"The Trickster is an anarchist terrorist con man serving a life sentence in Iron Heights who helps Barry (Grant Gustin) and Det. West (Jesse L. Martin) to foil the city-wide attacks of a wannabe Trickster eagerly following in the original's deadly footsteps. The episode will reunite him with John Wesley Shipp who went up against him as the original 'Flash' on the CBS version." (via ComicBookMovie)

The Flash executive producer Andrew Kreisberg said, "Having Mark reprise his role as The Trickster was on our original wish list when we were planning our version of The Flash. Christmas and Chanukah came early for us this year when he said yes! We are beyond humbled and excited to have him joining us for another round of deadly trickery!"
