Cyberdorks

Cyberdorks are apparently a crappier version of the Cybermen that were created following the Cyberman-Borg War, when the Cybermen became more peaceful. Their basic function was to run call centers but they all went rogue and ran away. They have no weapons and the few that want to fight have to resort to jumping out at people from behind walls wielding primitive weapons. They all appear to have gone insane, which is why the Cybermen shut down the idea of 'peaceful Cybermen'
