With CBS already locked into a series commitment for Greg Berlanti’s Supergirl, and a leading lady now found in Melissa Benoist (Glee), all eyes are starting to turn to other aspects of the series – including, the villains and, perhaps more importantly, the status of Kara’s famous, super-powered cousin within the show’s world.

A new report concerning the series’ development reveals the identity of the primary antagonist for the Supergirl pilot. In addition, within that same report there’s a sly reference that may (or may not) be confirmation that Superman will indeed exist in the context of this DC TV show universe.

Here’s the relevant excerpt from that update (brought to you by TV Line):

Kara Danvers née Zor-El will have her work cut out for her from the get-go, seeing as her adversary in the series pilot will be the DC Comics baddie Lumberjack. To that end, the CBS freshman is seeking a hulk akin to “Rory McCann, the 6-foot-6 actor from Game of Thrones” [to] play this “big, burly monster of a man, who has battled Kara’s cousin” — that’d be you-know-who — “in the past” and shows up to ascertain her level of power, on behalf of an unseen superior.

Currently, Lumberjack has yet to make an appearance on any of the existing DC series (Gotham, Arrow and The Flash), so it seems the CBS series may well indeed be getting to go its own way among the plethora of comic-book television currently on the air. But, what really gets us intrigued from the report is the line “who has battled Kara’s cousin.”

Does this line mean Lumberjack will have done battle with Superman (prior to the start of the series), thus meaning Kal-El does in fact exist within the context of the show? If so, what does this mean for his actual appearance? Surely it would be less than wise for CBS to have him pop-up even as an occasional guest star because it would potentially devalue Kara’s story, but the Kryptonian bond the two share would have to come into play at some point, right?

If Superman is included on the show, then it needs to aid the development of Kara’s tale. The last thing CBS should want is a Supergirl series that only gets people to tune in when Superman shows up on screen. However, if they were to bring the character into the fold, it surely would cause one heck of stir among the fandom.

Supergirl premieres this fall on CBS.
