Cobaltikar 45

Cobaltikar was normally a peaceful planet with mineral reserves of Cobaltikar Ore which it traded. It was populated by robots that had started off as factory workers but who had evolved into a new species by the time the Doctor visited with Decky Flamboon. One of their kind, Cobalikbot Acorn Delta went rogue and was imprisoned beneath a replica of the Eiffel Tower that was bought in exchange for ore from a Brancheerian. (DWA: Tower of Power)
