Time Lord

The Time Lords are a sentient race of humanoids from the planet Gallifrey, so called because of their ability to manipulate time and space through technology more advanced than most other civilizations.

Though they appear human, Time Lords differ from humans in many respects. Their life span can be counted in centuries, and they can heal from injuries fairly quickly. They have the ability to regenerate should they be mortally wounded. They have two hearts, a respiratory bypass system, and an internal temperature of 15°C (59°F).

Time Lords can communicate telepathically, though often times this skill is boosted by their TARDIS, with which they share a symbiotic relationship. They can erase or block memories or information from an individual's mind through telepathic interaction. They also have a natural sensitivity to time, sensing the passage of time in a different fashion than humans, as well as being able to see most of time; that is, perceiving the past, present, and all possible futures simultaneously.

A Time Lord's most distinguishing trait is the ability to regenerate their bodies when their current body is mortally wounded. This process results in their body undergoing a transformation, gaining a new physical form and new personality, but the same memories. Time Lords have been shown to have varying levels of control over what their next incarnations will look like but the results are mostly random. A Time Lord can only regenerate twelve times before dying (thirteen incarnations in all.) After the Regeneration the Time Lord is in a state of mental instability, confusion, and stress as he or she adjusts to a new body.

The main character of the British science fiction series Doctor Who is a member of this race.
