has gloss | eng: Regeneration, in the context of the long-running British science fiction television series Doctor Who, is a biological ability exhibited by the Time Lords, a race of fictional humanoids originating on the planet Gallifrey. This process allows a Time Lord who is old or mortally wounded to undergo a transformation into a new physical form and a somewhat different personality. The process has been used ten times to introduce a new actor for the role of the main character of the programme, the Doctor. |
