The CW's Arrowverse crossover event Crisis on Infinite Earths is shaping up to be the Avengers: Endgame of live-action DC comic characters. The giant crossover event, which will unfold across multiple episodes of the CW's Flash, Arrow, Batwoman, Supergirl and Legends of Tomorrow, features a huge cast of characters from CW's superhero shows past and present. And it recently added another iconic DC character in the form of The Spectre, played by actor Stephen Lobo, as producer Marc Guggenheim announced:

"Fans of the Crisis on Infinite Earths comic know the Spectre plays a pivotal role. We're thrilled Stephen is our Jim Corrigan."

Crisis on Infinite Earths is a storyline from DC comics that sees the multiverse in which the comics universe exists under threat of destruction. This means every earth that exists in every dimension will be finished if heroes from multiple realities do not band together to battle the cosmic entity The Anti-monitor, played on the show by LaMonica Garrett.

The Spectre is another cosmic entity in DC Comics that is sometimes referred to as the Spirit of God's Vengeance. That means The Spectre is several levels higher in terms of power than every DC hero combined. It is the Spectre's duty to maintain the scales of balance in the multiverse and pass judgment on those who wish to tamper with the limits set by the creator of the multiverse.

Lobo will play Jim Corrigan, who is the human host that The Spectre fuses itself to in order to walk among mortals. In the comics, when the Anti-Monitor embarked on his destructive mission, The Spectre shouldered the task of bringing together heroes from every reality to combat the threat. It remains to be seen whether we will see a similar guiding role adopted by The Spectre for the show, or if he will take matters into his own hands and assume his giant, cosmic form to kick some butt more directly.

In any case, the addition of Jim Corrigan makes the Crisis an even more epic crossover than before. Not only are heroes and sidekicks from all of CW's current shows participating, but we will also see the return of fan-favorite characters from past shows, including Tom Welling and Erica Durance reprising their roles from Smallville, the show that kickstarted CW's success with DC properties, Cress Williams as Black Lightning, Kevin Conroy as Bruce Wayne from Batman: The Animated Series, Burt Ward as Robin from Batman the TV show and Brandon Routh as a Kingdom Come version of Superman.

With so many important characters jockeying for position, fans' expectations will also be sky-high. There will be a great deal of disappointment if such iconic characters are only onscreen for a few minutes and then disappear without really adding anything to the plot.

The Crisis also promises to shake up the existing Arrowverse in unexpected and unalterable ways, with more than a few important character deaths being teased across multiple shows. It looks like when The Anti-monitor finally does arrive on his mission of doom, even the combined might of The Spectre and heroes across multiple dimensions will not be enough to protect everyone from his wrath.
