As he mentioned, Breacher is Gypsy’s father, and it sounds like papa bounty hunter is none too pleased with his daughter taking up with Cisco.
It’s pretty obvious from Todd Helbing’s words to Collider that he enjoyed working with Danny Trejo and crafting the character he portrayed.
Poor Cisco; he’s finally dating the woman of his dreams and now he has to deal with her intimidating father.
And, since Gypsy is also a bounty hunter, I can imagine that she got most of her skills from Breacher, meaning that she and dear old dad may be even closer than your standard father and daughter, and that Breacher is even more likely to be protective of her.
