The Flash has officially welcomed Thinker, Elongated Man, Hazard and Danny Trejo's Breacher into the fold with a new Season 4 trailer that offers a first look at each new character. Below, check out some screen caps of the new characters, starting with Breacher (Trejo).

Season 4 will welcome Machete star Danny Trejo as Breacher, Gypsy's father from Earth-19. Like his daughter, Breacher is also an inter-dimensional bounty hunter. He's guaranteed to make life difficult Cisco, who is currently dating Gypsy.

“Gypsy and Jessica [Camacho], they’re so tough and so strong. We’re like, ‘Obviously she came from somebody strong,’ and we just thought it would be a hilarious idea for Cisco, who’s managed to melt Gypsy’s heart, being unable to do the same with her father,” executive producer Andrew Kriesberg said in an earlier interview.

Team Flash will add another new hero to its roster: Ralph Dibney, aka Elongated Man, as played by Hartley Sawyer. According to the character's official description, he is “one of the Flash’s most iconic allies" and "is a fast-talking private investigator with investigative skills that rival those of Batman. Upon discovering he has the power to stretch his body to any shape or form, Dibny uses his new abilities to help Team Flash solve one of Central City’s greatest mysteries.”

Nevertheless, Elongated Man will have some tension with the Scarlet Speedster himself. "We’re altering his backstory a little bit. He and Barry have this shared, checkered past. The two of them don’t get along from the onset,” executive producer Todd Helbing explained in an earlier interview.

The Flash will get its first non-speedster villain in Season 4 when Clifford DeVoe, aka The Thinker, rears his ugly head in Central City. The Thinker, as played by Neil Sandilands, actually appeared at the end of the Season 4 premiere, where it was revealed that he had created the Samuroid to bring Flash back. According to the character's description, he is "a true genius" who has "devised an intricate plan to fix all that he deems wrong with humanity” -- and, apparently, that has everything to do with Barry Allen and the Flash. In his Flash debut, he sat upon a floating chair.

He appeared in the scene with Kim Engelbrecht's Mechanic, “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.”

The third episode of Season 4 will introduce Hazard, a metahuman with "the ability to give others bad luck, while cashing in the benefits for herself." As pictured above, Mike and Dave Need Wedding Dates star Sugar Lyn Beard will play the character, who is described as “perpetually down-on her luck and is convinced her life is cursed — until a freak accident changes everything. With the universe on her side, she poses a threat to both Team Flash and Central City.” In this glimpse of Hazard, it looks like Flash has slapped some cuffs on her, but -- knowing her luck -- she won't be held up for long.

Starring Grant Gustin as the Scarlet Speedster, The Flash airs Tuesdays at 8 p.m. ET/PT on The CW. The series also stars Jesse L. Martin, Tom Cavanagh, Carlos Valdes, Candice Patton, Danielle Panabaker, Keiynan Lonsdale and more.
