Rio was an expert hacker who participated in the Royal Mint of Spain heist. During the learning process and preparation for the heist, he developed a relationship with fellow robber Tokyo despite The Professor's request for participants not to fraternize.
Rio and Tokyo's relationship had a direct impact on the heist, as it affected their behavior and caused them to make impulsive decisions. Following the conclusion of the heist, they eloped together and spent time hiding in an island, but Tokyo eventually desired to go somewhere else momentarily.
Left behind, Rio was found by law enforcement agents and captured. He was brutally tortured by Alicia Sierra and became the catalyst of a second robbery, the Bank of Spain heist, with the crew reuniting in an attempt to save him.
Rio was born in 1997, his nickname given by his mother was Rayo. At young age he became interested in computers, eventually becoming a hacker. In 2010 he engaged in multiple cyber-attacks, which were all done discrete as the police couldn’t track him.
He was called by The Professor to join the heist of Royal Mint of Spain. He developed feelings for his teammate Tokyo despite Professor's rule of "No relationships".
In the first day of the heist he hacked the security cameras and alarms of the Mint and redirected the to the hangar where the Professor hides. While accompanying Alison Parker, he had a fight with Tokyo which allowed Alison to grab her phone to delete the picture of her on Instagram. But the police hacked her phone and turned on her front camera, which took the picture of Rio. When the police identified him they started searching for his gang mates. Eventually they found about Tokyo as they entered the bank a few months ago.
Rio is playful, naive, and innocent compared to his fellow crew members. His younger age resulted in some problems, eventually causing the professor to kick it out if it weren’t for Tokyo to prevent it.
Throughout the series, Rio has been considered the "weakest link" of the squad due to his innocent and naive personality.
Rio is a very skilled hacker, having attacked multiple websites and being recruited as the tech expert for a very complicated heist. He is shown to have enough knowledge of the deep web to know where he can buy weapons. Rio is shown to be at least a bit skilled with weapons, knowing how to use them. As stated by Alison Parker, he doesn’t hold a weapon like a professional. He is supposed to be skilled in all the things the professor taught him and his fellow crew members, although some have never been shown.
- Tokyo: Rio has a romantic relationship with Tokyo, developed during their time at the Toledo Estate. He loves her very much as shown when he starts to really stress when Tokyo doesn’t call him. Although he did accept that she wanted to go to the city and wanted to have fun.
