10 Doctor Who Moments Peter Capaldi Can't Be Darker Than

3. The Tenth Doctor Becomes The Time Lord Victorious

Yes, that's three times he's appeared on this list. The Tenth Doctor definitely was a dark one. When the show was revived for 21st century audiences, it developed the character of the Doctor considerably, moving him on in his life, adding new backstory and also giving him extra subtext; namely recurring references to him being a god, or at least an all-powerful cosmic being. Oh, wait, that's still a god. This came to a head in David Tennant's penultimate episode in the role as, in a thematic sequel to Fires of Pompeii, the Tenth Doctor comes across another fixed point in time - the deaths of the crew of Bowie Base One on Mars. Why are fixed points never nice things? It wouldn't be so bad if the Doctor had to make sure a picnic had to happen. However, the Doctor decrees he is not about to stand by and do nothing and declares that because he is the last Time Lord he can do whatever he likes. To feed his own arrogance rather than to do the right thing, the Doctor breaks the laws of time and brings the crew back to Earth. It's a terrifying moment because - with a manic glint in his eye and talk of being an omnipotent 'Time Lord Victorious' - the Doctor becomes the exact opposite of what we love about him; a power-mad tyrant, undeterred by the effect his actions will have on the universe. In short, he becomes the Master. While some have said that Capaldi would have made a good Master instead of Doctor, we don't see him playing both characters at the same time.
