Kid Flash came out of retirement to fight in the Crisis on Infinite Earths, and was hit harder than anyone when the heroes found Flash's costume and ring and realized that their compatriot was dead. However, even though a blast from the Anti-Monitor reduced Wally's top speed to that of sound, it cured him of his metabolic malady. This, combined with the desire to honor his mentor and friend, caused Wally West to discard his Kid Flash identity and, instead, adopt the name and costume of Flash. However, after fully accepting that Barry was not returning, West removed a mental block, unlocking his true powers. This made him just as fast as Barry Allen and at one point. He also acquired unique abilities such as sharing and stealing speed, and accessing the speed force itself, allowing time travel. When it was eventually discovered that Barry Allen was, in fact, alive, Wally took on his own version of the Flash costume, fighting alongside Barry Allen, Bart Allen (Impulse or for a time Kid Flash).
