The only thing that would give Kori an advance is her starbolts can go long range and she has shown to control their blast range. So in reality she doesn't need to be need him. Since she can use her starbolts to drain but that's if she can even give a super attack on him. Kori doesn't have a big ranking in feats. So this really go about special attack both do have special hearing. I mean the only comparable strength would be Donna. And Donna isn't on the level of Wonder Woman. Wonder Woman and Superman are the two strongest Dc people. This is why Dc often has the two end in a draw.
