Three new faces are heading to Central City. During their panel at SDCC, the CW announced that they have cast Neil Sandilands, Kim Engelbrecht and Danny Trejo for the show’s upcoming fourth season.

Neil Sandilands has been cast as DC villain Clifford Devoe, aka The Thinker, “a metahuman with a mega mind who embarks on a season-long battle with The Flash that pits the ‘fastest man alive’ against the ‘fastest mind alive.'”

Kim Engelbrecht will play The Mechanic. Described as “a highly intelligent engineer who designs devices for Devoe. As Devoe’s right hand, she’s the truest of true believers who’ll stop at nothing to help him implement his plan to fix humanity.”

My boy Danny Trejo has been cast as 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 premieres Tuesday, October 10th at 8 p.m. Eastern/7 p.m. Central on The CW.
