Clive Yorkin

"You know what they say, Kid Flash; if at first you don't succeed, try try again."

- Clive talking to Wally West

Clive Yorkin is a criminal who had meta-human powers in the Flashpoint Timeline. Upon regaining his powers in the current timeline, he went on a killing spree, determined to kill all the police officers who arrested him in Flashpoint, regardless of their now non-existing history with him.

Powers

 * Meta-human physiology: After transmuted by the Philosopher's Stone, Clive's body was altered, allowing him to access his powers via touch.
 * Decomposing Touch: By making physical contact with a target, Clive can infuse some of his genetic make-up into the said target. Upon which, it will cause the target's structural integrity to break down at an accelerated rate. For living organisms, they will decay into a mummified-state within hours and soon after be reduced to ash. For inorganic targets, they will decay instantly. This power can also be used defensively as even without direct skin-contact, any weapons used on him can instantly be dissolved.

Weaknesses

 * Cold temperatures: While Yorkin's power work at an accelerated rate, following the normal nature of decomposition, extreme cold like from Caitlin Snow's powers, can temporarily stop the progression.
 * Speedster blood: As a speedster's healing powers work in the exact opposite nature to Yorkin's powers, the latter's powers can be completely negated if he gets infused with the blood of a speedster. This was shown when Kid Flash cut his hand and phased through him, stopping him.
