Biography
In the wilderness, I.M. Foreman found 12 individuals all of whom had no memory of who they were. Together they formed I.M. Foreman's One-Species Nongenetically Engineered Travelling Show, a show which was actually a complex space time event that could travel in time. As a priest, he had been given the gift of regeneration, but in those days it was much less stable than modern regeneration, meaning he tended to absorb the DNA of whatever he encountered.

He eventually arrived on Dust where his true nature was revealed to the Third Doctor and Sarah Jane Smith. I.M. Foreman's travelling show was made up of thirteen acts, which were all aspects/bodies of I.M. Foreman, one for each regeneration. When the Remote attacked the planet, they let out Number 13, the most unstable of all his regenerations, which tried to eat everything and absorb it into its own structure. Eventually it blended with the planet Dust to turn it into a new, vital world, Foreman's consciousness forming a bond with a woman called Magdalena to allow him/her/it to experience the world as its residents would.

The other regeneration aspects were sent back through time, their travelling show exploding as it ended up back in the Dark Times just before the first I.M. Foreman found the show, triggering a regeneration for all twelve aspects.

From at least the early 1960s to at least the mid-1980s, there was an I.M. Foreman junkyard located at 76 Totter's Lane in London. It was here that the First Doctor parked his TARDIS for several months in 1963 as he worked on securing the Hand of Omega; (TV: Remembrance of the Daleks) his granddaughter adopted the name Susan Foreman from the location. (TV: An Unearthly Child) This junkyard was eventually revealed to be a shape that the show had taken shortly before the Doctor's arrival on Earth, the show "shedding" its old appearance after leaving its previous location; the Third Doctor later guessed that the show's presence had drawn his TARDIS to that location when he landed on Earth.
