So i was seeing a little video on Youtube from the Watchtower database on how every DCAU (DC Animated Universe) show is connected to many other DC, Marvel and other TV shows, movies, and franchises. Along with examining similar universes to the DCAU and seeing how they could be interpreted as Elseworlds. Of course that video was made to coincide with the release of our Elseworlds storyline, but that made me think. How far does the Arrowverse multiverse lead? Some of this is just scraping up old rumors, but some of this could potentially be real. I'll also be using some of the evidence from the Watchtower Database's video to connect these things here. So lets find how far the multiverse is possibly by leaping down the rabbit hole.
So the first bit is the absolutely confirmed extension of this massive multiverse. The Flash, on CBS during the period of 1990-1991. For only a short amount of time did this series gain its fame, but it was absolutely confirmed as canon to the Arrowverse during the Elseworlds crossover where we got John Wesley Shipp's version of Barry Allen appearing. Even extending his world with the inclusion of new heroes as cameos and references that we didn't get in the show such as their Green Arrow, Stargirl, and a reference to John Diggle as the John Stewart Green Lantern of that Earth. It was short lived, but a welcomed inclusion.
Next we have more of them that are a little loosely connected. Both Geoff Johns and Salim Akil had said in interviews that the show Black Lightning, and the DCEU (Meaning Man of Steel, Batman v Superman, Suicide Squad, Wonder Woman, Justice League, and Aquaman at this time) are all connected. However there is no absolute confirmation of this one in an episode of the Arrowverse shows, so unlike the 90s Flash series, this one is simply speculation.
Now we have the case of things getting big, but highly speculative. So the way we connect to further properties is through Mr. Mxyzptlk. You see in the comic book in the main DC multiverse called Superman and Batman: Worlds Funnest, it is revealed that every adaptation of Mxyzptlk is the same one. (Same with the character of Bat-Mite, but come on, when is he ever going to be in the Arrowverse?) Anyway this means the version played by Peter Gadiot in the episode of Supergirl called "Mr and Mrs Mxyzptlk" is actually every version of Mr. Mxyzptlk. Meaning every adaptation of the DC Universe touched by a Mr. Mxyzptlk is connected to the Arrowverse multiverse possibly. Now is when things truly get large. We have access to the DCAU which had a Mr. Mxyzptlk in Superman: The Animated Series. Then one in the main DC Universe. One also included in the TV show Lois and Clark: The New Adventures of Superman, the Superfriends cartoon series, Injustice, the Superman Returns movie, and the Superboy live action series. (Didn't count the version from the CW series Smallville as that one isn't a version that is a Fifth Dimensional imp and therefore doesn't lead to a connection in this multiverse theory) However this isn't even all of them. Just the Mxy connections, it goes deeper than this. The main DC Universe connection leads to Marvel comics due to the Marvel vs. DC crossover. Leading to the various video games made by Capcom such as Mega-Man and Street Fighter, the crossovers with various Disney XD characters such as Phineas and Ferb, and Jessie, and many, many more considering that it is Marvel and they go on with their crossovers. Next the DCAU leads to the Teenage Mutant Ninja Turtles, Freakazoid with the entire Looney Tunes franchise, and Batman: The Brave and the Bold. The latter brings a connection to every piece of Batman media that was shown before 2012. Leading to Scooby Doo, Supernatural, and the Green Hornet. Another thing that we get out of the connection to every Batman universe is the 1989 Batman movie which is a reference made by Mr. Mxyzptlk in the episode of Supergirl. Another bit of evidence to this theory is Mxy making a reference to the world of Marvel's X-Men. Particularly the alternate Earth that houses the movie X-Men from the year 2000. However even with these small references, it still is all speculation. Only part of this theory that could be correct is the fact that Mxyzptlk is every adaptation in one person. However we have no evidence of the Peter Gadiot version being a part of this whole thing except for him having the same abilities. So in the end, this massive world is just small.
So what do you think of this massive bit of speculation on the extent of the Arrowverse multiverse? Is it true? Did i miss anything else outside the Arrowverse that could be connected by this theory? Well comment if i did.
