We hardly get a chance to know the Eighth Doctor in his one true story. (I am told that his character really comes to life in later audio stories that were put out, but I pretty much only know him from the TV movie and his brief webclip reprisal prior to his regeneration.) Though he is in a post-generation haze for the start of the story, the Doctor suddenly comes alive in the middle once he remembers who he is and we start to see his personality—excitable and happy, sophisticated in appearance but quick to joke with a twinkle in his eye. There is not much hard edge in his early appearance, even when facing down the Master, but by the end of his regeneration when we see him again he is haggard and wearied and his initial good humor is extinguished by the obvious anguish of experiencing the deaths of many others in the Time War.
Signature story: Doctor Who (The Movie)
Best match to a companion: Lucie in the Big Finish audios (so I have read)
Charley, C’rizz, Lucie, Tamsin, Molly, friends, companions I’ve known, I salute you. And Cass, I apologise. Physician, heal thyself.
