eh oh well just getting ready for my reactions and actions in the upcoming fight.<br/><br/>Only reason I ask is because the only thing I know of to weaken superman and supergirl is kryptonite and the red rays from the sun or something like that I think I remember reading an issue where Cassandra Cain was fighting supergirl with a sword that reflected the red rays of the sun thus taking supergirl's invulnerability not weakening her to death like kryptonite. oh well we will see and if anything we can edit I wanna fight!
