to the planet Maltus 10,000 years ago, Mar Novu experiments with time travel to see the dawn of time, only to accidentally end up in the anti-matter universe and unleash the Anti-Monitor. Following the multiverse's destruction, the Paragons attempt to find a way out of the Vanishing Point and save the multiverse, including Sara Lance, Barry Allen, Kara Danvers, J'onn J'onzz, Kate Kane, Ryan Choi, and Lex Luthor. With Jim Corrigan 's help, Oliver learns how to use the Spectre 's powers so he can rescue the Paragons and strengthen Barry's powers. With his increased speed, Barry drops off the Paragons on Maltus to stop Novu, but gets attacked by the Anti-Monitor and loses the others across the Speed Force. Though the team successfully stops Novu and Barry retrieves everyone, upon reaching the dawn of time, they learn the Anti-Monitor was released, regardless. With Oliver's help, the Paragons engage the god-like being and his shadow demons, holding him off long enough for Oliver to combine the Spectre's powers with the Book of Destiny to reboot the multiverse. Oliver succeeds, but he dies a second and final time, with Barry and Sara at his side. Note: This episode continues a crossover event that begins on Supergirl season 5 episode 9, Batwoman season 1 episode 9, and The Flash season 6 episode 9, and concludes on Legends of Tomorrow ' s special episode.
