Flash (Barry Allen)
Eobard Thawne found a time capsule in the 25th century containing a costume of the Flash (Barry Allen) and with a Tachyon device amplified the suit's speed energy, giving himself speedster abilities. Reversing the costume's colors, he adopted the moniker of "Professor Zoom the Reverse-Flash" and went on a crime spree. However, the time capsule also contained an atomic clock, and to prevent a nuclear explosion, Flash pursued and defeated Zoom, hoping he knew where the clock was. Unfortunately he did not, but Flash later found the clock, detonated it safely, and destroyed Thawne's costume.
