Eleventh Doctor

"There's one thing you never put in a trap if you're smart. If you value your continued existence, if you have any plans about seeing tomorrow there's one thing you never, ever put in a trap... Me."

- The Doctor

The Eleventh Doctor is the eleventh incarnation of the Time Lord known as the Doctor.

Regeneration
The Doctor's tenth incarnation regenerated after absorbing a vast amount of radiation. Due to this, he released a massive amount of energy during regeneration and this caused severe damage to his TARDIS.

Despite the destruction going on around him inside the TARDIS, the new incarnation's first priority was to do a personal inventory of his body to make sure all the proper parts were in place; in fact, his first words were "Legs! I've still got legs! Good!" after which he kissed one of his knees in relief. He next counted his fingers. The new incarnation was momentarily worried that he had regenerated as female due to having longer hair, until he confirmed the presence of an Adam's apple. He then mentioned "I've had worse" when it came to his nose, seemed unsettled by his chin, and again bemoaned the fact that he was still not ginger something his previous incarnation had also wanted to be. (DW: The Christmas Invasion)

Slightly addled by the regeneration, the new Doctor did not immediately realize the TARDIS was on fire and about to crash. Once he did, he actually seemed to enjoy the thrill of the moment, calling out his new catchphrase "Geronimo!" as his TARDIS plummeted to Earth. (DW: The End of Time)

Meeting Amy Pond and Saving the World
"And the final score is no TARDIS, no screwdriver, 2 minutes to spare. Who da man? (he pauses) Oh I'm never saying that again, fine."

- The Doctor

While the TARDIS is falling and blowing up, the Doctor holds onto the edge of the TARDIS and tries to get back in. When he does, another explosion causes the TARDIS to crash in Amelia Pond's garden and the Doctor falls all the way down into the pool in the library. The Doctor emerges and asks for an apple. After drying off, the Doctor discovers most of the foods he likes he hates now due to his regeneration changing his taste. The only food he likes is fish fingers dipped in custard. After discovering that the crack in Amelia's bedroom wall is a crack in time and a prison and also noticing a perception filtered door, the Doctor hears the Cloister Bell and rans to the TARDIS to stabilize its engines by making a quick jump into the future. He promises young Amelia that he'll return in five minutes. 12 years later, the Doctor materilises the TARDIS and enters Amelia's house and knows where Prisoner Zero is. When he calls for Amelia he gets hit with a cricket bat and is cuffed to a radiator. He wakes and discovers a police officer (Amy) and she enters the perception filtered room and retrieves the Doctor's Sonic Screwdriver and encounters Prisoner Zero. After escaping the house, the Doctor discovers the police officer is Amelia (know called Amy) and that the Atraxi will incinerate Earth in 20 minutes. With sonic screwdriver destroyed, the Doctor figures out a new strategy to save Earth. He uses Jeff's laptop to communicate with Patrick Moore, NASA and many other people and creates a computer virus from Rory's Samsung Tocco Lite which he uses to attract the Atraxi to the hospital where Prisoner Zero is. After calling back the Atraxi and asking them a few questions, the TARDIS key glows and the Doctor races to the TARDIS to check out what it looks like. He then leaves and comes back for Amy, 2 years later before her wedding. He offers to take her anytime and anywhere in the universe and they set off. (DW: The Eleventh Hour)

Personality
At first glance, the Eleventh Doctor is highly energetic and very lively, although if this is just a result of his recent regeneration is currently unknown. He is extremely brash and unafraid to show his eccentricities, appearing to act alien. He is also easily agitated when people or objects do not do as he wishes them to, and will resort to physical confrontation and somewhat reckless behavior to achieve his goals. He has, like a number of his other incarnations, fantastic leadership qualities. Much like his ninth and  tenth incarnations, he also has a large amount of knowledge of Earth slang and colloquialism as he is aware of Facebook, Twitter and Bebo. He appears to have remembered a few of his predecessor's catchphrases, such as "Fantastic!", "There's been some cowboys in here", and repetition of the word "What!". He is extremely resourceful and quick thinking, able to spin things to his point of view, and can find positive outlooks in negative situations.

He also can tell how old something is by taste which was a trademark of the Fifth and  Tenth Doctors. He is often late, arriving twelve years later than he intended, like his fifth,  ninth and  tenth incarnations. He also appears to have incredibly good eyesight as well as an eidetic memory, and is able to scan an entire scene and pick up little details.

Clothes
For most of DW: The Eleventh Hour the Doctor wore the tattered clothes of his previous incarnation from just before he regenerated. After changing into clothes stolen from the hospital changing room, the Doctor's primary outfit consisted of a brown tweed jacket with elbow patches, a fashionable shirt, a bow tie, red braces and rolled up trousers and black boots. He was known to vary the color of his shirt, bow tie and braces.

TARDIS
As a result of the damage caused by his tenth regeneration, the Doctor's TARDIS underwent a metamorphosis. While its interior radically changed, the exterior was also slightly affected. Most noticably, the right exterior door was again emblazoned with a St. John's Ambulance symbol, as it had been on his initial incarnation's TARDIS. The light is now different, the blue is a bit darker and the windows have changed a bit.

Behind the Scenes

 * The comic strip The Crimson Hand, being published in Doctor Who Magazine from issue 416 in December 2009, has been announced by DWM as the last strip to feature the Tenth Doctor. Presumably this means DWM will begin strips featuring the Eleventh Doctor in the early months of 2010 depending on how many issues the Crimson Hand arc covers. Similarly, the American comic book publisher, IDW Publishing, announced at the New York Comic Con in February 2009 that it will begin publishing original comic book adventures featuring the Eleventh Doctor as of issue 18 of Doctor Who Ongoing, scheduled for publication in December 2010.
 * BBC Books has announced that the first novels featuring the Eleventh Doctor in the New Series Adventures line are scheduled for release in April 2010. That month will also see the first BBC Audio adventure for the Eleventh Doctor.
 * During his debut scene, the Eleventh Doctor utters the phrase "Geronimo!" This is later repeated in a scene from a future episode in the official BBC trailer, making it likely that "Geronimo!" will be the new Doctor's equivalent to the Ninth Doctor's "Fantastic!" and the Tenth's "Allons-y!"
 * In Issue 418 of the Doctor Who Magazine, Steven Moffat revealed that the Eleventh Doctor had an entirely different costume lined up before filming for the new series started. The original look had a piratical feel which Benjamin Cook described as "a little like something Captain Jack Sparrow wears in the Pirates of the Caribbean movies". However, Matt Smith was unhappy with the costume, as he felt it reflected how someone else would dress the Doctor, rather than how the Doctor would dress himself. The eventual costume, particulary the bow-tie, was influenced by the attire Patrick Troughton wore as the Second Doctor, after Matt Smith watched Tomb of the Cybermen.
 * The BBC's initial trailer issued in January 2010 includes brief scenes showing future adventures. These include - though the context of these scenes remains at present unknown:
 * Punching a man in the jaw, somewhat clumsily.
 * Exchanging a kiss with Amy.
 * Falling to the floor in a (non-romantic) embrace with River Song.
 * Firing either a pistol or a flare gun.
 * Wearing sunglasses in the dark.
 * Hitting a Dalek with an unattached manipulator arm.
 * The third trailer and preview of The Eleventh Hour from BBC confirms the Doctor doing the following:
 * Arriving in London during WW2
 * Holding onto Amy as she joyfully drifts in space
 * Using his new Sonic Screwdriver at Stonehenge.
 * Telling someone (possibly Amy), "Cause this is what I do, everytime, every day, every second."
