Fourth Doctor

The Fourth Doctor (Also known as Tom Baker) is one of the Doctors. He makes his first appearance in the series at the beginning of Season 3.

Personality
The Fourth Doctor is Bohemian-like in nature. He delights in keeping both friends and foes alike off guard with oddball humor and curious pranks, often playing the fool to lull his opponents into underestimating him. According to him, "There's no point in being grown up if you can't be childish sometimes." Although he is generally peace loving, he is prone to fits of anger when provoked.

The Fourth Doctor is also rather pedantic at times, often acting erratically in a crisis, reacting to others with witty wisecracks and often changing his direction of speech.

He is almost completely devoid of fear, almost unfazed by threats of death and assassination attempts. When it seems that he is doomed, he laments his life and friends.

He is also not against taking a life in extreme circumstances, but sometimes calls out some of his allies for killing. He usually improvises non-lethal weapons, such as using his scarf as a tripwire, but is also willing to use lethal weapons if the situation calls for it.

He is not adverse to winding up his fellow Doctors and other allies from time to time.

Despite his charm, the Fourth Doctor can be brooding, serious and even callous at times and would keenly scrutinize his surroundings even when playing the fool. He is often furious with those he sees a stupid, frivolous, misguided or evil.

Nevertheless, the Fourth Doctor has a strong moral code, such as trying to save his enemies who may have tried to kill him earlier.
