Nice that you sort of used the New 52 costume that Wonder Woman wears and give it to Donna Troy. I still prefer the original iconic costume on Diana that she has worn for years, over the New 52 costume.
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
and I think everyone's had enough stupid Batman cartoons, and YJ was just getting good as was green lantern and what does CN do, the replace it with that new batman show and a Candid Camera-esque Teen Titans rather than continuing from Calling All Titans and Things Change.
Cool design! And yeah, I dunno what to make of Cassie yet. Donna, with a simplified origin as merely an amazon handpicked by Wonderwoman to be her apprentice, may have been a better choice, especially with those funny little DC shorts involving her, Batgirl, and Supergirl these days lol
