Four Doctors backup
Three alternate timelines came into being after the Tenth, Eleventh and Twelfth Doctors all touched a continuity bomb. Each then saw three possible versions of reality created by each of them making a single change in their lives. (COMIC: Four Doctors)

Time Lord victorious
For the Tenth Doctor, a reality was created where he never saved Wilfred Mott from radiation poisoning by sacrificing himself. (TV: The End of Time) Instead, he went on to conquer the universe and rule over it as the "Time Lord Victorious", succumbing to his dark side entirely. After a reign of great peace, he was killed by a Raxacoricofallapatorian, the result of which prevented his regeneration, stopping the Doctor from becoming the Eleventh Doctor. The original Tenth Doctor was distraught at learning his alternate self left Wilfred to die despite the Eleventh Doctor trying to comfort him. (COMIC: Four Doctors)

All of history at once
For the Eleventh Doctor, a timeline was envisioned where, instead of him and River Song touching to end the history where all of reality happened at once because they prevented a fixed point in time, (TV: The Wedding of River Song) they instead lived peacefully as a married couple. As the original Eleventh Doctor noted, this reality was dying because of such, appalled his alternate self would create such decay in the world. (COMIC: Four Doctors)

Allying with the Voord
In the Twelfth Doctor's case, his alternate self no longer travelled with Clara Oswald, having told her to "go to hell". (TV: Dark Water) Instead, the Twelfth Doctor travelled alone in his aging TARDIS. Given it seemed the safest version of history, the three Doctors agreed to enter the alternate Twelfth Doctor's timeline. Upon doing so, the Twelfth Doctor took them to meet the Voord, revealing he had allied himself with them to conquer the universe. Despite the three Doctors' efforts, the Twelfth Doctor succeeded in defeating them, sending his original self back in time to ensure his reality would come to be. (COMIC: Four Doctors)

Journey backup
In one version of history, The Doctor's TARDIS was caught in a magnetic hobble-field from a space salvage ship, operated by the Van Baalen Bros. The TARDIS was successfully captured by the Van Baalen Bros., causing the TARDIS to leak the past and future. As such, several alternate timelines were created. (TV: Journey to the Centre of the TARDIS)

Original timeline
While teaching Clara Oswald how to fly the TARDIS, the Eleventh Doctor lowered the TARDIS' shields, putting it into basic mode. Because of such, it was detectable to the Van Baalen Bro, who attempted to salvage it with a magno grab. The result of such severely damaged to TARDIS, causing an explosion. To save the Doctor and Clara, the TARDIS "wrapped her hands" around the heart of the blast, temporarily freezing it.

In the confusion, the Doctor made it out of the TARDIS, while Clara was lost inside. The Doctor soon met the Van Baalen brothers, who were unable to enter the TARDIS, taking the remote control for the magno-grab out of Gregor's pocket. He then cunningly lured them into the TARDIS, promising "the salvage of a lifetime". However, the Doctor forced the brothers, Gregor, Bram and Tricky, to help him find Clara by putting the TARDIS in lock-down and setting a non-existent self-destruct program, revealing the salavage he meant was not the ship but Clara.

Eventually, they found Clara in another echo room, the Doctor pulled her to safety and revealed the apparent self-destruct program had been a ruse, but found the engines had become unstable due to time leakage triggered by the incident, requiring a trip to the engine room to fix the problem.

While travelling through the Eye of Harmony, the quartet were trapped inside. They soon were burnt by the eye, transforming into molten time zombies. (TV: Journey to the Centre of the TARDIS)

Using the magno grab
In the next version of history, the time zombies the group had become leaked out into thew past because of the TARDIS malfunctioning. This time, Gregor told Bram to dismantle the TARDIS console despite his protests. While doing so, his time zombie from the original timeline killed him. Clara was also chased around the TARDIS by her time zombie, incidentally finding a book about the history of the Last Great Time War, reading an extract from it, revealing the Doctor's name.

Upon retrieving Clara in this timeline and making their way to the Eye of Harmony, having been chased by the time zombies, the Doctor revealed the zombies were echoes of himself and the others, burnt by the Eye. Gregor and Tricky ended up turning into them, and the Doctor and Clara were forced to run away from them, ending up in a chasm. Believing they were going to die, the Doctor admitted that he knew her two previous incarnations and demanded to know what she really was. Clara didn't understand anything, leading the Doctor to deduce to himself there couldn't be a connection.



Realising the chasm wasn't really a chasm, but the TARDIS "snarling", the duo jumped from the chasm, ending up in the engine room. Finding it frozen, the Doctor eventually realised they had to use the magno grab to change time. They returned to the main control room, where Clara revealed she knew the Doctor's name. The Doctor used his sonic screwdriver to melt the words "BIG FRIENDLY BUTTON" onto the device, in the hope his past self would read them and use the button to stop the salvage. The Doctor then tossed the magno grab into the past through a leak in the room.

Burning Clara's hand
In the third alternate timeline, the events played out as they did in the second, except Clara picked up the magno grab, burning the words "BIG FRIENDLY BUTTON" onto her hand. Eventually, the Doctor discovered the burnt imprint in the engine room, realizing he would have to take the magno grab back to the point of the disaster and activate the magno-grab remote himself, which had caused the burn marks on Clara's hand before, to stop the field and prevent the disaster. After he promised Clara that she wouldn't remember any of the events that had happened, the Doctor passed through a time rift to give the device to his past self. After instructing his past self to use the device, the future Doctor disappeared back through the rift.

Negation
Now having the magno grab, the younger Doctor pressed the button, which caused the TARDIS to disappear, escaping the Van Baalens and preventing its engine failure. (TV: Journey to the Centre of the TARDIS) The Doctor later displayed knowledge of all the alternate timelines. (TV: The Name of the Doctor)

Father backup
In an alternate timeline, Peter Tyler never died in a car crash. Instead, his daughter, Rose Tyler, used the Ninth Doctor's TARDIS to save back in time and save his life. (TV: Father's Day)

Witnessing the event
Initially, Rose asked the Doctor to take her back to the day that Pete died, 7 November 1987, so she could be there with him, given no one was until the ambulance arrived, by which time he had already died. The Ninth Doctor agreed. The pair witnessed as Pete exited his car and was run over by a young driver, who quickly sped away in panic. However, Rose was distraught at witnessing the event, running away, unable to will herself to be with him. She confessed her regret to the Ninth Doctor, desiring to try again. (TV: Father's Day)

Interferring
Reluctantly, the Doctor took her back one more. They waited out of sight from their past selves, who were still witnessing the event. The Doctor informed Rose they could not risk another return and must wait for their past selves to run off before Rose could intervene. However, Rose impulsively ran out, in front of her past self and saved her father's life, pushing him out of the way. The effect of such a change caused the Doctor and Rose's past selves to disappear.

Rose and the Doctor then accompanied Pete into his house. Once alone, the Doctor chided Rose for her actions, remarknig her change to time would causecatastophic results. He eventually left, claiming he was leaving her there. Angered, Rose dismissed his threat and spent the day with her father, getting ready for the wedding he was meant to go to had he not died.

They arrived at the wedding, where the guests present revealed they had lost contact with others meant to come. People around the world began to mysteriously vanish. In a park, a young Mickey Smith fled after the only children also disappeared. Rose and others found their phones would only repeat the same message over and over when they tried to ring people: "Watson, come here, I need you," the very first thing said over a telephone by Alexander Graham Bell.

The Doctor, upon returning to his TARDIS, found the interior had been taken out of time. Realising what was concurring, he raced to the church. Rose also met her mother, Jackie Tyler, and her younger self, discovering her parents' marriage was not as idyllic as her mother made her to believe. The Doctor arrived shortly after, saving Rose from a Reaper. The guests fled into the church, as its age acted as a shield against the reapers. However, it wouldn't last as the Reapers gained more power as they consumed more people. The Doctor guessed the only survivors on Earth were people like them in similar old buildings.

Over time, the Doctor revealed to Rose saving her father had enabled the Reapers to infest reality, where they would cleanse it of everything to fill in the void made by her saving Pete. However, he refused to let Pete die again, attempting to save everyone by using his TARDIS key to pull the TARDIS back into their timeline. However Rose accidentally touched her younger self, enabling a Reaper to enter the church. The Doctor then sacrificed himself and his TARDIS to destroy the Reaper, there last hope lost. The Reapers eventually consumed the whole world.

Negation
Later, Pete noticed the car from earlier that day was stuck in a loop, driving round the church only to vanish. He figured out that the only way to restore the timeline was to allow the car to run him over. He tole Rose, having understood the Doctor had figured it out also, but tried to find another solution to spare Rose losing her father again. After saying goodbye to Rose and Jackie, Pete ran out into the road, avoiding the Reapers and allowed the car to kill him.

As such, a new timeline was created. This time, Rose was by her father as he died and the runaway driver stayed instead, allowing everyone to know who he was. (TV: Father's Day)

Rose later told Jackie she was at her father's side as he died, rather that not so as originally occurred, in an effort to prove to her mother how wonderful the Doctor was. (TV: The Parting of the Ways)
