Sixth Doctor

The Sixth Doctor (also known as Colin Baker) is one of the Doctors, making his first appearance after being reawakened from suspended animation in the fourth episode of Season 8.

Personality
The Sixth Doctor is known to be unpredictable, constantly self-absorbed, stubborn, argumentative, moody, melodramatic and arrogant, much to the annoyance of his fellow Doctors. However, he is critical of himself in some situations and, beneath his thunderous exterior, he is a passionate and empathic person.

He believes himself to be blessed with both "tact and finesse" and believes that he could subdue his opponents with his charm.

The Sixth Doctor does not suffer fools gladly, and sometimes endures the presence of others more than he enjoys it. However, he enjoys the company of his allies.

Despite his often unstable demeanor, the Sixth Doctor is quick to act when the situation calls for it, and very little, even his fellow Doctors, get in his way. Occasionally, he has found himself in situations where he decides that he is doomed and accepts his fate. He is also sometimes literal-minded.

He also seems unable to see his own faults, but would hypocritically criticize those that showed them. In Season 9, when Skaldak refuses to drop out of a window because it's too high, the Sixth Doctor replies by saying "Don't be such a baby!" and kicks him out of the window. However, after Skaldak's death in the Season 10 finale, the Sixth Doctor admits that he may have misjudged Skaldak.
