When Wonder Wonder Woman is done right, she's successful. There's no doubt in my mind WW could carry her own animated series without Superman and Batman or other superheroes. She don't need some animated or cinematic universe either. However, Diana is much different than Ahsoka, Korra, and She-Ra. They're already apart of a successful franchise. Wonder Woman is her own franchise. Sure, she has the greater DC Universe, but that's more like a treat rather than something important to Wonder Woman.
