Grubber Vapps was a Human male Sailor who worked at 222 fishing trawler in the town of Bartyn's Landing in Lamaredd, until he was recruited by his friend the recently-appointed Security Chief Mix Liddell as one of his Seconds. In that capacity, Vapps helped Liddell fighting threats such as Byrch "The Padawan" Dyshkava and, later, continued serving as Liddell's trusted assistant and friend for forty years. During this time, Vapps, a swoop racer, also took part in illegal Cargo Track races. When Liddell retired, Vapps became the new Security Chief.
