H. Dicken
From Tardis Wiki, the free Doctor Who reference
Dicken was a 22nd century Earth miner.
When the Gangers became independent, he was initially coaxed into fighting them, but later accepted them when they had a change of heart. (DW: The Rebel Flesh/The Almost People)
He eventually met his demise when he sacrificed himself by locking himself in the passageway while trying to stop the Ganger Jennifer creature from breaking through to the gang and the TARDIS. (DW: The Almost People)
