Charlie Duffy

Charlie Duffy was a human activist from Kandoka who got a job at Kerb!am as a cleaner.

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 thousands of Kerb!am Men would teleport deliveries of bubble wrap to kill people, so the machines would get the blame, thereby eroding people's trust in automations and putting the systems out of business, whilst leading to more humans getting employed

Charlie had not intended to fall in love with worker Kira, but he was frequently tongue tied when around her; she seemingly reciprocated his crush on her. He was genuinely devastated when the Kerb!am AI system enacted it's revenge by killing her, in the same way Charlie had murdered other workers.

Charlie was an expert in cybernetics, explosives and teleportation, which helped make his plan possible.

When the Thirteenth Doctor ordered all the Kerb!am Men to detonate the bubble wrap in their packages to foil Charlie's plan, Charlie was on the floor amongst them. Despite the Doctor and Graham's efforts to convince Charlie to come with them, Charlie stayed on the floor and was killed in the explosion.

While his plan had failed, his actions had convinced Judy Maddox and Jarva Slade to reorganise Kerb!am to be more reliant on a human workforce. (TV: Kerblam!)
