Davey (Invasion of the Bane)
From Tardis Wiki, the free Doctor Who reference
Davey was one of the Bane who attempted to conquer Earth in 2009. He posed as the PR officer for the Bubble Shock! factory in London and was under Mrs Wormwood, another Bane.
Wormwood sent Davey to kill Sarah Jane Smith, thinking she might pose a problem, but he failed. He was given to the Bane Mother, who eats the children that fail her. (SJA: Invasion of the Bane)
