WARNING: The following article contains spoilers for “Success Is Assured,” the Season 6 finale The Flash, which aired Tuesday on The CW.
Thanks to the “Crisis on Infinite Earths” crossover, the very fabric of the Arrowverse was altered. After reality itself was rebooted, a new Earth-Prime was created, with changes to its continuity both big and small. Dead villains were brought back to life with new costumes and maybe even new abilities, Supergirl, Superman and Black Lightning all lived on this same world and new locations were added to the Earth-Prime map, such as Gorilla City and the Kingdom of Atlantis.
As DC fans know all too well, Atlantis is home to Arthur Curry, aka Aquaman. For the time being, there have been no direct mentions of Aquaman in the Arrowverse, which means it’s unclear if he is the one who sits atop the throne of the underworld city. However, Cisco Ramon has now visited Atlantis on two separate occasions which makes Season 7 the perfect place to introduce the Arrowverse’s version of Aquaman.
In the penultimate episode of Season 6, Team Flash devised a plan to rescue Iris from the Mirrorverse. But, in order to do that, they needed to build a device that was missing one key component. In order to build it, Cisco headed off to the one place where it could be found: Atlantis. Now, it’s almost a given that Cisco was bound to return from Aquaman’s home before the end of the season. However, due to the coronavirus pandemic, production on the series was halted, and Episode 19 served as an impromptu season finale. For that reason, Cisco was nowhere to be seen in the last episode because he was still in the middle of his trip to Atlantis.
It’s likely that Cisco would have returned in Season 6’s planned final three episodes once he finished his mission, but the early end to the season could now change all of that. With enough time and planning before Season 7 premieres in 2021, the producers of The Flash could alter their plan and finally take fans to Atlantis — or at least a part of it.
Once that happens, the series would finally be able to introduce Aquaman. There have been enough teases of Atlantis in the back half of The Flash’s sixth season that they are bound to pay off in some form. And what better way to do that than by finally bringing in Arthur Curry. These past few years have seen the addition of big DC characters such as Superman, Batwoman and just recently, Bruce Wayne (sort of). Therefore, there is no reason why Aquaman shouldn’t join the Arrowverse.
Airing Tuesdays at 8 p.m. ET/PT on The CW, The Flash stars Grant Gustin, Candice Patton, Carlos Valdes, Danielle Panabaker, Tom Cavanagh, Jesse L. Martin, Danielle Nicolet and Hartley Sawyer.
In the final few episodes of The Flash, Cisco left to visit Atlantis, making Season 7 the perfect place to introduce Aquaman to the Arrowverse.
