Rutan scout A Rutan scout who later came to be known as Rupert the Rutan came to Fang Rock in 1969 . Due to a malfunction with its Osmic projector , the Rutan travelled back in time and split in two . One of the Rutans arrived in 1902 and was defeated by the Fourth Doctor , while the other arrived in 1822 and lived on Earth for over a century . History . Having studied all planet s in the Sol system , Earth was chosen as the best to serve the Rutan Empire ' s plot to destroy the Sontaran s . The scout was sent to Earth for reconnaissance in May 1969 . As it arrived on Fang Rock , the Rutan was caught in a paradoxical situation ; Anne Travers ' experiments with a version of the Rutan ' s osmic projector that had already travelled through time interfered with the Rutan ' s osmic projector and caused it to temporally malfunction and travel back in time . In a process similar to binary fission , the malfunction caused the Rutan to split into two identical Rutans which were both sent to different years in the past in damaged ships . ( PROSE : " Beast of Fang Rock " ) Rutan sent to 1902 . One of the Rutans arrived in 1902 . Unaware that it had travelled through time , the Rutan followed standard procedure for a damaged ship and set out to establish a base with a power source and to create a beacon to bring the Rutan Battlefleet to Fang Rock . ( PROSE : " Beast of Fang Rock " ) There it established the beacon and began to kill the lighthouse keepers and shipwreck survivors , one by one . Using recent Rutan technological developments , the Scout shape - shifted into the form of the lighthouse keeper Reuben Whormby . It electrocuted the others . After a short talk with the Fourth Doctor , the Rutan attempted to take the lighthouse . Leela destroyed it with a makeshift mortar and gloated over the scout as it lay dying . ( TV : " Horror of Fang Rock " ) Three regenerations later , the Doctor was forgiven by the Rutan Host for killing the scout . ( PROSE : " Shakedown " ) Rutan sent to 1822 . The other Rutan arrived at Fang Rock in 1822 , where it attempted to replace lighthouse keeper Jacob Travers . However , Travers ' DNA contained a morphic gene which was activated during the copying process and he was transformed into a werewolf . The Rutan fled and hid in a cave . Months later , the Rutan was found by Alfred Scott , who the Rutan copied and killed . The Rutan lived as Scott for some time , during which it grew an affinity for humanity . In 1823 , Travers returned to Fang Rock after a year in Bethlem Royal Hospital and attempted to kill the Rutan . The Rutan was saved by Anne Travers , who came to Fang Rock from 1969 using the Rutan ' s osmic projector . Jacob Travers died in the skirmish and the Rutan took his place . The Rutan realised that in order to preserve time it needed to stay close to the Travers family and make sure that Anne experimented with the projector in 1969 , causing it to be sent back in time in the first place . In 1829 , the Rutan stopped being Jacob Travers and took on the identity of " John Morecombe " . As Morecombe , the Rutan established " Morecombe & Slant Solicitors " to protect the financial future of Anne Travers ancestors . Sometime later , the Rutan took on the identity of " Rupert Slant " and continued working at " Morecombe & Slant " . On 2 May 1969 , Slant contacted Anne Travers and gave her the osmic projector . ( PROSE : " Beast of Fang Rock " ) In July of the same year , Anne visited Slant , now presenting as feminine and using the name Ruby , to gain information about the Ferae . ( PROSE : " Moon Blink " )
