The Tenth Doctor inherited the sense of loss the Ninth Doctor carried with him, and from time to time it troubled him. But his regeneration gave him a degree of remove from the Time War and he was able to have a little more fun. He was also able to consolidate his relationship with Rose, although he still found it impossible to say out loud that he loved her. He was, like all his predecessors, a Doctor with a strong sense of justice, with mercy for the innocent, but a metaphorical sword for the guilty. His best 'superhero superpower' is his ability to instill trust in those around him, even those initially hostile to him.
