VETAC

From Tardis Wiki, the free Doctor Who reference

VETAC Robots were created by the Haddron empire for protection. The first models were knight-like robots that weren't very efficient. A new and upgraded model of the robots attacked Santespri. They had many functions including a powerful fire arm concealed where its hand would be. These robots were ordered by Cruger to save Hans Kesar and him from the prison. (PROSE: Dreams of Empire)
