First Doctor (The Daft Dimension)

A version of the First Doctor existed in the Daft Dimension.

With companions
When the Doctor was being served a meal on Skaro with his granddaughter Susan, and Ian and Barbara, the group ambushed their waiter, Dave the Dalek, and shoved mud in his eye before they escaped. (COMIC: The Daft Dimension 553)

The Doctor was with Susan on Skaro when she complained about the rubbish radio reception. (COMIC: The Daft Dimension 509)

He left Susan, rather abruptly, on Earth to start a new life with David Campbell, something which Susan did not entirely appreciate. (COMIC: The Daft Dimension 552)

Multi-Doctor encounters
He celebrated Christmas aboard his TARDIS with his other incarnations on at least two occasions. (COMIC: The Daft Dimension 507, The Daft Dimension 559)

On another occasion, he was captured and imprisoned within the maximum security facility by the Judoon, alongside his future incarnations. (COMIC: The Daft Dimension 550)

Final exploits
When the Twelfth Doctor began to regenerate in Antarctica, the First Doctor appeared to roast marshmallows on his regeneration energy. (COMIC: The Daft Dimension 515)

When exploring Villengard with the Twelfth Doctor, he bailed on his successor to return to the I.M. Foreman scrapyard to sell off some discarded Dalek sucker arms as plungers. (COMIC: The Daft Dimension 524)
