Twelfth Doctor (DarthJacko09)

The Twelfth Doctor is the twelfth incarnation of the Time Lord known as the Doctor. He is seen as a somewhat hybrid of his Tenth and Eleventh Incarnations, retaining the seriousness and wit of the Tenth Doctor along with the zaniness and spontaneity of the Eleventh Doctor.

Appearance
The new Doctor appears youthful like his predecessor, around 24 in human years, with blue eyes and black hair. He wears a long coat like his tenth incarnation and a suit, the first Doctor outfit since the Seventh Doctor to feature question marks on it (one on the collar and two either side).

He carries a fob watch within his sleeve, the same most likely used in his Tenth Incarnation, and has the same sonic screwdriver and TARDIS design to his predecessor. On some occasions (No Tricks, The Doctor and the Demon) he carries a cane with him outside the TARDIS, which Billy comments as making him look old, to which he replies: "I' am". He also wears a cross in the English camp in Phoenixfire.

Personality
The Twelfth Doctor in In The Beginning is proper and greeting when he meets Billy on Earth in 2013. As he is still recovering from his regeneration, he is increasingly erratic when things happen, eg. when he sees the Charth ship in the sky. During the course of his adventures he is generally empathic to those he encounters, except for the Daleks in both New Dublin and Season Nine's The Mercy of the Daleks, where like his predecessors expresses the desire to destroy them entirely, and as the Supreme Patriarch says in The Mercy of the Daleks, he is "worse than the Daleks". He can go from calm and knowledgeable to erratic and violent, as seen in Into the Void and The Infinite Realm where he expresses the hatred he has for Omega, the desire to "kill him". His empathic side is also often seen throughout his adventures, especially in Heart of Wood, where he shows great respect and empathy for the Wooden Cyberman. When the Cyberman asks him to destroy him, the Doctor is saddened, but obliges. He also shows empathy and mercy to the Stranded in New Times In Old London, at first seeing them as enemies to the Earth.

The Twelfth Doctor has an interest in history, as seen in his adventures in season eight (The Doctor and the Demon, Phoenixfire) and season nine (Heart of Wood, Gods and Men). Throughout both seasons he has tried to take the TARDIS to 16th century France on a few occasions, only to be intervened by outside powers. He has expressed his favourite time period is the world circa "sometime BC" as he tells both Billy O'Hara and Isabella Cartwright. Like his predecessors, the Twelfth Doctor has favourite things; his favourite foods are cheese and chocolate cake, and he expresses a minor weakness for jelly babies like his fourth incarnation. In [[I' Am The Doctor]] he loses all recollection of who he is, but Jack remembers the fob watch and uses to restore his memory.

Companions
The Twelfth Doctor has two companions throughout Season Eight (Billy O'Hara and Isabella Cartwright). Billy is introduced as a 26 year old Irish unemployed "no-body", who after assisting the Doctor against the Charth, is invited to join him in the TARDIS. After being marooned on Earth while the Doctor faces the Talons of Faran, Billy decides to stay back on Earth and parts ways with the Doctor.

Isabella Cartwright first appears in Mars and Venus as Doctor Bradley's assistant, and after the events involving the Ice Warriors, and after impressing the Doctor with her skill she joins Billy and him onboard the TARDIS. Isabella is killed at the hands of Omega in The Infinite Realm which drives the Doctor into a mad rage that is a rare emotion with him.

Captain Jack Harkness, an old friend of the Doctor's ninth and tenth incarnations, joins oboard the TARDIS for several adventures (Sands of Kada, The Mercy of the Daleks, I' Am The Doctor and Gods and Men). He remains in ancient Greece at the end of Gods and Men as he believes he fits in, and confirms to the Doctor that he will find a way back to modern day Earth.

Christina is first encountered by the Doctor in the season ten story The Girl and the Monster, where she is being hunted by a Slitheen masquerading as a local MP. She later joins him in the TARDIS. Christina encounters the Daleks in her first time in the TARDIS, in The Survival of the Daleks and The New Breed. In What Ever Happened To Christina? the Doctor is led to believe Christina is dead, but it is an illusion conjured by a time vampire eager for the Doctor's power.
