First Doctor/Non-valid sources

The First Doctor was depicted in several sources considered by this Wiki as "invalid sources".

Life on Gallifrey
Following the Doctor's theft of the TARDIS, the Gallifrey Gazette investigates his background, learning that he graduated in Music and Performing Arts from the Academy, even starring in an Academy performance of The Army Game, and to be currently going by the alias of "Doctor Wat Who" on Gallifrey; other aliases past and future of the Doctor are mentioned as "Doctor Spock, Mister Mann and Terry McNation". He is described as "a young man in his early centuries", with Susan Foreman stated to be 98-years-old. (PROSE: TARDIS Stolen!)

Life on Earth
After Ian Chesterton and Barbara Wright followed Susan home from school, (TV: An Unearthly Child) the Doctor peeked his head out of the TARDIS and watched as, nearby, Susan had mistaken a sentry box for the ship. (NOTVALID: Moments in Time)

Travels with Ian and Barbara
The Doctor was having a picnic on Vortis with Ian, Susan and Barbara, only for the classic "ants at the picnic" problem to rear its gigantic head in the form of the Zarbi. (COMIC: Untitled)

Meeting his future
The Doctor met his future selves on multiple occasions. He joined his next ten incarnations in giving a salute, (COMIC: Doctor Whoah! 433) and had a party with them. (COMIC: Doctor Whoah! 467)

Post-mortem
In death, the Doctor was, for unknown reasons, relegated to the group of so-called "not-really-the-Doctor" Doctors. The aristocratic Ninth Doctor was told to join him after being turned away from the Ex-Doctors club. (COMIC: Doctor Whoah! 376)
