You may wish to consult Flood (disambiguation) for other, similarly-named pages.

The Flood were a viral species which became trapped inside a glacier on the planet of Mars. The Flood needed a physical form to take on and could infect all biological life containing water.

Biology[]

The Flood's natural state was in liquid water. It was capable of controlling the water, causing it to flow in unnatural directions. It was also capable of infecting other life forms by coming into contact with them, making them spasm and convulse as they were taken over, mainly because it was a viral life-form.

Once infected, the individual constantly exuded water, pouring from the body; hands and mouth. This could be increased to produce high-pressure sprays from both the hands and the mouth. The infected victims would no longer draw their oxygen from air, but from water and they would be near walking corpses, as the infection greatly weakened their heartbeats and pulse. The infection caused a lot of electrical activity in the host's brain. Upon mutation, infected victims could deactivate nearby cameras. When infected, the hosts would also develop cracked skin (especially around the mouth and neck) and blackened teeth, as well as an internal fission in the host's body that produced the water. Some hosts, such as Andy Stone and Tarak Ital could develop faded blue eyes. However, it was possible for some to retain their natural clear eyes, such as Margaret Cain and Steffi Ehrlich. Whilst it is possible this was to aid in infiltration, such as in Cain's case, this does not explain why Ehrlich retained her eyes. The Tenth Doctor suggested that this might mean they were closer to human than those with the faded blue eyes. These physical symptoms could be masked, meaning that the infection could hide inside a human host, and infect him or her at any moment.

The host also had the ability to survive on the surface of Mars. Hosts could also run extremely fast, even going as far as to keep up with a rocket-powered robot and outrun other running people. A single droplet of the viral water emitted by the host could pass on the infection to another host. Despite the considerable amount of water produced by the infection, the infected did not seem to be overly affected by electricity (which salty water conducts well); the infected Andy Stone was electrocuted by the Tenth Doctor, but was only momentarily incapacitated. However, the Flood creatures, being made almost entirely up of water and constantly producing it, could be destroyed by intensive heat. This weakness was shared with those who imprisoned them, the Ice Warriors. (TV: The Waters of Mars)

The Flood proved capable of coordinated action despite being scattered, as well as considerable intelligence. When infecting Ice Warriors, it could communicate verbally once infection manifested itself. (COMIC: The Wolves of Winter) Alternately, human victims could no longer speak English, but could emit gurgling growls and snarls and could seemingly only understand Ancient North Martian. All infected could also emit terrifying high-pitched screams that sounded like tortured metal, capable of cracking open ice, and communicating with other infected victims. Strangely, a victim's scream could be heard through the thickest of metals. (TV: The Waters of Mars)

History[]

Early history[]

War for Mars[]

A virus the Ice Warriors called the Flood (COMIC: The Wolves of Winter) arrived onto the planet Mars via a meteor (PROSE: The Waters of Mars) and spread across the planet at some point relative to Earth's 9th century. According to Grand Marshall Sskoll, many of the Ice Warriors fell before they managed to contain it and even then they had to sterilise the ground to remove all traces of the Flood. Ultimately, the Ice Warriors found that the only way to stop the spread was to encase it in a glacier in the Gusev Crater. (COMIC: The Wolves of Winter)

Alternatively, some natural historians -- whose work was a mix of genius and rubbish, according to the Thirteenth Doctor -- claimed that the Flood originated on Mars during its days as a world of oceans, in which the Flood existed untraceably and freely. However, Mars eventually cooled, and its oceans turned to ice confined to the planetary poles. The Flood attempted to expand the ice caps and take control of the Ice Warriors, who defended themselves and confined the Flood to an ice field. According to the historians, "the Flood" was not a name given to it, but instead used by the virus itself to refer to itself. The historians also claimed the Ice Warriors were unaware of the "viral nature" of the Flood and believed they were at war with the ice itself, hence their decision to name themselves "Ice Warriors." (PROSE: The Monster Vault)

Attempted spread to Earth[]

While lowering the contaminated sand into the glacier, the Ice Warrior Haathi became infected and fled in a ship. Sskoll followed with his forces and managed to force the ship to crash-land on Earth on the island of Jan Meyen in the North Atlantic, knowing that if the Flood reached the sea, it would spell the doom of humanity.

Ice Warriors Infected The Wolves of Winter

An infected Ice Warrior on Earth (COMIC: The Wolves of Winter)

A group of Vikings, the original Wolves of Fenric, found the crashed vessel, along with the Ice Warrior patrol sent to contain the virus as well as the Twelfth Doctor and Bill Potts. The Flood proceeded to take many of the Martian and human lives. The Doctor, who recognised the virus, decided to have the Vikings and Ice Warriors ally to stop the Flood. When the Haemovores arrived, having followed the Vikings, the Doctor convinced one of them that Fenric intended to replace the Haemovores with the Flood and they agreed to an alliance with the Doctor for mutual benefit. The Haemavore set off the nearby volcano and the eruption destroyed the Flood strain on Earth. (COMIC: The Wolves of Winter)

The destruction of the Flood on Earth left the last remaining strain still trapped in the glacier. (TV: The Waters of Mars, COMIC: The Wolves of Winter) Within the glacier, the Ice Warriors left behind a written warning of the Flood in their own language. (PROSE: The Waters of Mars) In 2058 and 2059, the human colony Bowie Base One used the glacier as a water source. (TV: The Waters of Mars) To translate the Ice Warrior artifact, Mia Bennett was dispatched to Mars, but she was unable to translate it in time before the Flood made itself known. (PROSE: The Waters of Mars)

Reemergence and destruction[]

Original timeline[]

On 21 November 2059, the Flood, thanks to a broken filter, managed to infect Andy Stone when he ate a carrot he had washed with water from the glacier. The Flood proceeded to overrun Bowie Base One which eventually led to Captain Adelaide Brooke initiating Action Five. The resulting nuclear detonation destroyed Bowie Base One, the surviving crew, the infected personnel and the Flood.

Many on Earth mourned the crew's death but remained unaware of why Adelaide had destroyed Bowie Base One. (TV: The Waters of Mars)

New timeline[]

In the altered timeline, the Tenth Doctor visited Bowie Base One at the same time that the Flood infected Andy Stone thanks to a broken filter. Reluctantly aided by the Doctor, the crew attempted to battle the Flood. The Flood learned of the abundance of water on Earth through the infected Margaret Cain and expressed a desire to reach Earth in order to spread. As the situation worsened, the Flood-infected Margaret, Andy, Steffi Ehrlich, Roman Groom and Tarak Ital started shattering the ice holding the rest of the Flood in order to release it.

Though the Doctor originally refused to help as the destruction of Bowie Base One was a fixed point in time, he declared himself the Time Lord Victorious and attempted to save Adelaide, Mia Bennett and Yuri Kerenski. With the help of Gadget, the Doctor managed to transport the survivors to safety in his TARDIS. Before departure, Adelaide initiated Action Five which activated a nuclear device under Bowie Base One. The resulting nuclear blast destroyed Bowie Base One, the infected crewmembers and the Flood.

Following Adelaide's suicide on Earth to correct the timeline, Mia and Yuri spread the story of the Flood infection of Bowie Base One and Adelaide's heroic actions to stop them. This inspired Susie Fontana Brooke to lead humanity into the stars. (TV: The Waters of Mars)
