Yeamorg Warrior

From Tardis Wiki, the free Doctor Who reference

The Yeamorg Warriors were a warfare group of cyborg soldiers. They were not known as “the brightest bunch” and pursued the Doctor by tracking his TARDIS on a number of short trips around the planet when they encountered it whilst stocking up on supplies. They were rendered unconscious when the Doctor overloaded their brains. They left to be collected by the galactic law enforcement as in breach of Article 57 of the Shadow Proclamation. Their orbiting warship had been disabled by Amy and Rory. (COMIC: Finders Keepers)
