Dibber was Sabalom Glitz's uneducated but sensible henchman from the planet of Salostophus in the galaxy of Andromeda.
Biography
Circa the year 2,000,000 Dibber accompanied Sabalom Glitz to Earth (which was known as Ravolox at the time). Prior to this visit, Dibber had spent some time in prison. Dibber and Glitz were hired by the Master to acquire Time Lord files stolen by a group of Andromedans known as the Three Sleepers. To do so, they had to disable the black light power system that powered Drathro, an L3 robot that protected the Three Sleepers and the data that they had stolen.
Before carrying out their plan, they were imprisoned by Katryca, warrior queen of the Tribe of the Free. During their escape, Dibber destroyed the black light system receiver with a grenade. Dibber and Glitz then made their way into Drathro's base built out of the remains of the London Underground, where they were able to convince the dying Drathro they had a black light power system on their ship, the Nosferatu. Drathro fell for their lies and followed them towards the surface with the Time Lord data files. Drathro collapsed and blew up, burning the files in the process. (DW: The Mysterious Planet) When Glitz and Melanie Bush were transported to the Doctor's trial to testify, Glitz at first thought Mel's capsule contained Dibber. (DW: The Ultimate Foe)
Accounts differ as to Dibber's activities after that point in his and Glitz's timeline. He may have been one of the members of the Nosferatu crew whom Glitz sold into slavery on Iceworld (DW: Dragonfire) although one account stated that Dibber had been killed before that. (PDA: Mission: Impractical) Another claimed Dibber was still alive and working with Glitz afterward. (NA: Head Games)
