March of the Adipose

The March of the Adipose occurred in London.

The march
The Adipose pill was given to overweight humans by Matron Cofelia (under the alias Miss Foster). The Adipose were produced from a kilogram of fat from those who had been taking the Adipose diet pills. Matron Cofelia activated her signal to induce the birth of the Adipose babies.

They marched along the streets of London towards the ship, though a couple were accidentally hit by a taxi when it tried to skid to a halt. The machine producing them was deactivated by the Tenth Doctor using two Adipose Industries pendants, but ten thousand Adipose had already been born. The Adipose walked to Adipose Industries HQ, where Miss Foster was waiting. Soon after, the Adiposian nursery ship descended and used levitation beams to lift the Adipose to the ship.

Once the Adipose babies had been brought onto the nursery ship, the Adiposian First Family deactivated the levitation beam carrying Matron Cofelia to the ship. They had realised that, as an accomplice to their criminal actions (interfering in a primitive planet, banned by the Shadow Proclamation), she was a liability which had to be removed. Matron Cofelia fell to her death. They then left Earth. (TV: Partners in Crime)

Aftermath
Upon returning to Chiswick just prior to the Sontaran invasion of Earth, Donna thought of the Adipose amongst other recent experiences. (TV: The Sontaran Stratagem) Later, whilst looking into the disappearance of Earth among other planets at the Shadow Proclamation with the Doctor, Donna brought up Miss Foster's mention of the Adipose breeding planet being lost which, along with the disappearance of Pyrovillia, led the Doctor to realise that the current Planetary Relocation Incident involved the relocation of planets from time as well as space to the Medusa Cascade. (TV: The Stolen Earth) After defeating the New Dalek Empire, the Meta-Crisis Tenth Doctor saw that Adipose 3 and all the other planets were returned from the Cascade. (TV: Journey's End)

Following the incident, some on the internet suggested that it may have been a hoax, or a publicity stunt which backfired. Penny still worked for The Observer in 2022. She met Cleo Proctor in Soho, where she was interviewed about the Adipose Industries incident. Despite Penny's girlfriend saying that she had the memory of an elephant, she could remember remarkably few details about the Doctor himself. Cleo spoke about the odd situation with her friends, noting that it was like the Doctor had been redacted from her memory. (AUDIO: SOS)

Later, when Cleo attempted to contact Penny to request she waver her anonymity, her signal was cut off by a strange distortion. (AUDIO: Hysteria) Penny had disappeared shortly after meeting Cleo, (AUDIO: Interrogation) due to a psychic virus which had infected the Thirteenth Doctor and was erasing people who had had contact with her. The Doctor and Cleo eventually restored the disappeared. (AUDIO: Salvation)

Parallel world
In a parallel world, the March of the Adipose occurred in America instead of the UK, because Britain was closed off from the rest of the world following the destruction of London and irradiation of Southern England. Sixty million Americans were killed when they were fully converted into Adipose children. Prior to this, they were planning to send Britain £50 billion in financial aid, but it was cancelled due to the invasion's devastating effects. (TV: Turn Left)
