Eleventh Doctor (Ganger)

The Doctor was a Ganger clone created from the Flesh in the image of the Time Lord known as the Doctor.

Biography
When a bolt of solar energy struck the vat the Flesh was held in, it formed a copy of the Eleventh Doctor from a tiny measure of his genetic material, gained when he touched the Flesh. He tried to make contact with Jennifer Lucas, but scared her away as he had not yet stablised his form. When the humans and the real Doctor fled from the other Gangers into the chapel, this Ganger confronted them and told them to trust him. (DW: The Rebel Flesh)

At first, the Ganger had some trouble adapting to the Doctor's DNA due to the residual traces of his previous incarnations in his body. These caused him to briefly act like his first, third, fourth, and tenth incarnations, which he, like the real Doctor, did not like. He stabilised into a form and manner virtually identical to the Eleventh Doctor's; the only way to distinguish them was their difference in shoes, as the original Doctor had replaced his after the initial scan. The two Doctors subsequently swapped shoes while their companions were distracted in order to prove that Gangers were no different from their originals.

The Ganger Doctor sacrificed himself and Ganger Miranda to stop Ganger Jennifer, setting the sonic screwdriver to a frequency that would cause the Flesh to collapse, in full knowledge that this would destroy him too, so that the others would be encouraged to negotiate better conditions for the Gangers. (DW: The Almost People)

Personality
He and the original Doctor acted just like natural twin brothers would: completing each other's sentences and knowing what the other was thinking before they said it.

Like his original, Ganger Doctor disliked viewing his past lives and wished to be done with fast-forwarding through them. After imitating the First, Third, and Fourth Doctors, he seemed particularly distraught after imitaing the Tenth Doctor.

Despite being a Ganger connected to the Flesh, which wanted revenge on humans for killing so many of its "children", Ganger Doctor shared his original's belief that Gangers and humans could peacefully co-exist.
