Essence of the Speed Force
It tastes like lemonade with a healthy dose of lightning.
*You are now a living conduit for the Speed Force, giving you dominion over all forms of speed.
*At will, you may shift yourself into a higher state of speed, causing the world around you to seemingly slow down while you can move at greater velocities. You have total control over how much physics apply to you as you shift up and down in speed. This can range from dodging bullets to taking a brisk jog across a continent, and your maximum will only increase with practice and time.
*Your ability to sense and react to things around you is heightened to the point where you can kick into a higher state on practically instinct to dodge attacks or catch a falling object.
*Tying into choosing how much physics apply to your superspeed, you can choose how much force you hit with at super speed, and whether or not you cause damage by your mere motion.
*You can grant superspeed to (and take from) other living things, as well as increase and decrease the speed of vibrations in all matter around you. This can develop into full manipulation of vibrations with enough dedicated practice.
*Your superspeed can generate electricity as a visual effect, but you can learn to throw lightning from it.
*By vibrating your own molecules, you can learn to phase through solid matter.
*Eventually, you will be able to outrun even the concepts of time and death, and even break through the barrier between other worlds.
*You can choose whether or not your powers (plus the ones that you grant) require an increased food intake.
*While your reflexes will protect you at superspeed, you can dial your sense of time up and down, so that traveling anywhere or carrying a conversation will not feel like an eternity to you.
