Tenth PhDoctor

Tenth PhDoctor is the tenth incarnation of the Alpha-Omegatrix's DNA sample of a Time Lord, also known as a Gallifreyan, from Gallifrey.

Personality
Unlike his immediate predecessor, who was plagued by melancholy due to his actions during the War, this incarnation was outgoing, lively and genial, a demeanour that hid the "survivor's guilt" that had plagued him since the war. Late in his life, however, the weight became much more pronounced. If prodded too much, he would erupt in an almost righteous sense of fury.

Death
Maklar was trapped inside a radiation control booth which was about to be flooded with radiation. Despite his own anger about the terrible things the universe rewarded him with and Maklar's pleas to leave him, he released Maklar and took his place, receiving a fatal level of radiation. PhDoctor's regenerative process had started. Unlike previous occasions, however, the actual regeneration did not immediately occur, and PhDoctor was able to not only return Maklar home, but spend an unknown length of time travelling through time and space revisiting his past companions, an act he referred to as his "reward".

Reaching the TARDIS, he piloted it into orbit around Earth, and stated, "I don't want to go." Taking a deep breath, PhDoctor closed his eyes and regenerated into his eleventh incarnation. This time the energy released during the regeneration was enough to cause massive damage to the TARDIS.

Appearance
He looks like Matt from the second series, but with red aspects in his outfit. The outfit is the same worn by the Fifth PhDoctor, but changed slightly. The black overshirt is slightly torn at the sleeves and collar, and the undershit has darker red stripes, and tears where the gloves were torn off. In Time Crash, the Fifth PhDoctor reveals he had intended to give the undershirt stripes and remove the gloves.

Powers
As a Time Lord, he has many powers. A binary vascular system, immunity to the vacuum of space, increased sound resilience, healing coma, radiation absorption, high electrocution immunity, telepathy, and regeneration up to 3 times, having 13 incarnations in all.

The Alpha-Omegatrix gives him what most Time Lords have, a sonic screwdriver, a psychic paper, and a TARDIS, Time And Relative Dimension In Space. This gives him a few controls over things, ebducing someone into seeing what he wants, and time-space travel.

Weaknesses
He has fatal reactions to one of his hearts not working.

Although he can regenerate 3 times, after his 13th incarnation, Richard does not have access to him.
