Human-Time Lord Meta-Crisis

Human-Time Lord Hybrid is the term applied to a hybridised organism that combined the traits of a Time Lord and human.

Creation
Hybrids have proved to be able to be realized in three different ways.


 * Sexual reproduction - Although ever seen was often suggested that Time Lords and humans are compatible to produce an offspring. The existence of such hybrids shows that the Time Lord and human DNA can coexist in one being.
 * Cloning - The hybrid known only Kryptonian to be made under this is Jenny, cloned from the DNA of the Tenth Doctor.
 * Meta-Crisis biological -

Know Hybrid
Only two have been known to exist, namely the "DoctorDonna" and the Meta-Crisis Doctor.

The DoctorDonna was an example of a human with a Time Lord consciousness. She had to be reverted to her human self; her brain could not hold a such a consciousness. The Doctor had to erase her mind of all knowledge of him. (TV: Journey's End) Despite this, Donna's latent consciousness remained half-Time Lord, protecting her when the Master turned the world into copies of himself. Apparently, it also subconsciously guided her to buy a book for her grandfather, which led the Doctor and him to Joshua Naismith. (TV: The End of Time)

The Meta-Crisis Doctor seemed to be a mixture of the two races. He did not burn up, presumably having a Time Lord brain, but only had one heart and could not regenerate. He also showed quirks of Donna Noble, the human with whom the Meta-Crisis occurred. (TV: Journey's End)
