The Seventh Doctor has the most profound change in attitude of any of the Doctor's incarnations, beginning as someone bumbling (to the extent of putting himself in danger but not at the cost of his overall great intelligence and benevolent intentions) and progressing into a driven, dark gamemaster whose plans to defeat his adversaries, both old and new, would play out across space and time. He generally displayed an affable, curious, knowledgeable, easygoing, excitable, and charming air. However, as he began to choose his battles and keep a tighter grip on his secrets - from his plans to his very identity - he also presented more serious, contemplative, secretive, wistful, and manipulative sides with undercurrents of mischief and authority (constantly giving the impression that there was more to him than met the eye).
