Buzzer Edwards (Ganger)
From Tardis Wiki, the free Doctor Who reference
Buzzer was a Ganger cloned from the 22nd century Earth miner of the same name. He died when the Doctor's attempt to help the humans and Gangers negociate was interrupted by the human 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. (DW: The Rebel Flesh)
