-DC decided to give the character her own title and originally approached John Bryne to write the title but he turned it down so they came to Peter David who had his own ideas for the character which Bryne did not agree with.
-David ended up merging Matrix with a human Linda Danvers and much of his run explored religion and spirituality.
-He fought with DC to bring back Kara Zor-El for his Many Happy Returns arc which saw Kara reintroduced to DC. He had planned on having Linda/Kara/Power Girl team up and transition the title into "Blonde Justice" but DC canceled his run before he at the end of Many Happy Returns and decided to re-re introduce Kara in Superman/Batman.
