When The Flash returns for its fourth season, it will have a guest star unlike any other, with the arrival of film legend Danny Trejo.
In an interview with Entertaiment Weekly, executive producer Andrew Kreisberg teased the debut of Trejo's character, Breacher.
As he explained, Breacher's appearance will have an interesting impact on both his daughter, Gypsy (Jessica Camacho), and her "long-distance" boyfriend Cisco (Carlos Valdes).
"Well, we just thought it would be a great episode." Kreisberg explained. "Gypsy and Jessica, 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."
