Buzzer Edwards (Ganger)

Buzzer Edwards (PROSE: "Equality Bill") was a Ganger cloned from the 22nd century Earth miner of the same name.

He died when the Eleventh Doctor's attempt to help the humans and Gangers negotiate was interrupted by the human Miranda Cleaves, armed with a circuit probe. Buzzer attempted to take it off her, but she electrocuted him to death. The Doctor was disgusted by this act, pointing out the fact that this Ganger replicant had a human heart, "and [she] stopped it." His death prompted the other Gangers to distrust their human counterparts and prepare to fight them for the right to live. (TV: The Rebel Flesh)
