Chaser
From Tardis Wiki, the free Doctor Who reference
Chasers were target-seeking rockets employed as weapons by the Astrans by 2065. An Astran flying saucer contained at least three Chasers.
After the Kapt of one Astran space fleet orderd Chaser 1 and Chaser 3 to be shot after the Fireball XL5, the pilot surrendered, at which point the Astrans called off the Chasers and took Zodiac prisoner. (COMIC: Colonel Zodiac Disappears)
