The Raston Warrior Robot is an android that appears in the BBC sci-fi series, Doctor Who. Described as the most perfect killing machine ever devised, Raston Warriors are tireless, relentless and efficient. They appear to be silver humanoids and are seamless and without any distinguishing features. They have in-built launchers that propel long metal spears at high velocities that can easily slice through flesh and even Cyberman armour. They are incredibly fast, practically capable of teleporting, and are virtually indestructible.
