The ability to harness kinetic energy and use it, kind of like Gambit from X-Men. Or speed like the Silver Age Flash. He can run at the speed of light, and "lend" his speed using the Speed Force to other objects. He can also run through time itself.
Well heres an idea: If you have an Australian character, or even have them have Australian ancestry, you can give them Dreamtime powers. No listen, its a real thing in Australia, look it up, you can really get creative with it. The Dreamtime could be like a state that if your character can fall asleep or whatever, they can create illusions or whatever to fight.
