Update: The Flash Season 4 adds Neil Sandilands (The 100) as the DC villain Clifford Devoe, a.k.a. The Thinker, a metahuman with a mega mind who embarks on a season-long battle with The Flash. A true genius, he’s devised an intricate plan to fix all that he deems wrong with humanity.
Danny Trejo has also signed on to play Breacher, a feared bounty hunter from Earth-19 and the imposing father to inter-dimensional bounty hunter, Gypsy (Jessica Camacho). His mission is to prevent any inter-dimensional traveler from threatening life on his planet — especially his daughter’s.
The Flash Season 4 synopsis:
Barry Allen (Grant Gustin) lived a normal life as a perpetually tardy C.S.I. in the Central City Police Department. Barry’s life changed forever when the S.T.A.R. Labs Particle Accelerator exploded, creating a dark-matter lightning storm that struck Barry, bestowing him with super-speed and making him the fastest man alive — The Flash. But when Barry used his extraordinary abilities to travel back in time and save his mother’s life, he inadvertently created an alternate timelineknown as Flashpoint; a phenomenon that gave birth to the villainous speed god known as Savitar, and changed the lives of Caitlin Snow (Danielle Panabaker) and Wally West (Keiyan Lonsdale) forever. With the help of his adoptive father, Joe West (Jesse L. Martin), his lifelong best friend and love interest Iris West (Candice Patton), and his friends at S.T.A.R. Labs — Cisco Ramon (Carlos Valdes), C.S.I Julian Albert (Tom Felton), and an Earth-19 novelist named H.R. Wells (Tom Cavanaugh) — Barry continues to protect the people of Central City from the meta-humans that threaten it.
