Adolf Hitler/Other realities

Timewyrm: Exodus
In an alternative timeline in which Hitler did not lose the power of the Timewyrm, Germany conquered the United Kingdom and the rest of Europe. Hitler's strategy for the conquest of the rest of the world continued to be influenced by the Black Coven. For Hitler, since he had never learned how to control the Timewyrm, he was still afflicted by its power. He suffered fits of rage which became even more intense over time, much to the concern of Martin Bormann. The Seventh Doctor and Ace, after visiting the occupied London of this timeline in May 1951, prevented it from coming to pass. (PROSE: Timewyrm: Exodus)

Johann Schmidt's timeline
In a different alternative timeline in which Nazi Germany won World War II and eventually conquered Africa as a result of the Seventh Doctor and Ace accidentally leaving laser technology in Colditz Castle in October 1944, the Mau Mau Uprising against Nazi rule took place in Kenya in 1953, with Hitler sending in the Luftwaffe immediately. On Hitler's orders, they proceeded to carpet-bomb the tribal areas and wipe out most of the native population. Within three years, a virulent plague had broken out in Kenya which killed many German soldiers. In 1957, Hitler placed Elizabeth Klein in command of a team of medical doctors and scientists who attempted to discover the cause of the plague. However, they were unable to do so. (AUDIO: A Thousand Tiny Wings) In 1961, Hitler died at the age of 71 or 72, having stockpiled a large number of alien artefacts, including the Doctor's TARDIS. He kept them a secret because he had feared the implications of intelligence superior to humans. The Seventh and Eighth Doctors averted this timeline. (AUDIO: Klein's Story)

Klein later told the Doctor that Hans de Flores was "always the Führer's favourite." She hoped that he would succeed Hitler as the Führer when the Fourth Reich was established. (AUDIO: A Thousand Tiny Wings)

Inferno universe
In one parallel world later ravaged by the Inferno Project, Adolf Hitler's Germany never rose to prominence. Europe had already been divided by the fascist Republic of Great Britain and Joseph Stalin's White Russia agreed to split Europe between each other. Their combined pressure forced Hitler to back down. (PROSE: The Face of the Enemy) Hitler was assassinated during a military coup in 1938. (PROSE: I, Alastair)

Pete's World
Hitler also existed in Pete's World, where he was cited as an inspiration by John Lumic alongside Genghis Khan and Machiavelli as people who "got what they wanted in spite of the little people". (PROSE: Lumic)

Warlords of Utopia
When many different Germanias unified to form the Greater German Reich, it was governed by the Council of Hitlers, representing every Hitler from a world that willingly joined. When the Empire of Empires, the Roman equivalent, went to war against the Greater German Reich, many Hitlers were killed during years of fighting. By 1964, as those remaining grew older, with some already having died of old age, they named August Hitler as their successor upon the death of the last Adolf Hitler. Shortly after, the rest of the Council were assassinated in a hydrogen cyanide gas attack orchestrated by August. (PROSE: Warlords of Utopia)

Germania I
The Adolf Hitler of Germania I, the Terra Optimus, achieved the greatest success. On 30 April 1945, having achieved overwhelming victory in World War II, he and his wife Eva Braun gave birth to a son, August Hitler. (PROSE: Warlords of Utopia)

Germania LXVIII
The Adolf Hitler of Germania LXVIII was a communist, who came to power during the Spartacist uprisings in 1919. He subscribed to the ideology of International Socialism. (PROSE: Warlords of Utopia)

Germania βα15
The Adolf Hitler of the Germania codenamed beta alpha one five was murdered by Ernst Rohm circa 1933, who took his place as Führer. (PROSE: Warlords of Utopia)

Prologue to Warlords of Utopia
In another universe, Hitler never became more than an anonymous artist. (PROSE: Prologue to Warlords of Utopia)
