InSupergirl ( 2005 ) # 32by Kelley Pucketand Ron Randall , Kara faces Dolok , a time - traveling baddie , fifty years in the future . Although she carries a bass hatred for Dolok , she knows that he wields a gadget that make him capable of jumping back through sentence when threatened , potentially give her the one dick she would involve to preserve Thomas . During their encounter , Dolok indeed jumps back in clock time multiple meter , only to find Supergirl somehow always there to exhaust him   She easily overcome him and choose his gimmick . However , it ’s then bring out that since Supergirl know of Dolok ’s capableness , she had literally spend at least   thirty   year waiting in blank space just where she planned to face him later . Supergirl had guaranteed that whatever clock time Dolok jumped to , she would be there . While readers might be lure to thinkSupergirl becoming more fell than Superman is late , this risible shows Kara has always been at least a little minute ruthless .

This is a sincerely hardcore move on Supergirl ’s part . expend at least three decennium of her lifetime waiting around in the same dapple in space is something that expect truly unbelievable self-will . However , it ’s also something that Superman could never do . He would never be able-bodied to push aside citizenry in motive for so long , specially with howSuperman ’s   enhanced hearing would ensure he discover every war cry for help . He ’s also not ruthless enough to commit decade of clip to beat the same person as they pass over backwards through prison term in a desperate endeavor to escape him . Kara is able-bodied to nerve herself and wait for upwards of thirty   year because of her determination to ensure Thomas ’s survival , but Superman would never forsake every other tike for decades just to bring a single one back from the utter .

finally , even though she now hold the power to reunite Thomas with his parents , or even to save her home planet of Krypton , Kara decides that rewriting history would be stoop to Dolok ’s tier , and she destroys the gimmick . Still , those years she spent in space show that sometimesSupergirlis willing to use her Kryptonian advantage for much darker mean thanSupermancould ever dream of .
