Speed Force
After his return to the DC Universe, Wally is said to be even faster than before. Titans (2016) #5 issue, established that the Speed Force is inside Wally more than ever before. He can generate white lightning, which combines all the colors of the Speed Force. Also in DC Rebirth, Wally learned that he can sense when time has been manipulated, as well as listen to the Speed Force, which allows him to sense disruptions in the space-time continuum.
