The Eleventh Doctor

In a universe other than the one that the renegade Time Lord known as the Doctor called home, a person who logically would have been called the Eleventh Doctor was the result of the regeneration of that universe's Tenth Doctor.

This incarnation came into being when his previous incarnation unwisely decided to tinker with some wiring.

Because women terrified him, this incarnation found Emma very intimidating. He even appeared shy when talking to the Master because of his "breasts", which were really Dalek etheric beam locators.

He regenerated into his next incarnation when he triggered an explosion after running into another room to avoid talking to Emma or the Master.
