retcons 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 [in "Who is Donna Troy?"] George [Pérez] 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. Under John Byrne, Donna was retconned to be a mirror-image duplicate of Wonder Woman, created by the Amazon sorceress Magala using a spell to give life to Diana's reflections so that the young princess would have an age-appropriate friend. This duplicate is kidnapped by WWII Wonder Woman's nemesis, Dark Angel. Dark Angel forces Donna to undergo multiple "lives" that all end in tragedy and result in her resetting back to her beginning. Hippolyta and Wonder Woman attempt to rescue Donna, but Dark Angel destroys her rather than release her from her clutches. With help from Wally West, Donna is recreated as a golem, drawing from Wally's incomplete, Pollyanna-esque memories of her. Later, Dark Angel attempts to erase all memories of Donna from the various Hypertime realities, drawing Dark Angel into conflict with Donna, the Titans, and their alternate reality counterparts from the story Kingdom Come. During the battle, Donna is mindwiped and then reprogrammed with all of her old memories after she is made to relive her past lives. After Donna Troy is killed by a fleet of Superman androids reprogrammed by Brainiac, she is resurrected by the Titans of Myth, who seek to exploit her status as an "anomaly" from the world
