Krypton showrunner Cameron Welsh says the Green Lantern Corps would be a "natural fit" for the Superman prequel series. The science fiction TV show already incorporates characters outside the Superman mythology, such as the time-traveling hero Adam Strange (Shaun Sipos). Hawkgirl is set to appear at some point in the future, too.
Developed by Man of Steel writer David S. Goyer and Damien Kindler, Syfy's Krypton is set on Superman's home planet two generations before his birth. The series follows the life of Superman's grandfather, Seg-El (Cameron Cuffe), as he fights to redeem the honor of his family. Seg-El must also contend with the coming of Brainiac, one of Superman's oldest villains. Described as the "collector of worlds," Brainiac is on his way to destroy Krypton in an effort to erase the Man of Steel from existence. Seg-El is warned of this conspiracy by Adam Strange, who has traveled from Earth to Krypton to preserve Superman's legacy.

At the Krypton panel at WonderCon (via IGN), Welsh talked about his plans for the series, which include going to Earth and the possibility of exploring other planets like Thanagar and Rann. In response to a fan's question about the chances of the Green Lantern Corps appearing on Krypton, Welsh said "That's something that would be a natural fit for us". DC Entertainment Vice President Dan Evans claimed that the Omega Man could actually appear on the series prior to the introduction of the Green Lanterns.
Like the Green Lantern Corps, the Omega Men are a cosmic team of superheroes. Counted among the latest iteration of the group is Kyle Rayner, one of the most prominent heroes to carry the "Green Lantern" name.
As a cosmic force tasked with patrolling the universe, the Green Lantern Corps does indeed seem like it would be a "natural fit" for the science fiction series. In fact, if they exist as a part of Krypton's universe, their presence in the story could become necessary, considering the threat posed by Brainiac. In the series premiere, Adam Strange explains that Brainiac has conquered numerous civilizations and has killed billions of people, which means that he's definitely something the Green Lantern Corps would be aware of. It would be interesting to see how the Kryptonian government would respond to alien interference - considering that the people of Krypton currently reject the existence of alien life.
The main obstacle in getting the cosmic superhero team on Krypton would be the upcoming Green Lantern Corps film, which is still in development. Some DC characters, like Arrow's Deathstroke, are off-limits depending on whether or not they're set to be featured in a film. It should also be noted that Krypton writer and co-creator David S. Goyer has been working on the script for Green Lantern Corps.
Krypton continues Wednesday, March 28 with ‘House of El’ on Syfy.
