"Crisis on Infinite Earths" Crossover Will "Impact" 'Supergirl' in Big Ways

The annual crossovers for the DC shows on The CW are big events that leave lasting ripples on the Arrowverse. But this year’s crossover, “Crisis on Infinite Earths,” will have “more impact” on Supergirl than previous years, and there could be severe fallout after the crossover.

In an interview with IGN, Supergirl showrunners Robert Rovner and Jessica Queller previewed the fifth season of the DC series, which will premiere October 6. Rovner and Queller dubbed Season 5 “our Black Mirror season,” due to its focus on 21st century technology.

“We’re really looking at the role of technology in our lives and how people can use technology to escape what’s going on in their real lives instead of engaging with those aspects of their lives, and how our villains can take advantage of that,” Rovner said.

On the subject of the crossover “Crisis on Infinite Earths,” Queller told IGN that the crossover will have an impact on the Arrowverse and Supergirl in ways that the last few specials did not. “In general, it has more impact than our crossovers usually do,” Queller said. “It filters into the rest of our season where normally the crossovers are standalone.”

After its premiere in 2015, Supergirl became part of the crossover specials, beginning with 2016’s “Invasion!” and continuing with 2017’s “Crisis on Earth-X” and 2018’s “Elseworlds.” But the specials left little relevant story threads for Supergirl (Melissa Benoist) to deal with when her show resumed as normal.

That is now expected to change with “Crisis on Infinite Earths,” which fans predict will streamline the Multiverse into one single continuity. While Supergirl has inhabited Earth-38, her world may become part of Earth-1 (where Arrow, The Flash, and Legends of Tomorrow take place) after the crossover.

Or, she could die. In one of the most iconic cover illustrations in DC history, Superman carries the body of his dead cousin, Kara Zor-El/Supergirl in the cover of issue seven of Crisis on Infinite Earths.

Rovner further added to IGN that they will “tee up” the special in a way that’s “different” from Arrow and The Flash. “But it’s all interconnected, and the Monitor will be a part of that storytelling,” Rovner said.

The Monitor, played by LaMonica Garrett (Designated Survivor) is an alien born from the moon of Oa, the planet where the Guardians of the Green Lanterns reside. True to its name, the Monitor is omniscient and omnipresent, and was a principal character in Marv Wolfman’s seminal 1985 comic book miniseries Crisis on Infinite Earths, upon which the upcoming special is based.

The Monitor first appeared last year during “Elseworlds” and made additional appearances in the most recent season finales of Arrow, Supergirl, and Legends of Tomorrow. His appearance in Arrow was marginally bigger, as he appeared to pick up Oliver Queen/The Green Arrow, warning him that he will “not survive” the coming crisis. In a flashforward to 2040, Monitor returned to pick up Oliver’s wife, Felicity, who mentioned it’s been a long time since she saw her husband.

Supergirl will premiere October 6 on The CW. The series will also air the first episode of “Crisis on Infinite Earths” on December 8.
