With Arrow, The Flash and Legends of Tomorrow on its schedule, The CW has had a lot of material to build it DC TV universe. Fortunately for fans, it was announced last month that The Flash and Supergirl will cross over later this month when Barry Allen makes his way to National City. This now opens up the door to the Scarlet Speedster to team up with other protagonists from Supergirl’s world, like Superman (if he ever shows up), Martian Manhunter, and maybe even the Legion of Super-Heroes, a team of teenage crimefighters from the 31st century whose existence was revealed last night. Seeing fellow time-travel The Flash join forces with them is an especially exciting prospect, which begs the question: will we indeed see the Scarlet Speedster team up with the Legion of Super-Heroes?
To bring everyone up to speed, three weeks ago in The Flash episode “Welcome to Earth-2,” Barry Allen, Cisco Ramon and Harry Wells traveled to Earth-2 to rescue Wells' daughter, Jesse Quick. While going through the portal, they caught Speed Force glimpses of the multiverse, including shots of Kara Zor-El, Gorilla Grodd and John Wesley Shipp’s ‘90s Flash. The last vision was of a Legion of Super-Heroes flight ring, but because the focus was on Earth-2, no more context was provided.
Fast-forward to last night’s Supergirl episode “Solitude,” where Kara and Jimmy James Olsen traveled to the Fortress of Solitude to get information on defeating Indigo. While there, viewers saw some of the items Superman has on display in his Arctic hideout, including - you guessed it - a Legion of Super-Heroes flight ring. It’s actually the same one that Barry saw, as you can see if you gaze closely at their stands.
With those two moments, the idea has been planted that Flash and the Legion could one day cross paths. It hasn’t been officially confirmed whether Supergirl takes place on a separate Earth from The Flash’s, but the crossover episode is titled “Worlds Finest” (note the lack of apostrophe), and Barry glimpsed Kara while traveling through the multiverse portal. So it’s more likely that’s the case than not, and working under that assumption, that means that if Barry were to fight alongside the Legion of Super-Heroes, he would need to run over to the Supergirl Earth. Easier said than done, but hey, at least that’s an option now, whereas last TV season had a one-world limit. The Flash also has a connection to the Legion in the comics through his granddaughter, who serves on the team as XS, so that’s another albeit small reason to connect them on the small screen.
So yes, the possibility of Flash teaming up with the Legion of Super-Heroes on Supergirl, whether it’s in the present day or the 31st century, is exciting. However, it probably can’t happen anytime soon. It’s impossible for such a team-up to occur this season, at the very least. The Flash is resolving the conflict with Zoom, while Supergirl is dealing with Non and his Myriad plan. Assuming The Flash and Supergirl return for new seasons this fall - the former almost certainly will, though the latter’s not quite as certain - maybe that time-and-world-spanning crossover would work alongside whatever new storylines are in effect. As a one-episode story, it’s doable, but remember that these shows can’t have the same interconnectivity that The Flash has with Arrow.
All this being said, before we get Flash to work with the Legion of Super-Heroes, Kara needs to have at least one adventure, if not several, with both Barry Allen and then the Legion. That should be easy enough to do since the Legion has a good relationship established with Superman; they don’t give those rings to just anybody. Once the Girl of Steel establishes a rapport with them, then she can set up a meet-and-greet with Flash, and all of them can take on some galactic threat keen on destroying Earth. You know, the usual stuff.
DC also probably wants to wait and see how this first crossover between The Flash and Supergirl goes. These two heroes working together is sure to draw in bigger ratings and viewership for Supergirl, but if it exceeds their expectations, then they’ll want to kick things up a notch, and what better way than with pairing Flash and Supergirl with an entire team of superhero from the future?
Whatever the future holds in store for these multi-network DC crossovers, that Legion ring allows for the superhero team to make their second live-action television appearance (the first being on Smallville), and if CBS and The CW plan on continuing these DC team-ups, then seeing Flash and the Legion of Super-Heroes together in this multiverse is more than just a speculative scenario; it’s a legitimate possibility.
New episodes of The Flash resume Tuesday, March 22 at 8 p.m. EST on The CW, while Supergirl’s next episode, “Falling,” will air Monday, March 14 at 8 p.m. EST on CBS. In the meantime, let us know if this team-up interests you.
