Firestar has the ability to tap into Earth’s electromagnetic field and convert it into microwave radiation emissions, which she can utilize in different ways. She can fly at great speeds, so all but one of her cards allow her to move around. By emitting microwave heat she can focus several attacks on a single target. Or she can manipulate microwave energy to perform extra Heroic actions.
