"Wonder Twins" is loosely based on a pair of 1970s DC Comics characters. In the comics, the Wonder Twins, Zan and Jayna, are introduced as superpowered sidekicks to more established heroes like Superman, Wonder Woman, Batman, and others in the Justice League. They each have their own superpowers, as well as the catchphrase "Wonder Twin powers, activate!"
The exact details of the upcoming HBO Max movie are still being kept under wraps.
