Charlie Duffy
Charlie Duffy was a human colonist from Kandoka who got a job at Kerb!am as a cleaner. He had a crush on Kira Arlo.
However he wasn't happy with only 10% of the human population getting jobs, so he created deadly bubble wrap, which exploded on contact, and staged a movement where the deliveries of bubble wrap would kill people, in order for the machines to get the blame, which would lead to more humans getting work while putting automation out of business after so many deaths.
Charlie had not intended to fall in love with Kira, but he was frequently tongue tied when around her. He was genuinely devastated by her death, by the system.
Charlie was an expert in cybernetics, explosives and teleportation, which helped make his plan possible.
When the Doctor ordered the Kerblam Men to detonate the contents of their packages to foil Charlie's plan, Charlie was on the floor amongst them. Charlie was caught in the explosion and killed despite the Doctor's attempts to get him to leave with her. (TV: Kerblam!)
