Toclafane invasion

The Toclafane invasion would have occured in the early 21st century on Earth, but due to the actions of the Tenth Doctor, Martha Jones and Jack Harkness, the invasion never took place. (see The Year that Never Happened)

Origins
The Origins of the Toclafane Invasion started when the Tenth Doctor and Martha Jones refueling the Tardis using energy from the Cardiff rift. Jack Harkness spotted the TARDIS and jumped on it sending it to the year 100,000,000,000,000. There the last ever humans were preparing to board a ship that would take them to Utopia. Martha, the Doctor and Jack went to a base where the ship was being built. They met Yana and Chantho who where going to stay behind because they could only activate the ship from the ground.

The last humans boarded the ship and guards for the project brought the TARDIS back to the base, but the rocket needed to lift off. Jack Harkness went into a room and lifted canisters that helped let the ship go into space. Martha was talking to Yana and Chantho about the Doctor. While they were listening about Jack and The Doctor, Yana started to hear drumming.

It later appeared that Yana opened a watch and it was revealed to be a Chameleon Arc. He then discovered that he was the Master. Martha told the Doctor and Jack but it was too late, as Yana had killed Chantho and stolen the TARDIS. The Doctor reached the room and locked it to the last place where the TARDIS went which was Cardiff 2007. The Futurekind broke into the base and started to reach the room where the trio were. Luckily Jack, Martha and the Doctor used a Vortex Manipulator and reached 21st century Earth. (DW: Utopia / The Sound of Drums)

The Election
The Master on the day where the Trio arrived was elected Prime Minister of the United Kingdom under the name of Harold Saxon. He had married and ran for Prime Minister since the Downfall of Harriet Jones. Martha contacted her family to make sure they were safe. Martha's parents were being watched by an agent hired by "Saxon" called Miss Dexter.

Martha discovered that her TV had a bomb on the back of it and it detonated. Martha, Jack and the Doctor all ran out and they drove to her mother's house. She phoned her sister on the way but she was taken by Government Agents and her brother was told to take his family and go into hiding. Clive and Francine were later arrested.

The Doctor, Martha and Jack later found a way onto the Valiant and found out that at 8.02am the Toclafane were going to invade. They witnessed President Winters get killed by a Toclafane and the Doctor get hit by the Master's laser screwdriver. The Doctor aged 900 years in human form. And Jack kept getting killed repeatedly.

Martha then teleported to Earth using Jack's vortex manipulator and witnessed millions of Toclafane wreck havoc. (DW: The Sound of Drums)

The Year That Never Was
Martha Jones spent the year in between May 2008 and May 2009 traveling the world. Alien races and invaders did not go to the planet due to the fact that the human slaves where building missiles that would destroy them. On aboard the Valiant, Francine and Clive Jones were slaves of the Master as well as their daughter Tish. Jack Harkness was chained up in the engine room, and as for the Doctor he remained on the ship living inside a tent and forced to watch whatever the Master did.

Martha met with Tom Miligan, a doctor who was seeking to repel the Toclafane, and they travelled to Professor Allison Docerty's lab and figured out a way to take a Toclafane hostage in order to discover the species' true identity. Upon capturing a Toclafane and opening up its armoured shell, they discovered that the Toclafane where the humans from the year One Hundred Trillion and the Toclafane that Martha captured had the memories of Creet, a young boy from planet Malcassairo whom Martha had met and liked. The Toclafane said that the legends had lied to them; that there were no diamond-skies in Utopia, only "darkness, the never-ending darkness" and then out of despair the humans cannibalized themselves, and integrated themselves into armoured shells, becoming the Toclafane, and travelled with the Master to a void between dimensions, where they would ultimately invade Earth in 2008. When Tom Milligan asked why the Toclafane were slaughtering humanity, as humans and Toclafane were one and the same, the Toclafane sniggered and said "Cos it's fun." Tom, horrified, shot the Toclafane.

The next morning, the Master was going to launch the entire Toclafane fleet towards the Universe itself, as he had plans to rule the entire Universe and create a new Empire. Martha travelled to London to stop him, but she was caught by the Master, who had been aware of her presence. Thus she was taken to the Valiant once again and made to watch as the Master prepared to commence his war. He revelled in his apparent victory, until Martha revealed her plan that when humanity thought the word "Doctor" the power would make the Doctor whole again. This occurred and Jack led the guards to the TARDIS just as the Toclafane were about to leave Earth to invade the cosmos. Jack Harkness destroyed the Toclafane guarding the TARDIS and destroyed the paradox machine successfully, and thus the Toclafane vanished from the skies of Earth and were teleported back to Malcassairo and thus they never invaded.
