Wally's primary superpower is his ability to control the speed at which his body vibrates and to move and think at super-speed, which he uses primarily to run at super-human velocities. This super-speed is derived from his mainline-connection to the Speed Force: a vaguely-defined extra-dimensional and infinite energy source from which most speedster heroes gain their powers. Wally is widely considered to be the Fastest Flash, and is significantly faster than Barry Allen, and is confirmed to be the fastest being in the entire DC Multiverse.
