Matías Caño is a supporting character who appears in the Bank of Spain robbery in Parts 3 and 4. He helps the gang out with melting and storing the gold and also guards the hostages and has been an associate of Bogotá for six years.
In his first appearance in the third episode, he is 'picked' as one of the 'volunteers' to work in the gold production area. He refuses to do it by saying he is 'no volunteer' which angers Nairobi and results in Bogotá dragging him downstairs to the other hostages' horror. It is later revealed that was all an act and that he is in on the heist and one of the undercover members hired to help the main gang out.
In Part 4, he is now guarding the hostages more and that is his main role while the main gang can focus on producing the gold and keeping guard on any threats.
He stays downstairs with the hostages and stands in front of them, holding his gun at all times. When Arturo Román caused a commotion amongst the hostages, Matías approached him to warn him but was disarmed by Arturo. However, Manila, one of the hostages, revealed herself to have been an undercover agent of the gang, and almost immediately disposed of Arturo by shooting him in the leg and lending Matías his gun back.
He is quite young, probably in his mid 20s and has short brown hair and hooped ear piercings. He wears the red jumpsuit along with everyone else and is equipped with a real gun.
He is shown to be a hard-working, loyal and funny guy.
Matías and Bogotá have been associates for 6 years. However, their relationship doesn't appear to be amicable. Bogotá was angry at Matías for pretending not to comply with orders in front of other hostages. He reveals that he has wanted to slam Matías' head against a wagon 6 times.
