The Therapist

"The Therapist" was the primary alias of the renegade Time Lord from Gallifrey who travelled through time and space with various companions in his stolen TARDIS. He was one of the universe's greatest defenders alongside the Doctor, having saved the cosmos thousands of times throughout his long life, becoming a hero across the universe.

Childhood
The Therapist was born on Gallifrey and a few hundred years younger than the Doctor. Although the Doctor served as a mentor figure for him, the Therapist was one in a few to know the Doctor's true name. the Therapist attended the Academy at age eight and was also a close friend of a Time Lord later-to-be known as The Mentor and the Therapist's arch nemesis.

Exile
When the Therapist was 536, he was framed by The Mentor and was sentenced to be executed. Although with his comedic wit, the Therapist told a joke to the guards and made them laugh, he then knocked them both out and escaped in a TARDIS, and decided to travel the universe and clear his name in a self imposed exile.
