Davey (Invasion of the Bane)
Davey was one of the Bane who attempted to conquer Earth in 2009, apparently one of the children of the Bane Mother. Using an image translator device he posed as a handsome looking PR officer for the Bubble Shock! factory in London and was under the command of Mrs Wormwood, another Bane. Like 'Mrs. Wormwood', it is assumed that 'Davey' is not his real name.
As PR officer, he gave tours of the Bubble Shock! factory and scanned every person who entered so that their minds were copied and fed into the Archetype. Kelsey Harper liked him, stating she visited the factory to see him and constantly called him " themuffin". After Kelsey inadvertedly set off the factory alarms with her mobile phone, angering the Bane Mother, he was forced to shut the factory down and get everyone else. He revealed to a frightened Kelsey that the creature was his Mother and ordered her to be taken to Mrs. Wormwood. He tried then to seek the other intruders (Sarah Jane Smith, Maria and the escaped Archetype) but was fooled by the apparent male custom not to enter the female toilets.
Wormwood then sent Davey to assassinate Sarah Jane Smith, thinking she might pose a problem, ordering him to take Kelsey back to Bannerman Road as an excuse to gain access to the street. However he was defeated when Sarah Jane defended herself and the group with some repellant spray (its contents unknown though thought alien in origin) and he was forced to retreat. Upon returning to the Bubble Shock! factory, despite begging for another chance, he was given to the Bane Mother who eats the children that fail her.
