The Eighth Doctor of Gaia

(Wow I just realized I never did Paul so here he is, the Eighth Doctor.)

The Eighth Doctor is a fictional character, the eighth incarnation of the Doctor seen on screen in the long-running BBC television science-fiction series Doctor Who. He was portrayed by Paul McGann. Though he appeared in only one TV feature, his adventures are extensively portrayed in other media.

Within the series' narrative, the Doctor is a centuries-old alien, a Time Lord from the planet Gallifrey, who travels in time in his TARDIS, frequently with companions. When the Doctor is critically injured, he can regenerate his body but in doing so gains a new physical appearance and with it, a distinct new personality. McGann portrays the eighth such incarnation, a passionate, enthusiastic and eccentric character. His only companion in the television movie is Grace (Daphne Ashbrook), a medical doctor whose surgery is responsible for triggering his regeneration. In the continued adventures of the character depicted in audio dramas, novels and comic books he travels alongside numerous other companions, including self styled "Edwardian Adventuress" Charley, the alien Destrii and present-day humans Lucie and Sam. In the revived Doctor Who TV series (2005-), it is implied that the Eighth Doctor was the incarnation to lead the Time Lords in a mutually destructive Time War with the Daleks.
