HUDSON (Heuristic Universal Driver with Sensory and Orbital Navigation) is a classic Rolls-Royce equipped with artificial intelligence. He is the personal vehicle of Doctor 'Tiger' Ninestein, though is also used by Captain Kate Kestrel. While HUDSON resides in Hawknest and can be loaded into the Battlehawk, he is never actually used in missions by the Terrahawks. HUDSON's modifications include a phaser, being able to switch colour spontaneously (he refers to 'chameleon' being his natural colour), a tower for Zeroids to sit atop and he can drive himself, though his passengers can take the wheel should they need to. When he isn't transporting the Terrahawks from point A to point B on the road, HUDSON masquerades as Kate's manager, the elusive F. W. Runkin.
