Twelfth Doctor

The Twelfth Doctor (also known as Peter Capaldi) is one of the Doctors. He makes his first appearance in the sixth episode of Season 5.

Personality
A cynical man, the Twelfth Doctor adopts a less caring attitude and a more hostile nature, though he believes he gives people the benefit of the doubt. He is perfectly comfortable with placing his companions in danger if it means appeasing his curiosity, often leaving them out of the details in his plan or using them to distract attention from himself. However, if he believes that the danger is too great, he would either recruit necessary assistance or send his allies to the safety of the TARDIS.

The Twelfth Doctor prefers the moment where "everything is huge, everything is important, every detail, every moment, every life clung to the moment".

He usually finds it best to keep an open mind, unclouded by the opinions of others. He also favors the direct approach when encountering an obstacle. From the Eighth Season onwards, he starts using cue cards to help him socialize.

He also shows a strong compassionate streak, often running into danger to save someone. He tries to avoid harming those who are not in control of their actions, as well as defend them from their captors or those who would cause them further harm.
