Donna Troy is often noted for having had a number of complicated revisions to her origin. Writer Marv Wolfman recounted:I wrote the original Donna Troy origin story back in the first Titans run. She had never had one and was, in fact, not a "real" character (if you can call any of them real). She was a computer simulation of Wonder Woman as a girl. That story also named her Donna Troy and set up everything that followed. Unfortunately, after "Crisis on Infinite Earths" and the Wonder Woman revamp, we had to go back and redo it again as a brand new Wonder Woman being born on Earth could not have rescued the girl from the burning building. I wish we had been able to keep it as I think it's gone insane now. I just wanted a simple origin story. I came up with the original, and then "Who is Donna Troy?" George and I simply elaborated on what had been done, giving her real knowledge of who she was. I would love to say that everything after "Who is Donna Troy?" should be forgotten, but that's not the way continuity works, sadly.
