A manifestation of death
in the tales of DC Comics The Flash
second series of comic books
to bear that name. The native americans
called it slow lightning
. The original Flash Jay Garrick
had encountered it before, as did Max Crandall
. It had been spotted before the deaths of Johnny Quick
and Barry Allen
. It tried to take Wally West
but missed and took his fiance instead. Then it chased him down to the end
of time, where death no longer has meaning. West was able to cheat this manifestation of death and get his girl back, but they now know what's "waiting for us all at the end of the race."
It is believed this story is a paradox of the DC Universe because fans of The Sandman know that Death cannot be outran. She takes many forms and The Black Flash is probably one of them. At the end of time it is chronicled she's the last to go when the universe is through, so Wally would have had to run past the end of time to avoid her.. or him or whatever.
An alternative way for a speedster to go is by way of the Speed Force. Old speedsters never die; they just reach terminal velocity.
