1) The ability to stop time for seven consecutive seconds (a sub-power of chronokinesis).
2) The ability to run at 300 mph (low-level superspeed).
3) The ability to become temporarily impenetrable to blunt force for thirty whole seconds.
4) Above average strength able to lift three times your own bodyweight.
If I had to choose, I'd go with either the superspeed (300 mph) or the ability to stop time for seven seconds. I could use either or to not only avoid danger but to turn the tables on my enemy (ex. stop time to take a weapon from her and use it agianst her, be able to speedbliz enemies and dodge multiple attacks).
