Black Vulcan and Wonder Woman are among the SuperFriends who go off to look for their three missing teammates - two of whom are Black Vulcan and Wonder Woman.
Wonder Woman, while in space, uses her radio to contact what she thinks are the other Super Friends. However, while she is wearing a helmet allowing her to breathe in a vacuum, her radio is outside the helmet, and the sound of her voice shouldn't be able to travel through the vacuum.
After Wonder Woman, Hawkman, and Black Vulcan are rescued from Toyman's artificial planet, the three are not seen in Green Lantern's protective field as they head back to Earth.
Black Vulcan says two of his lines with Hawkman's voice.
Batman and Wonder Woman are both shown "streaking into the night sky", even though neither of them has the power to fly. (The Flash is also shown flying, but he does have that power in this series, unlike his comic book counterpart.)
