Doctor Strange and his crew might be trapped in the multiverse of madness, but over at Cartoon Network, some DC heroes are having some multiversal fun of their own. The first trailer just dropped for Cartoon Network’s Teen Titans Go! & DC Super Hero Girls: Mayhem in the Multiverse. The new TV movie brings the characters from both popular kid’s cartoons together to take on Lex Luthor when he defeats all of the heroes in the universe. The film is set to land at HBO Max on June 28.

“With the help of an ancient Kryptonian power, Lex Luthor unites the world’s Super-Villains to capture all of Earth’s Super Heroes, until … only the DC Super Hero Girls are left to stop the Legion of Doom. Our heroes must cross dimensions to rescue their fellow Super Heroes from the Phantom Zone, but a fortuitous wrong turn leads them to Titans Tower – where they find much-needed allies in the Teen Titans. The young Super Heroes discover their combined strength – and usual comic relief – are essential to save the day in this blockbuster event!”
