With Wally (Keiynan Lonsdale) choosing to leave Team Flash in the previous episode, two new characters that will have a recurring part to play with the team throughout the season are introduced in this week’s episode of the CW’s “The Flash”: Breacher, a bounty hunter played by action star Danny Trejo, and Ralph Dibney (Hartley Sawyer) who becomes the Elongated Man.

Breacher shows up on Earth 1 looking for his daughter Gypsy (Jessica Camacho) and isn’t happy to find she is in a relationship with Cisco (Carlos Valdes).

“Breacher is one of the most feared and dangerous bounty hunters in the multiverse,” executive producer Andrew Kreisberg says. “Couple his strength and power and ruthlessness with the fact that he loves his daughter more than anything in the world – which probably makes him more dangerous. There’s a clash between him and Cisco for Gypsy’s affection.”

When it came to introducing Ralph Dibney, Kreisberg said it had been on the show’s bucket list for quite awhile.

“Every once in a while someone would bring it up as sort of an episodic thing,” he says. “We thought that he was too big a deal. It’s Season 4, and shows can get stale, so we wanted to bring somebody in and really have them feel like something new and something different and something you haven’t seen a lot on television.”

One of the things that excited Kreisberg about introducing the show’s version of Dibny was it added a type of person into the fold that the team didn’t have: a jerk.

“The one thing we didn’t have on this show – because everyone is so likable – is we didn’t have a jerk,” Kreisberg added. “Harry is a jerk in a different way. We didn’t have somebody who was sort of a louse and crude and liked to drink. With so many of these characters, they aren’t who they are yet. Everyone is becoming the Green Arrow or becoming The Flash. We thought it would be interesting if he had a bit murkier backstory, and by the time he got to season whatever he’s the Ralph Dibny that everybody knows and loves from the comics.”

New episodes of “The Flash” are on Tuesdays at 8 p.m. on the CW.
