The Arrowverse is chock-full of craziness, opening up all kinds of doors for CW superhero fan theories to run rampant. Fan theories about Arrow generally revolve around the Season 5 finale, whereas fan theories about Supergirl and Legends of Tomorrow look ahead to future seasons, speculating on what’s to come.
Weirdly, The Flash fan theories are the only ones really focused on the present. Well, kinda. At least focused on the not-too-distant future, in the case of Savitar’s identity. Actually, not-too-distant in the real world, not The Flash timeline where the Savitar showdown actually takes place in 2024, and you know what, forget it. There are a lot of theories. And with so much lazy writing crazy stuff going on in each universe, any number of things could happen.
Let’s take a look at some interesting speculation about the future of the Arrowverse. Some are likely to come to fruition, and others are sheer lunacy. You be the judge.
In the Season 2 finale of DC's Legends of Tomorrow, the Legends join forces with a version of themselves from Doomworld to fight the Legion. It seems all of the "new" legends are killed, meaning that the remaining team consists of the same Legends we had from the outset.
/u/Kazoology, however, argues via Reddit that Mick is actually the Doomworld version of himself, not the pre-existing one. As evidence, they cite his newfound antagonism towards Snart. That definitely seems cool enough to be true.
YouTuber Jawiin theorizes in the above video that at the end of Season 2, the Legends are outside the timeline of the rest of the Arrowverse, stuck in their own equivalent of Flashpoint. That's why the 2017 Los Angeles they end up in has a ton of weird buildings. Oh yeah, and dinosaurs. He also hypothesizes that they'll fix the timeline, making the whole thing moot. In other words, what else is new.
One fan thinks Batman, Superman, and Wonder Woman are all dead (on Earth-1, at least). From /u/JoshJBell via Reddit:
“The most concrete reference to the existence on the trinity on Earth One is Rip Hunter’s line “I’ve seen Men of Steel die & Dark Knight’s fall”. So what if the team we’ve been following weren’t the first Legends? What if this was the second time Rip had gathered a team to take on Vandal Savage? What if Rip recruited Batman, Superman, & Wonder Woman to go fight Savage through time, but he killed all of them, so Rip had to resort to the B-team?”
This theory is super compelling, but also very bleak. If Diana, Clark, and Bruce all fell to Savage, Superman-flunkee-turned-Atom Brandon Routh is unlikely to fare better.
Convincingly, /u/ doctormisterio19 via Reddit argues that Ra's al Ghul actually wanted Oliver to kill and replace him as head of the League of Assassins. His argument mostly revolves around al Ghul's blurry motivations for destroying Star City, and a line about Oliver reforming the League in his own image, changing their definition of justice and swearing off killing.
The best part of /u/doctormisterio19's argument, however, are the many voice-to-text typos within it. Really good stuff. And maybe he's right. He may also be right that, alternatively, al Ghul's questionable motivations are simply a result of bad writing.
