Given his relationship with Robert Rodriguez, it may be more surprising that he didn't appear in the first season. However, it has been officially announced that Danny Trejo will be appearing in Season 2 of From Dusk Till Dawn as a new villain known as The Regulator:
"Austin, TX- March 11, 2015 -- El Rey Network and Miramax announced today that Danny Trejo (Machete, Machete Kills) has joined the sophomore season of Robert Rodriguez's "From Dusk Till Dawn: The Series." Trejo has been cast in the roll of "The Regulator," a horrifying agent of evil who has been summoned to perform a deadly errand. Trejo appeared in the "From Dusk Till Dawn" film franchise as "Razor Charlie."
Trejo has had a prolific career in the entertainment industry, yet his road to success has been hard earned and anything but typical, spanning imprisonment to helping young people battle drug addiction, to acting and producing. Trejo has starred in dozens of films including Desperado, Heat,the From Dusk Till Dawn film series, Con Air, Once Upon A Time In Mexico, the Spy Kids movies, Grindhouse, Machete, Machete Kills, Dead In Tombstone and Muppets Most Wanted. He can be heard as the voice of Skeleton Luis inThe Book Of Life.

He has also voiced characters for Cartoon Network's Young Justice and The High Fructose Adventures of Annoying Orange. He can currently be seen in the Super Clio Award winning Snickers commercial where he plays the blonde high school student, Marcia Brady.
Briana Evigan (Step Up 2) has also joined the cast of "From Dusk Till Dawn: The Series" as Sonja - an American expatriate working as a tattoo artist in a Mexican Mercado - who also has a sideline forging papers and passports out of her back room. The returning cast includes: D.J. Cotrona (Dear John, G.I. Joe: Retaliation); Zane Holtz(Holes, The Perks of Being a Wallflower); Jesse Garcia (Quinceañera, Sons of Anarchy); Eiza González (Lola: Érase Una Vez); Wilmer Valderrama (That '70s Show, To Whom It May Concern); Madison Davenport (Noah, Shameless); and BrandonSoo Hoo (Tropic Thunder, Ender's Game, Incredible Crew).
Season one of "From Dusk Till Dawn: The Series" centered on bank robber Seth Gecko (Cotrona) and his violent, unpredictable brother, Richard "Richie" Gecko (Holtz), who were on the run to Mexico when they encountered former pastor Jacob Fuller (Robert Patrick) and his family, who were taken hostage. Using the family RV to cross the border, chaos ensued when the group detoured to the Titty Twister, a strip club populated by culebras, snake-like ancient creatures who survive by drinking human blood. They were forced to fight until dawn in order to get out alive.
Season Two explores a new chapter in this supernatural crime saga that travels from Mexico to the edgy, tricked-out Texas of Robert Rodriguez. It also deepens and complicates the core relationships between the characters, while adding new faces and new dynamics. Season Two begins with our characters in their separate worlds - Santanico (Gonzalez) and Richie (Holtz) are outside Houston, living like Bonnie and Clyde; Seth and Kate (Madison Davenport) are scraping by South of the Border; and Freddie Gonzalez (Jessie Garcia) is protecting his wife and young daughter in a Houston suburb. And Carlos Madrigal (Valderrama) and Scott Fuller (Brandon Soo-Hoo) emerge from the Titty Twister, changed men. They will all come together once again - this time facing off against an even bigger threat.
