Frobisher

The Whifferdill Frobisher (formerly known as Arvan Taklu, later Bish) travelled with the the Doctor in his sixth and (briefly) seventh incarnations.

Early Life
He was once married to another Whifferdill named Francine. Francine left him as she believed she was a better detective. (source?)

Travels with the Doctor
Living as Arkan Taklu, he came across the Doctor when Dogbolter placed a bounty on the Doctor. After infiltrating the TARDIS, instead of turning the Doctor in for the money (even though the TARDIS interested Dogbolter more), Tarklu decided that he liked the Doctor and helped him to escape yet still get the bounty money which they split evenly. (DWM: The Shape Shifter) He then joined the Doctor on his journeys. He assumed the name of Frobisher because he felt that it sounded British and thought that the Doctor would like that. A this point he also settled on the form of a penguin. He saved the Doctor from drowning in the sea by hoisting him onto a rock. (DWM: Voyager) When the Doctor picked up Peri again after she had taken a break from him. (DWM: Time Bomb) Occasionally, all three would travel together as a trio, though Frobisher would take breaks too. During one, he took on a case to investigate Arthur Gringax. (BFA: The Maltese Penguin) After she had left the TARDIS, Frobisher and the Doctor would visit Peri Brown's descendants several times. (DWMS: The Age of Chaos)

Following an adventure with the Doctor, who had regenerated recently that involved the Ice Warriors, Frobisher decided to stay on the luxury planet A-Lux. (DWM: A Cold Day in Hell)



Life after the Doctor


Frobisher ran a bar later, having morphed into the form of a human. He met the the Doctor there but did not recognise him as he had regenerated since they both last met. He talked with the Doctor trying to find out why he looked so sad. When a robot called Zalda entered the bar, threatening to blow herself up, the Doctor convinced her out of it. Frobisher then called for drinks on the house. When everyone had left the bar apart from his wife Caralla who worked there had left, he morphed back into his penguin form. (DWM: Where Nobody Knows Your Name)

Forms
Frobisher's originally appeared as a pale yellow humanoid, three to four feet in height, with an egg-shaped featureless head, wearing spectacles. Inside the TARDIS, he somehow managed to change into the central console of the TARDIS console. After Francine left him he adopted the form of a penguin as she had been fond of that shape. He did this to remember her. In order to pretend to have captured the Doctor, he assumed with shape, and later that of W.C. Fields. Traveling with the Doctor, Frobisher later adopted the shape of a penguin almost all of the time. (DWM: The Shape Shifter)

He temporarily took on the form of a the Doctor again in order to investigate a murder. (A penguin detective would be shocking.) (BFA: The Maltese Penguin) On two occasions he morphed to extend his arms to perform strong punches. (DWM: The Shape Shifter/Frobisher's Story). Frobisher later developed Mono-Morphia, this prevented him from shape-changing for some time. (DWM: Genesis!) He temporarily turned into a muscular barbarian-style Near-Human on the primitive planet Actinon. (DWM: War-Game_

Frobisher later morphed into the form of a big cat to combat a Kymbra Chimera. He then changed into a dinosaur. (DWM: Changes). Frobisher stretched his penguin form to one similar to a hang-glider. He used this form to save Jamie McCrimmon. (DWM: The World Shapers)

Behind the Scenes

 * Robert Jezek voiced Frobisher with a Brooklyn accent.
 * The continuity of Frobisher's travels with the Doctor mostly doesn't mesh well with televised Doctor Who, other than Peri's reference in The World Shapers to having met Jamie McCrimmon in Spain. (Peri and Jamie's meeting had happened in The Two Doctors). A Cold Day in Hell occurs in a otherwise unknown period of the Seventh Doctor's life when he and Frobisher travel together without Melanie Bush appearing.
 * A mock interview with Frobisher appeared in Doctor Who Magazine after he had left the story. The article mentions Frobisher's unwelcome interest in Nicola Bryant, which caused tension "on set", though
 * It has been reported that a "Mr. Frobisher" will appear in Torchwood.
