Second Doctor (The Daft Dimension)

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

Post-regeneration
The Doctor regenerated from his predecessor whilst he was travelling with Ben Jackson and Polly Wright. He immediately faced problems with his new body, primarily that his ring and trousers no longer fit him. He later decided to do away with his stovepipe hat when it was knocked off of his head as he exited the TARDIS. He later decided to join The Beatles as their recorder player. (COMIC: )

Adventures
He celebrated Christmas aboard the TARDIS alongside his other incarnations on at least two occasions; the first was via a gathering of his predecessor and successors up to and including the Twelfth Doctor. (COMIC: )

The second such instance was when he was among the incarnations invited to Christmas dinner by the Thirteenth Doctor. During the occasion, the First Doctor gifted him with his recorder. (COMIC: ) He went on to play this recorder at the base of the what became the Singing Towers of Darillium, leading many, including the Twelfth Doctor and River Song during their last night together, to theorise the origin of the sound. (COMIC: )

He went to a funfair with his aunt, who he affectionately called his "giddy aunt" when she got dizzy on the waltzer. (COMIC: )

He was apprehended and imprisoned in the Judoon prison alongside his other incarnations. The Thirteenth Doctor frustratingly realised this fact immediately following her own incarceration, when she attempted to send out a psychic message to her other selves requesting their help. (COMIC: )

He joined his other selves in responding to a premature summons, again by the Thirteenth Doctor, to celebrate sixty years of their adventures. (COMIC: )

While his older & younger self's were celebrating their birthday, he spotted The Daleks stealing their cake. (COMIC: The Daft Dimension 597)
