Reuben Whormby
From Tardis Wiki, the free Doctor Who reference
Reuben was the head of the Fang Rock lighthouse and worked alongside Vince Hawkins and Engineer Ben. After finding out about Ben's death, Reuben went outside, where he was murdered and copied, formally, by the Rutan. When the Rutan took him over he killed just about everyone in the lighthouse, including Lord Palmerdale, James Skinsale, Adelaide Lessage, Harker and his colleuge Vince Hawkins.
