Why I prefer manga to superhero comics:As an infant, Donna was rescued from a burning building by Wonder Woman. Until she wasn’t, because of the Crisis on Infinite Earths. Meanwhile, her Earth-2 counterpart was rescued by a fireman, her Earth-S counterpart wasn’t rescued at all, and her Earth-7 counterpart was rescued by the Anti-Monitor, who raised her to be Dark Angel, the evil counterpart to The Monitor’s Harbinger. Remember that, because it’s going to be important later. On the revised post-Crisis Earth, Donna was created by magic, from a reflection of young Diana/Wonder Woman to be her sister. She went on to become Wonder girl, then Troia, until her insane and prematurely aged son from an alternate future came to attack her as Lord Chaos. Chaos was defeated, but Donna gave up her Troia powers to ensure he would never exist. Then she became a Darkstar, then she regained her Troia powers. That’s until she was pulled out of reality by Dark Angel, who was trying to erase all Donna Troy histories except her own by tormenting Donna endlessly through mutiple realities. Dark Angel failed, and Donna was reincarnated as an infant who was rescued from a fire by Rhea, the queen of the Titans of Myth, who recognized Donna as one of a foretold twelve "seeds" who would save the Titans from extinction. Plus now Donna is somehow the living connection to the multiverse.
