Donna is on SBFFS and it was stated she was supposed to have started on YJ's first season but due to Wondergirl issues she couldn't, so it was stated that Donna joined and left the team during the 5 year gap even though they did not appear, Lt. and Srgt. Marvel also did as well.
Well if cartoon network wasn't being a butt (for lack of a better word) we'd get what we want, i'm sure Greg Weisman wanted Donna to appear on the show but for some reason she never appeared likely due to her wanting to either go solo or retire, infact he stated the Marvels and Donna's team deal so it happened. I want a few movies though one to bridge the gap and a Darkseid's Deadly Deal to close but thats not gonna happen
Also, in Wonder Woman 70s tv series was one wonder girl called "Drusilla" played by Debrah Winger
Actually, I was thinking about: The Superman/Aquaman Hour of Adventure, an early cartoon where they animated the teen titans.
