Guero Davila was a pilot and drug runner for Epifanio Vargas and the first boyfriend of Teresa Mendoza.


Guero met Teresa when she was money changing and beat up her boss who groped her when she was speaking to customers. He then brought her into his world as his woman.

Guero and Chino were stealing from Epifanio by using a contact with the Federales to retrieve confiscated cocaine and sell it behind their boss's back. Guero is thought to have been killed by Batman following a drug drop on a short plane strip.[1]

It is later revealed that Guero didn't die after all, and that the DEA pulled him out of the plane before it exploded so that they could use him to take down the Vargas cartel. Their deal is that he won't get any time in jail if he talks.[2]

That's why they call him the "snitch".


Guero is impulsive, reckless, lives for the moment and can be rather jealous. He acts in his own self-interest, not thinking how his actions will affect his girlfriends Teresa and Leo (whom he dated before). Guero has a hero complex. He acts possessively toward Teresa and gets jealous of James after seeing that James has become important to Teresa and cares about her, which leads to some violence.


Guero is a Chicano male that is often seen with longer fair hair. He has a tattoo of Jesus Christ on his left shoulder. He also is slim and has light green eyes.


  • Leo: Leo was Guero's ex-girlfriend. Things ended badly and she swore that she would kill him if she ever saw him again. He uses her to try to get in contact with El Santo. She calls La Capitana on them, which leads to the near-death of Teresa. Leo's last words are to Guero, asking him to let Teresa go, before she is executed. 
  • James Valdez: Guero is threatened by James' presence because he understands James is a much stronger person who cares about Teresa and works with her. Guero saves James's life in the jungle and helps rescue him later in Chicago as he understands that James helped Teresa survive when Guero left her.
  • Teresa Mendoza: Guero is in love with Teresa, and they were together for about a year and he gave her the deed to his house as a gesture of love. She was hurt after finding out that he survived the plane explosion and left her behind. While she still cares for him, she doesn't seem to trust him completely. He never snitched on her while he was held prisoner by Camila and Cortez, enduring eight months of torture just to see her again. He died with his head resting on her lap, though she didn't notice the moment he died.  
  • Camila Vargas: He had once flown Camila out to the warehouse in Texas. Camila doesn't like him because he's a snitch for the DEA and orders James to kill him. Camila has Cortez imprison him and torture him for information about Teresa. She brings Teresa to his cell with the intention of killing him with death by a thousand cuts in front of her.

When Isabela Vargas entered the cell, he pressed the gun to her head and told her that he would kill her as Isabela held a gun on Teresa. Guero and Teresa make it to Tomás' clinic and Guero is patched up. While hiding from Cortez in the attic, his leg wound begins to bleed again. Cortez notices the blood dripping through the roof just as James and Pote arrive. Guero and Teresa are running to the car when Guero is shot in the side.
