From Super Friends Wiki:
In 1983, Hanna-Barbera began developing a new animated series based on the then-current version of the Teen Titans. It was "The New Teen Titans" and it was to follow the same universe of the Superfriends series. The members of the team included Cyborg, Wonder Girl, Changeling, Starfire and Raven. Wonder Girl would be the leader. Robin was not going to be a part of the series since he was already part of the Superfriends. The show never saw the light of day, however an anti-drug commercial sponsored by Keebler was released that featured the Titans. Plus another member is shown called the Protector, who was a new superhero to be Robin's replacement because Keebler was unable to use the character, as he was licensed by Nabisco.
