Joseph (Oh No It Isn't!)

Joseph (or Joseph the Porter) was the name of two porters of Bernice Summerfield, or possibly the same one.

Biography
Originally he was an android assistant to Victor Farrison, who sacrificed himself to save Bernice, the Seventh Doctor and Ace. The Doctor took his omnitronic processor, saying he would give it to someone who could salvage the personality from it. (AUDIO: The Dark Flame)

When Bernice took up residency at St. Oscar's University on the planet Dellah, Joseph was her robotic porter drone. He resembled a floating billiard ball who took messages and relayed information to her. (PROSE: Oh No It Isn't!)

It was later revealed that Joseph was in fact a spy for God and was a ship by the name of J-Kibb in "disguise". (PROSE: Tears of the Oracle)

After Dellah was destroyed and Bernice moved to the Braxiatel Collection, Irving Braxiatel gave her a new porter, also called Joseph. He was either based on the Joseph that Bernice had had on Dellah or on the omnitronic processor that the Seventh Doctor had salvaged from the Joseph android. (PROSE: The Doomsday Manuscript) He continued to work as Benny's porter and assistant during her stay on the Braxiatel Collection. He also assisted Hass by venturing to the Mims Sphere on a diplomatic mission. (AUDIO: The Judas Gift) Sometime in the future, Joseph was recovered by researchers constructing an exhibit based on Benny's life. He assisted Benny in destroying the museum's data on her, saving her life from the infected database which was trying to kill her. (AUDIO: Many Happy Returns)
