Klaus (Andromeda Or Die)

From Tardis Wiki, the free Doctor Who reference

Klaus was a Bereznik agent and part of the assassination squad sent to kill Agent Twenty One of the Universal Secret Service, who was recovering from injuries he had sustained in Kiel Hospital. He impersonated a doctor treating Tchak's knife wound alongside Petrovitch in order to inflitrate the hospital. The squad soon encountered Agent Twenty Three with four stretcher guards, who were assigned to protect Twenty One, with a gun battle ensuing that lasted fifteen seconds ultimately killing all of the combatants.
