How about not getting frozen? Yeah an extra invincible move with frame advantage would be fine and good, but not being frozen would just be nice and consistent with the character. Green Arrow's Ice Arrow: sorry. Superman's Breath: no big deal. Arkham Asylumn air duct: too bad. Like if Green Arrow and Killer Frost were going to fight, Green Arrow would really be busting out Ice Arrows. Come on. Not whining that KF needs a lot of buffs, but it stinks to play the Ice Queen and get frozen.
