"The Flash" has cast Devon Graye as a competing Trickster, who will try to succeed the original and incarcerated Trickster, played by Mark Hamill.

The CW superhero series will introduce Graye as Axel, a young copycat of the con man Jesse James a.k.a. Trickster, in episode 17 of this season, according to ComicBook.com. The 27-year-old actor previously starred as the teenage version of Dexter Morgan on the Showtime series "Dexter."

Hamill will also make his debut in the episode, reprising the role he played in the CBS version of "The Flash" back in the early 1990s. He'll reunite with John Wesley Shipp, who starred as Barry Allen, a.k.a. The Flash, on that earlier version, and now plays Henry Allen, the father of the current speedy superhero played by Grant Gustin.

The CW announced Hamill's casting in December. The network described Hamill's character as a "new iteration" of the Trickster who is now "an anarchist terrorist con man serving a life sentence in Iron Heights." He will help Barry and Det. West (Jesse L. Martin) "foil the city-wide attacks of a wannabe Trickster eagerly following in the original's deadly footsteps."

Axel Walker, the wannabe Trickster, first appeared in "Flash" No. 183 in 2002. He took on Jesse James' identity when the original started working with the FBI. Axel stole all James' gadgets and weapons, and acquired even more later on. He ended up replacing James on the Rogues, under the leadership of Captain Cold.

The episode does not have an exact airdate yet. "The Flash" airs on Tuesdays at 8 p.m. on The CW.
