Mickey Barnes's backstory involves him fleeing financial troubles on Earth by becoming an "expendable" worker on a space mission. He and his friend Timo open a restaurant with mob money, which goes south, and they seek refuge on a spaceship heading to a new planet. Mickey, however, doesn't realize he's signed up for an expendable role, meaning he'll be tasked with dangerous, potentially lethal jobs, and regenerated if he dies. Mickey and his friend Timo are trying to make a living by opening a restaurant, but they use money from the mob to do so. When they don't pay the mob back, they face a grim situation, and instead of facing a brutal death, they apply to be passengers on a spaceship. Mickey, lacking skills like Timo (who can pilot helicopters), applies to be an expendable, unaware of the true nature of the job. Mickey is assigned dangerous tasks, including testing the air on a new planet for viruses and exposing himself to radiation for research purposes. If Mickey dies during one of these tasks, he's "reprinted" with his memories intact, making him the 17th version of himself.
