Jason and Bea can put up a fight, but ultimately they go down (and hard) vs. Team Adam; Firestorm can possibly evade/escape, but he won't win vs. BA or Isis (though he'll last longer against her than him). Fire is a non-factor in this battle, much as I like her.
EDIT: Actually, depending on circumstances, Isis might be able to take FS down faster, though local conditions/Jason's specific actions play a big part. Either way, he/Fire still lose, eventually.
