Director Jeff Wamester and writer Jim Krieg have done an impressive job with the three-part series, “Justice League: Crisis on Infinite Earths,” which encompasses the twenty-third through twenty-fifth — and final — stories in the DC Animated Movie Universe. As James Gunn prepares to take over DC movies, this series provides a spectacular conclusion.

The hero known as the Flash, voiced by Matt Bomer, takes center stage throughout much of the first part of the series. We learn about his origins, how he first met his wife, Iris (Ashleigh Lathrop), and how the Justice League — featuring Superman (Darren Criss), Batman (Jensen Ackles), Green Arrow (Jimmi Simpson), Vixen (Keesha Sharp), and Martian Manhunter (Ike Amadi) — comes together in response to the threat posed by Professor Ivo (Ike Amadi) and his android, Amazo (Nolan North). The twist is that Lex Luthor (Zachary Quinto) is responsible for giving Ivo a disease, leading to Amazo being unleashed.

After their initial mission, a man named Pariah (Nolan North) sends Flash to Earth-3, which is also featured in the Justice League: Crisis On Two Earths movie. However, instead of the Crime Syndicate moving to another world, an antimatter wave erases their reality, and the Flash’s counterpart, Johnny Quick, assists him in returning to his world.

The Flash faces another crisis on the day of his wedding when Harbinger brings him, Green Arrow, Vixen, and Green Lantern John Stewart (Aldis Hodge) to the Monitor’s satellite. The Monitor claims he can prevent the impending death that approaches.

The heroes gather on the satellite, including Earth-2’s Wonder Woman (Stana Katic), her aged husband Superman (Darren Criss), Hawkman (Geoffrey Arend), Robin (Zach Callison), Batman’s daughter Huntress (Erika Ishii), Dawnstar (Cynthia Hamidi) from the 30th century, Doctor Light (Erika Ishii), Mister Terrific (Ato Essandoh), and Aquaman (Liam McIntyre) from Earth-146. In the original DC Comics, this was a world where Superman existed thousands of years earlier than on Earth-1. This world resembles “Waterworld” and substitutes for Lady Quark of Earth-6.

My favorite heroes from Earth-4, the Charlton Universe, also appear. The Blue Beetle, Ted Kord (Matt Lanter), and The Question (David Kaye) are particularly well depicted.

The heroes are tasked with building towers to halt the dimensional wave threatening their world. Barry uses this opportunity to slow down time, allowing him to spend more time with Iris than usual and bond with Amazo. As Amazo passes away, the Spectre (Lou Diamond Phillips) appears to Barry, informing him that he must repay the time and warn the heroes that the Crisis has not yet ended. Before dying, the Flash appears to Batman when he is trapped on Warworld — which appeared in another DCU movie, Justice League: Warworld.

The wave of destruction continues, becoming evident as different realities fade away. This marks the end of the first part!

The joy of the original Crisis lay in the artwork and spotting many beloved heroes. In this installment, fans can identify characters such as Earth-1’s Atom, Atomic Knight, Batwing, Black Lightning, Blackhawk, Blue Devil, the Challengers of the Unknown, Creeper, Elongated Man, Firestorm, Guy Gardner, Hawk and Dove, Katana, Mento, the Metal Men, Metamorpho, Negative Woman, Nighthawk, Red Star, Red Tornado, Speedy, Star Sapphire, Swamp Thing, Tempest, Tomahawk, and Zatanna; Earth-2’s Doctor Mid-Nite, Hourman, Jade, Obsidian, Starman, and Wildcat; Earth-4’s Peacemaker; Earth-S’s Marvel Family; Earth-7’s Thunderer; the Freedom Fighters of Earth-X — a reality where the Nazis triumphed, including Uncle Sam, Doll Man, Ray and Black Condor — and many more.

The DC Universe owes a great deal to Marv Wolfman and George Pérez, whose “Teen Titans” and “Crisis” stories have influenced nearly every medium in which DC tells its tales. This project brought me back to 1985, when I was waiting for each new issue while feeling a bittersweet sadness, knowing that many of my favorite heroes would die and that the multiverse would cease to exist. Well, I was mistaken about that last part.
