In The Flash season 3, Cisco developed an attraction to Gypsy, a dimension-hopping bounty hunter from Earth-19 who tried to capture H.R. Wells.
Played by Danny Trejo, Breacher will force Cisco to “prove his worthiness” after finding out about Cisco’s relationship with his daughter Gypsy (Jessica Camacho) in The Flash season 4.
According to the episode’s synopsis, Breacher will take an immediate disliking toward Cisco and will decide to hunt him down. The Flash continues tonight with ‘Mixed Signals’ on The CW.
For the life of H.R., Cisco challenged her to a trial by combat and won.
