Wonder Twins.

Hey kids (of all ages), it's Saturday Morning Cartoon time again!

When Hanna-Barbera took over the animation license for DC Justice League comic book superheroes, they stirred-in a big dollop of SCOOBY-DOO to appease the killjoy parent groups. But the Meddling Kids and semi-anthropomorphic mutt didn't last long. The SUPER FRIENDS series was revamped, and they were replaced with actual superhero teens... Sort-of.

The Wonder Twins were aliens, wore costumes, had a blue space-monkey, and had what should have been awesome powers. Jayna could transform into any animal. Zan could shape-shift into any condition of water in any shape. Neither seemed limited my Conservation of Mass, and could take forms from ounces to tons as needed.

Problem was that they sucked at using their powers effectively. This was parodied in these Adult Swim interstitial segments... But they didn't have to work too hard. The Twins really were almost this idiotic on the actual Super Friends shows.
