Seventh Doctor

Regeneration - Post-Regeneration
It has been suggested (mostly through journeys through the Doctor's psyche) that his sixth self forced a regeneration in his seventh persona because he was too out of control, and was heading down the road to become the Valeyard. (NA: Timewyrm: Revelation)

Thus when the TARDIS was attacked by the Rani, the Doctor deliberately hit his head on the console, triggering a regeneration and allowing his seventh persona to come into being. Following his regeneration he had a slightly comic personality, due mostly to post-regenerative trauma. (DW: Time and the Rani)

Ace and Facing Fears
When the Doctor and Mel arrived on the planet Svartos the Doctor encountered Ace, a much more brash human and recognised something in her that would assist him in the future as Time's Champion. He used a mild form of hypnosis to persuade his current companion Melanie Bush into leaving him. (NA: Damaged Goods)

The Doctor lead Ace to through many challenges, leading her to face her fears, with the intent that she might take his place in the future.

Time's Champion
The Doctor became the eternal Champion of Time, assisting the universe and Time in the more complicated historical challenges. One such challenge involving the Hoothi was seen by Ace as an ultimate betrayal, leading her to leave his company during events on the planet Heaven. It also led Bernice Summerfield to join him. (NA: Love and War)

Death
The Seventh Doctor apparently "died" twice. The first death occurred at some point during his travels with Ace, although it is possible this occurred in an alternate universe/timeline (Death Comes to Time). Later, the Doctor was assigned to transport the remains of The Master from Skaro to Gallifrey, but due to interference from the Master the TARDIS arrived in late 1999 San Francisco. The Doctor walked into a gangland gunbattle and was shot twice. Although rendered unconscious and taken to hospital, it is determined that the bullets caused only minor injury. However when an X-ray reveals an abnormality (the apparent appearance of a second heart), specialist Dr. Grace Holloway undertakes exploratory surgery. Unfamiliar with Time Lord physiology, and not heeding the Doctor's warning, Holloway damages the Doctor's circulatory system with her probe, causing him to die on the operating table. Unlike previous regenerations, however, the change this time did not occur for several hours, a delay the Eighth Doctor later attributed to his being under anesthesia at the time of his "death". (''Doctor Who: The TV Movie)

Characteristics
The Seventh Doctor was a darker character, manipulative and frequently saw the 'bigger picture' rather than the world before him.

Personality
"to be added"

Habits and Quirks
The Seventh Doctor played a lot of chess, and not just on a chess board. He used it to battle his enemies and also to move his companions and his adventures around in the universe. (DW: The Curse of Fenric) He's also famous for his "rolling r's".

One of the Seventh Doctor's early habits was his tendency to spout mangled cliches such as "Time and tide waits for the snowman". This quickly vanished as he adopted a darker persona.

Mysteries and Discrepancies

 * The Doctor made a slip of the tongue when discussing the Hand of Omega with Ace in 1963, stating that 'we' had trouble with the prototype, rather than 'they' being early Time Lords. He may have been referring 'we' as a species not 'we' as a group.
 * Lady Peinforte claimed knowledge of the Doctor's actions during the 'Dark Times' of early Gallifrey, well before his assumed birth date, gathered from the Silver Nemesis statue.
 * The Doctor once stated to Davros that he was 'far more than just another Time Lord'.
