In his first appearance he was just a professor who found out about Jay Garrick's speed and tried to synthesize his own formula, but it worked only for a limited period of time. He also created a formula to slow down Jay, turning him into "the slowest man alive".

In his later appearances his shtick was that his speed serum started deteriorating his own physique, up to the point when his lightning went blue and he became one with the Speed Force, disappearing. He later returned from the Speed Force as a sort of unstable speedster, consisting of pure Speed Force energy. The guy who freed him from the Speed Force, Johny Sorrow, asked him to kill Jay Garrick in return for freeing Edward. To do that, Clariss possessed the body of Max Mercury, another old speedster.
