You get one power EXCEPT it cannot be:
2. Enhanced durability or invulnerability
. You get all you want and protection. Flight and protection, what more do you need? Really I would even accept limited TK, I wouldn't need all the fancy stuff, just so long as I can pull stuff to me, fly, and stop incoming projectiles I'm happy.
Actually other powers would be fine if you could use them in various ways instead of just one. Why have multiple powers if you have one that you can multi-task with right?
Optic Blast becomes Speed Force Optic Blast: By shooting an object you can steal it's forward momentum and make it stop. It can still move, you just stopped it momentarily, albeit this would destroy some things outright at a given speed. Meanwhile you would be able to fly at the speed or slower of whatever speed you stole. You could also transfer your speed to objects gradually by shooting them. Thus you could propel a parked car across the street while you slow down at the same time.
