Reyes is a Special Agent for the CPD, working as a tech specialist for Wilburn. He's witty but would rather not get involved in the field, however the death of the agents during this mission to take down Mariachi fuels that desire to come out of the station and follow. 

He began trying to work as a hacker, but just when he was getting started, the mass hack of The Jester happened, and he realized the game he was getting into was too dangerous. 

Reyes eventually joined the CPD under their Intergalactic Pursuit Cop division, not realizing this was going further from his skills with tech. He just wants to catch the bad guy and make them pay.

He then managed to get accepted into the detective division, which saw him work as a field agent initially. During his investigations and cases, he would find out about the killing at New Milwaukee, setting up his own theory board as a past-time.

Eventually Reyes was granted the position of tech specialist, and it was soon after that he began having a family. However things will get challenged for Reyes now, as Mariachi leads the department on a wild goose chase across the planet, even stringing Reyes along.
