This is one of those characters every writer from the Post-Crisis NEVER wrote her right: first she was brainwashed, then suffered from schizophrenia, later killed, then showed up alive claiming her twin sister was the one killed and later it was found out she got somehow, with no explanation, killed again. Poor Ulla, nobody understood her, wrote her write or even portrayed her in a fine matter...
