After the Polity successfully resists Union insurgency in Chicago, Migas works directly with the gen:LOCK team as they station in RTASA. He acts as what he calls an "engineering liaison", keeping a strong connection between gen:LOCK and the Anvil.
Migas is a man with dark skin, brown eyes and black hair and a matching mustache. He wears a white t-shirt underneath a blue and yellow zip-up short-sleeved jacket, big black and yellow gloves, gray trousers and a bulky tool-belt with a pocket full of tools. He also has a gray cap, black googles on his head, yellow headphones around his neck and a large tattoo of a skull on his right forearm.
Migas is a friendly, laidback, casual and somewhat goofy type who enjoys drinking and gaming, as well as getting his hands dirty. He is shown to not be very resentful or to hold grudges, and one of his first thoughts upon finding out that Chase is still alive is that he could "finally have a beer with that dead bastard". When finally meeting Chase face-to-face, though initially unsettled by the extent of Chase's condition, Migas quickly accepts him back into his life, simply happy to see him again.
