10 Mind-Blowing Facts You Didn't Know About The Teen Titans Cartoon
7. Speedy Actually Shows Up With His Titans Design In Justice League
Even though the DCAU Teen Titans show never came to fruition, that hasn't stopped fans from theorising that the 2003 series is still a part of its continuity. There are a few problems that essentially disprove this theory - like y'know, the whole timelines not matching up and the creators of both series' stating that they're in their own, different continuities thing - but there are legitimately a few genuine connections between Titans and the various DCAU shows.
In an episode of Static Shock - which takes place in the DCAU - the titular Virgil Hawkins asks Batman where Robin is, only for the Dark Knight to respond by saying "he's with the Titans." Other episodes in that show confirm that the Teen Titans do exist in that continuity, and there are even a couple of nods to the 2003 series in Justice League.
Justice League's version of the Flash is Wally West, the former Kid Flash in the comics. He's voiced by Smallville's Michael Rosenbaum, and what makes this even cooler is the fact Rosenbaum appeared on Teen Titans AS Kid Flash.
Apart from that, the next biggest connection between the two continuities comes in Justice League Unlimited, where Speedy, Green Arrow's sidekick, shows up with his Titans costume on AND with actor Mike Erwin reprising his role from the same series. Coincidence? I think not.
