New images from the Jan. 16 episode reveal that the actor will play Anton Slater, the district attorney who in the classic DC Comics storyline prosecuted Barry Allen for the murder of the Reverse-Flash. Of course, on The CW drama, Grant Gustin's character is on trial for the murder (although not really) of Clifford DeVoe rather than his archenemy.

BARRY FIGHTS FOR HIS LIFE -- As Barry's (Grant Gustin) trial for the murder of Clifford DeVoe begins, Iris (Candice Patton) and Joe (Jesse L. Martin) must decide how far they are willing to go to keep Barry out of prison.

Valley played Christopher Chance, the bodyguard who protects his clients by assuming their identities, on Human Target, the 2010-2011 Fox drama based on the DC Comics character. He also voiced Superman in the 2013 direct-to-video animated movie Batman: The Dark Knight Returns.
