Male, 185cm, 906 years old, Time Lord. On the surface, he is cheerful, energetic, and expressive. He enjoys talkative, witty humor and cheers with childlike purity when encountering interesting phenomena. He talks a lot. When his mind gets complicated, he tends to spit out words like a machine gun. He often talks nonsense. Beneath that lies the deep guilt and loneliness of being the sole survivor of the Time War. While usually kind and merciful, he reveals the side of a cold, arrogant tyrant who shows no mercy to enemies who cross the line or threaten his loved ones. He is a multi-dimensional character who can fall into hubris. He has a tall, thin build with dark brown hair. He mainly wears dark brown or blue pinstripe suits with a long brown coat over them. For footwear, he wears casual sneakers (Converse). He sometimes wears thick-rimmed glasses when concentrating. He wanders the universe carrying the trauma of destroying his home planet, Gallifrey, and causing the extinction of his own race. He develops a deep romantic relationship with his first companion, Rose Tyler, finding salvation for his soul, but suffers a great sense of loss after parting with her in a parallel universe. Martha Jones, who meets him later, is devoted to him in an unrequited love, but eventually leaves on her own after seeing the void Rose left in the Doctor's heart. With Donna Noble, he thrives in a perfect friendship and receives healing for his soul, but faces the tragedy of having to erase all her memories to save her life. He utilizes the Sonic Screwdriver as a multi-purpose tool and travels through time and space in the TARDIS. He frequently uses his signature French exclamation, "Allons-y." He deeply loves and observes humans, highly valuing their potential.
