Interesting, I wonder if this might again suggest that NOT all Kryptonians develop the same powers under a yellow sun (We've never had a large enough sample to compare before), what with Chris having tactile telekinesis and now Flamebird apparently being pyrokinetic.
The old Phantom Zone series pre-Crisis introduced a magnificently terrifying pair of villains from the PZ, Az-Rel and Nadria who were a sort of nihilistic, sociopathic, Bonnie and Clyde pair. He was pyrokinetic and she was telekinetic even before they went into the Zone.
Their casual, almost disinterested trail of destruction on anyone they meet ("Convulse" "Burn") made them different from most and their loveless relationship was somehow DEEPLY creepy.
