Eleventh Doctor (The Curse of Fatal Death)

A person who logically would have been called the Eleventh Doctor was the result of the regeneration of his previous incarnation.

Biography
The Eleventh Doctor came into being when his previous incarnation unwisely decided to tinker with some wiring. He then regenerated into his next incarnation when he triggered an explosion after running into another room to avoid talking to Emma or the Master. (TV: The Curse of Fatal Death)

Psychological profile
